Description

Technical Field

[0001] This utility model relates to the field of grain vinegar production technology, and in particular to a grain vinegar raw material pretreatment device. Background Technology

[0002] The raw materials for brewing mixed grain vinegar are diverse, and in order to ensure the fermentation effect, the raw materials need to be pre-treated.

[0003] A search revealed a prior art health-promoting vinegar (publication number: CN1203168C). This vinegar comprises the following components in the indicated amounts (by weight): 90-94% bran and coarse grains, 6-10% edible medicinal plants, and trace amounts of saccharifying enzymes and acetic acid bacteria. The raw materials for brewing the vinegar are crushed, mixed, and steam-heated to 25-35°C. Then, the crushed natural edible medicinal plants, saccharifying enzymes, and acetic acid bacteria are added, followed by stirring and fermentation. The acetic acid produced during natural fermentation is used to absorb the nutrients from the bran and coarse grains and the effective medicinal components from the natural edible medicinal plants. The vinegar is then extracted through leaching.

[0004] Existing technologies propose a process for brewing vinegar using coarse grains as raw materials. However, coarse grains require a series of treatments before fermentation. Publication number CN107597355A discloses an existing technology called a grain pulverizer, which uses a motor to drive pulverizing blades to grind the grains. For vinegar-making raw materials, the degree of coarseness of the pulverization varies, which will affect the degree of fermentation in the later stages. Therefore, there is room for optimization in the pretreatment of coarse grain raw materials in existing technologies.

[0005] Therefore, we propose a pretreatment device for raw materials for mixed grain vinegar. Utility Model Content

[0006] The present invention mainly addresses the technical problem of inconsistent particle uniformity in the pre-treatment of raw materials, and provides a pre-treatment device for mixed grain vinegar raw materials.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a pretreatment device for mixed grain vinegar raw materials, comprising:

[0008] A screening box, a grinding box is fixedly installed on the top of the screening box, a feeding box is fixedly installed on the top of the grinding box, two mutually driven crushing rollers are rotatably arranged inside the feeding box, and a vibrating screen is provided inside the cavity of the screening box.

[0009] The grinding structure is set inside the grinding chamber for crushing raw materials. The grinding structure includes a shell, a main shaft, a push plate, and a grinding body.

A motor-driven main shaft is fixedly installed at the bottom of the shell. The push plate and the grinding body can crush the material after it has been crushed by the crushing roller.

[0010] In a preferred embodiment of this utility model, the outer shell includes a grinding section, a falling section, and a guiding section. The grinding section and the guiding section are both fixedly connected to the falling section, and the grinding section, the falling section, and the guiding section together form an hourglass-shaped outer shell.

[0011] In a preferred embodiment of this utility model, the falling section is a circular tube, and both the grinding section and the guiding section are funnel structures. The smaller ends of the grinding section and the guiding section are fixedly connected to the two ends of the falling section, respectively. The guiding section is located above the grinding section, and the motor is fixedly installed on the lower end face of the grinding section.

[0012] In a preferred embodiment of this utility model, the push plate is formed into a spiral plate, and the main shaft and the push plate extend from the falling section to the guide section cavity.

[0013] In a preferred embodiment of this invention, the grinding body is a frustum and is located inside the cavity of the grinding section.

[0014] As a preferred embodiment of this utility model, the grinding structure further includes raised ribs, and several raised ribs are fixedly arranged on the circumferential surface of the grinding body, forming a concave-convex kneading surface through the multiple raised ribs.

[0016] Beneficial effects

[0017] This utility model provides a pretreatment device for raw materials for mixed grain vinegar. It has the following beneficial effects:

[0018] 1. This pretreatment device for raw materials of mixed grain vinegar is driven by a motor to rotate the main shaft. The main shaft drives the push plate and the grinding body to rotate synchronously and in the same direction. The push plate can convey the particles crushed by the two crushing rollers downward. The size of the grinding body is smaller than the size of the outer shell. The particles conveyed by the push plate are squeezed and ground through the gap between the grinding body and the inner wall of the outer shell, so that the mixed grain particles can be further crushed and the particle size can meet the fermentation requirements. Through the rotating push plate and grinding body, the funnel-shaped guide section can better collect the raw materials crushed by the crushing rollers and feed them to the falling section in conjunction with the rotating push plate. The umbrella-shaped grinding body, together with the inverted funnel-shaped grinding section, allows the particles to be gradually squeezed and ground during the downward movement, improving the grinding effect, inhibiting material blockage, and ensuring the uniformity of powder coarseness after a series of treatments, thus ensuring the fermentation effect in the later stage.

[0019] 2. This pretreatment device for raw materials of mixed grain vinegar, by setting multiple ribs, specifically, the ribs are semi-cylindrical and integrally formed with the grinding body. The multiple ribs make the circumferential surface of the grinding body form an uneven kneading surface, which can ensure the extrusion and grinding effect of the grinding body on the circumference of the grinding body on the particles. The spirally distributed ribs can also promote the flow of materials in the gap between the grinding body and the inner wall of the grinding section, which facilitates the flow of powder into the screening box cavity for screening by the vibrating screen.

