Portable food heavy metal detector

Abstract

The invention provides a portable food heavy metal detector, and relates to the technical field of food detection. The portable food heavy metal detector comprises a shell and a test tube, a gear motor is fixedly installed on one side face of the shell, an oval block is fixedly connected to the output end of the gear motor, a mouth-shaped block is arranged on the outer surface of the oval block, supporting rods are fixedly connected to the two side faces of the mouth-shaped block, two fixing blocks matched with the supporting rods are fixedly connected to the interior of the shell, and a pushplate is arranged in the mouth-shaped block. The portable food heavy metal detector is provided with the gear motor, the oval block, the mouth-shaped block, the supporting rods, the fixing blocks, a sliding rod, a clamping mechanism, a supporting plate and a spring, so the detector has the advantages of high automation degree, uniform mixing and stirring and high detection efficiency, and solves the problems of low detection efficiency and inaccurate detection result due to the fact that most of traditional detection modes adopt manual test tube holding for mixing and stirring and are prone touneven mixing.

Description

technical field [0001] The invention relates to the technical field of food detection, in particular to a portable food heavy metal detector. Background technique [0002] Food, soil, and water quality are gradually polluted by industrial waste gas, waste water, and waste residue. Some people even use industrial waste water to irrigate crops directly, resulting in cadmium, copper, arsenic, chromium, mercury, nickel, iron, aluminum, zinc, Manganese, copper and other heavy metals are enriched and accumulated in large quantities, especially in the suburbs of cities. In addition, the heavy metal content in vegetables and fish is seriously exceeded due to the extensive use of inorganic chemical pesticides, which continue to accumulate in the human body, resulting in consumption. The phenomenon of chronic heavy metal poisoning has occurred, and there have been many heavy metal collective poisoning incidents in China, which have aroused great attention from the government and wides...

AI Technical Summary

Problems solved by technology

[0003] Most of the detection methods of traditional food heavy metal detectors use the wet digestion method, which is to add an oxidizing strong acid to an appropriate amount of food samples, mix and stir, so as to destroy the organic matter, release the inorganic components to be tested, and form non-volatile inorganic compounds , for analysis and determination, but the traditional wet digestion method mostly uses manual holding of the test tube for mixing and stirring, the detection efficiency is low, and it is easy to mix unevenly, resulting in inaccurate detection results
