Working principle of pulse vacuum dryer for traditional Chinese medicinal materials
The pulse vacuum dryer for traditional Chinese medicinal materials puts the material into a drying tray and places it on a flat plate heated in the box. Under vacuum, through continuous pressure reduction and pressure increase, the solvent is carried away by the vacuum pump (and can add a condensation recovery system) to achieve the purpose of rapid drying.
Structural characteristics
Square vacuum dryer consists of main unit, vacuum system, heating system, control system and other parts.
The main machine adopts a square design and has a large capacity and drying area, which can accommodate more substances for drying.
The vacuum system pumps out air from the container to form a vacuum environment.
The heating system uses heating elements such as electric heating rods to heat substances and accelerate the evaporation process.
The control system can achieve precise control and adjustment of the drying process.
Performance characteristics
The boiling point of the material solution decreases under vacuum, which increases the heat transfer driving force of the evaporator, so the heat transfer area of the evaporator can be saved for a certain heat transfer amount.
The heat source for evaporation operation can be low-pressure steam or waste heat steam.
The evaporator has less heat loss.
Disinfection treatment can be carried out before drying, and no impurities are contaminated during the thousand-blasting process, which meets GMP requirements.
It belongs to a static vacuum dry explosive device, so the shape of the dry explosive material will not be damaged.
Application Range
Square vacuum drying machines are widely used in the following fields:
the chemical industry is used for drying chemical raw materials, such as titanium dioxide, iron oxide, etc.;
the food industry is mainly used for separating and drying food ingredients, such as starch, protein, etc.;
The pharmaceutical industry is mainly used for drying and granulating drugs, such as western medicine, traditional Chinese medicine, etc.;
other industries are suitable for drying materials in other fields, such as papermaking, textiles, etc.
