Description

Technical Field

[0001] This utility model relates to the field of vacuum storage device technology, specifically to a vacuum-sealed soybean meal preservation and storage device. Background Technology

[0002] In the modern feed processing industry, soybean meal, with its high protein content and reasonable amino acid composition, has become a core protein raw material for animal feed such as livestock, poultry, and aquatic products, occupying an important position in feed formulation. The quality of soybean meal directly affects the nutritional value of feed and the efficiency of animal breeding. Storage conditions play a key role in maintaining the quality of soybean meal. Good storage methods can effectively prevent problems such as oxidation, mold, and pests during the storage process, avoiding the loss of nutrients and the decline in quality.

[0003] Currently, traditional methods of storing soybean meal mainly involve using ordinary warehouses or simple packaging bags. When stored in ordinary warehouses, soybean meal is easily affected by changes in environmental humidity and temperature. In humid environments, soybean meal readily absorbs moisture, creating conditions for mold growth and leading to mold contamination. This not only reduces the nutritional value of soybean meal but may also produce harmful toxins, endangering animal health. Under high temperatures, the oil components in soybean meal are prone to oxidative rancidity, damaging the protein structure and affecting feed palatability and animal digestibility. Soybean meal stored in simple packaging bags has poor sealing, making it difficult to isolate air and external impurities, and cannot effectively prevent oxidation and pest infestation. Furthermore, the packaging bags are easily damaged during handling and stacking, further reducing the quality of stored soybean meal.

[0004] To achieve better preservation, soybean meal is typically stored in vacuum-sealed preservation devices. Many types of vacuum-sealed preservation devices are available on the market. Most of these devices use a vacuum pump connected to pipes to extract air from the storage unit, achieving a vacuum preservation effect. However, most vacuum-sealed preservation devices rely solely on the vacuum pump to remove gas. As the soybean meal accumulates inside the device, the upper layer compresses and obstructs the lower layer. Without a corresponding stirring component, the air contained in the lower layer of soybean meal cannot be completely extracted, failing to create a near-vacuum environment and affecting the preservation effect. Therefore, we propose a vacuum-sealed soybean meal preservation and storage device. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum-sealed soybean meal preservation and storage device to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0031] 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.

[0032] Please see Figures 1-3 This utility model provides a technical solution: a vacuum-sealed soybean meal preservation and storage device, including a storage tank 1. A feed pipe 3 for material entry is fixedly installed on the top of the storage tank 1. A first valve 30 is fixedly installed on the feed pipe 3. The inner diameter of the feed pipe 3 is between 5cm and 12cm. A threaded cap 31 is threadedly connected to the top of the feed pipe 3. When soybean meal is being fed, the feeding speed and flow rate can be controlled by opening the first valve 30. After feeding is completed, the first valve 30 is closed to initially prevent outside air from entering the storage tank 1. With the threaded cap 31 threadedly connected to the top of the feed pipe 3, a double seal is achieved, isolating the storage tank 1 from the outside world when not feeding, effectively preventing air and moisture from entering, avoiding oxidation and mold growth of the soybean meal, making the storage environment more stable, and achieving the purpose of improving the preservation effect of soybean meal.

[0033] like Figure 1 As shown, a suction pipe 4 for venting gas is fixedly installed on the top of the storage tank 1. A one-way valve 40 is also fixedly installed on the suction pipe 4. A suction pipe connector 42 is fixedly installed at the end of the suction pipe 4. The suction pipe connector 42 is connected to the suction end of an external vacuum pump. A second valve 41 is fixedly installed on the suction pipe 4. After opening the second valve 41, the air inside the storage tank 1 can be extracted. The one-way valve 40 can prevent gas backflow and ensure that the vacuum environment inside the storage tank 1 is maintained after the air is extracted, avoiding the re-entry of air and affecting the preservation effect. This keeps the storage tank 1 in a stable vacuum state, thereby extending the shelf life of soybean meal.

[0034] In this embodiment, a sealing ring 16 is fixedly installed at the center of the upper surface of the storage tank 1, and a stirring motor 2 is fixedly installed on the sealing ring 16. A motor support 23 is fixedly installed on the housing of the stirring motor 2. A sealing ring 21 is provided on the top surface of the sealing ring 16. The motor support 23 and the sealing ring 16 are detachably connected. The motor support 23 presses the sealing ring 21 tightly against the top surface of the sealing ring 16. A mechanical seal 15 is provided at the center of the top surface of the storage tank 1. A long shaft 20 passes through the mechanical seal 15 and is rotatably connected to the mechanical seal 15. While ensuring the stable installation of the stirring motor 2, a good sealing structure is formed to prevent air leakage at the connection between the stirring motor 2 and the storage tank 1. At the same time, the mechanical seal 15 can continue to seal. The double sealing measures comprehensively ensure the sealing performance of the stirring motor 2 and the long shaft 20, which greatly improves the sealing performance of the storage tank 1, effectively isolates external factors and ensures the storage quality of soybean meal.

