Description

Technical Field

[0001] This application relates to the field of beer production technology, and in particular to an acidification device and a beer saccharification system. Background Technology

[0002] In beer production, the saccharification process is the core step in wort preparation. It is used to convert the starch in malt into fermentable sugars, such as maltose, while extracting soluble substances such as proteins and polyphenols to provide the necessary raw materials for the subsequent fermentation process.

[0003] In related technologies, the saccharification apparatus includes a saccharification tank, a gelatinization tank, and a filter tank. The saccharification tank processes the mash, formed by mixing crushed malt and water, to extract fermentable sugars. The gelatinization tank boils unmalted grains (such as rice or corn) to form a starch gel, which is then mixed with a portion of the malt mash and fed into the saccharification tank for further saccharification. The filter tank separates the saccharified wort from the mash and recovers residual sugars through washing. During operation, the pH of the malt mash can be optimized by manually adding lactic acid or a lactic acid regulator to the saccharification tank and gelatinization tank, thereby improving enzyme activity, saccharification efficiency, and the final beer flavor.

[0004] However, adding lactic acid or lactic acid regulators in the above manner is rather inconvenient. Utility Model Content

The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0038] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0039] In beer production, the saccharification process is the core step in wort preparation. It is used to convert the starch in malt into fermentable sugars, such as maltose, while extracting soluble substances such as proteins and polyphenols to provide the necessary raw materials for the subsequent fermentation process.

[0040] In related technologies, the saccharification apparatus includes a saccharification tank, a gelatinization tank, and a filter tank. The saccharification tank processes the mash, formed by mixing crushed malt and water, to extract fermentable sugars. The gelatinization tank boils unmalted grains (such as rice or corn) to form a starch gel, which is then mixed with a portion of the malt mash and fed into the saccharification tank for further saccharification. The filter tank separates the saccharified wort from the mash and recovers residual sugars through washing. During operation, the pH of the malt mash can be optimized by manually adding lactic acid or a lactic acid regulator to the saccharification tank and gelatinization tank, thereby improving enzyme activity, saccharification efficiency, and the final beer flavor.

[0041] However, when adding lactic acid or lactic acid regulators using the above method, workers need to wear protective equipment to pour the acid in order to avoid skin irritation from contact with lactic acid, increasing the complexity of the operation. Furthermore, since lactic acid or lactic acid regulators are usually stored in large drums or cans, moving and emptying these containers requires considerable physical effort, and a single saccharification process requires workers to pour the acid multiple times to complete the addition of lactic acid. Therefore, the above method is inconvenient and labor-intensive.

[0042] In view of this, embodiments of this application provide an acid-adding device and a beer mashing system. The acid-adding device comprises an acid-adding component and a control component. The acid-adding component includes an acid-adding element and at least one first pipe. The control component includes a control element, at least one first control valve, and at least one second control valve. The acid-adding element is connected to the mashing pot and / or gelatinizing pot via the first pipe. The first control valve is located on the first pipe, and the second control valve is located on the feed pipe of the mashing pot and / or gelatinizing pot. The second control valve controls the opening and closing of the feed pipe. When the feed pipe is connected, it supplies mash to the mashing pot and / or gelatinizing pot. The control element controls the opening of the first control valve after the second control valve controls the feed pipe to be connected. The acid-adding element supplies acid to the mashing pot and / or gelatinizing pot via the first pipe when the first control valve is open. In this way, acid can be automatically added to the saccharification pot and / or gelatinization pot after feeding is completed, thereby reducing the need for manual acid addition to the saccharification pot and / or gelatinization pot, making acid addition convenient and reducing labor intensity.

[0043] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0044] See Figure 1 and Figure 2 The acid-adding device provided in this application embodiment includes an acid-adding component 100 and a control component 200. The acid-adding component 100 includes an acid-adding element 110 and at least one first pipe 120. The acid-adding element 110 is used to communicate with a saccharification pot 400 and / or a gelatinization pot 500 through the first pipe 120. The control component 200 includes a control element 210, at least one first control valve 220, and at least one second control valve 230. Both the first control valve 220 and the second control valve 230 are electrically connected to the control element 210. A control valve 220 is installed on the first pipe 120. A second control valve 230 is installed on the feed pipe 700 of the saccharification pot 400 and / or the gelatinization pot 500. The second control valve 230 is used to control the opening and closing of the feed pipe 700. A control element 210 is used to control the first control valve 220 to open after the second control valve 230 controls the feed pipe 700 to open. An acid-adding element 110 is used to supply acid to the saccharification pot 400 and / or the gelatinization pot 500 through the first pipe 120 when the first control valve 220 is open.

