[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Example 1:

[0035] This embodiment provides a method for enzymatic hydrolysis of feed compound microorganisms, including the following steps:

[0036] S1: Premix the feed base material pulverized to 20-40 mesh with the compound enzyme preparation at a mass ratio of 100:0.3-0.8 to obtain the premixed feed.

[0037] By controlling the mesh size of the feed base and the precise ratio with the compound enzyme preparation, a uniform and efficient material basis is provided for the subsequent enzymatic hydrolysis reaction, which helps to improve the enzymatic hydrolysis efficiency and product quality stability.

[0038] S2: The premixed material is continuously fed into the enzymatic hydrolysis equipment and enzymatically hydrolyzed for 15-30 minutes at 35-42℃ and dissolved oxygen value ≥2mg / L. The enzymatic hydrolysis reaction is carried out in the enzymatic hydrolysis equipment. The temperature is kept constant by the temperature control component and the dissolved oxygen value is kept ≥2mg / L by the atomizing spray component. The mixing mechanism in the enzymatic hydrolysis equipment is used for stirring, and mixing, heat transfer and mass transfer are achieved at the same time.

[0039] Enzymatic hydrolysis under constant temperature and oxygen conditions, accompanied by mechanical stirring, significantly improves the rate and thoroughness of the enzymatic hydrolysis reaction, enhances the release of nutrients, and at the same time, stirring ensures the uniformity and stability of the reaction system.

[0040] S3: After enzymatic hydrolysis is completed, the compound microbial liquid is added online to the enzymatic hydrolysis equipment through a metering pump, and acid or alkaline solution is added through a metering pump to adjust the pH of the system to 5.8-6.2. Fermentation continues for 2-4 hours. During the fermentation process, the mixing mechanism in the enzymatic hydrolysis equipment is used for stirring, which simultaneously achieves mixing, heat transfer and mass transfer.

[0041] It achieves seamless integration and automated control of enzymatic hydrolysis and fermentation processes in the same equipment. By precisely controlling the pH value and continuous stirring, it creates the best environment for microbial fermentation, thereby improving fermentation efficiency and product quality.

[0042] S4: After fermentation, the material is dried at low temperature until the moisture content is ≤12% to obtain the finished product. After steps S1-S4 are completed, the atomizing spray component of the enzymatic hydrolysis equipment is started. The cleaning agent and sterilization medium are sprayed through the side enzyme liquid atomizing nozzle to clean and sterilize the enzymatic hydrolysis equipment online.

[0043] Low-temperature drying effectively preserves heat-sensitive nutrients, resulting in a finished product that is easy to store. The equipment has online cleaning and sterilization functions, eliminating cross-contamination and ensuring hygiene, safety, and batch stability for continuous production.

[0044] In summary, by organically combining enzymatic hydrolysis and fermentation processes, and conducting enzymatic hydrolysis and microbial fermentation in stages under strict control of temperature, dissolved oxygen, and pH, the release rate and bioavailability of nutrients in feed are significantly improved. This method has advantages such as short reaction time, high efficiency, strong controllability of conditions, low moisture content of finished product, and easy storage. At the same time, the online cleaning and sterilization functions effectively avoid cross-contamination between batches, ensuring the hygiene and safety of feed, and are suitable for industrial continuous production.

[0045] Example 2:

[0046] This embodiment provides a feed compound microbial enzymatic hydrolysis device for implementing the above method, including a mounting frame 1, an upper fixing plate 2 and a lower fixing plate 3 fixedly mounted on the mounting frame 1, a crushing mechanism 4 provided on the top of the upper fixing plate 2, a conveying mechanism 5 provided between the upper fixing plate 2 and the lower fixing plate 3, and a mixing mechanism 6 provided on the conveying mechanism 5. The crushing mechanism 4 is used to crush the feed base material, the conveying mechanism 5 is used to enzymatically hydrolyze the premix, and after the enzymatic hydrolysis is completed, a compound microbial liquid is added to continue fermentation, and the mixing mechanism 6 is used to mix and stir the raw materials.

