Description

Technical Field

[0001] This utility model relates to the field of storage devices, and in particular to a device for preserving high-humidity brewer's grains for animal feed. Background Technology

[0002] With the continuous development of the beer industry, brewer's grains, as one of the main wastes generated during the brewing process, pose a significant environmental pollution risk if discarded. Therefore, their rational utilization has become a focus of attention within the industry. Brewer's grains are rich in nutrients, including protein, fiber, and minerals, and have high reuse value.

[0003] However, brewer's grains contain a large amount of moisture (usually exceeding 75%), making them prone to mold and spoilage, which poses considerable challenges to their storage, transportation, and subsequent processing. Traditional storage methods, such as drying, dehydration, and cellaring, reduce the moisture content to below 60%, but these methods are costly, result in significant nutrient loss, and fail to achieve optimal fattening effects when fed to livestock.

[0004] Therefore, this application provides a high-humidity brewer's grains preservation device for animal feed to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-humidity brewer's grains preservation device for animal feed. This device has multiple functions including fermentation and storage preservation, is simple in structure, easy to use, and has excellent preservation and storage capabilities.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A high-humidity brewer's grains preservation device for animal feed includes a preservation tank and supports for supporting both ends of the preservation tank. The preservation tank includes an outer tank and an inner tank. The two ends of the inner tank are rotatably mounted inside the outer tank via bearings. The two ends of the outer tank are respectively fixedly mounted inside the two supports. The upper end face and the lower end face of the outer tank are provided with mounting grooves. An air vent and a drain are respectively fixedly installed in the two mounting grooves. The inner tank is composed of multiple frames surrounding a cylindrical frame, and a mesh and a gauze inner layer are respectively installed on the inner and outer sides. The cylindrical frame formed by the multiple frames is fixedly mounted with a fixing plate at both ends.

[0007] Furthermore, a motor base is fixedly installed on one side of the outer wall of one of the two supports, a drive motor is fixedly installed on the upper end face of the motor base, and a drive shaft is fixedly installed at the output end of the drive motor and the drive shaft is fixedly connected to the center of the outer wall of one of the fixed disks.

[0008] Furthermore, a liquid storage cavity is formed between the outer wall of the inner tank and the inner wall of the outer tank.

[0009] Furthermore, a feed inlet is fixedly provided at the midpoint of the outer wall of the other of the two fixed disks, and a sealing cap is installed at the end of the feed inlet away from the fixed disk.

[0010] Furthermore, a one-way valve is installed on both the air vent and the drain outlet, and both the air vent and the drain outlet penetrate the inner wall of the outer tank.

[0011] Furthermore, fresh brewer's grains with a moisture content of over 70% are poured into the inner tank through a filling machine using a special microbial agent at the feed inlet.

[0012] This utility model has the following beneficial effects: This utility model proposes a high-humidity brewer's grains preservation device for animal feed. The preservation tank is designed with inner and outer sides. The outer tank serves as a storage separation shell, collecting and draining the liquid accumulated in the inner tank after the natural seepage of moisture from the brewer's grains. Simultaneously, the outer tank is equipped with an air vent for air circulation during fermentation and a drain outlet for drainage, ensuring normal fermentation. After fermentation, both the drain outlet and the air vent are sealed to prevent air from entering the interior, thereby reducing the mold rate during storage, effectively extending storage time, slowing down the loss of nutrients in the raw materials, and achieving a good preservation effect.

[0015] 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.

[0016] Reference Figures 1-5 This utility model provides an embodiment of a high-humidity brewer's grains preservation device for animal feed, including a preservation tank 6 and supports 7 for supporting both ends of the preservation tank 6. The preservation tank 6 includes an outer tank 601 and an inner tank 602. The two ends of the inner tank 602 are rotatably disposed inside the outer tank 601 via bearings. The two ends of the outer tank 601 are respectively fixedly disposed inside the two supports 7. The upper end face and the lower end face of the outer tank 601 are provided with mounting grooves 8. Air vents 4 and drains 5 are respectively fixedly disposed in the two mounting grooves 8. The inner tank 602 is composed of a cylindrical frame formed by multiple frames 6022, and is composed of a grid 6021 and a gauze inner layer 6023 installed on the inner and outer sides respectively. The cylindrical frame formed by multiple frames 6022 is fixedly disposed at both ends with fixing plates 6024.

