PROBLEM TO BE SOLVED: To obtain a grain dryer in which burden on an operator can be lessened by providing a rotation weighing apparatus 104 additionally thereby eliminating the need for estimating management of rotation precisely at the time of receiving grains. SOLUTION: The grain dryer comprises an apparatus for measuring the weight WS of grains at the time of receiving, and means for measuring the moisture level M and a weight W' allowable per stack pin at the time of starting rotation is determined based on the weight WS and the moisture level M. A rotation weighing apparatus is provided in the way of passage of a carrying means from a rotation delivery bin to a rotation receiving bin. When the integrated weight of the weighing apparatus exceeds the allowable weight W', a control means alters the receiving bin. The weight WS and the weighted mean moisture level MS of received grains are determined and then the allowable weight W' is determined at the time of starting rotation and when the allowable weight W' is reached, the receiving bin is altered to next designated one. Since a rotation weighing apparatus 104 is provided additionally, precise estimation of management of rotation is not required at the time of receiving grains and burden on an operator can be lessened.
