And the outer wall of the driving shaft is sleeved with stirring blades. According to the tomato sauce preheater, a servo motor is started, the servo motor drives stirring blades to rotate through an output shaft and a driving shaft, tomato sauce in a storage hopper is guided into a heating cylinder at a constant speed, and then steam is guided into a first groove through a steam pipe; steam exchanges heat with the tomato sauce through the heating cylinder and is condensed into water drops to be discharged through the condensation pipe, meanwhile, the stirring blades drive the tomato sauce in the heating cylinder to be stirred and discharged through the discharging pipe, the situation that the tomato sauce changes taste due to too long heating time is avoided, and the effect of simple and convenient constant-speed preheating is achieved.
