Principle

◆ The feed liquid is added to the upper part of the heater of the falling film evaporator through the feeding pump, evenly distributed by the film distribution device, and flows downward in a film like manner along the inner wall of the heat exchanger shell. The water evaporates rapidly, and the vapor and liquid are fully separated by the separation device. After condensation, the residual heat of the secondary steam can enter the rear or front channel for further heating, and the liquid phase is discharged from the separation chamber. It can also be used in combination with multi effect, forced circulation, MVR, solidification and other evaporators.

Application scope

◆ Suitable for continuous evaporation, concentration, and crystallization in industries such as milk, juice, biochemistry, pharmaceuticals, seasonings, food additives, and industrial wastewater.

Main features 

◆ The machine has the characteristics of high heat transfer efficiency, small temperature difference, low installed power, large processing capacity, and short heat exposure time.

◆ The evaporation temperature is relatively low, and the efficiency and evaporation temperature can be selected according to customer requirements.

◆ The unique top spray film distribution device of the heating evaporator ensures uniform film formation.

◆ The condenser has a unique structure, high heat transfer coefficient, and good performance.

◆ Adopting a jet hot press pump, the energy-saving effect is significant.

◆ Both automatic control and manual control models can be used according to user requirements.
