Product Description

Introduction for Freeze drying technology:

     Freeze-drying, also known as lyophilisation, or cryodesiccation, is a dehydration process typically used to preserve a perishable material or make the material more convenient for transport. Freeze-drying works by freezing the material and then reducing the surrounding pressure to allow the frozen water in the material to sublimate directly from the solid phase to the gas phase.

 

     The freeze drying process is to freeze the materials firstly, and after frozen the products will be load into the vacuum drying tank which will bring the vacuum environment for the ice to sublimate to vapor, and with the condenser inside the tank condense the vapor to ice on the surface of the coils, the products will be dehydrated.

 

Working principle of Freeze drying

     The technology of Vacuum freeze drying is mainly utilizing the principle that water will sublimation directly from ice to vapor when it is in some specific vacuum environment. The freeze drying process is to freeze the materials firstly, and after frozen the products will be load into the vacuum drying tank which will bring the vacuum environment for the ice to sublimate to vapor, and with the condenser inside the tank condense the vapor to ice on the surface of the coils, the products will be dehydrated.


Advantages of Freeze dried products:

    There are several advantages of freeze-dried products when compared to regular hot air dried products.

1) The freeze dried products have long preservation time. If a freeze-dried substance is sealed to prevent the reabsorption of moisture, the substance may be stored at room temperature without refrigeration, and be protected against spoilage for many years. Preservation is possible because the greatly reduced water content inhibits the action of microorganisms and enzymes that would normally spoil or degrade the substance. 

2) Easy transportation. With light weight and well packed freeze dried products can be easily transport by normal containers or any other transportation method. No needs for cold storage facilities therefore save a lot of cost for transportation.

3) Better quality products. Freeze drying causes less damage to the substance than other dehydration methods using higher temperatures. Freeze-drying does not usually cause shrinkage or toughening of the material being dried. In addition, appearance, flavors, smells and nutritional content generally remain unchanged, making the process popular for preserving high quality food.

4)   Extremely high rehydration capacity. Freeze-dried products can be rehydrated (reconstituted) much more quickly and easily because the process leaves microscopic pores. The pores are created by the ice crystals that sublimate, leaving gaps or pores in their place. This is especially important when it comes to instant or convenient food uses.

 

Performance characteristics

Pre-freeze drying is carried out in situ, with an observation window inside, and the drying process is intuitive and controllable;

Dry room temperature difference 1 ° C, uniform drying effect;

The temperature of the partition is adjustable and controllable. It can explore the pilot test and the production process. Because the drying chamber and the cold trap are separated structures, the water-capacity is strong and the drying time is long;

An inflatable valve is provided to dry the inert gas;

The drying chamber adopts the aviation acrylic high transparent transparent colorless door, and the change process of the material can be clearly observed during the lyophilization process;

Pre-freeze drying is carried out in situ, which reduces the cumbersome operation of the drying process and realizes automation;

Embedded touch screen, PLC controller, PID temperature adjustment, freeze-drying curve and historical curve;

U disk dump data;

Equipped with PC software, it can print, browse curves and data.
