Commercial Freeze Dryer Machine

Commercial vacuum freeze-dryer machine also named at small freeze dryer mini vacuum lyophilizer, also known as aerospace freeze-drying technology, it can be used for freeze drying various of food, fruit, vegetables and so on. Refers to a technology that uses the sublimation principle under the low-temperature vacuum state of about minus 30-50 degrees to make the water in the pre frozen food sublimate into water vapor without melting the ice, so as to dry the food.

Application range: fruits, vegetables, foods, milk powder, ice cream, instant drinks, flowers, poultry meat, pharmaceutical, Chinese herbal medicine, tonic and so on.

1. Compared with air drying, dehydration and other process technologies, the biggest characteristic of freeze-dried food is that it retains the color, fragrance, taste, shape of the product and the original nutritional composition of ecological food.

2. Touch screen operation, one-button start, automatic controller of freeze-drying process, easy and convenient. Perfect appearance, compact size;

3. Key components is imported brands, small noise, large capacity, high quality and stable freeze drying performance; Fast defrosting technology, over temperature automatic protection.

4. Transparent plexiglas door for easy observation of material commercial freeze drying machine process. There’s self-setting and real-time adjustment for the freeze-drying process, showing freeze-drying data and freeze-drying curves.

The lyophilization process can be divided into three stages: freezing, sublimation and analytical drying. Each stage has corresponding requirements, different materials have different requirements.

Freezing stage Freeze-drying first freezes the raw material so that the water in the raw material becomes ice, ready for the next stage of sublimation. The freezing temperature and freezing speed are the key to control, the temperature should reach the freezing point of the material below, the freezing point of different materials is different. The freezing speed is directly related to the size of ice crystal particles in the material, and the size of ice crystal particles is directly related to the structure and sublimation rate of solid materials. Under normal circumstances, 1-3 hours to complete the freezing of the material, into the sublimation stage.

We also have big scale commercial automatic freeze dryer vacuum lyophilizer machines can be chosen by customer needs, which is suitable for applying in food processing factory.
