Definitions

  • the invention relates to a cleaning system for cleaning goods and a method for drying goods.
  • the items to be washed are cleaned in a cleaning system using a cleaning fluid. After the cleaning process, the items to be washed are at least partially wetted with the cleaning fluid and must therefore be dried for further use.
  • the items to be cleaned can, for example, be dried in the air.
  • Mechanical drying with a drying agent is also conceivable. Both processes, however, are complex and time-consuming. The drying process after cleaning in such a system takes a long time and is therefore inefficient. It is also possible that the items can become contaminated again when they are dried using a drying medium, such as a drying cloth.
  • the problem is solved by a cleaning system for goods and by a method for drying goods according to the independent patent claims.
  • the object is achieved in particular by a cleaning system for cleaning goods.
  • the cleaning system comprises a cleaning room for receiving goods to be cleaned. At least one cleaning fluid introduction device for introducing cleaning fluid is formed in the cleaning room.
  • the cleaning system also has at least one steam supply device through which superheated and/or saturated steam can be fed into the cleaning room.
  • the cleaning system also has at least one steam outlet through which superheated and/or saturated steam can be discharged from the cleaning room.
  • the goods can be pharmaceutical and/or laboratory goods.
  • the cleaning fluid introduction device can comprise a washing arm. Alternatively or additionally, the cleaning fluid introduction device can comprise one or more nozzles.
  • Superheated steam is steam that has been heated above the boiling point of the steam medium.
  • Superheated steam has a higher specific heat capacity than air.
  • Superheated steam can therefore introduce or apply more thermal energy into the cleaning room and thus to the goods.
  • a cleaning fluid can consist essentially of water.
  • a cleaning fluid can also contain other liquids or solids such as detergents or disinfectants.
  • the steam can be water vapor.
  • the steam can, for example, have a temperature of 130° to 200°.
  • Such superheated steam can carry a high thermal energy for heating the goods and/or for drying and transfer it to the goods to be dried and thus quickly heat and/or dry the goods to be dried. Drying energy is heat energy, which is also referred to as thermal energy and is used in this case for drying and heating goods.
  • the steam is superheated and under pressure when it is introduced into the cleaning room.
  • the steam expands and cools down.
  • the steam is introduced before the drying process, when the goods and/or the cleaning room are still cold, and condenses, heating the goods and the interior of the cleaning room.
  • the condensation energy released is transferred to the system and the items being washed in the form of thermal energy.
  • the goods and the cleaning room are then heated to a drying temperature, initially by the steam and by the hot water droplets condensing from the steam, which settle on the inside wall of the cleaning room and on the goods. It is possible that when the system is heated up, very hot water remains in the system.
  • the steam is introduced into the cleaning room in such a superheated state that it remains superheated even after the cooling and expansion process. is designed so that no water droplets condense out of the steam. At least a partial condensation of the steam takes place first, until the goods and/or the cleaning room are heated to the drying temperature. The steam is then fed into the heated cleaning room at such a superheat that no more water droplets fall out. The goods and/or the cleaning room are thus heated first and then the drying takes place.
  • the steam can, for example, be introduced into the cleaning room at a pressure of 3 bar.
  • the pressure of the steam then assumes the ambient pressure of 1 bar if the system is located at sea level. If the system is located at a greater level above sea level, the ambient pressure is slightly lower. However, the system is designed in such a way that the ambient pressure surrounding the system is essentially always present in the system. If the superheated steam is introduced into the cleaning room at a pressure of 3 bar, the pressure therefore drops by essentially 2 bar to a pressure of 1 bar, which is present in the system.
  • the pressurized steam which is introduced into the cleaning room in a flow-dynamic manner, acts on the goods and also at least partially removes the cleaning fluid film on the goods, as the superheated steam introduced in a flow-dynamic manner entrains the water particles of the cleaning fluid film.
  • the water particles are moved away from the goods by the flow-dynamic introduction of the steam and the exposure of the goods to the steam and the entrainment of water particles by the steam.
  • the superheated steam then heats the cleaning fluid film on the cleaning goods and simultaneously the superheated steam, which has a speed, removes the cleaning fluid film or the Cleaning fluid drops are entrained onto the goods.
  • the two effects of entrainment of the cleaning fluid and evaporation of the cleaning fluid thus overlap, whereby the effects complement and support each other when drying the goods.
