Technical Field

[0001] This utility model relates to the technical field of cottonseed oil production equipment, specifically to a reaction tank for cottonseed oil production. Background Technology

[0002] The production of cottonseed oil involves multiple reaction processes, including degumming, deacidification, decolorization, and deodorization. As the core equipment, the mixing effect, temperature control accuracy, and ease of slag discharge of the reaction tank directly affect the product quality and production efficiency of cottonseed oil.

[0003] In related technologies, cottonseed oil reaction tanks use a stirring shaft to agitate the oil. A jacket is installed on the outer wall of the tank, and a heat exchange device is installed inside the jacket to heat the tank wall and the oil inside, thereby improving the mixing effect. However, the heat exchange method of this type of reaction tank is relatively simple, the heat exchange area is limited, and the heat exchange speed is slow, which affects the mixing efficiency. To solve the above problems, a reaction tank for cottonseed oil production is proposed. Utility Model Content

The present invention supplies hot water into the heating disc through a heating device, which heats the oil in the reaction vessel by heating the spiral heating tube. The hot water in the heating disc and the return disc in the cylinder also heats the pipe wall of the reaction vessel. The heat lost by the hot water is collected by the recovery device to prevent resource waste, thereby increasing the heat exchange area and the heat exchange rate of the oil in the reaction vessel, thus improving the mixing efficiency of the oil.
