Freeze dryer is a device used to freeze liquid materials and dry them under reduced pressure, mainly used in the fields of food, medicine, biological products, etc. It can handle various types of materials, including but not limited to the following:

Chemical raw materials: Freeze dryers can also process some chemical raw materials, such as dyes, resins, etc. Through the process of freezing and drying, chemical raw materials can be transformed into powder or granular form, which is convenient for subsequent processing and application.

Biological products: Freeze dryers can also process some biological products, such as cell cultures, enzymes, etc. By freezing and drying, biological products can be stored in a stable state, extending their shelf life, and reducing degradation and denaturation during transportation and storage.

Food materials: The freeze-drying machine can be used to process various foods, such as fruits, vegetables, meat, dairy products, seafood, etc. Through the process of freezing and drying, the moisture in food can be removed, the shelf life of food can be extended, and the nutritional content and taste of food can be maintained.

Pharmaceutical raw materials: Freeze drying machines are also widely used in the pharmaceutical industry, which can process various pharmaceutical raw materials, including chemical drugs, Chinese herbal medicine, etc. Through the process of freezing and drying, pharmaceutical raw materials can be transformed into powder or granular form, facilitating subsequent pharmaceutical processing.

In summary, freeze-drying machines can handle various types of materials, covering multiple fields such as food, pharmaceuticals, biological products, chemical raw materials, etc., providing convenient and fast drying solutions for various industries.
