Description

Technical Field

[0001] This utility model relates to a hops dry feeding device, belonging to the field of beer production technology. Background Technology

[0002] In the beer brewing process, hops are usually dry-added to the beer. Dry-adding hops refers to the brewing technique of adding hops in batches again or multiple times during beer fermentation. Dry-adding can maximize the hop aroma, and since the hops are not boiled at this stage, their bitterness cannot be fully released, so it will not affect the final bitterness of the beer.

[0003] An existing patent (CN221460325U) describes a dry hop feeding device. This device adds hops to a storage tank via a feed pipe, closes the feed valve, and places the storage tank in a fixed pipe. At this point, the sealing cap is tightened, and the venting device is opened to expel oxygen from the reaction chamber, preventing oxidation of the fermentation liquid and affecting the beer's taste. Then, the inlet valve is opened, causing the fermentation liquid in the brewing tank to move into the reaction chamber under pressure, filling it and bringing it into contact with the hops in the storage tank. The outlet valve is then opened, activating the water pump to deliver the fermentation liquid containing flavor components to the brewing tank. This circulation of the fermentation liquid within the reaction chamber effectively improves hop utilization. The device can be further optimized by closing the inlet and outlet valves. Simultaneously, the inlet pump stops working, and the drain pump starts working, thus transporting the fermentation liquid inside the reaction tank to the brewing tank. After the transport is completed, the connecting valve is closed, the sealing cap is rotated, and the storage tank is removed from the fixed pipe. The feed valve is then opened, and the hop residue is removed from the storage tank, thus preventing the hops from soaking in the fermentation liquid for too long, which could cause the beer to have a raw, grassy taste. However, this device can only add hops once, and cannot achieve multiple automatic dry-feeding of hops. Therefore, it is necessary to manually disassemble and reassemble the dry-feeding equipment repeatedly to refill it, reducing the convenience of multiple dry-feeding of hops. Furthermore, this device cannot automatically add quantitative amounts of hops during dry-feeding, and the residue still needs to be manually removed and discharged after the hops have fully reacted with the fermentation liquid. It cannot achieve automatic timed and quantitative feeding, nor can it automatically discharge the residue. Utility Model Content

[0004] The purpose of this invention is to provide a hops dry-feeding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dry hop feeding device includes a fermentation tank, a sealed feeding box, and a hop storage box. The sealed feeding box is sealed to the upper right side of the fermentation tank. A rotating inner frame is rotatably connected inside the sealed feeding box. An electric telescopic rod is fixedly connected to the outer side of the lower side of the upper wall of the rotating inner frame. A top frame plate is fixedly connected to the lower end of the electric telescopic rod. An alloy mesh cylinder is fixedly connected to the lower end of the top frame plate. A spacer plate is fixedly connected to the inner side of the rotating inner frame. The outer side of the spacer plate is in contact with the sealed feeding box. A guide box is sealed to the upper left side of the sealed feeding box. The hop storage box is sealed to the upper end of the guide box. A bottom sealing plate is sealed to the inner side of the lower wall of the rotating inner frame. The bottom sealing plate is in contact with the alloy mesh cylinder. A water injection pipe is sealed to the upper right side of the sealed feeding box. A drain pipe is sealed to the lower right side of the sealed feeding box.

[0007] Furthermore, a stepper motor is fixedly connected at the middle position of the upper end of the sealed feeding box, and the output shaft of the stepper motor is fixedly connected to the rotating inner frame.

[0008] Furthermore, a first motor is fixedly connected to the middle position inside the top frame plate, and a stirring blade is rotatably connected to the middle position at the lower end of the top frame plate. The stirring blade is fixedly connected to the output shaft of the first motor.

[0009] Furthermore, a vacuum pump is sealed to the rear of the upper end of the sealed feeding box, and dry feeding ports are provided on the front of the lower end wall of the sealed feeding box, the front right side of the upper end wall of the fermentation tank, and the lower end wall of the rotating inner frame.

[0010] Furthermore, a second motor is fixedly connected to the left side of the guide box, and a guide wheel is fixedly connected to the right end of the output shaft of the second motor. A quantitative guide groove is provided on the inner side of the guide wheel.

[0011] Furthermore, a feed inlet is provided on the outer side of the upper wall of the rotating inner frame, and a telescopic guide pipe is sealed and connected at the feed inlet of the rotating inner frame, and the telescopic guide pipe is sealed and connected to the top frame plate.

[0012] Furthermore, a water guide pipe is sealed and connected to the lower side of the upper wall of the rotating inner frame near the middle position. The position of the water guide pipe corresponds to the position of the water injection pipe. A water guide circular frame is sealed and connected to the inner end of the water guide pipe. The water guide circular frame is fixedly connected to the rotating inner frame. A flushing nozzle is sealed and connected to the lower end of the water guide circular frame.

