要望される処であった。Conventional technology and its problems A general circulation type grain dryer has a grain tank placed on top of a ventilation drying section that has a hot air chamber, a grain drying chamber, and a ventilation chamber in parallel, and an elevator installed on one side to dry the grains. A grain discharging valve installed at the bottom of the drying chamber is rotated to allow the grains in the upper grain tank to flow down into the drying chamber and also to be discharged from the hot air chamber. Generally, the grains are dried by hot air flowing in the horizontal direction through the grain removal valve 11, and the grains discharged from the grain removal valve are lifted by an elevator and then supplied to a grain tank for tempering. In the grain dryer,
Regardless of the grain moisture content, the kernels are discharged and circulated by rotating the grain threshing valve at the same speed for a predetermined set time in a unit time, so that the amount of grain discharged from the grain threshing valve ( Compared to low-moisture paddy, high-moisture paddy has a large frictional resistance, and the amount of paddy discharged is lower than that of low-moisture paddy.As a result, the tempering time in the grain tank increases or decreases, which often causes tempering unevenness on dry paddy. However, there are some problems that arise, and there is a constant need for improvements to the device.

The standard grain threshing amount at a < tacking amount) is determined by the rotation time (in seconds) of rotating the grain threshing valve per unit time (1 minute), and the numerical value is determined by experiment. The actual working time of rotating the grain threshing valve just before the 5 stones of paddy reaches the finished moisture value (approximately 15%) is 30.7 seconds per minute). Further, the grain discharging valve 9 has high-moisture grains with high frictional resistance and low-moisture grains with fluidity.
Measure the amount of grain discharged in unit time (1 minute) of A and 9B and the amount of grain discharged for each moisture value to obtain experimental values, and based on the experimental values, calculate the amount of grain discharged according to changes in grain moisture. The coefficient for calculating the actual rotation time (in seconds) of the grain valve in a unit time (1 minute) is calculated as shown in the table below.The rotation time of the grain removal valve in 1 minute according to the grain moisture value S is The above-mentioned data are stored in the ROM 26 so as to be calculated by the reference rotation time (t-30, 7 seconds) While measuring grain moisture, the measurement signal is converted into a digital signal by the A/D converter 24 and input to the CPU 25.

ことになる。Further, since the CPU 25 issues a control signal to intermittently rotate the electric motor 18 via the rotation control unit 21 so that the rotation time flfi (α is seconds) corresponds to each moisture value S stored in the ROM 26, The rotation time of each grain threshing valve 9A, 9B changes depending on the measured moisture value, and the grain threshing amount per unit time (
1 minute), and the grains are fried and supplied to the grain tank 5 to form a grain layer with a constant layer height and then tempered, so the tempering time of each grain is stable. If the grain is stabilized and thoroughly tempered, it will not produce a tempered grain (it will be produced into good quality dry grains and taken out of the machine).
