Food heavy metal detection device and method thereof

Abstract

The invention discloses a food heavy metal detection device which comprises a workbench, the upper end face of the workbench is fixedly connected with a crushing box, and a driving mechanism for driving a first rotating shaft and a first gear to rotate synchronously is arranged below the workbench; the detection method of the food heavy metal detection device comprises the following steps: S1, adding food and reagents; s2, starting the equipment; s3, carrying out a reaction; s4, comparing and identifying. According to the food crushing device, the driving mechanism drives the separation disc to rotate and drives the through hole to rotate to the position below the discharging opening of the crushing box and stop, food enters the through hole, meanwhile, the rotating disc rotates to drive the vacant comparison pipe to rotate into the notch, the food in the through hole falls into the comparison pipe, and meanwhile, the contact block rotates, so that the control valve is opened; a color developing agent in the reagent tank drips into the comparison tube filled with the food, so that the color developing agent can be in full contact with the food due to a relatively small food sample, and the detection accuracy is relatively high.

Description

technical field [0001] The invention relates to the technical field of food heavy metal detection, in particular to a food heavy metal detection device and a method thereof. Background technique [0002] Food, soil, and water quality are gradually polluted by industrial waste gas, waste water, and waste residue, resulting in the accumulation and accumulation of heavy metals such as cadmium, copper, arsenic, chromium, mercury, nickel, iron, aluminum, zinc, manganese, and copper in the soil cultivation layer , especially in the suburbs of cities, the phenomenon is even more serious; coupled with the massive use of inorganic chemical pesticides, etc., the heavy metal content in vegetables and fish has seriously exceeded the standard, and it continues to accumulate in the human body, leading to the occurrence of chronic heavy metal poisoning in consumers. Some additives are often added during processing, and some heavy metals inevitably exist in the additives, such as common lea...

Problems solved by technology

[0003] Excessive intake of heavy metals will cause great harm to the human body. In order to keep the content of heavy metals in food at a safe level, it is often necessary to detect the content of heavy metals in food. The detection of heavy metals mainly uses heavy metals that can react with color reagents. When combined together, a colored liquid will be produced. Generally, the stronger the color of the liquid, the higher the heavy metal content; but the main edible part of the food will absorb a large amount of color developer. When the color developer drops into After the food is soaked, it cannot evenly penetrate all the food. Therefore, a food heavy metal detection device and method are proposed.
