Product Details

National standard vacuum freeze dryer for apple

1.Specail

Vacuum freeze drying technology is the most advanced food processing technology ofdehydrated, commonly used drying method and compared with the technology of production of freeze dried food, with shelf life long, good rehydration, and its color, smell, taste, nutrition and taste etc., dried food volume and shape invariant, material is sponge, no shrinkage of the phenomenon can be widely used in the field of vegetables, fruits, spices, aquatic products, biological products, medicines, beverages and specimens

2, Working principle

So called vacuum freeze drying is to make water cut material, after the pretreatment, the -30 is rapid freezing and vacuum environment, so that the water from the solid into the gas, to remove the moisture and the preservation of the material drying method

3. Product description

SJFD series vacuum drying equipment frozen is my company in the absorption of foreign advanced technology, combined with the advantages of peer products based on and developed a new generation of food processing equipment, the company for a long time, food processing industry and made new contribution XZD series of vacuum freeze drying equipment mainly includes: Food pre freezing system, dry sump system, heating system, vacuum system, refrigeration system, material conveying system, media system, gas system, cleaning and disinfection system.

4. Product features

1. The vacuum system uses the combination of seal water pump and oil pump, initially excluded air by high power oil seal pump group rapid pre pumping, maintain vacuum with small power roots water seal pump working group. Can reduce energy consumption and water seal pump and pull in water vapor, to avoid the oil seal pump due to poor drainage performance, water vapor so that pump oil emulsion deterioration, drawbacks and cause system unstable vacuum.

2. heating is a closed circulating water system, the three-way regulating valve automatically adjust the amount of heating water circulation system, precise control of heating temperature, and nitrogen automatic constant pressure, ensure the hot water temperature to 120 degC.

3. the rear mounted and floating trap water wells, and compared to the explant type cold trap, shortest path, small resistance, water vapor channel design flow capture uniform water, improve water catching efficiency. The unique way of the single cycle refrigeration of ammonia in the water - cooled trap is a special way of refrigeration. Small and medium sized equipment adopts freon refrigeration, by adjusting the expansion valve for flow.
