Description

Technical Field

[0001] The utility model belongs to the technical field of soybean milk powder production, and particularly relates to a raw bean screening device for soybean milk powder production. Background Technique

[0002] The processing procedures of soybean milk powder are bean selection, soaking, pulping, filtering and drying into powder. Since the water absorption and pulp output of raw beans are different due to different particle sizes, the bean selection procedure before soaking is very necessary.

[0003] A patent document with the patent publication number CN219597228U and the patent name of a soybean particle screening device discloses a device for screening raw beans based on a stirring form. The sieve tray of the device is in an open form. When screening raw bean particles, the raw beans are placed on the sieve tray, and the sliding brush rotates and stirs to make the raw beans that meet the size pass through the sieve tray and fall into the lower receiving tray, thus completing the particle screening.

[0004] When the device is screening, it can only screen the raw beans into two categories, and does not realize the refined screening of raw bean particles. The screening effect is limited. At the same time, when the device is screening, it is necessary to limit the addition amount of raw beans. If the addition amount is too large, it is very easy for the raw beans to be stirred by the sliding brush and overflow into the receiving tray without being screened, which is not conducive to the screening process. Content of the Utility Model

[0005] In order to solve the problems existing in the above background technique, the utility model provides a raw bean screening device for soybean milk powder production. The overall structure of the device is simple, the layout is convenient, the screening effect is good and impurities can be removed.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a raw bean screening device for soybean milk powder production, including a base frame, a screening cylinder, a feeding hopper, a driving motor and a plurality of storage tanks. The screening cylinder is rotatably installed in the base frame. The feeding hopper is fixedly arranged at the tail of the base frame. A feeding pipe is arranged at the bottom of the feeding hopper, and the discharging end of the feeding pipe penetrates into the tail of the screening cylinder. A first sprocket is fixedly arranged on the head end face of the screening cylinder. The driving motor is fixedly arranged on the base frame, and a second sprocket is fixedly arranged on the driving end of the driving motor. The second sprocket is connected with the first sprocket through a chain to form a chain drive pair. The driving motor drives the screening cylinder to rotate through the chain drive pair. A plurality of sieve holes with different pore sizes are processed on the cylinder body of the screening cylinder, and a storage tank is placed below each sieve hole with different pore sizes. When the screening cylinder rotates, raw beans of different sizes leak out from the sieve holes with different pore sizes and fall into different storage tanks.

[0007] The screening cylinder is inclined and installed in the base frame, with the tail of the screening cylinder sinking and the head rising. A screw blade is fixedly arranged on the inner wall of the cylinder body of the screening cylinder. When the screening cylinder rotates driven by a drive, the screw blade pushes the raw beans to move upward from bottom to top, and the raw beans are screened during the movement process.

[0008] The screening holes on the cylinder body of the screening cylinder are arranged in sections, and the aperture of the screening holes in each section is the same. The aperture of the screening holes gradually increases from the tail to the head of the screening cylinder. A discharge hole that penetrates through the inside and outside is processed and opened on the cylinder body of the screening cylinder. The discharge hole is arranged near the head of the screening cylinder and is arranged along the screw blade.

[0009] The raw bean screening device for soybean milk powder production further includes an air suction hood, a suction machine and an impurity box. A through hole is opened at the center of the end face of the head of the screening cylinder. The air suction hood penetrates through the through hole and is located on the axis of the screening cylinder. The air inlet of the air suction hood faces vertically downward. The impurity box is placed outside the base frame, and the suction machine is placed on the open upper end of the impurity box. The outlet of the suction machine is inserted into the impurity box, and the inlet of the suction machine is connected to the air suction hood. When the suction machine operates, it sucks the impurities in the screening cylinder through the air suction hood and collects them in the impurity box.

[0010] The beneficial effects of the present utility model: The screening cylinder of the device is relatively closed, and the situation that raw beans overflow without being screened will not occur, ensuring the screening effect; multiple sections of screening holes are arranged on the screening cylinder of the device, and the raw beans can be refined and screened into multiple sizes, with good screening effect; a screw blade is arranged on the inner wall of the screening cylinder, which can transport the raw beans while stirring the raw beans, and multiple functions are realized through a single component, simplifying the device structure; the suction machine and the air suction hood are combined and arranged on the device, which can suck impurities from the raw beans and improve the purity of the raw beans after screening.

