Description

Technical Field

[0001] This invention relates to the field of beer production technology, and in particular to a filter device and process for beer production with a self-cleaning filter plate. Background Technology

[0002] Beer production is a fermented beverage made from barley, water, hops, and yeast as core raw materials, through core processes such as malting, saccharification, fermentation, filtration, and bottling. The core process involves using the enzyme system of malt to convert starch into fermentable sugars, and then using the anaerobic respiration of yeast to convert the sugars into alcohol and carbon dioxide, while producing various flavor compounds. The filtration equipment in beer production includes two types: wort filtration (after saccharification) and beer filtration (after fermentation).

[0003] Chinese Patent Publication No. CN216584935U discloses a filtration device with a self-cleaning filter plate for beer production, belonging to the field of beer production technology. The device includes a housing with a drain outlet at the bottom and a feed inlet at the top. A filter plate is fixed to the top of the housing, and both sides of the filter plate have sediment troughs. A reciprocating screw is mounted on the top of the filter plate, rotatably between the two sides of the housing. A slider is slidably mounted on the reciprocating screw. The design of the rotating rod and blades inside the flow channel allows control of the rotation of the connecting rod during the dripping of the filtered liquid. Combined with a transmission mechanism consisting of a rotating chamber, a driving wheel, a driven wheel, and a belt, this controls the rotation of the reciprocating screw, which in turn controls the scraper at the bottom of the slider to move back and forth on the top of the filter plate, performing self-cleaning of the filter plate. This ensures the filtration rate during device use and prevents clogging.

[0004] However, the above-mentioned device relies on the impact of the filter juice blades for power during operation. When the flow rate is insufficient, the scraper cannot operate normally. In contrast, this application utilizes the weight of the wheat bran and hot water to drive the cleaning mechanism, which does not rely on the flow rate of the filter juice. Even if the amount of filter juice is small, it can achieve the purpose of stable cleaning. Summary of the Invention

[0005] The main objective of this invention is to provide a filter device and process for beer production with a self-cleaning filter plate, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A self-cleaning filtration device with a filter plate for beer production includes a processing tank mounted on the ground, an inlet for feeding malt onto one side of the upper end of the processing tank, and a conical mixing cylinder for collecting wort on the lower side of the inner surface of the processing tank. A guide rail is fixedly installed on the lower side of the inner surface of the processing tank. A filter assembly for filtering malt is provided on one side of the inner surface of the processing tank. A tapping assembly for cleaning the filter assembly is provided above the filter assembly. A second guide cylinder is provided on the side of the inner surface of the processing tank away from the filter assembly. A rinsing assembly for rinsing malt is provided on the side of the filter assembly near the second guide cylinder. An auxiliary assembly is provided on the inner surface of the processing tank below the second guide cylinder. A malt washing assembly for assisting in malt washing and filtration is provided on the inner surface of the processing tank below the auxiliary assembly. A pushing assembly is provided on the inner surface of the processing tank.

[0007] Preferably, the filtration assembly includes a partition plate disposed on one side of the top wall of the inner surface of the processing tank. A filter plate one for filtering wort is disposed on the upper part of the partition plate near the feed inlet. A filter plate two is disposed in the middle of one end of the partition plate below the filter plate one. A filter plate three is disposed at one end of the partition plate below the filter plate two. The wort to be filtered is slowly fed into the inner surface of the processing tank from the feed inlet. The wort containing sugar is separated by the cooperation of the filter plates one, two, and three, leaving the wort. A guide tube one for guiding the wort is disposed on the inner surface of the processing tank below the filter plate three.

[0008] Preferably, the partition plate has three through holes at the end near the first filter plate, and the three through holes are respectively adapted to the first filter plate, the second filter plate, and the third filter plate. A control valve is provided on the inner surface of each of the three through holes. The partition plate has three guide pipes at the end away from the first filter plate, and the three guide pipes are adapted to the three through holes.

[0009] Preferably, the rinsing assembly includes a water pump disposed on one side of the upper end of the treatment tank, a water pipe disposed at the lower end of the water pump, and three arc-shaped spray plates fixedly connected to the end of the water pipe away from the water pump. The three arc-shaped spray plates are respectively fixedly connected to the top wall of the inner surface of the adapted guide pipe.

