。Prior Art In conventional dryers, the degree of dryness is adjusted by taking samples of loaded paddy and discharged paddy, measuring their moisture content, and adjusting the hot air temperature, air flow rate, and discharge amount of the dryer. However, since there is usually a 2-3% difference in moisture content between rice paddies, it is difficult to accurately adjust the degree of dryness by measuring the moisture content only at the beginning of rice cultivation. Much depended on the operator's intuition.