A feeding pipe 61 is arranged at the bottom of the loading hopper 6, and the discharging end of the feeding pipe 61 penetrates into the screening cylinder 2 from the tail to supplement the unscreened raw beans for the screening cylinder 2. A first sprocket 21 is fixedly arranged on the head end face of the screening cylinder 2. The driving motor 7 is fixedly arranged on the base frame 1, and a second sprocket is fixedly arranged on the driving end of the driving motor 7. The second sprocket is connected by chain drive with the first sprocket 21 to form a chain drive pair. The driving motor 7 drives the screening cylinder 2 to rotate through the chain drive pair, so that the screening cylinder 2 rotates. A plurality of screening holes 23 with different pore sizes are processed on the barrel body of the screening cylinder 2. A storage tank 5 is placed below each screening hole 23 with different pore sizes. When the screening cylinder 2 rotates, raw beans of different sizes leak out from the screening holes 23 with different pore sizes and fall into different storage tanks 5.

[0018] The screening cylinder 2 is inclined and installed in the base frame 1, with the tail of the screening cylinder 2 sinking and the head rising. A screw blade 22 is fixedly arranged on the inner wall of the barrel body of the screening cylinder 2. When the screening cylinder 2 is driven to rotate, the screw blade 22 pushes the raw beans to move upward from bottom to top, and the raw bean screening is completed during the moving process.

[0019] The screening holes 23 on the barrel body of the screening cylinder 2 are arranged in sections, and the pore sizes of the screening holes 23 in each section are the same. The pore sizes of the screening holes 23 gradually increase from the tail to the head of the screening cylinder 2. A discharge hole 24 that penetrates through the inside and outside is processed on the barrel body of the screening cylinder 2. The discharge hole 24 is arranged near the head of the screening cylinder 2 and is arranged along the pushing surface of the screw blade 22. The raw beans that have not been discharged from the screening cylinder 2 after the screening process are discharged from the discharge hole 24. Arranging the discharge hole 24 along the screw blade 22 can effectively discharge the raw beans in the screening cylinder 2 to avoid residue.

[0020] The raw bean screening device for soybean milk powder production further comprises an air suction hood 3, a suction machine 4 and an impurity box 8. A through hole is opened at the center of the head end face of the screening cylinder 2. The air suction hood 3 is inserted into the screening cylinder 2 from the through hole and is located on the axis of the screening cylinder 2. The air inlet of the air suction hood 3 faces vertically downward. The impurity box 8 is placed outside the base frame 1, and the suction machine 4 is placed on the open upper end of the impurity box 8. The outlet of the suction machine 4 is inserted into the impurity box 8, and the inlet of the suction machine 4 is connected with the air suction hood 3. When the suction machine 4 operates, impurities such as bean skins in the raw beans in the screening cylinder 2 are sucked out through the air suction hood 3 and collected in the impurity box 8.

[0021] In the base frame 1, a bearing 11 is provided on each of the two side walls. When the screening cylinder 2 is mounted in the base frame 1, the two ends of the screening cylinder 2 are respectively inserted into the two bearings 11.

[0022] On the inner wall at the tail end of the base frame 1, a positioning projection 12 is provided.

The suction hood 3 is inserted into the screening cylinder 2, and the positioning groove is buckled on the positioning projection 12 to ensure the stability of the suction hood 3.

[0023] A bracket 9 is provided at the bottom of the loading hopper 6 to maintain the stability of the loading hopper 6. A flow valve is provided on the replenishing pipe 61 to control the replenishing rate of the raw beans.

[0024] Working principle: The unscreened raw beans are loaded into the loading hopper 6. The raw beans enter the screening cylinder 2 through the replenishing pipe 61. The driving motor 7 drives the screening cylinder 2 to rotate through the chain transmission pair. While the auger blade 22 pushes the raw beans to move upward from bottom to top, the raw beans are screened in the order that small particles are screened out first and large particles are screened out later. Finally, the raw beans that are not screened out are discharged from the discharge hole 24 of the screening cylinder 2. The screening cylinder 2 continues to rotate for screening work, and the replenishing pipe 61 continues to add raw beans. If the loading hopper 6 is short of materials, raw beans can be replenished into the loading hopper 6. While the screening cylinder 2 is rotating for screening, the suction machine 4 operates synchronously. The mass of impurities such as pods mixed in the raw beans is less than that of the raw bean grains. The suction machine 4 can suck out the impurities through the suction hood 3 and collect them in the impurity box 8. The screening cylinder 2 is detachably installed, and a screening cylinder 2 with different pore diameters of the screening holes 23 can be selected according to different raw beans.
