Description

Technical Field

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

[0002] In beer production, malt milling is a key pretreatment step, designed to moderately break down the malt grains to fully expose the internal starch granules while keeping the husks relatively intact. Traditional mills (mainly roller mills) use multiple sets of relatively rotating rollers to crush the malt.

[0003] Most malt grinding equipment lacks the necessary screening and impurity removal steps, resulting in the crushing of malt straw and leaves along with the malt, affecting the drinking taste of the beer. On the other hand, most equipment inevitably leaves some malt particles uncrushed during the grinding process, leading to uneven malt particle size and affecting the final quality of the beer. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a malt crusher for beer production, which can prevent wheat straw or wheat leaves from being mixed into the malt and affecting the taste of the product through the screening component, and improve the product quality by secondary crushing of unqualified malt particles through the transmission component.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] A malt grinder for beer production includes: a workbench, a grinding box mounted on the top of the workbench, a connecting plate connected to the bottom of the workbench, a receiving box located at the bottom of the workbench, a bulk material frame connected to the top of the grinding box, a feeding cylinder connected to the top of the bulk material frame, a screening component disposed inside the bulk material frame for screening residual straw or leaves in the malt particles, the screening component including: a sprocket a, an auger a, and a filter screen, and a transmission component disposed at the bottom of the workbench for transmitting incompletely ground malt particles to the bulk material frame, the transmission component including: a screening plate, a triangular guide plate, and an auger b.

[0007] Preferably, two motors a are installed on one side of the crushing box, and each of the two motors a is driven by a rotating rod a. One end of the rotating rod a extends into the interior of the crushing box and is connected to a crushing roller. A sprocket a is connected to the outer side of one of the rotating rods a. A sprocket b is provided on one side of the crushing box, and a chain is provided between the sprocket b and the sprocket a. A rotating rod b is connected to one side of the sprocket b, and one end of the rotating rod b extends into the interior of the bulk material frame and is connected to an auger a. A transmission groove for use with the auger a is opened inside the bulk material frame. A filter screen is connected to the bottom of the transmission groove, and the bottom of the filter screen communicates with the top of the crushing box. A miscellaneous material box is installed on one side of the crushing box, and a discharge port is opened at the top of the miscellaneous material box. The top of the discharge port communicates with the bottom of the transmission groove.

[0008] Preferably, the bottom of the crushing box has a discharge port, and a screening plate is provided at the bottom of the discharge port. A mounting plate is connected to one side of the connecting plate, and a buffer groove a is provided inside the mounting plate. A connecting block a is connected to one side of the screening plate, and one end of the connecting block a extends into the buffer groove a. A spring a is provided on one side of the connecting block a. A recycling frame is installed on the top of the workbench, and one end of the recycling frame penetrates the workbench and protrudes from the lower surface of the workbench. An opening is provided on one side of the recycling frame, and a triangular guide plate is connected to one side of the opening. A buffer groove b is provided inside the triangular guide plate. A fixed plate is connected inside the b, and a spring b is connected to one side of the fixed plate. A connecting block b is set inside the buffer groove b. The top of the connecting block b is connected to the bottom of the screening plate. An electric push rod is connected to one side of the connecting plate. A fixed block is set on one side of the electric push rod. One end of the electric push rod corresponds to one side of the fixed block. The top of the fixed block is connected to the bottom of the screening plate. A motor b is installed on the top of the recycling frame. An auger b is set inside the recycling frame. The bottom of the motor b is driven by one end of the auger b through a drive shaft. A secondary crushing pipe is connected between the recycling frame and the bulk material frame.

[0009] The beneficial effects of this utility model are:

[0010] The advantage of this invention is that by utilizing the sprocket a, auger a, and filter screen in the screening assembly, the rotation of auger a can prevent malt particles entering from the feed cylinder from clogging the filter screen. Through the filtering effect of the filter screen and the pushing of the spiral blades of auger a, the straw and leaves in the malt particles are effectively filtered out and transported to the inside of the miscellaneous material box by the spiral blades, preventing straw or leaves from being mixed into the malt and affecting the taste of the product.