[0045] It should be noted that the acid-adding device in this embodiment can automatically add acid only to the saccharification pot 400, automatically add acid only to the gelatinization pot 500, or automatically add acid to both the saccharification pot 400 and the gelatinization pot 500. Automatic acid addition via the acid-adding device reduces the need for manual addition of acid to the saccharification pot 400 and / or the gelatinization pot 500, making acid addition convenient and reducing labor intensity.

[0046] The acid-adding unit 110 serves as the main acid storage and supply unit, connected to the first pipe 120 to provide the required acid to the saccharification pot 400 and / or the gelatinization pot 500. For example, the acid can be lactic acid or a lactic acid regulator, depending on the actual process requirements; this embodiment does not impose such limitations. Lactic acid, as a weak organic acid, can effectively regulate the pH value of the mash during fermentation and can be metabolized and utilized by the human body, exhibiting good safety.

[0047] By installing a first control valve 220 on the first pipeline 120 and electrically connecting the first control valve 220 to the control element 210, the first control valve 220 is used to precisely control the timing of acid delivery, so that the acid addition device can supply acid to the saccharification pot 400 and / or the gelatinization pot 500 when needed.

[0048] Specifically, a second control valve 230 is installed on the feed pipe 700 of the saccharification pot 400 and / or the gelatinization pot 500. The second control valve 230 is electrically connected to the control component 210. The second control valve 230 can control the opening and closing of the feed pipe 700 by means of manual or automatic control. When the feed pipe 700 is open, it will supply the mash to be saccharified to the saccharification pot 400 and / or the gelatinization pot 500. The control unit 210 receives a signal from the second control valve 230 to control the connection of the feed pipe 700. After the feed pipe 700 is connected, for example, according to process requirements, after the feed pipe 700 supplies mash to be saccharified to the saccharification pot 400 and / or the gelatinization pot 500 for 5 minutes, the control unit 210 controls the first control valve 220 to open, so that when the first control valve 220 is opened, the acid addition unit 110 supplies acid to the saccharification pot 400 and / or the gelatinization pot 500 through the first pipe 120.

[0049] For example, the specific number of the first pipe 120, the first control valve 220, and the second control valve 230 can be adaptively set according to the actual number of saccharification pots 400 and / or gelatinization pots 500 in production, such as... Figure 1As shown, there are two saccharification pots 400 and two gelatinization pots 500. The number of first pipes 120, first control valves 220 and second control valves 230 can be set to four. The acid-adding component 110 is connected to one saccharification pot 400 through one of the four first pipes 120. One end of the remaining first pipes 120 is connected to one of the four first pipes 120, and the other end is connected to the other saccharification pot 400 and the two gelatinization pots 500 respectively. The first control valves 220 are set on the first pipes 120 respectively. The two second control valves 230 are respectively set on the feed pipes 700 corresponding to the two saccharification pots 400. The other two second control valves 230 are respectively set on the feed pipes 700 corresponding to the two gelatinization pots 500.

[0050] Alternatively, the number of first pipes 120 and second control valves 230 can both be set to four, and the number of first control valves 220 can be set to one. In this way, unlike the previous arrangement, the first control valve 220 is set on only one of the four first pipes 120. The first control valve 220 is controlled to open by the control component 210, so that a passage is formed between the acid adding component 110 and each of the first pipes 120, so as to supply acid to the corresponding saccharification pot 400 and gelatinization pot 500 through each first pipe 120.

[0051] The specific type of the first control valve 220 is not limited in the embodiments of this application. For example, the first control valve 220 can be an electric control valve, such as an electric ball valve, an electric butterfly valve or an electric regulating valve; the first control valve 220 can also be a pneumatic control valve, such as a pneumatic ball valve, a pneumatic butterfly valve or a pneumatic diaphragm valve.

