To provide a drying facility and a heating amount control method capable of appropriately controlling a water content of an object to be dried with a simple configuration.SOLUTION: A drying facility 10 has a dryer 14 that heats and dries sludge, and a transport device 16 that transports the sludge discharged from the dryer 14. In the transport device 16, a water content sensor 50 is installed in a retention area where sludge is retained to a predetermined thickness or more, and the water content sensor 50 measures a water content of dry sludge. A heating amount control unit 66 controls a heating amount for the sludge in the dryer 14 based on the water content of the dry sludge measured by the water content sensor 50.SELECTED DRAWING: Figure 1 【課題】 簡易な構成で被乾燥物の含水率を適切に制御できる乾燥設備及び加熱量制御方法を提供する。【解決手段】 乾燥設備１０は、汚泥を加熱して乾燥させる乾燥機１４と、乾燥機１４から排出された汚泥を搬送する搬送装置１６と、を有する。搬送装置１６において汚泥を所定の厚さ以上に滞留させる滞留領域に含水率センサ５０が設置され、含水率センサ５０は乾燥汚泥含水率を測定する。加熱量制御部６６は、含水率センサ５０で測定した乾燥汚泥含水率に基づいて乾燥機１４における汚泥に対する加熱量を制御する。【選択図】 図１
