Fruit and vegetable juice three-extraction new process

Abstract

The invention discloses a fruit and vegetable juice three-extraction new process and relates to the field of processing industry of fruit and vegetable juice. A squeezing process is as follows: 1) on the basis of keeping the original squeezing process unchanged, the third squeezing is increased on the flow process of the first squeezing and the second squeezing; 2) raw juice obtained by adding water into fruit and vegetable residues after the second squeezing for dissolving the fruit and vegetable residues is taken as a raw material for the third squeezing; 3) the water adding quantity for the fruit and vegetable residues after the second squeezing is appropriately regulated according to the content of the raw juice in the fruit and vegetable residues after the third squeezing so as to enable the content of the raw juice in the fruit and vegetable residues after the third squeezing to achieve the requirements. According to the new process disclosed by the invention, the concentration of fruit juice can be effectively improved by increasing the third squeezing on the basis of the original processing process and recycling the raw juice of the third squeezing, the consumption of multiple items, namely water energy, electric energy, time and the like can be further reduced, the loss of the raw material can be reduced, the production energy consumption can be reduced, and the production benefits can be improved.

Description

1. Technical field: [0001] The invention relates to the field of fruit and vegetable juice processing industry, in particular to a new technology for triple-pressing and extracting fruit and vegetable residues. 2. Background technology: [0002] With the deepening of the concept of health, more and more consumers are paying more attention to health, giving up carbonated drinks and turning to juice drinks. However, the U.S. fruit juice beverage market is growing slowly, and the growth rate of the European market is also stable, showing no upward trend. If you want to achieve a breakthrough in sales in mature markets, the focus will naturally turn to new product development. New products need to be different, taste good, and meet people's health needs. Pure fruit juice (100% original juice) has grown significantly, and many manufacturers are also focusing on energy and luxury soft drinks. [0003] At present, domestic fruit and vegetable juice processing enterprises general...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic fruit and vegetable juice processing enterprises generally use two squeezes to extract juice from raw materials, instead of three squeezes, so that nearly 10-20% of the original juice remains in the fruit and vegetable dregs after the second squeeze and is discarded. A large amount of water needs to be added in the process to make the sugar concentration of freshly squeezed juice lower, and the energy consumption of electricity and coal in the process of juice concentration is relatively high