[0052] In specific implementation, such as Figure 2 As shown, the control unit 210 includes a controller 211 and a time delay relay 212 electrically connected to the controller 211. The first control valve 220 is electrically connected to the controller 211. The second control valve 230 includes a valve body 231 and a limit switch 232 disposed on the valve body 231. The valve body 231 is electrically connected to the time delay relay 212 through the limit switch 232. The limit switch 232 is used to detect whether the valve body 231 is open. The time delay relay 212 is configured to delay for a preset time when the limit switch 232 detects that the valve body 231 is open, so as to control the first control valve 220 to open through the controller 211.

[0053] Among them, the controller 211 is the core control unit of the acid addition device. The controller 211 is responsible for receiving signals from the limit switch 232, executing the instructions of the time delay relay 212, and finally controlling the opening and closing of the first control valve 220. After receiving the valve body 231 opening signal from the limit switch 232, the time delay relay 212 delays the time for a preset time, which can be 5 minutes, and then sends a signal to the PLC to trigger the opening of the first control valve 220.

[0054] Specifically, the second control valve 230 includes a valve body 231 and a limit switch 232 disposed on the valve body 231. The limit switch 232 is used to detect whether the valve body 231 is open and transmits a signal to the time delay relay 212. In this way, through the cooperation of the limit switch 232 and the time delay relay 212, it is ensured that the delay timing and subsequent operation will only start when the valve body 231 is open, reducing the occurrence of malfunctions due to signal errors.

[0055] Overall, the acid addition process, which can be completed without manual operation through the above design, not only helps to improve production efficiency, but also reduces the risk of human error.

[0056] In actual production, to ensure the enzymes in the mash maintain good activity, it is necessary to control the amount of acid supplied to the saccharification tank 400 and / or gelatinization tank 500 via the acidification device, so that the pH value of the mash is maintained within an appropriate range, such as 5.2-5.4. (See also...) Figure 1 and Figure 3 In some embodiments, the control component 200 further includes a flow detection element 270 electrically connected to the control component 210. The flow detection element 270 is used to detect whether the flow rate of acid supplied by the acid adding element 110 to the saccharification pot 400 and / or the gelatinization pot 500 reaches a preset value. The control component 210 is also configured to control the first control valve 220 to close when the flow detection element 270 detects that the flow rate of acid supplied by the acid adding element 110 to the saccharification pot 400 and / or the gelatinization pot 500 reaches the preset value.

[0057] Thus, by monitoring the acid flow rate during the acid addition process through the flow detection device 270, when the acid flow rate reaches the preset value, the control device 210 will close the first control valve 220 to stop the supply of acid, thereby accurately controlling the amount of acid added to the mash.

[0058] It should be noted that the preset values ​​in the embodiments of this application can be set according to actual process requirements, as long as the pH value of the mash can maintain good enzyme activity when the acid flow rate reaches the preset value.

[0059] For example, in a specific implementation, the acid is added starting 5 minutes after feeding into the saccharification tank 400 and / or the gelatinization tank 500, and is added before the feeding ends, in order to avoid subsequent pH fluctuations affecting the enzyme reaction.

[0060] The specific type of the flow detection element 270 is not limited in this application embodiment. For example, the flow detection element 270 can be an electromagnetic flow meter, a differential pressure flow meter or an ultrasonic flow meter.

[0061] In practice, after separating the wort from the spent grains in the mashed beer through the filter tank 600, a wash water supply pipe 800 supplies wash water to the filter tank 600. Rinsing the filter tank 600 with this wash water helps extract residual fermentable sugars, improving the saccharification yield. The wash water is typically heated to 75-78°C. Because the pH of the wash water is relatively high (>6.0), it can leach bitter substances such as tannins and polyphenols from the spent grains, affecting the beer's flavor. Therefore, please refer to... Figure 4 In some examples, the acid-adding assembly 100 also includes a second conduit 130, through which the acid-adding component 110 is connected to the washing water supply conduit 800; the acid-adding component 110 is also used to deliver acid to the washing water supply conduit 800 through the second conduit 130.

[0062] With this setup, the acid-adding component 110 adds acid to the washing tank water through the second pipe 130 to lower its pH value, which can effectively prevent the dissolution of bitter substances such as tannins and polyphenols from the malt, thereby maintaining the pure flavor of the beer.

