3) Starting the drying roller, driving the grains to roll in the drying roller by the rotation of the drying roller, opening regulating valves on the hot air pipe and the cold air pipe to simultaneously introduce hot air and cold air into the drying roller, controlling the air blowing temperature to be constant, and drying the grains;
4) In the process of drying grains, the grain water data collector rolls along with the rotation of the drying roller, and the collecting ball of the grain water data collector can also relatively rotate on the sensor protective shell, so that the grain water data collector can roll to any corner in the drying roller;
5) In the process that the grain moisture data collector rolls in the drying drum, wet air in the grain stack can enter the acquisition cavity through the acquisition holes in the acquisition balls, and then air humidity data in a specified time interval are acquired through the two sensor probes in the acquisition cavity, and the two acquired air humidity data are sent to the control system;
6) A signal conversion module in the control system converts the received air humidity data into a grain moisture numerical value and sends the grain moisture numerical value to a data processing module;
7) After the data processing module in the control system averages the two received grain moisture values, the two received grain moisture values are compared with a preset threshold value for analysis, and whether the grain is dry is judged;
8) When the moisture value of the grain exceeds a preset threshold value, the grain is unqualified in drying within a specified time, and the control system generates a wind temperature adjusting instruction and sends the wind temperature adjusting instruction to a controller in the cold air pipe adjusting valve;
9) After the controller in the cold air pipe governing valve received wind temperature regulation instruction, the degree of opening and shutting was adjusted to the control governing valve, and then reduced the cold wind volume of blowing into in the drying drum, adjusted the wind temperature, increased the temperature of blowing for the stoving to grain.
