Definitions
- the invention relates to a method and a device for automated, industrial examination and / or classification of foods, in particular meat or other foods. Likewise, the invention relates to foods or food fractions produced or obtained accordingly.
- WO 97/26533 discloses determining the ratio of lean to fat portions in pieces of meat by means of microwave spectrometry.
- US Pat. No. 5,428,657 describes using Rayleigh and Compton scattering of X-rays to remove unwanted pieces of material in, for example, bone-free pork according to Art and location to detect.
- WO 00/21376 it is known from WO 00/21376 to cut pieces of meat into cubes, to record them with optical recording devices and then to separate them.
- a disadvantage of the known methods is that it is often not possible to differentiate with regard to the most varied constituents or the measurements cannot be carried out continuously over large areas of the food.
- the term foods includes nutrients or nutrients and foods and / or their constituents, in the case of meat e.g. To understand connective tissue and / or connective tissue-containing mixture, as well as their mixtures.
- the term “food” is furthermore to be understood as a single food or a plurality of foods, which in the latter case are processed together.
- the term food not only includes food, but also animal feed.
- meat of various preparation and comminution stages can be considered as foodstuffs.
- foodstuffs include, for example, cereal grains, rice, coffee, vegetable fruits (e.g. peas) or a mixture of, for example, bread, dough, yogurt or similar mixtures of different foods.
- White light is preferably radiated onto the foodstuffs.
- Photodectors are advantageously used as color sensors, which are preceded by filters with transmission sensitivities, for example in the red, green or blue spectral range.
- the filters are regarded as part of the sensors.
- the color filter or filters each have their own transmission characteristics.
- the recorded reflection spectra are therefore evaluated with the respective filter characteristic in the respective pass band.
- the curves in this spectral range are, at best, characteristic of certain meat components.
- the measuring range is advantageously between 190 nm and 2400 nm and in a preferred embodiment between 400 nm and 700 nm. Wavelengths smaller than 400 nm are also possible (UV or near UV range).
- Such a sensor arrangement which takes advantage of the reflection spectra evaluated with the aid of the color filter characteristic mentioned above, allows tissue types or tissue compositions of pieces of meat to be precisely recognized, for example.
- the recorded overall spectra can be correlated with the individual color sensor characteristics in order to obtain a partial spectrum, in particular evaluated on the basis of the color filter characteristics, for each of the color sensors. Alternatively, no overall spectra are recorded over a larger spectral range, but only partial spectra with the different color sensors.
- each sensor integrally detects the signal intensity in its respective spectral range, i.e. the area under the trace of each color sensor.
- the differentiation between the different food components is best if the components to be examined have their own spectral characteristics in each spectral range measured. However, the differentiability in a single spectral range can also be sufficient for a reliable determination.
- the foodstuffs to be examined are preferably pressed directly against a glass surface made of quartz or another material, behind which the light source and the color sensors are arranged. In this way, unwanted influences of light refraction on ambient gases or liquids, absorptions etc. can be avoided. turn off.
- the light to be irradiated can also be directed in the form of a scanning beam onto the food to be measured.
- a special measuring technique for the evaluation of the reflections or reflection spectra also allows integral measurements.
- the spatial resolution in the measurements is expediently chosen to be large, e.g. also to record small accumulations of risk material. It is advisable to adapt the speed of the flow of food through the measuring section to the measuring conditions accordingly. If the foodstuffs have to remain in the measuring section for a certain time, for example a few seconds, they can also be conveyed quasi-continuously, i.e. with a short break.
- the measuring section can be either open or closed.
- the measurements can be carried out on a conveyor belt or in a measuring chamber. If a closed measuring chamber is used, the food can fill it completely to exclude the presence of gases and / or liquids.
- the foodstuffs are compressed, for example, and in particular gas is pressed outwards from interspaces, the is then preferably suctioned off. The compression or the pushing together of the food naturally depends on its consistency.
- the certainty of determination can be increased by combination with measurements and analyzes using the hitherto usual methods, but also by means of new so-called in-line analysis methods, these using, for example, microwaves, X-rays, ultrasound, magnetic resonance, electron magnetic resonance or other suitable ones Technology based. Inductive, conductive and capacitive measuring methods can also be used with advantage. Alternatively, other suitable physical, chemical and / or biochemical measuring and analysis methods can be used, which can be used in the method according to the invention for analysis and for in-line scanning and thus in particular for the control and secretion of undesired product components.
- the measurements of the reflection spectra are combined with ultrasound measurements or conductivity or resistance measurements in order to be able to compensate for any inaccuracies in the respective other measurement method.
- Conductive or conductivity measurements or inductive measurements are particularly able to provide information about moisture content and moisture distribution, in particular of water, in and around the food.
- the measurements are not carried out on the complete product stream, but only on a part branched off from this main stream.
- These so-called bypass measurements are used less for sorting individual food components, but rather for an approximate determination of percentages in the food, for example fat and lean meat in mixed and minced meat.
- the at least one conveying device preferably takes on both the transport of this expediently relatively small portion of food to the measuring section and the conveying of the main flow.
- a screw conveyor that begins in front of the branch leading to the measuring section and leads past the branch can push part of the food into this side arm up to the measuring section.
- one or more valves can be arranged in front of the measurement section.
- the conveyor prefferably feeds into a mixing section - e.g. a mixing chamber - from which the partial product stream to be measured e.g. is branched off into a separate measuring section by means of a suction piston.
- the partial product stream is introduced again into the mixing section or into a conveying section adjoining this, and mixed with the main product stream. This procedure also represents a bypass measurement.
