Description

Technical Field

[0001] This invention relates to the technical field of brewing, and in particular to a device for crushing koji blocks used in brewing. Background Art

[0002] In the brewing process, the yeast needs to be compressed into blocks for convenient transportation and storage. During the use of the yeast, in order to better achieve uniform mixing and stirring of the yeast and grain raw materials, the block yeast needs to be crushed by a crushing device. Existing technologies for crushing starter culture blocks for brewing include, for example, a baijiu (Chinese liquor) brewing starter culture crushing device and brewing process disclosed in Chinese invention application CN115921069A. This invention utilizes a sieve plate, a drive motor, a first gear, a second gear, a movable rod, a mounting frame, and a grinding roller in coordination to screen and re-grind incompletely crushed starter culture blocks. This allows the device to simultaneously crush the starter culture blocks and re-screen and grind smaller blocks. The multi-stage crushing process improves the efficiency and effectiveness of starter culture crushing, thus benefiting the use of the starter culture blocks.

[0003] However, the existing technology uses a crushing mechanism composed of crushing rollers and other structures. The yeast blocks pass through the crushing mechanism under the action of gravity, resulting in a short crushing time for the yeast blocks and large crushed pieces. The yeast blocks still need to be ground later, making the structure of the crushing device relatively complex. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a brewing koji block crushing device that reciprocates to pierce and crush koji blocks without grinding, has a simpler crushing structure, and is more practical.

[0005] This invention discloses a device for crushing yeast starter for brewing, comprising a shell, a feeding hopper, and a sieve plate. The shell contains a crushing chamber. A feeding port is located on the upper surface of the shell, and a discharge port is located on the lower surface. Both the feeding port and the discharge port communicate with the crushing chamber. The feeding hopper is installed on the feeding port of the shell, and the sieve plate is installed on the discharge port of the shell. The device also includes a lifting mechanism, a pressure plate, and multiple pins. The lifting mechanism is installed at the bottom of the shell and has a lifting rod. The lifting mechanism drives the lifting rod to reciprocate, with the lifting rod extending from below through the sieve plate into the crushing chamber of the shell. The pressure plate is horizontally mounted on the lifting rod, and the upper ends of the multiple pins are vertically mounted on the pressure plate. The pressure plate and the multiple pins are located within the crushing chamber of the shell, with the multiple pins positioned above the sieve plate and having pointed lower ends. The yeast blocks are added to the crushing chamber of the shell through the feeding hopper. The sieve plate blocks the yeast blocks. The lifting mechanism drives the lifting rod to move up and down repeatedly. The lifting rod drives the pressure plate and multiple needles to move up and down repeatedly. When the pressure plate drives the multiple needles to descend, the tips of the multiple needles pierce and crush the yeast blocks on the sieve plate. When the pressure plate drives the multiple needles to rise, the multiple needles detach from the yeast blocks. The multiple needles repeatedly pierce the yeast blocks, thus crushing them. The multiple needles do not shear the yeast blocks, which can reduce the breakage of fibers in the yeast blocks. The yeast blocks crushed to the appropriate size are discharged from the discharge port of the shell through the multiple sieve holes of the sieve plate. The tips of the multiple needles passing through the multiple sieve holes of the sieve plate can avoid clogging of the sieve holes. There is no need for subsequent grinding of the yeast blocks. The structure of crushing yeast blocks is simpler and more practical.

