Static Vacuum Dryers in China: Model FZG Square & Model YZG Round - Trusted Suppliers & Factory Solutions
Principle
To heat and dry raw material under the state of vacuum is called vacuum drying. It use vacuum to pump air and humidity out. Making the work-room on the vacuum state. The drying rate increases greatly and energy is saved.
Remark: If use condensator, the solvent in raw material can be recovered. If use SK series water ring vacuum pump or ZswJ series hydraulic inject vacuum pump sets, condenser can not be used and the investments could be saved.
Features
- Under the condition of vacuum, the boiling point of raw material will decrease and make the evaporation's efficiency higher. Therefore, it can save the conducting area of evaporator under the same quantity of heat transfer.
- The heat source for evaporating can be low pressure steam or surplus waste steam.
- The heat of evaporation loss is less.
- Before drying, the dryer can be disinfected. During the period of drying, there is no impurity material mixed. It is in conformity with the requirement of GMP.
- It is static type dryer. So integrate shape of raw material will not be damaged.

Frequently Asked Questions
What is the working principle of the vacuum dryer?
The principle is to heat and dry raw materials under a state of vacuum. It uses a vacuum pump to extract air and humidity, putting the work chamber in a vacuum state, which greatly increases the drying rate and saves energy.
Can the solvents in raw materials be recovered during drying?
Yes. If a condensator is used, the solvent in the raw material can be recovered. If you use a SK series water ring vacuum pump or ZswJ series hydraulic inject vacuum pump sets, a condenser is not needed, which can save investment costs.
How does the vacuum condition improve evaporation efficiency?
Under vacuum conditions, the boiling point of the raw material decreases, which makes the evaporation efficiency higher. Consequently, it saves the heat conducting area of the evaporator under the same quantity of heat transfer.
Does the static vacuum dryer meet GMP requirements?
Yes, the dryer can be disinfected before drying. During the drying period, no impurity materials are mixed into the raw materials, which is in full conformity with GMP requirements.
Will the physical shape of the raw material be damaged during drying?
No, since it is a static type dryer, the integrated shape of the raw material will not be damaged during the drying process.
What heat sources can be utilized for evaporation in this dryer?
The heat source for the evaporation process can be low pressure steam or surplus waste steam, making it highly adaptable and energy-efficient.
