Abstract
Description
Technical Field
[0001] This utility model relates to the field of flour processing technology, and in particular to a device for producing nutritious flour. Background Technology
[0002] The rising global incidence of chronic diseases is driving market demand for fortified staple foods. According to WHO statistics, about 30% of the global population suffers from micronutrient deficiencies, making functional flour an important solution. Nutritional flour is a type of functional flour made from wheat or other grains that retains or fortifies natural nutrients through special processing techniques. Its core lies in overcoming the nutrient loss caused by traditional processing. In addition to retaining dietary fiber, vitamins, and minerals in the germ and bran, it can also enhance the nutritional density and health value of flour through precise addition or biomodification technologies.
[0003] Traditional flour production equipment cannot simultaneously achieve both the functions of finely grinding grains and preserving their nutritional structure. When traditional roller mills are in operation, friction generates a large amount of heat, causing the grinding temperature to rise. This results in a loss rate of over 40% of heat-sensitive nutrients, such as B vitamins and folic acid. It also denatures proteins and damages the structure of dietary fiber, significantly reducing the nutritional value of the flour and resulting in low product quality. Furthermore, it affects the degree of grain grinding, causing incomplete grinding and the presence of fine particles in the powder.
[0004] Therefore, the traditional nutritional flour production equipment mentioned above cannot simultaneously achieve the two functions of finely grinding grains and preserving their nutritional structure, resulting in a significant reduction in the nutritional value of the flour, low product quality, and the tendency for incomplete grinding and the presence of fine particles in the powder. To address these issues, a nutritional flour production equipment that utilizes cold airflow for heat dissipation and incorporates multi-stage grinding discs can be designed. Utility Model Content
[0005] In order to overcome the fact that traditional flour production equipment cannot simultaneously achieve the two functions of finely grinding grains and preserving their nutritional structure, the nutritional value of flour is greatly reduced, the product quality is low, and it is also easy to cause incomplete grinding and the presence of fine particles in the powder.
[0006] The technical solution of this utility model is as follows: a nutritional flour production device, including a box body; and a feeding pipe, which is rotatably connected inside the box body. A pipe on one side of the feeding pipe is connected to an air supply pipe. A cooling fan is connected to the end of the air supply pipe away from the feeding pipe. Several diffuser pipes are uniformly and fixedly connected inside the feeding pipe. A pipe on one end of the diffuser pipe is connected to an air supply pipe. The end of the diffuser pipe away from the air supply pipe leads to an inner grinding disc. A feeding pipe is fixedly connected above the inner grinding disc. A middle grinding disc is fixedly connected to the outside of the inner grinding disc. An outer grinding disc is fixedly connected to the outside of the middle grinding disc. A grinding shell is rotatably connected to the outside of the outer grinding disc. A feeding pipe is rotatably connected above the grinding shell. A grinding base is fixedly connected to the bottom of the grinding shell.
[0007] Preferably, clean grains are conveyed from the feed pipe to the area below the inner grinding disc, falling above the grinding base. Under the action of centrifugal force, due to the design of the inner, middle, and outer grinding discs from coarse to fine, the grains are first ground by the inner grinding disc, then by the middle grinding disc, and finally ground into flour by the outer grinding disc. At the same time as grinding, a cooling fan generates a cold airflow, which is conveyed through the air duct to the air distribution pipe inside the feed pipe. The air distribution pipe blows the cold airflow between the inner, middle, and outer grinding discs, absorbing the heat generated during grinding and dissipating it, thus protecting the nutrients inside the grains from being destroyed.
[0008] Preferably, several crushing blades are uniformly fixedly connected below the inner grinding disc, and several grinding blocks are uniformly fixedly connected below the inner grinding disc, with the crushing blades and grinding blocks arranged alternately.
[0009] Preferably, grinding heads are uniformly fixedly connected below the middle grinding disc, and grinding strips are uniformly fixedly connected below the outer grinding disc.
[0010] Preferably, a cooling fan is fixedly connected to one side of the upper part of the grinding housing, and a first motor is fixedly connected to the inner side of the upper part of the housing away from the cooling fan.
