Description

Technical Field

[0001] The present invention relates to the technical field of feed production, and in particular to feed fermentation equipment and a fermentation method. Background Art

[0002] Feed fermentation is a technical means to improve feed quality and nutritional value by treating feed raw materials through the action of microorganisms. In the process of feed fermentation production, the quality of feed fermentation is not only affected by conditions such as temperature, humidity, and oxygen supply, but also whether the feed raw materials can be evenly mixed with fermentation liquid or water is an important influencing factor. However, traditional fermentation equipment lacks an effective material dispersion and mixing mechanism, and a large amount of material is prone to accumulation when loading. For example, the common loading method is to transport the material to the fermentation container through a simple conveyor belt or screw conveyor. In this process, the material often enters in a concentrated state and cannot be evenly distributed.

[0003] This uneven mixing of materials will cause a series of problems. First, the fermentation process is difficult to proceed synchronously. Materials piled in different locations have inconsistent fermentation progress due to factors such as uneven microbial contact, differences in oxygen supply, and uneven temperature distribution. Some materials may over-ferment, produce bad odors or lose nutrients, while other materials are not fermented completely, failing to give full play to the advantages of fermented feed in improving nutritional value and palatability. Secondly, uneven fermentation will also lead to unstable quality of the final product, which cannot meet the requirements of the livestock industry for standardized, high-quality feed, and affect the growth performance and health of animals.

[0014] The present invention also proposes a feed fermentation method, using a feed fermentation device, comprising the following steps: S1. Use a material conveyor to deliver the feed premix into the temporary storage chamber. After the feed premix accumulates in the temporary storage chamber, the first elastic member is compressed, and the partition plate slides toward the fermentation chamber. After the feed premix falls into the fermentation chamber, the partition plate is reset, and the material conveyor continues to deliver the feed until the feed premix in the fermentation chamber meets the fermentation demand; S2. The stirring element rotates continuously during the material conveying process, so that the feed premix is ​​initially dispersed in the temporary storage chamber and the feed premix in the fermentation chamber is stirred at the same time; S3, when the feed premix is ​​continuously fed into the fermentation chamber, bacterial liquid and clean water are simultaneously fed into the fermentation chamber; S4. After the feed premix is ​​delivered, the mixture in the fermentation chamber is stirred for 10-15 minutes and then left to ferment for 3-12 hours at a temperature of 25°C-35°C.

[0015] The working principle and beneficial effects of the present invention are: In the present invention, in order to solve the problem of the fermentation quality being affected by the accumulation of materials during feed fermentation in the related art, the fermentation cylinder is divided into a temporary storage chamber and a fermentation chamber by a partition plate. When the feed premix is ​​put into the temporary storage chamber, as the materials accumulate, the partition plate slides downward under the pressure of the material gravity, compresses the first elastic member, so that the temporary storage chamber is connected with the fermentation chamber, and the materials fall into the fermentation chamber; when the materials in the temporary storage chamber are reduced, the first elastic member restores the partition plate to slide upward, and the two chambers are separated again. At this time, as the stirring member rotates, the materials in the temporary storage chamber and the fermentation chamber are dispersed and stirred at the same time, and clean water and fermentation stock solution are added to the fermentation chamber while stirring, so that the feed premix entering the fermentation chamber in stages can be evenly mixed with the clean water and the fermentation stock solution, thereby improving the fermentation quality and avoiding the phenomenon of excessive or incomplete fermentation of some feeds due to uneven mixing. When the feed premix is ​​temporarily stored in the temporary storage chamber, it will also be dispersed as the partition plate rotates, which can make the transported feed loose in advance, and further improve the uniformity of the mixing of the feed premix, clean water and fermentation stock solution.

[0016] The cooperation between the partition plate and the stirring member can effectively distinguish the temporary storage and fermentation process of the feed premix in different chambers of the same equipment, which is conducive to the orderly management of the fermentation process. For example, the material can be preliminarily inspected for quality or simply pre-dispersed in the temporary storage chamber without affecting the ongoing fermentation process in the fermentation chamber. The sliding connection between the partition plate and the stirring member and the setting of the first elastic member enable the transfer of the material to be automatically controlled according to the amount of material in the temporary storage chamber, without the need for additional complex control mechanisms, thereby reducing equipment costs and failure rates.

