Abstract

The present invention discloses an anti-adhesion malt crushing device for beer production and its production process, which relates to the field of beer production and includes a bottom plate and a crushing cylinder fixedly connected to the center of its top. A driving mechanism is installed on the top of the bottom plate. In the present invention, through the synergistic effect of the first rotating frame and the linkage rod, the synchronous movement of the two piston blocks is driven. When the linkage rod rotates, it not only drives the first rotating frame to do circular motion, but also transmits power through the linkage block, enabling the two piston blocks to move symmetrically and in opposite directions, ensuring the overall efficient and stable operation. In addition, through the two-way air flow design of the sleeve through the intake pipe and the charging pipe, the impact force of the air flow is significantly improved, thereby enhancing the overall working efficiency. This air flow design can also effectively provide dry cold air to ensure the reasonable control of the temperature and humidity inside the crushing cylinder. Through continuous air flow circulation, not only can heat be taken away, the humidity of the particles can be reduced, and particle adhesion can be avoided.

Description

Technical Field

[0001] The invention relates to the technical field of beer production, in particular to an anti-adhesion malt crushing device for beer production and a production process thereof. Background Art

[0002] Malt crushing is a critical step in beer production before saccharification. Its purpose is to improve the contact between starch and enzymes within the malt, thereby improving saccharification efficiency and facilitating smoother filtration. The degree of malt crushing directly affects saccharification efficiency, wort clarity, and the taste and flavor of the final beer.

[0003] For example, the publication number CN119237106A, "A raw material crushing mechanism and method for craft beer processing and production", includes a circular ring seat with a horizontal axis, a shaft seat fixedly connected to the top of the inner wall of the circular ring seat, a first shaft rotatably connected to the shaft seat, the axis of the first shaft coincides with the axis of the circular ring seat, crushing knives evenly distributed around the circumference are fixedly connected to the first shaft, and a transmission mechanism for driving the first shaft to rotate is fixedly connected to the circular ring seat.

[0004] However, in the prior art, during the malt crushing process, malt contains a large amount of starch, which is a hydrophilic substance. In an environment with high humidity, starch molecules will absorb surrounding moisture and swell. The swollen starch granules become softer and are easy to contact and adhere to each other. Malt granules are also easy to adhere to the crushing mechanism, which in turn causes equipment blockage and affects the uniformity of the crushing effect. This adhesion phenomenon not only reduces the crushing efficiency, but also easily leads to unstable equipment operation and increased maintenance costs. In addition, the unevenness of malt crushing will affect the controllability of the saccharification process, such as affecting the enzymatic hydrolysis efficiency of starch, resulting in uneven sugar content distribution of the saccharification liquid, thereby affecting the quality of the final wort. Especially under high humidity or poor raw material storage conditions, the hygroscopicity of the malt is enhanced, and it is more likely to clump or adhere to the surface of the equipment, which aggravates the processing difficulty.

[0017] A production process for preventing adhesion of malt during beer production includes the following steps:

[0018] S1. The driving mechanism is started, and the malt to be crushed is poured into the inside of the crushing cylinder. The first driving motor drives the first driving bevel gear to rotate, driving the first driven bevel gear to rotate, making the second rotating frame rotate, and then driving the large gear, small gear, and driving wheel to rotate, transmitting power through the synchronous belt, and driving the driven wheel to rotate synchronously;

[0019] S2. The air inflation mechanism is started. The driven wheel drives the first rotating frame to rotate. At the same time, the linkage rod and the linkage block move synchronously, pushing the first piston rod and the internal piston block to move, making the two piston blocks move in opposite directions, and introducing dry cold air;

[0020] S3. Driven by the worm and worm gear mechanism, the second driving motor drives the worm to rotate, and the worm drives the worm gear to rotate, making the rotating disk, the first movable rod, the transmission rod, and the movable block move, and driving the second movable rod to make a reciprocating motion under the restriction of the fixed block, realizing the linkage of the crushing mechanism;

[0021] S4. The driving sleeve drives the crushing rod. The second driving bevel gear drives the second driven bevel gear to rotate, making the driving sleeve drive the second movable rod to reciprocate up and down and rotate through the convex block and the groove. At the same time, the movable plate is driven to rotate, and finally transmitted to the crushing rod.

