Description

Technical Field

[0001] The invention relates to the technical field of fermentation equipment, and in particular to fermentation equipment and a method for preparing low-phytic acid wheat bran by fermenting Hericium erinaceus. Background Art

[0002] Low-phytic acid wheat bran refers to wheat bran with reduced phytic acid content through specific technologies or methods. Microorganisms are used to ferment wheat bran. During their growth and metabolism, microorganisms produce phytase, which can decompose phytic acid, thereby reducing the phytic acid content and producing beneficial metabolites. After the phytic acid content is reduced, mineral elements such as calcium, iron, and zinc in the wheat bran are more easily absorbed and utilized by the human body or animals, reducing the antagonistic effect of phytic acid on mineral absorption and improving the nutritional quality of the wheat bran. Fermentation equipment usually uses a fermentation tank, which is usually cylindrical and equipped with a stirring device inside to fully mix the wheat bran with the fermentation bacteria and nutrients to ensure uniform fermentation. In existing fermentation equipment, rotating plates are usually used to stir and mix the materials in the fermentation bin. However, during the stirring process of the flat plates, the materials can only be turned over, and the materials on both sides cannot be fully mixed with the materials in the middle area, resulting in uneven fermentation.

The gap between the outer tank 11 and the inner tank 12 forms a double shell structure. The transmission shaft 5 is rotatably installed inside the inner tank 12. When introducing materials, the worker closes the discharge pipe 15 and opens the feed pipe 14 to allow the materials to be introduced from the feed pipe 14 and introduced into the interior of the inner tank 12. After the introduction of the materials is completed, the feed pipe 14 is closed and hot water is then added. The water inlet pipe and the water outlet pipe are connected to the joint 13, so that hot water is introduced from the joint 13 on one side, and the hot water enters the gap between the outer tank 11 and the inner tank 12, heating the material inside the inner tank 12 so that the material reaches a suitable fermentation temperature.

The spiral plate 17 is evenly provided with notches on one side close to the outer tank 11. There are two perforated discs 18. In the process of introducing hot water, the hot water, under the action of its own gravity, cooperates with the perforated disc 18 and the spiral plate 17. The through holes of the perforated disc 18 and the notches of the spiral plate 17 are used to make the hot water first accumulate at the bottom of the gap under gravity. In the process of gradually increasing the amount of hot water introduced, the hot water is guided by the spiral shape of the spiral plate 17 so that it flows evenly through the surface of the inner tank 12. In combination with the stirring of the material, the heat in the hot water is evenly conducted to the material. The perforated disc 18 is fixedly installed at both ends of the spiral plate 17, and the outer side of the perforated disc 18 is evenly provided with through holes, and the perforated disc 18 is located between the joints 13.

[0020] The third embodiment, based on the first and second embodiments, see Figures 5 to 7 and Figure 9 As shown, the exhaust mechanism 2 includes an exhaust pipe 201, which is fixedly mounted on the top of the outer tank 11, and the bottom end of the exhaust pipe 201 passes through the outer tank 11 and extends to the interior of the inner tank 12. A hole cylinder 202 is fixedly mounted on the top of the exhaust pipe 201, and air holes are evenly opened on the outside of the hole cylinder 202. A grille plate 207 is fixedly mounted on the inner wall of the exhaust pipe 201, and a conical block 211 is fixedly mounted on the bottom of the grille plate 207. The outer diameter of the conical block 211 gradually decreases from top to bottom. By rotating the screw ring 205 and utilizing the threaded connection between the screw ring 205 and the screw rod 204, the position of the screw ring 205 is adjusted to change the spring 206. The degree of compression, when a larger air pressure is needed for exhaust, a larger range is compressed, and when a smaller air pressure is needed for exhaust, a smaller range is compressed. When exhausting, the air pressure inside the inner tank 12 increases, and the gas is guided by the exhaust pipe 201 to pass through the grille plate 207 and contact the bottom of the inner slide 203. The air pressure is transmitted to the spring 206 through the inner slide 203, so that the spring 206 is compressed by the air pressure, causing the inner wall of the inner hole tube 202 of the inner slide 203 to slide upward, opening the air hole of the inner hole tube 202 for exhaust. The inner wall of the exhaust pipe 201 is slidably installed with a counterweight ring 208, and the counterweight ring 208 is located below the grille plate 207.

[0021] The bottom of the counterweight ring 208 is fixedly installed with a conical cover 209, the outer diameter of the conical cover 209 gradually increases from top to bottom, and a through groove is provided at the center of the top of the conical cover 209.

The top of the grid plate 207 is fixedly installed with a screw 204, and the outer side of the screw 204 is slidably installed with an inner slide 203. When the material inside the inner tank 12 surges during the exhaust process, the material The material enters the interior of the conical cover 209 along the exhaust pipe 201, and the conical cover 209 cooperates with the inner retaining ring 210 to make the surging material drive the conical cover 209 to move upward. During the upward movement, the conical block 211 cooperates with the conical cover 209 to close the channel and limit the outflow of material. The outer side of the inner slide 203 fits tightly with the inner wall of the hole tube 202, and the outer side of the screw 204 is threadedly connected with a screw ring 205, and a spring 206 is installed between the screw ring 205 and the inner slide 203.

