In this thesis, a new RNA grinding extraction system is designed and provided for the shortcomings of the existing RNA grinding extraction system technology. The designed RNA grinding and extraction system uses mechanical grinding to extract and extract RNA. This method eliminates the manual grinding operation process and simplifies the operation. At the same time, when the liquid nitrogen is passed in, it can avoid the limbs directly contacting the liquid. Nitrogen contact avoids frostbite of hands due to liquid nitrogen, which greatly improves safety, while mechanical grinding adopts rotary grinding, and the grinding parts are pushed by the cylinder, so that the grinding head of the grinding parts abuts the grinding groove, which is driven by the motor. When the grinding part rotates, it can fully contact the grinding tank to ensure the quality and efficiency of grinding.
