Food freeze dryer is a kind of equipment used for food processing, which can quickly freeze and sublimate the moisture in the food, so as to get dry food. Food freeze dryer plays an important role in the deep processing of agricultural products, it can quickly remove the moisture of agricultural products, prolong the shelf life of agricultural products, and improve the quality and taste of agricultural products.
First, the working principle of the food freeze dryer.
The working principle of the food freeze dryer is to use the refrigerant to quickly freeze the moisture in the food into ice crystals, and then sublimate the ice crystals into water vapor in a vacuum environment, so as to achieve the purpose of drying food. The food freeze dryer has the advantages of fast, energy-saving, environmental protection, etc., and it can be widely used in the processing of various foods.
Second, the application of food freeze dryer in the deep processing of agricultural products.
1.Fruit freeze-dried.
Fruit freeze-drying is one of the important applications of food freeze-dryer in the deep processing of agricultural products. Fruits processed by food freeze-dryers can maintain their original color, taste and nutritional value, while having a long shelf life. Freeze-dried fruit products can be used as snack foods or nutritional supplements.
2.Freeze-dried vegetables.
Vegetable freeze-drying is also a common application of food freeze-dryer in the deep processing of agricultural products. Vegetables processed by a food freeze dryer can maintain their original color and taste while having a long shelf life. Freeze-dried vegetable products can be used as convenience foods or nutritional supplements.
3.Meat freeze-dried.
Meat freeze-drying is also one of the applications of food freeze-dryer in the deep processing of agricultural products. Meat processed by a food freeze dryer retains its original taste and nutritional value while having a long shelf life. Freeze-dried meat products can be used as convenience foods or nutritional supplements.
3. Advantages of food freeze dryer.
1.Fast drying: The food freeze dryer adopts advanced refrigeration technology and vacuum technology, which can quickly remove the moisture in the food in a short time.
2.Energy saving and environmental protection: The food freeze dryer does not need a lot of heat and electricity during operation, and at the same time, it will not produce harmful substances, which meets the requirements of environmental protection.
3.Long shelf life: Food processed by a food freeze dryer has a long shelf life and can be stored for a long time without spoiling.
4.High taste and nutritional value: The food freeze dryer will not destroy the nutrients and taste in the food during the drying process, and can maintain the original quality of the food.
IV. Conclusions. Food freeze dryer plays an important role in the deep processing of agricultural products, it can improve the quality and taste of agricultural products, extend the shelf life of agricultural products, and provide a new solution for the processing and storage of agricultural products. With the continuous progress and application of science and technology, food freeze dryers will play a more important role in the deep processing of agricultural products.