  • a pressure relief valve is provided in the cleaning chamber.
  • a pressure relief valve relieves pressure from the cleaning chamber when the pressure in the cleaning chamber exceeds a certain pressure threshold. This ensures that essentially no overpressure occurs in the cleaning chamber and the system can be operated safely.
  • the wall of the cleaning chamber can be made essentially of stainless steel.
  • the washing arm can be made of plastic or stainless steel.
  • the wall of the cleaning chamber and/or the washing arm can also be made of other materials or of several materials.
  • the crucial thing is that the components of the cleaning system are made of a heat-resistant, corrosion-resistant and robust material. It is also possible for the cleaning system to comprise several materials.
  • the cleaning chamber can be essentially cuboid-shaped. It is possible for several cleaning fluid introduction devices to be formed in the cleaning chamber. It is also possible for several washing arms to be formed in the cleaning chamber. It is possible for one washing arm to be formed in an upper area and one in a lower area of the cleaning chamber. It is also possible for two washing arms to be formed in an upper area and one in a lower area of the cleaning chamber. It is possible that the steam supply device is at least partially formed in the cleaning fluid introduction device and/or in a laundry carrier.
  • Such an arrangement of the steam supply device ensures that the cleaning system is simple and has a small number of components. This prevents defects and enables easy maintenance of the system.
  • the steam supply device is formed in the cleaning fluid introduction device, at least partially only one line for the steam supply and one for the supply of the cleaning fluid is required.
  • the goods can initially be arranged in the cleaning room.
  • the goods are then cleaned by introducing the cleaning fluid.
  • Steam is then introduced into the cleaning room via the steam supply device and the cleaning fluid introduction device. It is possible that the cleaning room and/or the goods are initially heated by the steam, although steam can certainly condense out.
  • the steam and the hot water droplets condensing out on the goods and/or on the inside wall of the cleaning room heat the wall of the interior and/or the goods to a drying temperature. Further steam is then introduced into the cleaning room via the steam supply device. This dries the goods.
  • the goods are therefore heated first and then dried.
  • the washing arm can be movable.
  • the washing arm can be pivotable. It is also possible for the washing arm to be mounted so as to rotate about a rotation axis.
  • the steam supply device is at least partially formed in the washing arm, the steam which is fed via the Steam supply devices and the washing arm are introduced into the cleaning room, can be distributed advantageously and the goods can be advantageously exposed to the steam. This ensures a particularly thorough, effective and efficient drying process.
  • the steam supply device can be formed in a laundry carrier.
  • the laundry carrier can, for example, have steam-carrying pipes in which the steam supply device is at least partially formed. This makes it possible to introduce steam into places in the goods that are difficult to access, for example into a test tube. By arranging the steam supply device in this way, even places in a laundry carrier that are difficult to access can be cleaned and dried.
  • the steam supply device may comprise a steam inlet in the upper area and/or in the lower area of the cleaning chamber.
  • Such an arrangement of the steam inlets of the steam supply device ensures a uniform exposure of the goods, which can be exposed to steam and dried particularly evenly and preferably from the lower area and from the upper area.
  • the upper area of the cleaning room is the area of the cleaning room which is essentially located in the area of the upper wall in the interior of the cleaning room.
  • the lower area of the cleaning room is the area which is essentially located in the area of the lower wall in the interior of the cleaning room. It is possible for the steam outlet to be connected to an extraction device. The extraction device can extract the steam from the cleaning room through the steam outlet.
  • Such an extraction device makes it possible to extract the steam from the cleaning room before the steam cools down to the condensation temperature.
  • the extraction device can be designed as a fan, for example. It is possible for the extraction device to comprise several fans.
  • the steam outlet is located in the lower area and/or in the upper area of the cleaning chamber.
  • the steam supply device prefferably has at least three steam inlets through which steam can be introduced into the cleaning room.
  • the steam inlets can be designed as nozzles.
  • the goods can then be exposed to steam in a targeted manner if the position of the goods can be essentially anticipated, for example because a laundry carrier is designed in such a way that a certain area of the laundry carrier is intended for receiving a certain item.
  • the system prefferably has a gas supply device, whereby a gas can be supplied into the cleaning chamber through the gas supply device. It is also possible for the gas to be actively supplied into the cleaning chamber through the gas supply device.
  • a gas can also be a gas mixture, for example air. It is possible that the gas or gas mixture can be introduced into the cleaning room heated or cooled.
