Description

Technical Field

[0002] Soy milk is a favorite drink of the Chinese people and a nutritious food suitable for all ages. It enjoys the reputation of "plant milk" in Europe and the United States. Soy milk is rich in plant protein and phospholipids, as well as vitamins B1, B2 and niacin. In addition, soy milk also contains minerals such as iron and calcium, especially the calcium it contains, which is very suitable for all kinds of people, including the elderly, adults, teenagers, children, etc.

[0003] Among them, the ingredients for five-grain soy milk include traditional soybeans, as well as corn, millet, black rice, buckwheat, oats, red beans, sorghum, mung beans and other grains. In the production process of five-grain soy milk, the grains need to be screened to remove impurities and unqualified raw materials to ensure the quality of the raw materials. The screened raw materials are crushed into powder by grinding equipment to refine the raw materials, and then the powdered raw materials are mixed by mixing equipment, and finally the five-grain soy milk powder is produced after quantitative packaging.

[0004] In the prior art, raw materials are usually mixed in a one-time feeding mixing method. This feeding method easily leads to stratification and aggregation of various powder raw materials, which makes it difficult to mix subsequent raw materials and achieve uniform mixing, resulting in nutritional imbalance of the produced grain soy milk.

[0031] like Figure 1 to Figure 3 As shown, a mill mixing device for processing whole grains comprises a mixing box 1, a discharging pipe with a discharging valve is arranged at the lower end of the mixing box 1, at least two crushing boxes 2 are arranged at the upper end of the mixing box 1, and an end cover is hinged at the upper end of the crushing box 2, and the lower end of the crushing box 2 is a funnel-shaped structure, and a guide pipe 3 communicating with the inside of the mixing box 1 is arranged at the lower end of the funnel-shaped structure, and a plurality of support rods 4 are arranged on the wall of the guide pipe 3, and a guide cylinder 5 coaxial with the guide pipe 3 is arranged between the plurality of support rods 4, and a vertical rod 6 is slidably connected to the inner surface of the guide cylinder 5, and the vertical rod 6 penetrates the guide cylinder 5, and a lower plate 7 is arranged at the upper end of the vertical rod 6, and a tension spring 8 is arranged between the lower plate 7 and the guide cylinder 5;

[0032] The mixing box 1 is internally rotatably connected with a mixing shaft 9, and the mixing shaft 9 is provided with an inclined disc 10 located at the upper part of the mixing box 1. The lower end of the vertical rod 6 is in close contact with the upper surface of the inclined disc 10 under the tension of the tension spring 8.

[0033] It also includes a crushing mechanism disposed inside each crushing box 2 for crushing the corresponding raw material and a mixing mechanism disposed on the mixing shaft 9 for mixing various raw material powders;

[0034] It also includes a driving mechanism for driving the crushing mechanism and the mixing shaft 9 to work.

[0035] During specific use, various cereals and grains raw materials are respectively put into the corresponding grinding box 2 and then the end cover is closed. The driving mechanism drives the various grinding mechanisms and the mixing shaft 9 to work. The mixing shaft 9 drives the inclined disk 10 to rotate and the mixing mechanism to work. The grinding mechanisms in each grinding box 2 grind various cereals and grains raw materials. The inclined disk 10 intermittently lifts up the corresponding discharge plate 7 through each vertical rod 6. The various raw material powders after grinding fall into the mixing box 1 through the gap between the discharge plate 7 and the funnel-shaped structure at the lower end of the grinding box 2, so as to realize the continuous discharge of various raw material powders in sequence. The mixing mechanism mixes the various raw material powders falling into the mixing box 1, and the evenly mixed cereal soy milk powder is discharged from the discharge pipe.

[0036] like Figure 3 As shown, in order to achieve the purpose of adjusting the specific gravity of various raw materials, preferably, the vertical rod 6 is a retractable device, and the vertical rod 6 can be an electric push rod or a cylinder. By adjusting the telescopic amount of the retractable device, the size of the gap between the discharge plate 7 and the funnel-shaped structure at the lower end of the crushing box 2 can be adjusted, thereby adjusting the discharge specific gravity between various raw material powders.

[0037] like Figure 3 As shown, in order to achieve the purpose of improving the mixing effect of the raw material powder, preferably, a breaking cone 11 is provided at the upper end of the discharge tray 7. During the lifting process of the discharge tray 7, the breaking cone 11 will be driven to lift and lower in the crushing box 2 at the same time, so as to avoid the powder raw material from gathering on the upper surface of the discharge tray 7, thereby improving the discharge efficiency and making the discharge more complete. At the same time, the breaking cone 11 has a guiding effect on the powder raw material, so that the powder raw material can fall from the gap between the discharge tray 7 and the funnel-shaped structure at the lower end of the crushing box 2. In addition, it also plays a role in clearing the guide pipe 3, effectively avoiding blockage of the guide pipe 3.

[0041] When in use, various cereals and grains are put into the corresponding crushing box 2 respectively, and then the end cover is closed. The motor 27 drives the driving gear 28 to rotate, and the driving gear 28 drives the mixing shaft 9 to rotate through the second driven gear 29. The mixing shaft 9 drives the cylinder 16, the mounting plate 20 and the driving bevel gear 30 to rotate. The driving bevel gear 30 drives the crushing rollers 12 in each crushing box 2 to rotate through each driven bevel gear 19. The moving knife 13 on the crushing roller 12 and the fixed knife 14 on the inner wall of the crushing box 2 crush the raw materials into powder. The powder raw materials that meet the particle size pass through the arc screen 15 and fall into the lower part of the crushing box 2. At the same time, the rotating moving knife 13 can break up the soft lumps in the material, and has a good crushing and screening effect for powders with high humidity. The cylinder 16 drives the inclined disc 10 to intermittently lift the corresponding unloading disc 7 upward through each vertical rod 6. The various raw material powders after crushing fall into the mixing box 1 through the gap between the discharge plate 7 and the funnel-shaped structure at the lower end of the crushing box 2, so as to realize the continuous discharge of various raw material powders in sequence. The mounting plate 20 drives the stirring blades 25 on each stirring shaft 24 to revolve around the mixing shaft 9. The sun gear 18 drives the first driven gear 22 to rotate through each planetary gear 21. The first driven gear 22 drives the stirring blades 25 on the stirring shaft 24 to rotate through the eccentric rod 23, so as to mix the various raw material powders falling into the mixing box 1. The rotation direction of the eccentric rod 23 is opposite to that of the mounting plate 20, so as to improve the mixing effect of the raw materials. In addition, the screw conveyor 26 lifts the raw materials at the bottom of the mixing box 1 upward for multiple mixing, so as to further improve the mixing effect of the raw materials. The evenly mixed five-grain soy milk powder is discharged from the discharge pipe.

The fluid cavity 33 can be passed with a heating medium such as hot water and hot oil. During the mixing process of the whole grain powder, the heating medium continuously exchanges heat with the whole grain powder through the side wall of the mixing box 1, so that the whole grain powder is dried during the mixing process, and the moisture generated during the drying process is discharged from the dehumidification port 34, thereby improving the quality of the finished product of the whole grain soy milk powder.
