Freeze Dryer Food Fruit Vacuum Freeze Drying Machine Freeze Dryer Equipment for food flower candy soup
vacuum freeze drying is the removal of water or other solvents from the frozen samples. During the whole drying process, the sample is in liquid state and the temperature is generally lower than -10. The purpose of vacuum freeze drying is to restore the original characteristics of the sample after rehydration.
Because the drying process is carried out at low temperature, it can be used for some materials such as proteins, which are easy to be denatured at high temperature, and can ensure that the properties of other compounds will not change.
Most of the biological products, such as tissues, tissue extracts, bacteria, vaccines and serum, were changed into dry samples by vacuum freeze-drying. Vacuum freeze drying is the most gentle process to preserve the biochemical properties of sensitive tissue or other tissues. It is also the best method for drying inorganic materials, such as nano particles, because the surface area of particles is almost unchanged.
Vacuum freeze drying technology, also known as sublimation drying, is a method of pre-freezing water-containing substances and sublimating the water under vacuum. The original biological and chemical properties of freeze-dried products remain basically unchanged and are easy to store for a long time. After adding water, it can be restored to the state before freeze-drying and maintain its original biochemical characteristics. Therefore, vacuum freeze-drying technology is widely used in medicine, food, chemical industry, biological products and other fields.Freeze-dried food can be stored for up to 25 years. Freeze-dried food is ideal for home storage.
The samples with high acid or solvent content can not be dried in the absence of special protection (if necessary, please contact the service department), otherwise the freeze dryer may be corroded. When drying containing azide should pay more attention to it, because with copper or other non ferrous metal reaction will explode.

Installation step
(1)Open the package, check the components according to the packing list;
(2)Fill the pump’s oil into pump to the middle of the level guide.
Remark: Please using required oil type;
(3)Connect the pipe between pump and dryer by connectors. One side is fixed on pump’s air inlet, the other side is fixed on dryer’s vacuum outlet;
(4)Connect the pump’s power plug into dryer’s vacuum pump power outlet;
(5)Connect the power wire to dryer’s main power outlet, other side connect to power supply(with ground wire );
(6)Turn on the switch, test step by step according to the instructions. When all the technical data are satisfy (including vacuum <15Pa, condenser chamber’s temperature <-35℃), the dryer could be put into usage.
