Vacuum Freeze Dryer Manufacturers

Food freeze-drying technology is simply a relatively advanced drying technology. The principle is to first freeze fresh food at low temperatures and then perform sublimation and dehydration under appropriate vacuum conditions. Sublimation dehydrated food is called "freeze-dried food". The shape, color, taste, and nutritional composition of freeze-dried food are basically the same as those of fresh food, and the rehydration is good.

In the past, traditional food dehydration methods include sun-drying, air-drying, drying, spray drying, etc. However, in these traditional high-temperature drying methods, the products obtained by drying are generally reduced in size and hardened in texture, some substances are oxidized, and some are volatile. Most of the components will be lost, and some heat-sensitive substances, such as proteins and vitamins, will be denatured. Microorganisms will lose their biological activity, and the dried substances will not easily dissolve in water.

Using low-temperature drying food freeze-drying technology, not only vegetables, fruits, meat, aquatic products, etc. can be made into dry products to ensure nutrition, but also various medicinal materials can be made into medicines to ensure efficacy, and some liquid foods can also be made into Instant-dry powder. In addition, this technology can also be used for the processing of some special industrial materials (such as nano-scale ceramic materials).

Freeze-dried food has long been favored by consumers in foreign countries because of its freshness, nutrition preservation, no additives, convenient consumption, convenient storage and transportation, and the consumption is increasing year by year. The current annual consumption and foreign demand are large. These countries have high production costs and have begun to turn to China for purchases, but at present China's output is very low and cannot meet the requirements of foreign businessmen.

In China, freeze-dried shallots, carrots, strawberries, ginseng, deer blood, and beef have been put on the market. With the improvement of people's living standards and the acceleration of the pace of life, the demand for freeze-dried food in the domestic market will increase day by day.
