Description

Technical Field

[0001] This utility model relates to the field of sterilization, and in particular to a sterilization device for microbial fermented feed. Background Technology

[0002] Currently, commonly used feed sterilization methods include high-temperature steam sterilization, irradiation sterilization, and chemical fumigation sterilization. Among them, high-temperature steam sterilization is widely used in the feed industry due to its simple operation, low cost and high efficiency, no residual toxicity, and stable sterilization effect.

[0003] High-temperature steam sterilization equipment mainly includes a sterilization cylinder, a steam generator, and a supporting control system. Its basic working principle is to introduce high-temperature steam into the sterilization cylinder, so that the feed is kept in a high-temperature and high-humidity environment for a certain period of time to achieve the purpose of killing microorganisms.

[0004] However, due to the inconsistent gap sizes between the piled feed, high-temperature steam cannot penetrate the entire feed layer evenly and quickly, resulting in some feed areas failing to meet the standards for effective sterilization in terms of temperature and humidity, thus affecting the overall sterilization efficiency. Utility Model Content

[0005] To overcome the drawback that inconsistent gap sizes between piled feed prevent high-temperature steam from penetrating the entire feed layer evenly, resulting in some feed areas failing to meet effective sterilization standards in terms of temperature and humidity, thus affecting overall sterilization efficiency, this invention provides a sterilization device for microbial fermented feed.

[0006] Technical solution: A sterilization device for microbial fermented feed includes a sterilization cylinder, a sealing block, and a feed pipe; the sterilization cylinder has at least one discharge port; the discharge port is screwed to a sealing block; the sterilization cylinder is connected to the feed pipe; it also includes a conveying pipe, a chassis, plow-shaped plates, and a power assembly; the sterilization cylinder is fixedly connected to the conveying pipe; the conveying pipe has several air outlets; the sterilization cylinder is rotatably connected to the chassis; the chassis is fixedly connected to several plow-shaped plates for stirring the feed, and all plow-shaped plates are in contact with the sterilization cylinder; the sterilization cylinder is connected to a power assembly for driving the chassis and its connected parts to rotate, and the power assembly is connected to the chassis.

[0007] To further explain, the power assembly includes a motor, a gear, and a gear ring; the sterilization cylinder is fixedly connected to the motor; the output shaft of the motor is fixedly connected to the gear; the chassis is fixedly connected to the gear ring, and the gear ring meshes with the gear.

[0008] Further explanation: It also includes a distribution plate; the sterilization cylinder is fixedly connected to the distribution plate for distributing feed; the distribution plate has a cavity, and the cavity is connected to the conveying pipe; the cavity has several air outlets.

[0009] Further explanation: It also includes airbags and springs; several airbags are fixedly connected to the diversion plate; several through holes are opened in the diversion plate; each airbag has several channels, and each channel is connected to the corresponding through hole; each airbag is fixedly connected to a spring for bouncing the feed that falls onto the diversion plate upward.

[0010] To further explain, it also includes a second motor, a rotating shaft, and a dispersing plate; the second motor is fixedly connected to the feed pipe; the rotating shaft is rotatably connected to the feed pipe, and the rotating shaft is fixedly connected to the output shaft of the second motor; the second motor is fixedly connected to several dispersing plates that are staggered.

[0011] To further clarify, each sealing block is equipped with a handle.

[0012] To further explain, the chassis is designed as an inverted frustum-shaped structure.

[0013] Compared with the prior art, the present invention has the following advantages: by using a plow-shaped plate to make the feed evenly turn over and circulate in the sterilization cylinder, the contact area and contact efficiency between the feed and the high-temperature steam are increased, thereby enhancing the sterilization effect. This effectively avoids the problem that uneven gaps caused by feed accumulation prevent the high-temperature steam from quickly and evenly penetrating the entire feed layer, resulting in some areas not meeting the effective sterilization standards in terms of temperature and humidity.

[0014] By adding a distribution plate and setting a cavity and an air outlet II on the distribution plate, the feed is dispersed when it moves downward along the surface of the distribution plate, so that the high-temperature steam flowing out from the air outlet II can better contact the feed, thereby allowing the feed to be pre-sterilized evenly and further enhancing the pre-sterilization effect.

