Description

Technical Field

[0001] This application relates to the field of biological and fermentation engineering and equipment technology, and in particular to a beer saccharification apparatus. Background Technology

[0002] In beer production, the mashing pot, also known as the malt cooker, is primarily used to process the mash formed by mixing crushed malt and water to extract fermentable sugars. Providing the mash with the appropriate temperature to promote the conversion of starch into sugars is crucial for ensuring the quality of the final beer.

[0003] In related technologies, the saccharification pot includes a pot body, and heating belts are provided in the middle and lower sections and the outer side of the bottom of the pot body. By introducing steam generated by an external steam generator into the heating belts, the steam exchanges heat with the pot body through the heat exchange surface of the heating belts, thereby heating the mash inside the pot.

[0004] However, in some application scenarios, when the above heating method is used to heat the mash, there are problems such as unreasonable steam utilization and low heating efficiency. Utility Model Content

[0022] A steam branch pipe assembly includes at least two steam branch pipes, each corresponding to an inlet. The inlet is connected to a steam supply component through the corresponding steam branch pipe, and an air inlet valve is installed on each steam branch pipe.

[0023] A condensate branch pipe assembly includes at least two condensate branch pipes, each corresponding to an outlet, and the outlet is connected to a condensate collection device through the corresponding condensate branch pipe.

[0024] In one possible implementation, the beer mashing apparatus provided in this application includes a steam supply unit comprising a supply unit body and a delivery pump, wherein the supply unit body is connected to each steam branch pipe via the delivery pump.

The heat exchange unit is fitted around the periphery of the pot body and extends along the height of the pot body. By opening at least two inlets and at least two outlets on the heat exchange unit, with the outlets and inlets alternately arranged along the height direction and corresponding one-to-one, a channel is formed between any inlet and the corresponding outlet for heat exchange between steam and the periphery of the pot body. In this way, the arrangement of each channel satisfies the steam heating of mash at different liquid levels in the pot body, thereby eliminating the need to extend the heating time and improving heating efficiency.

[0030] By setting at least two air inlet valves, each inlet is paired with an air inlet valve, connecting the inlet to the steam supply unit. Each outlet is connected to a condensate collection unit.

The condensate formed after steam heat exchange is recovered to the condensate collection unit through the corresponding outlet of each channel. The beer mashing device provided in this application achieves efficient steam utilization and high heating efficiency. Attached Figure Description

[0049] 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.

[0050] In beer production, the mashing pot, also known as the malt cooker, is primarily used to process the mash formed by mixing crushed malt and water to extract fermentable sugars. Providing the mash with the appropriate temperature to promote the conversion of starch into sugars is crucial for ensuring the quality of the final beer.

[0051] In related technologies, the saccharification pot includes a pot body, and heating belts are provided in the middle and lower sections and the outer side of the bottom of the pot body. By introducing steam generated by an external steam generator into the heating belts, the steam exchanges heat with the pot body through the heat exchange surface of the heating belts, thereby heating the mash inside the pot.

[0052] However, in some applications, such as when the mash in the pot only covers the bottom area (i.e., the mash level is lower than the middle and lower sections of the pot), some of the steam delivered to the heating zone by the steam generator will dry-burn the pot without effectively exchanging heat with the mash. This results in wasted steam and potential damage to the pot from dry burning. Conversely, when the mash covers the upper and middle sections of the pot, and the mash level is higher, it's understandable that delivering steam to the heating zone requires a longer steam supply time for heat transfer to fully heat the mash above the upper and middle sections. Therefore, using these heating methods for mash heating results in inefficient steam utilization and low heating efficiency.

[0053] In view of this, this application provides a beer mashing apparatus, which includes a pot body and a heating component. The heating component comprises a steam supply unit, a heat exchange unit, and a condensate collection unit. The heat exchange unit is fitted around the periphery of the pot body and extends along the height of the pot body. At least two inlets and at least two outlets are provided on the heat exchange unit, with the inlets and outlets alternately arranged along the height direction and corresponding one-to-one. The heat exchange unit forms a channel between any inlet and its corresponding outlet for heat exchange between steam and the periphery of the pot body. Thus, the arrangement of these channels satisfies… Steam heating of mash at different liquid levels within the pot eliminates the need for extended heating time, thus improving heating efficiency. By installing at least two air inlet valves, with each inlet corresponding to a steam supply unit, and each outlet connected to a condensate collection unit, steam can be supplied only to channels corresponding to the mash coverage area by manipulating the air inlet valves. This avoids steam waste, and the condensate formed after steam heat exchange is recovered to the condensate collection unit through the corresponding outlet of each channel. The beer mashing apparatus provided in this application achieves efficient steam utilization and high heating efficiency.

