Vacuum drying is ideal for materials that would be damaged or changed if exposed to high temperatures. The vacuum removes moisture while preventing the oxidation or explosions that can occur when certain materials combine with air. Vacuum drying is also ideal in situations where a solvent must be recovered or where materials must be dried to very low levels of moisture.
Vacuum
Drying Saves Time
Unlike atmospheric
drying, drying under reduced pressure lowers the boiling point and provides
a greater temperature difference between the heating medium and product.
This results in faster drying and more efficient heat recovery.
Vacuum
Drying Saves Money
Drying at
lower temperatures reduces energy consumption. The dryers' closed-system
design allows costly solvents to be recovered, eliminates expenses for
additional air pollution control or exhaust systems, and minimizes product
loss caused by atmospheric contaminants, dusting, oxidation, discoloration,
and chemical change.
Vacuum
Drying Protects Workers
Since drying
occurs in a closed system, hazardous materials and fumes are not released
into the air. The potential for explosions is reduced because of the lower
temperatures and the lack of dust and air in the dryer.
This vacuum shelf dryer is designed with two independent chambers for drying two types of materials at the same time.