[0006] Preferably, it further includes multiple protruding ends, a second pressure plate, springs, multiple sleeves, multiple steel plates, and multiple spring plates. The first pressure plate is horizontally slidably mounted on the lifting rod of the lifting mechanism. The lower ends of the multiple pins are all provided with protruding ends. The second pressure plate is mounted on the lifting rod of the lifting mechanism, and the second pressure plate is located below the first pressure plate. The upper end of the spring is connected to the first pressure plate, and the lower end of the spring is connected to the second pressure plate. The multiple sleeves are mounted on the second pressure plate, and the multiple sleeves are respectively sleeved on the outside of the multiple pins. The lower ends of the multiple sleeves are circumferentially hinged to multiple steel plates. The upper ends of the multiple steel plates are provided with spring plates. The elastic force of the multiple spring plates causes the lower ends of the multiple steel plates to be tightly pressed against the outer walls of the multiple protruding ends. The inner walls of the lower ends of the multiple steel plates are all provided with wedge-shaped platforms that match the upper end faces of the protruding ends. The lowering rod of the lifting mechanism lowers the second pressure plate. The second pressure plate, driven by a spring, lowers the first pressure plate and multiple pins simultaneously, allowing multiple protruding ends, along with their outer steel plates, to pass through the yeast block. The lower ends of the pins are blocked by the sieve plate. The lifting mechanism's lifting rod continues to lower the second pressure plate, stretching the spring. The second pressure plate then drives multiple sleeves and steel plates to continue descending. The wedge-shaped platforms at the lower ends of the steel plates intersect with the upper surfaces of the protruding ends, causing the steel plates to open outwards from the protruding ends, thus breaking the yeast block from the inside out and improving the yeast's crushing effect. The lifting mechanism's lifting rod rises, causing the pins to disengage from the sieve plate. The spring force pulls the first pressure plate downwards, causing the steel plates to descend relative to the pins. The spring force keeps the lower ends of the steel plates pressed tightly against the outer walls of the protruding ends, resulting in good practicality.

[0007] Preferably, it also includes multiple nuts, with the upper ends of multiple pins passing through the pressure plate. The multiple nuts are rotatably screwed onto the multiple pins, and the multiple nuts lock the multiple pins onto the pressure plate. After adjusting the relative positions of the multiple pins and the pressure plate, the multiple nuts are tightened to lock the multiple pins onto the pressure plate, thereby adjusting the relative distance between the lower ends of the multiple pins and the sieve plate. It is suitable for yeast blocks of different heights and has good versatility.

[0008] Preferably, the device also includes multiple storage slots, with multiple storage slots provided on the outer walls of the multiple protruding ends, and the lower ends of the multiple steel sheets are respectively stored in the multiple storage slots; after the lower ends of the multiple steel sheets are attached to the outer walls of the multiple protruding ends, the multiple steel sheets are respectively stored in the multiple storage slots, thereby improving the neatness of the device.

[0009] Preferably, it also includes a baffle plate, which is installed above the sieve plate by a bracket. The baffle plate is provided with multiple through holes, which are respectively aligned with multiple protruding ends. When the lifting rod of the lifting mechanism is raised, the multiple pins and multiple protruding ends are raised along the multiple through holes of the baffle plate. The baffle plate peels off the residual yeast blocks on the multiple pins and multiple protruding ends, improving practicality.

[0010] Preferably, it also includes an extrusion block and a surrounding plate. The upper part of the crushing chamber of the shell is conical. The extrusion block is installed on the lifting rod of the lifting mechanism. The outer wall of the extrusion block has the same taper as the upper part of the crushing chamber of the shell. The surrounding plate is set on the upper inner wall of the crushing chamber of the shell. When the extrusion block is in a low position, the inner edge of the surrounding plate is aligned with the lower edge of the extrusion block. When the yeast block is fed into the crushing chamber of the shell through the feeding hopper, the yeast block enters between the extrusion block and the upper inner wall of the shell. The surrounding plate blocks the yeast block. When the lifting rod of the lifting mechanism rises, it pushes the extrusion block to rise. The outer wall of the extrusion block approaches the conical inner wall of the shell, thereby performing preliminary extrusion and crushing of the yeast block. When the lifting rod of the lifting mechanism falls, the preliminarily crushed yeast block falls onto the sieve plate through the gap between the extrusion block and the surrounding plate. It has good practicality.

[0011] Preferably, it also includes a crushing ring, which is installed on the conical inner wall of the upper part of the crushing chamber of the shell. The crushing ring is provided with multiple crushing racks, which are aligned with the outer wall of the extrusion block. By setting the crushing ring, the initial crushing effect of the extrusion block and the conical inner wall of the shell on the yeast block is improved.

