Description

Technical Field

[0001] This utility model relates to the field of food crushing and sampling technology, and more specifically, to a food crushing and sampling machine used in food testing. Background Technology

[0002] Food pulverization sampling is a crucial step in the food testing process. It involves pulverizing raw food samples using specific equipment and methods to obtain representative, homogeneous samples for analysis. Pulverized samples have smaller particles and a larger surface area, allowing for better contact and reaction with reagents during testing, thus improving the sensitivity and accuracy of the detection method. For example, when testing for trace elements in food, pulverized samples dissolve more completely in the reagent, resulting in test results that more accurately reflect the actual content of the elements in the food.

[0003] A search revealed Chinese patent CN222419718U, which discloses a food crushing and sampling machine for food testing. This machine uses a food slicing structure to first cut the food into multiple slices. When these slices fall into the crushing chamber, they are crushed by the crushing rollers, reducing the load on the rollers and extending the machine's lifespan. The crushed material falls onto a filter screen below. If the food particles are still too small to pass through the filter, rotating blades in a material lifting structure lift them upwards. These lifted particles then fall back between the two crushing rollers for further crushing until they are small enough to pass through the filter. This structure ensures that the food particles entering the crushing chamber are of a substantially uniform size.

[0004] When the above-mentioned crushing and sampling machine is in use, the rotating motor drives the crushing wheel to rotate and crush the food particles. Then, the rotating drive motor lifts the incompletely crushed food particles that fall on the filter screen back up. Finally, the vibration of the vibrator can reduce the accumulation of food particles on the filter screen. The machine crushes and samples food through a series of drive devices. It has a complex structure and high operating cost. Utility Model Content

The vertical cylinder 3 is fixedly connected to the outside of the crushing cylinder 1. A rotating assembly 5 is provided on the grinding head 11. The rotating assembly 5 includes a stepper motor 501, a first rotating shaft 502, and an adjustable extension... The components include a shrink plate 503, a spiral rod 504, a toothed belt 505, and a second rotating shaft 506. The output shaft end of the stepper motor 501 is fixedly connected to the first rotating shaft 502. The bottom end of the first rotating shaft 502 is fixedly connected to the adjustable telescopic plate 503, and the first rotating shaft 502 is movably connected to the top end of the crushing cylinder 1 through a bearing. The bottom end of the adjustable telescopic plate 503 is fixedly connected to the grinding head 11.

[0027] Furthermore, the second rotating shaft 506 is movably connected to the top of the vertical cylinder 3 via a bearing, and the second rotating shaft 506 is connected to the first rotating shaft 502 via a toothed belt 505. A U-shaped plate 4 is fixedly connected to the top of the crushing cylinder 1, and the top of the U-shaped plate 4 is fixedly connected to the stepper motor 501. A filter screen 12 is fixedly embedded in the inclined tube 2, and a discharge pipe 9 is provided at the bottom of the filter screen 12, and the top of the discharge pipe 9 is fixedly connected to the inclined tube 2.

[0028] Furthermore, a support frame 8 is fixedly connected to the bottom end of the crushing cylinder 1, wherein the support frame 8 can support the crushing cylinder 1.

[0030] Furthermore, the bottom of the vertical cylinder 3 is threadedly connected to a threaded cap 7, which facilitates the removal of debris from inside the vertical cylinder 3.

[0031] The process involves opening the cylinder cover 6 and inserting a wrench into the grinding cylinder 1.

The stepper motor 501 is started, and its operation drives the first rotating shaft 502 to rotate, which in turn drives the adjustable telescopic plate 503 and the grinding head 11 to rotate. The grinding head 11 and the guide hopper 10 work together to grind and crush the food. The crushed food enters the inclined tube 2. Food scraps that meet the standard pass through the filter screen 12 and enter the discharge pipe 9. Larger food scraps enter the vertical cylinder 3 through the inclined tube 2. At the same time, the first rotating shaft 502 drives the second rotating shaft 506 to rotate through the toothed belt 505, which in turn drives the screw rod 504 to rotate. The screw rod 504 conveys the larger food scraps and allows them to re-enter the grinding cylinder 1. The structure is simple and effectively reduces the cost of use.
