Embodiment 1
[0042] S1. Soak the dry corn in an aqueous surfactant solution for 10 minutes at a room temperature of 25° C., take it out and cool it for 30 minutes until it is semi-dry, and obtain corn that is easy to remove the germ husk;
[0043] S2. At a room temperature of 25°C, use a peeling processing machine to peel the corn in step S1 to remove the inorganic salt contained in the corn to achieve the purpose of deliming;
[0044] S3. At a room temperature of 25° C., use a mill to crush the peeled corn in step S2 to remove the germ, remove the organic matter contained in the corn, and obtain corn pellets to achieve the purpose of degreasing;
[0045] S4. At a temperature of 60° C., dry the corn pellets in step S3 with a drying oven for 2 hours to obtain refined corn pellets;
[0046] S5. Put the corn pellets into the rotary tube furnace, under the protection of 1 atmospheric pressure of nitrogen, increase the temperature by 3 degrees per minute, after rising from room temperature to 1...
