1. The drying tank of vacuum freeze dryer is made of stainless steel (reinforced with carbon steel anti-rust). All the connectors inside the tank except the I-steel guide rail are made of stainless steel, and the metal hose connected with the heating plate is made of stainless steel, flange connection to prevent vibration. 2. In order to meet the needs of production, we provide one set of skip car and material tray for one set of equipment. The material tray is made of aluminum alloy, the skip car and the hanging rail are made of stainless steel SUS304, the skip car hanging rail is made of carbon steel, anti-rust treatment. 3. Refrigeration, heating, vacuum, electrical, rail transportation and defrosting systems are all controlled automatically Especially the rail transportation system adopts pneumatic control.

.png) | Rear type disposable water capture: The technology of making the frozen water-bearing material undergo ice sublimation (adsorption water evaporation) to escape from
the material as water vapor, and condense the water vapor with the water trap, so as to obtain the dry products |
.jpeg) | Lyophilized into the front section of the warehouse: In the sublimation drying process, the vacuum pressure in the drying chamber should be lower than the saturated vapor pressure corresponding to the eutectic point temperature of the material. |
| Lyophilized rear section of cold trap: Desorption drying is to remove the unfrozen part of water (called adsorption water) adsorbed on the capillary wall and polar gene of the material to ensure the good quality of lyophilized products. |
 | Freeze-dried skip truck tray: For the materials on the tray, the upper surface is the best, the lower surface is the second, and the center part is the worst. With the heating, the material has been dry layer (free water layer) from the upper and lower surface gradually to the central part of the advance. |
 | Freeze-drying with fluorine refrigeration system: Fluorine refrigeration unit is small in size, occupies less space, does not need to set up a separate machine room, greatly saving space, low noise unit, all valves are fully closed valve parts, safe operation. |
 | Germany Laibo vacuum pump group: 1. Oil-free vacuum pump-Because there is no oil lubrication in the vacuum chamber, the dust will not remain in the pump chamber, but with the gas discharged from the exhaust port outside the pump. 2. Oil-free compressed vacuum pump Because the gas is compressed in the pump, the power consumption is low. |
Instructions on food freeze dryer equipment:
1. Customize according to the planned production capacity, and use the incoming batch as a reference.
2. When the production capacity is customized, the configuration of the host used by the freeze-drying equipment is unchanged, and the volume of the product freeze-drying warehouse is changed.
3. The freeze dryer equipment is transported in the whole cabinet, and the foreign on-site installation service is suspended. When installing, you can find a local mechanical engineer for on-site installation. The specific content of the customized contract shall prevail.
4. Reference for the conventional capacity of food freeze-drying equipment: 50 square meters, 80 square meters, 100 square meters, 120 square meters.
5. The price of the freeze-drying equipment production line is subject to the price of the customized model.