[0035] like Figure 2 and Figure 3 As shown, a long shaft 20 is fixedly installed at the end of the output shaft of the stirring motor 2. The long shaft 20 extends vertically into the storage tank 1. A stirring blade 22 is fixedly installed on the shaft of the long shaft 20 located in the storage tank 1. The stirring blade 22 rotates to expel air mixed in the material. During the air extraction process, the stirring motor 2 drives the long shaft 20 to rotate the stirring blade 22, which fully turns over the accumulated soybean meal, breaks the compression and obstruction of the upper layer of soybean meal to the lower layer, and allows the air in the lower layer of soybean meal to be smoothly discharged. Working in conjunction with the suction pipe 4, it achieves more thorough air extraction, effectively solves the problem of residual air in traditional devices, and creates a more vacuum-like environment in the storage tank 1, thereby significantly enhancing the preservation effect of soybean meal.

[0036] like Figure 1 As shown, a conical cylinder 10 is fixedly installed at the bottom of the storage tank 1. The inner wall of the conical cylinder 10 is inclined downward at a angle of 45° to 60°. A discharge pipe 11 is fixedly installed at the bottom of the conical cylinder 10, and a discharge valve 12 is fixedly installed on the discharge pipe 11. By utilizing gravity, the soybean meal can smoothly slide and accumulate towards the discharge pipe 11 during discharge. In conjunction with the discharge pipe 11 and the discharge valve 12, the discharge valve 12 is opened during discharge, and the soybean meal can be quickly and conveniently discharged from the discharge pipe 11, reducing residue, improving discharge efficiency, and making the discharge operation easier and more efficient, thereby facilitating material output and improving work efficiency.

[0037] like Figure 1As shown, multiple support legs 13 are fixedly installed at the bottom of the storage tank 1, and rollers 14 are fixedly installed at the bottom of the support legs 13, enabling the storage tank 1 to move. Operators can easily push the storage tank 1 to adjust its position according to actual needs. Whether changing the storage location or moving the device during cleaning and maintenance, it is more labor-saving and convenient, greatly improving the flexibility of the device and achieving the effect of improving the convenience of using the storage device and reducing the burden of manual operation.

[0038] Finally, it should be noted that the stirring motor 2 and the vacuum pump and pressure gauge on the vacuum pump involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0039] When using the vacuum-sealed soybean meal preservation and storage device of this utility model, connect the suction pipe connector 42 to the suction end of the external vacuum pump, and check whether the first valve 30 and threaded cap 31 on the feed pipe 3, and the second valve 41 and check valve 40 on the suction pipe 4 are in the closed state to ensure the sealing of the device.

[0040] When feeding begins, unscrew the threaded cap 31, open the first valve 30, and transport the soybean meal into the storage tank 1 through the feed pipe 3. The first valve 30 can be adjusted to control the feeding speed and flow rate as needed. After feeding is completed, close the first valve 30, tighten the threaded cap 31, and complete the feeding seal.

[0041] Next, the air extraction operation is performed. The second valve 41 is opened and the external vacuum pump is started. The vacuum pump extracts the air from the storage tank 1 through the suction pipe 4. At the same time, the stirring motor 2 is turned on. The stirring motor 2 drives the long shaft 20 to rotate the stirring blades 22, turning the soybean meal and allowing the air contained in the soybean meal to be fully discharged. After the required vacuum degree is reached, this process can be observed from the pressure gauge on the vacuum pump. Then, the second valve 41 and the stirring motor 2 are closed. The check valve 40 ensures that the vacuum environment is stable. At this time, the second valve 41 is closed.

[0042] When unloading, open the unloading valve 12, or unscrew the threaded cover 31 and open the first valve 30 to make the air pressure inside and outside the storage tank 1 the same. Under the action of the conical cylinder 10, the soybean meal slides and gathers towards the unloading pipe 11 by gravity and is discharged. If the device needs to be moved, the operator can push the storage tank 1, and the rollers 14 at the bottom of the bottom support leg 13 will help to easily adjust the position of the device.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
