The cleaning water is introduced into the connecting pipe 62 through the output port and the liquid guide main pipe 63, and then introduced into the multiple liquid guide frames 61, and is evenly sprayed on the lower surface of the conveyor belt 23 through the multiple spray holes 601. With the automatic transmission of the conveyor belt 23 and the contact between the cleaning brush 64 and the lower surface of the conveyor belt 23, the cleaning brush 64 automatically cleans the lower surface of the conveyor belt 23 with the cleaning water, and the waste water generated by the cleaning falls into the auxiliary bottom frame 41 and is collected.

[0057] By controlling the driving block 44 to move back and forth in the auxiliary bottom frame 41, the scraper 43 is driven to move back and forth in the auxiliary bottom frame 41. Since the bottom end of the scraper 43 contacts the inner lower wall of the auxiliary bottom frame 41, and the side wall of the scraper 43 contacts the inner side wall of the auxiliary bottom frame 41, the scraper 43 cleans the impurities attached to the inner wall of the auxiliary bottom frame 41. At the same time, the cleaned impurities, condensed water and waste water are pushed to be automatically discharged into the collecting bucket frame 5 through the waste discharge groove 401, and discharged through the waste discharge pipe 51, thereby automatically cleaning the collected condensed water, waste water and impurities.

8. The track-type preheating device for continuous steaming of rice and flour products according to claim 1, characterized in that: An observation groove is provided at the top of one side of the cooking outer frame (3), and an observation window (33) is fixedly provided in the observation groove.

9. The track-type preheating device for continuous steaming of rice and flour products according to claim 2, characterized in that: A first motor (24) is fixedly mounted on one side of one of the transmission side frames (21), and a driving end of the first motor (24) and one end of a corresponding transmission roller (22) are fixedly mounted.

10. A process using the track-type preheating equipment for continuous steaming of rice and flour products according to any one of claims 1 to 9, characterized in that: The steps include: Step 1, connecting the end of the liquid guide pipe (63) to the output port of the cleaning water output system, controlling the first motor (24) to start and drive the corresponding transmission roller (22) to rotate, thereby driving the transmission belt (23) to transmit, while the transmission roller (22) rotates, cooperate with the transmission of the second sprocket (46), the third sprocket (461) and the second chain (462), control one of the auxiliary shafts (45) to rotate, drive the first sprocket (451) to rotate and drive the first chain (452) to transmit, thereby driving the drive shaft (453) to transmit, because the drive shaft (453) is movably engaged in the corresponding drive longitudinal groove (441), the drive shaft (453) transmits and controls the drive block (44) to reciprocate in the auxiliary bottom frame (41); Step 2: placing the rice and flour products to be cooked on the conveyor belt (23); the rice and flour products are transported in a track-like manner as the conveyor belt (23) is transported; a plurality of partitions (34) separate the cooking outer frame (3) into a plurality of cooking bins; each cooking bin is provided with a steam spray frame (35); an external steam generator is controlled to input steam into the steam spray frame (35); thus, steam of different temperatures is transported to each cooking bin through the plurality of steam spray frames (35); and the rice and flour products transported on the conveyor belt (23) are continuously preheated and cooked at different temperatures, so that the plurality of rice and flour products are heated evenly; and a staff member observes the cooking processing effect of the rice and flour products in the cooking outer frame (3) through the observation window (33); The first heat-insulating plate (32) is made of a high-density foam plate to insulate the temperature in the cooking outer frame (3); the second heat-insulating plate (42) is made of a high-density foam plate to insulate the temperature in the auxiliary bottom frame (41), thereby improving the cooking effect of the rice and flour products; Condensed water generated during cooking falls into the auxiliary bottom frame (41) and is collected. The cleaning water output system is controlled to be turned on. The cleaning water is introduced into the connecting pipe (62) through the output port and the liquid guide main pipe (63), and then introduced into the multiple liquid guide frames (61). It is evenly sprayed on the lower surface of the conveyor belt (23) through the multiple spray holes (601). With the automatic transmission of the conveyor belt (23) and the contact between the cleaning brush (64) and the lower surface of the conveyor belt (23), the cleaning brush (64) automatically cleans the lower surface of the conveyor belt (23) with the cleaning water, and the waste water generated by the cleaning falls into the auxiliary bottom frame (41) and is collected. By controlling the driving block (44) to move back and forth in the auxiliary bottom frame (41), the scraper (43) is driven to move back and forth in the auxiliary bottom frame (41). Since the bottom end of the scraper (43) contacts the inner lower wall of the auxiliary bottom frame (41), and the side wall of the scraper (43) contacts the inner side wall of the auxiliary bottom frame (41), the scraper (43) cleans the impurities attached to the inner wall of the auxiliary bottom frame (41). At the same time, the cleaned impurities, condensed water and waste water are pushed to be automatically discharged into the collection bucket frame (5) through the waste discharge groove (401) and discharged through the waste discharge pipe (51), thereby automatically cleaning the collected condensed water, waste water and impurities.
