[0035] An embodiment of the present application provides a wort preparation system 10 , which can be applied in the field of beer production and has functions such as malt saccharification, wort filtration, and wort boiling.

[0036] like Figure 1 As shown, the wort preparation system 10 includes a tank 100, a heating component 200, a filtering component 300 and a reflux component 400. Figure 1 As shown, the top of the tank body 100 is provided with an openable and closable top cover 110 to facilitate the placement of malt raw materials and a certain amount of saccharification water and the installation of the filtering assembly 300.

[0037] Among them, such as Figure 1 As shown, the top cover 110 is provided with a first observation mirror 111, through which the filtering and boiling conditions of the wort can be observed. Figure 1 The top cover 110 may also be provided with an exhaust hole 112, which can prevent the tank body 100 from being damaged due to excessive air pressure.

[0038] The heating assembly 200 is disposed at the bottom of the tank body 100 and is used to heat the inner cavity of the tank body 100. The heating assembly 200 can heat the malt to achieve malt saccharification, and can also heat and boil the wort after malt saccharification. Optionally, the heating assembly 200 can be an electric heating wire.

[0039] In order to ensure the heating effect of the heating component 200 on the malt or wort, Figure 1As shown, in one embodiment, the wort preparation system 10 may further include an insulation layer 800, which is coated on the wall of the tank body 100. The insulation layer 800 may be made of a fiber-based insulation material such as rock wool, glass wool, or composite silicate. The insulation layer 800 may be coated on at least one of the inner or outer walls of the tank body 100. Alternatively, the insulation layer 800 may be provided on the outer wall of the tank body 100 to prevent the insulation layer 800 from falling off and contaminating the malt or wort within the tank body 100.

[0040] The filter assembly 300 can be disposed within the tank body 100 to divide the interior of the tank body 100 from top to bottom into a first chamber A and a second chamber B. The filter assembly 300 is not fixed to the tank body 100 in a non-detachable manner, allowing it to be installed within the tank body 100 after malt saccharification to filter the malt mash (including wort and spent grains) after malt saccharification, allowing the wort to flow into the second chamber B of the tank body 100, while the spent grains are retained by the filter assembly 300. After filtration is completed, the filter assembly 300 can also be removed from the tank body 100, thereby removing the spent grains from the tank body 100.

[0041] The reflux assembly 400 has a first state and a second state. In the first state, it is used to connect the first chamber A with the second chamber B. In the second state, it is used to connect the second chamber B with the outside of the tank body 100. When preparing wort, the top cover 110 of the tank body 100 is first opened, malt raw materials and a certain amount of saccharification water are placed into the second chamber B of the tank body 100, and the filtering assembly 300 is installed in the tank body 100. Then, the heating assembly 200 heats the malt mash (i.e., a mixture of the malt raw materials and the saccharification water) to saccharify the malt. After the heating assembly 200 completes saccharification of the malt, the reflux assembly 400 is adjusted to the first state, and the saccharified malt mash flows back from the second chamber B to the first chamber A through the reflux assembly 400. After being filtered by the filtering assembly 300, the wort in the malt mash flows into the second chamber B, and the heating assembly 200 heats the wort to boil it. After the wort is boiled, the reflux assembly 400 is adjusted to the second state, and the boiled wort flows out of the tank body 100 through the reflux assembly 400 and is collected for subsequent use.

[0042] Among them, when the malt is first heated in the second chamber B of the tank body 100 for saccharification, in order to ensure the saccharification effect of the malt, as shown in FIG. Figure 1 As shown, the wort preparation system 10 may further include a temperature sensor 900, which is disposed on the tank body 100 and is used to obtain the temperature of the second chamber B. During malt mashing, the temperature of the second chamber B can be detected in real time by the temperature sensor 900, and the temperature of the second chamber B can be adjusted in a timely manner to ensure that the malt is at an appropriate temperature and avoid excessive temperature.

[0043] When the wort is heated and boiled in the second chamber B of the tank 100, auxiliary materials such as hops can be added to the wort to improve the taste of the beer. Figure 1 As shown, in one embodiment, the second chamber B is provided with an openable and closable auxiliary material adding port 130. It can be understood that the auxiliary material adding port 130 is closed under normal circumstances and is opened only when the auxiliary material is added to the wort.

[0044] In order to facilitate the malt mash and the boiled wort in the second chamber B to flow smoothly into the reflux pipe 410, the bottom of the tank body 100 is tilted, which can guide the flow of the malt mash and the boiled wort in the second chamber B.