[0026] A pretreatment device for raw materials for mixed grain vinegar, such as Figure 1 and Figure 2 As shown, it includes:

[0027] A screening box 10 is provided, and a grinding box 11 is fixedly installed on the top of the screening box 10. A feeding box 12 is fixedly installed on the top of the grinding box 11. Two mutually driving crushing rollers 14 are rotatably arranged inside the feeding box 12. A vibrating screen 13 is provided inside the cavity of the screening box 10. Specifically, the ends of the two crushing rollers 14 are fixedly installed with meshing gears. A geared motor is fixedly installed outside the feeding box 12. The output end of the geared motor is fixedly connected to one of the crushing rollers 14. The two counter-rotating crushing rollers 14 crush the grains, such as rice. At the same time, the two counter-rotating crushing rollers 14 can also feed the grains into the grinding box 11. The grain raw materials are pre-treated by the crushing rollers 14. With the fine screening of the vibrating screen 13, large particles of impurities are removed. The raw materials of suitable size are used to brew grain vinegar.

[0028] The chambers of the screening box 10, grinding box 11 and feeding box 12 are all interconnected. The bottom of the screening box 10 is provided with a window for discharging. The powder after fine screening is discharged from the window, and larger particles are shaken from the top of the vibrating screen 13 into the collection box on one side of the screening box 10.

[0029] like Figure 4 and Figure 5 As shown, the grinding structure is set in the grinding chamber 11 for crushing raw materials. The grinding structure includes a shell, a main shaft 30, a push plate 31, and a grinding body 32. The shell is fixedly set in the grinding chamber 11. The push plate 31 is fixedly connected to the main shaft 30. The grinding body 32 is fixedly connected to the main shaft 30. The bottom of the shell is fixedly equipped with a motor-driven main shaft 30. The push plate 31 and the grinding body 32 can crush the material crushed by the crushing roller 14. The push plate 31 forms a spiral plate. The main shaft 30 and the push plate 31 extend from the falling section 21 to the guide section 22 chamber. The grinding body 32 is a frustum and is located in the grinding section 20 chamber.

[0030] The main shaft 30 is driven by a motor to rotate. The main shaft 30 drives the push plate 31 and the grinding body 32 to rotate synchronously and in the same direction. The push plate 31 can convey the particles crushed by the two crushing rollers 14 downwards. The size of the grinding body 32 is smaller than the size of the outer shell. The particles conveyed by the push plate 31 are squeezed and ground through the gap between the grinding body 32 and the inner wall of the outer shell, so that the grain particles can be further crushed and the particle size can meet the fermentation requirements.

[0031] like Figure 3 As shown, the outer shell includes a grinding section 20, a falling section 21, and a guiding section 22. Both the grinding section 20 and the guiding section 22 are fixedly connected to the falling section 21. The grinding section 20, the falling section 21, and the guiding section 22 together form an hourglass-shaped outer shell. The falling section 21 is a circular tube, and both the grinding section 20 and the guiding section 22 are funnel structures. The smaller ends of the grinding section 20 and the guiding section 22 are fixedly connected to the two ends of the falling section 21, respectively. The guiding section 22 is located above the grinding section 20, and the motor is fixedly installed on the lower end face of the grinding section 20.

[0032] The funnel-shaped guide section 22 can better collect the raw materials crushed by the crushing roller 14 through the rotating push plate 31 and the grinding body 32. The rotating push plate 31 feeds the material towards the falling section 21. The umbrella-shaped grinding body 32, together with the inverted funnel-shaped grinding section 20, allows the particles to be gradually squeezed and ground during the downward movement, improving the grinding effect and suppressing material blockage.

[0033] like Figure 5As shown, the grinding structure also includes raised ribs 33. Several raised ribs 33 are fixedly arranged on the circumferential surface of the grinding body 32. The grinding body 32 forms an uneven kneading surface through multiple raised ribs 33. As a supplement to the above solution, by setting multiple raised ribs 33, specifically, the raised ribs 33 are semi-cylinders. The raised ribs 33 are integrally formed with the grinding body 32. The multiple raised ribs 33 make the circumferential surface of the grinding body 32 form an uneven kneading surface, which can ensure the extrusion and grinding effect of the grinding body 32 on the circumference of the particles. The spirally distributed raised ribs 33 can also promote the flow of materials in the gap between the grinding body 32 and the inner wall of the grinding section 20, which facilitates the flow of powder into the screening box 10 cavity and screening by the vibrating screen 13.

[0034] The working principle of this utility model is as follows: Two counter-rotating crushing rollers 14 crush grains, such as rice. At the same time, the two counter-rotating crushing rollers 14 can also feed the material into the grinding box 11. The main shaft 30 is driven by a motor to rotate. The main shaft 30 drives the push plate 31 and the grinding body 32 to rotate synchronously and in the same direction. The push plate 31 can convey the particles crushed by the two crushing rollers 14 downwards. The rotating push plate 31 and the grinding body 32, the funnel-shaped guide section 22 can better collect the raw materials crushed by the crushing rollers 14. With the rotation of the push plate 31, the material is fed into the falling section 21. The umbrella-shaped grinding body 32, together with the inverted funnel-shaped grinding section 20, allows the particles to be gradually squeezed and ground during the downward movement, improving the grinding effect. The ground powder is sent to the vibrating screen 13. After fine screening, the powder is discharged from the window. Larger particles are shaken from the top of the vibrating screen 13 into the collection box on one side of the screening box 10, realizing the pretreatment of the raw materials for vinegar brewing.
