Embodiment

[0028] Example: such as Figure 1-5 Shown, a kind of sampling method that the present invention is used for food detection comprises the following steps:

[0029] Step 1: Put the sampling tube to be used in the sampling box, and when it needs to be used, install the sampling tube on the sampling tube to sample in batches;

[0030] Step 2: Through the air pump in the sampling cylinder, a negative pressure state is generated in the sampling cylinder, so that the food to be tested can be absorbed in the sampling tube;

[0031] Step 3: Take out the sampling tube from the sampling tube, and store it in the corresponding position of the sampling box, and use the temperature sensor at the bottom of the sampling box to detect the ambient temperature in the sampling box;

[0032] Step 4: Close the lid, manage the sampled food, and complete the sampling task;

[0033] The sampling device used in the present invention comprises a sampling cylinder 1, a sampling box 12, a heating base 1...

Abstract

The invention discloses a sampling method for food detection. The method comprises the following steps: 1, placing a sampling tube to be used in a sampling box, installing the sampling tube on a sampling cylinder when the sampling tube needs to be used, and sampling in batches; 2, generating a negative pressure state in the sampling cylinder through an air suction cylinder in the sampling cylinder to adsorb to-be-detected food in the sampling tube; and 3, taking out the sampling tube from the sampling cylinder, storing the sampling tube in a position corresponding to the sampling box, and detecting the environment temperature in the sampling box by using a temperature sensor at the bottom of the sampling box. According to the sampling method for food detection, by arranging the sampling box, the sampling cylinder and the sampling pipe, different foods can be sampled respectively, samples are stored in the different sampling pipes and cannot interfere with one another, the accuracy of later detection is guaranteed, the sampling pipe is fixed in the fixing cylinder of the sampling cylinder through the limiting rod, the sampling barrel can be repeatedly used, and only different sampling pipes need to be replaced.

Description

technical field [0001] The invention relates to the technical field of food sampling, in particular to a sampling method for food testing. Background technique [0002] 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. An important aspect of food science and engineering is the introduction and application of chemical unit operations, and the development of food engineering unit operations, thereby promoting the development of the food industry in the direction of large-scale, continuous and automated. With the improvement of people's living standards, people's The concept has changed from how to eat well to how to eat well and safely, so food quality and safety are getting more and more attention. However, food safety problems such as various pathogenic bacteria, pesticide residues, antibiotics and biological toxins in food have frequ...