[0054] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0055] See Figures 1 to 3The beer mashing apparatus provided in this application includes a pot body 100, a heating component 200, and a valve component 300. The heating component 200 includes a steam supply component 210, a heat exchange component 220, and a condensate collection component 230. The heat exchange component 220 is sleeved on the periphery of the pot body 100 and extends along the height direction of the pot body 100. The heat exchange component 220 has at least two inlets 221 and at least two outlets 222. The outlets 222 and inlets 221 are alternately arranged along the height direction. The inlets 221 and outlets 222 correspond one-to-one. The heat exchange component 220 forms a channel 223 between any inlet 221 and the corresponding outlet 222 for heat exchange between steam and the periphery of the pot body 100. Each outlet 222 is connected to the condensate collection component 230.

[0056] The valve assembly 300 includes at least two inlet valves 310, and an inlet 221 corresponds to an inlet valve 310. The inlet 221 is connected to the steam supply unit 210 through the corresponding inlet valve 310.

[0057] Specifically, by setting up a heat exchanger 220 that extends along the height of the pot body 100, it is ensured that the heat exchanger 220 can cover mash areas at different liquid levels. The steam supply position can be flexibly adjusted according to the actual liquid level, avoiding waste of some steam that does not come into contact with the mash. By opening inlets 221 and outlets 222 alternately along the height direction on the heat exchanger 220, a channel 223 is formed between any inlet 221 and the corresponding outlet 222 for steam to exchange heat with the periphery of the pot body 100. This ensures that the steam can be evenly distributed in the channel 223 at different heights, so that the mash at each height segment can be fully heated, reducing heating time and improving heat exchange efficiency.

[0058] By setting the air inlet valve 310, the corresponding air inlet valve 310 can be selectively opened according to the height of the mash in the pot body 100, so as to flexibly control the steam supply of each inlet 221, ensuring that steam is only supplied to the area covered by the liquid, and avoiding dry burning and steam waste.

[0059] By connecting each outlet 222 to the condensate collection unit 230, the condensate after heat exchange can be effectively recovered, preventing condensate from accumulating in the system and affecting heat exchange efficiency. At the same time, the condensate can be reused or treated, improving resource utilization.

[0060] For example, the height direction of the pot body 100 is... Figure 1The Z direction shown, i.e., the direction from bottom to top, is the opposite direction of gravity. The pot body 100 can be divided into a first region and a second region from bottom to top. The heat exchanger is fitted around the periphery of the pot body 100. The heat exchanger 220 has an inlet 221 and an outlet 222 near the upper and lower edges of the first region, respectively, and an inlet 221 and an outlet 222 near the upper and lower edges of the second region, respectively. That is, there are two inlets 221 and two outlets 222, and the outlets 222 and inlets 221 are arranged alternately from bottom to top.

[0061] Thus, the air inlet valve 310 corresponding to each inlet 221 is normally open. When the mash in the pot body 100 is located in the first area, the air inlet valve 310 corresponding to the inlet 221 near the upper edge of the second area can be operated to close. When the mash in the pot body 100 is located in the second area and covers the first area, no operation is required, so that the air inlet valve 310 corresponding to both inlets 221 remains open.

[0062] In other examples, the pot body 100 can be divided into a third region, a fourth region, and a fifth region from bottom to top. The heat exchanger 220 has inlets 221 and outlets 222 at positions near the upper and lower edges of the third region, the upper and lower edges of the fourth region, and the upper and lower edges of the fifth region, respectively. That is, there are three inlets 221 and three outlets 222, and the outlets 222 and inlets 221 are arranged alternately from bottom to top.