[0011] Preferably, a driven gear is fixedly connected to the outside of the feed pipe, a driving gear is meshed with one side of the driven gear, a first rotating shaft is fixedly connected in the middle of the driving gear, and a first motor is fixedly connected above the first rotating shaft.
[0012] Preferably, the grinding base is fixedly connected to the housing, a second motor is provided below the grinding base, the second motor is fixedly connected to the housing, and a second rotating shaft is fixedly connected above the output end of the second motor.
[0013] Preferably, the second rotating shaft is rotatably connected to the grinding base, and several scrapers are provided above the grinding base. The scrapers are evenly fixed to the outside of the second rotating shaft, and a discharge pipe is connected to one side of the grinding housing.
[0014] The beneficial effects of this utility model are:
[0015] By using a cooling fan and a diffuser, cold air is delivered into the interior to absorb the heat generated during the grinding process, reducing the temperature of the grains during grinding. This effectively prevents the internal nutritional structure of the grains from being denatured or lost due to heat, ensuring that the produced flour has high nutritional value and good quality. It is also equipped with an inner grinding disc, a middle grinding disc, and an outer grinding disc to achieve multi-stage grinding from coarse to fine, so that the grains can be ground more evenly and comprehensively, resulting in finer flour and preventing the flour from being under-ground.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please see Figures 1-6This utility model provides an embodiment of a nutritional flour production device, including a housing 1 and a feed pipe 2. The feed pipe 2 is rotatably connected inside the housing 1. One side of the feed pipe 2 is connected to an air supply pipe 3. The end of the air supply pipe 3 away from the feed pipe 2 is connected to a cooling fan 4. Several diffuser pipes 201 are uniformly and fixedly connected inside the feed pipe 2. One end of the diffuser pipe 201 is connected to the air supply pipe 3. The end of the diffuser pipe 201 away from the air supply pipe 3 leads to an inner grinding disc 5. The feed pipe 2 is fixedly connected above the inner grinding disc 5. An inner grinding disc 5 is fixedly connected to a middle grinding disc 6 on its outer side. An outer grinding disc 7 is fixedly connected to the outer side of the middle grinding disc 6. A grinding housing 8 is rotatably connected to the outer side of the outer grinding disc 7. A feed pipe 2 is rotatably connected above the grinding housing 8. A grinding base 13 is fixedly connected below the grinding housing 8. Clean grains are conveyed from the feed pipe 2 to below the inner grinding disc 5 and fall above the grinding base 13. Under the action of centrifugal force, due to the design of the inner grinding disc 5, middle grinding disc 6, and outer grinding disc 7 from coarse to fine, the grains are first ground by the inner grinding disc 5 and then by the middle grinding disc 6. Finally, the grains are ground into flour by the outer grinding disc 7. During grinding, the cooling fan 4 generates cold air, which is delivered through the air duct 3 to the air distribution pipe 201 inside the feed pipe 2. The air distribution pipe 201 blows the cold air between the inner grinding disc 5, the middle grinding disc 6, and the outer grinding disc 7, absorbing the heat generated during grinding and dissipating it to protect the nutrients inside the grains from damage. Several crushing blades 501 are evenly fixedly connected below the inner grinding disc 5, and several grinding blocks 502 are also evenly fixedly connected below the inner grinding disc 5. The crushing blades 501 and grinding blocks 502 are arranged alternately. The crushing blades 501 and grinding blocks 502 on the inner grinding disc 5 are used to crush and grind the grains initially, reducing their volume. Grinding heads 601 are evenly fixedly connected below the middle grinding disc 6, and grinding strips 701 are evenly fixedly connected below the outer grinding disc 7. The grinding heads 601 on the middle grinding disc 6 further grind the initially crushed grains into fine particles. Finally, the grinding strips 701 on the outer grinding disc 7 are used to crush the grains into powder, completing the production of nutritious flour.
