PROBLEM TO BE SOLVED: To provide a method and apparatus for aeration drying of root crops, which eliminates the need of manually covering with a sheet or visually making sure of aeration from the sheet, and which makes efficient drying possible in the occurrence of odd quantity.SOLUTION: Root crops are housed in a plurality of storage containers 10, with the plurality of storage containers 10 piled up in multiple steps and multiple rows in a storage chamber 4 to form an accumulation of the storage containers 10. The side wall surfaces of the accumulation of the storage containers 10 are covered with non-air-permeable walls 11, 17, 17, 25, with the inward space made a drying wind-tunnel K capable of vertical aeration to perform aeration drying, in the method of aeration drying of root crops. In the drying wind-tunnel K, for the purpose of making the size of the cross section variable in accordance with the number of storage containers 10, at least one side wall surface of the accumulation of the storage containers 10 is covered with the non-air-permeable wall 25 that is movably installed inside the storage chamber 4.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】人手によって手作業でシートを覆ったり、目視によってシートからの通気抜けを確認するなどの必要がなく、また、端量が生じた場合でも効率的な乾燥を行うことが可能な根菜類の通風乾燥方法及びその装置を提供する。【解決手段】複数の収容容器10に根菜類を収納し、複数の収容容器10を貯留室4内に多段多列状に積み重ねて収容容器10の集積物を形成し、収容容器10の集積物の側壁面を非通気性の壁11,17,17,25で覆って、その内方の空間を上下方向に通風可能な乾燥風洞Kとして通風乾燥を行う根菜類の通風乾燥方法であって、乾燥風洞Kは、記収容容器10の多寡に応じて横断面の大きさが可変となるよう、収容容器10の集積物の少なくとも一側壁面を、貯留室4内に設けられた移動可能な非通気性壁25によって被覆した。【選択図】図1
