freeze dryer Emergency Prep Easy Save home freeze drying machine
Vacuum freeze-drying is one of the most gentle ways to dry. It is based on the sublimation principle, that is, the solid phase directly into the gas phase of this physical phenomenon. The freeze-dried material is placed in a vacuum drying chamber for drying, and the water vapor produced by the cold trap is condensed to form ice, so as to achieve the purpose of eliminating water vapor. Vacuum pump is used to discharge the air in the drying room, not including water vapor.
The baffle plate is provided with a heating device, and the heat is transferred to the material through the conduction function to provide the energy needed for sublimation. When the free water in the material is sublimated, the internal bound water can also be removed from the material at a very low vacuum. This drying process is considered to be the last stage of drying, analytical drying.
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.