DETAILED DESCRIPTION In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0020] In order to simplify the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0021] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, proposes a feed fermentation equipment, including a fermentation cylinder 1; a stirring member 2 is rotatably arranged in the fermentation cylinder 1; a partition plate 3 is slidably arranged on the stirring member 2, and the fermentation cylinder 1 is divided into a temporary storage chamber 101 and a fermentation chamber 102. After the partition plate 3 slides, the temporary storage chamber 101 is connected to the fermentation chamber 102 or the connection is cancelled; the two ends of the first elastic member 4 act on the partition plate 3 and the stirring member 2 respectively, and are used to provide a force for resetting the partition plate 3.

[0024] In this embodiment, the partition plate 3 separates the fermentation cylinder 1 into a temporary storage chamber 101 and a fermentation chamber 102. When the feed premix is ​​added into the temporary storage chamber 101, as the material accumulates, the partition plate 3 slides downward under the pressure of the material gravity, compressing the first elastic member 4, so that the temporary storage chamber 101 is connected with the fermentation chamber 102, and the material falls into the fermentation chamber 102; when the material in the temporary storage chamber 101 is reduced, the restoring force of the first elastic member 4 causes the partition plate 3 to slide upward and re-separate the two chambers. At this time, as the stirring member 2 rotates, the materials in the temporary storage chamber 101 and the fermentation chamber 102 are dispersed and stirred at the same time, and clean water and fermentation stock solution are added to the fermentation chamber 102 while stirring, so that the feed premix entering the fermentation chamber 102 in stages can be evenly mixed with the clean water and the fermentation stock solution, thereby improving the quality of fermentation and avoiding the phenomenon of excessive or incomplete fermentation of some feeds due to uneven mixing. When the feed premix is ​​temporarily stored in the temporary storage chamber 101 , it will also be dispersed as the partition plate 3 rotates, so that the delivered feed can be loosened in advance, further improving the uniformity of the mixing of the feed premix, clean water and fermentation stock solution.

[0025] The cooperation between the partition plate 3 and the stirring member 2 can effectively distinguish the temporary storage and fermentation process of the feed premix in different chambers of the same device, which is conducive to the orderly management of the fermentation process. For example, the material can be preliminarily inspected for quality or simply pre-dispersed in the temporary storage chamber 101 without affecting the ongoing fermentation process in the fermentation chamber 102. The sliding connection between the partition plate 3 and the stirring member 2 and the setting of the first elastic member 4 enable the transfer of the material to be automatically controlled according to the amount of material in the temporary storage chamber 101, without the need for an additional complex control mechanism, thereby reducing the equipment cost and failure rate.

[0026] Furthermore, the stirring member 2 includes a stirring shaft 21, which is rotatably arranged in the fermentation cylinder 1, and the partition plate 3 is slidably arranged on the stirring shaft 21; the limiting plate 22 is arranged on the stirring shaft 21, and one end of the first elastic member 4 acts on the limiting plate 22; the stirring rod 23 is arranged on the limiting plate 22.

[0027] In this embodiment, the stirring shaft 21 of the stirring member 2 is a hollow shaft made of high-strength alloy steel to ensure stable rotation. The limiting plate 22 is fixed to the middle position of the stirring shaft 21 by welding. It is circular in shape, has a certain thickness and a conical upper surface. It is supportive and convenient for the partition plate 3 to slide downward, so that the feed premix can quickly slide into the fermentation chamber 102. There are multiple stirring rods 23, which are evenly welded on the edge of the limiting plate 22 so that the material can be turned over better during stirring. One end of the first elastic member 4 is against the upper surface of the limiting plate 22, and the other end is connected to the corresponding position of the partition plate 3. When the equipment is running, the stirring shaft 21 drives the limiting plate 22 and the stirring rod 23 to rotate, and the material in the fermentation chamber 102 is stirred. At the same time, the partition plate 3 slides on the stirring shaft 21 according to the weight of the feed premix to adjust the connection state between the temporary storage chamber 101 and the fermentation chamber 102.

[0028] This connection mode of the stirring member 2 and the partition plate 3 makes the overall structure of the equipment more compact. It can realize the integration of multiple functions in a limited space, and is suitable for feed production sites of different sizes. Whether it is a large feed production plant or a small farm, it can be easily installed and used, which improves the versatility and adaptability of the equipment.