[0010] Preferably, the auxiliary component includes a second circular roller that is slidably mounted on the inner surface of the processing tank, a second telescopic rod that is provided on the outer surface of the second circular roller, a fixed seat that is fixedly connected to the end of the second circular roller away from the inner surface of the processing tank, a first circular roller that is fixedly connected to the end of the fixed seat away from the second circular roller, and a conical box that is movably mounted in the middle of the upper end of the fixed seat.

[0011] Preferably, the striking assembly includes six L-shaped rollers, which are rotatably mounted on one end of the partition near the filter plate. Arc-shaped springs are fixedly connected to the middle of the outer surface of each of the six L-shaped rollers and the partition.

[0012] Preferably, two telescopic rods are symmetrically fixedly installed on the lower side of the partition near the guide pipe. A crossbar is fixedly installed on the upper end of the two telescopic rods. The middle part of the upper end of the crossbar is fixedly connected to the outer surface of the circular roller. Six thin ropes are symmetrically fixedly installed on the upper end of the crossbar. The six thin ropes are respectively fixedly connected to the outer surface of the adapted L-shaped roller.

[0013] Preferably, the pushing assembly includes an L-shaped roller two fixedly installed on the outer surface of the circular roller two, a vertical plate slidably connected to the outer surface of the guide rail, a vertical groove opened at one end of the vertical plate near the conical box, an inclined groove opened at one end of the vertical plate communicating with the lower side of the inner surface of the vertical groove, one side of the outer surface of the L-shaped roller two slidably connected to the inner surface of the vertical groove, and a bending roller fixedly connected to the upper side of the vertical plate.

[0014] Preferably, the washing slag assembly includes a fan-shaped box fixedly installed on one side of the inner surface of the processing tank, a conical guide tube fixedly connected to the lower end of the fan-shaped box, the lower end of the conical guide tube being located on the inner surface of the conical mixing cylinder, and a filter plate for filtering wheat slag being provided on the lower side of the inner surface of the fan-shaped box.

[0015] This invention also provides a beer filtration process, comprising the following steps: Step 1: Pretreatment. Close the valve of the device. After malt saccharification, add the Pyrrosia lingua extract and stir well. Prepare hot water at 75-78℃. Step 2: Filter, pour in the mixed mash, collect the first wort, and activate the self-cleaning function to remove residual malt. Step 3: Washing the lees, using constant-temperature hot water to wash the lees, filtering the lees liquid and mixing it with the first wort; Step 4: Finishing, output the mixed wort to the boiling process, clean and dry the equipment, and then add hops and yeast for fermentation.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention employs an inclined design with progressively smaller pore sizes in filter plates one, two, and three, along with guide blocks on the partitions. This allows the mash to fall from the feed inlet and undergo three stages of filtration to progressively intercept different particle sizes of wasps, ensuring the clarity of the first wort. A fan-shaped box collects the hot water mixed with wasps poured out of the conical box. After filtration by filter plate four, the wasps-washed wort flows through a conical guide tube into a conical mixing tube, where it is thoroughly mixed with the first wort. This ensures that the two wors are completely mixed before being output uniformly, avoiding uneven wort concentration caused by batch output. At the same time, filter plate four intercepts wasps after washing, preventing them from mixing into the mixed wort and affecting the quality.

