Single-effect falling film evaporator

The single-effect falling film evaporator is suitable for the production of herbal extracts, fruit juices and dairy products.




Structure:
The single-effect falling film evaporator is composed of a heater, an evaporation separation chamber, a partition condenser, a vacuum pump, a condensate pump, a sterilization balance tank, a heat pump, and thermal instruments. The main difference is that the feed liquid is added from the top instead of from the bottom. In order to make the material liquid evenly distributed in each heating tube and flow down its inner wall, a falling film distributor is installed on the top of the heating tube or inside the tube. To make the falling film concentrator operate efficiently, the most critical problem is to make the material liquid evenly distributed in the heating tubes without causing bias flow, so the falling film distributor is installed on the top of the tube or inside the tube.

The material to be concentrated enters the heater from the top, and enters the heating tube evenly under the action of the material-liquid distributor. The material flows naturally downward along the inner wall of the tube in a film-like shape due to the rapid flow of the secondary steam and the action of its own gravity. , And heated continuously to evaporate and concentrate. The concentrated liquid and secondary steam enter the separator for separation, the secondary steam is discharged from the top of the separator, and the concentrated liquid is discharged from the bottom. A key factor for the good operation of the falling film concentration tank is the uniform dispersion of the material on the heating surface. In order to make the material liquid evenly distributed in each heating tube, flow down along the inner wall of the tube, and install a falling film distributor on the top of the tube or in the tube.




Operating procedure:


(1) Turn on the vacuum pump and the condensate drain pump, and input cooling water
(2) Turn on the feed pump to feed the material liquid from the top of the heater. When the material is sprayed from the tangent port of the separator, the heating steam can be turned on, and air compression is required if necessary
(3) When the evaporation starts or after normal operation, turn on the heat pressure pump, and when the concentration reaches the requirement, you can start discharging
(4) Adjust the discharge volume to ensure balance, and adjust the flow rate of raw steam, the flow rate and temperature of cooling water, so that all parameters meet the process requirements.