[0011] Secondly, through the screening plate, triangular guide plate, and auger B in the transmission assembly, the electric push rod continuously impacts the screening plate back and forth, causing the screening plate to screen malt particles that meet the size requirements. The back-and-forth movement of the screening plate causes malt particles that are not properly ground to pass through the triangular guide plate into the recycling frame, where they are then transported to the top of the recycling frame by the auger B. From there, they enter the heat dissipation frame through the secondary grinding pipe for secondary grinding of the unqualified malt particles, thus improving product quality.

Detailed Implementation

[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0020] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-6 As shown, a malt grinder for beer production includes a workbench 1, a grinding box 101 mounted on top of the workbench 1, a connecting plate 102 connected to the bottom of the workbench 1, a receiving box 103 located at the bottom of the workbench 1, a bulk material frame 104 connected to the top of the grinding box 101, a feeding cylinder 105 connected to the top of the bulk material frame 104, a screening component located inside the bulk material frame 104 for screening residual straw or leaves in the malt particles, the screening component including: a sprocket a202, an auger a401 and a filter screen 402, and a transmission component located at the bottom of the workbench 1 for transmitting incompletely ground malt particles to the bulk material frame 104, the transmission component including: a screening plate 5, a triangular guide plate 602 and an auger b703.

[0022] The sprocket a202, auger a401, and filter screen 402 in the screening assembly prevent malt particles entering from the feed cylinder 105 from clogging at the filter screen 402 through the rotation of the auger a401. The filtration effect of the filter screen 402, combined with the pushing action of the auger a401's spiral blades, effectively filters out wheat straw and leaves from the malt particles, which are then conveyed to the waste bin 403 by the spiral blades, preventing wheat straw or leaves from mixing into the malt and affecting the product's taste. Furthermore, the transmission assembly... The sieve plate 5, triangular guide plate 602, and auger b703 in the sieve are connected by an electric push rod 7 that continuously impacts the sieve plate 5. This causes the sieve plate 5 to sieve malt particles that meet the size requirements. The forward and backward movement of the sieve plate 5 causes malt particles that are not properly ground to pass through the triangular guide plate 602 into the recycling frame 6. There, they are transported to the top of the recycling frame 6 by the auger b703 and then enter the bulk material frame 104 through the secondary crushing pipe 704. The unqualified malt particles are then subjected to secondary crushing to improve product quality.

[0023] Two motors a2 are installed on one side of the crushing box 101. Each motor a2 drives a rotating rod a201 on one side. One end of the rotating rod a201 extends into the crushing box 101 and is connected to a crushing roller 203. A sprocket a202 is connected to the outside of one of the rotating rods a201. A sprocket b3 is provided on one side of the crushing box 101. A chain 302 is provided between the sprocket b3 and the sprocket a202. A rotating rod b301 is connected to one side of the sprocket b3. One end of the rotating rod b301 extends into the bulk material frame 104 and is connected to an auger a401. A transmission groove 4 for use with the auger a401 is opened inside the bulk material frame 104. A filter screen 402 is connected to the bottom of the transmission groove 4. The bottom of the filter screen 402 communicates with the top of the crushing box 101. A waste material box 403 is installed on one side of the crushing box 101. A discharge port 404 is opened at the top of the waste material box 403. The top of the discharge port 404 communicates with the bottom of the transmission groove 4.