[0017] 2. In this invention, after the hot water mixed with wheat lees falls into the conical box, its own weight increases, causing the fixed base, roller one, and roller two to descend. On one hand, roller one pulls the crossbar, causing the thin rope to pull L-shaped roller one to compress the arc spring; on the other hand, roller two drives L-shaped roller two to slide along the vertical plate groove, pushing the vertical plate and the bending roller to tilt the conical box to pour the material. After the material is poured, the components reset, and the arc spring rebounds, pushing L-shaped roller one to strike the filter plate. This not only shakes off the attached wheat lees and promotes their fall, but also achieves self-cleaning of the filter plate, avoiding clogging and affecting subsequent filtration efficiency. It also allows the wheat lees and hot water to be mixed quantitatively and slowly before entering the washing component, avoiding insufficient washing due to a large amount of material added at once, and improving the sugar extraction rate.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a filtration device with a self-cleaning filter plate for beer production includes a processing tank 1 installed on the ground, an inlet 11 for feeding malt onto one side of the upper end of the processing tank 1, and a conical mixing cylinder 13 for collecting wort on the lower side of the inner surface of the processing tank 1. A guide rail 12 is fixedly installed on the lower side of the inner surface of the processing tank 1. A filter assembly 3 for filtering malt is installed on one side of the inner surface of the processing tank 1. A tapping assembly 4 for cleaning the filter assembly 3 is installed above the filter assembly 3. A second guide cylinder 5 is installed on the side of the inner surface of the processing tank 1 away from the filter assembly 3. A rinsing assembly 2 for rinsing malt is installed on the side of the filter assembly 3 close to the second guide cylinder 5. An auxiliary assembly 6 is installed on the inner surface of the processing tank 1 below the second guide cylinder 5. A malt washing assembly 7 for assisting in malt washing and filtration is installed on the inner surface of the processing tank 1 below the auxiliary assembly 6. A pushing assembly 8 is installed on the inner surface of the processing tank 1.

[0022] After the malt ferments to form mash, the saccharified mash needs to be filtered. The mash to be filtered is added to the inner surface of the processing tank 1 through the feed inlet 11. After being filtered by the filter assembly 3, a clear "first wort" is obtained. Then, the rinsing assembly 2 is used to rinse the filtered slag, and the slag washing assembly 7 is used for filtration to wash out as much residual sugar as possible. All the wort is collected using the conical mixing cylinder 13.

[0023] Furthermore, a valve is provided on the lower side of the inner surface of the conical mixing cylinder 13. When filtering the mash and rinsing the lees, the valve on the lower side of the inner surface of the conical mixing cylinder 13 is closed to ensure that the "first wort" is mixed with the water used to rinse the lees before being output. After the lees are filtered, the valve is opened to output the mixed wort inside the conical mixing cylinder 13 in preparation for boiling the wort.

[0024] like Figure 4 The filter assembly 3 includes a partition 36 disposed on one side of the top wall of the inner surface of the processing tank 1. A filter plate 31 for filtering washer is disposed on the upper part of the partition 36 near the feed inlet 11. A filter plate 32 is disposed in the middle of one end of the partition 36 below the filter plate 31. A filter plate 33 is disposed at one end of the partition 36 below the filter plate 32. The washer to be filtered is slowly fed into the inner surface of the processing tank 1 from the feed inlet 11. The sugary wort is separated by the cooperation of the filter plate 31, the filter plate 32 and the filter plate 33, leaving the washer. A guide tube 34 for guiding the wort is disposed on the inner surface of the processing tank 1 below the filter plate 33.

[0025] It should be noted that the filter plate 31, filter plate 32, and filter plate 33 mentioned above are all inclined. Furthermore, the pore size of filter plate 31 is larger than that of filter plate 32 and also larger than that of filter plate 33. Figure 5 Furthermore, guide blocks are provided at the connection points between filter plate 31, filter plate 32, and filter plate 33 and partition plate 36, ensuring that the wheat residue remaining at the top of filter plate 31, filter plate 32, and filter plate 33 can flow towards the middle through the guidance of the guide blocks.

[0026] After the mash to be filtered enters the inner surface of the processing tank 1 through the feed inlet 11, it falls directly onto the upper end of the filter plate 31. The "first wort" inside the mash falls through the filter plate 31. At the same time, through the cooperation of the filter plate 31, filter plate 32, and filter plate 33, the different apertures ensure that all the malt in the mash is intercepted at the upper end of the filter plate 31, filter plate 32, and filter plate 33. After passing through the filter plate 31, filter plate 32, and filter plate 33, the "first wort" is collected on the inner surface of the guide tube 34 and then on the inner surface of the conical mixing tube 13.

[0027] like Figure 4 The partition 36 has three through holes at the end near the filter plate 31. The three through holes are respectively adapted to the filter plate 31, the filter plate 32, and the filter plate 33. A control valve 35 is provided on the inner surface of each of the three through holes. The partition 36 has three guide pipes 37 at the end away from the filter plate 31. The three guide pipes 37 are adapted to the three through holes.