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

[0023] 1. In the present invention, through the synergistic effect of the first rotating frame and the linkage rod, the synchronous movement of the two piston blocks is driven. When the linkage rod rotates, it not only drives the first rotating frame to perform a circular motion, but also transmits power through the linkage block, enabling the two piston blocks to move symmetrically and in opposite directions, ensuring the overall efficient and stable operation. In addition, through the two-way air flow design of the sleeve via the intake pipe and the charging pipe, the impact force of the air flow is significantly increased, thereby improving the overall working efficiency. This air flow design can also effectively provide dry cold air to ensure reasonable control of the temperature and humidity inside the crushing cylinder. Through continuous air flow circulation, not only can heat be removed, the particle humidity be reduced, and particle adhesion be avoided;

[0024] 2. In the present invention, the first driving motor drives the first driven bevel gear through the first driving bevel gear, and then drives the second rotating frame to rotate, ensuring the synchronous operation of the large gear and the small gear. The rotation of the small gear causes the driving wheel to start working, and power is transmitted through the synchronous belt. During this process, the guide wheel effectively guides the synchronous belt, avoiding deviation and power loss, thus ensuring the stability of the transmission mechanism. Finally, the synchronous rotation of the driven wheel drives the rotation of the first rotating frame, driving each transmission component to work in coordination, ensuring the smooth start-up and normal operation of the inflation mechanism;

[0025] 3. In the present invention, the second driving motor drives the worm to rotate, driving the movement of the worm gear and the rotating disk, and then enabling the first movable rod, the transmission rod, the movable block, and the second movable rod to move in coordination, realizing the compound movement of reciprocating up and down and rotating. The driving sleeve further enhances the crushing effect of the second movable rod through the convex block and the groove. At the same time, the dual movement of the movable plate and the crushing rod provides multi-angle efficient crushing. The inflation mechanism continuously provides dry cold air, effectively reducing material adhesion and lowering the equipment temperature, ensuring long-term stable operation. The overall coordinated movement and anti-adhesion design not only improve the crushing quality but also optimize the equipment performance, ensuring the efficient processing of high-humidity or easily adherent materials and significantly enhancing the working efficiency.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1: Refer to Figure 1 - Figure 7 As shown in the figure: An anti-adhesion malt crushing device for beer production includes a bottom plate 1 and a crushing cylinder 2 fixedly connected to the center of its top. A driving mechanism 4 is installed on the top of the bottom plate 1. Four inflation mechanisms 3 are evenly distributed on the peripheral side of the crushing cylinder 2. The driving mechanism 4 is in transmission connection with the inflation mechanisms 3. A crushing mechanism 6 is installed inside the crushing cylinder 2, and the crushing mechanism 6 is used for crushing malt.

[0039] The inflation mechanism 3 includes a fixed frame 31 and a sleeve 32 fixedly arranged on one side thereof. Two piston blocks 34 are symmetrically and slidably connected in the inner cavity of the sleeve 32. A second piston rod 391 is fixedly connected to the inner side of one of the piston blocks 34, and a first piston rod 36 is rotatably connected to the inner side of the other piston block 34. Both sides of the bottom end of the first piston rod 36 are rotatably connected to a linkage block 38. One end of the linkage block 38 is fixedly connected to a first rotating frame 37. The top end of the second piston rod 391 is fixedly connected to a limit frame 39. Both ends of the limit frame 39 are rotatably connected to a linkage rod 35. The bottom end of the linkage rod 35 is rotatably connected to the middle of the first rotating frame 37. The top side wall of the fixed frame 31 is fixedly connected to a limit block 311. A limit rod 33 is slidably connected inside the limit block 311. The bottom end of the limit rod 33 is fixedly connected to the center of the top of the limit frame 39.

[0040] One side of the middle of the sleeve 32 is fixedly communicated with an air inlet pipe 321, and the other side of the middle of the sleeve 32 is fixedly communicated with an inflation pipe 322. Check valves are installed inside both the air inlet pipe 321 and the inflation pipe 322. One end of the air inlet pipe 321 penetrates through the fixed frame 31, and one end of the inflation pipe 322 penetrates through the crushing cylinder 2. The first rotating frame 37 is rotatably connected to the inner wall of the fixed frame 31, and the bottom of the fixed frame 31 is fixedly connected to the top of the bottom plate 1.

