Description

Technical Field

[0001] This invention belongs to the field of soybean meal enzymatic hydrolysis, specifically a soybean meal low-moisture enzymatic hydrolysis device and its enzymatic hydrolysis process. Background Technology

[0002] Improving the application of soybean protein in the nutrition of young animals has always been a hot topic in feed research, which will greatly reduce feed and breeding costs. Soybean protein contains high levels of anti-nutritional factors, such as urease, trypsin inhibitors, glycinin, β-conglycinin, and raffinose, which significantly limit its application in the nutrition of young animals. By combining enzymatic hydrolysis with hydrothermal two-phase processing, the utilization rate and available energy value of soybean protein can be improved, as well as the hygiene and palatability of the feed.

[0003] Key equipment for enzymatic hydrolysis includes an automatic micro-enzyme addition system, a dry powder-liquid addition mixing and heat preservation equipment, a three-dimensional enzymatic hydrolysis and automatic discharge tank, a wet powder low-residue transmission system, and a distributed control system for enzymatic hydrolysis process parameters. Soybean meal undergoes enzymatic hydrolysis in a mixer. During enzymatic hydrolysis, an aqueous solution of enzyme preparation needs to be added. However, the environmental conditions for enzyme preparation to function are specific. If the mixture is directly opened during the enzymatic hydrolysis process, it is easy to disrupt the enzymatic hydrolysis environment inside the mixer, resulting in enzymatic hydrolysis failure.

[0004] In summary, the present invention provides a low-moisture enzymatic hydrolysis device for soybean meal and its enzymatic hydrolysis process to solve the above-mentioned problems. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a low-moisture enzymatic hydrolysis device for soybean meal and its enzymatic hydrolysis process. This solves the problems in the prior art where adding ingredients directly to the mixer during the enzymatic hydrolysis process can easily disrupt the enzymatic hydrolysis environment within the mixer, leading to enzymatic hydrolysis failure.

[0006] A low-moisture enzymatic hydrolysis device for soybean meal includes a wet powder constant-temperature mixer. The wet powder constant-temperature mixer contains an enzymatic hydrolysis chamber. An organic cover is installed on the top of the wet powder constant-temperature mixer. A preparation cylinder is installed on the wet powder constant-temperature mixer. A feeding hopper is fixedly connected to the bottom of the preparation cylinder. The bottom opening of the feeding hopper is connected to the wet powder constant-temperature mixer via a reagent delivery pipe. The reagent delivery pipe connects the feeding hopper to the inside of the wet powder constant-temperature mixer. A sealing device is installed inside the feeding hopper. The sealing plug has its outer wall in contact with the inner wall of the hopper. A spring push rod is installed on the top of the sealing plug, and a push rod sleeve is movably sleeved at one end of the spring push rod. A cylinder cover is installed at the opening of the preparation cylinder, and the push rod sleeve is installed at the bottom of the cylinder cover. An airbag frame is installed on one end of the drug delivery pipe near the hopper, and an airbag is installed on the airbag frame. An inflation tube is connected to the bottom of the airbag, and one end of the inflation tube passes through the drug delivery pipe and extends to the outside.

[0007] Furthermore, the formulation cylinder is connected to the inner part of the feeding hopper, and a reinforcing seat is fixedly connected to the surface of the feeding hopper. The reinforcing seat is installed on the side wall of the wet powder constant temperature mixer through a reinforcing frame.

[0008] Furthermore, the hopper has a conical structure, the sealing plug matches the shape of the inner wall of the hopper, and multiple sealing silicone rings are installed on the outer wall of the sealing plug.

[0009] Furthermore, a feed pipe is installed on the cylinder cover, and the inlet of the feed pipe is connected to the inside of the formulation cylinder.

[0010] Furthermore, the bottom of the sealing plug is provided with an airbag groove, one end of the airbag is installed on the airbag frame, and the other end of the airbag is fixedly connected in the airbag groove. The airbag is folded with a corrugated structure.

