Description

Technical Field

[0001] This utility model relates to the field of brewing technology, and in particular to an automatic stirrer for activating brewing yeast. Background Technology

[0002] Active dry yeast is a yeast cell product existing in solid form without losing its activity. Yeast activation involves restoring yeast activity before inoculating it into the fermentation tank. Effectively activating and protecting yeast in a dormant, dried state is not only a necessary measure for successful yeast activation and inoculation, but also the foundation and guarantee for maximizing the yeast's potential and perfectly achieving alcoholic fermentation. Currently, the rehydration and activation of active dry yeast mainly relies on manual methods. This involves placing the active dry yeast in a basin or bucket, adding fresh water to soak for a certain period of time, then stirring by hand or with a ladle to dissolve it, and finally filtering it through a sieve. The problems with this method are that the active dry yeast is not fully dissolved, resulting in insufficient uniformity, poor dispersibility and suspension. Due to poor dispersibility, the yeast particles are large, leading to low activation degree, low activation quality, and low activation efficiency.

[0003] A patent document with publication number CN212077032U discloses an activation device for dry yeast used in brewing. This patent involves unscrewing the cap of a yeast tank, pouring dry yeast into the tank, and having it fall from the bottom opening onto the center of a spreading disc that rotates with the agitator. Under centrifugal force, the yeast then enters a guide trough from the center of the spreading disc and finally falls out through the outlet at the outer edge of the guide trough. Part of the falling yeast falls directly into the nutrient solution in the outer area of ​​the activation chamber between two guide plates and is evenly mixed by the agitator. The other part falls onto the guide plates and is guided into the nutrient solution in the middle area of ​​the activation chamber, where it is evenly mixed by the agitator. Although this patent allows the dry yeast to fall into the nutrient solution and be stirred by the agitator, there is still a problem of the dry yeast clumping when it comes into contact with the nutrient solution. Simply using the agitator directly cannot completely break up the clumps, thus affecting the dissolution of the dry yeast.

[0004] Therefore, it is necessary to provide an automatic stirrer for activating brewing yeast to solve the above-mentioned technical problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

The upper side of the support base 6 is fixedly connected to the lower side of the tank body 4, and the outer wall of the tank body 4 is fixedly connected to the inner wall of the heat insulation cover 5. The tank body 4 is provided with the anti-caking component 1 for breaking up clumps of active dry yeast, and the tank body 4 is provided with the mixing component 2 for mixing warm water and active dry yeast. The lower receiving end of the temperature sensor 3 passes through and is fixedly connected to the upper side of the tank body 4.

[0031] The anti-caking component 1 includes a U-shaped plate 19, which is fixedly connected to the upper side of the heat insulation cover 5. The upper interface of the rotary joint 12 passes through and is fixedly connected to the U-shaped plate 19. The upper interface of the rotary joint 12 is fixedly connected to the feed hopper 11. The lower interface of the rotary joint 12 is fixedly connected to the upper end of the circular tube 14. The upper end of the circular tube 14 passes through and is fixedly connected to the center of the gear 13. The circular tube 14 is provided with a set of through grooves 16. The outer wall of the circular tube 14 is fixedly connected to a set of dispersing rods 15. The circular tube 14 is set inside the sieve cylinder 17. The upper side of the sieve cylinder 17 is fixedly connected to the upper side of the inner wall of the tank 4. The sieve cylinder 17 is provided with a set of sieve holes 18.

[0032] The mixing component 2 includes a gear ring 22 that meshes with the gear 13. The output shaft of a motor 21 is fixedly connected to the center of the gear ring 22. The motor 21 is fixedly connected to the U-shaped plate 19, and the output shaft of the motor 21 passes through the U-shaped plate 19. The upper end of a rotating rod 23 is fixedly connected to the center of the gear ring 22. The two ends of the rotating rod 23 are movably connected to the two sides of the tank body 4. A set of stirring rods 24 are fixedly connected to the lower part of the rotating rod 23. Symmetrical L-shaped scrapers 25 are fixedly connected to the lower end of the rotating rod 23. The two L-shaped scrapers 25 are respectively attached to the inner wall of the tank body 4.