  • the gas can also be nitrogen or carbon dioxide, for example. It is also possible that the gas is dried air. It is possible that the steam outlet with an extraction device is located in the upper area of the cleaning system and that there is an air supply device in the lower area of the cleaning system.
  • the superheated steam in the cleaning room can then be simultaneously extracted by the extraction device and displaced by the gas that is introduced into the cleaning room via the gas supply device.
  • the gas supply device may comprise a gas heating device, whereby a heated gas can be supplied into the cleaning chamber through the gas supply device.
  • the gas heating device can be connected to the steam outlet for thermal purposes.
  • Such a gas supply device with a gas heating device ensures that any residual moisture in the cleaning room or on the items to be cleaned can be absorbed and removed by the heated air.
  • the gas heating device can be thermally connected to the steam outlet, for example via a heat exchanger.
  • thermal energy contained in the steam that is passed through the steam outlet is transferred via the gas heating device to the gas that is introduced into the cleaning chamber. This increases the energy efficiency of the system and thus reduces operating costs.
  • the cleaning system may include a steam generator that can produce superheated steam.
  • the system does not have to be connected to an existing, external steam line and the system can be operated independently of an external steam line.
  • the steam generator can comprise a heater.
  • the steam generator can also comprise a superheat heater. A fluid is then heated by the heater until the fluid evaporates into a gas and the superheat heater further heats the fluid that has evaporated into a steam, so that superheated steam is produced, which can be introduced into the cleaning chamber.
  • the steam supply device can comprise at least one steam connection to which an external steam line can be connected.
  • This type of connection allows the system to be connected to an existing external steam line in a simple and straightforward manner. Since steam lines are often present in the pharmaceutical sector, the system can be easily integrated into existing systems if the existing system has a suitable steam heating system.
  • At least one temperature sensor can be formed in the cleaning chamber, wherein a temperature in the cleaning chamber can be determined by the temperature sensor.
  • the temperature in the cleaning room can be determined using such a temperature sensor. Since, as previously described, the system is essentially at ambient pressure, the condensation point of the superheated steam in the cleaning room can also be determined.
  • the system prefferably has a control system and for the temperature sensor to be connected to the steam outlet via the control system. Then, during the drying process, when the steam has cooled to a temperature just above the condensation point, this temperature can be determined by the temperature sensor and the control system can use the data from the temperature sensor to cause the steam to be sucked out of the cleaning room and/or displaced before the steam condenses.
  • the temperature sensor can also be used to measure the temperature before the drying process, when the cleaning room and/or the goods are initially heated. This makes it possible to determine when the cleaning room and/or the goods have reached the drying temperature. The temperature sensor can therefore be used to determine the point in time at which the drying process can begin.
  • Such a temperature sensor and control system ensure that the system can be operated reliably can be and the goods are dried as best as possible.
  • this temperature can be determined by the temperature sensor and the control system can use the data from the temperature sensor to cause more steam to be introduced into the cleaning room so that the temperature in the cleaning room always remains above the condensation temperature of the steam during drying. While more steam is being fed into the cleaning room, steam which was already introduced can be discharged via the steam outlet. This ensures that no excess pressure builds up in the cleaning room.
  • the object of the invention is further achieved by a method for drying and/or cleaning goods.
  • the method comprises the following steps:
  • the goods may be pharmaceutical and/or laboratory goods.
  • the facility may be a facility as described above.
  • the goods can be subjected to steam in addition to applying a cleaning fluid during the cleaning process. It is possible for the goods to be exposed to cleaning fluid and steam alternately during the cleaning process. It is possible for the goods to be exposed to cleaning fluid and steam simultaneously during the cleaning process.
  • the goods can be exposed to steam and cleaning fluid via the washing arm(s) and/or a wash item carrier.
  • the high speed of the steam exiting the steam outlet means that dirt on the surface of the goods being cleaned can be loosened by the steam. The loosened dirt can then be bound by the cleaning fluid and carried away.
  • By alternately applying steam and cleaning fluid to the goods dirt is loosened several times by the steam and carried away by the cleaning fluid. This produces a very thorough cleaning process with a high quality result.
  • the steam will at least partially condense in the cleaning room during cleaning.
