ⅠIntroduction

The vacuum freezing–drying technology, which is also called sublimation drying, is a technical method that freezes the samples in advance, and then sublimates its moisture in the vacuum state. Goods are easier for long-term preservation after freezing-drying processing. They can be restored to the original state and maintain its chemical and biological characteristics after being watered. So the freezing-drying technology is widely used in medicine, food, chemistry industry and biological products etc.

This type freezing dryer is a new patented product. It has changed the traditional tedious operation and has realized the automation.

Ⅱ Characteristics and technical indices

  1、Main characteristic

     (1)The process of pre-freezing and drying finishes in situ. The freeze dryer is equipped with observation windows and the drying process is intuitive.

     (2)The shelf temperature control error is less than 1.0℃.The drying effect is uniform.

     (3)The shelf temperature is adjustable and controlled.

     (4)The drying chamber and condenser is separated so the water-capture capability is higher and the drying time is shorter.

     (5) Touching-screen operation, PID control, Display drying curve, the record device is available.

     (6) The product tray is square so it’s easy to clean and operate.

     (7) Valve with nitrogen is optional.

     (8) The drying chamber adopts transparent ACRYLIC door, and the changing process of product is visible.

  2、Technical indices

 (1) Condenser temperature: -70℃ (empty)

 (2) Shelf temperature range:-50℃~70℃

 (3) Ultimate vacuum degree: less than 10Pa (empty load)

     (4) Shelf dimension: the size of the tray is 475mm*355mm,6layers.

Ⅲ Working conditions
