product description
The three-effect falling film evaporator is suitable for evaporation and concentration of liquid materials in pharmaceutical, glucose, starch, chemical, xylose, biochemical engineering, food and VC industries. The equipment consists of one, two and three effect heaters, one, two and three effect evaporators, preheater, condenser and hot pressure pump. The steam consumption is low, and 1 kg of steam can evaporate 4 kg of water. The evaporating temperature is low, and some of the secondary steam is re-inhaled by the jet type hot-pressure pump, and the heat is fully utilized, and the steaming temperature is relatively low. The concentration ratio is large, and the falling film type evaporates, so that the viscosity of the liquid having a larger viscosity flows, and the concentration time is shorter, and the concentration ratio can reach 1:5.

Double effect falling film evaporator
Applicable fields:
It is suitable for concentrated crystallization of biochemical engineering, petrochemical, pharmaceutical, food and wastewater treatment, inorganic salt and other industries.

Features:
1. It can operate normally at a lower temperature difference between effects and has less heat loss;
2. The material has a short heating time and can be operated under lower temperature conditions, which is suitable for evaporation concentration of heat sensitive materials;
3. It has good applicability to materials with high foaming and high concentration ratio;
4. Since the material is in the tube, it is subjected to the high-speed entrainment of gravity and secondary steam, and is in a membranous turbulent state, so the total heat transfer coefficient is high;
5. The system has less material left in the memory, which can conveniently adjust the residence time of the material in the system;
6, the system can be easily operated under automatic or manual conditions, easy to clean, reliable operation.