[0033] The outer wall of the tank 4 is surrounded by the serpentine heating wire 8, and the electrodes at both ends of the serpentine heating wire 8 pass through and are fixedly connected to the heat preservation cover 5.

[0034] The lower end of the tank 4 is fixedly connected to the discharge valve 7.

[0035] The upper side of the tank body 4 is fixedly connected to the feed inlet 41, and the outer wall of the feed inlet 41 is threadedly connected to the inner wall of the feed inlet cover 42.

[0036] The wiring diagrams of the motor 21, the serpentine heating wire 8, and the temperature sensor 3 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the wiring diagrams of the motor 21, the serpentine heating wire 8, and the temperature sensor 3 will not be explained in detail.

[0037] Working principle: First, unscrew the feed port cover 42, add warm water into the tank 4 through the feed port 41, and screw the feed port cover 42 back on. Then, connect the two electrodes of the serpentine heating wire 8 to the external power supply, so that the serpentine heating wire 8 is energized to heat the tank 4, thereby raising the temperature inside the tank 4. Observe the temperature sensor 3. When the temperature inside the tank 4 reaches 38-40℃, the external power supply can be controlled. The heat preservation cover 5 can keep the tank 4 warm, so that the temperature of the tank 4 can be maintained at the required temperature.

[0038] Then, the active dry yeast is poured into the feed hopper 11, allowing it to pass through the feed hopper 11 into the rotary joint 12, the round tube 14, and out through a set of channels 16 into the sieve cylinder 17. It then passes through the sieve holes 18 into the tank 4. At this point, the motor 21 can be started. The motor 21 drives the rotating rod 23 to rotate via the gear ring 22. The rotating rod 23 drives a set of stirring rods 24 and an L-shaped scraper 25 to rotate, causing the stirring rods 24 to stir the warm water in the tank 4. Simultaneously, the gear ring 22 meshes with the gear 13, which drives the dispersing rod 15 to rotate via the round tube 14, causing the dispersing rod 15 to stir the water inside the sieve cylinder 17. The active dry yeast that clumps upon contact with warm water is broken up to prevent clumping. The broken-up active dry yeast gradually passes through the sieve holes 18 and comes into contact with the warm water in the tank 4. Yeast that clumps upon contact with warm water cannot pass through the sieve holes 18 and continues to be dispersed in the sieve cylinder 17. At the same time, a set of stirring rods 24 can stir and mix the warm water and active dry yeast, and two L-shaped scrapers 25 can scrape off the active dry yeast adhering to the inner wall of the tank 4. This allows the active dry yeast to dissolve quickly and fully in the warm water, and the appropriate temperature can improve the activation degree, activation quality and activation efficiency of the active dry yeast.

[0039] Once the active dry yeast has been processed, the motor 21 can be turned off and the discharge valve 7 can be opened to allow the contents of the tank 4 to be discharged through the discharge valve 7.

[0040] Beneficial effects: When active dry yeast is poured into the hopper 11, it enters the rotary joint 12 and the round tube 14 through the hopper 11, and is discharged into the sieve cylinder 17 through a set of channels 16. It then enters the tank 4 through the sieve holes 18. The mixing component 2 stirs the warm water, and at the same time, the anti-caking component 1 uses a set of dispersing rods 15 to disperse the active dry yeast that has clumped together in contact with the warm water in the sieve cylinder 17, preventing the active dry yeast from clumping together. At this time, the dispersed active dry yeast gradually comes into contact with the warm water in the tank 4 through the sieve holes 18, allowing the active dry yeast to quickly and fully dissolve in the warm water. The appropriate temperature can improve the activation degree, activation quality and activation efficiency of the active dry yeast.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
