Definitions
- the invention relates to a process for the preparation of agricultural products intended as starting material, for example fruits and / or vegetables, for the production of liquid raw products by crushing and selective, enzymatic liquefaction of the starting material and for the subsequent refinement of the liquid raw product.
- the invention is therefore based on the object of avoiding the disadvantages mentioned and of creating a method with an associated system which ensures a higher overall yield at reduced costs and contributes to favoring the consumption of the system and the disposal of the system.
- this object is achieved in that the starting material is liquefied only to such an extent that a liquid-viscous mash paste consisting of further liquefiable coarse portions is formed, which is then fed to a press for the extraction of raw juice.
- the raw juice is expediently clarified by membrane filtration.
- the raw juice can also be refined in a different way, for example by drying to powder or flakes, by adding pulpy fruit juices.
- the retentate residue from the membrane filtration is fed evenly to the mash residue after pressing the mash slurry and then pressed together.
- the resulting juice is fed to membrane filtration.
- the mash porridge is roughly filtered after liquefaction and before pressing.
- part of the fine sludge formed during liquefaction is separated before pressing, which increases the pressing performance.
- the filtrate obtained by the rough prefiltration is distributed to a further stage of the process, for example membrane filtrates, drying, production line for pulpy juices, etc.
- the system for carrying out the method is characterized in that it consists of one or more containers for liquefaction by enzyme treatment, a subsequent fruit juice press and at least one of the finishing stages mentioned.
- a particularly effective solid-liquid separation during the pressing process is achieved if the fruit juice press consists of a horizontal basket press.
- the membrane filtration device expediently consists of an ultra or microfiltration device.
- a coarse pre-filtration device is arranged between the liquefaction container and the fruit juice press.
- the coarse pre-filtration device consists of a gap filter. The latter are advantageously provided with a cleaning device for cleaning the filter surface.
- a pretreatment stage for the retentate returned to the membrane filtration device is arranged between the membrane filtration device and the fruit juice press or the fruit juice press and the membrane filtration device.
- Pretreatment with known fining agents and enzymes prevents the juice from becoming cloudy and improves the filtration of the retentate.
- the resulting raw juice viscosity is significantly lower, for example 20 to 60%, compared to the raw juice extraction using a vibrating sieve or a passing machine. This significantly improves the yield of the subsequent ultrafiltration.
- the pressed residue has a structure which allows the juice contained in the retentate of the subsequent membrane filtration to be recovered in whole or in part in an economical manner. This enables total yields in the range of 94 to 97% to be achieved.
- the pressing residue (pomace) has a relatively low residual moisture of, for example, 42 to 47%, so that it can be dried economically and used for feed purposes, for example.
- the raw material to be juiced which can consist of whole fruits, is crushed in a mill 1 nert and introduced into a liquefaction tank 2 for enzyme treatment.
- the chopped fruits are mixed together with the added enzymes, eg cellulase, pectinase, with the aid of a stirrer and liquefied by the enzymatic treatment.
- the degree of liquefaction of the mash is selected so that a liquid-viscous slurry is formed, which however contains even coarser parts that can be liquefied.
- the state can be achieved in comparison to total liquefaction, for example by reducing the stirring intensity, the liquefaction time (for example 45-75 minutes instead of, for example, 2 hours) and a reduction in the enzyme dosage.
- the quality is further favored by reducing the liquefaction time and the stirring intensity.
- the mash slurry obtained in this way is then fed to a coarse pre-filtration device 3, which operates in a pore or gap size range of approximately 30 to 150 ⁇ m. Because of the risk of clogging, the coarse pre-filtration device
- the retentate from the coarse pre-filtration device 3 is further processed in a fruit juice press 4.
- the raw juice thus obtained is then fed to a membrane filtration device 5 for clarification, which preferably consists of an ultra or microfiltration device. That separated in the coarse pre-filtration device 3. Filtrate is likewise introduced into the membrane filtration device 5 via a line 6 with approx. 10 to 60% of the total flow and subjected to the clarification process, while the retentate of the coarse pre-filtration device 3 is introduced into the fruit juice press 4 with approx. 40 to 90%.
- the retentate residue of the membrane filtration device 5 is fed back into the fruit juice press 4 via a line 7 and mixed with the residue obtained during the raw juice extraction and then filtered. As a result, the juice still contained in the retentate residue of the membrane filtration device 5 is recovered. When it is returned to the fruit juice press 4, the retentate goes through a treatment stage 8.
- Known fining agents such as gelatin, or enzymes, such as pectinase, can be used as treatment agents.
- the system according to the invention can also be used for the preparation of various raw materials from agricultural products and waste for biotechnological processes.
