[0025] Specifically, the hot water tank 3 heats the stored water in it to 90° through steam, and then the hot water is delivered to the hydration tank 2 through the connecting valve, the hydration tank 2 is double-layered and heat-insulated, the heating steam coils 202 continuously heat and insulate the hydration tank 2 during the working process, and the thermometers 203 monitor the temperature of the hot water in the hydration tank 2 in real time, so as to ensure that the water temperature is controlled at 90° at all times during the extraction of neutral oil, and during the extraction, the sesame oil feet in the sediment tank 1 are delivered to the inner cavity of the tank body of the hydration tank 2 through the gear pump 4 to carry out the hydration degumming reaction.

[0026] The hydration tank 2 is provided with a stirrer 5 on the top of the tank cavity, the stirrer 5 comprises a driving motor 501, a stirring rod 502 and stirring blades 503, the driving motor 501 is installed on the top of the tank body of the hydration tank 2, the stirring rod 502 is rotatably installed on the top wall of the inner cavity of the tank body of the hydration tank 2, the output end of the driving motor 501 is connected with the stirring rod 502, and the stirring blades 503 are spirally arranged on the outer periphery of the stirring rod 502.
