Description

Technical Field

[0001] The utility model relates to the technical field of beer brewing, in particular to a malt beer brewing saccharification device with extrusion recovery function. Background Art

[0002] Filtration of wort after saccharification is a crucial process in beer production. Currently, breweries often use filtration equipment with screens or plates for separation. However, this traditional filtration equipment has several limitations when handling filter residue. For example, residual liquid within the residue is difficult to fully recover, resulting in resource waste. Furthermore, cleaning the residue requires downtime, which is time-consuming and inefficient.

[0003] A Chinese patent with authorization publication number CN219239599U discloses a "filtration mechanism for a beer suspension tank", which scrapes impurities from the surface of the filter residue with a brush, but does not involve the recovery of the liquid inside the filter residue; another patent with authorization publication number CN215742084U discloses a "beer saccharification tank filtration device", which increases the filtration speed by applying pressure through a piston plate, but its function is limited to accelerating the liquid flow rate, and the residual liquid in the filter residue is still difficult to effectively extract.

[0004] In addition, the above technical solution has the following shortcomings: the filter residue cleaning relies on the passive operation of the brush or scraper, which easily causes the filter residue to stick to the inner wall of the equipment and the cleaning is not thorough; at the same time, the filter residue is mostly discharged directly through the sewage pipe valve, and centralized collection cannot be achieved, which increases the difficulty of subsequent treatment. Utility Model Content

[0005] The purpose of the utility model is to provide a malt beer brewing saccharification device with extrusion recovery, aiming to solve the problems in the prior art of beer saccharification filtering devices that when processing filter residues, the liquid inside the filter residue is difficult to fully recover, the cleaning process is cumbersome, and the filter residue collection is inconvenient.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: the malt beer brewing and saccharification device with extrusion recovery includes a heating tank, a filtering mechanism, a lifting mechanism and a collecting mechanism. The right side of the heating tank is fixedly connected to a mounting plate, the left side of the mounting plate is fixedly connected to a connecting pipe, one end of the connecting pipe is connected to the heating tank; the filtering mechanism is arranged on the right side of the mounting plate, and includes a filter box, an inclined plate and a filter screen; the right end of the filter box is fixedly connected to a feed pipe, and the lower end is fixedly connected to two sets of oppositely arranged baffles, and a pull-out opening is formed between the two sets of baffles; the other end of the connecting pipe passes through the mounting plate and is fixed between the two sets of baffles; the inclined plate is fixedly connected to the filter screen, and the filter screen is horizontally arranged inside the pull-out opening and is located at the connecting plate. Above the tube, one end of the inclined plate close to the draw-out port is fixed to the filter screen, and the other end is inclined downward away from the draw-out port to form a flow channel connected to the connecting pipe; the inclined plate and the filter screen can be horizontally slidably arranged in the draw-out port; the lifting mechanism is installed at the upper end of the filter box, including a pressure plate; the pressure plate is slidably connected to the inside of the filter box, and the pressure plate vertically squeezes the filter residue on the filter screen at a pressure of 0.2-0.5MPa; the collecting mechanism is installed at the lower end of the baffle, including a horizontally slidable collecting box for receiving the filter residue scraped off the inner wall of the filter box.

[0007] In order to enable the present invention to efficiently recover the liquid inside the filter residue, the filtering mechanism also includes two sets of electric push rods; the electric push rods are respectively fixedly installed on the outside of the two sets of baffles, and their output ends are fixedly connected to a fixed plate. The end of the fixed plate away from the electric push rods is fixedly connected to the right end of the inclined plate, which is used to drive the inclined plate and the filter screen to slide horizontally along the drawer opening. When the electric push rods are extended or retracted, the fixed plate drives the inclined plate and the filter screen to move horizontally along the drawer opening, thereby peeling the filter residue from the filter screen and pushing it to the side of the inner wall of the filter box. At this time, the pressure plate of the lifting mechanism descends, applying vertical pressure to the filter residue, causing the residual liquid inside the filter residue to be squeezed out and refluxed through the flow channel to the connecting pipe, and finally flow into the heating tank for reuse.

