TECHTONGDA® Food Vacuum Lyophilizer Freeze Drying Machine 4Layers Commercial Freeze Dry Dryer Touch Screen 110V with Vacuum Pump 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. Parameters: HOST: Voltage: 110V60Hz Power：1550W Cold trap temperature: ≤-40℃; Drying temperature: -25~+60℃ No load: <5Pa Water catch capacity: 4KG Separator: Four layers with heated separator Partition size: 210mm*430mm; Partition spacing: 45mm; Material tray size: 200mm*425mm, 4 pieces Vacuum pump: Pump Speed:2L/S Motor Power:370W Rotary Speed:1700r/min Voltage:110V60Hz Noise: 63dBA Inlet diameter (outer diameter) (mm): G3/4 (Φ 12) Oil capacity: 1L Attention: Customers are requested to bring their own vacuum pump specific oil. Features: 1.The machine adopts Tecumseh or Secop, rapid cooling 2.LCD control system, easy to operation, and powerful function 3.The dry room door is made of colorless transparent organic glass, and the whole process of freeze drying can be observed. 4.The vacuum pump is connected by international standard KF quick connector. 5.Stable performance, easy operation and low noise. How it works: 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. 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 You can make order with no worry. Any concern just feel free to let us know, we'll reply in 24 hours in normal condition.
