Zusammenfassung: | The utility model relates to the technical field of drying for eliminating liquid from solid materials or products, and discloses a vacuum freeze drying experiment machine which comprises a main body, a glass cover is arranged on the main body, two supporting blocks are fixedly connected to the upper surface of the main body, the cross section of each supporting block is in an n shape, and the two supporting blocks are the same in structure and are arranged in a mirror image mode. The outer surface of the glass cover is fixedly connected with fixing blocks, the opposite outer surfaces of the two fixing blocks are fixedly connected with two rotating balls, according to the vacuum freeze-drying experiment machine, the motor is started to drive the glass cover to move up and down so that the main body can be opened and sealed through the glass cover, experimenters do not need to carry the glass cover, manpower is saved, and the experiment efficiency is improved. And moreover, the main body and the glass cover ar |