[0063] Specifically, in combination Figure 3 As shown, the control assembly 200 also includes a pH sensor 280 and a third control valve 240. The third control valve 240 is disposed on the second pipe 130. Both the pH sensor 280 and the third control valve 240 are electrically connected to the control assembly 210. The pH sensor 280 is used to detect the pH value of the liquid in the washing water supply pipe 800. The control assembly 210 is used to control the opening and closing of the third control valve 240 according to the pH value.

[0064] In this way, real-time monitoring and automatic adjustment of the pH value of the liquid in the washing tank water supply pipeline 800 can be achieved, reducing the need for manual intervention and reducing errors caused by improper human operation; in addition, the time required for manual pH adjustment is reduced, making the production process more efficient and improving production efficiency.

[0065] For other examples, see Figure 4The control component 200 also includes a conductivity meter 290 and a fourth control valve 250. The fourth control valve 250 is disposed on the second pipe 130. Both the conductivity meter 290 and the fourth control valve 250 are electrically connected to the control component 210. The conductivity meter 290 is used to detect the conductivity value of the liquid in the washing tank water supply pipe 800. The control component 210 is used to control the opening and closing of the fourth control valve 250 according to the conductivity value.

[0066] It is understandable that by measuring the conductivity of the liquid in the washing tank water supply pipe 800 using a conductivity meter 290, the conductivity of the liquid can be reflected, such as the presence of charged ions in the liquid. , The total concentration of lactate, etc., and the higher the ion concentration, the greater the conductivity.

[0067] Thus, by adding acid to the washing tank water to adjust the pH value, the ionic composition is changed, which in turn causes fluctuations in the liquid conductivity. The conductivity value of the liquid in the washing tank water supply pipe 800 is detected by the conductivity meter 290, and the control component 210 controls the opening and closing of the fourth control valve 250 according to the conductivity value to adjust the pH value of the washing tank water. This reduces the need for manual intervention and reduces errors caused by improper human operation. In addition, it reduces the time required for manual pH adjustment, making the production process more efficient and improving production efficiency.

[0068] See Figure 1 and Figure 5 In some examples, the acid-adding component 110 includes an acid-adding component body 111 and a delivery pump 112. The acid-adding component body 111 has a receiving cavity 1111 for holding acid. The outlet of the acid-adding component body 111 is connected to the first pipe 120 through the delivery pump 112. The delivery pump 112 is used to draw the acid in the receiving cavity 1111 through the first pipe 120 to the saccharification pot 400 and / or the gelatinization pot 500 when the first control valve 220 is opened.

[0069] The acid-adding component body 111 serves as an acid storage unit, and its accommodating cavity 1111 is used to hold the acid solution. The delivery pump 112 is installed at the outlet of the acid-adding component body 111 to draw the acid solution from the acid-adding component body 111 to the first pipe 120 and deliver it to the saccharification pot 400 and / or the gelatinization pot 500, providing power for the flow of the acid solution and ensuring that the acid solution can be smoothly delivered to the saccharification pot 400 and / or the gelatinization pot 500.

[0070] Exemplarily, the transfer pump 112 includes a pump body and a motor connected to the pump body. The motor drives the pump body to open and close. The motor is electrically connected to the control unit 210. When the control unit 210 controls the first control valve 220 to open, it controls the motor to drive the pump body to start, so as to draw acid in the receiving chamber 1111 through the first pipe 120 to the saccharification pot 400 and / or the gelatinization pot 500. And when the control unit 210 controls the second control valve 230 to close, it controls the motor to drive the pump body to close. In this way, the pump body operates only when needed, achieving the effect of energy saving and reducing operating costs. The pump body can be a centrifugal pump, diaphragm pump, etc., and this application embodiment does not limit this.

[0071] To facilitate regular cleaning of the acid-treated component body 111 and reduce contamination, please refer to... Figure 5 In some embodiments, the acid addition device further includes a cleaning assembly 300, which includes a cleaning component 310, a collecting component 320, and a plurality of washing balls 330. Each washing ball 330 is located within a receiving cavity 1111, and the cleaning component 310 is connected to each washing ball 330. The cleaning component 310 contains cleaning fluid and is used to sequentially deliver the cleaning fluid to the plurality of washing balls 330 and the receiving cavity 1111 to clean the cavity wall of the receiving cavity 1111. The collecting component 320 is connected to the bottom of the acid addition device body 111 and is used to collect the cleaning fluid after cleaning.

