Working principle
The so-called vacuum drying is to heat and dry the dry materials under vacuum conditions. If the vacuum pump is used for air extraction and dehumidification, the drying speed will be accelerated.
Note: If a condenser is used, the solvent in the material can be recovered through the condenser. If the solvent is water, the condenser can be used to save energy investment.
Performance characteristics
◎ The boiling point of the material solution under vacuum decreases, which increases the heat transfer driving force of the evaporator, so the heat transfer area of the evaporator can be saved for a certain amount of heat transfer.
◎ The heat source of evaporation operation can be low-pressure steam or waste heat steam.
◎ Less heat loss of evaporator.
◎ Disinfection can be carried out before drying, and there is no impurity contamination in the drying process, meeting the GMP requirements.
◎ It is a static vacuum dryer, so the shape of dry materials will not be damaged.
Applicable materials
Suitable for low-temperature drying of heat-sensitive materials that are easy to decompose, polymerize and deteriorate under high temperature; It is widely used in pharmaceutical, chemical, food, electronics and other industries.
Note: The water ring vacuum pump is combined with mechanical supercharging to improve the vacuum degree.
Ordering instructions
◎ When ordering, please select the appropriate vacuum dryer according to the physical properties, initial moisture content, final moisture content, temperature, vacuum degree, drying amount, drying time and other factors. The vacuum dryer of the same model has four heating modes: steam hot water heat transfer oil electric heating. For example, in order to increase the drying capacity, the number of drying rack layers can be appropriately increased. Please report to our factory in time.