[0008] A further technical solution of the utility model is that the lifting mechanism includes a fixed frame, a lifting plate, and a lifting screw; the fixed frame is fixedly connected to the upper end of the filter box, and the lifting plate is slidably connected inside; the lower end of the lifting plate is fixedly connected to two sets of lifting rods, the lower ends of which extend into the interior of the filter box and are fixedly connected to the pressure plate; the lifting screw is rotatably connected to the inner side of the fixed frame, and the lifting plate is threadedly connected to the outer side of the lifting screw; a servo motor is fixedly installed at the upper end of the fixed frame, and the output end of the servo motor is fixedly connected to the lifting screw, which is used to drive the lifting plate and the pressure plate to move vertically. When the servo motor is started, the lifting screw rotates, driving the lifting plate to move up and down along the inner side of the fixed frame, so that the pressure plate applies pressure or releases pressure on the filter residue.

[0009] To limit the movement of the lifting plate, the fixed frame is provided with a guide slot inside. Guide blocks are fixedly connected to both ends of the lifting plate, and the guide blocks are slidably connected to the guide slot. The coordinated design of the guide slot and the guide block ensures that the lifting plate can only move in the vertical direction, preventing the pressure plate from applying uneven pressure to the filter residue due to deviation.

[0010] To facilitate the collection of filter residue, the collection mechanism includes two sets of guide rails, each fixedly connected to the outside of the two sets of baffles. Two sets of guide rods are fixedly connected to the outside of the collection box, each of which is slidably connected to the inside of the guide rails. A handle is fixedly connected to the right side of the collection box for manually pulling the collection box. When the filter residue is pushed to the inner wall of the filter box by the inclined plate and filter screen, it falls into the collection box. Pulling the handle causes the collection box to slide horizontally along the guide rails, thereby centrally collecting and transferring the filter residue.

[0011] A further technical solution of the utility model is that the heating tank is rotatably connected to a rotating shaft, and a plurality of stirring rods are fixedly connected to the outside of the rotating shaft; a drive motor is fixedly mounted on the upper end of the heating tank, and the output end of the drive motor is fixedly connected to the rotating shaft; and a discharge valve is fixedly connected to the lower end of the outer side of the heating tank. The drive motor drives the rotating shaft to rotate, and the stirring rods stir the wort in the heating tank to promote the uniformity of the saccharification reaction. After saccharification is completed, the discharge valve is opened to discharge the wort into a filtering mechanism for separation.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The utility model drives the inclined plate and the filter screen to move horizontally through an electric push rod, peels the filter residue from the filter screen and pushes it to the side of the inner wall of the filter box. At the same time, the pressure plate of the lifting mechanism applies vertical pressure to the filter residue, so that the residual liquid inside the filter residue is squeezed out and flows back to the connecting pipe through the flow channel, and finally flows into the heating tank for reuse, solving the problem that the liquid inside the filter residue is difficult to fully recover.

[0014] 2. The utility model simplifies the filter residue cleaning process through the horizontal sliding design of the inclined plate and the filter screen, combined with the vertical extrusion function of the lifting mechanism, avoids frequent shutdown operations, and improves the working efficiency of the equipment.

[0015] 3. The utility model adopts the design of the collection mechanism, so that the filter residue is collected in a collection box, which is convenient for subsequent processing and solves the problem of inconvenient discharge of the filter residue.

