What is the Home Freeze Dryer?

The home freeze dryer is small in size, simple in operation, and cost-effective; it is suitable for household and personal use, as well as for the research and development of new products in food factories.

Home freeze dryer can be used for fruits and vegetables to preserve their original nutrients to a large extent; it can also be used for seafood, meat, Chinese medicinal materials, etc.

What is a Freeze Dryer?

A freeze dryer is one of the most common and essential drying equipment, which is used to dry food ingredients by utilizing the freeze drying method.

It usually consists of four components, including a drying chamber, a vacuum pump, a heat source and a condenser.

Freeze dryer can be divided into commercial, laboratory, industrial, and household. It is widely used in food, pharmaceutical and other industries.

Freeze Drying Technology

Freeze drying is based on the process of removing water or other solvents from frozen biological products by sublimation.

Sublimation refers to the process in which a substance changes directly from a solid state to a gas state without going through a liquid state. Freeze-drying technology can preserve the integrity of the product’s biological, chemical structure and activity.

Freeze Drying is used for

The vacuum freeze dryer is suitable for the drying of materials, such as high-end raw materials, Chinese herbal medicine, biological, wild vegetables, dehydrated vegetables, food, fruits, chemicals, pharmaceutical intermediates, etc.

Freeze Dryer Application

The vacuum freeze dryer is suitable for the drying of materials, such as high-end raw materials, Chinese herbal medicine, biological, wild vegetables, dehydrated vegetables, food, fruits, chemicals, pharmaceutical intermediates, etc.

Drying is one of the methods to keep the substance undamaged. There are many drying methods, such as sun-drying, boil-drying, drying and so on. But these methods are all carried out at a temperature above 0°C. The product obtained by drying will shrink in volume and harden in texture. Most of the volatile components will be lost, and some heat-sensitive substances such as protein and vitamins will be denatured. Therefore, the properties of the dried product are quite different from those before drying.

Different from the above drying methods, freeze-drying technology is the best way to dry materials. The drying of the product is basically carried out at a temperature below 0°C. Freeze-drying technology is particularly suitable for many heat-sensitive substances. For example, proteins and microorganisms will not be denatured or lose their biological vitality. Therefore, it is widely used in medicine.
