Description

Device and method for extracting one or more components, in particular cannabinoids such as tetrahydrocannabinol, from a mixture of substances

The invention relates to a device and a method for extracting one or more components, in particular cannabinoids such as tetrahydrocannabinol (THC), from a mixture of substances.

In known devices for extracting essential oils from plant material, plant material is placed in a chamber or bladder of the device. Steam is then introduced into the bladder, preferably at a temperature of 180°C, which dissolves the essential oil from the plant material. Such steam distillation processes are usually operated in batch operation. The process is completed when the temperature of the plant material in the bladder has warmed to the temperature of the water vapor, since no condensation of the water vapor can then take place on the plant material.

A particular disadvantage is that the method depends on the loading of the chamber, since the plant material can be flowed to or overflowed by water vapor to varying degrees depending on the loading height and density, possibly also depending on the chamber dimensions. Plant material located further out is generally provided with significantly better flow, while plant material located further out can be covered by layers of plant material located further out. This means that both the duration of the process and the amount of essential oil extracted can vary greatly. Likewise, an average residence time of the plant material in the bladder or chamber is difficult to set.

It is therefore the object of the present invention to provide a device and a method which enables a more reliable and uniform extraction and in which the residence time can be adjusted more precisely. These disadvantages are overcome by a device according to the invention and the method according to claims 1 and 23. Advantageous embodiments are the subject of the subclaims.

The effect of cannabis extracts is mainly due to the active ingredient tetrahydrocannabinol (THC). The THC content can vary greatly from cannabis plant strain to cannabis plant strain. A THC content of more than 30% is possible in certain cannabis strains under optimal conditions. Depending on the strain, medical cannabis currently offers THC levels between less than 1 and up to 22%. The THC content of official medical cannabis is between less than 0.05 and 10.2%.

In order to achieve optimal THC extract from the cannabis plant, provision can be made to determine the THC qualitatively and/or quantitatively during the growth of the hemp plant in order to be able to precisely determine the harvest time. Sensors can be used for this purpose, in particular at least one infrared sensor. The sensors can be set up to record relevant biological data from the plant and, if necessary, store it in a database.

The device according to the invention and the method according to the invention also allow both batch operation and continuous operation.

The device according to the invention for the extraction of one or more components, in particular THC and / or cannabinoids, from a mixture of substances has a chamber, a plate accommodated in the chamber, at least one nozzle for feeding the mixture of substances into the chamber and a static charging unit, the Static charging unit is designed to statically charge the mixture of substances, the plate having a charge opposite to the static charge of the mixture of substances, so that the statically charged mixture of substances, or at least components thereof, adheres or is liable to the plate.

The static charging unit can be set up to statically charge the mixture of substances supplied and/or to be supplied into the chamber. The static charging unit can be set up to statically charge the mixture of substances before, during and/or after feeding it into the chamber. The statically charged mixture of substances, or at least parts of it, can stick to the plate. The plate can be set up so that it can be brought to a predetermined load. Provision can be made to bring the charge of the plate to a nominal charge periodically or at least at predetermined time intervals. The plate can be designed to reverse its charge.

The mixture of substances can have at least one or more of water, water vapor and/or particles. The particles can be or have hemp particles. The components to be extracted can be components of the particles. Water, water vapor and/or particles can be components of the mixture of substances.

By adhering the mixture of substances and/or components thereof, in particular by adhering the particles, improved overflow, heat transfer and/or mass transfer can be ensured. The mixture of substances, its components and/or particles can be distributed over the entire surface of the plate, so that a large surface area can result for overflow, heat and/or mass transfer. The static charge of the mixture of substances and/or the plate can be selected such that a predetermined layer thickness of mixture of substances can adhere to the plate.

By dissolving the mixture of substances and/or components thereof, in particular the particles, from the plate after the extraction has taken place, the mixture of substances can be removed from the chamber and/or an extraction area. The mixture of substances can be released from the plate, for example, by reversing the charge on the plate. Alternatively or additionally, the plate can be moved or shaken to loosen it. The time of dissolution can correspond to a predetermined residence time. The residence time can be chosen such that a predetermined proportion of extract, e.g. per amount of mixture, is achieved. The mixture of substances released from the plate can fall downwards under the influence of gravity. The mixture of substances released from the plate can be carried out of the chamber through a flap and/or an outlet line.