[0012] Preferably, it also includes a circular screen, a push rod, a support rod, and an ear plate. The circular screen is rotatably mounted on the lower end face of the screen plate. Multiple screen holes on the circular screen are aligned with multiple screen holes on the screen plate. A first protrusion is provided on the upper end face of the circular screen, and a second protrusion is provided on the lower end face of the screen plate. The first and second protrusions align and collide. The push rod is mounted on the lifting rod of the lifting mechanism. The inner end of the support rod is rotatably connected to the outer end of the push rod, and the outer end of the support rod is rotatably connected to the ear plate. The ear plate is mounted on the lower end face of the circular screen. When the lifting rod of the lifting mechanism rises, the push rod... The rod pushes the circular screen disc to rotate at a certain angle through the support rod, causing protrusion one and protrusion two to collide. When the lifting rod of the lifting mechanism descends, the push rod pulls the circular screen disc to rotate in the opposite direction at a certain angle through the support rod, causing protrusion one and protrusion two to collide and vibrate the screen plate, causing the circular screen disc to rotate back and forth. This causes multiple screen holes on the circular screen disc to align and intermittently with multiple screen holes on the screen plate. When multiple screen holes on the circular screen disc align with multiple screen holes on the screen plate, the lower ends of multiple pins pass through the screen holes on the screen plate and the circular screen disc, which is practical.

[0013] Preferably, it also includes a receiving hopper, which is installed at the bottom of the shell and located below the discharge port of the shell; the receiving hopper catches the broken pieces of yeast that are discharged through the discharge port of the shell and guides them out, which is practical.

[0014] Preferably, the device also includes a pusher plate and a pusher rod. The upper end of the pusher plate is rotatably installed in the receiving hopper, and the lower end of the pusher plate blocks the output port of the receiving hopper. The lower end of the pusher rod is rotatably connected to the pusher plate, and the upper end of the pusher rod is rotatably connected to the lifting rod of the lifting mechanism. When the lifting rod of the lifting mechanism rises, the lifting rod pulls the lower end of the pusher plate upwards and inwards in the receiving hopper through the pusher rod, thereby opening the output port of the receiving hopper. When the lifting rod of the lifting mechanism falls, the lifting rod pushes the lower end of the pusher plate downwards and inwards in the receiving hopper through the pusher rod, thereby pushing the pusher plate out of the output port of the receiving hopper, improving the discharge efficiency.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: multiple needles repeatedly pierce the yeast block to break it up; the multiple needles do not shear the yeast block, which can reduce the breakage of fibers in the yeast block; the yeast block crushed to a suitable size is discharged from the outlet of the shell through multiple sieve holes of the sieve plate; the tips of multiple needles passing through multiple sieve holes of the sieve plate can avoid sieve hole blockage; there is no need to grind the yeast block later; the structure of crushing yeast block is simpler and more practical.

[0029] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. Example 1

[0030] like Figures 1 to 4 , Figures 6 to 10As shown, a device for crushing brewing koji blocks includes a shell 1, a feeding hopper 2, and a sieve plate 3. The shell 1 has a crushing chamber inside, a feeding port on its upper surface, and a discharge port on its lower surface. Both the feeding port and the discharge port are connected to the crushing chamber. The feeding hopper 2 is installed on the feeding port of the shell 1, and the sieve plate 3 is installed on the discharge port of the shell 1. The device also includes a lifting mechanism 4, a pressure plate 5, and multiple pins 6. The lifting mechanism 4 is installed at the bottom of the shell 1 and has a lifting rod. The lifting mechanism 4 drives the lifting rod to reciprocate up and down. The pressure plate 5 extends through the sieve plate 3 into the crushing chamber of the housing 1. The pressure plate 5 is horizontally mounted on the lifting rod. The upper ends of multiple pins 6 are vertically mounted on the pressure plate 5. The pressure plate 5 and the multiple pins 6 are located in the crushing chamber of the housing 1, with the pins 6 positioned above the sieve plate 3 and their lower ends being pointed. The system also includes multiple protruding ends 7, a second pressure plate 8, springs 9, multiple sleeves 10, multiple steel plates 11, and multiple spring plates 12. The pressure plate 5 is horizontally slidably mounted on the lifting rod of the lifting mechanism 4. The lower ends of the multiple pins 6 are all provided with protruding ends 7. The pressure plate 8 is mounted on... On the lifting rod of the lifting mechanism 4, pressure plate 2 8 is located below pressure plate 1 5. The upper end of spring 9 is connected to pressure plate 1 5, and the lower end of spring 9 is connected to pressure plate 2 8. Multiple sleeves 10 are installed on pressure plate 2 8, and the multiple sleeves 10 are respectively sleeved on the outside of multiple pins 6. The lower ends of the multiple sleeves 10 are circumferentially hinged to multiple steel plates 11. The upper ends of the multiple steel plates 11 are provided with spring plates 12. The elasticity of the multiple spring plates 12 causes the lower ends of the multiple steel plates 11 to be tightly pressed against the outer wall of the multiple protruding ends 7. The inner wall of the lower end of the multiple steel plates 11 is provided with the upper end of the protruding end 7. The device includes a wedge-shaped platform with matching end faces; it also includes multiple nuts 13, with the upper ends of multiple pins 6 passing through the pressure plate 5, and the multiple nuts 13 being rotatably screwed onto the multiple pins 6, thus locking the multiple pins 6 onto the pressure plate 5; it also includes multiple receiving grooves 14, with multiple receiving grooves 14 provided on the outer walls of multiple protruding ends 7, and the lower ends of multiple steel sheets 11 being stored in the multiple receiving grooves 14; it also includes a baffle 15, which is mounted above the screen plate 3 via a bracket, and the baffle 15 is provided with multiple through holes, which are respectively aligned with the multiple protruding ends 7.