[0047] This enzymatic hydrolysis equipment integrates multiple functions such as crushing, mixing, enzymatic hydrolysis and fermentation. It has a compact structure and realizes fully automated and continuous production from raw material processing to fermentation output, which greatly improves production efficiency and space utilization.

[0048] The crushing mechanism 4 includes an outer mounting shell 41 and an inner mounting shell 42. The outer mounting shell 41 and the inner mounting shell 42 are fixedly connected by a bridge frame 44. A rotating rod 43 is rotatably mounted at the center of the inner mounting shell 42. A second motor 45 is fixedly mounted at the top of the inner mounting shell 42. The output end of the second motor 45 is fixedly connected to the top end of the rotating rod 43. A toothed roller 46 is fixedly mounted at the bottom end of the rotating rod 43. Teeth 47 are provided on the inner wall of the outer mounting shell 41.

[0049] The crushing mechanism 4 adopts a design that combines toothed rollers 46 and teeth 47, resulting in high crushing efficiency. By controlling the gap between toothed rollers 46 and teeth 47, the feed base material can be effectively crushed to the target particle size, providing suitable material particle size conditions for subsequent enzymatic hydrolysis reactions.

[0050] The upper fixed plate 2 has a motor 21 and a metering pump 22 fixedly installed on its top, and the lower fixed plate 3 has an electrically controlled opening and closing cover 31.

[0051] Motor 21 provides power to conveying mechanism 5, metering pump 22 enables precise quantitative addition of bacterial solution and pH adjuster, and electrically controlled opening and closing cover 31 enables automatic discharge of product, improving the automation level and control accuracy of the equipment.

[0052] The conveying mechanism 5 includes a rotating shaft 51 and a rotating ring 52. The rotating shaft 51 is rotatably mounted between the upper fixed plate 2 and the lower fixed plate 3. The output end of the motor 21 is fixedly connected to the top of the rotating shaft 51. The rotating shaft 51 and the rotating ring 52 are fixedly connected by a partition plate 53. Five partition plates 53 are evenly arranged. The area between two adjacent partition plates 53 is the transport area. Temperature control components 54 are arranged on both sides of the partition plate 53. Atomizing spray components 55 are arranged on the rotating ring 52. Five atomizing spray components 55 are arranged corresponding to the transport area. The temperature control components 54 are existing electric heating technology, and the atomizing spray components 55 are existing microporous aeration technology, which will not be described in detail here.

[0053] The conveying mechanism 5 achieves zoned processing and continuous flow of materials by dividing them into five transport zones, thereby improving processing capacity. The temperature control component 54 can precisely control the temperature of each zone, and the atomizing spray component 55 can precisely control the dissolved oxygen in each zone through microporous aeration, ensuring the optimal reaction environment for the enzymatic hydrolysis and fermentation process. In addition, the atomizing spray component 55 can also spray cleaning agents and sterilization media laterally, and atomize the cleaning agents and sterilization media into tiny droplets for online cleaning and sterilization of the enzymatic hydrolysis equipment.

[0054] The mixing mechanism 6 has five components corresponding to the transport area. The mixing mechanism 6 includes a receiving frame 61, a positioning rod 62, a first connecting rod 65, a second connecting rod 66, and a third connecting rod 67. The positioning rod 62 is rotatably installed in the transport area. A stirring blade 63 is fixedly installed on the surface of the positioning rod 62. One end of the positioning rod 62 extends to the outside of the rotating ring 52. The receiving frame 61 is fixedly installed on the outside of the rotating ring 52. A transmission shaft 611 is rotatably installed on the receiving frame 61. A gear 64 is fixedly connected to the surface of the transmission shaft 611. A gear ring 32 is fixedly installed on the top of the lower fixed plate 3. The gear ring 32 meshes with the gear 64. One end of the first connecting rod 65 is fixedly connected to the surface of the transmission shaft 611. The other end of the first connecting rod 65 is hinged to one end of the second connecting rod 66. The other end of the second connecting rod 66 is hinged to one end of the third connecting rod 67. The other end of the third connecting rod 67 is fixedly connected to the surface of the positioning rod 62.