[0016] 4. By controlling the extrusion pressure of the pressing plate (0.2-0.5 MPa), this utility model effectively squeezes out residual liquid from the filter residue, significantly reducing resource waste and avoiding inadequate liquid discharge due to insufficient pressure, or structural damage and contamination of the filter residue due to excessive pressure. The 0.2-0.5 MPa pressure range covers the extrusion requirements of different types of filter residue commonly used in beer brewing, such as malt and hops. For example, for malt residue, which is relatively soft, efficient liquid recovery is achieved at 0.2-0.3 MPa; for hop residue, which is relatively hard, sufficient liquid extrusion is achieved at 0.4-0.5 MPa, avoiding the problems of "overpressure damage" or "underpressure residue" caused by a single pressure, thereby improving the equipment's adaptability to different raw materials. Compared to equipment without pressure control, this utility model avoids unnecessary high-pressure energy consumption by limiting the pressure range and reduces the subsequent processing costs associated with excessive filter residue extrusion.

[0031] Example 1

[0032] Please refer to Figure 1- Figure 7 The utility model provides a malt beer brewing and saccharification device with extrusion recovery, comprising a heating tank 1 and a filtering mechanism 2 connected to the heating tank 1. A mounting plate 106 is fixedly installed on the right side of the heating tank 1. The left side of the mounting plate 106 is fixedly connected to one end of the connecting pipe 102. The other end of the connecting pipe 102 passes through the mounting plate 106 and extends into the interior of the filtering mechanism 2. The filtering mechanism 2 is arranged on the right side of the mounting plate 106, and comprises a filter box 201, an inclined plate 206, a filter screen 205 and a feed pipe 202. The feed pipe 202 is fixedly installed on the right end of the filter box 201, and two sets of oppositely arranged baffles 207 are fixed on the lower end, with a pull-out opening formed between the two sets of baffles 207. The connecting pipe 102 passes through the mounting plate 106 and is fixed between the two sets of baffles 207, communicating with the filter box 201. The inclined plate 206 is fixedly connected to the filter screen 205, which is horizontally arranged inside the drawer opening and above the connecting pipe 102. The inclined plate 206 is fixed to the filter screen 205 at one end near the drawer opening, and the other end is tilted downward away from the drawer opening to form a flow channel and communicate with the connecting pipe 102. The inclined plate 206 and the filter screen 205 can slide horizontally along the drawer opening.

[0033] The lifting mechanism 4 is located at the top of the filter box 201 and comprises a pressing plate 401, a fixing bracket 402, a lifting plate 403, and a lifting screw 404. The fixing bracket 402 is fixedly mounted on the top of the filter box 201 and is internally slidably connected to the lifting plate 403. Two sets of lifting rods 405 are fixed to the lower end of the lifting plate 403. The lower ends of the lifting rods 405 extend into the interior of the filter box 201 and are fixedly connected to the pressing plate 401. The pressing plate 401 vertically squeezes the filter residue from the filter screen 205 at a pressure of 0.2-0.5 MPa. Experimental results show that when the pressing plate 401 vertically squeezes the filter residue at a pressure of 0.2-0.5 MPa, the liquid recovery rate is significantly improved compared to conventional equipment.

[0034] The inner side of the fixed frame 402 is rotatably connected to the lifting screw 404, and the lifting plate 403 is connected to the outer side of the lifting screw 404 through a thread. A servo motor 406 is fixedly installed on the upper end of the fixed frame 402, and the output end of the servo motor 406 is fixedly connected to the lifting screw 404. A guide groove 408 is provided on the inner side of the fixed frame 402, and guide blocks 407 are fixedly connected at both ends of the lifting plate 403. The guide blocks 407 are slidably connected to the guide groove 408 to limit the lifting plate 403 to move only in the vertical direction. The collection mechanism 3 is arranged at the lower end of the baffle 207, and includes a collection box 303, a guide rail 301 and a guide rod 302. The guide rails 301 are respectively fixedly connected to the outer sides of the two sets of baffles 207, and the outer side of the collection box 303 is fixedly connected to the two sets of guide rods 302, and the guide rods 302 are respectively slidably connected to the inside of the guide rails 301. A handle 304 is fixedly installed on the right side of the collection box 303 to facilitate manual pulling of the collection box 303.

