Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a food crushing and sampling device for food testing. Background Technology

[0002] Food testing is a crucial step in ensuring food safety and consumer health. The quality of sampling directly affects the accuracy of test results. To obtain representative samples, food usually needs to be pulverized to ensure uniform distribution of sample components. With the diversification of food types, existing sampling devices need to be able to adapt to different food types. Therefore, it is particularly important to develop an efficient, convenient pulverization and sampling device that can adapt to multiple food types.

[0003] A search revealed an existing patent (publication number: CN222689513U) that discloses a food testing crushing and sampling device, including a support leg. A frame is fixedly mounted on the top of the support leg. A bracket and a conveying cylinder are fixedly mounted on the top of the frame. A controller is fixedly mounted on the outer wall of the bracket. A sampling component is located at the bottom of the conveying cylinder. A fixed seat is mounted on one side of the outer wall of the frame, and a shell is mounted on the other side of the frame. The controller sends a signal to start the motor, which drives the drive wheel to rotate. The drive wheel then drives a rotating wheel via a first belt, which in turn drives a driven wheel via a second belt. This causes the rotating rod to drive multiple crushing rollers to crush the food against the inner wall of the crushing chamber. Because the crushing rollers are arranged in a serrated, alternating pattern on the inner wall of the crushing chamber, the food is crushed more thoroughly, resulting in a better crushing effect and solving the problem that existing devices often require secondary crushing.

[0004] However, in the actual use of the above-mentioned scheme, dust may be generated during the food crushing process. The above-mentioned equipment does not have a dust prevention function. The dispersion of dust may lead to a reduction in sample volume or uneven distribution, thereby affecting the accuracy and representativeness of the test results. Secondly, dust is prone to cross-contamination, especially when the equipment is used for different food samples, which further affects the reliability of the test. In addition, dust suspended in the air not only increases the health risks of workers, but may also bring safety hazards, especially when some food dust is flammable.

[0005] Therefore, this utility model provides a food crushing and sampling device for food testing. Utility Model Content

[0052] Specifically, when using this food crushing and sampling device for food testing:

[0053] First, the food is placed into the feeding hopper 2. At the same time, the first motor 11 drives the first crushing rod 12 to rotate, and the first crushing rod 12 drives the first transmission gear 13 to rotate synchronously. Then, the first transmission gear 13 drives the second crushing rod 15 to rotate in opposite directions with the first crushing rod 12 through the second transmission gear 14, thereby crushing the food. The crushed food falls into the collecting hopper 41, which collects the food. By pulling the handle 42 outward, the collecting hopper 41 is moved outward to facilitate the collection of the food.

[0054] During the process, the exhaust fan 24 collects the gas in the filter box 21 and sends it into the diversion box 23. Then, it is diverted through the first delivery pipe 25 and sent into the air outlet 26. The gas is then sprayed out at high speed through the air outlet 26 and then the airflow is guided into the filter box 21 for circulation through the air guide plate 22.

[0055] During the gas flow, the dust generated during the food crushing process is filtered through the filter screen 3. At the same time, the second motor 31 drives the cleaning blades 32 to rotate on the filter surface of the filter screen 3 to clean the filter surface. The cleaning blades 32 also push the dust to the second conveying pipe 27 and collect the dust through the collection bottle 28. After the collection bottle 28 is full, the collection bottle 28 is rotated to remove it and clean the dust inside.

[0056] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