  • the optional process step of removing the steam from the cleaning room above the condensation point of the steam therefore takes place after the cleaning process, when the goods are dried. During the cleaning process, it is therefore possible that the steam will condense in the cleaning room.
  • condensation of the steam in the cleaning room is undesirable and is largely prevented by the process.
  • the at least partial condensation of the steam causes hot water droplets to deposit on the goods and/or on the inner wall of the cleaning room. The heat energy is transferred from the hot water drops to the goods and/or the inner wall of the cleaning room.
  • the steam outlets in the cleaning room are arranged in such a way that the steam reaches particularly dirty areas on the goods.
  • the goods can then be exposed to steam and cleaned in a particularly advantageous manner.
  • the system can be operated cost-effectively and in an environmentally friendly manner.
  • the cleaning fluid is circulated with a pump during the cleaning process.
  • the cleaning fluid can then be used for several cleaning processes. It is possible that the goods are exposed to cleaning fluid and then exposed to steam in order to loosen dirt from the goods. The goods can then be exposed to circulated cleaning fluid, whereby the dirt loosened by the steam is absorbed and removed by the circulated cleaning fluid. It is possible that the cleaning fluid is filtered during circulation.
  • the circulation of the cleaning fluid can be interrupted by stopping the power supply to the circulation pump and/or by stopping a circulation valve.
  • the cleaning fluid is heated during the process or before the process. It is possible that the cleaning fluid is provided with cleaning chemicals before the process or during the process.
  • the steam that is introduced into the cleaning room through the cleaning fluid line can be saturated steam.
  • Saturated steam is saturated steam.
  • Saturated steam has a high specific heat capacity. This means that saturated steam can transport thermal energy well.
  • Forming the steam that is introduced into the cleaning room through the cleaning fluid introduction device as saturated steam ensures that a high level of thermal energy can be introduced into the cleaning room through the saturated steam in order to clean the goods and/or the To heat and/or dry the cleaning room.
  • the formation of the steam, which is introduced into the cleaning room through the cleaning fluid line, as saturated steam thus ensures an effective and efficient drying process.
  • saturated steam is designed as saturated steam in the cleaning fluid introduction device and is introduced into the cleaning room as saturated steam from the cleaning fluid introduction device. If the pressure in the cleaning fluid introduction device is 3 bar and the pressure in the cleaning room is 1 bar, the saturated steam in the cleaning fluid introduction device has a pressure of 3 bar and during the introduction process the pressure of the steam drops from 3 bar to a pressure of 1 bar.
  • the steam flows quickly and/or turbulently onto the goods.
  • the fast and/or turbulent flow supports the drying process. It is possible that water droplets on the goods are carried along by the fast and/or turbulent flow and are thus mechanically moved away from the goods by the flow of steam.
  • the steam expands and cools down.
  • the saturated steam which flows into the cleaning chamber through the cleaning fluid introduction device becomes superheated steam during the flow. Even if saturated steam is formed in the cleaning fluid introduction device, after the introduction process superheated steam and essentially no saturated steam is formed in the cleaning chamber.
  • the water vapor can be exhausted through the steam outlet and simultaneously or periodically a gas can be supplied into the cleaning space through a gas supply device.
  • Simultaneous means that the extraction of water vapor and the supply of gas occur as simultaneously as possible. Of course, it is possible that the extraction of the water vapor and the supply of the gas take place with a slight time delay.
  • This type of process ensures that the superheated steam in the cleaning chamber is kept at a temperature that is just above the condensation temperature and can then be quickly removed. If the steam is removed more slowly, the steam would have to be introduced into the cleaning chamber at a hotter temperature because otherwise there is a risk that the steam will condense during the slow removal process. If the temperature of the steam to be introduced is constant, it is possible to keep the steam in the cleaning chamber for longer before condensation with a faster removal process.
  • Such a process step therefore extends the drying time and/or reduces the temperature of the steam to be introduced. Such a process step therefore improves the drying time and thus the drying result and/or reduces the temperature of the steam to be introduced and thus also the energy consumption of the system.
  • a steam outlet is formed in the lower area and in the upper area of the cleaning chamber and the steam supply device is formed in the upper area and a gas supply device is formed in the lower area and when the steam is introduced into the cleaning chamber in the upper area, gas is discharged via the steam outlet in the lower area and after drying is complete, the steam is discharged from the cleaning chamber via the steam outlet in the upper area.
