CE Commercial Use Lyophilizer Beef Vacuum Freeze Dryer Vegetable And Fruit Processing Machine
Product Application:
Freeze drying, also known as lyophilization or cryodesiccation, is a low temperature dehydration process that involves freezing the product and lowering pressure, removing the ice by sublimation.
The vacuum dryer is composed of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. The main components are drying box, water trap (cold trap), refrigeration unit, vacuum pump, heating/cooling device, etc.
Brief description of freeze-drying process:
(1) Pretreatment process
For different materials to be dried, the pretreatment methods are different. According to the characteristics of raw materials, corresponding processing methods are adopted
(2) Pre-freezing process
There are two methods of pre-freezing: vacuuming, self-evaporative freezing and freezing with quick-freezing equipment.
(3) Sublimation drying
Sublimation drying is carried out in a vacuum device, so it is very important to maintain a suitable vacuum during the sublimation drying process.
(4) Post-treatment process
Vacuum freeze-dried food is generally porous and loose, with a large surface area, easy to absorb moisture.
Advantages of Vacuum Freeze Drying Machine:
Because of the low temperature used in processing, the rehydrated product retains much of its original qualities. When solid objects like strawberries are freeze dried the original shape of the product is maintained. If the product to be dried is a liquid, as often seen in pharmaceutical applications, the properties of the final product are optimized by the combination of excipients. Primary applications of freeze drying include biological (e.g., bacteria and yeasts), biomedical (e.g., surgical transplants), food processing (e.g., coffee) and preservation.
The primary purpose of freeze drying within the food industry is to extend the shelf-life of the food while maintaining the quality. Freeze-drying is known to result in the highest quality of foods amongst all drying techniques because structural integrity is maintained along with preservation of flavors. Because freeze drying is expensive, it is used mainly with high-value products. Examples of high-value freeze-dried products are seasonal fruits and vegetables because of their limited availability, coffee; and foods used for military rations, astronauts/cosmonauts, and/or hikers.