[0063] Thus, the air inlet valve 310 corresponding to each inlet 221 is normally open. When the mash in the pot body 100 is located in the third region, the air inlet valve 310 corresponding to the inlet 221 near the upper edge of the fourth region and the inlet 221 near the upper edge of the fifth region can be closed. When the mash in the pot body 100 is located in the fourth region and covers the third region, the air inlet valve 310 corresponding to the inlet 221 near the upper edge of the fifth region can be closed.

[0064] Of course, it is understood that the number of inlet 221 and outlet 222 in this embodiment can also be set as follows, depending on actual needs. Figure 1 The four shown can also be set to five, etc. The specific usage is the same as in the above embodiments, and this application embodiment will not repeat it.

[0065] It should be noted that the intake valve 310 in this embodiment can be configured as a pneumatic valve. The pneumatic valve drives the piston or diaphragm with compressed air to open and close the valve core. Its structure is relatively simple and easy to maintain. The intake valve 310 can also be configured as a manual valve. The valve core can be opened and closed by manually rotating the handwheel or handle. Its structure is simple and the operation is intuitive.

[0066] In summary, the beer mashing apparatus provided in this application embodiment has a heat exchanger 220 forming a channel 223 between any inlet 221 and the corresponding outlet 222 for steam to exchange heat with the periphery of the pot body 100. Thus, the arrangement of each channel 223 satisfies the requirement for steam heating of mash at different liquid levels within the pot body 100, thereby eliminating the need to extend the heating time and improving heating efficiency. By providing at least two air inlet valves 310, each inlet 221 is paired with an air inlet valve 310, allowing the inlet 221 to be connected to the steam supply unit 210 via the corresponding air inlet valve 310. Each outlet 222 is connected to the condensate collection unit 230. Therefore, based on the coverage area of ​​the mash within the pot body 100, the opening and closing of the air inlet valves 310 can be controlled to supply steam only to the channels 223 corresponding to the mash coverage area, thus avoiding steam waste. The condensate formed after steam heat exchange is recovered into the condensate collection unit 230 through the outlet 222 corresponding to the channel 223. The beer saccharification apparatus provided in this application embodiment can achieve rational utilization of steam and has high heating efficiency.

[0067] See Figure 1 and Figure 4 In some embodiments, the beer mashing apparatus further includes a control assembly 400, which includes a control element 430, a liquid level detection element 410, and at least two solenoid valves 420. The liquid level detection element 410 is used to detect whether the liquid level of the liquid to be heated in the pot body 100 exceeds any inlet 221. The solenoid valves 420 correspond one-to-one with the air inlet valves 310, and the solenoid valves 420 are connected between the corresponding air inlet valves 310 and the steam supply element 210.

[0068] The liquid level detection element 410 and each solenoid valve 420 are electrically connected to the control element 430. The control element 430 is used to control the solenoid valves 420 corresponding to the first inlet 221 from low to high to the first inlet 221 above the liquid level when the liquid level detection element 410 detects that the liquid level of the liquid to be heated in the pot body 100 exceeds any inlet 221.

[0069] In this way, the control unit 430 automatically controls the opening and closing of the corresponding solenoid valve 420 according to the signal of the liquid level detection unit 410, ensuring that steam only enters the channel 223 corresponding to the area covered by the liquid to be heated, realizing the rational use of steam, improving heating efficiency, and protecting the pot body 100 from dry burning damage; at the same time, it can reduce manual intervention and help improve the stability and reliability of the production process.

[0070] It is understood that the liquid to be heated is mash, and each solenoid valve 420 is normally closed. As mentioned in the previous embodiment, each air intake valve 310 is normally open and can be driven by pneumatic or manual means. In addition, the air intake valve 310 can also be driven by electric means. Considering that the control component 430 usually operates based on low voltage signals, while the air intake valve 310 may require higher operating voltage and current to drive, this embodiment of the application sets the solenoid valve 420 as an intermediate device to achieve electrical isolation and ensure the safe operation of the control component 430.

[0071] For example, the controller 430 may be either a programmable logic controller (PLC) or a distributed control system (DCS).

[0072] Continue reading Figure 4 Furthermore, the control component 400 also includes a temperature detection element 440, which is electrically connected to the control component 430. The temperature detection element 440 is used to detect whether the temperature of the liquid to be heated exceeds a preset value. The control component 430 is used to control each solenoid valve 420 to close when the temperature detection element 440 detects that the temperature of the liquid to be heated exceeds the preset value.