[0022] A method for using a fermentation device for preparing low-phytic acid wheat bran by fermenting Hericium erinaceus comprises the following steps: S1, material introduction, the materials required for fermentation are placed in the tank body 1 according to the required proportion for fermentation, and the hot water pipe is connected to the tank body 1; S2, stirring and mixing, the motor 3 drives the transmission shaft 5 to rotate inside the tank 1, so that the materials are stirred and mixed by the stirring plate 7 and the guide plate 10, so that the materials are fully contacted and fermented; S3, pressure-controlled exhaust: During the fermentation process, gas will be generated, which will increase the air pressure inside the tank body 1. By adjusting the exhaust mechanism 2, the air pressure inside the tank body 1 is controlled. When the air pressure is high, exhaust is performed to reduce the pressure to ensure a stable fermentation environment. S4, material discharge: after the fermentation is completed, the material that has completed fermentation in the tank body 1 is discharged by opening the discharge position of the tank body 1 for collection.

[0023] During use, the materials required for fermentation are introduced into the interior of the tank body 1 in proportion, and the hot water pipe is connected to the tank body 1. The fermentation material is heated by the introduction of hot water. At the same time, the transmission shaft 5 is driven to rotate by the motor 3 during the heating process to ferment and stir the internal materials so that the materials are fully mixed. During the stirring and heating process, the materials begin to ferment, and gas is generated during the fermentation process, which increases the air pressure inside the tank body 1. During the process of increasing air pressure, the exhaust mechanism 2 is adjusted so that when the air pressure inside the tank body 1 increases to a certain level during the fermentation process, the exhaust mechanism 2 provides power to the exhaust mechanism 2 so that the exhaust mechanism 2 discharges the gas inside the tank body 1 to reduce the air pressure.

[0024] In the tank body 1, when introducing the material, the worker closes the discharge pipe 15 and opens the feed pipe 14, so that the material is introduced from the feed pipe 14 and the material is introduced into the interior of the inner tank 12. After the introduction of the material is completed, the feed pipe 14 is closed, and then the hot water inlet pipe and the outlet pipe are connected to the joint 13, so that the hot water is introduced from the joint 13 on one side, so that the hot water enters the gap between the outer tank 11 and the inner tank 12, and heats the material inside the inner tank 12 so that the material reaches a suitable fermentation temperature. In the process of introducing hot water, the hot water, under the action of its own gravity, cooperates with the perforated plate 18 and the spiral plate 17, and utilizes the through holes of the perforated plate 18 and the notches of the spiral plate 17 to make the hot water first accumulate at the bottom of the gap under gravity, and in the process of gradually increasing the amount of hot water introduced, the hot water is guided by the spiral shape of the spiral plate 17 so that it flows evenly through the surface of the inner tank 12, and cooperates with the stirring of the material to make the heat in the hot water evenly transferred to the material.

[0025] When stirring the material, the transmission shaft 5 driven by the motor 3 drives the support rod 8 and the support ring 6 to rotate inside the inner tank 12 during the rotation process. At the same time, the fixing buckle 9 is driven by the support rod 8, so that the fixing buckle 9 drives the stirring plate 7 to rotate inside the inner tank 12 along the axis of the transmission shaft 5. During the rotation, the stirring plate 7 drives the material to move inside the inner tank 12, so that the materials are fully in contact with each other. At the same time, during the stirring process, the guide plate 10 cooperates with the stirring plate 7 to stir the material. During the forward rotation process, the material is guided to both sides by the twists and turns of the center position of the guide plate 10. During the reverse rotation process, the guide plate 10 concentrates the material to the center position. During the forward and reverse rotation process, the material is turned over, and the materials on both sides are fully contacted and mixed with the material at the center position.

[0026] In the exhaust mechanism 2, by rotating the screw ring 205 and utilizing the threaded connection between the screw ring 205 and the screw rod 204, the position of the screw ring 205 is adjusted to change the compression degree of the spring 206. When a larger air pressure is required for exhaust, a larger range is compressed. When a smaller air pressure is required for exhaust, a smaller range is compressed. When exhausting, the air pressure inside the inner tank 12 increases, and the gas passes through the grille plate 207 and contacts the bottom of the inner slide cylinder 203 through the guidance of the exhaust pipe 201. The air pressure is transmitted through the inner slide cylinder 203 to Feed spring 206, so that spring 206 is compressed by air pressure, so that the inner wall of inner hole cylinder 202 of inner slide cylinder 203 slides upward, opens the air hole of inner hole cylinder 202, and exhausts. When the material inside inner tank 12 surges during the exhaust process, the material enters the interior of conical cover 209 along exhaust pipe 201, and the conical cover 209 cooperates with inner retaining ring 210 to make the surging material drive conical cover 209 to move upward. In the process of upward movement, the conical block 211 cooperates with conical cover 209 to close the channel and limit the outflow of material.
