Description

Technical Field

[0001] The present application relates to the technical field of filtering devices, and in particular to a beer brewing filtering device and a filtering method. Background Art

[0002] During the beer brewing process, raw materials and the saccharification process produce substances that are potentially harmful to the quality of beer. Filtering and removing impurities from the beer wort after saccharification can effectively reduce the entry of these substances into the wort. By removing microorganisms and impurities in the wort, the chance of microorganisms breeding during subsequent fermentation and storage is reduced, thereby ensuring the quality and safety of the beer. However, existing filtration devices are only capable of single-time impurity removal and can only rely on a single filter medium for filtration.

[0061] Reference Figures 1-6 , a beer brewing filtering device includes a tank body 1, a filter box 2, a stirring assembly 3, a filter plate component 4 and a rotary pressing assembly 5. The tank body 1 is installed on the filter box 2, and an opening 11 communicating with the interior of the filter box 2 is provided at the bottom of the tank body 1. Support legs are provided around the bottom of the filter box 2. A wire sieve plate 12 is installed on the opening 11. The wort needs to pass through the wire sieve plate 12 during the process of flowing from the tank body 1 to the filter box 2, and impurities are filtered through the wire sieve plate 12. The stirring assembly 3 and the rotary pressing assembly 5 are respectively used to stir the wort. The tank body 1 is also provided with an opening and closing cover. By opening the opening and closing cover, the tank body 1 can be connected to the outside, so that the operator can easily scrape off the debris on the wire sieve plate 12;

[0062] The tank body 1 is provided with a top cover 13, and the top cover 13 is provided with a liquid inlet pipe 131 that is communicated with the interior, and the liquid inlet pipe 131 is connected to the rest of the tank body. The stirring assembly 3 includes a driving motor 31, a rotating shaft 32, a support rod 33 and a scraper member 34. The driving motor 31 is arranged on the top cover 13 and is connected to the rotating shaft 32. The driving motor 31 provides power for the rotation of the rotating shaft 32. The driving motor 31 and the rotating shaft 32 are connected by a coupling. The other end of the rotating shaft 32 is located on the wire screen plate 12 and is equipped with a bearing seat. A sleeve 321 is sleeved on the rotating shaft 32. The support rod 33 is provided with two groups and is symmetrical on both sides of the sleeve 321. Several scraper members 34 are provided and evenly distributed on the side of the support rod 33 facing the end face of the wire screen plate 12. One end of the scraper member 34 is against the end face of the wire screen plate 12. The scraper member 34 can scrape impurities attached to the wire screen plate 12 to avoid clogging on the wire screen plate 12.

[0063] Two groups of filter plate components 4 are provided and symmetrically distributed on both sides of the filter box 2. The filter plate components 4 include a mounting seat 41 and a filter plate 42. The aperture of the filter plate 42 is smaller than the aperture of the wire sieve plate 12. The filter plate 42 is installed in the mounting seat 41, and the mounting seat 41 is movably set in the filter box 2. A filter material area is formed between the two groups of filter plates 42. The bottom of the filter box 2 is connected to the discharge pipe 21 on both sides. A valve component is installed at the bottom of the discharge pipe 21. Since the wire sieve plate 12 is located between the two groups of filter plates 42, the wort must pass through the filter plate 42 when flowing to the discharge pipe 21.

[0064] The rotary material pressing assembly 5 is located in the filter material area and includes a driver 51, an output shaft 52, a sleeve 53 and an elastic pressure pad component 54. The driver 51 is arranged outside the filter box 2 and is connected to the output shaft 52 through a coupling. The output shaft 52 is located in the filter box 2. The sleeve 53 is installed on the outer periphery of the output shaft 52. The outer periphery of the sleeve 53 is connected to the elastic pressure pad component 54 through a connecting rod. There are several elastic pressure pad components 54 and they are spaced apart along the length direction of the sleeve 53. When the driver 51 is started, the elastic pressure pad component 54 rotates along the rotation direction of the driver 51 in cooperation with the output shaft 52.

[0065] The elastic pressure pad component 54 includes a pad 541. In cooperation with the output shaft 52, several pads 541 are respectively pressed against the end face of the filter plate 42 and the bottom of the filter box 2. When impurities in the wort are located between the filter plate 42 and the pad 541, the impurities can be further crushed by squeezing the pad 541.

[0066] The filter box 2 is provided with a wire mesh plate 12, so that the wort in the tank body 1 needs to pass through the wire mesh plate 12 and flow into the filter box 2. During the flow, the impurities in the wort will be blocked by the wire mesh plate 12. In addition, since the tank body 1 is provided with a rotating shaft 32 connected to the drive motor 31, the sleeve 321 installed on the rotating shaft 32 is connected to the scraper member 34 through the support rod 33. When the rotating shaft 32 rotates in cooperation with the drive motor 31, the scraper member 34 and the support rod 33 can stir the wort. For natural sedimentation and impurity removal, stirring can break the local equilibrium that may be formed during the precipitation of impurities, making it easier for impurity particles to gather and settle to the bottom of the container, and the scraper member 34 can prevent the impurities on the wire mesh plate 12 from accumulating and clogging, so that the wort can pass more smoothly, thereby realizing the preliminary filtration and impurity removal of the wort.

