Vacuum salt Continuous evaporation crystallizer machinery
It is a natural circulation device operated under vacuum conditions. condense continuously under vacuum conditions of low temperature to insure quality. Raw material flowed by pump due to the less flow ability of raw material.
Vacuum evaporation
it is the process of causing the pressure in a liquid-filled container to be reduced below the vapor pressure of the liquid, causing the liquid to evaporate at a lower temperature than normal. Although the process can be applied to any type of liquid at any vapor pressure, it is generally used to describe the boiling of water by lowering the container's internal pressure below standard atmospheric pressure and causing the water to boil at room temperature.
When the process is applied to food and the water is evaporated and removed, the food can be stored for long periods of time without spoiling. It is also used when boiling a substance at normal temperatures would chemically change the consistency of the product, such as egg whites coagulating when attempting to dehydrate the albumen into a powder.
