Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to a pulping device. Background Art

[0002] In the production process of soy products, the grinding device usually needs to grind multiple times to meet the requirements. This is because the protein and other nutrients in soybeans need to be released under certain physical and chemical conditions, and these conditions usually need to be achieved through multiple grinding.

[0003] The prior art usually stops the machine after the initial grinding, then adjusts the distance between the two grinding stones to a smaller value, and then sends the soy milk to the grinding device through a circulation device for fine grinding. In order to effectively improve the nutritional value and taste of the soy milk, this process often needs to be repeated several times. This method is not only time-consuming, but also complicated to operate, affecting the production efficiency of soy milk; at the same time, due to the large difference in precision when adjusting the distance between the two grinding stones, the quality of the ground soy milk is unstable, affecting the taste and nutritional value of the soy products. Utility Model Content

[0004] The utility model aims to provide a grinding device to solve the problem that continuous grinding cannot be achieved and the quality of ground soymilk is unstable as mentioned in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A pulping device for grinding soybeans includes a pulp collecting box, a static grinding stone and a dynamic grinding stone.

[0007] Grinding stone, etc.; a bracket is connected to the inner wall on the upper side of the slurry collecting box; the static grinding stone is suspended below the bracket, the bottom surface of the static grinding stone is an inner concave surface, the top surface of the inner concave surface is a plane, the upper ends of its two side surfaces are curved surfaces, and the lower ends are inclined surfaces; the dynamic grinding stone is rotatably arranged on the inner wall on the lower side of the slurry collecting box, the upper end of the dynamic grinding stone is inserted into the inner concave surface of the static grinding stone, the top surface of the dynamic grinding stone is a plane, and its two sides are inclined surfaces, and the inclination of the inclined surface is greater than the inclination of the inclined surfaces on both sides of the static grinding stone, and the plane of the dynamic grinding stone transitions to its inclined surface through an arc surface; wherein, the plane of the bottom surface of the dynamic grinding stone and the plane of the top surface of the static grinding stone constitute a coarse grinding chamber for coarse grinding of soy milk; the inclined surface of the dynamic grinding stone and the curved surface of the static grinding stone constitute a buffer chamber for caching soy milk; the inclined surface of the dynamic grinding stone and the inclined surface of the static grinding stone constitute a fine grinding chamber for fine grinding of soy milk.

[0008] Furthermore, the slurry collecting box is used to collect the soy milk generated after the soybeans are ground.

[0009] Furthermore, the bracket is used to support the static grinding stone so that it is kept on the inner wall of the upper side of the slurry collecting box, which is convenient for the coordination and grinding of the static grinding stone and the dynamic grinding stone.

[0010] Furthermore, the coarse grinding chamber is used to perform preliminary grinding on the soybeans to release the protein and other nutrients in the soybeans.

[0011] Furthermore, the plane of the movable grinding stone transitions to its inclined surface through an arc surface, and the arc surface is used to guide the soy milk. The design of the arc surface can make the soy milk flow more smoothly, effectively improve the fluidity of the soy milk, and facilitate the soy milk to flow from the coarse grinding chamber into the buffer chamber.

[0012] Furthermore, the buffer chamber is used to balance the flow between the coarse grinding chamber and the fine grinding chamber.

[0013] Furthermore, the fine grinding chamber is used for fine grinding soy milk, and further processing the soy milk to meet higher precision requirements, improve the quality of the soy milk, and thus improve the taste and nutritional value of soy products.

[0014] Furthermore, the roughness of the bottom surface of the static grinding stone and the surface of the dynamic grinding stone is between 0.2-0.6 μm; when the soy milk contacts the grinding stone during the grinding process, the surface with greater roughness can increase the friction between the grinding stone and the soy milk, making the soy milk easier to grind, thereby improving the grinding efficiency and quality; at the same time, when the soy milk contacts the grinding stone during the grinding process, the surface with greater roughness can increase the friction between the grinding stone and the soy milk, thereby reducing the adhesion of the soy milk and avoiding the gelatinization of the soy milk during the grinding process.

