Description

Technical Field

[0001] The invention relates to the field of mixers, in particular to a novel mixer for beer brewing. Background Art

[0002] In the beer brewing process, stirring is an important link, which mainly involves the following aspects of stirring: 1. Wet stirring before malt crushing; 2. Stirring during saccharification; 3. Stirring before wort boiling; 4. Stirring during beer fermentation. Among them, wet stirring before malt crushing is to stir the barley malt evenly with 3%-5% tap water before malt crushing. This step helps to better crush the malt and improve the efficiency of subsequent saccharification.

[0003] In the beer brewing process, the wet stirring before malt crushing is a key step, which directly affects the efficiency of subsequent saccharification and the quality of beer. For this stirring process, the most important thing to pay attention to is moisture control. As mentioned earlier, it is usually necessary to use 3%-5% tap water to stir the barley malt evenly. This ratio is determined based on the water content of the malt and the required saccharification efficiency. Too much water will cause the malt to be too wet, making it difficult to crush, and may affect the enzyme activity during the saccharification process; too little water will not be able to fully wet the malt, which will also affect the crushing effect and saccharification efficiency. When stirring, make sure that each grain of malt is evenly moistened with water.

[0004] However, the existing mixer has certain defects in the wet stirring of malt before crushing. There is more water at the bottom of the mixing container, so that the malt at the bottom is over-wetted by water, while the malt at the top is not wetted enough, which leads to uneven wetting of the malt. Therefore, those skilled in the art provide a new mixer for beer brewing to solve the problems raised in the above background technology. Summary of the invention

[0011] As a further solution of the present invention: the outer side surface of the positioning pin is fixedly connected to two anti-slip rings arranged in parallel up and down, one of the anti-slip rings is located below the support seat, and the other anti-slip ring is located above the support seat.

[0012] As a further solution of the present invention: bearings are embedded between the rotating shaft and both side walls of the rectangular frame.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The angle adjustment mechanism of the present application can flip the mixing tank as needed, so that the malt at the top and bottom of the mixing chamber can be fully moistened, the uniformity of malt moistening can be improved, and it is convenient to use. In addition, the angle adjustment mechanism can also adjust the inclination angle of the mixing tank as needed, so that the malt at each position in the mixing chamber can be fully moistened, and the uniformity of mixing can be improved.

[0020] 2. During the rotation of the stirring shaft, the adaptive beating mechanism of the present application stirs and breaks up the malt in the stirring chamber by swinging the conical spring, thereby effectively preventing the malt from clumping together. In addition, the adaptive beating mechanism can also be used in conjunction with an angle adjustment mechanism. After the stirring tank is flipped one hundred and eighty degrees, the conical spring flips to the top, and as the stirring shaft continues to rotate, the conical spring slowly descends along the optical axis under the action of gravity. The conical guide seat not only provides a load for the conical spring to increase the descending power, but also reduces the descending resistance by utilizing the conical shape. By repeatedly flipping the stirring tank, the conical spring can break up and stir the malt at different heights from top to bottom, thereby improving the uniformity of mixing.

[0021] 3. After the malt is mixed, it needs to be collected in a container. When the staff sends the container to the bottom of the mixing tank, if they are not careful, it will collide with the bottom frame, thereby affecting the stability of the entire mixer. For this reason, the present application sets up a stability buffer mechanism, which not only adds two reinforcing rods on the bottom frame, but also sets a buffer cloth between the two reinforcing rods to buffer the impact of the container, thereby effectively buffering the delivery of the container and improving the overall stability of the mixer.

[0022] 4. Compared with the traditional feed port and discharge port, the present application combines the two into one, and with the angle adjustment mechanism, the mixing tank can be flipped. The feed port can not only be used for feeding but also for unloading. The structure is simple and the workload of the staff for cleaning the feed port is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] As mentioned in the background technology of this application, research has found that the existing mixers have certain defects in the wet stirring of malt before crushing. There is more water at the bottom of the mixing container, which makes the bottom malt over-moistened with water, while the top malt is not moistened, resulting in uneven wetting of the malt.

