What are the main characteristics of single effect external circulation vacuum concentrator

The single effect external circulation vacuum concentrator is suitable for the recovery of industrial organic solvents (such as alcohol) such as traditional Chinese medicine, western medicine, glucose, wine making, starch, oral liquid, food, chemical industry, etc it is also suitable for the low temperature vacuum concentration of many kinds of heat sensitive materials The main characteristics of the single effect external circulation vacuum concentrator are as follows: 1 The whole heating system of the equipment has the main characteristics of high heat transfer efficiency and short heating time due to the uniform steam heating and liquid film flow evaporation For example, it has the advantages of energy saving, low steam consumption and low cooling water circulation 2 The material flows downward along the inner wall of the pipe to accelerate the pressure flow evaporation, which is suitable for the evaporation and concentration of the material liquid with high viscosity 3 Because the material evaporates in the form of film in each tube, the heating time of the material liquid is very short, so it is very beneficial to the evaporation and concentration of food, and it can greatly preserve the nutritional ingredients of food
4 Under the action of vacuum, the evaporation process not only ensures the hygiene requirements of materials, but also ensures the environmental protection requirements At the same time, it greatly reduces the evaporation temperature In addition, it is equipped with a hot press pump Part of the secondary steam is re inhaled by the hot press pump and mixed with the raw steam, which saves the raw steam At the same time, because the steam passing through the hot press pump enters the heating shell in the form of spray mist, the steam diffuses rapidly, It is suitable for the concentration of heat sensitive materials due to its mild heating 5 the equipment is suitable for vaporizing and concentrating the foaming material As the material liquid evaporates in the heating tube, vapor liquid separation is formed, and at the bottom of the effective part, the bulk of the liquid is removed Only a small amount of liquid and all two steam enters the separator to strengthen separation The process of material liquid has not formed too great impact, thus avoiding the formation of foam.