[0029] Furthermore, the stirring shaft 21 has a liquid inlet channel 211, and also includes a first support portion 51, which is arranged on the limiting disk 22, and there are multiple first support portions 51, and the multiple first support portions 51 are distributed circumferentially at intervals on the limiting disk 22; there are multiple nozzles 52, and the multiple nozzles 52 are arranged on the first support portion 51, and the nozzles 52 are all connected to the liquid inlet channel 211.

[0030] Furthermore, it also includes a liquid inlet pipe 53, which is arranged on the fermentation cylinder 1; a support tube 54 is arranged on the fermentation cylinder 1, and one end is connected to the liquid inlet pipe 53; a liquid inlet ring 55 is sleeved on the stirring shaft 21, and the liquid inlet channel 211 and the support tube 54 are both connected to the liquid inlet ring 55.

[0031] In this embodiment, the liquid inlet pipe 53 is connected from the top of the fermentation cylinder 1 and connected to one end of the support pipe 54. The support pipe 54 extends downward along the fermentation cylinder 1 and is connected to the liquid inlet ring 55. The liquid inlet ring 55 is sleeved on the upper part of the stirring shaft 21 and does not rotate with the stirring shaft 21. An annular flow channel is arranged inside. The flow channel and the liquid inlet channel 211 of the stirring shaft 21 and the connection port of the support pipe 54 are all sealed to prevent liquid leakage. During the rotation of the stirring shaft 21, it can maintain constant communication with the liquid inlet channel 211. During the fermentation process, when it is necessary to add bacterial liquid or clean water to the fermentation chamber 102, the liquid enters the liquid inlet channel 211 of the stirring shaft 21 through the liquid inlet pipe 53, the support pipe 54, and the liquid inlet ring 55, and is finally sprayed out from the nozzle 52 in an atomized form and evenly sprinkled on the material in the fermentation chamber 102. As the partition plate 3 slides, the feed premix enters the fermentation chamber 102 in batches. Each time the feed premix enters the fermentation chamber 102, it is sprayed with bacterial liquid or clean water, thereby improving the mixing efficiency of the feed premix, bacterial liquid and clean water.

[0032] The design of the nozzle 52 and the liquid inlet system can realize uniform spraying of the liquid, avoid the situation of too much or too little liquid in some parts, so that the microorganisms can be evenly exposed to nutrients and water during the fermentation process, improve the fermentation quality, and ensure the consistency and stability of each batch of feed fermentation. The pipeline layout of the liquid inlet system is reasonable, and the stirring shaft 21 is used as part of the liquid transmission, which reduces the additional pipeline layout space and makes the internal structure of the equipment more concise. At the same time, it also reduces the resistance and leakage risk of the liquid during the transportation process, improves the reliability and safety of the equipment operation, and reduces the equipment maintenance cost.

[0033] Furthermore, the fermentation cylinder 1 has a first cylinder body 11 and a second cylinder body 12, the first cylinder body 11 is located above the second cylinder body 12, the diameter of the first cylinder body 11 is smaller than the diameter of the second cylinder body 12, the temporary storage chamber 101 is located in the first cylinder body 11, and the fermentation chamber 102 is located in the second cylinder body 12.

[0034] In this embodiment, the first barrel 11 and the second barrel 12 of the fermentation barrel 1 are manufactured in sections and then welded. The height of the first barrel 11 is about one-third of the height of the entire fermentation barrel 1, and its diameter is relatively small. The height of the second barrel 12 accounts for two-thirds of the height of the fermentation barrel 1, and its diameter is larger, providing sufficient space for fermentation. During assembly, the stirring member 2 is installed at the center of the fermentation barrel 1, and the partition plate 3 is installed at the corresponding height position on the stirring member 2, so that the temporary storage chamber 101 and the fermentation chamber 102 are respectively located in the first barrel 11 and the second barrel 12. During the feed fermentation process, the feed premix is ​​first temporarily stored in the temporary storage chamber 101, and then falls into the fermentation chamber 102 for fermentation reaction.

[0035] This diameter and height ratio design of the first cylinder 11 and the second cylinder 12 reasonably allocates the space of the temporary storage chamber 101 and the fermentation chamber 102. The smaller temporary storage chamber 101 can meet the temporary storage needs of materials without taking up too much space, while the larger fermentation chamber 102 provides sufficient space for the fermentation process, which is conducive to the growth and reproduction of microorganisms and the full progress of the fermentation reaction, thereby improving the fermentation efficiency and feed production. The difference in diameter between the first cylinder 11 and the second cylinder 12 makes it convenient for the feed premix to slide into the fermentation chamber 102 after the partition plate 3 slides downward, thereby ensuring the continuity of material transfer, improving the operating efficiency of the equipment, and reducing the cost increase caused by production interruptions.