[0013] Furthermore, the outer side of the alloy mesh cylinder is provided with a fixed sleeve, which is fixedly connected to the rotating inner frame. A limiting slide rod is slidably connected to the inner side of the fixed sleeve. The limiting slide rod is fixedly connected to the bottom sealing plate and slidably connected to the rotating inner frame. The surface of the limiting slide rod is covered with a spring.

[0014] The beneficial effects of this utility model are:

[0015] This invention utilizes a stepper motor to rotate the inner frame, which in turn rotates four alloy mesh cylinders. An electric telescopic rod drives the top frame plate to move the alloy mesh cylinders up and down. This allows the front alloy mesh cylinder to feed hops into the fermentation tank through the dry feeding inlet. A first motor rotates the stirring blades, agitating the hops and ensuring thorough contact and reaction with the fermentation liquid. After a single dry feeding reaction, subsequent alloy mesh cylinders feed subsequent hops into the fermentation tank, enabling automatic multiple dry feedings. A sealing plate divides the rotating inner frame into sealed areas, and a vacuum pump prevents air from entering, further enhancing the convenience of dry feeding. In this invention, hop particles in the hop storage box are quantitatively fed into a quantitative feed trough, and a second motor drives the feed wheel... The hops move downwards, allowing a measured amount of hops to intermittently enter the alloy mesh cylinder through the telescopic guide pipe. Supported by the bottom sealing plate, the bottom sealing plate follows the hops into the fermentation tank, causing the limiting slide rod to move downwards and compressing the spring. After the alloy mesh cylinder rises, the spring extends, allowing the bottom sealing plate to fit against the lower wall of the rotating inner frame. Once the alloy mesh cylinder has moved the residue to the right, the electric telescopic rod lifts it again, disconnecting the alloy mesh cylinder from the bottom sealing plate. Water is then injected through the water injection pipe, flowing through the guide pipe into the guide frame and spraying out through the flushing nozzles to flush the used alloy mesh cylinder on the right side. This allows the residue to be automatically discharged through the drain pipe, achieving automatic metered hop feeding and residue discharge without manual cleaning or feeding, greatly improving the ease of use of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Example 1 Figures 1-5 This utility model provides a technical solution:

[0025] A hop feeding device includes a fermentation tank 1, a sealed feeding box 2, and a hop storage box 9. The sealed feeding box 2 is sealed to the upper right side of the fermentation tank 1. A rotating inner frame 3 is rotatably connected inside the sealed feeding box 2. An electric telescopic rod 4 is fixedly connected to the outer side of the lower side of the upper wall of the rotating inner frame 3. A top frame plate 5 is fixedly connected to the lower end of the electric telescopic rod 4. An alloy mesh cylinder 6 is fixedly connected to the lower end of the top frame plate 5. A spacer plate 7 is fixedly connected to the inner side of the rotating inner frame 3. The outer side of the spacer plate 7 is in contact with the sealed feeding box 2. A stepper motor 13 is fixedly connected to the middle position of the upper end of the sealed feeding box 2. The output shaft of the stepper motor 13 is fixedly connected to the rotating inner frame 3. A first motor 14 is fixedly connected to the middle position of the inner side of the top frame plate 5. A stirring blade 15 is rotatably connected to the middle position of the lower end of the top frame plate 5. The stirring blade 15 is fixedly connected to the output shaft of the first motor 14. A vacuum pump 16 is sealed to the rear side of the upper end of the sealed feeding box 2. Dry feeding ports 17 are provided on the front side of the lower end wall of the feeding box 2, the front right side of the upper end wall of the fermentation tank 1, and the lower end wall of the rotating inner frame 3. The rotation of the inner frame 3 is achieved by the rotation of the stepper motor 13, which in turn causes the four alloy mesh cylinders 6 to rotate. The top frame plate 5 is driven by the electric telescopic rod 4 to move the alloy mesh cylinders 6 up and down, allowing the alloy mesh cylinder 6 at the front to feed the hops into the fermentation tank 1 through the dry feeding port 17. The rotation of the first motor 14 causes the stirring blade 15 to agitate the hops, ensuring that the hops can fully contact and react with the fermentation liquid. After a single dry feeding reaction, the subsequent alloy mesh cylinders 6 can feed the subsequent hops into the fermentation tank 1 in sequence, realizing automatic multiple dry feeding of hops. The spacer sealing plate 7 can divide the rotating inner frame 3 into sealed areas, and the vacuum pump 16 can prevent air from entering, improving the convenience of dry feeding of hops.