  • a gas can be introduced into the cleaning area in the lower area through the gas supply device. It is possible that the goods are dried further by introducing the gas, in which residual moisture on the goods evaporates and is carried away by the gas. It is possible that the steam is sucked away via the steam outlet in the upper area. It is possible that simultaneously with the suction, gas is supplied through the gas supply device in the lower area of the cleaning room, which at least partially displaces the steam.
  • Rapid introduction and removal of steam is extremely important so that the steam is evenly distributed in the cleaning room and does not condense in areas where it remains in the cleaning room for a longer period of time during a longer introduction and/or removal process. Rapid introduction of steam into the cleaning room ensures that the steam is evenly distributed. Rapid introduction of steam also creates a fast and/or turbulent flow, which entrains water droplets on the goods and mechanically moves them away from the goods. This speeds up the drying process.
  • Discharging the steam via a steam outlet which is arranged in the upper area of the cleaning room, is advantageous because the superheated steam collects at the steam outlet due to the heat of the steam in the upper area of the cleaning room.
  • the effect of the steam outlet is thus increased by the thermal rise of the steam towards the upper area.
  • a simultaneous introduction of the gas in the lower area of the cleaning chamber through the gas supply device ensures that the steam is not only discharged or sucked away via the steam outlet, but also that the superheated steam in the cleaning chamber is simultaneously displaced by the gas that is introduced in the lower area through the gas supply device.
  • Such a process ensures that the superheated steam can be introduced into the entire cleaning chamber simply and easily, and thus the goods are evenly exposed to superheated steam and dried.
  • Such a process also ensures that the superheated steam can be quickly extracted from the cleaning room at a temperature that is above the condensation point of the steam. Such a process therefore significantly shortens the drying time and is therefore extremely effective.
  • a temperature sensor can be arranged in the room and the temperature in the cleaning room can be determined by the temperature sensor.

  • the gas which is pumped into the heat exchanger 15 via the blower 22 of the gas supply device 13 is thermally connected to the superheated steam which is discharged from the cleaning chamber 3 via the steam outlet 7 which is arranged in the upper region 10.
  • the superheated steam which is displaced from the cleaning chamber 3 and fed into the heat exchanger 15 thus gives off thermal energy to the gas which is fed into the heat exchanger 15 by the blower 22 in the gas supply device 13. This ensures that the thermal energy of the superheated steam can be utilized and the system 1 therefore operates in an energy-efficient manner.
  • Figure 6 shows a cleaning system 1 analogous to Figure 5.
  • the blower 22 is arranged as a suction device 12 in the steam outlet 7, which is arranged in the upper region 10 of the cleaning chamber 3.
  • the saturated steam is thus sucked out of the upper region 10 of the cleaning chamber 3 via the blower 6 and the steam outlet 7, and heated air is fed into the lower region 11 of the cleaning chamber 3 via the gas supply device 13, which leads through the heat exchanger 15.
  • Figure 7 shows a cleaning system 1 analogous to Figure 1.
  • the cleaning system 1 in Figure 7 comprises a circulation pump 29 as well as a first valve 30, a second valve 31 and a third valve 32.
  • cleaning fluid can be sucked out of the cleaning chamber 3 by the circulation pump 29 and introduced into the cleaning chamber 3 through the first valve and the cleaning fluid introduction devices 4, the washing arms 5 and the steam inlets 8.
  • the second valve 31 is arranged in the cleaning fluid introduction device 4.
  • the third valve 32 is arranged in the gas supply device 13 and in the steam outlet 7, which connect to the lower region 11 of the cleaning chamber 3. While the circulation pump 29 pumps cleaning fluid, the first valve 30 is open and the second valve 31 and the third valve 32 are each closed. After the cleaning fluid has been circulated and the goods 2 have been exposed to the cleaning fluid, the first valve 30 is closed and the second valve 31 is opened.
  • the goods 2 are exposed to steam from the external steam line 18, via the steam connection 17, the cleaning fluid introduction device 4 and the steam inlets 8 in the washing arms 5. While the steam is being admitted, gas can escape via the steam outlet 7 so that no pressure builds up in the cleaning chamber 3.
  • the third valve 32 is closed during the cleaning process. The introduction of steam through the steam connection 17 and the cleaning fluid introduction device 4 as well as the circulation of the cleaning fluid and the exposure of the goods 2 to the cleaning fluid can be carried out and repeated alternately.
