A kind of drying machine of what is closed in this creation comprising a conveying mechanism and a drying machine structure. The conveying mechanism includes a feed well, a conveying device and a sensing device, the feed well includes a first outlet and a second outlet, in the conveying device position what feed well and have one can be with respect to the transport unit of the feed well movement, the transport unit alternative carry out a first direction movement or a reversed what first direction second direction movement, the sensing device set the what feed well with sense in the what feed well to the dry material of the universe to the dry inventory of the universe. The drying machine structure includes a drying cylinder, and the inside of the drying cylinder is connected to the first outlet and the air intake vent with a discharge port and one wind regime of connection. Wherein, when in the sensing device senses position what feed well should when the dry material of the universe should be when the dry inventory of the universe be not up to a predetermined amount, the transport unit system carries out the movement of the first direction should convey to the dry material of the universe towards the first outlet direction, when in the sensing device senses position what feed well when the dry material of the universe should be when the dry inventory of the universe reaches the predetermined amount, which carries out the movement of the second direction with should be to the dry material of the universe towards second outlet direction conveying.本創作關於一種乾燥機，其包括一輸送機構及一乾燥機構。該輸送機構包括一進料槽、一輸送裝置及一感測裝置，該進料槽包括一第一出口及一第二出口，該輸送裝置位於該進料槽內且具有一可相對該進料槽運動之傳送部，該傳送部可選擇性進行一第一方向之運動或一反向於該第一方向之第二方向之運動，該感測裝置設於該進料槽以感測位於該進料槽內之待乾燥物料之待乾燥物料量。該乾燥機構包括一乾燥筒，該乾燥筒之內部連通該第一出口、且具有一出料口及一連接一風源之入風口。其中，當該感測裝置感測位於該進料槽內之該待乾燥物料之該待乾燥物料量未達到一預定量時，該傳送部係進行該第一方向之運動以將該待乾燥物料朝該第一出口方向輸送，當該感測裝置感測位於該進料槽內之待乾燥物料之該待乾燥物料量達到該預定量時，該輸送裝置進行該第二方向之運動以將該待乾燥物料朝該第二出口方向輸送。