[0045] The wort preparation system 10 is configured such that a heating component 200, a filtering component 300, and a reflux component 400 are provided on the tank body 100. The malt is first heated in the second chamber B of the tank body 100 for saccharification, and then refluxes to the first chamber A of the tank body 100 through the reflux component 400. Thereafter, the malt is filtered by the filtering component 300 and flows again into the second chamber B of the tank body 100 for heating and boiling. This enables the wort preparation system 10 to integrate the three functions of malt saccharification, wort filtering, and wort boiling, thereby simplifying the structure of the wort preparation system 10 and reducing the space occupied by the wort preparation system 10.

[0046] like Figure 1 As shown, in one embodiment, the reflux assembly 400 includes a reflux pipe 410, a discharge pipe 420 and a power pump 430. The reflux pipe 410 is connected to the first chamber A and the second chamber B. The power pump 430 and the discharge pipe 420 are both arranged on the reflux pipe 410, and the power pump 430 is located upstream of the discharge pipe 420; the reflux pipe 410 is provided with a first control valve 411, and the discharge pipe 420 is provided with a second control valve 421. In the first state, the first control valve 411 is open and the second control valve 421 is closed. In the second state, the first control valve 411 is closed and the second control valve 421 is opened. After the heating component 200 completes saccharification of the malt, the power pump 430 and the first control valve 411 are opened, and the second control valve 421 is closed. The malt mash (i.e., wort and spent grains) after saccharification of the malt then flows back from the second chamber B to the first chamber A through the reflux component 400. After the wort is heated and boiled by the heating component 200, the power pump 430 and the second control valve 421 are opened, and the first control valve 411 is closed. The boiled wort then flows out of the tank body 100 through the discharge pipe 420.

[0047] Optionally, the first control valve 411 and the second control valve 421 may be manual valves, solenoid valves, electric valves or pneumatic valves.

[0048] Alternatively, as Figure 1As shown, the return pipe 410 is provided with a second observation mirror 412, which is located downstream of the first control valve 411. The second observation mirror 412 is used to observe whether the filtered wort is clear. If it is clear, the power pump 430 and the first control valve 411 are closed to stop the backflow of the wort. The clarified wort then flows through the filtration assembly 300 into the second chamber B for subsequent boiling. If it is not clear, the power pump 430 and the first control valve 411 remain open, and the second control valve 421 is closed to allow the wort to flow back and be filtered.

[0049] In one embodiment, if Figure 1 As shown, the reflux assembly 400 further includes a filter 440, which is disposed on the discharge pipe 420 and downstream of the second control valve 421. The filter 440 can filter the boiled wort to prevent hops, heat coagulants and other residues in the wort from flowing out, thereby obtaining clarified wort.

[0050] In one embodiment, if Figure 1 As shown, the reflux assembly 400 further includes a drain pipe 450, which is connected to the reflux pipe 410 and is equipped with a third control valve 451. After the boiled wort is discharged, the tank body 100 can be cleaned to ensure its cleanliness; thereafter, the third control valve 451 is opened, and the cleaned wastewater can be discharged through the drain pipe 450. The drain pipe 450 is positioned on the reflux pipe 410, rather than at the bottom of the tank body 100, so that the tank wall of the tank body 100 is covered with the insulation layer 800 as much as possible, ensuring the insulation effect of the insulation layer 800 on the tank body 100. Of course, in other embodiments, the drain pipe 450 can also be positioned at the bottom of the tank body 100.

[0051] Optionally, the third control valve 451 may be a manual valve, a solenoid valve, an electric valve or a pneumatic valve.

[0052] like Figure 1 As shown, in some embodiments of the present application, the inner cavity of the tank body 100 is provided with a mounting portion 120 along its circumference; Figure 1 and Figure 2As shown, the filter assembly 300 includes a mounting barrel 310 and a filter screen 320. The filter screen 320 is located at the bottom of the mounting barrel 310 and can overlap the mounting portion 120. After malt saccharification is completed, the filter assembly 300 can be directly placed in the mounting portion 120 within the tank body 100, facilitating assembly and disassembly of the filter assembly 300. The mounting barrel 310 is positioned above the filter screen 320, allowing all malt saccharified mash to pass through the filter screen 320 and enter the second chamber B of the tank body 100. This prevents the malt saccharified mash from flowing into the second chamber B of the tank body 100 through the gap between the filter screen 320 and the mounting portion 120 without being filtered by the filter screen 320. It should be noted that the mounting barrel 310 is located near the inner wall of the tank body 100, and the downstream end of the reflux pipe 410 extends into the mounting barrel 310.

