The invention discloses a gas jet flow impact type tumbler heating and baking integrative machine, combines the gas jet flow impact heating and baking technology with the tumbler drying technology. The invention comprises a cylinder cover (1), a cylinder body (2), an airflow distribution room (3), an air access central pipe (5), a bearing and bearing sleeve mechanism (7), a ventilation device (8), a temperature and humidity sensor (9), air access elbow pipe sections (10, 11), air access straight pipe sections (12, 14), a heating device (13), a machine frame (15), air access spiral cases (16, 17), a fan mechanism (18), a speed reducer (19), a chain drive mechanism and a supporting roller mechanism (25). The integrative machine is characterized in that the material is heated evenly, and the heat utilization rate is high. The integrative machine takes the air as heating medium, adopts the pipeline design which can recycle the hot air, is clean, can protect environment and save energy, can flexibly adjust the diameter, inclination angle and height of the orifice according to the size of the material, has strong adaptability to the material, and has bi-service obvious economic benefit of drying and baking.
