Description

Technical Field

[0001] The utility model relates to the technical field of concentrating kettle discharging, in particular to a concentrating kettle discharging mechanism. Background Art

[0002] A concentrator is a device used to evaporate or remove solvents from liquids. Usually, the solvent in the liquid is evaporated by heating, and then the vapor is condensed back into the liquid to form a concentrated liquid. The concentrator can be used to remove solvents from liquids, increase liquid concentration, recover solvents, etc. It is widely used in the fields of chemistry, pharmaceuticals, food processing, etc.