[0024] Most equipment, lacking the necessary screening and impurity removal steps during malt grinding, inadvertently crushes malt straw and leaves along with the malt, affecting the beer's taste. In this equipment, when motor a2 drives the rotating rod a201 and grinding roller 203 to rotate, the rotation of rod a201 drives sprocket a202, which in turn drives sprocket b3 via chain 302, causing rotating rod b301 to rotate. Rotating rod b301 then drives the auger a401 located in the transmission groove 4 inside the bulk material frame 104 to rotate. The malt mixture entering from the feed cylinder 105 first falls onto the filter screen 402 in the transmission groove 4, and the rotating auger a401... The rotating motion of the spiral blades continuously agitates and pushes the malt mixture falling onto the filter screen 402, preventing it from accumulating and clogging the filter screen surface. On the other hand, the pushing motion of the spiral blades causes the malt particles to move, thus passing through the mesh of the filter screen 402 and falling into the crushing box 101 below for crushing. At the same time, larger impurities such as straw and leaves cannot pass through the mesh of the filter screen 402 and are continuously pushed by the spiral blades of the rotating auger 401, moving along the transmission groove 4. Finally, they are forcibly pushed out into the waste bin 403 for collection through the outlet at the bottom of the transmission groove 4, which is connected to the discharge port 404 at the top of the waste bin 403. This effectively separates impurities and prevents them from being mixed into the crushing process and affecting the taste of the beer.

[0025] The crushing box 101 has a discharge port 505 at its bottom, and a screening plate 5 is installed at the bottom of the discharge port 505. A mounting plate 504 is connected to one side of the connecting plate 102, and a buffer groove a501 is provided inside the mounting plate 504. A connecting block a502 is connected to one side of the screening plate 5, with one end of the connecting block a502 extending into the buffer groove a501. A spring a503 is provided on one side of the connecting block a502. A recycling frame 6 is installed on the top of the workbench 1, with one end of the recycling frame 6 penetrating the workbench 1 and protruding from its lower surface. An opening 601 is provided on one side of the recycling frame 6, and a triangular guide plate 602 is connected to one side of the opening 601. A buffer groove b603 is provided inside the triangular guide plate 602. A fixing plate 604 is connected internally to the 03. A spring b605 is connected to one side of the fixing plate 604. A connecting block b606 is set inside the buffer groove b603. The top of the connecting block b606 is connected to the bottom of the screening plate 5. An electric push rod 7 is connected to one side of the connecting plate 102. A fixing block 701 is set on one side of the electric push rod 7. One end of the electric push rod 7 corresponds to one side of the fixing block 701. The top of the fixing block 701 is connected to the bottom of the screening plate 5. A motor b702 is installed on the top of the recycling frame 6. An auger b703 is set inside the recycling frame 6. The bottom of the motor b702 is driven by one end of the auger b703 through a drive shaft. A secondary crushing pipe 704 is connected between the recycling frame 6 and the bulk material frame 104.

[0026] In most equipment, some malt particles inevitably remain uncrushed during pulverization, resulting in uneven malt particle size and affecting the final quality of the beer. In this equipment, the pulverized malt mixture is discharged from the outlet 505 at the bottom of the pulverizing chamber 101 and falls onto the screening plate 5. The electric push rod 7, by striking the fixed block 701, causes the screening plate 5 to reciprocate back and forth along the buffer groove a501 on the mounting plate 504. As the screening plate 5 moves, the connecting block a502 on one side slides within the buffer groove a501 and compresses the spring a503 to provide cushioning. The connecting block b606 on the other side moves within the buffer groove b603 along with the screening plate 5. When the screening plate 5 moves, the spring b605 provides cushioning for the connecting block b606. During the reciprocating back and forth movement of the screening plate 5, malt particles reaching the specified particle size pass through the mesh of the screening plate 5 and fall into the lower part of the chamber. In the receiving box 103, larger, unqualified malt particles remain on the surface of the screening plate 5. As the screening plate 5 moves back and forth, these unqualified particles gradually slide down onto the triangular guide plate 602 under the influence of gravity. The particles slide down the inclined surface of the triangular guide plate 602 and enter the opening on one side of the recycling frame 6. At this time, the auger b703 in the recycling frame 6 is driven to rotate by the motor b702. The spiral blades of the rotating auger b703 lift and convey the unqualified malt particles that have fallen to the bottom of the recycling frame 6 upwards. The particles that have been lifted to the top of the recycling frame 6 flow back into the conduction groove 4 area inside the bulk material frame 104 through the secondary crushing pipe 704 connected between the top of the recycling frame 6 and the bulk material frame 104. These returned unqualified particles will then pass through the filter screen 402 of the screening component again and fall into the crushing box 101 to undergo secondary crushing together with new raw materials, thereby ensuring the crushing quality of the final product.