[0072] This configuration allows for regular cleaning of the cavity wall of the acid-adding component body 111, removing accumulated impurities and residues, preventing these contaminants from affecting the quality of subsequently added acid, and ensuring the purity and consistency of the acid.

[0073] The cleaning fluid in the cleaning component 310 can be water or a cleaning agent formulated according to actual process requirements; this embodiment does not impose any limitations on this. The cleaning component 310 serves as a storage and delivery unit for the cleaning fluid, used to sequentially deliver the cleaning fluid to multiple washing balls 330 and the receiving cavity 1111, such as... Figure 5 As shown, the cleaning component 310 is connected to each washing ball 330 via the fifth control valve 260. Thus, the flow rate and volume of the cleaning fluid can be adjusted as needed via the fifth control valve 260.

[0074] The cleaning ball 330 is located inside the receiving cavity 1111 and is used to spray cleaning fluid to thoroughly clean the cavity wall of the receiving cavity 1111. It can be understood that the cleaning ball 330 can generate high-pressure water flow or spray to cover a large area of ​​the cavity wall surface, ensuring cleaning without dead corners, and the design of multiple cleaning balls 330 makes the cleaning more uniform and thorough, reducing the accumulation of residue in local areas.

[0075] By connecting the collection component 320 to the bottom of the acid-adding component body 111, the cleaning fluid after cleaning is collected, thus providing a safe and environmentally friendly way to treat waste liquid and preventing the cleaning fluid from being discharged indiscriminately and causing environmental pollution.

[0076] Furthermore, the cleaning assembly 300 also includes a stirring component 340, which includes a stirring part 341 and a driving part 342; the acid adding component body 111 has a clearance hole that communicates with the receiving cavity 1111, and part of the stirring part 341 is placed in the receiving cavity 1111 through the clearance hole; the driving part 342 is connected to the stirring part 341 and is used to drive the stirring part 341 to rotate so that the stirring part 341 stirs the cleaning liquid in the receiving cavity 1111.

[0077] Thus, by driving the stirring unit 341 to rotate through the driving unit 342, the cleaning fluid can form a vortex or turbulence in the receiving cavity 1111, increasing the contact area and friction between the cleaning fluid and the cavity wall, thereby more effectively removing stains and residues from the cavity wall.

[0078] The stirring part 341 can use propeller-type or propeller-type stirring blades to stir the cleaning liquid, and the driving part 342 can drive the stirring part 341 to rotate by electric motor, pneumatic motor or other driving methods. This application embodiment does not limit this.

[0079] This application also provides a beer mashing system, including a system body and an acid-adding device as described in any of the above embodiments, disposed on the system body.

[0080] The overall structure and working principle of the acid addition device are the same as those in the aforementioned embodiments, and will not be repeated here.

[0081] The beer mashing system of this application embodiment includes an acid-adding device, which comprises an acid-adding component 100 and a control component 200. The acid-adding component 100 includes an acid-adding element 110 and at least one first pipe 120. The control component 200 includes a control element 210, at least one first control valve 220, and at least one second control valve 230. The acid-adding element 110 is connected to the mashing pot 400 and / or the gelatinizing pot 500 through the first pipe 120. The first control valve 220 is installed on the first pipe 120, and the second control valve 230 is installed on the feed pipe 700 of the mashing pot 400 and / or the gelatinizing pot 500. The second control valve 230 controls the opening and closing of the feed pipe 700. When the feed pipe 700 is connected, it supplies mash to be mashed to the mashing pot 400 and / or the gelatinizing pot 500. The control unit 210 is used to control the opening of the first control valve 220 after the second control valve 230 controls the connection of the feed pipe 700; the acid adding unit 110 is used to supply acid to the saccharification pot 400 and / or the gelatinization pot 500 through the first pipe 120 when the first control valve 220 is open. In this way, automatic acid adding to the saccharification pot 400 and / or the gelatinization pot 500 can be realized after the feeding of the saccharification pot 400 and / or the gelatinization pot 500 is completed, thereby reducing the need for manual acid addition to the saccharification pot 400 and / or the gelatinization pot 500, making acid addition convenient and reducing labor intensity.
