Abstract
Description
Technical Field
[0001] This utility model relates to the field of corn pulp processing technology, specifically a self-rotating corn pulp fermentation tank. Background Technology
[0002] Corn steep liquor is a byproduct of corn starch production. The raw materials are corn grits, water, and corn juice. To make corn starch, corn kernels must first be soaked in sulfurous acid. The soaking solution is then concentrated to produce a yellowish-brown liquid called corn steep liquor. It is rich in soluble protein and growth factors. Due to its relatively high nutrient content, it can be used as an important raw material for the production of culture media such as antibiotics. It provides a natural organic nitrogen source for microbial growth and can also promote the biosynthesis of antibiotics such as penicillin.
[0003] The existing patent announcement number CN 216192227 U discloses a self-rotating corn steep liquor fermenter, comprising a mounting frame, a support pipe fixed to the top of the mounting frame, and a tank body rotatably mounted on the support pipe via a sealing ring. This technical solution, with the tank body rotatably mounted via the sealing ring, keeps the inside of the tank sealed, preventing external dust from entering. Feeding and discharging are done through a feed pipe. When additives are introduced into the tank through the feed pipe, the tank's rotation is controlled, causing the viscous corn steep liquor to slosh around, preventing sedimentation. Simultaneously, the sloshing of the corn steep liquor with the tank's rotation ensures uniform mixing of the corn steep liquor and additives. However, the connection between the output shaft of the stirring motor and one end of the tank via a belt and pulley, with the pulley driving the tank's rotation, fails to achieve multi-layered impact on the flowing material being turned over, potentially causing localized excessively high or low concentrations, thus hindering the uniform distribution of components during fermentation. Summary of the Invention
[0004] To address the above problems, the purpose of this utility model is to provide a self-rotating corn syrup fermentation tank that solves the problem of the inability to achieve multi-layer impact on the tumbled flowing material, which can cause local concentrations to be too high or too low, and ensures the uniform distribution of each component during fermentation. When the material is tumbled and flowing, it touches and impacts the second impact plate. At the same time, some material passes through the second slot, thereby achieving multi-layer impact on the tumbled flowing material through the first and second impact plates. The impact on the material ensures thorough mixing, avoids local concentrations to be too high or too low, and ensures the uniform distribution of each component during fermentation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a self-rotating corn syrup fermentation tank, comprising a support assembly, a tank assembly, and an impact assembly. The support assembly includes a base and a servo motor. The tank assembly includes a fermentation tank. The impact assembly includes a positioning crossbar and a second impact plate. Support side plates are symmetrically welded to the top of the base. The output end of the servo motor is connected to a conveyor belt via a pulley. A feed inlet is connected to the top of the fermentation tank. A discharge outlet is connected to the end of the fermentation tank away from the feed inlet. A cooling layer is provided on the inner side of the fermentation tank. A water inlet pipe is connected to one end of the fermentation tank. A drain pipe is connected to the end of the fermentation tank away from the water inlet pipe. A rotating shaft is connected to one end of the fermentation tank. A first impact plate is connected to the circumferential wall of the outer ring of the positioning crossbar. A first groove is formed on the inner side of the first impact plate.
[0006] The beneficial effects of this invention are as follows: during the rotation of the fermentation tank, the material inside it is tumbled and flows. When the material is tumbled and flows, it touches the second impact plate and impacts it. At the same time, some material will pass through the second slot. Then, through the first impact plate and the second impact plate, the material being tumbled and flows is impacted in multiple layers. The impact on the material makes it fully mixed, avoids local concentrations that are too high or too low, and ensures the uniform distribution of each component during the fermentation process.
[0007] The side support plates are designed for mounting at both ends of the fermenter.
[0008] As a further improvement to the above technical solution: the servo motor is mounted on the top of the base via a bracket, the servo motor is electrically connected to the operation panel, and the servo motor is equipped with a planetary reducer.

[0012] The beneficial effects of this improvement are as follows: after the servo motor is started, the servo motor works and drives the conveyor belt to rotate through the pulley, which in turn drives the rotating shaft to rotate, thereby realizing the rotation of the fermenter.
[0013] To cool the fermenter during this process and prevent the fermentation temperature from becoming too high:
[0014] As a further improvement to the above technical solution: the water inlet pipe is equipped with a sealing plug and is connected to the cooling layer, and the drain pipe is connected to a valve and is connected to the cooling layer.
[0015] The beneficial effects of this improvement are as follows: by setting up a cooling layer, cooling water is added into the cooling layer through the water inlet pipe, and the cooled water is discharged through the drain pipe. In this process, the temperature of the fermentation tank is reduced to prevent the fermentation temperature from becoming too high.
[0016] To allow the fermented products to be discharged through the discharge port:
[0017] As a further improvement to the above technical solution: the feed inlet is equipped with a sealing cover, the discharge port is connected to a valve, and the discharge port and the feed inlet are arranged symmetrically.
[0018] The beneficial effects of this improvement are: the feed inlet is used to add fermentation raw materials such as corn syrup, bacteria, and nutrients, while the discharge outlet is used to discharge the fermented products.

[0021] The beneficial effects of this improvement are as follows: the vent is used to introduce air and oxygen into the fermenter, the filter inside the vent is used to prevent external impurities from entering and maintain a sterile fermentation environment, and the exhaust port is used to discharge carbon dioxide and waste gas generated during the fermentation process.
[0022] To ensure that the material contacts and collides with the first impact plate during the tumbling flow:
[0023] As a further improvement to the above technical solution: both ends of the positioning crossbar are connected to the inner wall of the fermentation tank, and the first impact plate is installed on the outer wall of the positioning crossbar at equal intervals around its circumference.
[0024] The beneficial effects of this improvement are as follows: when the fermenter rotates under the action of the servo motor, the material inside the fermenter will tumble and flow during the rotation process. When the material tumbles and flows, it will touch the first impact plate and collide with it. At the same time, some material will pass through the first impact plate.
[0025] To ensure thorough mixing of the materials through impact and to avoid localized concentrations that are too high or too low:
[0026] As a further improvement to the above technical solution: the second impact plate is installed on the inner wall of the fermenter at equal intervals around its circumference, and a second groove is provided on the inner side of the second impact plate.
[0027] The beneficial effects of this improvement are as follows: during the rotation of the fermenter, the material inside it is tumbled and flows. When the material is tumbled and flows, it touches the second impact plate and collides with it. At the same time, some material will pass through the second slot, and then the first impact plate and the second impact plate will achieve multi-layer impact on the tumbled material. The impact on the material will make it fully mixed, avoid local concentrations that are too high or too low, and ensure the uniform distribution of each component during the fermentation process.