[0026] Please refer to Example 2 Figure 1 , Figure 2 and Figure 5The difference between this embodiment and Embodiment 1 is as follows: A guide box 8 is sealed to the upper left side of the sealed feeding box 2; a hop storage box 9 is sealed to the upper end of the guide box 8; a bottom sealing plate 10 is sealed to the lower inner wall of the rotating inner frame 3, and the bottom sealing plate 10 is in close contact with the alloy mesh cylinder 6; a water injection pipe 11 is sealed to the upper right side of the sealed feeding box 2; a drain pipe 12 is sealed to the lower right end of the sealed feeding box 2; a second motor 18 is fixedly connected to the left side of the guide box 8; a guide wheel 19 is fixedly connected to the right end of the output shaft of the second motor 18; a quantitative guide groove 20 is opened on the inner side of the guide wheel 19; and a feed inlet is opened on the outer side of the upper wall of the rotating inner frame 3. A telescopic guide pipe 21 is sealed at the feed inlet of the inner frame 3, and the telescopic guide pipe 21 is sealed to the top frame plate 5. A water guide pipe 22 is sealed to the lower side of the upper wall of the inner frame 3 near the middle position, and the position of the water guide pipe 22 corresponds to the position of the water injection pipe 11. A water guide circular frame 23 is sealed to the inner end of the water guide pipe 22, and the water guide circular frame 23 is fixedly connected to the inner frame 3. A flushing nozzle 24 is sealed to the lower end of the water guide circular frame 23. A fixed sleeve 25 is provided on the outer side of the alloy mesh cylinder 6, and the fixed sleeve 25 is fixedly connected to the inner frame 3. A limit slide rod 26 is slidably connected to the inner side of the fixed sleeve 25, and the limit slide rod 26 is sealed to the bottom. The plates 10 are fixedly connected, and the limiting slide rod 26 is slidably connected to the rotating inner frame 3. The surface of the limiting slide rod 26 is covered with a spring 27. The hops in the hop storage box 9 can fall quantitatively into the quantitative guide trough 20. The rotation of the second motor 18 causes the guide wheel 19 to move the hops downward, so that the quantitative hops can intermittently enter the alloy mesh cylinder 6 through the telescopic guide tube 21 and be supported by the bottom sealing plate 10. When the hops enter the fermentation tank 1, the bottom sealing plate 10 follows and causes the limiting slide rod 26 to move downward, and the spring 27 is compressed. When the alloy mesh cylinder 6 is raised, the spring 27 extends. The bottom sealing plate 10 can be attached to the inner side of the lower end wall of the rotating inner frame 3. After the alloy mesh cylinder 6 moves the material residue to the right side, the alloy mesh cylinder 6 can be disconnected from the bottom sealing plate 10 by the electric telescopic rod 4. The water source is injected through the water injection pipe 11, and the cleaning water enters the water guide frame 23 through the water guide pipe 22. Then it is sprayed out through the flushing nozzle 24 to flush the alloy mesh cylinder 6 after use on the right side. The material residue can be flushed by the water source and automatically discharged through the sewage pipe 12. This enables the automatic quantitative feeding of hops and the automatic discharge of material residue without the need for manual cleaning and feeding, which greatly improves the ease of use of the device.

[0027] The working principle of this utility model is as follows: When in use, the rotation of the stepper motor 13 causes the inner frame 3 to rotate, which in turn causes the four alloy mesh cylinders 6 to rotate. Driven by the electric telescopic rod 4, the top frame plate 5 moves the alloy mesh cylinders 6 up and down, allowing the front alloy mesh cylinder 6 to feed hops into the fermentation tank 1 through the dry feeding port 17. The rotation of the first motor 14 causes the stirring blades 15 to agitate the hops, ensuring sufficient contact and reaction between the hops and the fermentation liquid. After a single dry feeding reaction, subsequent alloy mesh cylinders 6 feed subsequent hops into the fermentation tank 1, achieving automatic multiple dry feedings. The spacer plate 7 divides the inner frame 3 into sealed areas, and the vacuum pump 16 prevents air from entering, improving the convenience of dry feeding. Furthermore, the hop particles in the hop storage box 9 can be quantitatively fed into the quantitative guide trough 20, and the rotation of the second motor 18 causes the guide wheel 19 to... This allows the hops to move downwards, enabling a measured amount of hops to intermittently enter the alloy mesh cylinder 6 through the telescopic guide tube 21 and be supported by the bottom sealing plate 10. When the hops enter the fermentation tank 1, the bottom sealing plate 10 follows, causing the limiting slide rod 26 to move downwards, compressing the spring 27. After the alloy mesh cylinder 6 is raised, the spring 27 extends, allowing the bottom sealing plate 10 to adhere to the inner side of the lower end wall of the rotating inner frame 3. After the alloy mesh cylinder 6 moves the residue to the right, the electric extension... The retraction rod 4 is raised again, allowing the alloy mesh cylinder 6 to disconnect from the bottom sealing plate 10. Water is injected through the water injection pipe 11, allowing cleaning water to enter the water guide frame 23 through the water guide pipe 22, and then sprayed out through the flushing nozzle 24. This flushes the alloy mesh cylinder 6 after use, allowing the residue to be flushed by the water source and automatically discharged through the sewage pipe 12. This enables automatic quantitative feeding of hops and automatic discharge of residue, eliminating the need for manual cleaning and feeding, and greatly improving the ease of use of the device.
