4-Layer -50-60℃ Freeze Dryer Machine Fruit Vegetable Vacuum Sublimation Experimental 1.1KW 110V

Introduction: <br>Vacuum freeze drying is the removal of water or other solvents from the frozen samples. During the whole drying process, the sample is in a 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 easily denatured at high temperature, and the dryer can ensure that the properties of other compounds will not change. Most of the biological products will be 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 tissue. It is also the best method for drying inorganic materials, such as nano particles, because the surface areas of particles are almost unchanged. <br>Note: <br>Customers are requested to bring their own special oil for the vacuum pump. <br>Paper, cloth, or similar materials do not near the gas circulation pathway , otherwise heat exchange may be blocked. <br>Freeze dryer should be placed horizontally, and the ambient temperature is about+10℃~32℃. <br>The clearance between dryer and wall should be more than 40cm, to keep enough airflow. Never near the heater or other heat source. Never be in sunlight directly. <br>The lack of air circulation or the high ambient temperature can cause the phenomena that the pressure or temperature of the refrigeration system is higher and is even larger than the allowable operating pressure or temperature, and the failure will occur. <br>How It Works: <br>Vacuum freeze-drying is one of the most gentle ways to dry. It is based on the sublimation principle, that is, the physical phenomenon of directly converting the solid phase into the gas phase occurs. The to-be-processed 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 needed energy 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, and analytical drying. <br> <br>Parameter: <br>Voltage: 110V 60HZ <br>Power: 1550W <br>Cold Trap Temperature: ≤-40℃ <br>Drying Temperature: -25~+60℃ <br>No Load: &lt;5PA <br>Water Catch Capacity: 4KG <br>Separator: Four Layers with Heated Separator <br>Partition Size: 210MM*430MM <br>Partition Spacing: 45MM <br>Material Tray Size: 200MM*425MM, 4 Pieces <br>Processing Capacity: 5KG/Batch <br>Freeze Dried Area: 0.4 Square Meters <br>Pump Speed: 2L/S <br>Motor Power: 370W <br>Rotary Speed: 1700R/MIN <br>Voltage: 110V 60HZ <br>Noise: 63DBA <br>Inlet Diameter(Outer Diameter)(MM): G3/4(φ12) <br>Oil Capacity: 1L <br> <br>Items Included: 022799-EnzT <br>Vacuum Sublimation Dryer 110V
