Description

Technical Field

[0001] This utility model relates to the field of beer production technology, specifically to a malt crushing device. Background Technology

[0002] Beer originated in Mesopotamia during the Neolithic period, around 10,000 BC. People in what is now Kurdistan accidentally discovered the enzymes necessary for converting grain starch into fermentable sugars when grains sprouted due to dampness, thus beginning the path of beer brewing. Malt is the main ingredient in beer, providing the sugars and proteins needed for fermentation. Its quality directly affects the taste and flavor of beer. Barley malt is usually used, but wheat malt and other types of malt may be used depending on the type of beer.

[0003] In beer brewing, malt needs to be pulverized. Existing technology, such as the malt pulverizing device disclosed in patent announcement number CN211160081U, includes a pulverizing chamber with a turntable inside. A rotating chamber shell is fixedly connected to the top of the turntable, and a first fixing block is sleeved on the outside of the rotating chamber shell. The first fixing block is elastically connected to the inner wall of the pulverizing chamber via a first tension spring. A second fixing block is welded to the inner wall of the pulverizing chamber. In this invention, a drive motor is located on the side of the pulverizing chamber opposite to the push rod. The output shaft of the drive motor is driven by a main gear disk. A fixing sleeve is sleeved on the output shaft of the drive motor, and the fixing sleeve is fixedly connected to the pulverizing chamber via a fixing rod. The outer side of the main gear disk is engaged with a gear belt via teeth, and the inner side of the gear belt is engaged with a secondary gear disk via teeth.

[0004] This technology has the advantage that when in use, only one drive motor can control the switching of the crushing device, the multi-chamber crushing, and the rotation of the crushing blades. It not only consumes little power but also saves a lot of costs. However, it requires the malt to be dehulled beforehand, and then crushed, which requires two processes. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a malt crushing device, which can effectively solve the problem that the existing technology requires pre-hulling of malt, followed by crushing, which requires two processes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a malt crushing device, including a base, a water tank fixed on the base, a feed box fixedly connected to the upper end of the water tank, two hulling rollers symmetrically and rotatably installed inside the feed box, levers evenly fixed on the sides of the hulling rollers, the levers on the sides of the two hulling rollers being staggered, a groove being opened through the inner side of the feed box, the levers being able to pass through the groove as the hulling rollers rotate, an opening being opened on the upper surface of the water tank, a conveyor belt being inclinedly installed in the opening, a crushing box being fixed on the base, the end of the conveyor belt being located directly above the opening on the crushing box, and two cooperating crushing rollers being rotatably installed inside the crushing box.

[0008] According to the malt crushing device described above, the hulling roller extends out of the inner side of the feed box and is fixed with a hulling pulley. The two hulling pulleys are connected by a hulling power transmission belt. One of the hulling pulleys is fixedly connected to a hulling motor, which is fixed on the outer side of the feed box.

[0009] According to the malt crushing device described above, a pulley is rotatably mounted on the outer side of the water tank. The shaft of the pulley inside the water tank extends laterally to the other inner side of the water tank, and push plates are fixed in a circular array on the side of the shaft. A conveying motor is fixed at the end of the pulley extending out of the water tank, and the conveying motor is fixedly mounted on the base.

[0010] According to the above-mentioned malt crushing device, a conveyor pulley is rotatably installed on the outer side of the water tank. The actuating pulley and the conveyor pulley are connected by a conveyor belt. A conveyor roller is rotatably installed above the crushing box. A conveyor belt is driven by the outer side of the conveyor pulley and the conveyor roller. Multiple baffles are evenly arrayed on the outer surface of the conveyor belt.

[0011] According to the malt crushing device described above, two meshing gears are rotatably mounted on the outer side of the crushing roller. One of the gears is coaxially fixed with a power transmission pulley. The power transmission pulley is connected to the drive pulley via a crushing power belt.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0014] This invention utilizes a motor to drive a hulling pulley, which in turn drives another hulling pulley via a hulling transmission belt. This, in turn, drives two hulling rollers. The rotation of these rollers causes a lever to rotate, which in turn moves the malt to hull it. The malt and its hulls then fall into a water tank filled with water. The malt hulls float on the surface while the malt sinks. The malt is then conveyed by a conveyor belt and baffles to the opening at the top of a crushing chamber. As the malt falls, it is guided into the crushing chamber by an inclined plate. The crushing rollers then crush the falling malt, combining the hulling and crushing processes into one, saving significant manpower and resources. Attached Figure Description

[0023] The hulling motor 21 drives the hulling pulley 22 to rotate, which in turn drives another hulling pulley 22 to rotate via the hulling transmission belt 23. This, in turn, drives two hulling rollers 24 to rotate. The rotation of the two hulling rollers 24 drives the lever 25 to rotate along with the hulling rollers 24. The lever 25 then moves the malt to hull it. The malt and its husks then fall into the water tank 3, which is filled with water. The malt husks float on the water surface, while the malt sinks into the water, completing the hulling process. Afterward, the malt is conveyed to the upper opening of the crushing box 4 via the conveyor belt 37 and the baffle 38. The malt falls into the crushing box 4 and is guided by the inclined plate 41. The crushing roller 44 rotates to crush the falling malt. This process combines the hulling and crushing processes into one, saving a lot of manpower and resources.

