Drying in a vacuum, the raw material can be dehydrated at low temperatures and then transported to a freeze-drying chamber. In a vacuum, the temperature rises to tens of degrees, which promotes the direct sublimation of water in frozen foods. The lyophilized grain prepared by the lyophilized machine is a process of dewatering food under vacuum and in a very low temperature environment. Water can be converted directly from a solid to a gas without sublimating the liquid in between.

Compared with drying and puffing drying, freeze drying technology can retain as much as possible the color, aroma, taste and other nutrients in food, effectively prolonging the shelf life of food. Air dryer adopts large air volume freeze-drying machine, low noise fan to dry naturally, which can effectively remove water droplets on the surface of materials for drying.

The use of food lyophilizer has the following functions:

First, freeze-drying is carried out at low temperature, so it is especially suitable for many heat-sensitive substances. As or loss of biological vitality.

Two, when drying at low temperature, the loss of some volatile components in the material is very small, and the original nutrients are maintained.

Three, because in the frozen state of drying, so the volume is almost unchanged, maintain the original structure, no concentration phenomenon.

The freeze-drying machine has programmable heating and temperature control functions, and can view the freeze-drying curve, which is convenient for users to observe the freeze-drying process of fruits and vegetables. Compared with the pilot-scale freeze-drying machine with the same freeze-drying area, this product has the advantages of smaller volume and lower price. Compared with the traditional laboratory small lyophilizer, the product is easy to operate, freeze-drying in place, and avoids the pollution and manual operation in the material drying process.
