Crushing device for food detection based on chromatographic analysis method

Abstract

The invention belongs to the technical field of food detection, and particularly relates to a crushing device for food detection based on a chromatographic analysis method. In allusion to the problems that a crushing device in traditional food detection is generally relatively simple in structural design, relatively single in operation mode of a crushing mechanism and common in crushing effect, the invention proposes the following scheme: the crushing device comprises a main body, the top end of the main body is fixedly provided with a top end cylinder, the top end of the top end cylinder is rotatably connected with a double-layer rotating cylinder through a bearing, the bottom end of the double-layer rotating cylinder is welded with a bottom bag, and the double-layer rotating cylinder and the bottom pocket are provided with material ports which are distributed at equal intervals. By means of a rotating motor, the main rod is driven to rotate, meanwhile, the double-layer rotating cylinder and the main rod can be driven to rotate oppositely through the transmission effect of a belt, a transmission rod, a transmission gear and a driven outer gear ring, a sample material is conveyed and extruded to a bottom bag through a spiral material pushing piece with a spiral bottom blade at the bottom end, and the food sample material is extruded, ground and crushed in cooperation with the triangular teeth.

Description

technical field [0001] The invention relates to the technical field of food detection, in particular to a food detection crushing device based on chromatographic analysis. Background technique [0002] As a method of separating and analyzing substances according to the difference in partition coefficient between the stationary phase and the mobile phase, chromatographic analysis is also widely used in food safety testing. Food safety refers to food that is non-toxic and harmless, meets proper nutritional requirements, and does not cause any acute, subacute or chronic harm to human health. Food safety testing is to detect harmful substances in food according to national indicators, mainly the detection of some harmful and toxic indicators, such as heavy metals, aflatoxins, etc. With the development of society, people's requirements for quality of life are getting higher and higher, so food safety issues also need to be paid more attention to.

AI Technical Summary

Problems solved by technology

[0003] In the process of food detection by chromatographic analysis, it is necessary to crush solid food samples. The general structure design of the crushing device in traditional food detection is relatively simple, the crushing principle is relatively simple, and the operating mode of the crushing mechanism is relatively simple. The crushing effect is average, and the crushed samples tend to have incomplete crushing parts, which will have a certain impact on the accuracy of the test results and have certain limitations.