[0041] In this embodiment, during the process of the first rotating frame 37 starting to rotate, the linkage block 38 is driven to perform a corresponding circular motion. This continuous transmission process causes the first piston rod 36 to move accordingly and push one of the piston blocks 34 inside the sleeve 32 to perform a reciprocating motion. During this process, due to the coordinated work of the first rotating frame 37 and the linkage rod 35, the linkage rod 35 will further drive the movement of the limit frame 39 during its movement, so that the second piston rod 391 drives the other piston block 34 to perform a corresponding movement along with the movement of the limit frame 39.

[0042] However, due to different connection methods, the two piston blocks 34 move in opposite directions during the movement process, enabling a symmetric and efficient mode during operation. In addition, air intake and exhaust are respectively carried out through the intake pipe 321 and the charging pipe 322 from the sleeve 32, and the air intake direction is from the intake pipe 321 to the charging pipe 322. During this process, the air flow rate entering the crushing cylinder 2 is doubled, which not only enhances the impact force of the air flow, improves the overall working efficiency, but also provides sufficient dry cold air during the malt crushing process to ensure that the temperature and humidity inside the crushing cylinder 2 are controlled within a reasonable range. Through continuous air flow circulation, not only can heat be effectively removed, but also the humidity of the particles can be reduced, preventing particle adhesion caused by excessive humidity, thereby improving the crushing quality and the controllability of subsequent processes; multiple small-diameter charging pipes 322 are adopted as a whole, so that the cold air is evenly dispersed into the interior of the crushing cylinder 2, avoiding the formation of a concentrated strong air flow. This can reduce the disturbance to the starch powder while lowering the environmental temperature and humidity.

[0043] Meanwhile, during the movement of the limit frame 39, the limit rod 33 will be driven to move synchronously. The movement of the limit rod 33 is restricted by the limit block 311, so that it always maintains a linear movement, avoiding deviation or swing, thereby ensuring that the entire mechanism can still maintain good stability and accuracy during multiple reciprocating movements.

[0044] Embodiment 2: Figure 1 - Figure 3 As shown, the driving mechanism 4 includes a second rotating frame 45. The second rotating frame 45 is rotatably connected to the bottom plate 1, and the shaft end of the second rotating frame 45 penetrates through the bottom plate 1. A first driven bevel gear 44 is fixedly connected to the outer surface of the shaft end of the second rotating frame 45. A large gear 42 is fixedly connected to the outside of the second rotating frame 45. A first driving bevel gear 43 is meshed and connected to one side of the first driven bevel gear 44. A first driving motor 41 is fixedly connected to the bottom of the bottom plate 1. The output end of the first driving motor 41 is fixedly connected to the first driving bevel gear 43. A small gear 46 is meshed and connected to the outside of the large gear 42. A driving wheel 461 is fixedly connected to the shaft end of the small gear 46. A support frame 47 is fixedly connected to the top of the bottom plate 1. One end of the support frame 47 is fixedly connected to a rotating rod 472. Guide wheels 471 are rotatably connected to the outer surfaces of both ends of the rotating rod 472. One end of one of the first rotating frames 37 is fixedly connected to a driven wheel 48. A synchronous belt 49 is sleeved on the outer surface of the driven wheel 48. The synchronous belt 49 is attached to the inner side of the guide wheel 471, and one end of the synchronous belt 49 is sleeved on the outer surface of the driving wheel 461.

[0045] In this embodiment, the first drive motor 41 can drive the first driving bevel gear 43 to start rotating. The first driving bevel gear 43 will exert a meshing force on the first driven bevel gear 44, causing the second rotating frame 45 to start rotating. During the rotation of the second rotating frame 45, the large gear 42 mounted thereon will rotate accordingly, and apply a driving force to the small gear 46 through meshing, causing the small gear 46 to start synchronous rotation. The rotation of the small gear 46 will be further transmitted to the driving wheel 461 mounted on its top, causing the driving wheel 461 to start operating, and power is transmitted through the synchronous belt 49 on the outer surface.

