A food heavy metal detection device and detection method thereof

Abstract

The technical field of the detection equipment of the present invention relates to a food heavy metal detection device and its detection method, including: (1) put the food sample in the mixing and crushing frame, add an appropriate amount of water, adjust the motor speed to fast, turn on the motor to crush the food and mix it with Mix with water; (2) Place the sampling tube on the discharge end of the discharge joint, adjust the motor speed to slow rotation, slowly add water from the inlet tube until the weight of the mixing and crushing frame is greater than the elastic force of the elastic part, and the sampling tube starts Receive the liquid; (3) After the sampling tube has finished sampling, stop adding water to the liquid feeding tube; (4) Use a pipette gun to take the liquid in the sampling tube into the detection tube and place it in the detector for detection. The detection device has an ingenious structural design, which integrates multiple functions, and can realize the functions of food crushing, mixing, filtering, sampling and detection, greatly reducing labor costs; Convenient, high sampling accuracy.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a food heavy metal detection device and a detection method thereof. Background technique [0002] Heavy metals in food are very bad. After many heavy metals enter the human body through food, they will seriously damage human health. Therefore, it is necessary to detect heavy metals in food to help people improve awareness of prevention, food safety and environmental protection, and provide good protection for people's health and social environment. [0003] The detection of heavy metal content in food usually includes the following steps: crushing the food to be tested, adding water, mixing uniformly, soaking, stirring, filtering, sampling liquid, and testing. In the above steps, except for the final detection, each of the previous sampling steps requires manual operation, which is time-consuming and labor-intensive, and the accuracy is not good. At present, there ...

Problems solved by technology

In the above steps, except for the final detection, each of the previous sampling steps requires manual operation, which is time-consuming and labor-intensive, and the accuracy is not good

At present, there are some crushing and stirring devices that can realize the mixing of food and water. However, because the sample liquid required for detection is very small, the crushing and stirring devices in the prior art cannot perform quantitative sampling, and the amount of each sample is large, resulting in waste. , or the operation is also very cumbersome
