The three effect evaporator is mainly composed of three tube heaters, three evaporation chambers, a circulation tube, a condenser, a liquid receiving tank, and other ancillary equipment. The three effect evaporator is widely suitable for the concentration of liquids such as traditional Chinese medicine, Western medicine, glucose, starch, monosodium glutamate, dairy products, and chemical products, especially for low-temperature vacuum concentration of thermosensitive materials.

The maintenance instructions for the three effect evaporator are as follows:

1. Replace the lubricating oil within one month of use, and replace the lubricating oil every 3-4 months thereafter.

2. Open the bottom bearing every two months, check the wear of the bottom bearing, and replace it if necessary.

3. Add sealing fluid to the mechanical seal chamber once a month, using 20 # mechanical oil as the sealing fluid.

4. According to the properties of the material, the inner cylinder should be regularly soaked and cleaned with warm water or solvent.

5. After opening the low head, unscrew the bolt at the bottom of the rotor U-shaped groove and replace the scraper every four months.