The plate can be arranged opposite the at least one nozzle, so that the substance mixture supplied through the nozzle can be sprayed in the direction of the plate and/or onto the plate. The device can have a heating unit that can be set up to heat the chamber and/or the plate. The heating unit can be set up to heat the chamber and/or the plate to a temperature of approximately 80°C to 120°C. It can be provided that the extracted extract is evaporated or converted from a liquid phase into a gas phase using the heat provided by the heating unit. The extract may contain essential oil, in particular hemp essential oil.

The heating unit can have a hot air generator and a hot air blower. It can be provided that hot air generated by the hot air generator is introduced into the chamber using the hot air blower via a hot air supply. The hot air can have a temperature of around 150°C to 200°C. Other suitable fluids or gases can also be used instead of hot air.

The heating unit can have a heating wire. The heating wire can be arranged on and/or in the chamber and/or the plate. The heating unit can be or have a jacket heater or the like.

The device can have a condensate collector arranged in the chamber. The condensate collector can be arranged on an upper side of the chamber. The condensate collector can be designed to collect extract condensed in the chamber. The condensate collector can be fluidly connected to a condensate conveyor. Provision can be made for condensate collected in the condensate collector to be injected back into the chamber via the nozzles.

The device can have a tank fluidly connected to the chamber for receiving extract formed in the chamber.

The device can have a cooling unit that can be arranged fluidly between the chamber and the tank. The cooling unit can be set up to liquefy the extract. The device can have a collecting container for receiving and/or forming the mixture of substances, wherein the collecting container can be fluidly connected to the at least one nozzle.

The collecting container heating unit can be set up to heat the collecting container to a temperature of 50 °C to 120 °C.

The device can have a grinder, which can be connected to the collecting container, so that material ground by the grinder, preferably hemp particles, can be introduced into the collecting container.

The device can have a grinder heating unit, which can be set up to heat the grinder. The grinder heating unit can be set up to heat the grinder to a temperature of 40°C to 300°C.

The grinder heating unit can be designed according to the principle of a drum mill or can have a drum mill. Drum mills are used for fine to ultra-fine comminution of various raw materials. They can have a substantially horizontally mounted, cylindrical or cylindrical-conical, rotating drum, which defines a grinding chamber into which the ground material is introduced. Grinding media can be arranged in the grinding chamber and can be heated externally. By rotating the drum, the contents are turned over or overturned, thereby crushing the ground material. Balls made of steel or hard cast iron and steel rods are mainly used as grinding media. If larger pieces of cannabis flower material (ground material) take over the function of the grinding media, this is referred to as autogenous grinding. Continuously operating drum mills usually have openings in the center of the end walls through which the flower material is fed into the grinding chamber or the ground pollen is discharged into a reservoir. The inner walls of the grinding chamber are subject to high stress and are therefore provided with a wear-resistant lining.

The grinder may be housed in a grinder chamber, which may have an air inlet and an air outlet, so that air flows in through the air inlet can flow in the grinder chamber, flow through the grinder, the grinder chamber and / or the material ground by the grinder, and can flow out of the air outlet. The air can be or contain hot air. The air can be or have air with a temperature between approximately 150°C to 300°C.

The device can have a sieve arranged between the collecting container and the grinder. A grid width of the sieve can be chosen such that only particles with a certain maximum size can pass through the sieve. For example, the sieve can have a grid width of less than 500 pm. However, the sieve can also have a grid width of less than 200 pm and/or less than 20 pm. This means that a maximum size of the particles in the mixture of substances can be specified. The extraction can be or will be improved due to the relatively small particle size.

The sieve can be or have a vibrating sieve. Alternatively or additionally, a vibrator can be connected to the sieve so that the sieve can be shaken via the vibrator.

