Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically to a fermentation device for concentrated feed. Background Technology

[0002] Fermentation is required during feed processing. This is achieved by adding a fermenting agent and mixing it with the raw materials for fermentation. A search revealed a Chinese patent publication number, CN216473184U, which discloses a fermentation device for concentrated feed with uniform heating. While this device not only ensures uniform heating of the feed but also fully mixes the fermentation materials and fermentation liquid, improving fermentation efficiency, it has limitations regarding the fermentation method. Because the existing device is in a closed state during fermentation, it is only suitable for anaerobic fermentation. When aerobic fermentation is attempted, the poor internal oxygen flow makes it unsuitable. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a fermentation device for concentrated feed, which solves the problem mentioned in the background art that existing devices are only suitable for anaerobic fermentation and not for aerobic fermentation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fermentation device for concentrated feed, comprising a shell, a heat exchange tube, an air pump, a stirring frame, and an air outlet. A fermentation tank is housed inside the shell, and a mounting frame is welded to the bottom of the shell with screws. A drive motor is bolted to one side of the mounting frame. A transmission gear is fitted externally to the bottom output end of the drive motor, meshing with a driven gear. The driven gear is fitted externally to one top end of the stirring frame. An air outlet is provided on the surface of the stirring frame. One top end of the stirring frame is rotatably connected to a connector. One top end of the connector is welded to one end of a connecting pipe. The other end of the connecting pipe is connected to the air pump via a heat exchange tube. The air pump is installed on one side of the shell. Water inlets and outlets are provided on both ends of the shell, communicating with the interior. One side of the bottom of the fermentation tank is connected to a discharge port, and the top of the fermentation tank is connected to a feed inlet.

[0005] Preferably, the mixing rack has a hollow internal structure, and the interior of the mixing rack is connected to the interior of the connecting pipe through a connector, which helps to keep the mixing rack connected to the connector while it is rotating.

[0006] Preferably, the heat exchange tube is made of copper-aluminum composite material and is located inside one end of the outer shell. The heat exchange tube has a spiral structure, which helps to extend the travel distance of air inside the heat exchange tube, thereby facilitating the full heating of the air.

[0007] Preferably, there is a gap between the outer shell and the outer wall of the fermentation tank, and the outer wall of the fermentation tank is made of copper-aluminum composite material, which helps to improve the thermal conductivity of the fermentation tank.

[0008] Preferably, the air pump inlet is fitted with a filter cover, and the surface of the filter cover is evenly distributed with filter holes. By setting a filter cover on the outside of one end of the air pump, the outside air can be filtered before entering the air pump, thereby reducing the contamination of the feed.

[0009] This invention provides a fermentation device for concentrating feed. It has the following beneficial effects:

[0010] (1) The fermentation device for concentrated feed, when in use, the raw materials and fermentation powder are poured into the fermentation tank through the feed inlet, and then the drive motor drives the transmission gear to rotate. The transmission gear rotates and drives the stirring shaft to rotate, so that the stirring shaft can stir and mix the slurry in the fermentation tank, so that it can be fully mixed with the fermentation powder. At the same time, under the action of the air pump, the external air can be pumped into the heat exchange tube, and then the air can enter the stirring rack through the connecting pipe through the heat exchange tube, and finally be discharged through the air outlet on the surface of the stirring rack. This facilitates the external air to enter the slurry and become bubbles to contact the slurry, thereby improving the contact between the slurry and the air, and allowing the fermented feed to fully contact with oxygen. Thus, the device can carry out anaerobic fermentation and provide a good aerobic fermentation environment.

[0011] (2) In this kind of concentrated feed fermentation device, high-temperature hot water from the outside enters the space between the fermentation tank and the outer shell through the water inlet, thereby heating the fermentation tank so that the inside of the fermentation tank can provide the temperature required for fermentation. At the same time, the hot water can heat the heat exchange tube, and the airflow after heating inside the heat exchange tube can enter the slurry through the air outlet, thereby heating the inside of the slurry. This is beneficial for uniform heating of the feed and improving the heating effect.

