Aluminum Vacuum Evaporator Double Effect Fallling Film Evaporator for Animal Milk

It can be divided into atmospheric, pressurized, and vacuum evaporation operations. Obviously, for heat sensitive materials such as antibiotic solutions, fruit juices, etc., they should be processed under reduced pressure. High viscosity materials should be evaporated using a pressurized high-temperature heat source for heating (such as heat transfer oil, molten salt, etc.)

It can be divided into single effect and multi effect evaporation. If the secondary steam generated by evaporation is directly condensed and no longer used, it is called single effect evaporation. If the secondary steam is used as the next heating steam and multiple evaporators are connected in series, this evaporation process is called multi effect evaporation.

Natural evaporation: refers to the evaporation of a solution at a temperature lower than the boiling point, such as when salt is exposed to seawater. In this case, due to the solvent only vaporizing on the surface of the solution, the solvent vaporization rate is low.

The indirect heat source heats the walls of the container and transfers it to the evaporated solution. The heat transfer process carried out in a wall type heat exchanger.