[0027] Working principle:

[0028] Most equipment, lacking the necessary screening and impurity removal steps during malt grinding, inadvertently crushes malt straw and leaves along with the malt, affecting the beer's taste. In this equipment, when motor a2 drives the rotating rod a201 and grinding roller 203 to rotate, the rotation of rod a201 drives sprocket a202, which in turn drives sprocket b3 via chain 302, causing rotating rod b301 to rotate. Rotating rod b301 then drives the auger a401 located in the transmission groove 4 inside the bulk material frame 104 to rotate. The malt mixture entering from the feed cylinder 105 first falls onto the filter screen 402 in the transmission groove 4, and the rotating auger a401... The rotating motion of the spiral blades continuously agitates and pushes the malt mixture falling onto the filter screen 402, preventing it from accumulating and clogging the filter screen surface. On the other hand, the pushing motion of the spiral blades causes the malt particles to move, thus passing through the mesh of the filter screen 402 and falling into the crushing box 101 below for crushing. At the same time, larger impurities such as straw and leaves cannot pass through the mesh of the filter screen 402 and are continuously pushed by the spiral blades of the rotating auger 401, moving along the transmission groove 4. Finally, they are forcibly pushed out into the waste bin 403 for collection through the outlet at the bottom of the transmission groove 4, which is connected to the discharge port 404 at the top of the waste bin 403. This effectively separates impurities and prevents them from being mixed into the crushing process and affecting the taste of the beer.

[0029] In most equipment, some malt particles inevitably remain uncrushed during pulverization, resulting in uneven malt particle size and affecting the final quality of the beer. In this equipment, the pulverized malt mixture is discharged from the outlet 505 at the bottom of the pulverizing chamber 101 and falls onto the screening plate 5. The electric push rod 7, by striking the fixed block 701, causes the screening plate 5 to reciprocate back and forth along the buffer groove a501 on the mounting plate 504. As the screening plate 5 moves, the connecting block a502 on one side slides within the buffer groove a501 and compresses the spring a503 to provide cushioning. The connecting block b606 on the other side moves within the buffer groove b603 along with the screening plate 5. When the screening plate 5 moves, the spring b605 provides cushioning for the connecting block b606. During the reciprocating back and forth movement of the screening plate 5, malt particles reaching the specified particle size pass through the mesh of the screening plate 5 and fall into the lower part of the chamber. In the receiving box 103, larger, unqualified malt particles remain on the surface of the screening plate 5. As the screening plate 5 moves back and forth, these unqualified particles gradually slide down onto the triangular guide plate 602 under the influence of gravity. The particles slide down the inclined surface of the triangular guide plate 602 and enter the opening on one side of the recycling frame 6. At this time, the auger b703 in the recycling frame 6 is driven to rotate by the motor b702. The spiral blades of the rotating auger b703 lift and convey the unqualified malt particles that have fallen to the bottom of the recycling frame 6 upwards. The particles that have been lifted to the top of the recycling frame 6 flow back into the conduction groove 4 area inside the bulk material frame 104 through the secondary crushing pipe 704 connected between the top of the recycling frame 6 and the bulk material frame 104. These returned unqualified particles will then pass through the filter screen 402 of the screening component again and fall into the crushing box 101 to undergo secondary crushing together with new raw materials, thereby ensuring the crushing quality of the final product.

The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail in the article.