[0053] Optionally, the mounting cylinder 310 may be connected to the filter screen 320 by welding or integral molding.

[0054] The mounting portions 120 in the can body 100 may be provided in a circle along the circumference of the can body 100 , or may be provided in plurality at intervals along the circumference.

[0055] Furthermore, if Figure 2 As shown, in one embodiment, the filter assembly 300 further includes a handle 330, which is disposed on the top of the mounting cylinder 310. An operator can hold the handle 330 of the filter assembly 300 to place the filter assembly 300 on the mounting portion 120 in the tank body 100 or remove the filter assembly 300 from the tank body 100, thereby facilitating assembly and disassembly of the filter assembly 300.

[0056] The handle 330 can be configured as an inverted "U" shape. The handle 330 can be welded or integrally formed to the top of the mounting tube 310. Two handles 330 can be provided radially spaced apart along the mounting tube 310, with the operator's two hands each holding one handle 330 for ease of operation.

[0057] like Figure 1 and Figure 3As shown, in some embodiments of the present application, the wort preparation system 10 further includes a first stirring member 500, which includes a first motor 510 and a first stirring head 520. The first motor 510 can be mounted on the top cover 110, and the first stirring head 520 is coupled to the output shaft of the first motor 510 and can extend into the first chamber A. Before malt saccharification, the top cover of the tank body 100 is opened, malt and saccharification water are added to the tank body 100, and the filtration assembly 300 is placed in the tank body 100. The first stirring member 500 is then mounted on the top cover 110 of the tank body 100, and finally, the top cover 110 is mounted on the tank body 100. When the filtration assembly 300 filters the malt mash after malt saccharification, the first motor 510 is turned on, and the first stirring head 520 stirs the malt mash after malt saccharification, accelerating the filtration of the malt mash by the filtration assembly 300.

[0058] Alternatively, as Figure 3 As shown, the first stirring member 520 may include a first rotating shaft 521, a mounting rod 522, and a plurality of plowing blades 523 disposed below the mounting rod 522. The plowing blades 523 are provided with a plurality of plowing blades along their axial direction. This structure of the first stirring member 500 can effectively loosen the wheat trough in the malt mash, improving the filtering effect of the wort.

[0059] The top cover 110 has a first opening for allowing the first rotating shaft 521 to pass through, wherein a first sealing ring is provided on the inner wall of the first opening, and the first sealing ring is used to seal the gap between the first rotating shaft 521 and the inner wall of the first opening, thereby preventing the malt mash in the first chamber A from overflowing from the first opening of the top cover 110.

[0060] like Figure 1 and Figure 4 As shown, in some embodiments of the present application, the wort preparation system 10 further includes a second stirring member 600, which includes a second motor 610 and a second stirring head 620. The second motor 610 is disposed at the bottom of the tank body 100, and the second stirring head 620 is coupled to the output shaft of the second motor 610 and extends into the second chamber B. When malting, the second motor 610 is turned on, and the second stirring head 620 stirs the malt, thereby evenly heating the malt and accelerating the saccharification process. When boiling the wort, the second motor 610 is turned on, and the second stirring head 620 stirs the wort, thereby evenly heating the wort and accelerating the boiling process.

[0061] Optionally, the second stirring head 620 can be as follows Figure 4 As shown, it includes a second rotating shaft 621 connected to the output shaft of the second motor 610 and a blade 622 connected to the second rotating shaft 621, wherein the blade 622 is generally in a "V" shape.

[0062] The bottom of the tank body 100 has a second opening for the second rotating shaft 621 to pass through, wherein a second sealing ring is provided on the inner wall of the second opening, and the second sealing ring is used to seal the gap between the second rotating shaft 621 and the inner wall of the second opening, thereby preventing the malt mash or wort in the second chamber B from overflowing from the second opening of the tank body 100.

[0063] like Figure 1 As shown, in some embodiments of the present application, the wort preparation system 10 further includes a support leg 700, which is used to support the tank body 100. The support leg 700 can support the tank body 100 on the operating platform.

[0064] The number of the legs 700 can be set according to the requirements, for example, four legs 700 are arranged in a matrix, wherein a reinforcement rod 720 is provided between two adjacent legs 700 (see Figure 1 ).

[0065] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
