FD Intelligent Vacuum Freeze Drying Machine
The freeze dryer (freeze dryer) consists of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system.
The main components are drying oven, condenser, refrigeration unit, vacuum pump, heating and cooling device, etc.
Freeze drying, also known as freeze-drying, is a method of preserving a substance by first freezing it into a solid state and then sublimating the water from the solid state to a gaseous state, in order to remove the water and preserve the substance.
The application of freeze-dried food is mainly in the convenience food industry, soup processing industry, instant beverage industry, nutritional and health product industry, as well as special industries such as military supplies, field operations, mountaineering, and aerospace. There are many varieties of freeze-dried food abroad, which have surpassed any product stored or processed using refrigeration, freezing, canning, or other hot drying methods. For example, the main ingredients used in the food industry include coffee, honey, cocoa powder, egg powder, shellfish powder, and vegetable powder; Main ingredients for home cooking: Japanese fresh shrimp, tofu, Italian tomatoes, and Hungarian red bell peppers; Seasoning and ingredients: scallions, ginger, garlic, pepper, matsutake, perilla, pickled vegetables, soy sauce, natural spices and pigments; Fruits: Peruvian maca, American cherry, American pineapple, yellow peach, mango, white peach, and Italian citrus; Special (aerospace, aviation, navigation, fieldwork, polar, military, tourism, etc.) and convenient fast food: American salads, convenient three meals, Japanese cup noodles, Japanese instant sauce soup, jam, cheese, tea drinks, etc.
The Fd series food vacuum freeze-drying machine mainly includes: food pre freezing system, drying chamber system, heating system, vacuum system, refrigeration system, material conveying system, media system, pneumatic system, cleaning and disinfection system.

After starting up, put the materials into the material box for the freezing process of the frozen materials. On the one hand, the vacuum system performs vacuuming to remove some of the moisture; On the other hand, when the material is frozen, the moisture contained in certain molecules is discharged onto the surface of the material to freeze. After meeting the freezing requirements, the material is heated and dried by the heating system, and the moisture contained in the material is brought to the freezing capture box for freezing by vacuuming, achieving the freeze-drying requirements of the material.