[0035] A rotating shaft 104 rotates inside the heating tank 1, and several stirring rods 105 are fixed to the outside of the rotating shaft 104. A drive motor 101 is fixedly mounted at the top of the heating tank 1, with the output end of the drive motor 101 fixedly connected to the rotating shaft 104. A discharge valve 103 is fixedly mounted at the lower end of the heating tank 1. When the drive motor 101 is turned on, it rotates the rotating shaft 104, and the stirring rods 105 stir the wort in the heating tank 1, promoting uniform saccharification. After saccharification is complete, the discharge valve 103 opens to discharge the wort into the filtration mechanism 2.

[0036] When the filter mechanism 2 is in operation, wort enters the filter box 201 from the feed pipe 202. After being filtered by the filter screen 205, the liquid flows back to the connecting pipe 102 through the flow channel formed by the inclined plate 206, and finally flows into the heating tank 1 for reuse. The electric push rod 203 is fixedly mounted on the outside of the two sets of baffles 207. The output end of the electric push rod 203 is fixedly connected to the fixed plate 204. The end of the fixed plate 204 away from the electric push rod 203 is fixedly connected to the right end of the inclined plate 206. Specifically, the electric push rod 203 pushes the fixed plate 204 at a speed of 10-15 cm / s, causing the inclined plate 206 to slide horizontally (stroke ≥ 80% of the filter screen width), ensuring a filter residue removal rate of >95%. When the electric push rod 203 is extended or retracted, the fixed plate 204 drives the inclined plate 206 and the filter screen 205 to move horizontally along the drawer opening, stripping the filter residue from the filter screen 205 and pushing it to the inner wall of the filter box 201.

[0037] When the lifting mechanism 4 is in operation, the servo motor 406 is activated, and the lifting screw 404 rotates, driving the lifting plate 403 up and down along the inside of the fixed frame 402. The lifting plate 403, via the lifting rod 405, drives the pressing plate 401 to move vertically. As the pressing plate 401 descends, it applies pressure to the filter residue, squeezing out any residual liquid within the residue and allowing it to flow back through the flow channel to the connecting pipe 102. The guide groove 408 and guide block 407 cooperate to ensure that the lifting plate 403 can only move vertically, preventing deviation that would cause the pressing plate 401 to apply uneven pressure to the filter residue.

[0038] When the collecting mechanism 3 is working, the filter residue is pushed to one side of the inner wall of the filter box 201 by the inclined plate 206 and the filter screen 205 and falls into the collecting box 303. By pulling the handle 304, the collecting box 303 slides horizontally along the guide rail 301 to achieve centralized collection and transfer of the filter residue.

[0039] The inclined plate 206 is fixedly connected to the filter screen 205. The inclined plate 206 is tilted to form a flow channel, and the liquid flows to the connecting pipe 102 through the inclined plate 206. When the inclined plate 206 and the filter screen 205 slide horizontally along the drawing port, the filter residue is peeled off from the filter screen 205 and pushed to one side of the inner wall of the filter box 201.

[0040] Guide grooves 408 are defined within the fixed frame 402. Guide blocks 407 are fixedly connected at both ends of the lifting plate 403. These guide blocks 407 are slidably connected to the guide grooves 408, restricting the lifting plate 403 to vertical movement. This design ensures that the lifting plate 403 remains stable during movement, preventing uneven pressure from the pressing plate 401 on the filter residue due to deviation.

