The invention relates to an agricultural and sideline product drying baking room which comprises a drying room, a hot source room and a sealing door. An agricultural and sideline product carrying frame is arranged in the drying room, a partition wall is arranged between the drying room and the hot source room, and an interval window is formed between the partition wall and the top of the drying room. A multilayer top space and a clearance notch are arranged above the drying room, and four ventilation holes are formed in the partition wall. A flow guide device, a hot source generator and an airblower are arranged in each ventilation hole. The agricultural and sideline product drying baking room can be used for conducting drying processing on agricultural and side products, and the energy efficiency ratio is high. The drying time can be greatly shortened, and the baking quality and the yield of agricultural and sideline products are improved.