[0035] In order to solve the above-mentioned defects, the present application discloses a novel mixer for beer brewing, which can fully moisten the malt at the top and bottom of the stirring chamber 17, improve the uniformity of malt moistening, and facilitate use.

[0036] The following will describe in detail how the solution of the present application solves the above technical problems in conjunction with the accompanying drawings.

[0037] See also Figures 1 to 9 In an embodiment of the present invention, a new type of mixer for beer brewing includes a base frame 1, tripods 2 are fixedly connected to both sides of the top surface of the base frame 1, a stirring tank 3 is movably connected between the two tripods 2, and an angle adjustment mechanism is provided between the stirring tank 3 and the tripod 2, and a stabilization buffer mechanism is fixedly connected to the inner side of the base frame 1; a stirring chamber 17 is provided inside the stirring tank 3, and a driving motor 13 is fixedly connected to the top of the stirring tank 3, the bottom output shaft of the driving motor 13 passes through the stirring tank 3 and extends to the inside of the stirring chamber 17 and is fixedly connected to a stirring shaft 18, and four scraping stirring mechanisms and four adaptive beating mechanisms are provided on the outer side of the stirring shaft 18, and the scraping stirring mechanisms and the adaptive beating mechanisms are alternately and evenly distributed. The angle adjustment mechanism provided in the present application can flip the stirring tank 3 or adjust the angle as needed, so that the malt at the top and bottom of the stirring chamber 17 can be fully moistened, the uniformity of malt wetting is improved, and it is easy to use.

[0038] In this embodiment, the adaptive feeding mechanism specifically includes: two strip-shaped horizontal plates 19 fixed in parallel up and down on the outer side of the stirring shaft 18, two parallel optical axes 20 are fixedly connected between the two strip-shaped horizontal plates 19, each optical axis 20 is externally sleeved with a movable conical spring 21, and conical guide seats 22 are symmetrically fixedly connected at both ends of the conical spring 21, and an axial hole 23 is opened inside the conical guide seat 22 for the optical axis 20 to pass through. During the rotation of the stirring shaft 18, the adaptive beating mechanism of the present application stirs and breaks up the malt in the stirring chamber 17 by swinging the conical spring 21, thereby effectively preventing the malt from clumping together. In addition, the adaptive beating mechanism can also be used in conjunction with an angle adjustment mechanism. After the stirring tank 3 is flipped one hundred and eighty degrees, the conical spring 21 flips to the top. As the stirring shaft 18 continues to rotate, the conical spring 21 slowly descends along the optical axis 20 under the action of gravity. The conical guide seat 22 not only provides a load for the conical spring 21 to increase the descending power, but also reduces the descending resistance by utilizing the conical shape. By repeatedly flipping the stirring tank 3, the conical spring 21 can break up and stir the malt at different heights from top to bottom, thereby improving the uniformity of mixing.

[0039] In this embodiment, the angle adjustment mechanism specifically includes: a rectangular frame 4 fixed on the top of the tripod 2, a rotating shaft 5 is provided inside the rectangular frame 4, and a connecting block 6 is fixedly connected between one end of the rotating shaft 5 and the mixing tank 3, and a handle 7 is fixedly connected to the other end of the rotating shaft 5, a support seat 9 is fixedly connected to the top of one side of the rectangular frame 4 away from the mixing tank 3, and a positioning pin 10 is provided inside the supporting seat 9, and a plurality of evenly distributed positioning holes 12 are provided on the outer surface of the rotating shaft 5 below the positioning pin 10, and the positioning holes 12 match the positioning pin 10. The angle adjustment mechanism can not only flip the mixing tank 3, but also adjust the tilt angle of the mixing tank 3 as needed, so that the malt at each position in the mixing chamber 17 can be fully moistened, thereby improving the uniformity of mixing.

[0040] In this embodiment, two anti-slip rings 11 are fixedly connected to the outer side of the positioning pin 10, one anti-slip ring 11 is located below the support seat 9, and the other anti-slip ring 11 is located above the support seat 9. The provision of the anti-slip ring 11 can effectively prevent the positioning pin 10 from detaching from the support seat 9.