[0041] When the entire device is in operation, malt and water are first added to the heating tank 1, the drive motor 101 is started to drive the rotating shaft 104 to rotate, and the stirring rod 105 stirs the wort in the heating tank 1 to promote the uniformity of the saccharification reaction. After saccharification is completed, the discharge valve 103 is opened to discharge the wort to the filtering mechanism 2. The wort enters the filter box 201 from the feed pipe 202, and after being filtered by the filter screen 205, the liquid flows back to the connecting pipe 102 through the flow channel formed by the inclined plate 206, and finally flows into the heating tank 1 for reuse. The electric push rod 203 is extended and retracted to drive the inclined plate 206 and the filter screen 205 to move horizontally along the pull-out port, peeling off the filter residue from the filter screen 205 and pushing it to the side of the inner wall of the filter box 201. Servo motor 406 activates, rotating lifting screw 404. Lifting plate 403 moves up and down along the inside of mounting bracket 402. Lifting rod 405 drives pressing plate 401 to move vertically, applying pressure to the filter residue, squeezing out any remaining liquid within the residue and allowing it to flow back through the flow channel to connecting pipe 102. The residue is pushed to the inner wall of filter box 201 and falls into collection box 303. Handle 304 is pulled to slide collection box 303 horizontally along guide rail 301, enabling centralized collection and transfer of the residue.

[0042] In order to better enable relevant personnel in this technical field to fully understand and implement the present invention, the operating principle and implementation steps of the present invention are supplemented below in combination with specific application scenarios.

[0043] In practice, the operator first adds malt and water in the correct proportions to the heating tank 1. The drive motor 101 is activated, rotating the shaft 104. The stirring rod 105 on the shaft 104 then stirs the mixed liquid in the heating tank 1 to promote uniform saccharification. After saccharification is complete, the discharge valve 103 is opened, and the mixed liquid flows through the connecting pipe 102 into the filter box 201 of the filtration mechanism 2. During this process, the liquid passes through the filter screen 205, completing solid-liquid separation. The filtrate then flows back to the connecting pipe 102 along the channel formed by the inclined plate 206, ultimately returning to the heating tank 1 for reuse.

[0044] After the filtration is completed, the electric push rod 203 is started, and the electric push rod 203 pushes the fixed plate 204 at a speed of 14 cm / s to drive the inclined plate 206 to slide horizontally. Its output end pushes the fixed plate 204, and the fixed plate 204 drives the inclined plate 206 and the filter screen 205 to move horizontally along the pull-out opening. The sliding design of the inclined plate 206 and the filter screen 205 allows the filter residue to be peeled off from the surface of the filter screen 205 and pushed to one side of the inner wall of the filter box 201. This process effectively prevents the filter residue from sticking to the filter screen 205, thereby improving the cleaning efficiency. At the same time, since the inclined plate 206 is tilted and connected to the connecting pipe 102, the filtrate can smoothly flow back to the heating tank 1 under the action of gravity, thereby reducing liquid residue.

[0045] Subsequently, the servo motor 406 is started, driving the lifting screw 404 to rotate, and the lifting screw 404 pushes the lifting plate 403 to move vertically along the inner side of the fixed frame 402 through threaded transmission. The lifting plate 403 drives the pressure plate 401 to descend through the lifting rod 405, exerting pressure on the filter residue. The pressure plate 401 vertically squeezes the filter residue on the filter screen 205 at a pressure of 0.2 MPa. The pressure of the pressure plate 401 causes the residual liquid inside the filter residue to be squeezed out. The squeezed liquid flows back to the connecting pipe 102 along the flow channel formed by the inclined plate 206, and finally flows into the heating tank 1. The cooperation between the guide groove 408 and the guide block 407 ensures that the lifting plate 403 can only move in the vertical direction, avoiding the problem of uneven pressure caused by offset, thereby ensuring the efficiency and effect of extrusion recovery.

[0046] Once the filter residue is fully squeezed, the inclined plate 206 and filter screen 205 move horizontally again along the drawer opening, pushing the residue further toward the inner wall of the filter box 201 and into the collection box 303. The collection box 303 slides horizontally thanks to the cooperation of the guide rails 301 and the guide rods 302. The operator can pull the handle 304 to remove the collection box 303, once filled with filter residue, for centralized processing. This design not only simplifies the filter residue cleaning process but also facilitates its subsequent centralized recovery and utilization.

