In order to further reduce energy consumption, a roller group can be additionally arranged at the bottom of each steaming channel 3-14, the trays 3-15 slide on the roller group, sliding resistance is obviously reduced, and the energy-saving effect is more obvious.

The tray 3-15 cleaning function of the steaming device 3 is integrated in the steaming box 3-1 with the steam source, and the compact structural design further reduces the space occupied by the steaming device.

As shown in figure 11, a closing plate 3-10 is arranged on the outer side of the lifting device 3-11, the lifting device 3-11 reciprocates up and down between the steaming box 3-1 and the closing plate 3-10, and the push rod 3-13 achieves the pushing effect after penetrating through the closing plate 3-10. The closing plate 3-10 can block the side surface of the lifting device 3-11 to prevent steam from overflowing or flowing into the proving space.

As shown in fig. 11, the thickness of the solid between two adjacent tray chambers 3-12 on the lifting device 3-11 is not less than the height of the steaming channel 3-14, so that when the steaming channel 3-14 is dislocated with the tray chambers 3-12, the two ends of the steaming channel 3-14 can be completely blocked, and an independent space can be formed in each steaming channel 3-14 no matter how the lifting device 3-11 moves, thereby making the steaming environment more stable and being beneficial to improving the product quality.
