Description

Technical Field

[0001] This utility model relates to the field of broad bean processing technology, and in particular to a combined coating machine for broad bean processing that combines slurry application and powder coating. Background Technology

[0002] Douban (fermented broad bean paste) processing involves multiple steps, including soaking, steaming, koji making, and fermentation, to produce the finished product, which is widely used in the production of condiments such as doubanjiang (fermented broad bean paste) and douchi (fermented black beans). Among these steps, the coating process is crucial for enhancing the flavor and extending the shelf life of douban. By evenly coating the surface of the douban with a layer of slurry and powder, a unique flavor and texture are imparted to the product, making it an important step affecting the quality of douban.

[0003] Existing soybean coating machines mostly employ a two-step operation: spraying slurry and roller coating. The equipment first sprays the prepared slurry evenly onto the surface of the soybeans through nozzles, and then feeds the coated soybeans into a drum containing dry powder, where the powder is applied by the rotation of the drum.

[0004] Existing coating machines are prone to issues such as excessively thick coating of soybean paste in some areas and uneven coating in others, which affects the appearance and taste of the product. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a combined coating machine for processing broad beans, which combines slurry application and powder coating, aiming to improve the problem of uneven powder coating in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A combined coating machine for processing broad beans (doubanjiang) includes a support frame, a coating tank, and a coating frame. The coating tank is equipped with a coating component, the top of the support frame is fixedly connected to an mounting plate, and the coating component is installed on the outside of the mounting plate.

[0008] The powder application assembly includes a motor, which is fixedly connected to the bottom of the mounting plate. A turntable is fixedly connected to the output end of the motor, and a connecting rod is rotatably connected to the top of the turntable. The other end of the connecting rod is rotatably connected to the top of the powder application frame.

The powder feeding frame is slidably connected to the inside of the sliding groove frames through the rollers. A protective box is fixedly connected to the bottom of the mounting plate, and the motor is located inside the protective box.

[0013] As a further description of the above technical solution:

[0014] One end of the powder frame is fixedly connected to a second motor, the output end of the second motor is fixedly connected to a rotating shaft, and a flap is fixedly connected to the outside of the rotating shaft.

[0015] As a further description of the above technical solution:

[0016] A feeding hopper is fixedly connected to the top of the support frame, and the slurry pool is fixedly connected to the outside of the feeding hopper.

[0017] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:

[0024] 1. In this invention, the fermented soybeans roll into the powder-coating frame, which is pre-filled with dry powder. Motor 1 is started, driving a turntable to rotate. The turntable transmits power through a connecting rod, causing the powder-coating frame to vibrate regularly. Rollers assist in maintaining the stability of the vibration. During the vibration, the fermented soybeans continue to roll, mixing thoroughly and evenly with the dry powder, effectively avoiding uneven powder application. Excess powder during mixing falls into a dry powder collection box through holes at the bottom of the powder-coating frame for reuse, reducing material waste. After the powder coating process is completed, Motor 2 is started, driving a rotating shaft to rotate a flap, smoothly conveying the processed fermented soybeans out.

[0025] 2. In this invention, the processed soybeans are placed in a feeding bucket. Under gravity, the bottom layer of soybeans slides down from the bucket's outlet and rolls in the slurry-spraying tank. A slurry pump is connected to the slurry inlet pipe, allowing for the selection of different slurries as needed. The slurry is then transported through the inlet pipe to the nozzle, where it is evenly sprayed from the bottom, precisely covering the surface of the rolling soybeans. Excess slurry after spraying flows into a collection frame through holes at the bottom of the slurry-spraying tank. A circulation pipe connected to the pump's input allows the collected slurry to re-enter the circulation system, greatly improving slurry utilization. Attached Figure Description

The coating tank 3 has a rectangular trough structure with multiple holes at the bottom. Its inner wall is smooth and made of corrosion-resistant material to prevent the slurry from eroding it and to ensure the service life of the equipment. A coating component is installed inside the coating tank 3. An mounting plate 8 is fixedly connected to the top of the support frame 1, and a coating component is installed on the outside of the mounting plate 8.