[0047] Throughout the entire process, the coordinated operation of the inclined plate sliding to peel off the filter residue, the pressure plate vertically squeezing and recovering the liquid, and the collection tank for centralized collection achieves effective recovery of residual liquid from the filter residue, automatic cleaning of the filter residue, and centralized collection. For example, the tilt angle and flow path design of the inclined plate 206 ensure efficient liquid reflux; the telescopic movement of the electric push rod 203 and the rotation of the servo motor 406 cooperate to achieve the separation and extrusion of the filter residue and the recovery of the filter residue, respectively; and the design of the guide rail 301 and guide rod 302 facilitates the centralized collection of the filter residue.

[0048] Through the above steps, the utility model not only solves the problem that it is difficult to fully recover the liquid inside the filter residue in traditional filtering equipment, but also significantly improves the efficiency of filter residue cleaning and realizes the centralized collection of filter residue, providing a more efficient and convenient solution for the saccharification and filtration link in the beer brewing process.

[0057] Comparative Example 2

[0058] Different from Example 1, the pressing plate 401 vertically squeezes the filter residue on the filter screen 205 at a pressure of 0.6 MPa.

[0059] According to the above embodiment, the following experiments were performed:

[0060] 1. Experimental conditions:

[0061] The sample was malt residue after saccharification from a brewery (initial mass 100 g, initial moisture content 75±2%, sampled after uniform mixing); the experimental equipment used was the device of the utility model (Examples 1-4) and the device of the utility model (pressure adjusted, Comparative Example 1 and Comparative Example 2); the experimental environment temperature was 25±2°C, and the humidity was 50±5%.

[0062] 2. Experimental steps:

[0063] 1. Sample pretreatment: Take 100g of filter residue sample, weigh and record the initial mass (m0=100g) and initial moisture content (ω0=75%);

[0064] 2. Equipment operation:

[0065] Example 1-4: The servo motor 406 is started to control the pressing plate 401 to squeeze the filter residue at pressures of 0.2 MPa, 0.3 MPa, 0.4 MPa, and 0.5 MPa for 5 minutes;

[0066] Comparative Example 1-2: The parameters of the servo motor 406 were adjusted so that the pressing plate 401 squeezed the filter residue at pressures of 0.1 MPa and 0.6 MPa for 5 minutes;

[0067] 3. Data collection:

[0068] Collect the squeezed liquid and weigh it (m1);

[0069] Weigh the mass of the filter residue after extrusion (m2), m2 includes the residual liquid and solid dry weight, and measure its residual moisture content (ω), and calculate the residual moisture content: ω=[(m2- m 干 ) / m2]×100%, where m 干 = m0×(1-ω0) (m0 is the total mass of the initial filter residue, ω0 is the initial moisture content);

[0071] The experimental results are shown in Table 1:

[0072] Table 1 Liquid recovery index and residue moisture content data after extrusion of the device under different platen pressures

[0073]

[0074] Experimental conclusion:

[0075] 1. The liquid recovery rates of Examples 1-4 were 82%-85%, significantly higher than those of Comparative Example 1 (55%) and Comparative Example 2 (65%), demonstrating that 0.2-0.5 MPa is the optimal pressure range for liquid recovery.

[0076] 2. In Comparative Example 1 (0.1 MPa), the pressure was too low, resulting in a liquid recovery rate of only 55% and a residual moisture content of 45%. This indicates that insufficient pressure could not fully squeeze out the liquid inside the filter residue. In Comparative Example 2 (0.6 MPa), the pressure was too high. Although the liquid recovery rate increased to 65%, the residual moisture content of the filter residue was still higher than that of the embodiment (35% vs. 25%). In addition, the high pressure increased the energy consumption of the servo motor by approximately 30% (not reflected in the table), resulting in reduced economic efficiency.