- a suction piston By means of a suction piston, a similar suction device or another conveying device, only a part of the food from the mixing chamber (or also a comminution chamber) can be sucked into a measuring chamber or be conveyed into it in some other way, whereupon this portion is subsequently measured and opened again same way is pressed back into the mixing chamber or the comminution chamber.
- the measuring unit can also be arranged directly on a housing of a mixing plant or a comminution device, for example a cutter, in order to radiate light onto the foodstuffs contained therein and to measure their reflection spectra.
- the housing or container wall of the mixing plant or the comminution device preferably has a glass window made of quartz or another suitable material through which the incident and preferably also the reflected light rays pass.
- the glass window can also be arranged in the bottom of the container.
- the container can be rotatable. Alternatively or additionally, the mixing or cutting tools rotate in the container.
- the measured values - if necessary after suitable signal or data processing, in particular analog-to-digital conversion - are preferably obtained from a computer using suitable algorithms with reference values or reference curves compared, which were previously stored in an electronic memory.
- reflection measurement values can be obtained, for example, when measuring individual meat or food components using UV light and visible light were obtained, are compared with target values which correspond to the reflection of a meat fraction with a predetermined proportion of a certain histological component (eg nerve tissue).
- the computer can then give an actuator the command based on the detected deviations, for example to eject contaminated material after the measuring section via an ejection opening. Normal or unproblematic material can be continued on the normal funding route. In this way, undesired product fractions can be separated out specifically and safely with the help of separation units - such as the ejection opening mentioned.
- the at least one conveyor which preferably conveys the food continuously, is expediently adapted to the special requirements.
- a screw conveyor can be used for this.
- a vacuum conveyor is used.
- a pump device which is designed, for example, as a vane cell delivery device. This can be used individually or in combination with at least one other suitable conveying device, for example a vacuum conveying device.
- Any other suitable conveyor device for transporting the product at least in sections into the measuring section can also be used, for example a suction device, a vibrating device or a conveyor belt.
- foods lying on a conveyor belt can advantageously be transported to the measuring section and measured there.
- the local be stored in containers, such as boxes, to transport the container to the measuring section.
- the foodstuffs are conveyed in tubes and measured either in the tubes or in a special measuring chamber (in the main stream or in a bypass or in a measuring room with delivery and removal in the same way).
- the measuring unit can be designed in such a way that it can be moved back and forth above or below the material to be measured, for example in the form of a portal, in order in this way to scan or measure the foodstuffs which are then expediently stationary or also moving.
- the measuring unit is stationary and the food is conveyed continuously or discontinuously.
- the measuring unit can advantageously be designed to be adjustable in height and / or in inclination.
- One or more sorts are preferably carried out in different parallel and / or successive production steps.
- the method according to the invention and the device according to the invention in their various configurations can in each case be used here — if appropriate with suitable modifications according to the respective size and / or consistency and / or composition of the foodstuffs of the individual production stages.
- one or more predetermined physical, chemical and / or biochemical variables are preferably measured, analyzed and advantageously sorted out or assigned in different production levels in order to obtain the desired end fractions.
- this can be done in that after the larger pieces of meat have been cut into slices in further process stages, for example, the ejected and, if necessary, shredded pieces of meat are conditioned (ie isolated) in a flow-freezer and a channel running vertically. a trough, a conveyor belt or other conveying device are fed through which the pieces of meat pass one after the other or are conveyed by this.
- At least one measured variable of the pieces of meat is advantageously measured and a sorting device - for example a blow-out nozzle - is given the command via a control unit to output the corresponding pieces of meat if the threshold value is exceeded or fallen below to remove the guide device or fall line, for example to blow it out.
- a sorting device for example a blow-out nozzle - is given the command via a control unit to output the corresponding pieces of meat if the threshold value is exceeded or fallen below to remove the guide device or fall line, for example to blow it out.
- the mixed meat fractions sorted out in the preceding stages described above - consisting, for example, of lean meat, fat and connective tissue - are further processed.
- an additional sieve-press process step a further separation into largely pure-tissue lean meat pellets and fat pellets as well as possibly smaller connective tissue particles is used.
- larger pieces of connective tissue are advantageously removed before the subsequent sorting step and the remaining pieces of meat are sorted into a first fraction with almost exclusively lean meat pellets and a second fraction with almost exclusively fat pellets, and possibly into a third fraction with risk material.
- an in-line scanning can advantageously be followed using the reflection spectrum measurements according to the invention for controlling the recipes via the sorting device.
- a gravimetric measuring method i.e. Gravity screening processes can be used.
- the measuring method according to the invention can be used with advantage, for example, when meat is cut into cubes and these are measured on a conveyor belt using the method according to the invention and sorted into a lean or fat fraction and another mixed fraction according to predetermined parameters.
- the mixed fraction can then be further separated into a fraction with almost exclusively lean meat particles and a second fraction with almost exclusively fat particles and separately separated hard connective tissue particles and / or risk material particles in this additional process stage of the method according to the invention.
- the fat tissue and / or connective tissue particles sorted out in the previous process steps can be separated into a fraction consisting essentially of proteins (with possible fat fractions) and a fraction consisting essentially of fat (with possible protein fractions) in a known manner become.
- the above-described aspects of the invention and the associated special embodiments can be combined to form several successive process stages, so that, for example, the slice-like products mentioned after being cut in a cube cutter or the particles which have already been cut in the meat grinder are optically sighted and mixed fractions subsequently this sorting experience a further sorting. This can be done by means of a screen press device and subsequent optical or gravity sorting, as well as a subsequent fat separation in a volatile solvent
