Food Lyophilizer Machine

Systematic research on freeze-drying of food began in the 1950s. In the 1960s, the world's freeze-dried food has developed by leaps and bounds. The United States, Japan, Germany, the Netherlands, Denmark and other countries have successively established their own food freeze-drying factories. At that time, among all freeze-dried foods that appeared in the European and American markets, coffee was the most successful product. In Japan, freeze-dried instant noodles accounted for half of its entire instant noodle market, becoming the driving force for the application of freeze-drying technology. From the 1970s to the 1990s, worldwide, freeze-drying technology was widely used in synthetic food, vegetables, shrimp, fried foods, meat sauce, matsutake mushrooms, fish, shellfish, meat processing and other industries.

The principle of Food Lyophilizer Machine

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 Food Lyophilizer Machine

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;
