Description

Technical Field

[0001] This utility model relates to the field of corn soaking water treatment technology, and in particular to a treatment system for reducing the toxin content in corn soaking water. Background Technology

[0002] Corn soaking water is a byproduct of wet starch production. It contains dry matter, phytic acid, protein, lactic acid, calcium, magnesium, and other beneficial components. However, due to environmental factors, corn is prone to mold growth and toxin production during storage, resulting in high levels of vomitoxin and fumonisin in the soaking water. Current research focuses on recovering phytic acid, lactic acid, and calcium and magnesium ions from the soaking water. While protein recovery is also possible, the high levels of vomitoxin and fumonisin in the soaking water mean that the recovered protein contains significant amounts of toxins, posing a safety hazard if used directly as animal feed. Therefore, it is necessary to develop a treatment system to reduce the toxin content in corn soaking water. Utility Model Content

[0012] After adopting the above technical solution, the beneficial effects of this utility model are:

[0013] The treatment system for reducing the toxin content in corn soaking water includes a first filtration device connected to a corn soaking water delivery pipeline. The filtrate outlet of the first filtration device is connected to a pH adjustment vessel. The outlet of the pH adjustment vessel is connected to a resin column. The outlet of the resin column is connected to a first concentration device. The concentrate outlet of the first concentration device is connected to an enzymatic hydrolysis vessel. The inlet of the enzymatic hydrolysis vessel is connected to a surfactant storage tank. The outlet of the enzymatic hydrolysis vessel is connected to an adsorption device.

The concentrate outlet of the second concentration device is connected to a drying device. The outlet of the drying device is connected to a product storage tank. In actual production, the corn soaking water after phytic acid adsorption is pumped into the first filtration unit via a pipeline. The collected filtrate then flows through a pipeline into a pH adjustment vessel, where it is adjusted to a suitable temperature and pH before entering a resin column. Some toxins are adsorbed by the resin in the column. The effluent then flows through a pipeline into the first concentration unit for concentration. The resulting concentrate and surfactant flow through pipelines into an enzymatic hydrolysis vessel, where a complex enzyme effectively degrades a large amount of toxins. The degraded solution then flows through a pipeline into an adsorption unit, where the adsorbent further removes toxins. The solution from the adsorption unit then flows through a pipeline into the second filtration unit. The filtered filtrate then enters the second concentration unit, and the concentrated solution flows into a drying unit. The dried protein is stored in a product storage tank. This processing system is rationally designed and can operate continuously. By employing resin adsorption, complex enzyme degradation, and adsorbent adsorption, it effectively reduces toxin content and ensures protein safety.

The vessel body is externally jacketed and internally equipped with a stirring shaft. One end of the stirring shaft is connected to a motor, and multiple stirring rods are mounted on the shaft. The filtrate enters the vessel body through a pipe, and the pH adjusting agent is added. A suitable temperature is provided by the heat transfer medium in the jacket. Once the motor starts, it drives the stirring shaft and multiple stirring rods to mix the filtrate and pH adjusting agent, improving stirring efficiency and ensuring the filtrate reaches a suitable temperature and pH for subsequent processing.

[0016] Both the first and second concentration devices include a vessel body, with an inlet at the top and a outlet at the bottom. The vessel body has an external jacket and an internal rotating shaft. One end of the shaft is connected to a motor, and a stirring frame is mounted on the shaft. Multiple stirring rods are mounted on the stirring frame, each with multiple stirring teeth, and a stirring plate is attached to the end of each stirring rod. The feed liquid enters the vessel body and is heated by a heat transfer medium in the jacket. After the motor starts, it drives the rotating shaft, stirring frame, multiple stirring rods, stirring teeth, and stirring plate to work together to stir the feed liquid, ensuring uniform heating and significantly improving concentration efficiency.

[0017] The enzymatic hydrolysis vessel consists of a vessel body with a liquid inlet, an enzyme inlet, and a surfactant inlet at the top, and a discharge outlet at the bottom. The vessel body is externally jacketed, and internally houses a stirring shaft, a temperature sensor, and a pH sensor. The temperature and pH sensors are electrically connected to a controller. One end of the stirring shaft is connected to a motor, and multiple stirring plates are mounted on the shaft. The feed solution, compound enzyme, and surfactant enter the vessel body, where a suitable temperature is provided by a heat transfer medium in the jacket. The temperature and pH sensors detect the temperature and pH of the feed solution. Once the motor starts, it drives the stirring shaft and multiple stirring plates to rotate, improving mixing efficiency and ensuring thorough contact between the feed solution, compound enzyme, and surfactant, thus achieving effective degradation of toxins.

When the liquid enters the tank and the adsorbent is added, the microwave treatment activates the motor, driving the stirring shaft and multiple stirring blades to rotate. This ensures thorough contact and mixing between the adsorbent and the liquid, further achieving the adsorption of toxins.

[0024] In actual production, the corn soaking water after phytic acid adsorption is pumped into the first filtration device (effectively removing small amounts of macromolecules and suspended solids) via a pipeline. The collected filtrate then enters a pH adjustment vessel, where it is adjusted to a suitable temperature and pH before flowing into a resin column. Some toxins are adsorbed by the resin in the column. The effluent then enters a first concentration device for concentration. The resulting concentrate and surfactant enter an enzymatic hydrolysis vessel, where a complex enzyme effectively degrades a large amount of toxins.
