ZKG series of vacuum drying chamber
ZKG serial vacuum drying oven takes the dry material in a vacuum condition for heated drying. Utilizing of vacuum pump for air exhaust and wet exhaust will speed up the drying rate. If using the condenser, the solvent in materials can be recycled through the condenser.
Characteristics
The boiling point of material solution shall be depressed under vacuum condition, making the driving force of heat transfer for the evaporator increase, therefore, the heat transfer area of the evaporator can be saved for certain heat transmission.
Disinfection treatment could be done before drying process; none of the impurity shall be mixed in during the process of drying, which will be in line with the GMP requirements. It is a kind of static vacuum dryer; so the shape of the dry material will not be damaged.