[0067] When the wort flows into the filter box 2, the wort is located between the two groups of filter plates 42, so that when the wort flows into the discharge pipe 21, it needs to pass through the filter plate 42 to complete the re-filtration of the wort. And because the rotary pressing assembly 5 is located in the filter box 2, when the wort is located between the two groups of filter plates 42, the output shaft 52 drives the pad 541 in the elastic pressure pad component 54 to move through the shaft sleeve 53. The pad 541 can not only stir the wort again, but also can be abutted against the filter plate 42 and the end face of the filter box 2, so as to squeeze out some impurity particles in the wort, thereby realizing further grinding of the wort. The wire sieve plate 12 and the filter plate 42 can realize double impurity removal operation of the wort, thereby improving the purity of the wort after impurity removal, and solving the problem that the existing impurity removal device only has single-layer filtration and causes poor impurity removal effect.

[0068] The driving motor 31 and the driver 51 are both servo driving motors in the prior art.

[0069] In one embodiment, referring to Figure 1 ,picture, Figure 3 and Figure 9 , further comprising a telescopic baffle assembly 6, the telescopic baffle assembly 6 comprising a first push rod component 61, a support plate 62 and a sealing gasket 63, two groups of first push rod components 61 are provided and symmetrically distributed on the filter box 2 and located on both sides of the tank body 1, and the first push rod components 61 adopt any one of a pneumatic push rod, an electric push rod or a hydraulic push rod in the prior art;

[0070] The piston end of the first push rod component 61 extends into the interior of the filter box 2 and is connected to the support plate 62. The two ends of the sealing gasket 63 are respectively connected to the two sets of support plates 62. The sealing gasket 63 is made of rubber material and has a certain degree of ductility and deformation performance.

[0071] The area of ​​the sealing gasket 63 is the same as that of the opening 11. The sealing gasket 63 is moved closer to or away from the opening 11 through the cooperation of the first push rod component 61. When the sealing gasket 63 is close to the opening 11, the sealing gasket 63 is embedded in the opening 11 and covers the wire screen plate 12, so that the tank body 1 and the filter box 2 are sealed to each other. When the sealing gasket 63 is away from the opening 11, a flow gap is formed between the tank body 1 and the filter box 2. Since impurity removers are added for chemical impurity removal during the impurity removal process, the flocculation reaction rate is accelerated, and impurities form precipitation or flocs more quickly, which is convenient for subsequent separation and removal. Therefore, the opening 11 is covered by the sealing gasket 63 to prevent the wort from flowing from the wire screen plate 12 to the filter box 2 when it is in the tank body 1. When overflow is required, the sealing gasket 63 is moved away from the opening 11, so that the wort can flow, which can be adjusted according to actual conditions and improves flexibility.

[0072] In one embodiment, referring to Figure 1 、 Figure 5 、 Figure 6 and Figure 10 The elastic pressure pad component 54 also includes a bearing seat 542 and an elastic member 543. The bearing seat 542 is connected to the connecting rod. The bearing seat 542 has a groove. A plurality of elastic members 543 are provided and spaced apart along the length direction of the groove. The elastic member 543 is a telescopic spring or a pressure spring in the prior art.

[0073] One end of the elastic member 543 is connected to the end face of the groove, and the other end is connected to the pad 541. The pad 541 is moved away from one end of the elastic member 543 to be close to or away from the groove. The setting of several elastic members 543 can disperse the pressure borne by the pad 541 when it is under pressure. When the mounting seat 41 drives the filter plate 42 to move, the distance between the pad 541 in the elastic pressure pad component 54 and the filter plate 42 will change. Therefore, through the setting of the elastic member 543, the pad 541 can be changed in position with the cooperation of the elastic member 543, so that it can be suitable for filter plate components 4 with different moving distances.

[0074] In one embodiment, referring to Figure 1 , pictures and Figure 8 , also includes a cleaning assembly 7, the cleaning assembly 7 includes a guide pipe 71, a first nozzle component 72 and a second nozzle component 73, the guide pipe 71 is arranged on the top of the mounting seat 41, and the first nozzle component 72 and the second nozzle component 73 are provided with a plurality of and spaced apart on both sides of the guide pipe 71, the first nozzle component 72 and the second nozzle component 73 both adopt the horn nozzle in the prior art, and the first nozzle component 72 and the second nozzle component 73 are staggered, and the first nozzle component 72 and the second nozzle component 73 can evenly clean the inner wall of the filter box 2;

[0075] The flow guide pipe 71 has a liquid inlet interface, which is connected to the telescopic tube 74. The other end of the telescopic tube 74 extends to the outside of the filter box 2 and is connected to an external water source. Since the flow guide pipe 71 is installed on a movable mounting seat 41, it is connected to the telescopic tube 74 through the liquid inlet interface. When the mounting seat 41 drives the flow guide pipe 71 to move, the telescopic tube 74 can be extended and retracted according to the moving position of the mounting seat 41.

