<p><P>PROBLEM TO BE SOLVED: To carry out drying while preventing wrinkling and damage of soybean surfaces by using a grain drier carrying out drying while circulating rice and wheat. <P>SOLUTION: In the grain drier, a storage chamber 2, a drying chamber 3, and a grain collecting chamber 4 are sequentially arranged from top down, a hot air chamber 6 communicated with a combustion device 5 side and an exhaust air chamber 8 communicated with a suction/exhaust fan 7 side are arranged in a grain downflow passage 9 of the drying chamber 3, a feeding means 10 is provided below the grain downflow passage 9, and rice and wheat or beans are selected to carry out drying work. It is composed such that drying work is carried out in a state of driving the feeding means 10 from a combustion start of the combustion device 5 when drying work of rice and wheat is selected, and drying work is carried out in a state of stopping the feeding means 10 for a set time from the combustion start of the combustion device 5 or until it is detected that the beans has reached a set moisture content when drying work of the beans is selected. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
