A kind of thermal energy supply control system of more drying machines, comprising controlling mould group in a calculating mould group, a detecting mould group and one. The calculating mould group obtains a preset temperature of each drying machine, a default humidity and one dries the universe time, and the inventory of burning needed for calculating the thermal demand amount of each drying machine, the combustor according to aforementioned condition, and enters the hot blast rate of each drying machine. The detecting mould group detects baking universe temperature, humidity in each drying machine. Mould group is controlled in this and is compared and dries universe temperature and preset temperature, reduces hot blast rate when what increases hot blast rate when drying the low what preset temperature of universe temperature and what dries universe temperature high what preset temperature. Thereby, the thermal energy from same combustor is utilized using aptitude manner, meets the different baking universe condition of each drying machine, and then be able to ascend economic benefit.一種多乾燥機的熱能供應控制系統，包含一計算模組、一偵測模組，及一中控模組。該計算模組獲取每一乾燥機的一預設溫度、一預設溼度，及一烘乾時間，且依據前述條件計算出每一乾燥機的熱能需求量、該燃燒機所需燃燒的物料量，及進入每一乾燥機的熱風量。該偵測模組偵測每一乾燥機內的烘乾溫度、溼度。該中控模組比對烘乾溫度與預設溫度，於烘乾溫度低於預設溫度時增加熱風量，及於烘乾溫度高於預設溫度時減少熱風量。藉此，利用智能方式利用來自同一燃燒機的熱能，滿足每一乾燥機不同的烘乾條件，進而能夠提升經濟效益。
