Product description

Freeze-drying machine (freeze-drying machine) consists of refrigeration system, vacuum system, heating system and electrical instrument control system. The main components are drying oven, condenser, refrigerating unit,acuum pump, heating and cooling device, etc.

Freeze-drying, referred to as freeze-drying, is the method of freezing water-containing material into solid state first, and then sublimating the water from solid state to gas state,
so as to remove the water and preserve the material.The application of freeze-dried food is mainly in the convenience food industry, soup processing industry, instant drinks industry, nutrition and health products industry andquartermaster, field work, mountaineering, aerospace and other special industries.

There are many kinds of freeze-dried foods in foreign countries, which have exceeded the products stored or processed by any of the refrigerat-ed, frozen, canned and other hot-drying methods. For example, the main ingredients used in the food industry: coffee, honey, cocoa powder, egg powder, shellfish juice powder and vegetable juice powder; Home cooking
staples: Japanese shrimp, tofu, ltalian tomatoes and Hungarian red bell peppers; Condiments and ingredients: green onion, ginger, garlic, pepper, matsutake, basil, drowned vegetables, bean paste, natural spices andpigments; Fruit: Peruvian maca, American cherry, American pineapple, yellow peach, mango, white peach and ltalian citrus; Special (aerospace, aviation, navigation, field work, polar, military and tourism, etc.) and convenient fast

food: American salad, convenient meals, Japanese cup noodles, Japanese instant sauce soup, jam, cheese, tea and so on.Fd series food vacuum freeze-drying machine mainly includes; food pre-freezing
system, drying bin system, heating system, vacuum system, refrigeration system, material transfer system, media system, pneumatic system, cleaning and disinfection system.

Main principle

After the machine is started, the material is put into the material box for the freezing process of the material. On the one hand, the vacuum system is vacuumized to take part of the water away; On the other hand, when the material is frozen, the water content in some molecules is discharged to the surface of the material and frozen. After meeting the freezing requirements, the material is heated and dried by the heating system, and the water contained in the material is brought to the freezing collection box through vacuum-pumping to freeze the material, so as to meet the freezing drying requirements.
