Function of vacuum extraction and concentration equipment in the production of concentrated fruit and vegetable juice

Vacuum extraction and concentration equipment is one of the main equipment to produce concentrated fruit and vegetable juice, condensed milk and milk powder Vacuum concentration is to use vacuum concentration equipment to make water in fruit and vegetable juice and milk rapidly develop under reduced pressure with low Ju, so as to continuously improve the concentration of the product The direct pump can meet the concentration requirements Extraction and concentration equipment is widely used in food, medicine, chemical industry and other industrial sectors Some of the food materials such as fruit and vegetable juice and milk were removed by vacuum concentration, which reduced the weight and volume, kept the original flavor and nutritional value of the materials, was conducive to the preservation and transportation of the products, and improved the quality of the products The particles of milk powder and juice powder produced after concentration are larger, which is conducive to the recovery of dust and improves the yield of products The concentration equipment mainly includes vacuum extraction and concentration equipment, freeze concentration equipment and reverse osmosis concentration equipment The vacuum concentration equipment adopts the method of vacuum Yanfa or mechanical separation to concentrate the material At present, vacuum Yanfa is mostly used, which has the following advantages: (I) vacuum evaporation reduces the boiling point of the material, accelerates the Yanfa of water, avoids the high temperature treatment of the material, and is conducive to the preservation of the nutrient composition of the material, (2) It improves the Ju degree difference between heating Yanqi and materials, speeds up the concentration process and improves the production capacity (3) Low pressure steam can be used as heating steam to reduce heat loss of equipment (4) In the reduced limit state, the material can be absorbed into the concentration equipment by itself, and the feed pump is omitted In addition, it has certain heating sterilization effect
