Working principle of freeze dryer

Freeze drying is a kind of technology that the water content materials freeze at first, and then get the dry goods in the vacuum state through sublimation. The items of freeze drying processing are easy to be preserved for long time, and can be restored to the state before freezing and the biochemical characteristics. For heat sensitive substances such as antibiotics, vaccines, blood products, enzyme hormone and other biological products, freeze drying technology more show its superiority.

"Toffon" library freeze dryer has a mature manufacturing process, superb temperature control technology, the ultra low working temperature and high efficiency service. In the present, the production freeze dryer is the freeze dry machine innovation backbone; the final temperature has reached to 200 degrees below zero. In the products of nutrition preservation, preservation freeze dryer has a great advantage. For some special items which the lower the temperature, the higher the rate, freeze dryer also provides better working environment.

Library freeze dryer characteristics:

1. Touch screen display, curve and data show the drying process, PID function adjust, to facilitate the user easier to understand information.

2. Compound refrigeration technology, less frozen dry time. Import key parts, reducing noise, large freezing capacity, and large water capture capacity. High quality makes sure high performance.

3. The material tray is made of 304 stainless steel, strong and easy to operate and clean.

4. The drying chamber’s door is made of high transparent and colorless transparent organic glass, and can be clearly observed during operation.

5. All 304 stainless steel inside, to keep anti-corrosion and easy clean.

6. Configuration of pneumatic valve can be filled with dry inert gas

7. Optional for in situ pre freezing, the automation from vacuum to dry achieved to reducing the complex operation in the drying process..

8. Optional temperature recorder. The adjustable temperature record point, real-time monitoring, so do not fear of forgetting, security for your experience accumulation.

9. Optional eutectic point test device, and automatic pressure plug device.