[0073] With this setup, the temperature of the liquid to be heated, i.e. the mash, inside the pot 100 can be monitored in real time by the temperature detection device 440, ensuring that the mash completes the saccharification process within a suitable temperature range, which is beneficial to improving the quality of the final beer.

[0074] Among them, the control unit 430 controls each solenoid valve 420 to close. Each solenoid valve 420 is the solenoid valve 420 corresponding to the first inlet 221 from low to high when the liquid level of the mash in the pot body 100 in the aforementioned embodiment exceeds any inlet 221.

[0075] See Figure 1 In a specific example, the heat exchanger 220 is a spiral heat exchange jacket; each inlet 221 is opened on the first side of the spiral heat exchange jacket facing the pot body 100, each outlet 222 is opened on the second side of the spiral heat exchange jacket facing the pot body 100, and the channel 223 is a spiral channel; wherein the first side and the second side are arranged opposite to each other.

[0076] Specifically, by setting the heat exchange component 220 as a spiral heat exchange clamping belt, the spiral channel provides a continuous and uniform heat exchange path, which helps to increase the contact area between the steam and the outer wall of the pot body 100, improve the heat exchange efficiency, and ensure that heat can be quickly transferred to the mash. Furthermore, the relatively set inlet 221 and outlet 222 help to reduce the resistance in the steam flow, reduce pressure loss, avoid the accumulation of condensate, and improve the overall efficiency of saccharification.

[0077] For example, the first side of the pot body 100 is Figure 1 The first side is to the left of the X direction, and the second side is to the right of the X direction.

[0078] See Figure 2 In some embodiments, the pot body 100 includes a conical portion 110 and a cylindrical portion 120 arranged sequentially along the height direction; one of at least two spiral channels is a variable diameter spiral channel that matches the conical portion 110, and at least one is a constant diameter spiral channel that matches the cylindrical portion 120.

[0079] The conical portion 110 is conical, and the cylindrical portion 120 is cylindrical. As mentioned earlier, at least two inlets 221 and at least two outlets 222 are provided on the spiral heat exchange jacket, and the inlets 221 and outlets 222 correspond one-to-one. The spiral heat exchange jacket forms a spiral channel between any inlet 221 and the corresponding outlet 222 for heat exchange between steam and the periphery of the boiler body 100. Therefore, the spiral heat exchange jacket includes at least two spiral channels.

[0080] It is understandable that by adapting to the shape changes of the matching cone portion 110 through the variable diameter spiral channel and adapting to the uniform geometry of the matching cylinder portion 120 through the equal diameter spiral channel, the spiral heat exchange jacket can better fit the outer wall of the pot body 100, making the heat exchange surface evenly distributed, thereby avoiding the problem of local overheating or uneven heating, which is conducive to improving heat exchange efficiency.

[0081] See Figure 1 In some examples, the beer mashing apparatus also includes a steam branch assembly 500 and a condensate branch assembly 600; the steam branch assembly 500 includes at least two steam branches 510, each corresponding to an inlet 221, and the inlet 221 is connected to a steam supply unit 210 through the corresponding steam branch 510, with an air inlet valve 310 corresponding to each steam branch 510.

[0082] The condensate branch pipe assembly 600 includes at least two condensate branch pipes 610, each corresponding to an outlet 222, and the outlet 222 is connected to the condensate collection component 230 through the corresponding condensate branch pipe 610.

[0083] Specifically, the steam branch pipe assembly 500 makes the steam supply path clearer, facilitates installation and maintenance, and helps reduce maintenance costs and workload; by setting the condensate branch pipe assembly 600, it is ensured that the condensate can be smoothly discharged from the outlet 222, avoiding corrosion and damage to the beer mashing unit by the condensate, and extending its service life.

[0084] For example, both the steam branch pipe 510 and the condensate branch pipe 610 are flexible hoses.

