China Suppliers Factory Model FZG Square & 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 dryer heats and dries raw materials under a vacuum state. By using a vacuum pump to draw out air and moisture, it creates a low-pressure environment inside the drying chamber, which significantly accelerates the drying rate and saves energy.
Can solvents contained in the raw materials be recovered?
Yes. If a condenser is connected to the system, the vaporized solvent from the raw materials can be cooled down and successfully recovered.
How does vacuum drying help save energy and evaporator area?
Under vacuum conditions, the boiling point of the raw material decreases, which increases the evaporation efficiency. This allows for a smaller heat-conducting area on the evaporator while transferring the same quantity of heat.
Is this equipment suitable for GMP-compliant production?
Yes, the dryer can be fully disinfected before operation. Because the drying process takes place in a sealed vacuum chamber, no external impurities can mix with the materials, meeting strict GMP requirements.
What are the benefits of using a static vacuum dryer?
Since it is a static type dryer, the raw materials remain stationary during the drying process. This ensures that the original physical shape and structure of the materials are completely preserved and undamaged.
What heat sources can be used with the FZG and YZG dryers?
The system is highly versatile and can use low-pressure steam or surplus waste steam as the heat source for evaporation, helping to reduce overall operational costs.
