Description

Technical Field

[0001] This invention relates to the field of soybean grinding technology, specifically to a soybean protein particle grinding equipment and grinding process. Background Technology

[0002] Soy protein is a plant-based protein, and a complete plant-based protein. Nutritionally, it is comparable to animal protein and is considered one of the most nutritious plant proteins. Soy protein particles require grinding during processing.

[0003] The existing technology still has the following shortcomings in practical use:

[0004] In the existing technology, the grinding gap of the grinding equipment is constant, which makes it inconvenient to adjust the grinding gap. This makes it difficult to grind soybean powder of different fineness. At the same time, the grinding sleeve of the grinding equipment is prone to high temperature during the grinding of soybean protein particles. The existing technology does not make it convenient to cool it down. High temperature can easily cause the ground soybean protein particles to denature.

[0005] Existing grinding equipment involves pouring large amounts of soybean raw materials into the equipment, which makes it difficult to feed the material evenly. This can easily lead to blockages during the grinding process, resulting in poor grinding performance.

[0006] Therefore, we propose a soybean protein particle grinding equipment and grinding process. Summary of the Invention

[0016] Preferably, the bottom of the left and right side walls of the grinding box are symmetrically connected to two fixed seats, and the lower end face of the fixed seats is fixedly connected to a support leg.

[0017] A grinding process for a soybean protein particle grinding device, the process using the aforementioned soybean protein particle grinding device, includes the following steps:

[0018] S1: Adjust the gap between the grinding sleeve and the grinding block according to the required grinding fineness, start the telescopic cylinder to make the connecting plate drive the connecting rod and the connecting plate to move, thereby making the spline shaft move up and down, and thus adjusting the grinding gap between the grinding block and the grinding sleeve;

[0019] S2: Start the first motor. The first motor causes the rotating shaft to drive the crushing blade to rotate, thereby crushing the soybeans. The crushed soybeans fall into the conveying pipe through the first and second filter screens. At the same time, the rotating shaft drives the lever to rotate through the transmission component, thereby causing the lever to move the second filter screen horizontally. After the second filter screen moves, it is horizontally misaligned with the first filter screen, thereby squeezing and crushing the soybean particles stuck in the first and second filter screens. Then, the push rod is inserted into the first and second filter screens to push out the crushed soybean particles, further improving the passability of the first and second filter screens. Start the second motor. The output shaft of the second motor drives the screw to rotate, evenly conveying the crushed soybean particles that have fallen into the conveying pipe into the grinding sleeve.

[0020] S3: Start the third motor to make the assembly shaft and drive gear rotate. The rotation of the drive gear drives the rotating sleeve and spline shaft to rotate, which in turn makes the grinding block rotate, thereby grinding the soybean particles. The ground soybean powder falls to the bottom of the grinding box through the outlet of the grinding sleeve.

[0021] S4: In step three, the rotation of the assembly shaft can also drive the driving bevel gear, driven bevel gear, transmission shaft and driving pulley to rotate. The driving pulley drives the driven pulley to rotate through the third synchronous belt. The rotation of the driven pulley causes the connecting shaft and rotating rod to rotate. The rotation of the rotating rod drives the mating rod to move, which in turn drives the connecting shaft and piston to reciprocate, thereby drawing water from the storage tank into the distribution pipe and then spraying it onto the outer wall of the grinding sleeve through the spray pipe, thereby cooling the grinding sleeve. The dripping water is filtered through the filter screen and flows into the storage tank through the return pipe. During grinding, the grinding sleeve can be cooled.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] By setting up a grinding sleeve, grinding block, rotating sleeve, splined shaft, connecting plate, connecting rod, connecting piece and telescopic cylinder, the gap between the upper and lower grinding components can be automatically adjusted, which can facilitate grinding soybean powder of different fineness, ensure the best grinding effect, and solve the problem of inconvenience in adjusting the grinding gap in the existing technology;

[0024] By setting up cooling and power structures, water is sprayed to cool the grinding jacket while grinding, avoiding high temperature in the grinding jacket. This effectively cools the grinding process and prevents soybean protein from denaturing or being damaged due to overheating, solving the problem that high temperature during grinding can easily cause soybean denaturation in existing technologies.