The mixture of substances can contain the substance ground by the grinder, preferably hemp particles. The substance ground by the grinder, preferably hemp particles, can be a component of the substance mixture. The fact that the particles of the mixture containing the components to be extracted are or can be comminuted can result in improved extraction.

The collecting container can have an inlet for supplying a fluid, wherein the fluid can have the mixture of substances and/or an extractant which can form the mixture of substances with the ground particles in the collecting container. The extractant can be or have water and/or water vapor. The extractant can be a component of the mixture of substances.

The plate can be movably accommodated in the chamber. The plate can be attached with a suspension. The suspension can have a spring element or the like. The suspension can be designed to allow movement of the plate. The device can have a shaking device which can be set up to shake the plate. The device can have a control unit for controlling a temperature of the chamber and/or the plate, for controlling the supply of the mixture of substances and/or for controlling the static charge of the mixture of substances and/or the plate. The control unit can be set up to control the extraction process. For this purpose, the control unit can control or regulate one, several or all controllable parts such as conveyor units, valves, heating elements, flaps, mills or the like of the device.

The device can have at least one temperature sensor arranged on or in the chamber. At least one, several or all of the temperature sensors can be connected to the control unit.

The device can have at least one optical sensor arranged on or in the chamber. The optical sensor can be or have a camera. The optical sensor can be connected to the control unit.

According to a further aspect, the invention relates to a method for extracting one or more components, in particular THC and/or cannabinoids, from a mixture of substances, comprising the following steps: feeding a mixture of substances into a chamber of a device for extraction; Static charging of the mixture of substances with a static charge using a static charging unit; Adhesion of the statically charged substance mixture or at least components thereof to a plate held in the chamber and charged with a charge opposite to the static charge; Dissolving the substance mixture adhering to the plate or its components from the plate after a specified adhesion time has elapsed. The adhesion time can correspond to a residence time. The adhesion time can be specified.

The order of several steps can be interchanged. For example, the static charging can be carried out before the mixture of substances is supplied.

Detaching from the plate may involve shaking the plate. Alternatively or additionally, release from the plate may include reversing the charge of the plate. The chamber and/or plate can be heated to a temperature of approximately 80°C to 210°C.

An extract formed in the chamber can be exported from the chamber. The extract formed can be cooled and/or liquefied.

The cooled and/or liquefied extract can be separated. For this purpose, for example, a vacuum extraction process can be provided or carried out.

The mixture of substances can be formed in a collecting container and/or fed into the chamber from a collecting container. The mixture of substances can comprise at least one of particles, water and/or water vapor. The particles can be or have hemp particles.

The particles can be ground with a grinder and fed to the collection container. The particles can be ground by the grinder in such a way that they can have an average size of less than 500 pm, preferably less than 200 pm, particularly preferably less than 20 pm.

The particles ground by the grinder, in particular hemp particles, can be flowed through by air before being fed to the collecting container. Hot air can flow through the particles. The particles can be flowed through by air with a temperature between around 150 °C and 300 °C. Flowing through the particles can include flowing around or over the hemp particles.

The particles ground by the grinder can be sieved by a sieve before being fed to the collecting container. The particles can be sieved by a vibrating sieve. Sieving can ensure that only particles with a maximum size can be used in the process.

The collection container can be heated to a temperature of around 50 °C to 120 °C. The method can be carried out using a device described above.

The invention is further explained using the following figures. Show:

1 shows a first embodiment of a device according to the invention;

Fig. 2 shows a second embodiment of a device according to the invention;

Fig. 3 shows a third embodiment of a device according to the invention.

Figure 1 shows a first exemplary embodiment of a device 1 according to the invention. The device 1 has a chamber 8, a plate 7, at least one nozzle 5 and a static charging unit 6. The plate 7 is arranged in the chamber 8. A mixture of substances 4 can be introduced into the chamber 8 via a feed line 10. The supply line 10 can be fluidly connected to the at least one nozzle 5, so that the mixture of substances 4 can be sprayed into the chamber 8.