[0015] By adding through holes, air bladders, and springs to the distribution plate, the springs bounce the feed that falls onto it into the air, making the feed more dispersed, thereby increasing the contact area between the feed and the high-temperature steam flowing out from the air outlet, and thus further enhancing the pre-sterilization effect.

However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0023] Example: Sterilization device for microbial fermented feed, such as Figures 1-5 As shown, it includes a sterilization cylinder 1, a sealing block 2, and a feed pipe 3; the sterilization cylinder 1 has two discharge ports 101; each discharge port 101 is screwed with a sealing block 2 for sealing it; each sealing block 2 is provided with a handle 201 for easy manual rotation; the sterilization cylinder 1 is connected to the feed pipe 3, and the feed pipe 3 is connected to an external feed conveying device;

[0024] It also includes a conveying pipe 4, a chassis 5, plow-shaped plates 6, and a power assembly; the sterilization cylinder 1 is fixedly connected to the conveying pipe 4, and the conveying pipe 4 is connected to an external steam generator; the conveying pipe 4 has several air outlets 401; the sterilization cylinder 1 is rotatably connected to the chassis 5, which is configured as an inverted frustum structure to guide the feed to move towards the discharge port 101; the chassis 5 is fixedly connected to three plow-shaped plates 6, and all the plow-shaped plates 6 are in contact with the sterilization cylinder 1; the sterilization cylinder 1 is connected to the power assembly, and the power assembly is connected to the chassis 5.

[0025] The power assembly includes a motor 111, a gear 112, and a gear ring 113; the sterilization cylinder 1 is bolted to the motor 111; the output shaft of the motor 111 is fixedly connected to the gear 112; the chassis 5 is fixedly connected to the gear ring 113, and the gear ring 113 meshes with the gear 112.

[0026] It also includes a diversion plate 114; the sterilization cylinder 1 is fixedly connected to the diversion plate 114; the diversion plate 114 is provided with a cavity 11401, and the cavity 11401 is connected to the delivery pipe 4; the cavity 11401 has a number of air outlets 11402.

[0027] It also includes airbags 121 and springs 122; eight airbags 121 are fixedly connected to the diversion plate 114; the diversion plate 114 has several through holes 11403; each airbag 121 has several channels 12101, and each channel 12101 is connected to the corresponding through hole 11403; each airbag 121 is fixedly connected to a spring 122.

[0028] It also includes a second motor 131, a rotating shaft 132, and a dispersing plate 133; the feed pipe 3 is bolted to the second motor 131; the feed pipe 3 is rotatably connected to the rotating shaft 132, and the rotating shaft 132 is fixedly connected to the output shaft of the second motor 131; the second motor 131 is fixedly connected to several dispersing plates 133 that are staggered, and the dispersing plates 133 are used to break up the clumps of feed.

[0029] During the feed sterilization process, the external conveying equipment first transports the feed into the sterilization cylinder 1 through the feed inlet pipe 3. Simultaneously, the external steam generator continuously supplies high-temperature steam into the sterilization cylinder 1 through the conveying pipe 4 and the air outlet 401, allowing the feed to undergo pre-sterilization during transport. When the feed in the sterilization cylinder 1 is about to submerge the top of the plowshare 6, the external conveying equipment stops transporting the feed. Then, the external steam generator continues to supply high-temperature steam into the conveying pipe 4 to achieve efficient sterilization of the feed. At the same time, the output shaft of the motor 111 drives the chassis 5 and the plowshare 6 to rotate sequentially through the gear 112 and gear ring 113, causing the plowshare 6 to continuously rotate. The feed at the bottom of the sterilization cylinder 1 is plowed upwards and guided to move upwards along its inclined surface. When the feed is lifted to the top of the plow-shaped plate 6, the feed is thrown into the upper space inside the sterilization cylinder 1 under the combined action of centrifugal force and gravity, due to the continuous rotation of the plow-shaped plate 6. This achieves uniform turning and circulation of the feed. In this way, the plow-shaped plate 6 makes the feed turn and circulate evenly in the sterilization cylinder 1, thereby increasing the contact area and contact efficiency between the feed and the high-temperature steam, thus enhancing the sterilization effect. This effectively avoids the problem that uneven gaps caused by feed accumulation prevent the high-temperature steam from quickly and evenly penetrating the entire feed layer, resulting in some areas not meeting the effective sterilization standards in terms of temperature and humidity.