[0015] Furthermore, the height of the coarse grinding chamber is between 10-20 mm. This design allows the soybeans to be ground in the coarse grinding chamber for a longer time, the grinding effect is more uniform, and the protein and starch in the soybeans can be better separated. In addition, the height of the coarse grinding chamber matches the height of the soybeans, which can keep the soybeans in a stable state during the grinding process and reduce the movement and swing of the soybeans during the grinding process, thereby improving the efficiency and accuracy of the grinding; the width of the fine grinding chamber decreases from top to bottom. The maximum width of the fine grinding chamber is between 5-7 mm and the minimum width is between 2-3 mm. This design can gradually reduce the flow rate of the soy milk in the fine grinding chamber, so that the soy milk is ground more evenly, reduce the friction and collision of the soy milk during the grinding process, thereby reducing the energy loss of the soy milk during the grinding process and improving the grinding efficiency. In addition, the width of the fine grinding chamber gradually decreases, which can gradually increase the pressure on the soy milk during the grinding process, so that the soy milk is continuously finely ground multiple times during the flow in the fine grinding chamber, thereby more thoroughly separating the protein and starch in the soybeans and improving the quality and taste of the soy milk.

[0016] Furthermore, the volume of the buffer chamber is at least 1.5 times that of the coarse grinding chamber. Since the height of the coarse grinding chamber is between 10-20 mm, and the width of the fine grinding chamber decreases from top to bottom, the maximum width of the fine grinding chamber is between 5-7 mm, and the minimum width is between 2-3 mm. As a result, the speed of soy milk flowing from the coarse grinding chamber into the fine grinding chamber will slow down, thereby causing a flow difference, causing part of the soy milk to accumulate between the coarse grinding chamber and the fine grinding chamber, which will affect the grinding efficiency and even cause blockage. The volume of the buffer chamber is at least 1.5 times that of the coarse grinding chamber. This design allows the buffer chamber to better accommodate the flow difference generated when the soy milk flows into the fine grinding chamber, thereby avoiding soy milk accumulation and blockage.

[0017] Furthermore, an elastic member is provided between the slurry collecting box and the static grinding stone for buffering the force between the two. The elastic member can absorb the impact force between the grinding stone and the slurry collecting box, reduce damage to the grinding stone and the slurry collecting box, and extend their service life.

[0018] Furthermore, the hopper is inserted in the slurry collecting box and extends into the coarse grinding chamber through the static grinding stone. This design allows the soybeans to enter the coarse grinding chamber more evenly, thereby improving the grinding efficiency and soy milk quality. In addition, the hopper can also control the feeding speed of the soybeans, thereby better controlling the time of the grinding process and the quality of the soy milk.

[0019] Furthermore, the driving device is arranged below the slurry collecting box, and its movable end extends into the slurry collecting box and is transmission-connected to the bottom of the movable grinding stone. The driving device provides power by being transmission-connected to the bottom of the movable grinding stone, so that the grinding stone can perform grinding operations in the soy milk, thereby grinding the soy milk into fine soy milk. The driving device can also adjust the rotation speed of the movable grinding stone as needed, so as to better control the time of the grinding process and the quality of the soy milk.

[0020] Furthermore, at least two symmetrical material-dispensing pieces are arranged at the center of the top surface of the movable grinding stone, and the material-dispensing pieces are used to disperse the soybeans coming out of the hopper between the movable grinding stone and the static grinding stone. The setting of the material-dispensing pieces can make the soybeans more evenly distributed between the movable grinding stone and the static grinding stone, thereby improving the grinding efficiency and the soymilk quality.

[0021] Furthermore, a row of pulp pipes is connected to the side wall of the pulp collecting box, which is used to discharge the ground soybean milk from the pulp collecting box for further processing.

[0022] The advantages of the pulping device described in the utility model over the prior art are:

[0023] The utility model describes a refining device, through the design of a static grinding stone and a dynamic grinding stone, so that the plane of the bottom surface of the dynamic grinding stone and the plane of the top surface of the static grinding stone form a coarse grinding chamber, the inclined surface of the dynamic grinding stone and the curved surface of the static grinding stone form a buffer chamber, and the inclined surface of the dynamic grinding stone and the inclined surface of the static grinding stone form a fine grinding chamber; the soybeans flow into the buffer chamber after preliminary refining in the coarse grinding chamber, and then flow into the fine grinding chamber for fine grinding, and at the same time, during the refining process, the buffer chamber can balance the flow between the coarse grinding chamber and the fine grinding chamber; through this design, the utility model can realize continuous refining without stopping, and has the advantages of continuous refining and high refining efficiency.