[0046] During this process, the guide wheel 471 on the outer surface of the rotating rod 472 plays a guiding and restricting role to ensure that the synchronous belt 49 can operate stably, while avoiding deviation or power loss. With the transmission of power, the driven wheel 48 will also achieve synchronous rotation, and the rotation of the driven wheel 48 further drives the first rotating frame 37 to rotate. During the rotation of the first rotating frame 37, it will drive the linkage rod 35 and the linkage block 38 to operate in coordination, thereby ensuring that the overall inflation mechanism 3 can be smoothly started and enter the normal working state.

[0047] Embodiment 3: According to Figure 8 - Figure 10As shown in the figure, the crushing mechanism 6 includes a rotating disk 61. A first movable rod 62 is rotatably connected to the side wall of the rotating disk 61. The top end of the first movable rod 62 is rotatably connected to a transmission rod 63. One end of the transmission rod 63 is fixedly connected to a movable block 66. The bottom end of the movable block 66 is rotatably connected to a second movable rod 661. A worm gear 612 is fixedly connected to one side of the rotating disk 61, and a second driving bevel gear 611 is fixedly connected to the side wall of the rotating disk 61. The outer surface of the middle part of the second movable rod 661 is slidably connected to a fixed block 65. The side wall of the fixed block 65 is rotatably connected to the rotating disk 61. The bottom end of the fixed block 65 is rotatably connected to a driving sleeve 67. A convex block 673 is fixedly connected to the inner wall of the driving sleeve 67. A groove 674 is formed on the outer surface of the second movable rod 661, and the second movable rod 661 is slidably connected to the driving sleeve 67. The groove 674 is slidably connected to the convex block 673. A second driven bevel gear 671 is fixedly connected to the outer surface of the driving sleeve 67. The second driven bevel gear 671 is meshed and connected to the second driving bevel gear 611. A movable plate 672 is fixedly connected to the outer surface of the driving sleeve 67. One end of the bottom of the movable plate 672 is rotatably connected to a crushing rod 69. A transmission gear 681 is fixedly connected to the outer surface of the top end of the crushing rod 69. A toothed ring 68 is fixedly connected to the inner wall of the crushing cylinder 2. The toothed ring 68 is meshed and connected to the transmission gear 681. Crushing knives 7 are fixedly connected to the outer surfaces of the bottom ends of the crushing rod 69 and the second movable rod 661. An installation frame 51 is fixedly connected to the top of the crushing cylinder 2. A second driving motor 5 is installed on the top of the installation frame 51. The output end of the second driving motor 5 is fixedly connected to a worm 64. The worm 64 is meshed and connected to the worm gear 612. A sleeve 21 is fixedly connected to the center of the inner cavity of the crushing cylinder 2. A filter bag 22 is fixedly connected to the middle of the sleeve 21. It is made of woven filter cloth or non-woven felt. The fiber fabric filtering effect enables gas to enter and can bear the tension of the internal contents. A discharge pipe is fixedly communicated with the center of the bottom end of the filter bag 22.

[0048] In this embodiment, under the driving action of the second driving motor 5, the worm 64 starts to rotate and applies a force to the worm gear 612 during the rotation process. As the worm gear 612 rotates, the rotating disk 61 rotates accordingly. During this process, the rotating disk 61 drives the first movable rod 62 to perform corresponding movements, and the movement of the first movable rod 62 further drives the transmission rod 63 to start moving. When the rotating disk 61 continues to rotate, the movable block 66 not only moves along with the transmission rod 63 and performs a linear reciprocating motion, but also further drives the second movable rod 661 to move. Under the restricting action of the fixed block 65, the second movable rod 661 starts to perform a linear reciprocating motion. In addition, when the second driving bevel gear 611 rotates, it also applies a force to the second driven bevel gear 671, causing the second driven bevel gear 671 to drive the driving sleeve 67 to rotate. During the rotation of the driving sleeve 67, the convex block 673 and the groove 674 on it apply a force to the second movable rod 661, enabling the second movable rod 661 to not only perform up and down reciprocating motions but also perform rotational motions, enhancing its crushing effect.

