The calculation of the hulling processing capacity of the hulling machine 3 and the time required for hulling the grains stored in the dryer 1 by the control device 44 is performed as follows. That is, the calculation of the hulling processing capacity of the hulling machine 3 is based on the calculation of the hulling processing capacity of the hulling machine 3.
When hulling is started and the full amount sensor 26 on the upper part of the storage tank 2 no longer detects grains, this no longer being detected is input to the CPU 45 via the timer 45, and the storage tank 2 When the lower grain sensor 27 stops detecting grains, the fact that it has stopped detecting grains is inputted to the CPU 45 via the timer 45, and based on these inputs, the full amount sensor 26 of the storage tank 2 The amount of grain accommodated between the grain sensor 27 position and the grain sensor 27 position is hulled by the hulling machine 3.
45.

The amount of grain stored between the full amount sensor 26 position of the storage tank 2 and the grain sensor 27 position is set and stored in the CPU 45 as, for example, 60 kg. There is. From the above, the rice huller 3

For example, the calculated time required for hulling is 72 seconds,
The amount of grain stored in the storage tank 2 is 60 kg,
The rice hull processing capacity is calculated to be 3000 kg per hour.

[0021] 60 (kg) x 72 (sec) x 3600 (s
ec)=3000 (kg) The time required for hulling the amount of grain stored in the dryer 1 is calculated by operating the loading amount setting knob 37, inputting the content of this operation to the CPU 42, By this input, the amount of grain accommodated in the dryer 1 is detected to be, for example, 2,400 kg, and this accommodation amount of 2,400 kg and the hulling processing capacity of the huller 3 per hour The dryer 1 from 3000kg
The time required for hulling the amount of grain stored in the container is calculated to be 48 minutes, and this 48 minutes is calculated as 48 minutes.

The hot air device 18 is controlled so that the set hot air temperature set by operating the grain type setting knob 36 and the filling amount setting knob 37 becomes the same temperature as the detected hot air temperature in the ventilation chamber. The configuration is such that When performing double drying in which grains are loaded into both the cooling device 12 and the hot air drying device 13 and dried, settings are made by operating the grain type setting knob 36 and the loading amount setting knob 37. When the upper limit of the set temperature is exceeded, the hot air temperature is set using the detected blowing amount detected by the blowing amount sensor 46 provided in the cooling storage chamber of the cooling device 2. Also, when the grains are discharged from the cooling device 12, the data of the hot air drying device 13 is stored.

By being sucked and exhausted, the grains in the drying storage chamber are transferred to the drying storage chamber, the drying chamber, the drying grain collection gutter, the supply gutter 22, the circulation grain hoist 20, the dumping tube 21, and the drying transfer gutter 1.
7, the grains are supplied onto the drying diffusion plate, where they are evenly diffused and reduced into the drying storage chamber, and the grains flowing down the drying chamber are exposed to this hot air and dried, and the grains are dried by the moisture sensor When the grain moisture detected by 23 reaches the finishing target moisture set by operating the moisture setting knob 35, the dryer 1 is automatically stopped and drying of the grains is stopped.

By operating the start switch 32 of the central control device 11 that starts the cooling operation, the dried grains are transferred from the hot air drying device 13 to the cooling device 12 of the dryer 1 and released. By operating the start switch 32 that starts the discharging operation after cooling, the grains are discharged from the dryer 1 through the discharging transfer device 8 and the discharging grain hoist 9 into the grain storage tank 2. When the full amount sensor 26 in the storage tank 2 detects the full amount of grains, the discharge is temporarily stopped.

By operating the start switch 34 of the central control device 11 that starts the hulling operation, the hulling machine 3 and the storage tank 2 are started, and the grains in the storage tank 2 are transferred to the hulling machine.