[0036] Furthermore, there are a plurality of stirring rods 23 , and the plurality of stirring rods 23 are spaced apart from the plurality of first supporting portions 51 .

[0037] In this embodiment, the stirring rods 23 are evenly distributed on the edge of the limiting plate 22. The first support portion 51 and the stirring rods 23 are staggered, so that during the stirring process, the stirring rods 23 mainly turn over and stir the materials, and the nozzles 52 on the first support portion 51 will not be blocked too much by the stirring rods 23 when spraying liquid. When the equipment is running, the stirring shaft 21 drives the stirring rods 23 and the first support portion 51 to rotate synchronously, and the stirring rods 23 stir the materials in the fermentation chamber 102 evenly, and the nozzles 52 spray the bacterial liquid and clean water into the fermentation chamber 102, so that the liquid is evenly mixed with the materials.

[0038] The spacing distribution design of the stirring rod 23 and the first support part 51 improves the stirring and spraying effect. In the fermentation chamber 102, the turning of the stirring rod 23 can make the material form different layers and flow states, and the multi-angle spraying of the nozzle 52 can better cover these material layers, ensure the full contact and mixing of the liquid and the material, further improve the fermentation quality, reduce the feed quality differences caused by uneven fermentation, and improve the market competitiveness of the product. This distribution method can also reduce the mutual interference between the stirring rod 23 and the nozzle 52, and reduce the noise and wear during the operation of the equipment.

[0039] Furthermore, the second cylinder 12 has a discharge port 121 at the bottom, and also includes a discharge cylinder 6, which is rotatably arranged at the bottom of the first cylinder 11 and is located outside the first cylinder 11. The side wall of the first cylinder 11 has a first inlet 61 and a first outlet 62, and the first inlet 61 is connected to the first outlet 62. After the discharge cylinder 6 rotates, the discharge port 121 is connected to the first inlet 61 or abuts against the side wall of the discharge cylinder 6; one end of the discharge plate 7 is swingably arranged on the stirring rod 23, and the other end is used to abut against the bottom wall of the first cylinder 11 or stay away from the bottom wall.

[0040] In this embodiment, the discharge port 121 at the bottom of the second cylinder 12 is a long strip opening distributed along the radial direction of the second cylinder 12. The discharge barrel 6 is a hollow cylinder, which is mounted on the bracket at the bottom of the first cylinder 11 through a bearing and can rotate around its own axis. One end of the discharge plate 7 is connected to the end of the stirring rod 23 through a hinge, and the other end can contact or separate from the bottom wall of the first cylinder 11 during the rotation of the stirring rod 23. After the fermentation is completed, the discharge barrel 6 is rotated to align the discharge port 121 with the first inlet 61, and then the stirring member 2 is started, and the stirring rod 23 drives the discharge plate 7 to rotate. At this time, the discharge plate 7 is in contact with the stirring rod 23, and the feed in the fermentation chamber 102 can be scraped to the discharge port 121. The fermented feed in the fermentation chamber 102 is discharged from the discharge port 121 through the first inlet 61 and the first outlet 62. During the fermentation process, the stirring member 2 rotates in the reverse direction. At this time, the discharge plate 7 swings in the reverse direction under the resistance of the feed and does not abut against the bottom wall of the second cylinder 12, thereby reducing the resistance during the stirring process.

[0041] The design of the discharge barrel 6, the first inlet 61 and the first outlet 62 realizes the control of the discharge. The timing and speed of the discharge can be flexibly controlled as needed, and the fermented feed can be conveniently discharged from the equipment without affecting the fermentation process, thereby improving the operation convenience and production efficiency of the equipment.

[0042] The connection mode between the discharge plate 7 and the stirring rod 23 makes the discharge process smoother. Driven by the stirring rod 23, the discharge plate 7 can effectively scrape the material at the bottom of the fermentation chamber 102 and push it to the discharge port 121, avoiding the material from remaining at the bottom of the fermentation chamber 102, improving the discharge rate of the feed, reducing material waste, and reducing production costs.

[0043] Furthermore, it also includes a first material moving rod 8 , and there are multiple first material moving rods 8 , which are arranged on the inner wall of the first cylinder 11 .