[0076] In one embodiment, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 9 The filter plate component 4 also includes a second push rod component 43. The second push rod component 43 adopts any one of the pneumatic push rods, electric push rods or hydraulic push rods in the prior art. The second push rod component 43 is arranged on both sides of the filter box 2, and is vertically distributed between the second push rod component 43 and the first push rod component 61. The piston end of the second push rod component 43 passes through the filter box 2 and is connected to the filter plate 42. The second push rod component 43 can drive the filter plate 42 to move, and the moving distance of the filter plate 42 can be accurately controlled.

[0077] In one embodiment, referring to Figure 1 、 Figure 5 、 Figure 6 and Figure 10 The elastic pressure pad component 54 further includes a scraping plate 544 , a mounting hole 5411 is provided on the side of the pad 541 away from the elastic member 543 , and a connecting rod 5441 matching the mounting hole 5411 is provided at the bottom of the scraping plate 544 ;

[0078] By installing the connecting rod 5441 in the mounting hole 5411, the scraper plate 544 is installed on the pad 541. The connection between the mounting hole 5411 and the connecting rod 5441 is provided with mutually matching threads, so that the connecting rod 5441 can be threadedly connected to the mounting hole 5411. The threaded connection method can fix the scraper plate 544 on the pad 541, thereby preventing the scraper plate 544 from shaking and falling during rotation, and improving the stability of the scraper plate 544 during installation.

[0079] In one embodiment, referring to Figure 1-Figure 4 An auxiliary material pipe 14 is provided on the top of the tank body 1. One end of the auxiliary material pipe 14 is connected to the interior of the tank body 1. A closing cover 141 is hinged on the auxiliary material pipe 14. The auxiliary material pipe 14 can be filled with other materials or inert gas. Nitrogen and carbon dioxide can be used as inert gas, and the closing cover 141 can seal the auxiliary material pipe 14 to prevent the internal and external gases from circulating during impurities removal, thereby affecting the quality of wort.

[0080] In one embodiment, referring to Figure 2 、 Figure 5 and Figure 7 A material guide seat 411 is also provided at the bottom of the mounting seat 41. The bottom of the material guide seat 411 is against the end face of the filter box 2. Both ends of the material guide seat 411 are provided with inclined end portions 4111. Since the mounting seat 41 can move with the cooperation of the second push rod component 43, the wort can be pushed through the material guide seat 411, and the setting of the inclined end portion 4111 can improve the guidance of the material guide seat 411 for pushing.

[0081] In one embodiment, referring to Figure 1 and Figure 4 A temperature detection component 8 is also installed on the tank body 1. The detection end of the temperature detection component 8 is located inside the tank body 1. The temperature detection component 8 is a temperature sensor with an Internet communication function in the prior art. The solubility of certain impurities is different at different temperatures. During the filtration and impurity removal process, if the temperature fluctuates greatly, the impurities that have been precipitated or intercepted by the filter medium may be redissolved in the wort, resulting in a decrease in the filtration effect, thereby ensuring the filtration effect.

[0082] The embodiment of the present application provides a beer brewing filtration device as described above, and the filtration method includes the following steps: S1: transporting wort to the tank body 1 through a pipeline, and the wire sieve plate 12 is abutted against the sealing gasket 63 under the cooperation of the first push rod component 61, so that the support rod 33 and the scraper component 34 in the stirring assembly 3 are stirred. When filtering and removing impurities, moderate stirring can prevent the accumulation and blockage of impurities on the surface of the filter medium. Stirring helps to evenly distribute the temperature of the beer liquid, avoid inconsistent impurity removal reactions caused by excessively high or low local temperatures, and affect the overall impurity removal effect. The stirring time can be selected from 30 minutes to 2 hours according to the temperature conditions, and different temperatures have an impact on the stirring time.

[0083] S2: After the stirring is completed, the sealing gasket 63 is separated from the sieve plate 12 under the cooperation of the first push rod component 61, so that the wort passes through the wire sieve plate 12 and flows into the filter box 2. Impurities in the wort are initially separated under the action of the wire sieve plate 12. Impurities larger than the size of the wire sieve plate 12 will be initially blocked by the wire sieve plate 12, so that the wort in the filter box 2 has been preliminarily cleaned of impurities;

[0084] S3: The output shaft 52 in the filter box 2 rotates in cooperation with the driver 51, thereby driving the elastic pressure pad component 54 to rotate in the circumferential direction, so that the wort in the filter box 2 is stirred again by the rotating elastic pressure pad component 54. In the process of rotation, the elastic pressure pad component 54 comes into contact with some fine malt particles, thereby crushing the malt particles, thereby squeezing out the remaining wort, and stirring and crushing the wort that has been preliminarily cleaned of impurities again, thereby accelerating the precipitation of impurities and improving the clarity of the wort.

[0085] S4: The wort in the filter box 2 is between two groups of filter plates 42. The wort flows into the discharge pipes 21 on both sides through the sieve holes of the filter plates 42 on both sides.