[0031] After adjusting the relative positions of the multiple pins 6 and the pressure plate 5, tighten the multiple nuts 13 to lock the multiple pins 6 onto the pressure plate 5, thereby adjusting the relative distance between the lower ends of the multiple pins 6 and the sieve plate 3. This is suitable for yeast blocks of different heights. The yeast blocks are added into the crushing chamber of the shell 1 through the feeding hopper 2. The sieve plate 3 blocks the yeast blocks. The lifting mechanism 4 drives the lifting rod to move up and down repeatedly. The lifting rod of the lifting mechanism 4 descends, causing the pressure plate 8 to descend. The pressure plate 8, through the spring 9, drives the pressure plate 5 and the multiple pins 6 to descend synchronously, so that the multiple protruding ends 7, together with the multiple steel plates 11 on their outer sides, pass through the yeast. The lower ends of the multiple pins 6 are blocked by the sieve plate 3. The lifting rod of the lifting mechanism 4 continues to lower the pressure plate 8, causing the spring 9 to be stretched. The pressure plate 8 drives the multiple sleeves 10 and multiple steel plates 11 to continue to descend. The wedge-shaped platform at the lower end of the multiple steel plates 11 intersects with the upper end face of the multiple protruding ends 7, causing the multiple steel plates 11 to open outwards from the multiple protruding ends 7, thereby breaking the yeast block from the inside out and improving the crushing effect of the yeast. The lifting rod of the lifting mechanism 4 rises, causing the multiple pins 6 to disengage from the sieve plate 3. The elastic force of the spring 9 pulls the pressure plate 5 downwards, causing the multiple As the steel plates 11 descend relative to the multiple pins 6, the elastic force of the multiple spring plates 12 presses the lower ends of the steel plates 11 tightly against the outer walls of the multiple protruding ends 7. After the lower ends of the steel plates 11 are pressed tightly against the outer walls of the multiple protruding ends 7, the steel plates 11 are respectively stored in the multiple storage slots 14. When the lifting rod of the lifting mechanism 4 rises, the multiple pins 6 and the multiple protruding ends 7 rise along the multiple through holes of the baffle 15. The baffle 15 peels off the residual yeast blocks on the multiple pins 6 and the multiple protruding ends 7. The lifting rod drives the pressure plate 5 and the multiple pins 6 to move up and down repeatedly. When the pressure plate 5 drives the multiple pins... When the 6th pin descends, the tips of the multiple pins 6 pierce and break the yeast blocks on the sieve plate 3. When the pressure plate 5 drives the multiple pins 6 to rise, the multiple pins 6 detach from the yeast blocks. The multiple pins 6 repeatedly pierce the yeast blocks, thereby breaking them. The multiple pins 6 do not shear the yeast blocks, which can reduce the breakage of fibers in the yeast blocks. The yeast blocks that have been crushed to a suitable size are discharged from the discharge port of the shell 1 through the multiple sieve holes of the sieve plate 3. The tips of the multiple pins 6 passing through the multiple sieve holes of the sieve plate 3 can avoid sieve hole blockage. There is no need to grind the yeast blocks later, and the structure for crushing yeast blocks is simpler. Example 2

