Food drug residue sampling device

Abstract

The invention discloses a food and drug residue sampling device and relates to the field of food sampling equipment. The device comprises an inner cylinder, and an outer cylinder sleeves the outer surface of the inner cylinder. A second threaded part is fixedly arranged at the bottom end of the inner cylinder; the inner cylinder is in threaded connection with an end seat through the second threaded part, the inner side wall of the end seat is provided with a first threaded part in threaded fit with the second threaded part, a solid sampling rod is vertically arranged in the inner cylinder, andthe inner cylinder is fixedly connected with a solid sampling rod through a detachable mechanism; the detachable mechanism comprises a main shaft connected with a driving assembly. The whole samplingdevice is simple in structure, convenient to disassemble and assemble, beneficial to replacement and cleaning of the inner cylinder and the sampling rod, and capable of avoiding pollution of the sampling device to a to-be-detected sample and guaranteeing the accuracy of a food and drug residue detection result; and compared with a disposable sampling device, the disclosed device is capable of being repeatedly used, thereby lowering the detection cost.

Description

technical field [0001] The invention relates to the field of food sampling equipment, in particular to a food drug residue sampling device. Background technique [0002] With the improvement of people's living standards and consumption levels, the issue of food safety has attracted more and more consumers' attention. Among them, the problem of drug residues in food is a serious food safety issue. Modern livestock and poultry production Antibiotics are commonly used in planting and planting. In agricultural production, antibiotics can prevent and control pests, stimulate plant growth and increase production, resulting in antibiotic residues in food. Eating food containing drug residues has affected human health. The great harm has attracted the attention of countries all over the world. Therefore, the drug residues in food must be tested to ensure food safety. [0003] The determination methods of food and drug residues are roughly divided into three categories: microbial de...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the embodiment of the present invention provides a food and drug residue sampling device. Through the set detachable structure, the whole sampling device is divided into three parts: the inner cylinder, the outer cylinder and the end seat. The structure is simple, and the gap between the three The structure can be disassembled and assembled. The solid sampling rod installed in the inner cylinder through the snap-in structure can realize the sampling operation of the solid food to be tested under the drive of the driving component. The structure of the entire sampling device is simple and easy to disassemble. It is conducive to the replacement and cleaning of the inner cylinder and the sampling rod, which can avoid the contamination of the sample to be tested by the sampling device, and ensure the accuracy of the test results of food and drug residues. Compared with the disposable sampling device, it can be reused, which can reduce the cost of testing. Solve the problem that the existing sampling device dedicated to food testing needs to be cleaned after sampling, but due to its complex structure, it is inconvenient to disassemble and assemble, resulting in the growth of microorganisms inside the sampling device, resulting in the contamination of the sample. At the same time, compared with the disposable sampler, Although it can reduce the cost of testing, the use of disposable consumables is relatively large, resulting in an increase in the workload of subsequent processing