[0041] In this embodiment, bearings 8 are embedded between the rotating shaft 5 and the two side walls of the rectangular frame 4. The arrangement of the bearings 8 can effectively reduce the friction resistance between the rotating shaft 5 and the rectangular frame 4.

[0042] In this embodiment, the scraping stirring mechanism specifically includes: a strip-shaped fan-shaped shovel plate 24 located in the stirring chamber 17 and in contact with the inner wall of the stirring chamber 17, and three parallel connecting rods 25 are fixedly connected between the inner side surface of the strip-shaped fan-shaped shovel plate 24 and the rotating shaft 5. The scraping stirring mechanism provided in the present application can scrape off the malt attached to the inner wall of the stirring chamber 17 during the stirring process, so as to prevent some malt from being attached to the inner wall of the stirring chamber 17 and not being fully wetted.

[0043] In this embodiment, the stabilization buffer mechanism specifically includes: two reinforcing rods 26 symmetrically fixed on the inner side of the base frame 1, a rotating cavity 27 is provided inside the reinforcing rods 26, and a reel 28 is rotatably connected inside the rotating cavity 27, a cavity 29 connected to the corresponding rotating cavity 27 is provided on the opposite surface of the two reinforcing rods 26, a buffer cloth 30 is provided between the two cavities 29, and the two ends of the buffer cloth 30 respectively penetrate the two cavities 29 and are wound on the reel 28 in the corresponding rotating cavity 27, and elastic recovery parts are provided above and below the rotating cavity 27. After the malt is mixed, a container is needed to collect the material, and when the staff sends the container to the bottom of the mixing tank 3, if they are not careful, it will collide with the base frame 1, thereby affecting the stability of the entire mixer. For this reason, the present application not only adds two reinforcing rods 26 to the base frame 1 through the stabilization buffer mechanism, but also sets a buffer cloth 30 between the two reinforcing rods 26 that can buffer the impact of the container, thereby effectively buffering the delivery of the container and improving the overall stability of the mixer.

[0044] In this embodiment, the elastic restoring member specifically includes: circular cavities 31 opened above and below the rotating cavity 27, the two ends of the scroll 28 respectively penetrate the two circular cavities 31, and the scroll 28 in the circular cavity 31 is sleeved with a spiral spring 32, one end of the spiral spring 32 is fixedly connected to the scroll 28, and the other end of the spiral spring 32 is fixedly connected to the inner wall of the circular cavity 31. The setting of the elastic restoring member can use the elastic potential energy accumulated by the spiral spring 32 to restore the buffer cloth 30 to the initial position after the container is taken away after receiving the malt, so as to facilitate the next material receiving buffer.

[0045] In this embodiment, the bottom end of the mixing tank 3 is fixedly connected with a feed inlet and a discharge port 14, and the internal thread of the feed inlet and a discharge port 14 is connected with a plug 15. Compared with the traditional feed inlet and discharge port, the present application combines the two into one, and cooperates with the angle adjustment mechanism to turn the mixing tank 3 over, which can not only feed but also discharge, and has a simple structure, while reducing the workload of the staff to clean the feed port.

[0046] In this embodiment, strip-shaped observation windows 16 are symmetrically embedded on both sides of the mixing tank 3, and the strip-shaped observation windows 16 match the mixing chamber 17. The strip-shaped observation windows 16 are convenient for the staff to view the mixing progress of the malt in real time, and convenient for the staff to turn over the mixing tank 3 at the appropriate time.

[0047] The working principle of the present invention is: when in use, first, the mixing tank 3 is turned over one hundred and eighty degrees through the angle adjustment mechanism, specifically, the positioning pin 10 is twisted so that the positioning pin 10 is disengaged from the positioning hole 12 of the lower rotating shaft 5, and then the rotating shaft 5 is rotated by the handle 7. Since a connecting block 6 is fixedly connected between one end of the rotating shaft 5 and the mixing tank 3, the mixing tank 3 rotates with the rotating shaft 5. After the mixing tank 3 rotates one hundred and eighty degrees, the positioning pin 10 is twisted in the opposite direction so that the positioning pin 10 is inserted into the positioning hole 12 corresponding to the lower rotating shaft 5. At this time, the position of the mixing tank 3 is fixed, and the inlet and outlet 14 of the mixing tank 3 faces upward.

