Description

Technical Field

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

[0002] Food testing, as an important technical means to ensure food safety, focuses on the qualitative and quantitative analysis of key indicators such as nutritional components, additive content, and contaminant residues in food samples using scientific methods. Modern food testing technology encompasses various methods, including physicochemical testing, microbiological testing, and molecular biological testing. The testing process requires ensuring the representativeness and homogeneity of the samples, and the accuracy of the test results directly affects the conclusions of food safety risk assessment. With the continuous improvement of testing standards, the technical requirements for sample pretreatment are becoming increasingly stringent.

[0003] In a complete food testing process, sample pretreatment is a crucial step that determines the success or failure of the test. Among them, the crushing process directly affects the accuracy and repeatability of subsequent tests. Food samples need to be thoroughly crushed to achieve a homogeneous state, ensuring that each component can be evenly distributed in the test solution during testing. Especially for solid or semi-solid foods, the crushing effect is directly related to the solvent extraction efficiency. Uneven crushing will lead to deviations in test results. Therefore, modern food testing laboratories have placed higher demands on the performance of crushing equipment.

[0004] Traditional manual grinding methods rely mainly on simple tools such as mortars and pestles. Operators need to expend a lot of physical strength to perform repetitive grinding actions. This method has inherent defects such as low grinding efficiency, uneven particle size, and susceptibility to human error. Manual operation makes it difficult to ensure consistency between batches, and it is not effective for special ingredients with strong fibers or high viscosity. Furthermore, prolonged operation can easily lead to operator fatigue, which in turn affects the efficiency of subsequent testing. These limitations have prompted the food testing field to urgently develop more advanced mechanized grinding solutions. Utility Model Content

The rotating rod 8 transmits the torque of the motor 7 to the crushing component. The blade 9 achieves food crushing through high-speed rotation and cutting.

[0021] Please see Figures 1-4 The auxiliary components include baffles 10. Two symmetrical baffles 10 are fixedly installed on the upper end of the top cover 19. A connecting rod 11 is provided through the baffles 10. A handle 12 is fixedly installed on the upper end of the connecting rod 11. A spring 13 is fixedly installed between the handle 12 and the baffles 10. A movable plate 14 is fixedly installed on the lower end of the connecting rod 11. The movable plate 14 is semi-circular.

[0023] Working principle: First, invert the device. Rotate the bottom cover 2 to separate the first external thread 4 of the convex ring 3 from the can body 1. At this time, the sealing ring 5 maintains a seal. After placing the food to be tested into the can body 1, rotate the bottom cover 2 in the opposite direction to re-engage the convex ring 3 with the can body 1. The sealing ring 5 ensures the seal at the connection. Then, reset the device to its normal state and fix the overall structure by the second external thread 20 of the top cover 19. Start the motor 7 to drive the rotating rod 8 to rotate, and the blade 9 rotates accordingly to pulverize the food. The operator can observe the pulverization progress through the viewing window 6. During the crushing process, sticky food may adhere to the inner wall of the can 1. At this time, press the handles 12 on both sides at the same time. The connecting rod 11 drives the movable plate 14 to move down under the limiting action of the baffle 10. The reinforcing ring 15 enhances the connection strength. The scraper 17 moves down along the inner wall of the can 1 to scrape off the attached food. The through hole 16 ensures that the rotating rod 8 passes through normally. The locking block 18 fixes the position of the scraper 17. After releasing the handles 12, the spring 13 resets the movable plate 14. Repeat the operation until the food is completely crushed. The device limits the displacement range of the spring 13 by the baffle 10 to ensure the stability of the auxiliary components.