[0011] Furthermore, the airbag frame is installed on the side wall of the drug delivery pipe, and the airbag frame has a leakage port.

[0012] Furthermore, one end of the spring push rod is movably inserted into the push rod sleeve and fixedly connected to a limit ring. The limit ring is connected to the top of the push rod sleeve by a compression spring, which is disposed inside the push rod sleeve.

[0013] An enzymatic hydrolysis process using a low-moisture soybean meal enzymatic hydrolysis device includes the following steps: Step 1: Using a mobile guide car, add the soybean meal powder to be enzymatically hydrolyzed into the wet powder constant temperature mixer, and then pulverize it inside the wet powder constant temperature mixer; Step 2: Prepare the aqueous solution of the enzyme preparation. Add the aqueous solution of the enzyme preparation into the preparation cylinder. The amount added should match the processing amount of soybean meal powder in the wet powder constant temperature mixer. Inflate the air bag through the air inflator. Then the air bag inflates and pushes the sealing plug upward. The sealing plug is compressed by the spring push rod. The sealing silicone ring of the sealing plug moves away from the inner wall of the feeding hopper. The opening of the feeding hopper is opened. The enzyme preparation flows into the agent delivery pipe through the feeding hopper and then into the wet powder constant temperature mixer. It is mixed and kept warm with the soybean meal powder in the wet powder constant temperature mixer. Step 3: After incubation and enzymatic hydrolysis, the product undergoes drying using a dual-channel, all-around steam drying method to reduce moisture content. Step 4: The dried enzymatically hydrolyzed soybean meal is pulverized a second time, screened, and then put into the packaging system for storage and packaging.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention connects an independent formulation cylinder to a constant-temperature mixer for wet powder materials. A pressure bag is inflated to push the sealing plug upwards, enabling quantitative dispensing of the enzyme preparation. The sealing silicone ring on the outer wall of the sealing plug maintains close contact with the inner wall of the hopper, ensuring the airtightness of the enzymatic hydrolysis chamber when not in use. This effectively prevents external environmental interference with the enzymatic hydrolysis process and adds an interface for uniformly mixing soybean meal powder and enzyme aqueous solution. Furthermore, considering the environmental conditions for enzyme activity, an automatic internal temperature control system for the mixer is incorporated directly into the equipment design and manufacturing process. A green, environmentally friendly, and highly efficient steam insulation system ensures the reliability of the enzymatic hydrolysis process. 2. This invention utilizes the elastic reset structure of a spring push rod and a compression spring. After inflation stops, the sealing plug can automatically move down and reset, resealing the feeding hopper. This achieves precise control of enzyme addition and stable maintenance of the enzymatic hydrolysis environment, solving the problem of directly opening the lid and adding enzymes during traditional enzymatic hydrolysis, which disrupts the enzymatic hydrolysis environment. This significantly improves the efficiency of soybean meal enzymatic hydrolysis and the quality of the product.

[0015] 3. This invention employs a dual-channel, all-around steam drying enzymatic hydrolysis process, rapidly reducing material moisture after heat preservation and enzymatic hydrolysis. This avoids the problems of localized overheating or moisture residue caused by traditional drying methods. Simultaneously, combined with secondary crushing and screening processes, it ensures the uniformity of particle size in the enzymatically hydrolyzed soybean meal, improving the mixing effect in subsequent feed processing. Automated addition of soybean meal powder is achieved through a mobile guide car, coupled with a precise dosing structure using a formulation cylinder and reagent delivery pipe, forming a continuous enzymatic hydrolysis production process. This eliminates the need for traditional scraper transport, avoiding material contamination during transportation. The automated mobile guide car reciprocates, transporting the wet material from the constant-temperature mixer to the enzymatic hydrolysis chamber. This avoids the accumulation of moisture inside the scraper and the microbial risks associated with material residue, greatly facilitating the cleanliness and efficient operation of the production line.