The chamber 8 and/or the plate 7 can be heated. The device 1 can have a heating unit for this purpose. For example, the heating unit can have a heating wire 19. The heating wire 19 can include a heating coil and/or heating coil. The heating wire 19 can, for example, be guided through the interior of the plate 7. Alternatively or additionally, the heating wire 19 can be arranged in the chamber 8 or around it. Alternatively or additionally, the heating unit can heat the chamber 8 and/or the plate 7 using hot air. For this purpose, the device 1 can have a hot air supply 13, by means of which hot air can be introduced or carried out into the chamber 8 and/or the plate 7. The hot air supply 13 can be suitably routed. In an embodiment not shown, the hot air supply 13 can be guided through the plate 7 in a serpentine manner, for example. However, it can also be provided that hot air is introduced into the chamber 8 through the hot air supply 13. For example, the heating unit can have a hot air generator 40 and/or a hot air blower 39, see FIG. 3. Instead of hot air, another suitable fluid can also be used, by means of which the heating unit can heat the chamber 8 and/or the plate 7. Alternatively or In addition, the heating unit can be or have a jacket heater, which can heat an inner wall of the chamber 8, for example.

The heating unit can be set up to heat the plate 7 and/or the chamber 8 to a temperature of approximately 80 ° C to 120 ° C. The hot air can have a temperature of around 80°C to 120°C.

The plate 7 can be arranged in the chamber in such a way that it can be arranged essentially opposite the nozzles 5 and/or lying in the spray direction. This can result in a good distribution of the substance mixture 4 to be sprayed on the plate 7.

The mixture of substances 4 can contain water, water vapor and/or particles. The particles can in particular be or have hemp particles. The particles can be or have ground or otherwise comminuted particles. The particles can contain the components to be extracted.

The particles can in particular contain THC and/or cannabinoids, which can be extracted using the device 1 and/or the corresponding method. The particles can contain, for example, A ⁹ -THC. Cannabinoids can include cannabigerol (CBG), cannabichrome (CBC), cannabidiol (CBD), cannabinodiol (CBND), tetrahydrocannabinol (THC), cannabinol (CBN), cannabitriol (CBT), cannabielsoin (CBE), isocannabinoids, cannabicyclol (CBL), Include cannabicitran (CBT) and/or cannabichromanone (CBCN).

Extraction can be done by evaporation and subsequent condensation. In the chamber 8, the mixture of substances 4 can be heated or kept at the same temperature. The water and/or the water vapor can serve as a solvent for extracting components contained in the particles. The water vapor can contain at least one solvent. This makes it possible to extract the THC or CBD from the flowers. The most commonly used solvents are propane, C0 ₂ , isopropyl alcohol, dimethyl ether, ethanol and butane. At the end of the process, these contain the ingredients of the plant, such as THC or CBD. Depending on the type of plant, the concentration of THC or CBD in the solvent can be between 70% and 99% by volume. For example, the water vapor can condense on the particles, for example if the particles have a lower temperature than the water vapor or are cooler. The condensed water can wet the particles, with substances contained in the particles, for example essential oils, in particular essential hemp oils, being able to diffuse out of the particles. This can result in an oil-water mixture. It can be provided that the condensation of the water vapor on the particles takes place before they are fed into the chamber 8. The condensation can take place, for example, in a collecting container 34, see for example Figure 2. The mixture of substances 4 can have or be the oil-water mixture. The oil-water mixture can evaporate when heated. Provision can be made to introduce the oil-water mixture into the chamber through the nozzles 5. This heating can take place in the chamber 8, for example preferably on the plate 7. The mixture of substances 4, in particular the oil-water mixture, can be evaporated in the chamber 8, preferably on the plate 7. The particles, or at least residual components or non-evaporated components of the particles, can remain behind. The evaporated oil-water mixture and/or the evaporated substance mixture 4 can rise upwards under free convection and be carried out as an extract 35 from the chamber 8 and/or the device 1 via a removal line 2.

Alternatively or additionally, it can also be provided that the water of the mixture of substances 4 evaporates in the chamber 8, for example in particular on the plate 7, and thereby dissolves the substances or components from the particles. The extract formed in this way can be carried out from the chamber 8 or the device 1 via the extraction line 2.

