Food freeze dryer is a very important food processing equipment, which can effectively extend the shelf life of food, increase the added value of food, and is suitable for various food processing sites and food production enterprises. When using a food freeze dryer, it is necessary to strictly control the operating parameters, maintain equipment cleanliness and hygiene, pay attention to food quality and operational safety, in order to ensure the quality and stability of food freeze drying.

Food freeze dryers have a wide range of applications in food processing. It can extend the shelf life of fresh fruits, vegetables and other foods while maintaining their original taste and nutrition, making it very suitable for food preservation and portability. Secondly, food freeze-drying machines can also be used to produce various freeze-dried foods, such as freeze-dried fruits, freeze-dried meats, etc., which are convenient for consumers to consume.

What foods is the food freeze dryer suitable for?

Fruits: Various types of fruits such as apples, pears, strawberries, peaches, cherries, blueberries, raspberries, plums, etc. can be dried using a food freeze dryer to produce dried fruits, fruit powder, and other food products.

Vegetables: Carrots, green beans, corn, tomatoes, cauliflower, spinach, cauliflower, onions, and other vegetables can be processed using a food freeze dryer to produce dried vegetables, vegetable powder, and other food products.

Meat: Various types of meat such as beef, pork, chicken, lamb, and fish can be processed using a food freeze dryer to produce dried meat, meat floss, and other products.

Seafood: Various types of seafood such as shrimp, fish, shellfish, crabs, etc. can be processed by a food freeze dryer to make dried seafood, seafood crisps, and other foods.

Beans: Various types of beans such as soybeans, mung beans, red beans, black beans, and kidney beans can be processed by a food freeze dryer to produce dried beans, bean powder, and other food products.

Noodle products: Various noodle products such as bread, cookies, cakes, biscuits, instant noodles, etc. can be processed by a food freeze dryer to produce dried noodles, noodle slices, and other foods.

Dairy products: Various dairy products such as milk, yogurt, formula milk, cheese, butter, whey, etc. can be processed by a food freeze dryer to produce dried dairy products, dairy powder, and other food products.

The main components of a food freeze dryer include vacuum system, freezing system, sublimation system, heating system, etc. During the work process, first place the food in the freezer for freezing treatment, then introduce it into a vacuum environment, activate the heating system for sublimation treatment, and finally remove the freeze-dried food from the packaging for storage. The entire process requires strict control of parameters such as temperature, vacuum degree, sublimation speed, etc. to ensure the quality and stability of food freeze-drying.

The working principle of a food freeze dryer is to cool liquid food on a freezing plate, turning it into a solid state, and then place it in a vacuum chamber. Through low temperature and low pressure conditions, the water is directly sublimated from the solid state into gas, thereby achieving food freeze drying. This process ensures that the food is not damaged by high temperatures, preserving its nutritional value and taste.
