Introduction
Ethanol is the most commonly used organic solvent in the natural plant extraction because of its excellent solubility. However, to get an actual effective product, users need to remove ethanol from the crude product after extraction. Falling film evaporator is one of the most effective device.
Its main structure is as following:
It is composed with evaporator, evaporation chamber, separator, condenser, liquid receiver, pump units, water ring vacuum system, anti-explosion type electrical control system, etc.
The equipment is continuously operated under vacuum and low temperature conditions. It has advantages like high evaporation capacity, energy saving and low consumption, low operating cost, and is able to ensure the invariance of materials during the evaporation process.
Feature
1) Optimized design after a lot of practical experience;
2) Enough heating exchanging area and cooling heat exchanging area to keep good performance;
3) Even the pilot size are equipped with insulation on evaporation chambers and evaporators;
4) Motor and electric control cabinet are anti-explosion type;
5) Multiple ways of heating, steam or conductive oil;
6) SS304 or SS316 material, satisfying GMP standard.
