In the multi-stage steamer 1, the boiler 3 is mounted on the lower side in the steamer main body 2, and a plurality of steaming basket units 4 are mounted on the upper side in the steamer main body 2 in a multi-stage shape (four stages in the illustrated embodiment). Then, the food placed on each steaming basket unit 4 is heated and cooked by the steam of the boiler 3.
[0006]
The boiler 3 includes a hot water tank 6 that receives water from a water storage tank 5 and heating means such as a gas burner 7 that heats the hot water tank 6 from below. The steam generated from the hot water tank 6 by heating the gas burner 7 is steamed. While being circulated in the main body 2, the combustion gas of the boiler 3 is discharged from the exhaust stack 9.
[0007]
The steaming basket unit 4 is formed of a rectangular box-shaped container having an open top surface, and on the bottom portion, a product to be cooked is mounted using a perforated plate such as a punching metal on the bottom portion in order to flow steam at a constant opening ratio. A basket plate 10 to be placed, a handle 11 for a drawer is provided on the front side, guide rails 12 are provided on both left and right sides, and a rolling roller 13 is attached to the rear end side of each guide rail 12.
