[0001] This utility model relates to the field of leafing agent processing technology, and in particular to a grinding structure for processing leafing agents. Background Technology

[0002] Leavening agents are chemical reagents used in industries such as manufacturing and food processing. They release gases (CO2, NH3, etc.) to form a honeycomb structure, increasing the volume of products by 2-4 times. They are widely used in daily life. However, the processing of leavening agents requires grinding the prepared agents. Existing grinding rollers are prone to problems during grinding, such as the leavening agent powder overheating and sticking to the roller surface due to compression. This prevents further grinding, necessitating machine shutdown and cleaning, resulting in low work efficiency. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a grinding structure for processing leavening agents, which performs low-temperature grinding and cleans the surface of the ceramic grinding roller to avoid material sticking, which would adversely affect subsequent grinding and require machine shutdown for maintenance.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0020] like Figures 1-3 As shown, this embodiment provides a grinding structure for processing leavening agents, including a mounting frame 1 installed at the bottom of the grinding chamber, and a pair of ceramic grinding rollers 3 are mounted on the mounting frame 1 via a bearing seat 2. Each ceramic grinding roller 3 has micro-tooth patterns 4 engraved on its surface, and the gap between the micro-tooth patterns 4 is 0.1-1mm. This constitutes the grinding body, which can grind leavening agent powder of the required specifications.

[0021] The mounting frame 1 is equipped with two drive motors 5. The shaft end of the ceramic grinding roller 3 is fitted with a first pulley 6. The output shaft of the drive motor 5 is equipped with a second pulley 7. A transmission belt 8 is installed between the first pulley 6 and the second pulley 7. One drive motor 5 drives one ceramic grinding roller 3 to rotate. The pair of ceramic grinding rollers 3 are independently controlled, which has a better grinding effect.

[0022] The ceramic grinding roller 3 is equipped with a cooling mechanism; this cools the ceramic grinding process and prevents it from becoming too hot, which could lead to accelerated decomposition of the leavening agent, damage to active ingredients, and alteration of the physical structure, thus causing failure.

[0023] It also includes a cleaning mechanism 9 located below the ceramic grinding roller 3 and used to clean the lower roller surface of the ceramic grinding roller 3. The cleaning mechanism 9 includes a cleaning brush roller 10 located below the ceramic grinding roller 3 and in contact with the lower roller surface of the ceramic grinding roller 3. This cleans the surface of the ceramic grinding roller to prevent material from sticking and causing adverse effects on subsequent grinding, which would require machine shutdown for maintenance.

[0024] The cooling mechanism includes a cooling channel 12 that runs through both ends of the ceramic grinding roller 3. The connecting shafts at both ends of the ceramic grinding roller 3 are provided with rotary joints 13 that are connected to the cooling channel 12. The rotary joints 13 are connected to an external water chiller 14 via a circulation pipe.

[0025] The cleaning brush roller 10 is connected to the ceramic grinding roller 3 via a transmission mechanism. This transmission mechanism includes rollers 15 located at both ends of the cleaning brush roller 10 and in contact with the surface of the ceramic grinding roller 3. Mounting seats 16 are rotatably mounted at both ends of the cleaning brush roller 10 via bearings. A clamping spring rod 18 is provided between the mounting seat 16 and the machine body 17 to clamp the cleaning brush roller 10. Under the action of the clamping spring rod, the rollers 15 at both ends of the cleaning brush roller 10 are in contact with the surface of the ceramic grinding roller 3. When the ceramic grinding roller 3 rotates, it drives the rollers to rotate, which in turn drives the cleaning brush roller 10 to rotate, thereby cleaning the surface of the cleaning brush roller 10 and preventing material adhesion. The rollers 15 are fixedly connected to the two ends of the cleaning brush roller 10. The bristles on the cleaning brush roller 10 are longer than the radius of the rollers 15, ensuring good contact between the bristles on the cleaning brush roller 10 and the surface of the ceramic grinding roller 3.

[0026] The roller 15 has a rubber layer 19 on its surface, which serves to prevent collision and wear. The diameter of the roller is smaller than that of the ceramic grinding roller 3, so that a speed difference is formed between the cleaning brush roller 10 and the ceramic grinding roller 3, thereby enabling the cleaning brush roller 10 to have a better cleaning effect on the ceramic grinding roller 3.

[0027] The two ceramic grinding rollers 3 move toward each other, and the ceramic grinding rollers 3 squeeze and shear the blocky loosening agent between the two ceramic grinding rollers 3, which has a better grinding effect.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Working principle: The grinding body consists of a pair of ceramic grinding rollers 3. The two ceramic grinding rollers 3 move towards each other, squeezing and shearing the blocky leavening agent between them. This process is independently controlled, resulting in a better grinding effect. Furthermore, the ceramic grinding rollers 3 are equipped with a cooling mechanism to cool the ceramic grinding process, preventing excessive temperature from accelerating the decomposition of the leavening agent, damaging active ingredients, or altering its physical structure, which could lead to failure. In addition, this invention includes a cleaning mechanism 9 below the ceramic grinding rollers 3 to clean the lower roller surface, preventing material adhesion and avoiding adverse effects on subsequent grinding, which could necessitate machine shutdown for maintenance.

[0030] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
