Purpose:

Suitable for low-temperature drying of heat sensitive materials that are easy to decompose, polymerize and deteriorate at high temperatures; It is widely used in pharmaceutical, chemical, food, electronics and other industries.

Principle:

The so-called vacuum drying is to heat and dry the dried materials under vacuum conditions. If the vacuum pump is used for air extraction and moisture extraction, the drying rate will be accelerated.

Note: If a condenser is used, the solvent in the material can be recovered through the condenser; If SK series water ring vacuum pump is used, the condenser can be used to save energy investment.

Feature:

■ The boiling point of the material solution decreases under vacuum, which increases the driving force for heat transfer of the evaporator. Therefore, a certain amount of heat transfer can save the heat transfer area of the evaporator.

■ Low pressure steam or waste heat steam can be used as the heat source for evaporation operation.

■ Less heat loss of evaporator.

■ Disinfection treatment can be carried out before drying, and there is no impurity mixed in the drying process, meeting the GMP requirements.

■ It is a static vacuum dryer, so the shape of the dried materials will not be damaged.