[0032] like Figures 1 to 5As shown, based on Embodiment 1, it also includes an extrusion block 16 and a surrounding plate 17. The upper part of the crushing chamber of the housing 1 is conical. The extrusion block 16 is installed on the lifting rod of the lifting mechanism 4. The outer wall of the extrusion block 16 has the same taper as the upper part of the crushing chamber of the housing 1. The surrounding plate 17 is set on the inner wall of the upper part of the crushing chamber of the housing 1. When the extrusion block 16 is in a low position, the inner edge of the surrounding plate 17 is aligned and in contact with the lower edge of the extrusion block 16. It also includes a crushing ring 18, which is installed on the conical inner wall of the upper part of the crushing chamber of the housing 1. The crushing ring 18 is provided with multiple crushing racks, which are aligned with the outer wall of the extrusion block 16.

[0033] When the yeast starter blocks are fed into the crushing chamber of the shell 1 through the feeding hopper 2, the yeast starter blocks enter between the extrusion block 16 and the upper inner wall of the shell 1. The surrounding plate 17 blocks the yeast starter blocks. When the lifting rod of the lifting mechanism 4 rises, it pushes the extrusion block 16 to rise. The outer wall of the extrusion block 16 approaches the conical inner wall of the shell 1, thereby performing preliminary extrusion and crushing of the yeast starter blocks. When the lifting rod of the lifting mechanism 4 falls, the preliminarily crushed yeast starter blocks fall onto the screen plate 3 through the gap between the extrusion block 16 and the surrounding plate 17. The crushing ring 18 is set to improve the preliminary crushing effect of the extrusion block 16 and the conical inner wall of the shell 1 on the yeast starter blocks. Example 3

[0034] like Figure 1 , Figure 2 , Figure 11 and Figure 12 As shown, based on Embodiment 1, it also includes a circular sieve disc 19, a push rod 20, a support rod 21, and an ear plate 22. The circular sieve disc 19 is rotatably mounted on the lower end face of the sieve plate 3. The multiple sieve holes of the circular sieve disc 19 are matched and aligned with the multiple sieve holes of the sieve plate 3. A protrusion 1 is provided on the upper end face of the circular sieve disc 19, and a protrusion 2 is provided on the lower end face of the sieve plate 3. The protrusion 1 and the protrusion 2 are aligned and collide. The push rod 20 is mounted on the lifting rod of the lifting mechanism 4. The inner end of the support rod 21 is rotatably connected to the outer end of the push rod 20, and the outer end of the support rod 21 is connected to the outer end of the push rod 20. The ear plate 22 is rotatably connected and installed on the lower end face of the circular screen plate 19; it also includes a receiving hopper 23, which is installed at the bottom of the housing 1 and located below the discharge port of the housing 1; it also includes a pusher plate 24 and a pusher rod 25, the upper end of the pusher plate 24 is rotatably installed in the receiving hopper 23, the lower end of the pusher plate 24 blocks the output port of the receiving hopper 23, the lower end of the pusher rod 25 is rotatably connected to the pusher plate 24, and the upper end of the pusher rod 25 is rotatably connected to the lifting rod of the lifting mechanism 4.

[0035] When the lifting rod of the lifting mechanism 4 rises, the push rod 20 pushes the circular screen plate 19 to rotate a certain angle through the support rod 21, causing protrusion one and protrusion two to collide. When the lifting rod of the lifting mechanism 4 falls, the push rod 20 pulls the circular screen plate 19 to rotate in the opposite direction by a certain angle through the support rod 21, causing protrusion one and protrusion two to collide and vibrate the screen plate 3, causing the circular screen plate 19 to rotate back and forth. This causes the multiple screen holes of the circular screen plate 19 to intermittently align and intersect with the multiple screen holes of the screen plate 3. When the multiple screen holes of the circular screen plate 19 are aligned with the multiple screen holes of the screen plate 3, the lower ends of the multiple pins 6 pass through the screen plate 3 and the circular screen plate. The 19-inch sieve is practical. The receiving hopper 23 catches and guides the broken pieces of yeast that are discharged from the outlet of the shell 1. When the lifting rod of the lifting mechanism 4 rises, the lifting rod pulls the lower end of the push plate 24 towards the inside and upward of the receiving hopper 23 through the push rod 25, so that the outlet of the receiving hopper 23 opens. When the lifting rod of the lifting mechanism 4 falls, the lifting rod pushes the lower end of the push plate 24 towards the inside and downward of the receiving hopper 23 through the push rod 25, so that the push plate 24 pushes the broken pieces of yeast in the receiving hopper 23 out of the outlet of the receiving hopper 23, thus improving the discharge efficiency.

