Applications
Vacuum freeze drying technology is currently worldwide most advanced technology for food dehydration processing. Compared with the commonly used drying method, the freeze-dried food produced with this technology features long period of quality assurance, good re-hydration nature, good-looking color, good flavor, taste and high content of nutritious components. The dried food basically remains unchanged in its volume and shape, looks like sponge and has no shrinking. This drying technology can be widely used in process of vegetables, fruits, condiments, aquatic products, biological products, medicine, beverage and etc.
Working principle
The vacuum freeze drying is a drying method for dehydration and preservation of substances. It sublimes the moisture in the pre-processed substance from solid state into gaseous state by -30 centigrade quick-freezing under the vacuum condition.
JDG series vacuum freeze drying equipment mainly includes food pre-freezing system, drying bin system, heating system, vacuum system, refrigerating system, material conveying system, medium system, pneumatic system, cleaning and sterilizing system.
Main features of JDG series vacuum freeze dryer
1. The vacuum system is in combination structure of water-sealed pump + oil-sealed pump. The extraction of pre-vacuum is performed by oil-sealed pump group of large power and the vacuum for operation remains by water-sealed Roots pump group of small power so as to reduce energy consumption. Meanwhile, the water-sealed pump group can remove vacuity instability of the system due to poor water-removal performance of oil-sealed pump and emulsification deterioration of the pump oil.
2. Heating is conducted in closed water circulation system, where three-way adjusting valve is used for automatic adjustment of heat supply to the water circulation system to precisely control temperature of the heating plate. Besides, nitrogen is used for automatic pressure-keeping to ensure the working temperature of the hot water reaching 120 centrigrade.
3. The rear-installed and side-installed water-catching cold trap is adopted. Compared with the outside-installed cold trap, the former one has advantages of short canal, lower resistance, and smooth steam canal, uniform and high-efficient water-catching. The cold trap uses special method of ammonium single-phase circulating refrigeration. It is more stable in supplying refrigerating liquid and easier in operation than the general method of liquid supply.