[0030] After the feed sterilization process is completed, the feed collection box is first manually placed directly below the sterilization cylinder 1 to ensure that the feed falls accurately into the collection box during the discharge process. Then, the operator rotates handle 201 to rotate the sealing block 2, unscrewing it from the discharge port 101. This releases the blockage, allowing the feed inside the sterilization cylinder 1 to fall through the discharge port 101 into the collection box below under gravity. During the discharge process, to prevent feed accumulation and obstruction, [further steps are taken]. The output shaft of the motor 111 drives the plow plate 6 to rotate through the gear 112, gear ring 113 and chassis 5 in sequence. The plow plate 6 causes the feed to be evenly turned inside the sterilization cylinder 1, thereby effectively avoiding feed blockage or residue, and improving the discharge efficiency and thoroughness. In addition, by setting the chassis 5 as an inverted frustum structure, its inclined surface guides the feed to move towards the discharge port 101, further promoting the smooth flow of feed to the discharge port 101, reducing the possibility of dead corner accumulation, and improving the overall smoothness and uniformity of discharge.

[0031] To further enhance the pre-sterilization effect, a diversion plate 114 is added, with a cavity 11401 and a second air outlet 11402 on the diversion plate 114. The specific implementation is as follows: During the process of feed entering the sterilization cylinder 1 through the feed pipe 3, due to the diversion plate 114, cavity 11401, and second air outlet 11402, some of the high-temperature steam delivered to the conveying pipe 4 will flow into the sterilization cylinder 1 sequentially through the cavity 11401 and the second air outlet 11402. When the feed falls into the sterilization cylinder 1 through the feed pipe 3, it will first fall onto the diversion plate 114, then move downwards along the surface of the diversion plate 114, and finally pass through the sterilization cylinder 1 and the diversion plate. The feed falls downward through the gap between the distribution plate 114 and the sterilization cylinder 1. During this process, the feed is dispersed as it moves downward along the surface of the distribution plate 114, allowing the high-temperature steam flowing out from the outlet 11402 to better contact the feed. This ensures that the feed is pre-sterilized evenly, further enhancing the pre-sterilization effect. In addition, as the feed falls downward through the gap between the distribution plate 114 and the sterilization cylinder 1, it falls onto the plow-shaped plate 6 and moves downward along its surface. Under the action of the plow-shaped plate 6, the feed moves towards the conveying pipe 4, allowing it to contact the high-temperature steam flowing out from the outlet 401 more fully, further improving the pre-sterilization effect.

[0032] To further refine the feed dispersion process, the distribution plate 114 is also equipped with a through hole 11403, an air bladder 121, and a spring plate 122. Specifically, when the feed falls onto the distribution plate 114 through the feed pipe 3, some of the feed will fall onto the spring plate 122. Due to gravity, the feed will exert pressure on the air bladder 121 below, causing the air bladder 121 to release internal gas after being compressed. This gas flows through the corresponding through hole 11403 to the adjacent air bladder 121, causing it to expand and push the corresponding spring plate 122 upward, thereby ejecting the feed on the spring plate 122 into the air, making the feed more dispersed, thereby increasing the contact area between the feed and the high-temperature steam flowing out from the air outlet 401, and further enhancing the pre-sterilization effect.

[0033] Considering that when feed clumps together, it will be difficult to ensure the uniformity and thoroughness of sterilization.

[0034] Therefore, a second motor 131, a rotating shaft 132, and a dispersing plate 133 are added. During the process of the external conveying equipment conveying feed into the sterilization cylinder 1, the output shaft of the second motor 131 is controlled to drive the dispersing plate 133 to rotate through the rotating shaft 132. The rotating dispersing plate 133 breaks up the clumps of feed passing through the feed inlet pipe 3, so as to avoid the problem that the clumps of feed will make it difficult to ensure the uniformity and thoroughness of the sterilization effect.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
