Description

Technical Field

[0001] The utility model relates to the technical field of food safety detection, in particular to a food safety detection sample preparation device. Background Art

[0002] Food refers to all kinds of finished products and raw materials for human consumption or drinking, as well as items that are traditionally both food and Chinese medicinal materials, but does not include items for therapeutic purposes. Food has two main functions for the human body, namely nutritional function and sensory function. Some also have a regulatory function. Nutritional function means that food can provide the nutrients and energy needed by the human body and meet the nutritional needs of the human body. This is the main function of food. Sensory function means that it can meet people's different hobbies and requirements, increase appetite and stabilize emotions. Food safety is a major basic livelihood issue that concerns every family and every person. Food testing can study and evaluate food quality and its changes. It is based on some basic theories and various technologies of physics, chemistry, and biochemistry. According to the established technical standards, the quality of food raw materials, auxiliary materials, semi-finished products, finished products and by-products is inspected to ensure that the product quality is qualified. Food testing requires the sample to be crushed and then diluted with solvent, and the test sample is extracted and placed in a special testing instrument to obtain the corresponding data. However, when preparing samples for food safety testing, the sample often needs to be processed outside the test container before testing. In the process of food from finished products to samples, it cannot be completely guaranteed that it will not be contaminated by the outside world. This has a certain impact on the test results and is prone to errors. Some integrated processing and sample preparation devices will also be exposed during the extraction process.

The utility model relates to the technical field of food safety testing equipment, specifically refers to a sample preparation device for food safety testing that has no direct contact with the outside world in all stages from raw materials to sample preparation, integrates and performs raw material loading in steps, is easy to handle the residues generated by sample preparation, and obtains more accurate test results.

[0004] However, in actual use of this patent, it is sometimes necessary to quantitatively control the food feed to avoid blockage and make the test results more accurate. Therefore, we need a food safety testing sample preparation device. Utility Model Content
