▎ 摘　　要

NOVELTY - Grain drying system comprises a drying module (10) provided with a tempering section (4), an air outlet section (1), a far infrared graphene section (2) and an air inlet section (3). The upper and lower ends of the air-inlet section are provided with the far-infrared graphene section and the air outlet segment. The temperature-temperature section is a hollow cavity (41) with the upper and the lower openings. The side wall of one side of the side is provided with an air intake cavity. The air outlet at the end of the end is located on the side wall opposite to the outlet cavity. The hole diameter of the porous structure is less than the outer diameter of a grain. The air intake channel and the top portion of the top of the outlet section are cone-shaped. The direction of the cone top portion to rise and fall is opposite to that of the grain flow direction. USE - Grain drying system based on graphene infrared and air convection coupling. ADVANTAGE - The system provides a grain far infrared heating drying and ventilating and humidity discharging drying system at the same time, so as to improve the graphene and speed of the far infrared drying grain, thus avoiding the grain surface moisture discharging caused by the problem of drying efficiency is reduced. The grain cracking phenomenon is effectively prevented when heating and drying, when the water gradient in the grain is effectively eliminated, and the heating temperature of the grain (60 degrees centigrade will not happen cracking phenomenon) is improved to shorten the drying time, improve the drying efficiency. The water migration from the grain inside is quickly taken away by the air flow, furthest improves the efficiency and graphene of the system.