[0044] In this embodiment, the first material-moving rod 8 is fixed to the inner wall of the first cylinder 11 by welding, and is evenly distributed along the circumferential direction of the inner wall. After the feed premix enters the temporary storage chamber 101, when the stirring member 2 rotates, the feed premix accumulates on the partition plate 3, so the first material-moving rod 8 is used to move the material in the temporary storage chamber 101, so that the material is more evenly distributed in the temporary storage chamber 101, and the material is prevented from accumulating in a local area.

[0045] Furthermore, the stirring rod 23 includes a second supporting portion 231, which is arranged on the limiting plate 22; there are multiple second material shifting rods 232, and the multiple second material shifting rods 232 are arranged at intervals on the second supporting portion 231, and the discharge plate 7 is swingably arranged on the second material shifting rod 232; the sliding rod 233 is slidingly arranged on one end of the second material shifting rod 232 close to the bottom wall; the two ends of the second elastic member 234 act on the second material shifting rod 232 and the sliding rod 233 respectively.

[0046] In this embodiment, there are multiple second material-moving rods 232, which are vertically welded on the second support part 231. The sliding rod 233 is a cylindrical metal rod, whose diameter is slightly smaller than the inner diameter of the bottom of the second material-moving rod 232, and is connected to the bottom of the second material-moving rod 232 through the second elastic member 234. During the stirring process, when the stirring rod 23 rotates, the second material-moving rod 232 and the sliding rod 233 stir the material in the fermentation chamber 102. When the sliding rod 233 encounters a large resistance, the second elastic member 234 will be compressed, causing the sliding rod 233 to shrink upward to avoid damage to the equipment. When the resistance disappears, the second elastic member 234 returns to its original state, and the sliding rod 233 falls again to participate in the stirring.

[0047] The design of the sliding rod 233 and the second elastic member 234 provides a certain buffer protection. In the fermentation feed production process, material agglomeration may occur. This structure can prevent the stirring rod 23 from being damaged due to forced stirring, extend the service life of the stirring member 2, and reduce the equipment maintenance cost.

[0048] As a second embodiment of the present invention, a feed fermentation method is proposed, using a feed fermentation device, comprising the following steps: S1. Use a material conveyor to deliver the feed premix into the temporary storage chamber 101. After the feed premix accumulates in the temporary storage chamber 101, the first elastic member 4 is compressed, and the partition plate 3 slides toward the fermentation chamber 102. After the feed premix falls into the fermentation chamber 102, the partition plate 3 is reset, and the material conveyor continues to deliver the feed until the feed premix in the fermentation chamber 102 meets the fermentation demand; S2, the stirring element 2 rotates continuously during the material conveying process, so that the feed premix is ​​initially dispersed in the temporary storage chamber 101, and the feed premix in the fermentation chamber 102 is stirred at the same time; S3, while the feed premix is ​​continuously fed into the fermentation chamber 102, bacterial liquid and clean water are simultaneously fed into the fermentation chamber 102; S4. After the feed premix is ​​delivered, the mixture in the fermentation chamber 102 is stirred for 10-15 minutes and then left to ferment for 3-12 hours at a temperature of 25° C.-35° C. After fermentation, the desired feed can be obtained.

[0049] In this embodiment, when the feed premix is ​​put into the temporary storage chamber 101, as the material accumulates, the partition plate 3 slides downward under the pressure of the material gravity, compressing the first elastic member 4, so that the temporary storage chamber 101 is connected with the fermentation chamber 102, and the material falls into the fermentation chamber 102; when the material in the temporary storage chamber 101 is reduced, the restoring force of the first elastic member 4 causes the partition plate 3 to slide upward and re-separate the two chambers. At this time, as the stirring member 2 rotates, the materials in the temporary storage chamber 101 and the fermentation chamber 102 are dispersed and stirred at the same time, and clean water and fermentation stock solution are added to the fermentation chamber 102 while stirring, so that the feed premix entering the fermentation chamber 102 in stages can be evenly mixed with the clean water and the fermentation stock solution, thereby improving the quality of fermentation and avoiding the phenomenon of excessive or incomplete fermentation of some feeds due to uneven mixing. When the feed premix is ​​temporarily stored in the temporary storage chamber 101, it will also be dispersed as the partition plate 3 rotates, which can make the transported feed loose in advance, and further improve the uniformity of the mixing of the feed premix, clean water and fermentation stock solution.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
