Vacuum Spherical Evaporator
Application
This spherical concentrator is ideally suited for the concentration and recovery of heat-sensitive materials across a wide range of industries, including pharmaceuticals (both traditional Chinese and Western medicine), food and beverage (glutamate, dairy, glucose, starch, juice), biotechnology, and chemical processing.
Equipment Structure:
It is mainly composed of four parts: spherical concentrator body, condenser, vapor-liquid separator, and receiving tank.

Working Principle
Steam is introduced into the jacket of the spherical tank, where it heats the material to its boiling point. This process vaporizes the water or other volatile components within the material, thereby achieving gas-liquid separation.
Vapor from the evaporation chamber first passes through a foam remover to eliminate entrained droplets, then proceeds to the condenser and cooler where it is liquefied. The resulting condensate is collected in a storage tank, while any non-condensable gases are either vented to the atmosphere or extracted by the vacuum pump.
To terminate the concentration process, close the steam inlet valve and open the evaporator vent valve. This releases the vacuum within the system, allowing the concentrated product to be discharged.
Features
The reduced-pressure concentration process significantly shortens processing time and, by lowering the boiling point, effectively preserves the active components of heat-sensitive materials.
This method enables rapid evaporation and achieves a high concentration ratio. For typical herbal medicine extracts, the relative density of the resulting concentrate can reach 1.3-1.4.