[0025] The feeding structure enables the uniform crushing of soybean particles and the uniform feeding of the crushed soybean particles into the grinding equipment. Continuous and uniform feeding avoids clogging and improves the grinding effect of soybean protein particles. This solves the problem in the existing technology where feeding a large amount of soybeans at once can easily cause clogging and reduce the grinding effect. Attached Figure Description

[0045] A grinding process for a soybean protein particle grinding device, the process using the aforementioned soybean protein particle grinding device, includes the following steps:

[0046] S1: Adjust the gap between the grinding sleeve 3 and the grinding block 9 according to the required grinding fineness, start the telescopic cylinder 13 to make the connecting plate 12 drive the connecting rod 11 and the connecting plate 10 to move, thereby making the spline shaft 8 move up and down, and thus adjust the grinding gap between the grinding block 9 and the grinding sleeve 3.

[0047] S2: Start the first motor 605. The first motor 605 causes the rotating shaft 606 to drive the crushing blade 607 to rotate, thereby crushing the soybeans. The crushed soybeans fall into the conveying pipe 6020 through the first filter screen 603 and the second filter screen 604. At the same time, the rotating shaft 606 drives the lever 609 to rotate through the transmission component 608, thereby causing the lever 609 to move the second filter screen 604 horizontally. After the second filter screen 604 moves, it is horizontally misaligned with the first filter screen 603, thereby squeezing and crushing the soybean particles stuck in the first filter screen 603 and the second filter screen 604. Then, the push rod 6019 is inserted into the first filter screen 603 and the second filter screen 604 to push out the crushed soybean particles, further improving the passability of the first filter screen 603 and the second filter screen 604. Start the second motor 6021. The output shaft of the second motor 6021 drives the screw 6022 to rotate, which evenly conveys the crushed soybean particles that have fallen into the conveying pipe 6020 to the grinding sleeve 3.

[0048] S3: Start the third motor 1402 to make the assembly shaft 1403 and the drive gear 1404 rotate. The rotation of the drive gear 1404 drives the rotating sleeve 7 and the spline shaft 8 to rotate, which in turn makes the grinding block 9 rotate, thereby grinding the soybean particles. The ground soybean powder falls to the bottom of the grinding box 1 through the outlet of the grinding sleeve 3.

[0049] S4: In step three, the rotation of the assembly shaft 1403 can also drive the drive bevel gear 1405, the driven bevel gear 1408, the transmission shaft 1407 and the drive pulley 1409 to rotate. The drive pulley 1409 drives the driven pulley 4011 to rotate through the third synchronous belt 1410. The rotation of the driven pulley 4011 causes the connecting shaft 4010 and the rotating rod 4012 to rotate. The rotation of the rotating rod 4012 drives the mating rod 4013 to move, which in turn drives the connecting shaft 404 and the piston 405 to reciprocate, thereby drawing water from the storage tank 401 back and forth and delivering it to the diversion pipe 407. Then, the water is sprayed onto the outer wall of the grinding sleeve 3 through the spray pipe 409, thereby cooling the grinding sleeve 3. The dripping water is filtered by the filter screen 4017 and flows into the storage tank 401 through the return pipe 4014. During grinding, the grinding sleeve 3 can be cooled.

