Multifunctional food sample detecting vehicle

Abstract

The invention relates to a multifunctional food sample detecting vehicle, which comprises a vehicle end and a passenger compartment that are based on an overall design. The vehicle head is arranged atthe left side of the passenger compartment. Double doors are arranged at the front side of the passenger compartment. A food sample refrigerating storage device (1), a collection eluent sample device(2), an ash sample test device (3) and a flue gas sample test device (4) are arranged in the passenger compartment. On the basis of improvement, the multifunctional food sample detecting vehicle hasadvantages of reasonable structure, small occupied space, great convenience and high flexibility in use and is capable of storing various meat type samples in classes. The multifunctional food sampledetecting vehicle has characteristics of simple structure, great convenience in operation, great easiness in sample liquid collection, high recyclability, and high use reliability and is convenient todismount. The vehicle can be dismounted with less effort and time and is convenient to replace. The vehicle having a simple structure is used conveniently and reliably; the lamp body is convenient toreplace; and various heavy metal materials can be detected conveniently.

Description

technical field [0001] The invention relates to the field of food sample detection, in particular to a multifunctional food sample detection vehicle. Background technique [0002] Meat food refers to the most important class of food in the human diet. Its raw materials are edible meat and some other tissues of various animals, which are processed to different degrees and methods to become different types of meat food. Common meats include pigs, cattle, sheep, chicken, etc. In order to ensure food safety, sampling and testing of meat products is required. [0003] In the sampling and testing of meat products, in order to reduce the sample matrix interference and improve the detection sensitivity, solid phase extraction is usually used to selectively elute the sample to achieve the separation, purification and enrichment of the sample. When collecting and preparing eluent samples, it is necessary to pass the liquid sample solution through the adsorbent to retain the substan...

AI Technical Summary

Problems solved by technology

At present, the storage of meat samples generally uses refrigeration equipment similar to freezers, but most of these equipment are rectangular in shape, occupy a large area, have poor flexibility of use, and are inconvenient for the classification and storage of samples.

[0008] (2) Most of the existing adsorbents are filled in a syringe-shaped cylinder, which is supported and fixed in the cylinder by the sieve plates on the upper and lower sides. Due to the small pore size of the sieve plate, about 20 μm, the solvent cannot pass through the adsorbent quickly. , it is easy to stay above the sieve plate, so it is necessary to pressurize the cylinder to make the solvent pass through the adsorbent quickly

However, the existing pressurization method is relatively complicated, and additional inflatable equipment is required, which is inconvenient for the collection of eluent. In addition, most of the existing collection equipment are disposable, which causes serious waste and increases the detection cost.

[0009] (3) The structure of the existing ashing furnace is relatively fixed, and the heating element is fixedly connected to the furnace chamber. Once the heating element is damaged, it will be troublesome in the process of maintenance or replacement, and it is not convenient to disassemble the furnace body. Disassembly takes time and effort, and is inconvenient replace heating element

[0010] (4) The light source is an important part of the atomic absorption spectrometer. Generally, the hollow tube cathode lamp is used as the sharp line light source. The spectrum emitted by the hollow cathode lamp is mainly the spectrum of the cathode element, so different measured elements are used as the cathode material, but in In the actual measurement process, it is inevitable to measure different heavy metals. Therefore, the hollow cathode lamp of the corresponding element needs to be replaced every time an element is measured. At present, most of the replacement is done manually, which is not only time-consuming and laborious, but also affects the detection efficiency.
