Definitions
- the invention relates to a method for the preparation of fruits, berries and / or vegetable noses for the production of liquid raw products by comminuting the roma material and separating juice porridge.
- juice porridge pulp juice
- passing machines For the production of juice porridge (pulpy juice) as a preliminary stage for further refinement measures, it is known to use so-called passing machines.
- the juice pulp which consists of juice and cell material, is separated from the seeds, stems, shells and core casings by mechanical action.
- the invention has for its object to provide a method with associated plant for the extraction of juice porridge, which ensures improved quality of the juice porridge with high economy and reduced investment costs.
- this object is achieved in that juice pulp consisting of juice and cell material is obtained by pressing the comminuted raw material. Further advantageous and expedient refinements of the invention can be found in the patent claims.
- the advantages achieved with the invention consist in particular in that the gentle handling of the raw material during pressing means that stems, cores and shell parts of the fruit are not ground and injured. This results in an improvement in the quality of the juice porridge. Due to the coarse mesh size of the press according to the invention and the special design of the separating and screen surfaces, fine pulp and cell material are removed with the juice pulp. There is therefore less particulate matter and cell material in the residue, which favors the economical use of a recycling press to increase the yield.
- the preferably conventional press functioning as a recycling press is thus relieved of a great deal of pressure by the press according to the invention. As a result, the requirements for the recycling press are less high, so that it can be built cheaper and the investment costs are reduced.
- Horizontal basket presses are particularly suitable as recycling presses because of the long flow paths that are necessary for the recovery of retentate from cross-flow filtration.
- the yield is increased since, in addition to the juice, more or less whole cells with the enclosed juice are squeezed out.
- the construction of the press according to the invention can be made very simple and cost-saving due to the lower requirements, for example larger passage openings, compared to conventional juice presses.
- Fig. 3 is a schematic side view of a belt press for the extraction of juice porridge
- Fig. 4 shows a section through the belt press along the line IV-IV in Figure 3 in an enlarged view.
- the raw material to be processed is introduced and crushed in the form of whole fruits in a comminution device 1, which can be a mill, for example.
- the mash obtained in this way is preferably treated with known mash enzymes so that the individual cells separate better from the cell structure.
- the treated mash is then fed to a press 2 and pressed out.
- the press 2 is a press system specially developed for the extraction of juice porridge, which guarantees extremely gentle processing of the shredded raw material. The specific design features of the press 2 will be explained later.
- the juice pulp obtained which consists of a pulpy liquid mass of juice and cell material, is fed from the press 2 to a refining device 3.
- the juice pulp is further processed to pulpy juices, clear juice by filtration, dry products by drying, substrates to bioreactors, wine, etc.
- the residue remaining in the press 2 is pressed out again to improve the yield in a recycling press 4 assigned to the press 2.
- the juice obtained is introduced into the juice pulp via a line 5 to the press 2.
- FIG. 2 Another embodiment of the invention is shown in FIG. 2.
- the raw material is comminuted in the comminution device 1 and fed to the press 2.
- pectolytic enzymes are added to the raw material in dosed quantities before comminution.
- the one in the press 2 from the shredded.
- Juice pulp of juice and cell material separated from raw material is fed via line 6 to a crossflow filtration device 7, which consists of an ultra or microfiltration system, and processed into clear juice.
- a treatment stage 8 is arranged in the line 6 between the press 2 and the crossflow filtration device 7, in which the juice pulp is treated in a known manner with juice enzymes.
- the enzyme treatment causes a reduction in the viscosity of the juice porridge and thus an improvement in the filtering performance in the subsequent crossflow filtration device 7.
- the juice porridge can be further liquefied by means of various liquefaction techniques, for example by enzymatic, chemical or physical cell disruption before it is fed to the cross-flow filtration device 7.
- the residue from the press 2 is introduced into the recycling press 4 and pressed out.
- the juice obtained is introduced via line 5 between treatment stage 8 and cross-flow filtration device 7 into line 6 or into the juice pulp.
- the juice porridge is then processed into clear juice in the crossflow filtration device 7.
- a line 9 leads from the crossflow filtration device 7 to the recycling press 4 in order to mix the retentate from the crossflow filtration for further use in the recycling press 4 with the residue of the press 2 to be pressed out. It is expedient to arrange a pre-treatment stage 10 for the retentate in line 9 between crossflow filtration device 7 and recycling press 4. In the pretreatment stage 10, the retentate is treated in a known manner with cellulase and fining agents, before it is introduced into the recycling press 4.
- a further line 11 is branched off from line 6, which e.g. feeds a colloid mill 12.
- the juice porridge is processed in a known manner to pulpy juice and then mixed with the juice of the recycling press 4 by branching off a line 13 from the line 5.
- a press belt 15 runs approximately horizontally from a drive drum 14 to a press drum 16 and is guided around the press drum 16 with a wrap angle of approximately 280 °.
- the press belt 15 is returned to the drive drum 14 via a deflection roller 17 leads.
- the comminuted raw material to be pressed is introduced on the inside of the horizontal section of the press belt 15 into the gap between the press belt and the outer surface of the press drum 16.
- a press layer 18 of the raw material is formed, the thickness d of which is approximately 3-20 mm.
- the press layer 18 is relatively thin compared to conventional belt presses, in which the press layer thickness is approximately 30 to 50 mm, so that short juice paths are created which allow the highest possible proportion of viscous cell material next to the juice. In conjunction with the large wrap angle ⁇ of at least 250 °, the press has a high specific effect in terms of performance and yield.
- the press belt 15 is designed as a sieve belt and forms a partition 19, which is provided with openings 20 through which the juice pulp can flow and is separated from the residue.
- the juice pulp obtained is collected in a trough 21 arranged below the press.
- the pressing residue, which leaves the press drum 16 in the region of the deflection roller 17, is picked up and removed by a transport screw 22 arranged below the deflection roller 17.
- the partition 19 can also be formed by the wall of the press drum 16. In this case, the press belt 15 can be closed and the openings 20 can be arranged in the wall of the press drum 16.
- the openings 20 in the dividing wall 19 or in the press belt 15 are made relatively large in comparison to conventional belt presses and widened in the pressing direction, so that the viscous juice pulp can pass through easily.
- the gap is preferably Width w of the openings 20, in particular when processing pome fruit, is approximately 1.5 to 3 mm, while conventional belt presses have a gap width of only approximately 0.5 mm.
- the thickness S of the partition wall 19 or the press belt 15 is relatively thin-walled with 0.4 to 1 mm compared to the known presses, while it is approximately 2 mm in conventional belt presses.
- a particularly effective and advantageous choice for the thickness d of the press layer 18, the gap width w of the openings 20 and the thickness S of the partition 19 has been found to be a size ratio in which the press layer thickness d is less than times the gap width w and the gap width w is more than 3 times the thickness S of the partition 19.
- the method and the system according to the invention can also be used to advantage for the processing of various raw materials from agricultural products and waste into substrates for biotechnological processes.
