Definitions

  • the invention relates to a method and a system for clarifying raw juice from fruit, grapes, berries or other fruits and vegetables or wine and beer by means of pre-washing and cross-flow filtration.
  • the pre-finishing of juices by adding fining agents all substances causing cloudiness should be removed so far that night cloudiness no longer occurs at a later point in time.
  • the pretreatment is intended to improve the sensory properties of the juice and possibly also lighten the color.
  • the performance of cross-flow filtration is to be significantly improved.
  • a method is known with a continuous pretreatment and a semi-continuous as well as continuous 1-stage cross-flow filtration.
  • a filter press is provided in the retentate circuit of the cross-flow filtration system with which the turbidity is removed from the cross-flow filtration system.
  • the filtrate from the filter press is fed into a buffer tank of the crossflow filtration system or. returned to the feed line of the crossflow filtration. Due to the use of a filter press for permanent trub separation from the retentate circuit of the cross-flow filtration system, the operating mode semi-continuously or 1-stage-continuously has a significantly smaller influence on the behavior of the cross-flow filtration system, especially the service life until cleaning.
  • the cross flow filtration system works with capillary modules respectively. Thin channel modules.
  • the known plant is intended for the clarification of wine.
  • a disadvantage of this known embodiment is that the outlay for the slurry removal device is very high. In the case of semi-continuous systems, further investment costs arise through the use of a buffer or batch tank, which also greatly increases the effort for a fully automatic system. In addition, the flux, that is to say the throughput of the cross-flow filtration system, remains relatively low, which increases the cost of operating the system.
  • the thin-channel capillary modules of the cross-flow filtration system do not allow a high concentration factor.
  • the invention is based on the object of avoiding the disadvantages mentioned and of creating a method of the type mentioned at the outset which increases the profitability of the system, facilitates the automation of the process sequence and improves the product quality.
  • this object is achieved by the indirect or direct combination of at least partially continuous pretreatment with a least 1-stage, continuous cross-flow filtration system, which with a relatively high solids content in the retentate or. a high concentration factor is operated.

  • the clarified juice is discharged as a permeate via a line 11.
  • the cross-flow filtration system 3 is equipped with large-channel modules which have a channel gap width or, in the case of tubular modules, a channel diameter of at least 4 mm. This results in a relatively high proportion of solids. a high concentration factor in the retentate circuit 8 of the crossflow filtration system 3.
  • the wet turbidity content of the retentate stream is at least 40% and the concentration factor based on apple juice from the horizontal basket press is at least 20%.
  • there is also an additional trub load which is the Schönunsgtrub.
  • the cross-flow filtration system 3 is operated warm at a temperature of at least 30 ° C. This measure also contributes to a significant increase in flux.
  • the continuous pretreatment can also be carried out, for example, using the known flotation process.
  • the raw juice in the pretreatment 1 is mixed with various fining agents, which are supplied via the lines 5, 6, 7 in metered, controllable amounts.
  • the flocked-out fining slurry is continuously discharged from the pre-fining 1 through line 13. In this case, care must be taken to ensure that the concentration factor in the subsequent cross-flow filtration system 3 is increased rapidly in order to prevent pore blockages or. to avoid irreversible flux reduction.
  • the combined method according to the invention has the advantage over clarification, which is carried out exclusively by flotation, that fewer fining agents are required with a better brilliance of the clear juice.
  • the flotation system can be dimensioned much smaller in this case, since it is only pretreated.

If pre-centrifugation is carried out before the pretreatment, the trub ejection produced by the centrifuge 15 can be introduced via a line 16 into the retentate circuit 8 of the continuously operating crossflow filtration system 3 to improve the overall yield. As can be seen from FIG. 1, an aroma recovery system 17 can be connected upstream of the continuous pretreatment 1.

Abstract

Le procédé pour la clarification de jus brut de fruits, raisins, baies ou autres fruits et légumes, ou bien de vin ou bière, est réalisé par la combinaison de pré-clarification continue (1) avec une installation de filtration à courant transversal à 1 étage (3), laquelle travaille en continu. L'installation de filtration à courant transversal (3) fonctionne avec une proportion relativement élevée de matières solides dans le circuit de rétentat (8) ou avec un facteur de concentration élevé. Ceci permet d'obtenir une augmentation considérable du rendement de l'installation ainsi que des économies respectives dans les coûts d'investissement et d'exploitation.
