Abstract
It is an object of the present invention to provide a method for reducing crushing of grain when the grain having Vickers hardness Hv in a range of 11.ltoreq.Hv.ltoreq.14 is transported by means of gas. The present invention is a gas transportation method for grain having Vickers hardness Hv in a range of 11.ltoreq.Hv.ltoreq.14, and gas transportation is performed under the condition that a velocity V of transportation gas is set at a value in a range of 10 m/s.ltoreq.V.ltoreq.20 m/s. Alternatively or additionally, a blending ratio .mu. expressed as a ratio of a flow amount of the grain (kg/H) to a flow amount of the transportation gas (kg/H) is set at a value in a range of (3 V-30).ltoreq..mu..ltoreq.(3 V-20).