Alternatively, the mixture of substances 4 supplied to the chamber can include the particles, but have no solvent, in particular no water and/or water vapor. After supplying the mixture of substances 4 or the particles into the chamber 8, steam and/or water can then be supplied to the chamber as a solvent. The water and/or the water vapor can wet the particles, dissolve the substances from the particles and then be carried out as an extract 35 from the chamber 8 or the device 1 via the extraction line 2. It can be provided that water vapor can first condense on the particles as described above. Provision can also be made to use a solvent other than water and/or steam.

The extract 35 can have the evaporated oil-water mixture and/or the evaporated substance mixture 4. It can be provided that the extract 35 and/or the evaporated substance mixture 4 does not include the remaining components of the particles or their non-evaporated components. The remaining components of the particles or their non-evaporated components can be removed from the chamber 8 or the device 1 via a flap 22 and/or an outlet line 3.

Since the partial vapor pressures of the oil-water mixture can add up, evaporation can be achieved just below 100°C. Due to the low evaporation temperature, the aroma of the extract 35 or its components can be improved and/or preserved.

It can be provided that the internal pressure of the chamber 8 essentially corresponds to atmospheric pressure or is approximately 1 bar. It can also be provided that there is a vacuum or a pressure of up to 100 bar in the chamber. It can be provided that the temperature inside the chamber 8 and/or the temperature of the plate is between approximately 80°C and 120°C.

The static charging unit 6 is set up to statically charge the mixture of substances 4. The static charge can take place before the substance mixture 4 is fed into the chamber 8, when it is fed into the chamber 8, or after it is fed into the chamber 8. The static charging unit 6 can be arranged accordingly. For example, the static charging unit 6 can be arranged in the chamber 8. The static charging unit 6 can charge the mixture 4 positively or negatively. The static charge can be an electrostatic charge. For example, the static charging unit 6 can be set up to generate an electric field through which the mixture of substances 4 can be passed. Alternatively or additionally, the static charging unit 6 can be arranged fluidly downstream of the nozzle 5, so that the substance mixture 4 can be sprayed through the static charging unit 6 and/or an electric field generated by the static charging unit 6. When the mixture of substances 4 is passed through and/or sprayed through the electric field, the mixture of substances 4, in particular particles contained in the mixture of substances 4, can become statically charged. The mixture of substances 4, in particular particles contained in the substance mixture 4, can be statically charged by the static charging unit 6 by means of field charging.

The plate 7 has a charge opposite to the static charge of the mixture 4. For example, if the mixture of substances 4, for example particles thereof, is negatively charged, for example by the static charging unit 6, then the plate 7 can be positively charged. For example, if the mixture of substances 4 is positively charged, the plate 7 can be negatively charged. This allows the statically charged mixture of substances 4, for example particles of the mixture of substances 4, to adhere to the plate 7, for example due to the Coulomb force. The static charge of the mixture of substances 4 and the charge of the plate 7 can be chosen appropriately. For example, the static charging unit 6 and/or the plate 7 can be controlled or regulated accordingly. For example, it can be provided to suitably select or control the composition of the mixture of substances 4, in particular the proportions or weight proportions of its components, the particle size, the strength of the electric field and/or the charge of the plate 7.

By adhering the mixture of substances and/or components thereof, in particular by adhering the particles, improved overflow, heat transfer and/or mass transfer can be ensured. In particular, this can ensure that the particles containing the components to be extracted do not collect at the bottom of the chamber 8, but can be evenly distributed on the plate 7. This can result in improved extraction. The static charge of the mixture of substances 4 and/or the plate 7 can be selected or controlled in such a way that a predetermined layer thickness of the mixture of substances 4 can adhere to the plate 7. It can be provided that the layer thickness is selected, for example, depending on a predetermined residence time, the adhesion time and/or the heat and mass transfer through the layer or the like.

