Description

Technical Field

[0001] The invention relates to the technical field of saccharification pots, in particular to a mixing device used for beer production. Background Art

[0002] Beer production is a complex process, including malt preparation, saccharification, fermentation, maturation and packaging. As a key link, the saccharification stage directly affects the quality and flavor of beer. The saccharification process involves converting the starch in the malt into sugars required for fermentation. The key to this process is to use a saccharification pot to mix and heat the malt and water so that the enzymes in the malt can break down the starch into fermentable sugars.

[0003] At present, the patent with the patent authorization announcement number CN213078205U discloses a saccharification pot with a stirring device, including a pot body, a stirring mechanism is arranged in the pot body, and a plurality of turbulence plates are vertically arranged on the inner wall of the pot body, and the plurality of turbulence plates are evenly arranged along the circumferential direction of the pot body. By setting the turbulence plates, a certain turbulence can be formed after the mixed liquid hits the baffle, and the movement law of the mixed liquid is destroyed through the action of the turbulence, so that the components of the mixed liquid have a strong relative movement, thereby improving the mixing and stirring effect.

[0004] Although the saccharification pot in the above patent can improve the mixing and stirring effect, it still has certain defects: in order to ensure the hygiene of the equipment, avoid cross-contamination between different batches, and ensure the quality of the next batch of malt produced, the saccharification pot needs to be cleaned after each production is completed. Since the space inside the saccharification pot is large, the saccharification pot is cleaned by flushing. However, during the flushing process, the contact time between the cleaning liquid and the equipment is relatively short, and part of the cleaning liquid will be directly lost and difficult to be effectively utilized. In order to achieve the desired cleaning effect, it is necessary to increase the amount of cleaning agent, which can easily cause waste. Summary of the invention

[0018] 3. This mixing device used for beer production protects and limits the thread groove of the stirring shaft through a protective accordion pipe to prevent malt from sticking to the thread groove and causing difficulty in cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figures 1 to 9 A mixing device for beer production includes a saccharification pot body 1, a stirring motor 2 is fixedly connected to the top of the saccharification pot body 1, a stirring shaft 3 is rotatably connected to the middle position of the saccharification pot body 1, the top of the stirring shaft 3 is fixedly connected to the output end of the stirring motor 2, stirring blades 5 are fixedly connected to both sides of the lower end of the stirring shaft 3, a threaded ring 10 is threadedly connected to the middle position of the stirring shaft 3, and a plurality of cavities 13 are provided on the outer wall of the threaded ring 10, an upper end connecting block 16 is fixedly connected to the top of the inner side of the saccharification pot body 1, an air vent is provided on the top of the upper end connecting block 16, and a bottom of the upper end connecting block 16 is provided with a vent hole. The inner ring and the outer ring are both fixedly connected with a sleeve 20, the bottom of the sleeve 20 is fixedly connected with a connecting sleeve organ pipe 21, the bottom of the connecting sleeve organ pipe 21 is fixedly connected with a lower end connecting block 22, the inner side of the upper end of the upper end connecting block 16 is provided with a liquid inlet groove 18, the top of the saccharification pot body 1 is fixedly connected with a connecting pipe 17 matching the liquid inlet groove 18, the inner and outer sides of the upper end connecting block 16 are provided with liquid outlet grooves 19, the liquid outlet groove 19 is connected with the liquid inlet groove 18, and both sides of the lower end of the lower end connecting block 22 are provided with fixed linear motors 28, and the middle position of the linear motor 28 is connected with a motor shaft 29.

[0031] The mixing device for beer production in the present invention, when the saccharification pot body 1 is cleaned, the linear motor 28 is started first, and the motor shaft 29 is driven by the linear motor 28 to move, so that the motor shaft 29 is inserted into the cavity 13, and then the stirring motor 2 is started, and the stirring motor 2 drives the stirring shaft 3 to rotate. Since the threaded ring 10 is threadedly connected with the stirring shaft 3 and the threaded ring 10 is restricted by the motor shaft 29, the threaded ring 10 will move downward, thereby driving the lower end connecting block 22 to move downward, so that the connecting sleeve accordion pipe 21 is unfolded, and after unfolding, the linear motor 28 is started again to move away from the stirring shaft 3, so that the motor shaft 29 is separated from the cavity 13, and then the cleaning agent is injected into the liquid inlet tank 18 through the connecting pipe 17, and the cleaning agent will enter the saccharification pot body 1 through the liquid outlet tank 19 until the saccharification pot is cleaned. The main body 1 is filled, so that the cleaning agent can be in contact with impurities for a longer and more complete time, which facilitates the reaction of the cleaning agent with the dirt on the inner wall of the saccharification pot main body 1, thereby improving the cleaning effect. After the cleaning is completed, the linear motor 28 can be started again to insert the motor shaft 29 into the cavity 13, and then the stirring motor 2 is started and rotated in the opposite direction. In this way, the threaded ring 10 threadedly connected to the stirring shaft 3 can be moved upward, and then the lower end connecting block 22 can be moved to the upper end of the saccharification pot main body 1, so that the saccharification pot main body 1 can continue production activities. In addition, the structure of the saccharification pot main body 1 in the present invention is similar to a saccharification pot structure with a stirring device disclosed in the patent authorization announcement number CN213078205U, so it will not be elaborated here.