[0012] This solves the problem that existing devices are only suitable for anaerobic fermentation and not for aerobic fermentation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0020] Example 1:

[0021] Please see Figure 1-5This utility model provides a technical solution: a fermentation device for concentrated feed, including a shell 1, a heat exchange pipe 9, an air pump 10, a stirring frame 16, and an air outlet 17. A fermentation tank 2 is housed inside the shell 1, and a mounting frame 3 is welded to the bottom of the shell 1 by screws. A drive motor 4 is bolted to one side of the mounting frame 3. A transmission gear 5 is fitted onto the outside of the bottom output end of the drive motor 4, meshing with a driven gear 6. The driven gear 6 is fitted onto the outside of the top end of the stirring frame 16. An air outlet 17 is provided on the surface of the stirring frame 16. One top end of the stirring frame 16 is rotatably connected to a connector 7. One top end of the connector 7 is welded to one end of a connecting pipe 8. The other end of the connecting pipe 8 is connected to the air pump 10 through the heat exchange pipe 9. The air pump 10 is installed on one side of the shell 1. Water inlets 14 and outlets 13 are provided on both ends of the shell 1, communicating with the interior. One side of the bottom of the fermentation tank 2 is connected to a discharge port 12, and the top of the fermentation tank 2 is connected to a feed inlet 15. The stirring frame 16 has a hollow interior. The device is constructed with a mixing rack 16 connected to a connecting pipe 8 via a connector 7. During operation, raw materials and yeast are poured into the fermentation tank 2 through the feed inlet 15. Driven by the drive motor 4, the transmission gear 5 rotates, simultaneously rotating the mixing shaft. This allows the mixing shaft to thoroughly mix the slurry inside the fermentation tank 2 with the yeast. Simultaneously, the air pump 10 pumps external air into the heat exchange tube 9, which then allows the air to enter the mixing rack 16 through the connecting pipe 8. Finally, the air is discharged through the air outlet 17 on the surface of the mixing rack 16. This allows external air to enter the slurry, forming bubbles that come into contact with the slurry, thus increasing the contact between the slurry and air. This ensures that the fermented feed is adequately exposed to oxygen, enabling the device to perform both anaerobic and aerobic fermentation simultaneously.

[0022] Example 2:

[0023] The heat exchange tube 9 is made of copper-aluminum composite material and is located inside one end of the outer shell 1. The heat exchange tube 9 has a spiral structure. There is a gap between the outer shell 1 and the outer wall of the fermentation tank 2. The outer wall of the fermentation tank 2 is also made of copper-aluminum composite material. The air pump 10 is fitted with a filter cover 11 on the outside of the air inlet. The filter cover 11 has filter holes evenly distributed on its surface. The high-temperature hot water from the outside enters the space between the fermentation tank 2 and the outer shell 1 through the water inlet 14, thereby heating the fermentation tank 2. This allows the fermentation tank 2 to provide the temperature required for fermentation. At the same time, the hot water can heat the heat exchange tube 9. The airflow after being heated inside the heat exchange tube 9 can enter the slurry through the air outlet 17, thereby heating the slurry and promoting uniform heating of the feed, thus improving the heating effect.

[0024] Working Principle: The device adds raw materials and yeast to the fermentation tank 2 through the feed inlet 15. The drive motor 4 rotates the transmission gear 5, which in turn drives the stirring shaft, achieving thorough stirring and mixing of the slurry within the fermentation tank 2. During stirring, the air pump 10 pumps external air into the heat exchange tube 9, which then enters the stirring frame 16 through the connecting pipe 8 and exits through the air outlet 17 on the surface of the stirring frame 16. This allows air to enter the slurry, forming bubbles and ensuring sufficient contact with the slurry, thereby increasing the contact area between the slurry and air and providing a good aerobic environment for the fermentation process. Simultaneously, high-temperature hot water enters the space between the fermentation tank 2 and the outer shell 1 through the water inlet 14, heating the fermentation tank 2 to maintain the appropriate temperature required for fermentation. The heated hot water also heats the heat exchange tube 9, allowing the hot airflow inside the heat exchange tube 9 to enter the slurry through the air outlet 17, achieving uniform heating of the slurry, improving the heating effect, and promoting the fermentation process.

[0025] It is worth noting that the entire device is controlled by an external master control button. Since the device matched with the control button is a common device and belongs to existing common knowledge technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