It can be provided that the mixture of substances 4 adhering to the plate 7 and/or particles of the mixture of substances 4 are released from the plate 7. Loosening can be done, for example, by shaking or moving the plate 7. Alternatively or additionally, the charge of the plate can be reversed so that it corresponds to the charge of the mixture of substances 4, whereby the mixture of substances 4 can be detached from the plate 7. If the device is operated in a batch mode, it can be provided that the dissolving is carried out at a predetermined time after the substance mixture 4 has been sprayed in. If the device is operated continuously, loosening can be provided to be carried out periodically. The time and/or the period duration or the adhesion time can be selected such that it corresponds to a predetermined residence time. The residence time and/or the adhesion time can be selected such that a predetermined proportion of extract, for example per amount of mixture, is achieved. The mixture of substances released from the plate can fall downwards under the influence of gravity. The mixture of substances released from the plate can be carried out of the chamber through a flap and/or an outlet line.

The residence time and/or the adhesion time can depend or be selected on the particle size, the temperature of the plate 7 and/or the chamber 8, the amount of solvent or the amounts or weight proportions of the components of the mixture of substances and/or the components to be extracted.

The plate 7 can be arranged to be movable with a suspension 30, so that the plate 7 can be shaken to loosen the mixture of substances 4 and/or particles adhering to it. For example, the plate 7 can be fastened via the suspension 30, for example with an inside of the chamber 8. However, it can also be provided that the suspension and / or the fastening of the plate is not arranged in the chamber 8, in particular not with a mixture of substances 4 can come into contact and/or is not fluidly connected to the chamber 8.

The device 1 can have a flap 22, by means of which the mixture of substances 4 fed into the chamber 8 and/or the mixture of substances 4 dissolved from the plate 7, in particular particles thereof, can be removed from the device 1 and/or the chamber 8. Alternatively or additionally, the device 1 can have an discharge line 3 through which the mixture of substances 4 can be discharged from the chamber 8. A valve 12 can be arranged in the outlet line 3, by means of which the outlet line 3 can be opened and/or closed. The valve 12 can be connected to a control unit so that the valve 12 can be controlled, in particular opened or closed.

The device 1 can have a condensate collector 31. The condensate collector 31 can be designed to collect condensate formed in the chamber 8. The condensate collector 31 can be arranged on an upper side of the chamber 8. It can be provided that condensate formed on the top of the chamber 8 is collected by the condensate collector 31 or is collected. The condensate collector 31 can be fluidly connected to a condensate conveyor 11. The condensate conveyor 11 can be or have a pump. The condensate conveyor 11 can be set up to transport away condensate collected in the condensate collector 31. For example, the condensate collected by the condensate collector 31 can be exported from the device 1. Alternatively or additionally, the collected condensate can be mixed into the mixture 4 and/or reintroduced into the chamber 8 of the device 1.

The condensate can be filled into capsules within the device. The capsules can be inserted into a tube-like magazine in a vaporizer. The capsules can be heated separately so that the condensate (active ingredient) can be administered in portions. When activating the heating unit and inhaling, fresh air can be mixed into the aerosol. A further embodiment of the invention provides that the device described or parts thereof are accommodated in a vaporizer or inhaler. Through oral consumption or by evaporating the condensate produced in a vaporizer, there is no strain on the respiratory tract by avoiding carcinogenic substances formed during combustion. Combustion does not take place with the new process.

The device 1 can have at least one temperature sensor 17, which can measure a temperature of the chamber 8 and/or the plate 7. At least one temperature sensor 17 can be arranged in or on the chamber 8 and/or the plate 7. It can be provided that temperature sensors 17 are arranged vertically in the height direction of the chamber 8. The temperature sensor 17 can be connected to the control unit so that the control unit can detect temperature values measured by the temperature sensor 17.

The collecting container heating unit can be or have, for example, a hot wire and/or a jacket heater.

The device 1 can have a grinder 15. The grinder 15 can be arranged in a grinder chamber 16. Substance to be ground picked up in a container 46 can be fed to the grinder 15 and ground into particles by it. It can be provided that the ground particles have an average grain size and/or average particle diameter of less than 500 pm. It can be provided that the ground particles have an average grain size and/or average particle diameter of less than 200 pm.