[0036] The powder application assembly includes a motor 10, which is fixedly connected to the bottom of the mounting plate 8. The motor 10 is securely fixed to the mounting plate 8 with bolts to ensure the stability of the motor during operation. A turntable 11 is fixedly connected to the output end of the motor 10. A connecting rod 12 is rotatably connected to the top of the turntable 11, and the other end of the connecting rod 12 is rotatably connected to the top of the powder application frame 13. Starting the motor 10 causes the turntable 11 to rotate, which in turn drives the connecting rod 12 to rotate, causing the powder application frame 13 to vibrate. Multiple rollers 14 are installed on both sides of the powder application frame 13. Slide frames 15 are fixedly connected to both ends of the mounting plate 8. The powder application frame 13 is slidably connected to the inside of the slide frames 15 via the rollers 14. The slide frames 15 have a U-shaped structure, providing a sliding track for the rollers 14. To ensure the stability of the powder feeding frame 13 during shaking, a protective box 9 is fixedly connected to the bottom of the mounting plate 8. The protective box 9 is a closed structure that can effectively protect the motor 10 from dust, debris and accidental collisions. The motor 10 is located inside the protective box 9. A motor 2 16 is fixedly connected to one end of the powder feeding frame 13. The motor 2 16 provides power for the rotation of the flip plate 17. A rotating shaft 18 is fixedly connected to the output end of the motor 2 16. The flip plate 17 is fixedly connected to the outside of the rotating shaft 18. When the motor 2 16 starts, it drives the rotating shaft 18 and the flip plate 17 to rotate, realizing the discharging operation of the soybean paste. A dry powder collection box 25 is installed inside the bracket 1. The dry powder collection box 25 is located at the bottom of the powder feeding frame 13 and is used to collect excess powder during the powder feeding process to reduce powder waste.

[0037] Reference Figures 1-3The slurry spraying assembly includes multiple nozzles 4, which are evenly distributed inside and above the slurry spraying tank 3 to ensure stable slurry spraying. All nozzles 4 are installed inside the slurry spraying tank 3. A collection frame 7 is fixedly connected to the bottom of the slurry spraying tank 3 to collect excess slurry during the spraying process. Multiple slurry inlet pipes 5 are fixedly connected to the outside of the slurry spraying tank 3. A circulation pipe 6 is fixedly connected to the outside of the collection frame 7. The slurry inlet pipes 5 are connected to an external slurry storage device using quick-connect couplings for easy replacement of different types of slurry. The circulation pipe 6 is fixedly connected to the outside of the collection frame 7, with one end connected to the collection frame 7 and the other end connected to the input end of the slurry pump, enabling slurry recycling.

[0038] Reference Figure 1 , Figure 2 and Figure 6 The top of the support frame 1 is fixedly connected to the feeding bucket 2, and the slurry pool 3 is fixedly connected to the outside of the feeding bucket 2. The feeding bucket 2 is cylindrical and is fixed to the top of the support frame 1 by welding. Its capacity is designed according to production needs and can store a certain amount of soybean paste. The outer sides of the slurry tank 3 and the feeding hopper 2 are tightly connected, facilitating the smooth entry of soybean paste from the feeding hopper 2 into the slurry tank 3. A protective base 23 is fixedly connected to the top of the support 1. The protective base 23 is fixedly welded to the top of the support 1, providing stable support for the mixing hopper 19. The mixing hopper 19 is fixedly connected to the top of the protective base 23. Its internal space is used to mix the slurry-treated and powder-treated soybean paste. A motor 20 is fixedly connected to the bottom of the mixing hopper 19. The motor 20 is fixedly bolted to the center of the bottom of the mixing hopper 19, providing power for the mixing process. A stirring rod 21 is fixedly connected to the top of the motor 20. A stirring paddle 22 is fixedly connected to the outer side of the stirring rod 21. By starting the motor 20, the mixing is slow and the powder and slurry are mixed evenly to complete the coating process. The mixture is then discharged from the discharge pipe 24. The motor 20 is located inside the protective base 23, and the discharge pipe 24 is fixedly connected to the outer side of the mixing hopper 19.

[0039] Working principle: First, the processed soybeans are placed in the feeding bucket 2. Due to gravity, the soybeans at the bottom will come out from the outlet of the feeding bucket 2 and roll in the slurry tank 3. At this time, the slurry pump is connected to the slurry inlet pipe 5. Different slurries are selected and transported to the nozzle 4 through the slurry inlet pipe 5. The slurry is sprayed from the bottom of the nozzle 4 and evenly sprinkled on the soybeans. Excess slurry will flow into the collection frame 7 through the holes at the bottom of the slurry tank 3. The circulation pipe 6 is connected to the input end of the pump, which can maximize the utilization rate of the slurry.

[0040] After multiple slurry applications, the fermented soybeans roll into the powder loading frame 13, which is then filled with powder. Motor 10 is started, causing the turntable 11 to rotate. The turntable 11 drives the connecting rod 12 to rotate, causing the powder loading frame 13 to vibrate. The roller 14 makes the vibration more stable. This vibration ensures that the fermented soybeans are evenly mixed with the dry powder during rolling, preventing the powder from being too thick or not coated at all. Excess powder enters the dry powder collection box 25 through the holes at the bottom of the powder loading frame 13 for secondary use, reducing powder waste. After powder loading is complete, motor 2 is started, causing the rotating shaft 18 and the flap 17 to rotate, thus discharging the fermented soybeans.

[0041] After being coated with slurry and powder, the fermented soybeans enter the mixing tank 19. The motor 20 is started and slowly stirred to ensure that the powder and slurry are evenly mixed so that the coating can be completed. Then, the soybeans are discharged from the discharge pipe 24. The discharge pipe 24 is equipped with an electric baffle that can control the opening and closing.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
