Overview

Product Structure

Consists of a heating cylinder, material distribution device, film-scraping assembly, vapor-liquid separator, and discharge system. The heating cylinder features a jacketed structure, with the film-scraping assembly inside driven by an electric motor. The vapor-liquid separator is located at the top of the unit.

Operating Principle

Material is fed to a distribution device at the evaporator top, where rotating wipers spread it into a uniform thin film on the heated inner wall. Thermal energy from the heating jacket induces rapid evaporation. High-speed wiper rotation optimizes heat/mass transfer while driving the concentrated product downward for discharge. Secondary vapor passes through a vapor-liquid separator for purification before condensation.