[0017] After the brewer's grains mixed with a special microbial agent are poured into the inner tank 602, fermentation is carried out. At this time, the entire tank ensures air circulation and smooth drainage. The inner tank 602 rotates inside the outer tank 601, causing the raw materials inside to turn over. This allows the edges and center, as well as the upper and lower layers of the material in different locations within the container, to exchange positions, ensuring that all materials have consistent fermentation conditions, uniform flavor, and maturity. After fermentation is completed, multiple openings are closed to create a sealed space within the entire tank, effectively preventing air from entering. This reduces the mold rate during storage, effectively extends storage time, slows down the loss of nutrients in the raw materials, and achieves a good preservation effect.

[0018] Reference Figure 1 A motor base 3 is fixedly installed on one side of the outer wall of one of the two supports 7. A drive motor 2 is fixedly installed on the upper end face of the motor base 3. A drive shaft 1 is fixedly installed at the output end of the drive motor 2 and the drive shaft 1 is fixedly connected to the center of the outer wall of one of the fixed disks 6024. Specifically, when the inner tank 602 needs to rotate, the drive motor 2 starts and drives the drive shaft 1 at the output end to rotate. The drive shaft 1 drives the fixed disk 6024 to rotate, thereby realizing the rotation of the entire inner tank 602 and achieving the effect of turning the raw materials. The drive motor 2 can also be connected to a reducer for use, thereby achieving a slow rotation drive effect.

[0019] Reference Figure 4A liquid storage cavity is formed between the outer wall of the inner tank 602 and the inner wall of the outer tank 601; Specifically, when the beer lees raw material mixed with the special microbial agent is poured into the inner tank 602, the beer lees raw material still contains a lot of water. During the turning and stilling process, the water that overflows will seep out from the inner tank 602, and then collect in the outer tank 601 and be discharged by the outer tank 601, so as to facilitate the discharge of the accumulated liquid.

[0020] Reference Figure 5 A feed inlet 9 is fixedly provided at the midpoint of the outer wall of the other of the two fixed disks 6024, and a sealing cover 10 is installed at the end of the feed inlet 9 away from the fixed disk 6024; Specifically, the feed inlet 9 facilitates the filling of raw materials, while the outer sealing cover 10 has a sealing gasket on its inner side. After the sealing cover 10 is fixed at the opening of the feed inlet 9, it seals the opening to ensure a sealed storage effect.

[0021] Reference Figure 1 One-way valves are installed on both the air vent 4 and the drain vent 5, and both the air vent 4 and the drain vent 5 penetrate the inner wall of the outer tank 601; the design of the one-way valves ensures the one-way inflow of air and the one-way discharge of accumulated liquid.

[0022] Fresh brewer's grains with a moisture content of over 70% are filled into the inner tank 602 through 9 inlets using a filling machine and special bacterial agent; Specifically, specialized microbial agents, such as feed fermentation agents or silage fermentation agents, are used to fill fresh brewer's grains with a moisture content of over 70% into the container using a filling machine. During fermentation, regular technical treatments are performed to complete the entire process, preventing mold growth, effectively extending storage time, and reducing the loss of nutrients in the raw materials. This ensures a balanced supply throughout the year, regardless of peak or off-peak seasons.

[0023] Working principle: During use, fresh brewer's grains with a moisture content of over 70% are filled into the inner tank 602 using a filling machine and a special inoculant. After the brewer's grains mixed with the special inoculant are filled into the inner tank 602, fermentation is carried out. At this time, the air vent 4 and the drain vent 5 are open. Then, the drive motor 2 starts and drives the drive shaft 1 at the output end to rotate. The drive shaft 1 drives the fixed plate 6024 to rotate, thereby realizing the rotation of the entire inner tank 602. The rotation of the inner tank 602 inside the outer tank 601 causes the raw materials inside to turn over, allowing the edges and center, upper and lower layers of the material in different positions in the container to exchange positions, ensuring that the fermentation conditions of all materials are consistent. After fermentation is completed, the multiple openings are closed to make the entire tank a sealed space, thereby effectively preventing air from entering the interior.

[0024] 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.
