[0002] A key step in food testing is sample preparation. We need to prepare block or granular food into uniform powder according to the requirements of the corresponding test method, and then carry out sample pretreatment, sample testing and other links. Therefore, it is very important to use grinding equipment to grind food samples, which directly affects the uniformity and representativeness of samples in subsequent inspection links and the accuracy of test results.

[0003] The above device does not have a structure for quantitatively taking out the ground food powder when in use, so that when the existing grinding equipment is used, most of the food is directly placed in the grinder to be prepared into powder, and then the cover is opened to take it out. During the process of opening the cover, a large amount of powder will float out, and the external air or dust can easily contaminate the food powder in the grinder, which is inconvenient to use. Based on the deficiencies of the existing technology, the utility model designs a grinder. Utility Model Content