[0049] As the drive sleeve 67 rotates the movable plate 672, the breaker bar 69, connected to the bottom of the movable plate 672, also performs a circular motion about the drive sleeve 67. During this process, the transmission gear 681 is acted upon by the gear ring 68, causing the gear ring 68 to rotate the breaker bar 69. Consequently, the breaker bar 69 not only rotates on its own but also moves within the inner sleeve 21. Simultaneously, the dual reciprocating and rotating motion of the drive sleeve 67 enables the breaker bar 69 to efficiently and effectively crush materials from multiple angles, enhancing the overall crushing effect.

[0050] To further optimize the crushing process and prevent material adhesion, an air charging mechanism 3 is also included. This mechanism continuously injects dry, cool air into the crushing area, improving crushing efficiency while effectively reducing material adhesion. Furthermore, the introduction of dry, cool air lowers the internal temperature of the equipment, reducing the adverse effects of frictional heat on the crushing process and ensuring long-term stable operation. The coordinated movement of the entire crushing mechanism 6, combined with efficient crushing methods and anti-adhesion measures, enables the equipment to perform better when handling high-humidity or easily sticky materials, significantly improving crushing quality and operating efficiency.

[0051] The present invention provides a production process for anti-adhesion malt crushing in beer production as follows:

[0052] S1. Pour the malt to be crushed into the crushing drum 2. The first drive motor 41 rotates the first driving bevel gear 43. The meshing force of the first driving bevel gear 43 drives the first driven bevel gear 44, which in turn causes the second turret 45 to rotate. The second turret 45 rotates the large gear 42, which in turn acts on the small gear 46, causing it to rotate and, in turn, the top driving wheel 461. The driving wheel 461 transmits power via the synchronous belt 49 on its outer surface. During this process, the guide wheel 471 on the outer surface of the rotating rod 472 acts as a guide and limiter, causing the driven wheel 48 to rotate synchronously.

[0053] During S2 rotation, the driven wheel 48 drives the first turret 37 to rotate, thereby activating the overall aeration mechanism 3. When the first turret 37 begins to rotate, it drives the linkage block 38 to move synchronously. At this point, the first piston rod 36 begins to move, driving one of the piston blocks 34 inside the sleeve 32. As the first turret 37 drives the linkage rod 35 to move, the linkage rod 35 drives the limit frame 39 to move, which in turn drives the second piston rod 391 and the other piston block 34 to move synchronously. Because the two piston blocks 34 move in opposite directions, and the air intake pipe 321 and the aeration pipe 322 are located in the middle of the sleeve 32, the two piston blocks 34 effectively increase the airflow rate. During the malt crushing process, they help introduce dry, cool air, remove heat, reduce grain humidity, and prevent sticking caused by excessive humidity.

[0054] S3. The second drive motor 5 drives the worm 64 to rotate. The worm 64 applies a force to the worm gear 612, causing the worm gear 612 to rotate, and then driving the rotating disk 61 to rotate. The rotating disk 61 drives the first movable rod 62 to move, and then drives the transmission rod 63 to move. The movable block 66 moves accordingly, and at the same time drives the second movable rod 661 to move. The second movable rod 661 makes a linear reciprocating motion under the restriction of the fixed block 65.

[0055] S4. The second driving bevel gear 611 applies a force to the second driven bevel gear 671, causing the second driven bevel gear 671 to drive the drive sleeve 67 to rotate. The drive sleeve 67 uses the convex block 673 and the groove 674 to apply a force, so that the second movable rod 661 also starts to rotate when moving up and down reciprocally.

[0056] The drive sleeve 67 drives the movable plate 672 to rotate, and then makes the crushing rod 69 perform a circular motion. The transmission gear 681 is affected by the toothed ring 68 and drives the crushing rod 69 to rotate. The crushing rod 69 not only rotates itself, but also moves within the inner sleeve 21. Combining the up-and-down reciprocating and rotational movements of the drive sleeve 67 significantly improves the crushing effect. The dry cold air provided by the air inflation mechanism 3 can avoid material adhesion while enhancing the crushing effect.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
