Fruit and vegetable processing is processed through various processing techniques so that fruits and vegetables can be preserved for a long time, not bad for a long time, and ready for use at any time. In the processing and processing, it is necessary to preserve its nutrient composition to a large extent, improve the edible value, make the processed products have good color, fragrance, and taste, and the organizational form is more and more, and further improve the commercialization level of processed fruits and vegetables.

The fruit processing process of gf-machine , Fruit Processing Machine mainly includes:

1. Take the juice. The method varies depending on the species. The juices of apples and grapes are contained in the whole fruit, and the juice is usually taken by crushing and pressing method; the citrus has the outer skin, and the juice is present in the juice cells, and the juice is commonly used in the juice machine. The juice yield of various fruits is generally 45-80% of the fruit weight.

2. Clarify filtration. Removal of suspended solids and colloidal particles from juice is an important step in making clear juices. Commonly used are gelatin-tannin, heating coacervation, and enzyme preparation.

3. Homogenization and degassing. Dedicated to the production of turbid juice. Homogenization is the mechanical action to disperse suspended particles in juice to enhance its stability. High-pressure homogenization requires a pressure of 150 to 170 kg/cm2. Degassing or deaeration is the process of removing air from turbid juices, avoiding oxidative discoloration of fruits, loss of vitamins, corrosion of tinplate on the wall of the tank, and elimination of foam. It is usually carried out by the vacuum method. Volatile flavors that are lost during degassing can be recovered.

4. Packaging and sterilization. Cans are generally used as containers. Sterilize with pasteurization. The sterilization condition of the transparent juice is usually 80 ° C, 30 seconds, and the turbid juice is 90 to 95 ° C, 30 to 60 seconds. In addition, the fashion of concentrated juice needs to use a vacuum to remove part of the water to increase the juice concentration. The juice powder is desalted by spray drying.