[0024] The shelling roller 24 extends out of the inner side of the feed box 2 and is fixed with a shelling pulley 22. The two shelling pulleys 22 are connected by a shelling transmission belt 23. One of the shelling pulleys 22 is fixedly connected to a shelling motor 21. The shelling motor 21 is fixed on the outer side of the feed box 2. When the shelling motor 21 operates, it drives the shelling pulley 22 to rotate, which in turn drives the other shelling pulley 22 to rotate through the shelling transmission belt 23.

[0025] A rotating pulley 32 is mounted through the outer side of the water tank 3. A push plate 321 is fixed in a circular array on the side of the pulley 32 inside the water tank 3. A conveyor motor 31 is fixed at the end of the pulley 32 extending out of the water tank 3. The conveyor motor 31 is fixedly mounted on the base 1. When the conveyor motor 31 operates, it drives the pulley 32 to rotate. As the pulley 32 rotates, the push plate 321 can move the malt at the bottom of the water tank 3 to the side with the conveyor belt 37.

[0026] A crushing power belt 35 is rotatably mounted through the outer side of the water tank 3. A conveyor pulley 33 is fixed to the end of the crushing power belt 35 extending out of the water tank 3. The actuating pulley 32 and the conveyor pulley 33 are connected by a conveyor belt 34. A conveyor roller 36 is rotatably mounted on the top of the crushing box 4. A conveyor belt 37 is mounted on the outer side of the crushing power belt 35 and the conveyor roller 36. Multiple baffles 38 are arrayed on the outer surface of the conveyor belt 37. The rotation of the actuating pulley 32 also drives the conveyor pulley 33 to rotate through the conveyor belt 34. The rotation of the conveyor pulley 33 drives the conveyor belt 37 and the conveyor roller 36 to move, realizing the conveying function. The malt is conveyed to the upper opening position of the crushing box 4 through the cooperation of the conveyor belt 37 and the baffles 38.

[0027] Two meshing gears 43 are rotatably mounted on the outer side of the crushing roller 44. One of the gears 43 is coaxially fixed with a force transmission pulley 42. The force transmission pulley 42 is connected to the drive pulley 32 via the crushing power belt 35. The two gears 43 are coaxially fixed with the corresponding crushing rollers 44. The malt falls and enters the crushing box 4 through the guidance of the inclined plate 41. The rotation of the drive pulley 32 also drives the force transmission pulley 42 to rotate through the crushing power belt 35. The rotation of the force transmission pulley 42 drives the meshing gears 43 to rotate, which in turn drives the two cooperating crushing rollers 44 to rotate. The rotation of the crushing rollers 44 crushes the falling malt.

[0028] The lower surface of the crushing box 4 is provided with a discharge hole, and a discharge baffle 45 is fixed at the discharge hole. The finished product box 5 is placed directly below the discharge baffle 45. The crushed malt falls into the finished product box 5 through the discharge baffle 45, thus completing the crushing operation.

[0029] The working principle of this utility model is as follows: Malt is put into the feed box 2, and the hulling motor 21 is started. The hulling motor 21 drives the hulling pulley 22 to rotate, which in turn drives another hulling pulley 22 to rotate through the hulling transmission belt 23. This, in turn, drives two hulling rollers 24 to rotate. The rotation of the two hulling rollers 24 drives the lever 25 to rotate with the hulling rollers 24. The lever 25 then pushes the malt to hull it. Subsequently, the malt and its husks fall into the water tank 3. The water tank 3 is filled with water, so the malt husks float on the water surface. The conveyor motor 31 is started, and the conveyor motor 31 drives the lever 32 to rotate. The push plate 321, along with the lever 32, pushes the malt at the bottom of the water tank 3 to the conveyor belt 37.

The rotation of the conveyor pulley 33 drives the conveyor belt 37 and the conveyor roller 36 to move, realizing the conveying function. The malt is conveyed to the upper opening position of the crushing box 4 through the cooperation of the conveyor belt 37 and the baffle 38. The malt falls and enters the crushing box 4 through the guidance of the inclined plate 41. The rotation of the actuating pulley 32 also drives the transmission pulley 42 to rotate via the crushing power belt 35. The rotation of the transmission pulley 42 drives the meshing gear 43 to rotate, which in turn drives the two cooperating crushing rollers 44 to rotate. The rotation of the crushing rollers 44 crushes the falling malt. The crushed malt falls into the finished product box 5 through the discharge baffle 45, completing the crushing operation.
