Freeze-dryer, also known as freeze-dryer, is an efficient and advanced equipment. Through freezing and vacuum evaporation technology, substances are directly transformed from solid to gas, while maintaining their original shape and chemical properties. This technology has been widely used in many fields, especially in the food and pharmaceutical industries. It is well-deserved to freeze these materials with a freeze dryer with such characteristics!
Because the residual moisture of the dried material is very low, it can be stored for a long time at room temperature if the moisture-proof packaging is excellent. This is especially important for foods and medicines that need to be preserved for a long time.
Wide scope of application: freeze-drying equipment can be classified into pharmaceutical freeze-drying equipment and food freeze-drying equipment according to the different materials processed. Most medical equipment is box-shaped drying room, and shelves are arranged inside to support materials; The equipment used for food may be box-shaped or cylindrical. According to the type of food, it is selected to be frozen in the pre-cold storage or directly put into the drying room for drying.
High efficiency and energy saving: the heating and cooling system of the equipment can accurately control the temperature to ensure the uniform drying of materials. At the same time, the thermal efficiency of drying process can be greatly improved by improving heat preservation, preventing hot air leakage, adopting partial waste gas circulation and recovering waste hot gas.
The freeze dryer can handle a wide variety of materials, including but not limited to:
Fruits: bananas, apples, strawberries, yellow peaches, durians, etc.
Vegetables: mushrooms, peppers, ginger and garlic, carrots, etc.
Meat: chicken, duck, pork, beef, mutton, etc.
Instant foods: instant freeze-dried noodles, boxed light meals, baby food, tourist food, military food, etc.
Condiments: soup, jam, spices, etc.
Beverages: instant freeze-dried coffee, instant tea, etc.
Chinese herbal medicines: biological products such as ginseng, Cordyceps sinensis and yam.
Nutritions: honey, royal jelly, soft-shelled turtle, turtle, etc.
Seafood and aquatic products: fish, shrimp, sea shrimp, kelp, sea cucumber, oysters, shellfish, etc.
Freeze-dryer can be widely used in many fields, mainly due to its unique equipment characteristics:
Keep the material structure: because the material is dried in the frozen state, the water is directly sublimated into water vapor in the state of ice, so the physical structure and molecular structure of the material change very little. This enables the dried material to maintain its original shape and properties, such as taste, nutrition and original taste.
Porosity remains unchanged: the porosity of the original structure of the dried material remains unchanged after water is removed. Therefore, if water or soup is added, the material can be basically completely restored to its original state before drying in a short time.
Intelligent operation: Modern freeze dryers are usually equipped with intelligent functions such as automatic drainage system, manual automatic mode selection, monitoring system, freeze-drying process recipe storage function and PC remote monitoring system. These functions make the operation of the equipment more convenient and efficient, and also improve the safety and reliability of production.
To sum up, freeze dryer plays an important role in food and pharmaceutical industries with its unique equipment characteristics and wide application range. By controlling the temperature accurately, keeping the material structure, improving the storage stability and intelligent operation, it is well-deserved to freeze these materials with such characteristics. Freeze dryer provides an efficient, convenient and reliable solution for material handling.
