Automatic Freeze Dryer

Automatic freeze dryer

Food freeze-drying equipment (also known as food freeze-drying machine) is the principle that water is pre frozen into solid state at low temperature, and then sublimated into gas directly without liquid in vacuum environment. Food freeze-drying equipment is used for vacuum freeze-drying of various foods, such as freeze-dried fruit crisp, freeze-dried fruit and vegetable powder, freeze-dried vegetable granules, freeze-dried coffee, freeze-dried tea, freeze-dried fresh milk, freeze-dried seafood, freeze-dried meat and other food freeze-drying processing and production. Because the food freeze dryer equipment operates in low temperature and vacuum environment, it can keep the food nutritional composition, color and shape basically unchanged, has the advantages of good rehydration, long-term preservation and transportation, so the freeze dryer is widely used in various food drying, processing and production.

Food freeze-drying machine equipment is divided into contact freeze-drying machine and radiation freeze-drying machine according to material heat exchange mode. Most enterprises in the market choose the radiant freeze dryer production line. The operation process is because the partition of the material warehouse has no refrigeration function. It needs to pre freeze and crystallize in the pre freezing warehouse outside the food freeze-drying warehouse, and then transfer it to the material warehouse through the guide rail. After closing the warehouse door, start vacuum drying. Because the partition has no refrigeration capacity, the temperature control drying temperature can only be from room temperature to 120 ℃, As a result, most food freeze-drying processes cannot be met, the operation of food freeze-drying equipment needs manual intervention, and the loss of nutritional components of freeze-dried materials leads to problems such as discoloration, collapse deformation and no rehydration of dried materials.

Automatic freeze dryer adopts the contact type, because the material is in direct contact with the diaphragm, which can accurately control the temperature. The diaphragm of the contact type food freeze dryer has refrigeration capacity, and the whole process of in-situ pre freezing vacuum drying can also be started with one button. The PLC electric control of the equipment can set the process parameters, because the temperature control range of the low-temperature freeze drying equipment is - 50 ~ + 80 ℃, It has the functions of curve temperature control and vacuum fine adjustment to meet the requirements of most food freeze-drying processes. Moreover, the equipment adopts contact type to ensure accurate direct heat exchange and temperature control. In addition, the PLC electric control system of food freeze-drying machine has the functions of process setting, storage, tracking and authority management, as well as remote control. The PLC of food freeze-drying equipment controls the whole freeze-vacuum drying operation, Because the food freeze-drying equipment has the functions of low temperature, accurate temperature control of curve, vacuum fine adjustment and so on, it can ensure that the nutritional composition, color and body shape of food drying materials are basically unchanged, and has rapid rehydration. Therefore, the new contact food freeze-drying function operates automatically without manual duty. It can ensure the quality of food drying materials through remote monitoring and realize industrial production management. Provide modern food lyophilizer equipment for enterprises.