[0028] Furthermore, after the mash is separated from the wort by the cooperation of filter plate 31, filter plate 32 and filter plate 33, the three control valves 35 are opened, and the mash slides along the upper end of filter plate 31, filter plate 32 and filter plate 33 towards the inner surface of the matching through hole.

[0029] like Figure 8 The rinsing assembly 2 includes a water pump 21 located on one side of the upper end of the treatment tank 1. A water pipe 22 is located at the lower end of the water pump 21. Three arc-shaped spray plates 23 are fixedly connected to the end of the water pipe 22 away from the water pump 21. The three arc-shaped spray plates 23 are respectively fixedly connected to the top wall of the inner surface of the adapted guide pipe 37.

[0030] It should be noted that the upper end of the aforementioned water pump 21 is connected to a constant temperature hot water source in the prior art, and the hot water temperature is the standard temperature for rinsing wheat bran, that is, the hot water temperature is between 75 and 78 degrees Celsius.

[0031] The lower arc surface of the three arc-shaped spray plates 23 mentioned above is equipped with several nozzles.

[0032] Furthermore, after the first filter plate 31, the second filter plate 32, and the third filter plate 33 have completed filtration, and after the three control valves 35 are opened, the water pump 21 starts running. The water pump 21 then delivers constant-temperature hot water to the three arc-shaped spray plates 23 through the water pipes 22, and sprays it out through several nozzles on the lower arc surface of the arc-shaped spray plates 23.

[0033] The wheat bran mixed with hot water flowing out through the through hole is guided out through the guide pipe 37, such as... Figure 9 And through the interception and guidance of the guide tube 25, the mixed hot water lees flow downward.

[0034] like Figure 10 The auxiliary component 6 includes a second round roller 64 that is slidably installed on the inner surface of the processing tank 1. A telescopic rod 65 is provided on the outer surface of the second round roller 64. A fixed seat 62 is fixedly connected to one end of the second round roller 64 away from the inner surface of the processing tank 1. A first round roller 63 is fixedly connected to one end of the fixed seat 62 away from the second round roller 64. A conical box 61 is movably installed in the middle of the upper end of the fixed seat 62.

[0035] The upper end of the aforementioned telescopic rod 265 is fixedly connected to the output end of a hydraulic drive rod commonly used in the prior art.

[0036] An elastic protective cover is provided at the connection between the outer surface of the roller 2 64 and the inner surface of the processing tank 1. During the up-and-down movement of the roller 2 64, the elastic protective cover is stretched and deformed. At the same time, the elastic protective cover prevents the volatile components in the lees, hot water or wort from affecting the connection between the roller 2 64 and the processing tank 1.

[0037] The lower side of the outer surface of the aforementioned conical box 61 is movably connected to the upper middle part of the fixed seat 62 via a universal ball, and an elastic roller is fixedly connected between the fixed seat 62 and the universal ball. A protective cover is provided on the outside of the elastic roller and the universal ball to ensure that the universal ball and other structures will not contaminate the wheat lees.

[0038] Furthermore, the downward-flowing hot water mixed with wheat lees falls into the inner surface of the conical box 61 and continuously accumulates on the inner surface of the conical box 61, which in turn causes the total weight of the conical box 61 and the internal mixture to slowly increase, thereby causing the conical box 61 to slowly descend. As the conical box 61 descends, it pushes the fixed seat 62, the first roller 63, and the second roller 64 to descend simultaneously. Through the guidance of the second guide tube 5, the hot water mixed with wheat lees flowing out along the guide tube 37 falls evenly inside the conical box 61 and does not splash in any direction. That is, the trajectory of the conical box 61 descending due to its own weight is vertical.

[0039] Similarly, if the three control valves 35 are opened, the wheat residue filtered from the upper ends of filter plate 31, filter plate 32 and filter plate 33 will not be able to actively pass through the matching through holes and control valves 35 and mix with hot water along the guide pipe 37 due to excessive friction between adjacent wheat residues, even under the influence of gravity. At this time, the hot water will enter the conical box 61 through the guide pipe 37 and the guide cylinder 2 5, which will also increase the weight of the conical box 61, causing the conical box 61 to drive the fixed seat 62, roller 1 63 and roller 2 64 to slowly descend.

