Technical Field
[0001] This utility model relates to the field of flour processing technology, specifically to an anti-caking device for flour processing. Background Technology
[0002] Flour is a powdery substance made from wheat. Based on the amount of protein in flour, it can be divided into high-gluten flour, medium-gluten flour, low-gluten flour, and gluten-free flour. As an indispensable food in people's lives, flour has led to an increasing variety of noodle dishes. However, during flour processing, flour can clump together if left for a long time.
[0003] Patent publication number "CN218475390U" discloses "An anti-caking device for flour processing, including a crushing device.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0025] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0026] Reference Figures 1 to 4 This application provides an anti-caking device for flour processing, including a conveying pipe 1, a crushing component 2 inside the conveying pipe 1, a screening component 3 on the right side of the conveying pipe 1, a bracket 5 fixedly installed at the bottom of the conveying pipe 1, and a feeding port 4 fixedly installed on the outer side of the left end of the conveying pipe 1. The screening component 3 includes a screening box 31, which is fixedly installed on the right side of the conveying pipe 1. A screen 33 and a guide plate 34 are fixedly installed inside the screening box 31. The right side of the screen 33 is lower than the left side, and the guide plate 34 is located below the screen 33. The left side of the guide plate 34 is lower than the right side. A discharge hopper 32 is fixedly installed on the left side of the screening box 31, and the connection between the discharge hopper 32 and the screening box 31 is located at the lowest point on the left side of the guide plate 34.
[0027] A rotating rod 36 is rotatably connected to the top of the screening box 31, and a crushing fan blade 35 is fixedly installed at the bottom of the rotating rod 36, positioned above the screen 33. A second motor 37 is fixedly installed at the top of the screening box 31, and the output end of the second motor 37 movably passes through the top wall of the screening box 31 and is fixedly connected to the rotating rod 36. An auxiliary groove 39 is provided on the right side of the screening box 31, positioned above the screen 33. A connecting block 310 is rotatably connected inside the screening box 31, and a door 38 is fixedly installed at the bottom of the connecting block 310, inserting into the auxiliary groove 39.
[0028] A magnet 311 is fixedly installed on the right side of the box door 38, and a handle 312 is fixedly installed on the right side of the box door 38. The screening box 31 is made of stainless steel, and the lower half of the magnet 311 is attached to the right side of the screening box 31.
[0029] In this embodiment, the screen 33 plays a screening role in the screening box 31. Its inclined design with the right side lower than the left side allows the flour to move to the right under the action of gravity. Smaller flour particles pass through the screen 33 and fall onto the inclined guide plate 34 below. Since the left side of the guide plate 34 is lower than the right side, the flour particles will slide to the left side along the guide plate 34 and finally be discharged through the discharge hopper 32.
[0030] For larger flour lumps that fail to pass through the sieve 33, the second motor 37 drives the rotating rod 36 and the crushing fan blade 35 to rotate. The crushing fan blade 35 crushes these larger lumps again above the sieve 33. The crushed flour is then sieved again. This cycle is repeated to ensure that the flour is fully crushed and sieved, effectively preventing lumpy flour from clogging the sieve 33.
[0031] When it is necessary to clean the screen 33, the operator can pull the handle 312 on the right side of the box door 38. Since the magnet 311 on the right side of the box door 38 is attached to the right side of the screening box 31 made of stainless steel, the magnet can be released when the handle is pulled, so that the box door 38 can be pulled out from the auxiliary groove 39, making it convenient to clean the screen 33 without stopping the machine to disassemble the entire device, which greatly improves production efficiency.
[0032] Reference Figures 1 to 4 In one aspect of this embodiment, the conveying pipe 1 is connected to the screening box 31, and a support frame 24 is fixedly installed at the connection between the conveying pipe 1 and the screening box 31. A first rotating rod 22 is rotatably connected between the support frame 24 and the left inner wall of the conveying pipe 1, and a crushing blade 23 is fixedly installed on the outer side of the first rotating rod 22.
[0033] A first motor 21 is fixedly installed on the left side of the conveying pipe 1. The output end of the first motor 21 movably passes through the side wall of the conveying pipe 1 and is fixedly connected to the first rotating rod 22.
[0034] In this embodiment, flour enters the conveying pipe 1 through the feeding port 4. At this time, the first motor 21 starts and drives the first rotating rod 22 to rotate, thereby causing the crushing blades 23 to initially crush the flour in the conveying pipe 1, breaking down larger lumps of flour, reducing the burden on subsequent processing. The crushed flour enters the screening box 31 through the connection between the conveying pipe 1 and the screening box 31.
[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0036] Working principle: Flour enters the conveying pipe 1 through the feed port 4. At this time, the first motor 21 starts and drives the first rotating rod 22 to rotate, which causes the crushing blades 23 to initially crush the flour in the conveying pipe 1, breaking down larger lumps of flour and reducing the burden on subsequent processing. The crushed flour enters the screening box 31 through the connection between the conveying pipe 1 and the screening box 31. In the screening box 31, the screen 33 plays a screening role. Its inclined design with the right side lower than the left side allows the flour to move to the right under the action of gravity. Smaller flour particles pass through the screen 33 and fall onto the inclined guide plate 34 below. Since the left side of the guide plate 34 is lower than the right side, the flour particles will slide to the left side along the guide plate 34 and finally be discharged through the discharge hopper 32.
[0037] For larger flour lumps that fail to pass through the sieve 33, the second motor 37 drives the rotating rod 36 and the crushing fan blade 35 to rotate. The crushing fan blade 35 crushes these larger lumps again above the sieve 33. The crushed flour is then sieved again. This cycle is repeated to ensure that the flour is fully crushed and sieved, effectively preventing lumpy flour from clogging the sieve 33.
[0038] When it is necessary to clean the screen 33, the operator can pull the handle 312 on the right side of the box door 38. Since the magnet 311 on the right side of the box door 38 is attached to the right side of the screening box 31 made of stainless steel, the magnet can be released when the handle is pulled, so that the box door 38 can be pulled out from the auxiliary groove 39, making it convenient to clean the screen 33 without stopping the machine to disassemble the entire device, which greatly improves production efficiency.