[0032] As a preferred technical solution of the present invention, limiting blocks 26 are fixedly connected to both sides of the inner wall of the saccharification pot main body 1, and clamping blocks 24 are fixedly connected to both sides of the lower end connecting block 22. The end of the clamping block 24 is U-shaped, and the clamping block 24 matches the limiting block 26.

[0033] Specifically, the lower end connecting block 22 is restricted by the clamping block 24 to prevent the lower end connecting block 22 from rotating together with the threaded ring 10 .

[0034] As a preferred technical solution of the present invention, a socket 25 is provided at the lower end of the clamping block 24, and slots 27 are provided at the upper and lower ends of the limit block 26. The socket 25 and the slot 27 are matched with the motor shaft 29, and a chamfer is provided at the end of the motor shaft 29 away from the stirring shaft 3.

[0035] Specifically, when the lower connecting block 22 moves to the upper or lower end of the saccharification pot main body 1, the linear motor 28 will drive the motor shaft 29 to move in the direction away from the stirring shaft 3. At the same time, the end of the motor shaft 29 away from the stirring shaft 3 will be inserted into the slot 27 through the socket 25, thereby restricting the block 24. In this way, the lower connecting block 22 can be restricted and fixed to prevent the lower connecting block 22 from moving downward by itself due to weight reasons.

[0036] As a preferred technical solution of the present invention, a receiving groove 30 is provided at one end of the motor shaft 29 close to the threaded ring 10, and an extrusion block 32 is slidably connected to one end of the receiving groove 30. An extrusion elastic member 31 is provided inside the receiving groove 30, and one end of the extrusion elastic member 31 is fixedly connected to the end of the receiving groove 30, and the other end of the extrusion elastic member 31 is fixedly connected to the extrusion block 32.

[0037] Specifically, when the motor shaft 29 moves toward the stirring shaft 3, if there is an error in the stopping position of the stirring shaft 3 during rotation, resulting in the extrusion block 32 not being aligned with the cavity 13, then when the motor shaft 29 moves toward the threaded ring 10, the extrusion block 32 will abut against the outer wall of the threaded ring 10. In this way, when the stirring shaft 3 rotates, since the threaded ring 10 is not restricted, it will rotate with the stirring shaft 3 until the extrusion block 32 is aligned with the cavity 13. Then the extrusion elastic member 31 will push the extrusion block 32 so that the extrusion block 32 is inserted into the cavity 13, thereby restricting the threaded ring 10. Subsequently, the threaded ring 10 will mobilize the lower end connecting block 22 to move.

[0038] As a preferred technical solution of the present invention, the side of the extrusion block 32 close to the threaded ring 10 is rotatably connected with a roller 33. The rolling friction of the roller 33 replaces the sliding friction between the extrusion block 32 and the threaded ring 10, thereby reducing the probability of damage to the extrusion block 32 and the threaded ring 10.

[0039] As a preferred technical solution of the present invention, a push plate 15 is slidably connected to the side of the cavity 13 away from the stirring shaft 3, and an outward push elastic member 14 is fixedly connected to the side of the push plate 15 close to the stirring shaft 3, and the other end of the outward push elastic member 14 is fixedly connected to the inner wall of the cavity 13.

[0040] Specifically, when the motor shaft 29 is not inserted into the cavity 13, the outward-pushing elastic member 14 will push the push plate 15 to the end of the cavity 13 away from the stirring shaft 3, thereby preventing malt from entering the cavity 13 and causing cleaning difficulties.

[0041] As a preferred technical solution of the present invention, positioning grooves 4 are provided at the upper and lower ends of the stirring shaft 3, a lower positioning ring 8 is provided below the threaded ring 10, a rotating ring 6 is fixedly connected to the inner wall of the lower positioning ring 8, the rotating ring 6 matches the positioning groove 4, a protective organ pipe 11 is fixedly connected to the top of the lower positioning ring 8, and the top of the protective organ pipe 11 is fixedly connected to the bottom of the threaded ring 10.

[0042] Specifically, the protective organ pipe 11 is used to protect and restrict the thread groove of the stirring shaft 3, so as to prevent malt from getting stuck on the thread groove of the stirring shaft 3, which makes it difficult to clean the stirring shaft 3.

[0043] As a preferred technical solution of the present invention, an upper positioning ring 7 is provided above the threaded ring 10, a positioning column 9 is fixedly connected to the bottom of the upper positioning ring 7, the lower end of the positioning column 9 passes through the threaded ring 10 and is fixedly connected to the top of the lower positioning ring 8, and the threaded ring 10 and the positioning column 9 are slidably connected.

[0044] Specifically, the upper positioning ring 7 , the lower positioning ring 8 and the threaded ring 10 are connected together by the positioning column 9 , so as to avoid misalignment of the angle between the threaded ring 10 and the lower positioning ring 8 , which would cause the protective organ pipe 11 to be twisted and damaged.

[0045] As a preferred technical solution of the present invention, a connection groove 12 is formed at the upper end of the threaded ring 10 , and a plurality of connection plates 23 are fixedly connected to the inner side of the lower end connection block 22 , and the connection plates 23 match the connection groove 12 .

[0046] Specifically, the lower end connecting block 22 and the threaded ring 10 are connected into a whole by the connecting plate 23 to avoid misalignment between the height of the extrusion block 32 and the height of the cavity 13, which makes it difficult for the extrusion block 32 to be aligned with the cavity 13.

[0047] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
