Description

Technical Field

[0001] This utility model relates to the field of dietary fiber processing technology, and in particular to a dietary fiber powder grinding device. Background Technology

[0002] Dietary fiber powder is a product that supplements dietary fiber, containing both soluble and insoluble fiber, offering numerous health benefits. It can help increase satiety, reduce food intake, and thus aid in weight control and weight loss. It also promotes bowel movements, prevents and improves constipation, while providing nutrients to beneficial gut bacteria and improving the intestinal environment. Dietary fiber powder can be made from a variety of fiber-rich ingredients, such as fruits, vegetables, grains, and legumes.

[0003] In existing technologies, raw materials rich in dietary fiber are mostly crushed and dried by extruding them with grinding rollers to make dietary fiber powder. However, after the raw materials are ground by grinding rollers, the particle size of the powder will still be inconsistent, which will affect the yield of fiber powder. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dietary fiber powder grinding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dietary fiber powder grinding device, comprising a machine body, the top of which is provided as a feed inlet, and a grinding roller rotatably connected to the side wall of the machine body. The grinding roller is driven by an external motor. A screen is provided directly below the grinding roller, and spring pieces are fixed at both ends of the screen and are fixedly connected to the side wall of the machine body. The screen is inclined, and a fine grinding roller is provided at the end of the screen away from the grinding roller. The fine grinding roller is driven by an external motor, and an inclined plate is provided directly below the fine grinding roller. The inclined plate is inclined and both ends are fixedly connected to the inner wall of the machine body.

[0006] Preferably, a conveyor support is provided on the side of the machine body, and a conveyor belt mechanism is provided between the top of the conveyor support and the feed inlet. The conveyor belt mechanism consists of a conveyor roller and a conveyor belt, and the conveyor roller is driven by a conveyor drive motor. Transport boxes are fixedly arranged on the surface of the conveyor belt. Currently, dietary fiber raw materials are mainly fed into the feed inlet manually, which not only increases labor but also poses a certain danger due to the high height of the grinding device. To address this problem, this utility model adopts an automatic feeding mechanism. The raw materials are placed in the transport box, and the conveyor drive motor is turned on to drive the conveyor roller to rotate, thereby driving the conveyor belt to rotate and moving the transport box towards the feed inlet. When the transport box moves above the feed inlet, the raw materials fall into the feed inlet due to gravity, achieving the purpose of automatic feeding and reducing labor and danger.

[0007] Preferably, the bottom of the screen is provided with a cam, both ends of which are rotatably connected to the inner wall of the machine body. The cam is driven by an external motor. When a large amount of fiber powder with a large diameter falls onto the surface of the screen, it is easy to block the screen mesh. It is difficult for the fiber powder with a large diameter to fall into the fine grinding roller by its own gravity. To address this problem, this utility model adopts a cam structure, which drives the cam to rotate through an external motor, thereby causing the screen to vibrate, preventing the fiber powder with a large diameter from blocking the screen mesh, and improving the grinding efficiency.

[0008] Preferably, the bottom of the screen is provided with a protrusion, and the protrusion is corrugated. The corrugated protrusion cooperates with the cam to continuously generate vibration, which further increases the vibration amplitude and thus further increases the falling speed of fiber powder with a larger powder diameter.

[0009] Preferably, the inclination angles of the screen and the inclined plate are both set between 30 and 45 degrees. A smaller angle will make it difficult for fiber powder with a larger diameter to fall, while a larger angle will increase the overall height of the grinding device, thereby increasing the cost. Tests have shown that setting the inclination angles of the screen and the inclined plate between 30 and 45 degrees is optimal.

[0010] Preferably, the inclined plate is equipped with a heating wire inside to improve the drying efficiency of the fiber powder and facilitate packaging and sealing.

[0011] Preferably, the end of the feed inlet near the conveyor belt mechanism is set as an inclined surface, so that when the raw material falls on the inclined surface, it will still fall into the feed inlet.

[0012] Beneficial effects

[0013] 1. In existing technologies, raw materials rich in dietary fiber are mostly crushed and dried by extrusion rollers to produce dietary fiber powder. However, after the raw materials are ground by the grinding rollers, the particle size of the powder is still inconsistent, which affects the yield of fiber powder. To address this problem, this utility model adopts a multi-grinding device. When the dietary fiber raw materials enter the grinding rollers through the feed inlet, the external motor is turned on to drive the grinding rollers to grind the raw materials. After grinding, the raw materials pass through a screen. The fiber powder with a smaller diameter falls through the screen into the inclined plate, while the fiber powder with a larger diameter enters the fine grinding roller. Another set of external motors is turned on to drive the fine grinding roller to rotate for secondary extrusion and grinding. Finally, the powder falls into the inclined plate, and the workers can collect it from the discharge port on the side of the machine. This makes the particle size of the dietary fiber powder almost uniform, thus improving the yield of fiber powder.