[0024] The utility model discloses a pulping device, by setting the height of the coarse grinding chamber between 10-20mm, and the width of the fine grinding chamber decreasing from top to bottom, the maximum width of the fine grinding chamber is between 5-7mm, and the minimum width is between 2-3mm, so that the pressure on the soybean milk during the pulping process is gradually increased, so that the soybean milk is continuously finely ground for multiple times during the flow in the fine grinding chamber, so as to more thoroughly separate the protein and starch in the soybean, improve the quality and taste of the soybean milk, and have the advantage of stable quality of the ground soybean milk.

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] Example: Figure 1As shown, a pulping device provided in this embodiment is used for heating soy milk, including a pulp collecting box 1, a static grinding stone 2, and a dynamic grinding stone 3. The pulp collecting box 1 usually has a large capacity, and its outer shell is usually made of materials such as stainless steel or plastic, and has the characteristics of corrosion resistance and durability; the outer shell is usually cylindrical or square, with a certain height and width to accommodate the soy milk and facilitate its use; the bottom of the pulp collecting box 1 is connected to a support frame 15 by bolts, and the support frame 15 plays a stabilizing role in the pulping device.

[0030] Preferably, the static grinding stone 2 is suspended below the bracket 101. The fine grinding stone 2 usually has one or more mounting holes, and the bracket 101 has corresponding holes, and the two are connected by a positioning bolt 12;

[0031] Preferably, the movable grinding stone 3 is rotatably arranged on the inner wall of the lower side of the slurry collecting box 1, and a base 13 is connected to the bottom surface of the movable grinding stone 3 by bolts. The base 13 is used to stabilize the movable grinding stone 3, and the movable grinding stone 3 is transmission-connected to the movable end of the driving device 9 through the base 13.

[0032] Preferably, a row of slurry pipes 11 are connected to the side wall of the slurry collecting box 1, which are used to discharge the ground soy milk from the slurry collecting box 1 for the next step of processing. A valve 14 is provided on one end of the slurry discharge pipe 11 close to the slurry collecting box 1. The valve 14 usually adopts a butterfly valve or a ball valve and its main structure includes a valve body, a valve flap, a sealing gasket and other parts; specifically, the valve 14 is usually connected to the slurry discharge pipe 11 through a threaded connection, and the valve body of the valve 14 is provided with a threaded hole corresponding to the slurry discharge pipe 11, and the valve is fixed to the slurry discharge pipe 11 by bolts; the valve flap of the valve 14 is usually made of elastic material, which can automatically adjust the opening of the valve 14 to control the flow rate of the soy milk. At the same time, the sealing gasket of the valve 14 also plays a sealing role to ensure that the soy milk does not leak.

[0033] Working principle:

[0034] First, raw materials such as soybeans are put into the slurry collecting box 1 through the hopper 8. The hopper design allows the raw materials to directly pass through the static grinding stone 2 into the coarse grinding chamber 4. The driving device 9 is located below the slurry collecting box 1, and the dynamic grinding stone 3 is continuously and stably rotated counterclockwise or clockwise through mechanical connection.

[0035] The upper end of the moving grinding stone 3 is inserted into the inner concave surface of the static grinding stone 2. As the moving grinding stone rotates, the soybeans are squeezed and sheared in the coarse grinding chamber 4 between the two stones, and begin to be initially broken to form a coarse soybean milk. This stage mainly removes the large block structure of the soybeans.

[0036] The coarsely ground soy milk then flows into the buffer chamber 5, which is composed of the inclined surface of the moving grinding stone 3 and the curved surface of the static grinding stone 2. It is designed to have a certain volume for temporarily storing the soy milk and regulating the flow to the next level to avoid insufficient fine grinding caused by excessive instantaneous flow.

[0037] Finally, the soybean milk passes through the fine grinding chamber 6 where the moving grinding stone 3 and the static grinding stone 2 are in contact with each other on the inclined surface. The gap here is smaller than that in the coarse grinding chamber, and the inclination of the moving grinding stone is greater than that of the static grinding stone, which can grind the soybean milk more finely, remove the remaining fine particles, and achieve a fine soybean milk texture. The finely ground soybean milk is discharged through the discharge pipe 11 on the side wall of the collecting box 1 by gravity or auxiliary pump pressure, completing the entire grinding process.

[0038] When multiple illustrative embodiments are mentioned in this specification, it means that the specific structure described in conjunction with the embodiment is included in at least one embodiment generally described in this application. The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment. Further, when a structure is described in conjunction with any embodiment, it is claimed that the structure is implemented in conjunction with other embodiments within the scope of the utility model.
