Description

Technical Field

[0001] This utility model belongs to the field of food grinding technology, specifically relating to a grinding device for testing solid food. Background Technology

[0002] Solid foods have complex and diverse physical forms and chemical compositions. Different types of solid foods possess different characteristics such as hardness, toughness, and fibrous structure, which poses significant challenges to sample preparation. With the continuous advancement of testing technology, the requirements for the uniformity and representativeness of test samples are becoming increasingly stringent. Only by thoroughly grinding solid foods to achieve a suitable particle size can the accuracy and reliability of test results be guaranteed. Some grinding devices employ a single grinding method, such as surface grinding or drum grinding, which cannot be flexibly adjusted according to the different characteristics of solid foods, resulting in unsatisfactory grinding effects. Furthermore, some grinding devices are not adequately designed to address sample flowability and discharge issues. During the grinding process, solid foods easily accumulate and clog inside the device, affecting the continuity and stability of the grinding process. Utility Model Content

[0003] (1) Technical problems to be solved In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a grinding device for testing solid food, which aims to solve the problem that the existing technology only uses flat grinding or drum grinding, which cannot be flexibly adjusted according to the different characteristics of solid food, resulting in unsatisfactory grinding effect.

[0004] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a grinding device for testing solid food, including a grinding box, a crushing box, and a base plate. The crushing box is located above the grinding box and is connected to it. The upper surface of the crushing box is hinged with a top cover, and a rotatable cutting wheel is provided inside. A grinding wheel is rotatably installed inside the grinding box. The upper part of the grinding wheel is a conical structure, and the lower part is a cylindrical structure. The cylindrical structure has a gap with the inner wall of the grinding box.

[0005] Preferably, a rotary motor is fixedly connected to the bottom of the grinding wheel, the rotary motor is fixed inside the bottom of the grinding wheel, and a baffle plate is sleeved on the outside of the rotary motor.

[0006] Preferably, the baffle plate has a discharge port at the bottom of the grinding box.

[0007] Preferably, a drive motor is fixedly installed on the outer wall of the crushing box, and the drive motor is connected to the cutting wheel.

[0008] Preferably, a fixed blade protrudes from the inner wall of the crushing box, and the fixed blade is staggered with the blade on the cutting wheel.

[0009] Preferably, a vertically arranged support rod is fixedly installed at the bottom of the grinding box, and a base plate is fixedly connected to the end of the support rod away from the grinding box.

[0010] Preferably, the upper surface of the base plate is provided with a magnetic chuck, and a receiving box is attached to the magnetic chuck, the receiving box corresponding to the discharge port.

[0011] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This method combines pre-crushing and grinding. First, the solid food is initially crushed into smaller chunks or granules using a staggered arrangement of a cutting wheel and fixed blades, significantly reducing the difficulty and workload of subsequent grinding. Then, the special structure of the grinding wheel—conical at the top and cylindrical at the bottom—finely grinds the pre-crushed solid food, ensuring it is thoroughly ground to achieve the appropriate particle size. This meets the high requirements for sample uniformity and representativeness in solid food testing, thus guaranteeing the accuracy and reliability of the test results.

[0012] The grinding wheel structure and grinding process of this device are designed to adapt to solid foods with varying hardness, toughness, and fibrous structures. The conical grinding wheel guides the solid food smoothly downwards while gradually applying grinding force. For foods with high toughness, it gradually breaks down their fibrous structure during the flow process; for foods with high hardness, it can also pulverize them through continuous compression and grinding. This flexible grinding method effectively improves the grinding effect, ensuring that solid foods with various properties are thoroughly ground. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This specific embodiment is a grinding device for testing solid food, and its structural schematic diagram is shown below. Figure 1 , Figure 2 As shown, the system includes a grinding box 1, a crushing box 6, and a base plate 4. The crushing box 6 is positioned above the grinding box 1 and is connected to it. A top cover 7 is attached to the upper surface of the crushing box 6, and a rotatable cutting wheel 8 is installed inside. A vertically oriented support rod 3 is fixedly installed at the bottom of the grinding box 1, and the end of the support rod 3 furthest from the grinding box 1 is fixedly connected to the base plate 4. A magnetic chuck 9 is provided on the upper surface of the base plate 4, and a receiving box 5 is attached to the magnetic chuck 9, corresponding to the discharge port 12.

[0018] Reference Figure 3 , Figure 4 A grinding wheel 11 is rotatably mounted inside the grinding box 1. The upper part of the grinding wheel 11 is conical, and the lower part is cylindrical, with a gap between the cylindrical structure and the inner wall of the grinding box 1. A rotary motor 10 is fixedly connected to the bottom of the grinding wheel 11, and the rotary motor 10 is fixed inside the bottom end of the grinding wheel 11. A baffle plate 13 is sleeved on the outside of the rotary motor 10. A discharge port 12 is opened on the side of the baffle plate 13 at the bottom of the grinding box 1. A drive motor 2 is fixedly mounted on the outer wall of the crushing box 6, and the drive motor 2 is connected to the cutting wheel 8. A fixed blade 14 protrudes from the inner wall of the crushing box 6, and the fixed blade 14 is staggered with the blades on the cutting wheel 8.

[0019] Working principle: Open the top cover 7 and put the solid food into the crushing chamber 6. Start the drive motor 2, which is fixedly installed on the outer wall of the crushing chamber 6. The drive motor 2 drives the cutting wheel 8 to rotate. Since the inner wall of the crushing chamber 6 is provided with protruding fixed blades 14, and the fixed blades 14 are staggered with the blades on the cutting wheel 8, when the solid food enters the crushing chamber 6, under the action of the rotation of the cutting wheel 8, it cooperates with the fixed blades 14 to perform preliminary cutting and crushing of the solid food, breaking it down into smaller blocks or granules, preparing it for subsequent grinding.

[0020] Pre-crushed solid food enters the grinding chamber 1 through the connection between the crushing chamber 6 and the grinding chamber 1. A grinding wheel 11 is rotatably mounted inside the grinding chamber 1. A rotary motor 10, fixed to the bottom of the grinding wheel 11, is fixedly connected to its inner end. Starting the rotary motor 10 causes the grinding wheel 11 to rotate. The upper part of the grinding wheel 11 is conical, and the lower part is cylindrical, with a gap between the cylindrical structure and the inner wall of the grinding chamber 1. The solid food first contacts the conical part of the grinding wheel 11. Guided by the conical structure, the solid food gradually flows downwards along the outer surface of the grinding wheel 11. As the grinding wheel 11 rotates, the solid food is squeezed between the grinding wheel 11 and the inner wall of the grinding chamber 1, subjected to gradually increasing grinding force, and gradually ground into finer particles.

[0021] During the grinding process, a baffle plate 13 is fitted around the outside of the rotary motor 10. The baffle plate 13 can prevent the ground food particles from entering the interior of the rotary motor 10, ensuring the normal operation of the rotary motor 10. When the solid food is ground to a volume smaller than the gap between the cylindrical structure of the grinding wheel 11 and the inner wall of the grinding box 1, it can continue to flow downwards and be discharged through the discharge port 12 opened at the bottom of the grinding box 1.

[0022] Material receiving stage: A magnetic chuck 9 is provided on the upper surface of the base plate 4, and a material receiving box 5 is attached to the magnetic chuck 9, with the material receiving box 5 corresponding to the discharge port 12. The ground solid food particles fall into the material receiving box 5 through the discharge port 12, completing the entire grinding and collection process.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