[0050] Working principle: First, adjust the gap between the grinding sleeve 3 and the grinding block 9 according to the required grinding fineness. Then, activate the telescopic cylinder 13 to move the connecting plate 12, which in turn moves the connecting rod 11 and the connecting plate 10, causing the spline shaft 8 to move up and down. This adjusts the grinding gap between the grinding block 9 and the grinding sleeve 3. Next, pour soybeans into the crushing box 602 and start the first motor 605. The output shaft of the first motor 605 drives the rotating shaft 606 to rotate the crushing blade 607. As the crushing blade 607 rotates, it crushes the soybeans in the crushing box 602. The crushed soybean particles fall through the first filter screen 603 and the second filter screen 604 into the conveying pipe 6020. Then, start the second motor 6021. The output shaft of the second motor 6021 drives... The screw 6022 rotates, evenly conveying the crushed soybean particles falling into the conveying pipe 6020 to the grinding sleeve 3. Meanwhile, the rotating shaft 606 drives the first helical gear in the transmission assembly 608 to rotate. The first helical gear, through the second helical gear, drives the rotating shaft to rotate. The rotating shaft drives several levers 609 to rotate. When the levers 609 rotate, they contact and compress the convex shaft inside the fork-shaped frame 6011, thereby causing the fork-shaped frame 6011 to drive the T-shaped frame 6010 to move away from the crushing box 602. The T-shaped frame 6010 drives the second filter screen 604 to move horizontally. At this time, the second filter screen 604 is horizontally misaligned with the first filter screen 603, thus crushing and grinding the soybean particles stuck between the first filter screen 603 and the second filter screen 604, preventing... To prevent the first filter screen 603 and the second filter screen 604 from becoming clogged, the first elastic element between the T-shaped frame 6010 and the grinding box 602 extends, and the second filter screen 604 drives the L-shaped rod 6012 to slide in the translation groove. The L-shaped rod 6012 drives the first sealing plate 6013 to continuously seal the translation groove, thereby preventing soybeans in the grinding box 602 from leaking out through the translation groove. At the same time, the L-shaped rod 6012 drives the roller to move. After the roller moves, it contacts and squeezes the lever 6015. The lever 6015 is subjected to force and rotates around the connection of the rotating rod 6014. At this time, the second elastic element between the lever 6015 and the rotating rod 6014 is subjected to force and contracts. After the roller continues to move, it no longer contacts the lever 6015. After the lever 6015 is released from the restriction, it passes through the first... After the two elastic elements release and rotate to reset, several levers 609 continue to rotate and no longer contact the convex shaft inside the fork-shaped frame 6011. The fork-shaped frame 6011 then disengages, allowing the second filter screen 604 to move. At this time, the first elastic element between the T-shaped frame 6010 and the crushing box 602 contracts, causing the T-shaped frame 6010 to quickly slide and reset. The T-shaped frame 6010 then causes the second filter screen 604 to quickly reset against the fork-shaped frame 6011. The second filter screen 604 then causes the L-shaped rod 6012 to quickly reset. The L-shaped rod 6012 causes the roller to reset and contact and press against the lever block 6015. At this time, the lever block 6015 is restricted by the protruding plate and cannot rotate. The lever block 6015 will then press against the protruding plate, causing the rotating rod 6014 to rotate. After rotating, one end of the rotating rod 6014 tilts upwards.The protruding shaft of the sliding rod 6016 contacts and presses against it. The pressure on the protruding shaft causes the sliding rod 6016 to slide upwards along the vertical groove. The sliding rod 6016 then causes the second sealing plate 6017 and the perforated frame 6018 to slide upwards. The second sealing plate 6017 can consistently seal the vertical groove, preventing soybeans in the crushing box 602 from leaking out through the groove. The perforated frame 6018 causes the top rod 6019 to slide upwards. After sliding, the top rod 6019 inserts into the first filter screen 603 and the second filter screen 604, thereby pushing out the soybean particles stuck in the first filter screen 603 and the second filter screen 604, further... To prevent soybean particles from getting stuck in the first filter screen 603 and the second filter screen 604, which would reduce their throughput, the ejected soybean particles would be further crushed by the crushing blade 607. After the roller continues to move and resets, it no longer contacts the paddle block 6015. Once the paddle block 6015 is released from its restraints, the rotating rod 6014 can move. At this time, the sliding rod 6016 slides back to its original position due to gravity, along with the push rod 6019. After resetting, the push rod 6019 moves away from the first filter screen 603 and the second filter screen 604. Simultaneously, the rotating rod 6014 rotates, causing the paddle block 6015 to rotate and reset, thus completing the crushing of the soybean particles. After initial crushing, the third motor 1402 is started, causing the assembly shaft 1403 and the drive gear 1404 to rotate. The rotation of the drive gear 1404 drives the rotating sleeve 7 and the splined shaft 8 to rotate, which in turn causes the grinding block 9 to rotate, thus grinding the soybean particles. The ground soybean powder falls to the bottom of the grinding box 1 through the outlet of the grinding sleeve 3. At the same time, the rotation of the assembly shaft 1403 also drives the drive bevel gear 1405, the driven bevel gear 1408, the transmission shaft 1407, and the drive pulley 1409 to rotate. The drive pulley 1409 drives the driven pulley 4011 through the third synchronous belt 1410. The driven pulley 4011 rotates, causing the connecting shaft 4010 and the rotating rod 4012 to rotate. The rotation of the rotating rod 4012 drives the mating rod 4013 to move, which in turn drives the connecting shaft 404 and the piston 405 to reciprocate. This reciprocating motion draws water from the storage tank 401 into the distribution pipe 407, and then sprays it onto the outer wall of the grinding sleeve 3 through the spray pipe 409, thus cooling the grinding sleeve 3. The dripping water is filtered by the filter screen 4017 and flows back into the storage tank 401 through the return pipe 4014. This process effectively cools the grinding sleeve 3 during grinding.

