Embodiment 1

[0031] A treatment method for the retentate produced in the film clarification process of apple juice production:

[0032] (1) Mix the retentate produced during the film clarification process of apple juice production with diatomaceous earth; wherein the content of insoluble solids in the retentate is 36%, and the amount of diatomite added accounts for 0.25% of the total mass of the retentate ;

[0033] (2) Inject the mixture of the retentate and diatomaceous earth into a closed external pressure membrane filter press device for pressure filtration treatment, and control the working pressure of the filter press device at 0.45~0.5MPa to obtain liquid-phase clear juice and solid pomace;

[0034] (3) After the pressure filtration, the collected liquid-phase clear juice was directly mixed with the clarified apple juice product, the recovery rate of the residual apple juice in the retentate was 99%, and the light transmittance of the liquid-phase clear juice (T 625nm ) up to 98%, ...

Embodiment 2

[0037] A processing method for the retentate produced in the film clarification process of pineapple juice production:

[0038] (1) The retentate produced in the film clarification process of pineapple juice production is mixed evenly with perlite; wherein the content of insoluble solids in the retentate is 28%, and the addition of perlite accounts for 0.12% of the total mass of the retentate;

[0039] (2) Inject the mixture of retentate and perlite into a closed external pressure membrane filter press device for press filtration treatment, and control the working pressure of the filter press device at 0.45~0.5MPa to obtain liquid-phase clear juice and solid pomace;

[0040] (3) After the pressure filtration is finished, the collected liquid phase clear juice is directly mixed with the pineapple juice product, the recovery rate of pineapple juice remaining in the retentate reaches 99%, and the light transmittance of the liquid phase clear juice (T 625nm ) up to 96%, turbidity ...

Embodiment 3

[0043] A kind of processing method of the retentate produced in the film clarification process of jujube juice production:

[0044] (1) Mix the retentate produced in the film clarification process of jujube juice with activated carbon evenly; wherein the content of insoluble solids in the retentate is 42%, and the addition of activated carbon accounts for 0.36% of the total mass of the retentate;

[0045] (2) Inject the mixture of retentate and activated carbon into a closed external pressure membrane filter press device for pressure filtration treatment, and control the working pressure of the filter press device at 0.5~0.55MPa to obtain liquid-phase clear juice and solid pomace;

[0046] (3) After the pressure filtration, the collected liquid-phase clear juice was directly mixed with the jujube juice product, the recovery rate of the jujube juice remaining in the retentate was 99%, and the light transmittance of the liquid-phase clear juice (T 625nm ) up to 95%, turbidity <3...

Abstract

The invention relates to a method for processing retentate generated in film clarification process of fruit-vegetable juice production. The method comprises the following steps: mixing the retentate generated in film clarification process of fruit-vegetable juice production with a filter aid, injecting the mixture into an airtight external-pressure type film filter press, and carrying out filter pressing, so as to obtain liquid-phase clear juice and a solid-state fruit residue, wherein the liquid-phase clear juice can be used for producing fruit-vegetable juice products, thereby increasing the product yield, and the solid-state fruit residue is a solid substance which cannot flow, has the water content less than 25% and can be processed in a concentrative dumping manner or converted into animal foods. According to the method, the technical problem that the loss and the wastage are serious because the retentate generated in the film clarification process of fruit-vegetable juice production is difficult to process, solid and liquid phases are not thoroughly separated and the fruit-vegetable juice in the retentate cannot be adequately extracted is solved.

Description

technical field [0001] The invention belongs to the field of agricultural product processing, and in particular relates to a method for treating the retentate produced in the film clarification process of fruit and vegetable juice production. Background technique [0002] In the fruit and vegetable juice processing and pharmaceutical industries, cross-flow filtration methods such as ultrafiltration are commonly used to intercept insoluble substances and macromolecular substances in fruit and vegetable juices or fermentation liquids, so as to ensure the quality requirements of the clarification treatment of fruit and vegetable juices and pharmaceutical fermentation liquids. However, with the continuous increase of the concentration of insoluble matter in the cross-flow filtration circulating liquid, the flux of the filtration system gradually decreases. When the retained insoluble matter content reaches 20-60%, it is very easy to block the membrane channel. The current cross-f...
