The formation of negative pressure in the body to reduce the boiling point of water products, so as to achieve concentration, product evaporation temperature of about 60 ℃.
The inside of the body for the arrangement of the thin tube, the tube for the internal product, the external steam, the product from the top down the flow process due to the increase in the area of the tube leaving the product was membrane-like flow to increase the heating area, through the vacuum pump in effect
After the first pass through the body can not achieve the required concentration, the product after leaving the product through the lower part of the effect of the vacuum pump products through the external pipe to the body of the upper body again through the body, and then through this repeated
MVR evaporator is different from the ordinary single effect falling film or multi-effect falling film evaporator, MVR is a single evaporator, set the multi-effect falling film evaporator in one, according to the required product concentration to take sub-type evaporation,