The grinding process of a soybean protein particle grinding equipment according to claim 6, characterized in that, Includes the following steps: S1: Adjust the gap between the grinding sleeve (3) and the grinding block (9) according to the required grinding fineness, start the telescopic cylinder (13) to make the connecting plate (12) drive the connecting rod (11) and the connecting plate (10) to move, thereby making the spline shaft (8) move up and down, and thus adjust the grinding gap between the grinding block (9) and the grinding sleeve (3); S2: Start the first motor (605). The first motor (605) causes the rotating shaft (606) to drive the crushing blade (607) to rotate, thereby crushing the soybeans. The crushed soybeans fall into the conveying pipe (6020) through the first filter screen (603) and the second filter screen (604). At the same time, the rotating shaft (606) drives the lever (609) to rotate through the transmission assembly (608), thereby causing the lever (609) to drive the second filter screen (604) to move horizontally. After the second filter screen (604) moves, it is horizontally misaligned with the first filter screen (603). This crushes the soybean particles stuck in the first filter screen (603) and the second filter screen (604). Then, the push rod (6019) is inserted into the first filter screen (603) and the second filter screen (604) to push out the crushed soybean particles, further improving the passability of the first filter screen (603) and the second filter screen (604).

S3: Start the third motor (1402) to make the assembly shaft (1403) and the drive gear (1404) rotate. The rotation of the drive gear (1404) drives the rotating sleeve (7) and the spline shaft (8) to rotate, which in turn makes the grinding block (9) rotate, thereby grinding the soybean particles. The ground soybean powder falls to the bottom of the grinding box (1) through the outlet of the grinding sleeve (3). S4: In step S3, the rotation of the assembly shaft (1403) can also drive the driving bevel gear (1405), the driven bevel gear (1408), the transmission shaft (1407), and the driving pulley (1409) to rotate. The driving pulley (1409) drives the driven pulley (4011) to rotate via the third synchronous belt (1410). The rotation of the driven pulley (4011) causes the connecting shaft (4010) and the rotating rod (4012) to rotate. The rotation of the rotating rod (4012) drives the mating rod (4010) to rotate. 13) The movement drives the connecting shaft (404) and piston (405) to reciprocate, thereby drawing water from the storage tank (401) into the distribution pipe (407), and then spraying the water onto the outer wall of the grinding sleeve (3) through the spray pipe (409), thereby cooling the grinding sleeve (3). The dripping water is filtered by the filter screen (4017) and flows into the storage tank (401) through the return pipe (4014). The grinding sleeve (3) can be cooled while grinding.