[0040] At the same time, as the roller 264 is pushed down, the telescopic rod 265 is stretched.

[0041] like Figure 6 The striking assembly 4 includes six L-shaped rollers 41, which are rotatably mounted on one end of the partition 36 near the filter plate 31. Arc-shaped springs 43 are fixedly connected to the middle of the outer surface of each of the six L-shaped rollers 41 and the partition 36 respectively.

[0042] The outer surfaces of the six curved springs 43 are all provided with protective sleeves to ensure that the curved springs 43 do not contaminate the wort and lees.

[0043] Meanwhile, the aforementioned L-shaped roller 41 will not obstruct the falling mash or lees.

[0044] like Figure 7 Two telescopic rods 44 are symmetrically fixedly installed on the lower side of the partition plate 36 near the guide pipe 37. A crossbar 45 is fixedly installed on the upper end of the two telescopic rods 44. The middle part of the upper end of the crossbar 45 is fixedly connected to the outer surface of the circular roller 63. Six thin ropes 42 are symmetrically fixedly installed on the upper end of the crossbar 45. The six thin ropes 42 are respectively fixedly connected to the outer surface of the matching L-shaped roller 41.

[0045] Furthermore, during the filtration of the mash, the L-shaped roller 41 is affected by its own weight, causing the adapted arc spring 43 to be in a stretched state, while the adapted thin rope 42 is in a taut but unforced state.

[0046] The connection between the upper middle part of the crossbar 45 and the outer surface of the circular roller 63 can be provided by means of a slot fixation, which only needs to ensure that the upper part of the crossbar 45 is fixed to the circular roller 63 when filtering the mash, and that the crossbar 45 can be released from the circular roller 63 after the mash filtration is completed and the lees are rinsed.

[0047] Similarly, the lower ends of the two telescopic rods 44 are fixedly connected to the output end of the hydraulic drive rod in the prior art, and the outer surfaces of the two telescopic rods 44 and the hydraulic drive rod are protected to prevent the wheat bran and hot water from affecting the operation of the telescopic rods 44 or the hydraulic drive rod, and also to prevent the hydraulic drive rod or the telescopic rod 44 from producing impurities that affect the wheat bran.

[0048] As more and more hot water mixed with wheat lees is collected inside the conical box 61, the conical box 61 drives the fixed seat 62, the first roller 63, and the second roller 64 to descend. During the descent of the first roller 63, the crossbar 45 is pushed down, which at the same time squeezes the two telescopic rods 44.

[0049] During the descent of the crossbar 45, the lower ends of the six thin ropes 42 descend simultaneously. As the thin ropes 42 are pulled and subjected to force, they cause the adapted L-shaped roller 41 to rotate towards the side closer to the partition 36, while simultaneously squeezing the adapted arc spring 43.

[0050] like Figure 11 The pushing component 8 includes an L-shaped roller 81 fixedly installed on the outer surface of the circular roller 64. A vertical plate 82 is slidably connected to the outer surface of the guide rail 12. A vertical groove 821 is opened at one end of the vertical plate 82 near the conical box 61. An inclined groove 822 communicating with the lower side of the inner surface of the vertical groove 821 is opened at one end of the vertical plate 82. One side of the outer surface of the L-shaped roller 81 is slidably connected to the inner surface of the vertical groove 821. A bending roller 83 is fixedly connected to one side of the upper end of the vertical plate 82.

[0051] Similarly, as hot water mixes with wheat lees and enters the conical box 61 and accumulates, the conical box 61, the fixed seat 62, the first round roller 63, and the second round roller 64 descend, which in turn drives the second L-shaped roller 81 to descend simultaneously. At this time, the outer surface of the second L-shaped roller 81 slides down along the inner surface of the vertical groove 821. Then, after the L-shaped roller 81 descends and slides to the connection between the inner surface of the vertical groove 821 and the inclined groove 822, the L-shaped roller 81 continues to slide down. Through the cooperation of the inclined groove 822, the vertical plate 82 slides along the outer surface of the guide rail 12 to the side away from the circular roller 64 during the descent of the L-shaped roller 81.