[0014] 2. Existing dietary fiber raw materials are mainly fed into the inlet manually, which not only increases labor but also poses a certain danger due to the height of the grinding device. To address this issue, this utility model adopts an automatic feeding mechanism. The raw materials are placed in the transport box, and the conveyor drive motor is turned on to drive the conveyor roller to rotate, thereby driving the conveyor belt to rotate and moving the transport box towards the inlet. When the transport box moves above the inlet, the raw materials fall into the inlet due to gravity, achieving the purpose of automatic feeding and reducing labor and danger.

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0024] Reference Figure 1-4A dietary fiber powder grinding device includes a body 1, with a feed inlet at the top and a grinding roller 3 rotatably connected to the side wall of the body 1. The grinding roller 3 is driven by an external motor. A screen 4 is located directly below the grinding roller 3, with spring pieces 8 fixed at both ends of the screen 4 and fixedly connected to the side wall of the body 1. The screen 4 is inclined, and a fine grinding roller 5 is located at the end of the screen 4 away from the grinding roller 3. The fine grinding roller 5 is driven by an external motor, and an inclined plate 6 is located directly below the fine grinding roller 5. The inclined plate 6 is also inclined, with the inclination angle between the screen 4 and the inclined plate 6 set between 30 and 45 degrees. A smaller angle would make it difficult for larger diameter fiber powder to fall, while a larger angle would increase the overall height of the grinding device, thus increasing costs. Tests have shown that setting the inclination angle between the screen 4 and the inclined plate 6 between 30 and 45 degrees is optimal. Both ends of the inclined plate 6 are fixedly connected to the inner wall of the body 1, and a heating wire is installed inside the inclined plate 6 to improve the drying efficiency of the fiber powder and facilitate packaging and sealing.

[0025] A conveyor support 2 is provided on the side of the machine body 1. A conveyor belt mechanism 7 is provided between the top of the conveyor support 2 and the feed inlet. The conveyor belt mechanism 7 consists of a conveyor roller and a conveyor belt. The conveyor roller is driven by a conveyor drive motor 11. A transport box 12 is fixed on the surface of the conveyor belt. The existing dietary fiber raw materials are mainly fed into the feed inlet manually, which not only increases labor but also poses a certain danger due to the high height of the grinding device. To address this problem, this utility model adopts an automatic feeding mechanism. The raw materials are placed in the transport box 12, and the conveyor drive motor 11 is turned on to drive the conveyor roller to rotate, thereby driving the conveyor belt to rotate and moving the transport box 12 towards the feed inlet. When the transport box 12 moves above the feed inlet, the raw materials fall into the feed inlet due to gravity, achieving the purpose of automatic feeding and reducing labor and danger. The end of the feed inlet near the conveyor belt mechanism 7 is set as an inclined surface 101. When the raw materials fall on the inclined surface 101, they will still fall into the feed inlet.

[0026] The bottom of the screen 4 is equipped with a cam 9, both ends of which are rotatably connected to the inner wall of the machine body 1. The cam 9 is driven by an external motor. When a large amount of fiber powder with a large diameter falls onto the surface of the screen 4, it easily blocks the mesh of the screen 4 and is difficult to fall into the fine grinding roller 5 by its own gravity. To address this problem, this invention adopts a cam 9 structure, which drives the cam 9 to rotate through an external motor, thereby causing the screen 4 to vibrate and preventing the fiber powder with a large diameter from blocking the mesh of the screen 4, thus improving the grinding efficiency. The bottom of the screen 4 is equipped with a protrusion 10, which is corrugated. The corrugated protrusion 10 cooperates with the cam 9 to continuously generate vibration, further increasing the vibration amplitude and thus further increasing the falling speed of the fiber powder with a large diameter.

[0027] The working principle of this utility model is as follows: The raw material is placed in the transport box 12, and the conveyor drive motor is turned on to drive the conveyor roller to rotate, thereby driving the conveyor belt to rotate and moving the transport box 12 towards the feed inlet. When the transport box 12 moves above the feed inlet, the raw material falls into the feed inlet due to gravity. When the dietary fiber raw material enters the grinding roller 3 through the feed inlet, the external motor is turned on to drive the grinding roller 3 to grind the raw material. After grinding, the raw material passes through the screen. First, the external motor is turned on to drive the cam to rotate, thereby driving the screen to vibrate. Fiber powder with smaller diameter falls through the screen into the inclined plate, while fiber powder with larger diameter enters the fine grinding roller 5. Another set of external motors is turned on to drive the fine grinding roller to rotate for secondary extrusion and grinding. Finally, it falls into the inclined plate, and the staff collects it from the discharge port on the side of the machine.
