HFD-4 Vacuum Freeze Dryer Lyophilizer 110V Food Vegetable Freeze Drying Machine

Description: PreAsion® HFD-4 Vacuum Freeze Dryer Lyophilizer 110V Food Vegetable Freeze Drying Machine 4 Trays 　 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 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.

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. 　 Warning：　 1. Paper, cloth, or similar materials do not near the gas circulation pathway or heat exchange may be blocked. 2. Freeze dryer should be placed horizontally, ambition temperature is about+10℃~32℃. 3. The clearance between dryer and wall should be more than 40cm, to keep enough air flow. Never near the heater or other heat source. Never be in sunlight derectly. 4. The lack of air circulation or the high ambient temperature can lead to the pressure or temperature of the refrigeration system higher, or even more than the allowable operating pressure. It will be lead to failure. 　 Item Number: 022799 　 HFD-4 Vacuum Freeze Dryer Lyophilizer 110V Food Vegetable Freeze Drying Machine