[0085] The design of the hose allows for flexible adjustment of its position according to the actual installation environment, enabling it to bypass obstacles or adapt to irregular spatial layouts, ensuring the smooth installation of the beer mashing unit. The hose also possesses a certain degree of flexibility, which can absorb and buffer the vibrations generated during the operation of the unit, helping to prevent loosening or damage to the connections due to vibration. Furthermore, the flexibility of the hose can effectively disperse stress, avoiding stress concentration caused by temperature changes or mechanical movement, and reducing the risk of branch pipe rupture or leakage.

[0086] Continue reading Figure 1 In some embodiments, the steam supply unit 210 includes a supply unit body 211 and a delivery pump 212, the supply unit body 211 being connected to each steam branch pipe 510 via the delivery pump 212; the condensate collection unit 230 includes a collection unit body 231 and a suction pump 232, the collection unit body 231 being connected to each condensate branch pipe 610 via the suction pump 232.

[0087] The delivery pump 212 can overcome long distances and height differences, ensuring that steam can reach each inlet 221 smoothly and provide each inlet 221 with a relatively stable steam pressure and flow rate; the suction pump 232 can adjust the pumping speed according to actual needs, which is conducive to improving the flexibility of condensate collection, ensuring that condensate can be recovered in a timely manner, and reducing energy consumption.

[0088] The specific types of the delivery pump 212 and the suction pump 232 are not limited in this application embodiment. For example, the delivery pump 212 can be a centrifugal pump or a diaphragm pump, and the suction pump 232 can be a vacuum pump or a screw pump.

[0089] In a specific example, the valve assembly 300 also includes at least two check valves 320, which are respectively installed on the condensate branch pipe 610 so that the condensate flowing out of the outlet 222 flows through the check valves 320 into the condensate collection member 230.

[0090] Thus, the design of the one-way valve 320 can prevent condensate from flowing back from the condensate collection component 230 to the condensate branch pipe 610, avoiding the safety hazards that condensate backflow may pose to the heat exchange component 220 and the condensate branch pipe 610, and thus improving the overall reliability of the device.

[0091] See Figures 1 to 3 In some examples, the beer mashing apparatus also includes an insulation element 700; the insulation element 700 includes a heat-resistant layer 710, an insulation layer 720 and a protective layer 730 that are sequentially fitted together, with the heat-resistant layer 710 covering the outer periphery of the heat exchange element 220.

[0092] Thus, by setting the insulation component 700 as a composite structure of a heat-resistant layer 710, an insulation layer 720, and a protective layer 730 that are nested together in sequence, it is beneficial to reduce heat loss from heat exchange, maintain a stable internal temperature of the pot body 100, and ensure that the mash completes the saccharification process within a suitable temperature range.

[0093] For example, the heat-resistant layer 710 can be made of aluminum silicate fiber felt or ceramic fiber material to avoid deformation or damage caused by temperature; the insulation layer 720 can be made of polyurethane foam material; the protective layer 730 can be made of stainless steel material to provide external protection for the insulation layer 720, prevent physical damage and environmental corrosion, and at the same time have waterproof and dustproof functions to ensure that the insulation effect is not affected by external factors.

[0094] During the saccharification process, to ensure the mash is mixed evenly, please refer to... Figure 2 In some embodiments, the beer mashing apparatus further includes a stirring assembly 800, which includes a drive member 810 and a stirring member 820. The stirring member 820 includes a connecting portion 821 and at least two stirring parts 822 connected to the connecting portion 821. The drive member 810 is connected to the connecting portion 821. The stirring parts 822 and part of the connecting portion 821 are placed inside the pot body 100. The drive member 810 is used to drive the connecting portion 821 to rotate each stirring part 822.

[0095] The drive unit 810 can flexibly adjust the stirring speed according to actual needs, so that the stirring part 822 can fully stir the mash in the pot body 100, avoid uneven mixing in some areas, and help improve the quality of the final beer.

[0096] In a specific implementation, the driving component 810 can be a motor, and the connecting part 821 is a stirring shaft coaxially connected to the driving shaft of the motor; the stirring part 822 can adopt the structure in the prior art, such as setting the stirring part 822 as a large blade stirring paddle, and the stirring paddle blade is provided with multiple anti-vacuum and vortex material passage holes.

[0097] For example, the stirring section 822 can be configured as two or more, and the embodiments of this application do not limit this.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
