China Factory Suppliers of Model FZG Square and Model YZG Round Static Vacuum Dryers for Heat Sensitive Materials
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 vacuum dryer heats and dries raw materials under a vacuum state. By using a vacuum system to continuously extract air and humidity, it keeps the drying chamber in a vacuum status, which significantly increases the drying speed and saves energy.
How does the vacuum condition benefit the drying process?
Under vacuum conditions, the boiling point of the raw material decreases, which makes the evaporation process highly efficient. This allows you to reduce the required heat transfer area of the evaporator while achieving the same level of heat transfer.
What heating sources can be used with YZG and FZG vacuum dryers?
The heat source for the evaporation process can be configured to use low-pressure steam or surplus waste steam, which minimizes overall heat evaporation losses.
Are these vacuum dryers compliant with GMP standards?
Yes. The dryer can be fully disinfected before the drying process begins. Throughout the drying cycle, the sealed vacuum system prevents any impurities from mixing into the raw material, ensuring full compliance with GMP requirements.
Will the static type vacuum dryer damage the shape of the raw material?
No, since these are static type dryers, the raw materials remain stationary on the baking shelf. This ensures that the integrated shape and structural integrity of the raw materials are not damaged during operation.
Can solvents in raw materials be recovered during drying?
Yes. If a condensator is used, the solvent in the raw material can be recovered. However, if you use an SK series water ring vacuum pump or a ZswJ series hydraulic inject vacuum pump set, the condenser is not needed, which helps save on initial investment costs.
