Description

Technical Field

[0001] The utility model relates to a pretreatment device for food detection, belonging to the field of food detection. Background Technique

[0002] Food safety detection is to detect harmful substances in food according to national standards, mainly the detection of some harmful and toxic indicators, such as heavy metals, aflatoxins, etc.

[0003] However, in the pretreatment operation of food, it is usually necessary to crush the food to be detected. When sampling and detecting food, samples are taken from different positions or different batches of the same food to improve the accuracy of detection.

[0004] In the prior art, when crushing food, referring to the patent document CN219369314U, the device proposed in this patent document drives the driving motor to drive the driving wheel and the driving belt to rotate, thereby driving the rotating shaft and the rotating blade to rotate. Under the action of centrifugal force, the contracted rotating blade unfolds, and the rotating blade cooperates with the inner blade to crush the food sample in the crushing cylinder. Under the action of the double blades, the food sample is quickly crushed. At the same time, multiple crushing cylinders are used for crushing. Although this device can crush multiple foods at the same time, it is not convenient for screening and filtering after crushing, and it is not convenient for subsequent detection work for materials with larger or smaller particles.

[0036] Working principle: When preprocessing food, by pouring the food into the box body 1, the food can enter the crushing area under the limitation of the feeding plate 4. By starting the first servo motor 201, the output rotating shaft of the first servo motor 201 drives a first rotating rod 202 to rotate. The first rotating rod 202 drives the first rotating rod 202 on the other side to rotate through the gear 203. And when the first rotating rod 202 rotates, it can crush the food through the crushing wheel 204. The crushed food will fall onto the filter plate 301 for filtering.
