The food freeze-drying machine consists of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. The main components of the food freeze-dryer are drying oven, condenser, freezing unit, vacuum pump, heating/cooling device and so on. The principle of the food freeze dryer is to freeze the items to be dried to below the triple point temperature, and then vacuum the solid water (ice) in the items to directly sublimate into water vapor, remove from the items, make the items dry. After the material is pre-treated, it is sent to a quick-freezing chamber for freezing, then sent to a drying warehouse for sublimation and dehydration, and then packaged in a post-processing workshop. The vacuum system establishes a low pressure condition for the sublimation drying chamber, the heating system provides the sublimation latent heat to the material, and the refrigeration system provides the required coldness to the cold trap and the drying chamber. The equipment adopts high-efficiency radiant heating, the material is heated evenly, adopts high-efficiency catching cold trap, and can achieve rapid defrosting; adopts high-efficiency vacuum unit and can realize oil-water separation; adopts parallel centralized refrigeration system, multi-channel on-demand cooling, working conditions Stable and energy-saving; artificial intelligence control, high control accuracy, easy operation....
It is well known that when using a freeze dryer for the first time, we must thoroughly clean all parts of the dryer. Everyone knows that stainless steel parts are cleaned with ethanol, and organic glass is cleaned with normal saline. Ampoules are cleaned with an ultrasonic cleaner, but what do we need to do before we actually operate the freeze dryer?...

The introduction of the concepts of freeze-dry books usually mentioned, cooling rate, the greater the solution of supercooling degree and the greater the degree of supersaturation, the smaller the critical crystal grain size is, the faster the nucleation, easy to form fine crystal particles is more smaller. So after sublimation, formed in the material of pore size is small, the drying rate is low, but good water after dry compound; Slow freezing, on the other hand, tend to form larger particles of ice, ice sublimation after the formation of the water vapour to escape channel size is bigger, to improve the drying rate, but dry after water is poor....
