Abstract
It is an object of the present invention to provide a method which is capable of reducing a crushing rate of grain when the grain such as rice is transported by means of gas through pipes. The temperature of the grain in a grain accommodation tank which is connected to a transportation pipe for grain is measured. A temperature signal indicating this temperature is sent to control means, which determines the temperature of transportation gas so that a difference between this temperature and the temperature of the grain is within a predetermined range. The determined temperature is transmitted to an intercooler so that the temperature of the transportation gas which is sent from a blower and flows through the transportation pipe is controlled to be at the determined specific temperature. Transportation of the grain by means of the transportation gas at this temperature prevents the grain from crushing.
