Sample pretreatment process for food detection

Abstract

The invention discloses a sample pretreatment process for food detection in the technical field of food detection. The sample pretreatment process comprises the following step of 1, putting food to bedetected into a crushing device in pretreatment equipment for pre-crushing. By means of the sample pretreatment process, through centrifugal force, the food which is not smashed thoroughly and has large particles can be isolated into an isolation area, the situation that the food with large particles blocks filtering holes in a separation plate can be avoided, and filtering of the food with smallparticles can be accelerated in the rotating, inclining and rebounding processes of the separation plate; and through rotation of a first cleaning rod and a second cleaning rod, the food with the large particles can be scraped on the separation plate, the separation process of the food with the large particles can be accelerated, the food with the small particles on the separation plate can be scraped through the first cleaning rod and the second cleaning rod, and the filtering process of the food with the small particles can be accelerated.

Description

technical field [0001] The invention relates to the technical field of food testing, in particular to a sample pretreatment process for food testing. Background technique [0002] Prospects for the food safety industry. At present, the food safety industry is facing opportunities for rapid development. First of all, food safety has become the focus of people's attention. From the experience of developed countries and regions, food safety problems are likely to occur when urbanization reaches a certain level. In recent years, many food safety incidents have occurred in China, which has aroused great concern from the people. , which provides an opportunity for the development of the food safety industry. Secondly, the development of the food safety industry has a favorable international environment, and food safety is a worldwide issue. [0003] In the prior art, operations such as pulverization, filtration, stirring, and mixing are generally used when food is pretreated. Af...

Problems solved by technology

[0005] The object of the present invention is to provide a sample pretreatment process for food testing, to solve the problems in the prior art proposed in the above background technology. When pretreating food, operations such as crushing, filtering, stirring, and mixing are generally used. , after the food is crushed, there will be food with large particles that have not been crushed thoroughly, and the food with large particles may accumulate on the top of the filter plate when filtering. The accumulated food with larger particles may block the filter holes, resulting in the food with smaller particles unable to fall from the filter holes, and it is not convenient to clean up the accumulated food during the filtering process. The problem that will lengthen the detection process
