Description

Technical Field

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

[0002] Food safety means that food is non-toxic and harmless, meets the necessary nutritional requirements, and does not cause any acute, subacute or chronic harm to human health. Food safety is a public health issue that affects human health due to toxic and harmful substances in food. Food safety is also an interdisciplinary field that specifically explores how to ensure food hygiene and food safety during food processing, storage, and sales, reduce disease risks, and prevent food poisoning. Therefore, food safety is very important.

[0003] At present, the existing sample crushing devices for food safety testing mostly only perform simple crushing when crushing food, and do not have the function of grinding and crushing. The crushed food also needs to be screened, which results in a small amount of screened food powder, which is not conducive to testing. For this reason, we propose a sample crushing device for food safety testing. Utility Model Content

[0006] Preferably, crushing rollers in contact with each other are arranged on both sides of the interior of the crushing box, and both ends of the crushing rollers are movably connected to the inner walls on both sides of the interior of the crushing box through bearings.

[0007] Preferably, a pulverizing motor is provided on one side of the exterior of the pulverizing box, and the pulverizing motor transmits power to the two pulverizing rollers via two mutually meshing transmission gears.

[0008] Preferably, a collecting bin is provided at the bottom end of the box body, a collecting trough is provided inside the collecting bin, the outer periphery of the collecting trough is slidably connected to the inner wall of the collecting bin, and the bottom of the conveying grinding trough extends to the top wall of the collecting bin.

[0009] Preferably, a screen is provided at the inner top of the collecting trough, and the screen is slidably installed on the inner top of the collecting trough through a slide groove provided on the outer side of the collecting trough.

[0010] Preferably, a feed opening is provided on the top of the pulverizing box, and the feed opening extends into the interior of the pulverizing box and is located directly above the two pulverizing rollers.

[0011] Preferably, a control panel is provided on an outer side of the box body, and the control panel is fixedly installed on the outer side of the box body by means of inlaying.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting a grinding roller inside the box, using the gradually narrowing gap between the grinding roller and the grinding groove, the food is ground into finer powder as the grinding roller rotates at a constant speed, thereby increasing the reaction rate during detection and increasing the amount of food powder that can be used for detection, so as to facilitate multiple detections.

[0014] 2. By using the guide hopper, the crushing box is connected to the grinding tank, so that the crushed food can be injected into the grinding tank for grinding, and the screen at the top of the collecting tank is used to screen the ground food powder to obtain finer food powder, thereby increasing the detection rate.
