Automatic pretreatment system and pretreatment method for food detection sample

Abstract

The invention belongs to the technical field of food detection, and particularly relates to a food detection sample automatic pretreatment system and a pretreatment method. The food detection sample automatic pretreatment system comprises a working platform used for supporting, wherein a shaking mechanism and a mounting plate are sequentially arranged above the working platform, mounting columns extending upwards are symmetrically arranged on the mounting plate, and a working barrel is arranged between the two mounting columns; an upper sealing disc and a lower sealing disc are arranged at the two ends of the working barrel in a threaded mode respectively, an extension column is arranged on the side, close to the mounting column, of the working barrel, a mounting shaft is rotationally arranged on the extension column and extends in the direction of the mounting column in a penetrating mode; a water supply mechanism for supplying water is arranged on the side, away from the working barrel, of one mounting column, a smashing mechanism for smashing food is arranged on the upper sealing disc, and a stirring mechanism for stirring the food is arranged on the lower sealing disc. The device can effectively realize automatic operation of crushing a to-be-detected food sample and adding water and stirring, and the pretreatment efficiency before food detection is improved.

Description

technical field [0001] The invention relates to the technical field of food testing, in particular to an automatic preprocessing system and a preprocessing method for food testing samples. Background technique [0002] Food safety is a discipline that describes the prevention of foodborne illnesses during food handling, processing, and storage. Food safety issues not only affect the life and property of the masses, but also restrict the economic development of the entire country. Food safety issues have aroused great concern, and food testing has become an indispensable process. [0003] Food needs to be sampled before leaving the factory, for solid food, such as biscuits and so on. The traditional food sample detection steps are as follows: First, randomly select a batch of food samples for testing, use a mortar to mash the food samples to be tested for later use, and then add an appropriate amount of water to the beaker containing the mashed food samples, And use a glas...

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the samples used for food testing are manually ground in the process of crushing, which is time-consuming and laborious; the process of adding water to the testing samples to make them dissolve and mix requires manual stirring with glass rods , which undoubtedly increases the labor intensity of the inspectors
