Scraper evaporator concentrate

■ the unit by the scraper device., condenser, evaporator, gas-liquid separator, liquid tank. The vacuum buffer tank and concentrate tank. Vacuum pump. Hot oil pump and fuel tank of thermal conductivity and electrical control box. Scraper evaporator is a rotating scraper will distribute the material evenly into thin film shape. Can be falling film evaporation under vacuum conditions in high efficiency evaporator. Its heat transfer coefficient, evaporation intensity is high, the flow time is short and large elasticity of operation. Especially suitable for heat-sensitive, crystallization of high viscosity material and material including particle evaporation concentration, degassing, distillation purification. Therefore widely used in pharmaceutical, chemical, food, petroleum, yue, pesticides and other industries.
 

Performance and features
■  scraper evaporator using centrifugal rotor of the sliding groove. Is the new evaporator structure at home and abroad. Under the condition of the flow is very small also can form the membrane. On the inner wall of the cylinder in evaporation processing adhered on the surface of the liquid in the warp can be scraper quickly. Compared with fixed clearance scraper evaporator. Evaporation can increase 40-69%. It has the following properties and features:
1, high coefficient of heat transfer value. Large evaporation capacity. Evaporation strength can reach 200 kg/m2hr, high thermal efficiency.
2 short heating time, material. About five seconds to 10 seconds. And work in the vacuum conditions. More advantageous for heat-sensitive materials. Keep all kinds of ingredients do not produce the decomposable. Ensure the product quality.
3, to adapt to changes in viscosity range. Both high and low viscosity can be processing. Material viscosity can be as high as 100000 centipoise (CP)
4, change the scraper groove direction of rotation. Can adjust the concentration of the material in the evaporator of time and material.
5, simplified the lining in evaporation through fine boring and polishing processing. The surface is not easy to produce coking, scaling.
6, easy to operate. The product indicators to adjust easily. Under the condition of closed. Can control for continuous production.
7, the structure of the equipment cover an area of an area small. Simple. Easy maintenance.