[0055] The mixing mechanism 6, through the meshing of gear 64 and fixed gear ring 32, and in conjunction with the linkage structure, generates rotation while revolving, driving the stirring blade 63 to achieve reciprocating stirring of complex trajectories, which greatly enhances the mixing uniformity, heat transfer and mass transfer efficiency of the materials, and ensures the sufficiency and consistency of the reaction.

[0056] In use, motor 25 drives toothed roller 46 to rotate around the axis of rotating rod 43. Feed base and compound enzyme preparation are fed in from the top of outer mounting shell 41, and the mass ratio of feed base to compound enzyme preparation is controlled to be 100:0.3-0.8. When the feed base passes between toothed roller 46 and teeth 47, the feed base is crushed to 20-40 mesh. The crushed feed base and compound enzyme preparation enter the conveying area together. Motor 21 drives the conveying mechanism 5 to rotate around the axis of rotating shaft 51 through rotating shaft 51. During the rotation of conveying mechanism 5, feed base and compound enzyme preparation with a preset mass ratio are input into each conveying area.

[0057] During this process, the temperature control component 54 maintains a constant temperature of 35-42℃ in each transport zone, and the atomizing spray component 55 maintains a dissolved oxygen value of ≥2mg / L in each transport zone through aeration. While the conveying mechanism 5 rotates, the mixing mechanism 6 rotates synchronously around the axis of the rotating shaft 51. The gear 64 moves along the gear ring 32 and drives the transmission shaft 611 to rotate synchronously around its own axis. The transmission shaft 611 rotates and drives the first connecting rod 65 to rotate synchronously around the axis of the transmission shaft 611. The first connecting rod 65 rotates and drives the positioning rod 62 to rotate synchronously around its own axis through the second connecting rod 66 and the third connecting rod 67. The positioning rod 62 rotates and drives the stirring blade 63 to rotate synchronously around the axis of the positioning rod 62. Accompanying the movement of the gear 64 along the gear ring 32, the stirring blade 63 rotates back and forth around the axis of the positioning rod 62, realizing the uniform mixing, heat transfer and mass transfer of the feed base and the compound enzyme preparation, and carrying out the enzymatic reaction.

[0058] After 15-30 minutes of enzymatic hydrolysis, when the transport zone passes the bottom of the metering pump 22, the metering pump 22 adds compound microbial liquid to the transport zone, and adds acid or alkali solution through the metering pump to adjust the pH of the system to 5.8-6.2. Fermentation continues for 2-4 hours. During the fermentation process, the mixing mechanism 6 continues to rotate around the axis of the rotating shaft 51. Similarly, the stirring blade 63 rotates back and forth around the axis of the positioning rod 62 to further realize the mixing, heat transfer and mass transfer of materials.

[0059] After fermentation, the electrically controlled opening and closing cover 31 is opened, and the material is discharged into the low-temperature drying equipment as it passes through the electrically controlled opening and closing cover 31. After low-temperature drying to a moisture content of ≤12%, the finished product is obtained. At the same time, the atomizing spray component 55 of the enzymatic hydrolysis equipment is activated. The cleaning agent and sterilization medium are sprayed laterally through the atomizing spray component 55 to clean and sterilize the enzymatic hydrolysis equipment online. The waste liquid after cleaning can be discharged out through the electrically controlled opening and closing cover 31.

[0060] In summary, the equipment integrates multiple functions such as crushing, mixing, enzymatic hydrolysis, and fermentation into one compact structure. Its continuous and automated operation significantly improves production efficiency. The coordinated design of the conveying and mixing mechanisms ensures uniform mixing, efficient mass and heat transfer of materials within the transport zone, guaranteeing stable enzymatic hydrolysis and fermentation processes. The combined use of atomizing spray components and temperature control components precisely controls the reaction environment, further enhancing product quality. Furthermore, the equipment features online cleaning and sterilization functions, reducing manual intervention and lowering the risk of contamination, thus meeting the hygiene and environmental protection requirements of modern feed production.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