[0025] Please see Figures 1-6In this embodiment, a cooling fan 4 is fixedly connected to one side of the upper part of the grinding housing 8. A first motor 12 is fixedly connected to the inner side of the upper part of the housing 1, away from the cooling fan 4. The cooling fan 4 generates cold air for cooling, and the first motor 12 outputs torque to achieve rotational grinding. A driven gear 9 is fixedly connected to the outer side of the feed pipe 2. A driving gear 10 is meshed with one side of the driven gear 9. A first rotating shaft 11 is fixedly connected in the middle of the driving gear 10. The first motor 12 is fixedly connected above the first rotating shaft 11. When the first motor 12 outputs torque to the first rotating shaft 11, the first rotating shaft 11 rotates, driving the driving gear 10 to rotate. The driven gear 9 meshes with the driving gear 10 and rotates with the rotation of the driving gear 10, driving the feed pipe 2 to rotate. The grinding base 13 is fixedly connected to the housing 1. A second motor 16 is provided below the grinding base 13. The machine 16 is fixedly connected to the housing 1. A second rotating shaft 14 is fixedly connected above the output end of the second motor 16. The second motor 16 outputs torque to the second rotating shaft 14, driving the second rotating shaft 14 to rotate. The grinding base 13 serves as the main grinding site and is used to hold grains for flour production. The second rotating shaft 14 is rotatably connected to the grinding base 13. Several scrapers 15 are provided above the grinding base 13. The scrapers 15 are evenly fixedly connected to the outside of the second rotating shaft 14. A discharge pipe 17 is connected to one side of the grinding housing 8. The discharge pipe 17 is connected to one side of the housing 1. When the second rotating shaft 14 rotates, it drives the scrapers 15 to rotate above the grinding base 13, scraping off the grains or flour adhering to the grinding base 13, thus grinding the grains or flour. The ground flour is discharged from the housing 1 through the discharge pipe 17.
[0026] During operation, clean grains are conveyed from the feed pipe 2 to the area below the inner grinding disc 5 and fall above the grinding base 13. The first motor 12 outputs torque to the first rotating shaft 11, causing the first rotating shaft 11 to rotate, which in turn drives the drive gear 10 to rotate. The driven gear 9 meshes with the drive gear 10 and rotates along with the drive gear 10, driving the feed pipe 2 to rotate. Under the action of centrifugal force, the grains are first crushed and ground by the crushing blades 501 and grinding blocks 502 on the inner grinding disc 5. Then, the grinding round heads 601 on the middle grinding disc 6 further grind the initially crushed grains into fine particles. Finally, the grinding strips 701 on the outer grinding disc 7 are used to grind the grains. The grains are ground into powder to produce nutritious flour. During the grinding process, the cooling fan 4 generates a cold airflow, which is delivered to the air distribution pipe 201 inside the feed pipe 2 through the air duct 3. The cold airflow is blown between the inner grinding disc 5, the middle grinding disc 6, and the outer grinding disc 7 through the air distribution pipe 201 to absorb the heat generated during grinding and dissipate heat, protecting the nutrients inside the grains from being destroyed. At the same time, the second rotating shaft 14 rotates, driving the scraper 15 to rotate above the grinding base 13 to scrape off the grains or flour adhering to the grinding base 13, thus moving and grinding the grains or flour. The ground flour is discharged from the discharge pipe 17 into the box 1.
[0027] Through the above steps, the cooling fan 4 and the air duct 201 work together to deliver cold airflow into the interior, absorbing the heat generated during the grinding process and reducing the temperature of the grains during grinding. This effectively prevents the internal nutritional structure of the grains from being denatured or lost due to heat, ensuring that the produced flour has high nutritional value and good quality. Furthermore, an inner grinding disc 5, a middle grinding disc 6, and an outer grinding disc 7 are installed to achieve multi-stage grinding from coarse to fine, allowing the grains to be ground more evenly and comprehensively. The resulting flour is finer and avoids incomplete grinding. This solves the problem that traditional nutritional flour production devices cannot simultaneously achieve both fine grinding of grains and preservation of their nutritional structure, resulting in significantly reduced nutritional value, low product quality, and problems such as incomplete grinding and the presence of fine particles in the powder.