[0052] During the sliding process of the vertical plate 82, it will drive the bending roller 83 to move in the same direction. During the movement of the bending roller 83, it will push the upper side of the outer surface of the conical box 61, thereby causing the conical box 61 to tilt and rotate, pouring out the hot water mixed with wheat lees inside the conical box 61. During the tilting and rotation of the conical box 61, it will squeeze the elastic roller on one side and stretch the elastic roller on the other side.

[0053] After the conical box 61 is emptied, its own weight can no longer maintain the compression of the two telescopic rods 44 and the stretching of the telescopic rod 65. At this time, the hydraulic drive rod connected to the upper end of the telescopic rod 65 drives the entire telescopic rod 65 to rise, and the hydraulic drive rod connected to the lower end of the telescopic rod 44 pushes the telescopic rod 44 upward, causing the roller 63, the roller 64, the fixed seat 62 and the conical box 61 to rise simultaneously, which in turn causes the L-shaped roller 81 and the crossbar 45 to rise synchronously.

[0054] During the upward movement of L-shaped roller 81, it moves upward along the inner surface of inclined groove 822, thereby causing vertical plate 82 to move towards the side closer to circular roller 64. Similarly, during the movement of vertical plate 82, bending roller 83 moves in the same direction. Then bending roller 83 stops pressing on the outer surface of conical box 61, and the elastic roller that was pressed or stretched drives conical box 61 to reset, so that conical box 61 continues to maintain a vertical state.

[0055] Meanwhile, as the conical box 61 tilts, hot water mixed with wheat lees will continue to fall. After the conical box 61 returns to its original position, the falling hot water and wheat lees will continue to accumulate on the inner surface of the conical box 61, and the above steps will be repeated.

[0056] During the resetting process of the structures such as the first roller 63, the second roller 64, and the crossbar 45 by the two telescopic rods 44 and 65, the six thin ropes 42 are no longer under tension, while the six matching arc springs 43 remain compressed. Because the arc springs 43 deform under compression, the tension on the thin ropes 42 immediately disappears during the upward movement of the crossbar 45, but the deformation of the arc springs 43 does not immediately return to its original state; that is, the arc springs 43 remain compressed.

[0057] Furthermore, after the thin rope 42 is no longer under force, the compressed arc spring 43 pushes the L-shaped roller 41 to turn towards the upper end of the matching filter plate 31, filter plate 32, or filter plate 33, and rapidly taps the upper ends of the filter plate 31, filter plate 32, and filter plate 33. In the process of the L-shaped roller 41 tapping the filter plate 31 and other structures, on the one hand, it promotes the flow of wheat lees along the through holes to prepare for washing the lees, and on the other hand, it achieves self-cleaning of the filter plate 31, filter plate 32, and filter plate 33, ensuring that all the wheat lees on their upper ends fall into the washing process.

[0058] At the same time, the wheat lees are slowly mixed with hot water in a measured amount to further enhance the precipitation of sugars from the wheat lees.

[0059] That is, by mixing hot water with wheat lees, the combined gravity of the mixture, and through the cooperation of structures such as the conical box 61, the filter plates 31, 32, and 33 are struck, which promotes the falling of wheat lees and at the same time self-cleaning the filter plates 31 and other structures.

[0060] like Figure 12 The washing assembly 7 includes a sector-shaped box 71 fixedly installed on one side of the inner surface of the processing tank 1. A conical guide tube 73 is fixedly connected to the lower end of the sector-shaped box 71. The lower end of the conical guide tube 73 is located on the inner surface of the conical mixing tube 13. A filter plate 72 for filtering wheat lees is provided on the lower side of the inner surface of the sector-shaped box 71.

[0061] Furthermore, the hot water mixed with the lees is collected by the fan-shaped box 71. With the cooperation of the filter plate 72, the hot water for washing the lees is filtered and then passed through the inner surface of the conical guide tube 73 into the conical mixing tube 13, where it is mixed with the first batch of wort. The washed lees are then intercepted at the top of the filter plate 72.

[0062] The materials of each of the above structures will not react with wort or lees after being mixed with hot water.

[0063] Furthermore, after filtering a batch of mash, the mixed wort can be transported to the next process by opening the valve on the inner surface of the conical mixing cylinder 13.
