Pretreatment device for food detection

Abstract

The invention discloses a pretreatment device for food detection. The pretreatment device for the food detection comprises a tank body, wherein a crushing grinding barrel is arranged inside the tank body; crushing blades are arranged inside the crushing grinding barrel; the crushing blades are fixedly connected with a moving sleeve; the moving sleeve is provided with a grinding plate below the crushing blades; the tank body is provided with a material guiding plate below the crushing grinding barrel; the tank body is provided with a material drawer below the material guiding plate. Through arrangement of the moving sleeve, a lifting plate, a transmission rod and a crankshaft, the moving sleeve moves up and down during rotation so as to drive the grinding plate and the crushing blades to rotate and move up and down to sufficiently crush and grind a food sample, so that the pretreatment efficiency is improved, the food sample meets detection requirements, and the detection efficiency isimproved; through arrangement of the crushing grinding barrel in transverse reciprocating movement, no dead corner exists during crushing and grinding, sieve hole blockage is avoided, and the discharging speed is increased.

Description

technical field [0001] The invention relates to the field of food safety detection, in particular to a food detection pretreatment device. Background technique [0002] Food safety testing is to detect harmful substances in food according to national indicators, mainly the detection of some harmful and toxic indicators, such as heavy metals, aflatoxins, etc. An important aspect of food science and engineering is the introduction and application of chemical unit operations, and the development of food engineering unit operations, thereby promoting the development of the food industry in the direction of large-scale, continuous and automated. [0003] When testing food raw materials, it is necessary to prepare samples. For some solid block samples, grinding is required so that the samples can be put into the testing instrument or speed up the dissolution. The traditional grinding method is manual grinding through the grinding tank, which is laborious and efficient. Low, espec...

[0003] When testing food raw materials, it is necessary to prepare samples. For some solid block samples, grinding is required so that the samples can be put into the testing instrument or speed up the dissolution. The traditional grinding method is manual grinding through the grinding tank, which is laborious and efficient. Low, especially in the process of repeated testing of large batches, manual grinding cannot meet the requirements of testing, and an efficient food pretreatment device is needed
