Description

Technical Field

[0001] The utility model relates to the technical field of food inspection equipment, in particular to a food inspection and testing sample preparation and stirring device. Background Art

[0002] Food inspection in a broad sense refers to a discipline that studies and evaluates food quality and its changes. It is based on some basic theories and various technologies of physics, chemistry, and biochemistry, and in accordance with established technical standards, such as international and national food hygiene / safety standards, to inspect the quality of food raw materials, auxiliary materials, semi-finished products, finished products, and by-products to ensure that the product quality is qualified. The content of food inspection includes sensory testing of food, testing of nutrients, additives, and harmful substances in food, etc.

[0003] When people test food, they usually mix the food sample with the test solution, and then test it through the testing equipment. In order to fully mix the sample and the test solution, people will stir them through a stirring device. During the stirring process, part of the sample may adhere to the inner wall of the stirring barrel, which will lead to an increase in the error of subsequent test data, which will not only make people's testing work more difficult, but also increase people's cleaning workload. Utility Model Content

[0006] Preferably, the stirring plates are processed with through holes, which penetrate the stirring plates, and the side of the scraper away from the stirring plates is in contact with the inner wall of the stirring barrel, so as to facilitate the flow of samples during stirring and enable the scraper to scrape off the samples on the inner wall of the stirring barrel.

[0007] Preferably, the outer wall of one end of the mixing barrel close to the top plate is processed with threads, and the side of the top plate close to the base is processed with threaded holes, so as to facilitate the connection of the mixing barrel with the top plate.

[0008] Preferably, a plurality of first elastic components are connected between the clamping block and the side plate, and a side of the clamping block close to the mixing barrel is processed into an arc surface, so as to further reinforce the mixing barrel and improve the stability of the mixing barrel.

[0009] Preferably, a second elastic component is provided inside the groove, and one end of the second elastic component away from the groove is connected to the support plate; the mixing barrel is supported from the bottom, so that people can install and disassemble the mixing barrel easily.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: by installing a detachable scraper on one side of the stirring plate, the stirring plate can scrape off the sample attached to the inner wall of the stirring barrel during the stirring process, preventing people from making excessive errors in the subsequent detection process, and improving the accuracy of the detection. After the use of the stirring barrel, the workload of people in cleaning is reduced, the cleanliness of the internal environment of the stirring barrel is improved, and people are more relaxed during the cleaning process. Since the scraper needs to rub against the inner wall of the stirring barrel frequently, the scraper can be limited by the cooperation of the limiting member and the limiting groove, which makes it more convenient for people to replace the scraper and improves work efficiency during the detection process.