[0036] like Figures 1 to 12As shown, the brewing koji block crushing device of the present invention, during operation, firstly, koji blocks are added to the crushing chamber of the shell 1 through the feeding hopper 2. The koji blocks enter between the extrusion block 16 and the upper inner wall of the shell 1, and the surrounding plate 17 blocks the koji blocks. The lifting mechanism 4 drives the lifting rod to move up and down reciprocally. When the lifting rod of the lifting mechanism 4 rises, it pushes the extrusion block 16 to rise. The outer wall of the extrusion block 16 approaches the conical inner wall of the shell 1, thereby performing preliminary extrusion and crushing of the koji blocks. When the lifting rod of the lifting mechanism 4 descends, the koji blocks that have been preliminarily crushed are further crushed. The yeast block falls through the gap between the extrusion block 16 and the surrounding plate 17 onto the sieve plate 3. The sieve plate 3 blocks the yeast block. Then, the lifting rod of the lifting mechanism 4 descends, causing the pressure plate 2 8 to descend. The pressure plate 2 8, through the spring 9, causes the pressure plate 1 5 and multiple pins 6 to descend synchronously, so that multiple protruding ends 7, along with multiple steel plates 11 on their outer sides, pass through the yeast block. The lower ends of the multiple pins 6 are blocked by the sieve plate 3. The lifting rod of the lifting mechanism 4 continues to descend the pressure plate 2 8, causing the spring 9 to be stretched. The pressure plate 2 8 drives multiple sleeves 10 and multiple steel plates 11 to continue to descend. The lower wedge-shaped platform of 1 intersects with the upper surfaces of the multiple protruding ends 7, causing the multiple steel plates 11 to open outwards from the multiple protruding ends 7 respectively. This allows the multiple steel plates 11 to break the yeast blocks from the inside out. Then, the lifting rod of the lifting mechanism 4 rises, causing the multiple needles 6 to disengage from the sieve plate 3. The elastic force of the spring 9 pulls the pressure plate 5 downwards, causing the multiple steel plates 11 to descend relative to the multiple needles 6. The elastic force of the multiple spring plates 12 keeps the lower ends of the multiple steel plates 11 pressed tightly against the outer walls of the multiple protruding ends 7. The multiple needles 6 repeatedly pierce the yeast blocks, thereby breaking the yeast blocks. The yeast blocks are crushed and finally pulverized to a suitable size and discharged into the receiving hopper 23 through multiple sieve holes of the sieve plate 3. When the lifting rod of the lifting mechanism 4 rises, the lifting rod pulls the lower end of the pusher plate 24 towards the inside and upward of the receiving hopper 23 through the pusher rod 25, so that the output port of the receiving hopper 23 opens. When the lifting rod of the lifting mechanism 4 falls, the lifting rod pushes the lower end of the pusher plate 24 towards the inside and downward of the receiving hopper 23 through the pusher rod 25, so that the pusher plate 24 pushes the yeast block fragments in the receiving hopper 23 out of the output port of the receiving hopper 23.

[0037] The main functions achieved by this invention are:

[0038] 1. The yeast blocks are repeatedly pierced and crushed, eliminating the need for further grinding. The crushing structure is simpler and more practical.

[0039] 2. It does not cut the yeast blocks, which reduces the breakage of fibers in the yeast blocks;

[0040] 3. The tips of multiple pins 6 pass through multiple sieve holes of the sieve plate 3 to avoid sieve hole clogging;

[0041] 4. It can perform two-stage pulverization of yeast blocks, with good pulverization effect;

[0042] 5. Crush the yeast blocks from the inside out to improve the crushing effect.

[0043] The brewing koji crushing device of the present invention has common mechanical installation, connection or setting methods, and can be implemented as long as it can achieve its beneficial effect. The housing 1, feeding hopper 2, sieve plate 3, lifting mechanism 4, pin 6, spring 9, steel plate 11, spring plate 12, nut 13, circular sieve plate 19 and receiving hopper 23 of the brewing koji crushing device of the present invention are purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
