Product description:
1.The principle of Freeze-drying
The drying process is as follows: Firstly, the internal moisture of food has been frozen in the low-temperature environment. secondly, In the drying step, the ice inside the previous raw material will directly be converted into steam evaporation during a near-vacuum environment. Finally, the internal moisture of food will dramatically decrease. The whole dewatering process is under a lower temperature environment than that of a traditional dryer.
2.The advantages of freeze-drying
1.In the freeze-drying process, the growth of microorganisms and the role of enzymes can not be carried out.In the freeze-drying process, the growth of microorganisms and the role of enzymes can not be carried out.
2.The volume is almost unchanged and the original structure is maintained.
3.The surface hardening of the material will not be caused because the moisture in the material exists in the form of ice crystal after freeze drying.
3.Applied range
1. Pet food: it can be used for freeze-drying processing of egg yolk, chicken breast, duck, beef, quail, dried fish, liver, etc.;
2. Food industry: In the food industry, it is mainly used for freeze-dried fruit and vegetable crisp, coffee, scented tea, mushrooms, fruit and vegetable juice, strawberries, whole shrimp, meat, specialty vegetables, freeze-dried instant soup, freeze-dried porridge, etc.;
3. Nutrition and health care: it can be used to process royal jelly freeze-dried powder, pearl powder, ginseng, tortoise powder, snake powder, etc. It can store its nutrients and active ingredients for a long time to ensure the naturalness of nutritional health products;
4. Biological products: bait for sea fishing (Jellyfish), ants, insect food, etc.;
5. Chinese herbal medicine: Cordyceps, Maca, plant extracts, Panax notoginseng, etc.
Main Features:
1.The freeze-dried box and partition are made in strict accordance with GMP requirements. The cylinder is made of grade 304 stainless steel and the interior is mirror polished. The production process and requirements are higher than the current domestic conventional food freeze dryer manufacturers.
2. Adopt the integrated cold trap of the box body, the design of the front box and the rear trap, compact structure, with an observation window, and the observation window is equipped with a lighting device to facilitate observation of the situation in the box. Designed into a structure or form that is easy to clean and has no sanitary corners.
3. The coil for water trapping of the cold trap is made of clean stainless steel. The integral structure or the split structure can be selected according to customer needs.
4.The refrigeration system components are configured according to high-standard imported brands, with strong refrigeration capacity, fast cooling speed, stable and reliable performance.
5.Use soaking or steam defrosting to quickly defrost and clean.

Product details:
1.Drying chamber
The chamber, where freeze drying process occurred, is cylinder shaped with multiple reinforcing ribs to strength. The chamber, doors are constructed in SUS304 stainless steel. The chamber contains both the product shelves and the vapor condenser in side.The chamber is fitted with valves of vacuum line connection, drain, water defrost and vacuum release. The chamber has two doors - one at each end. The one is for products loading / unloading; the other is at the condenser end. The doors and chambers are sealed by silicon rubber to avoid any vacuum leaks. The doors have an opening angle of 110. The hinges will be either left or right hand side, to be specified by the customer. Closing is by means of four quick acting latches. Each door has viewing port. The frame of viewing ports is made of 304 stainless steel and toughened glass window, to allow visual monitoring of both the vapor condenser and product. Track is suspended on the ceiling of inside the chamber to allow trolleys hang and move.
2.Shelf and trolley
A particular number of 'modules' are consisting of a number of shelves on where are available for product loading, with the top plate providing radiant heat only.The product is placed in trays, which are loaded onto the heat-plates (shelves) in the
freeze dryer. The heat-plates can be chilled and heated, so the machine is capable of freezing product in place or pre-frozen in IQF. The heat-plates are fabricated by SUS304 stainless steel or aluminum, and have a flat upper side and heating fluid
channels on the underside. The trolleys of large scaled lyophilizers are fitted with wheels that run in a track located above the chamber, allowing each trolley to be wheeled outside of the chamber.
3.Vacuum system
The vacuum system is composed of drying chamber, condenser, vacuum pipes, valves and back pump and holding pump. It requires no leaks; Vacuum system is an essential for the rapid sublimation. Backing pumps and holding pumps are required for large scaled system to give efficient capacity for evacuation. Brand: Leybold, Yoivac etc.
4.Refrigeration system
The refrigeration system freezes the heat plates during in-place freezing, evacuation and the early stages of drying. It also cools the vapor condenser during the drying cycle. The screw compressor is adopted on the large scaled equipment and piston for small ones, and the refrigerant used is R404A, R507. Brand option: Refcomp, Bitzer.
Remarkable advantage of freeze-dried food:
1.Retain biological activity
2.No damage to the nutrition
3.Taste, color and appearance
4.Longer shelf-life