[0048] Then, the plug 15 in the inlet and outlet 14 is screwed out, and the staff sends the malt to be stirred into the stirring chamber 17 from the inlet and outlet 14. After all the malt is sent in, the plug 15 is screwed into the inlet and outlet 14. Then, the driving motor 13 is operated to drive the stirring shaft 18 to rotate, and the adaptive material-beating mechanism stirs and breaks up the malt in the stirring chamber 17 through the swing of the conical spring 21 during the rotation of the stirring shaft 18, effectively preventing the malt from clumping together. In addition, the strip-shaped fan-shaped shovel plate 24 of the scraping stirring mechanism can scrape off the malt attached to the inner wall of the stirring chamber 17 during the stirring process, so as to prevent some malt from being attached to the inner wall of the stirring chamber 17 and not being fully wetted, and the connecting rod 25 between the strip-shaped fan-shaped shovel plate 24 and the rotating shaft 5 can also play a stirring role.

[0049] After stirring for a period of time, the staff member turns the mixing tank 3 over 180 degrees again through the angle adjustment mechanism. At this time, the conical spring 21 turns over to the top. As the mixing shaft 18 continues to rotate, the conical spring 21 slowly descends along the optical axis 20 under the action of gravity. Among them, the conical guide seat 22 not only provides a load for the conical spring 21 to increase the downward power, but also reduces the downward resistance by using the cone shape. By repeatedly turning over the mixing tank 3, the conical spring 21 can break up and stir the malts at different heights from top to bottom, thereby improving the uniformity of mixing. It should be noted that the angle adjustment mechanism can not only turn over the mixing tank 3, but also adjust the inclination angle of the mixing tank 3 as needed. It only needs to adjust the mixing tank 3 to a suitable inclination angle, and then insert the positioning pin 10 into the corresponding positioning hole 12 to fix the position of the mixing tank 3, so that the malts at various positions in the mixing chamber 17 can be fully moistened, thereby improving the uniformity of mixing.

[0050] After the malt is mixed, it needs to be collected in a container. When the staff sends the container to the bottom of the mixing tank 3, if they are not careful, it will collide with the base frame 1, thereby affecting the stability of the entire mixer. For this reason, the present application sets up a stabilizing buffer mechanism, not only adding two reinforcing rods 26 to the base frame 1, but also setting a buffer cloth 30 between the two reinforcing rods 26 that can buffer the impact of the container, thereby effectively buffering the delivery of the container and improving the overall stability of the mixer. The specific working process of the stabilizing buffer mechanism is as follows: when the container for receiving malt is sent to the inlet and outlet 14, the container first contacts the buffer cloth 30, and as the container is further fed in, the buffer cloth 30 is pushed to move backwards. During the process, the reel 28 in the rotating cavity 27 rotates to release the buffer cloth 30, and the released buffer cloth 30 is sent out from the cavity 29. In the process of the buffer cloth 30 being pushed to move backwards, the impact of the container can be buffered. In addition, in the process of the reel 28 rotating to release the buffer cloth 30, the vortex spring 32 in the circular cavity 31 is deformed to accumulate elastic potential energy. After the container receives the malt and is taken away, the elastic potential accumulated by the vortex spring 32 drives the reel 28 to flip and reel in the buffer cloth 30, and then restores the buffer cloth 30 to its initial position to facilitate the next material receiving buffer. It should be noted that when the malt is mixed and collected, the inlet and outlet 14 is adjusted to face downward. Compared with the traditional inlet and outlet, the present application combines the two into one, and the mixing tank 3 can be turned over with the angle adjustment mechanism. The inlet and outlet 14 can be used not only for feeding but also for unloading. It has a simple structure and reduces the workload of the staff in cleaning the feed port.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
