Abstract

The invention relates to the field of freeze dryers, in particular to a freeze dryer convenient to dewater, which comprises a main body, a drying chamber is arranged in the main body, a storage tray for placing articles is arranged in the drying chamber, the main body is provided with a vacuum pump, and a vacuum main pipe is arranged in the main body. The main vacuum pipe is connected to the air exhaust end of the vacuum pump, a branch vacuum pipe is arranged in the storage disc, articles placed in the storage disc are located on the periphery of the branch vacuum pipe, vacuum holes are formed in the branch vacuum pipe, and when the storage disc is placed in the main body, the branch vacuum pipe is connected with the main vacuum pipe. The solid-state water sublimation device has the effect of reducing the influence of object stacking on solid-state water sublimation.

Description

technical field [0001] The present application relates to the field of freeze dryers, in particular to a freeze dryer that facilitates dehydration. Background technique [0002] With the development of our society, people's requirements for food are getting higher and higher. They want the food to stay fresh and have a longer shelf life. Therefore, the market of freeze-dried food is developing rapidly, and freeze-dried food is usually made of freeze-dried food. It is made by freezing and drying food in a machine. [0003] The freeze dryer usually includes a drying box, a condenser, a freezing unit, a vacuum pump, a heating device and a cooling device. After the staff puts the food into the drying box, the temperature of the food is first lowered to the triple point through the freezing unit and the cooling device. Then, the food is heated by vacuum pump and heating device, so that the solid water in the food is directly sublimated into water vapor, and then the water vapor ...
