The canned tomato sauce sterilization device comprises a conveying belt, a preheating mechanism is arranged on the conveying belt, and the inlet end of the preheating mechanism is communicated with the conveying belt; the outlet end of the preheating mechanism is communicated with a high-temperature sterilization mechanism; the inlet end of the high-temperature sterilization mechanism is communicated with the outlet end of the preheating mechanism; an air injection dewatering mechanism is arranged in the circumferential direction of the conveying belt; the conveying belt sequentially passes through the preheating mechanism, the high-temperature sterilization mechanism and the air injection water removal mechanism. By adopting the preheating mechanism, the retention time of canned tomato sauce in the high-temperature sterilization mechanism can be shortened, the energy consumption of the high-temperature sterilization mechanism is reduced, and the production cost is reduced.
