Vacuum freeze dryer is widely used in medicine, pharmacy, biology research, chemical industry and food production, etc. 

Goods are easier for long-term preservaction after freezing-drying processing, they can be restored to the original state 

and maintain its chemical and biological characteristics after being watered.

TPV series In-situ freeze dryer changes the traditional complicated operation, prevents the pollution of the material and 

realizes the dry sublimation automation.It is suitable for freeze drying experiment in laboratory or pilot scale.

1. Silicone oil heating in-situ vacuum freeze dryer.

2. The process of pre-freezing and drying finishes in situ. The freeze dryer is equipped with observation windows and 

the drying process is automatic.

3. The Temperature error is less than or equal 1℃. The drying effect is uniform.

4. The partition-board temperature is adjustable and controlled.

5. Stored 32programs, each program can be set up 36 segments, correct program data in computing, memorize the 

drying curve.

6. The drying chamber and cold trap is separated so the water-capture capability is higher and the drying time is shorter.

7. Touching-screen operation, PID controlling, displaying drying curve.

8. The sample tray is square so it’s easy to clean and operate.

9. Configuration of the inflation valve, rechargeable dry inert gas.

10. The drying chamber adopts transparent organic glass door the changing process of material is clear.

11. The test device is optional. 

12. Vacuum pump of freeze dryer is available.

Goods are easier for long-term preservaction after freezing-drying processing, they can be restored to the original state 

and maintain its chemical and biological characteristics after being watered. The below is the vacuum freeze dryer case

for food, fruit, vegetable, meat, herb, alga, sea food,flower,etc.
