[Liquid tank 49 for storing oil]
As shown in FIG. 9, the liquid tank 49 for storing oil basically has the same structure as the liquid tank 42 for storing detergent-added water, and therefore, the same reference numerals as those for the liquid tank 42 will be added to the description. Replace.
The oil is for adhering new oil to the endless loop body 2. Spices, seasonings and the like may be added to the oil.

The action and effect of the cooker configured as described above will be described.
(1) When the product to be cooked is thrown onto the endless loop body 2 from the product input portion 8 to be cooked, it is conveyed to the auxiliary material spraying portion 11 by the endless loop body 2 and from the auxiliary material spraying pipe 13 as needed. Secondary material is sprayed.

(2) Subsequently, the product to be cooked is conveyed to the three superheated steam cooking units 16 one after another by the endless loop body 2, and the superheated steam is sprayed from the superheated steam spray pipe 18 to cook. The superheated steam is generated by heating the steam generated by the steam generator 21 while flowing through the flow path of the superheated steam generator 22. Since the steam flows in the flow path while being in contact with the surfaces of the box body 24, the partition plates 27, 29, and the cylinder body 31 heated by the burner 34, it is efficiently heated to become superheated steam. In particular, since the lower end of the cylinder 31 is open from the box 24, the cylinder 31 is easily heated by the burner 34. Further, since the upper end of the cylinder body is partially opened from the box body 24, the heat of the burner 34 is appropriately released upward after being distributed throughout the cylinder body. The heat of the box body 24 is radiated or conducted to the superheated steam cooking unit 16 and is also used for heating the superheated steam cooking unit 16. As described above, the superheated steam generator 22 has a simple structure, is not bulky, and can be provided at low cost.

(3) Subsequently, the product to be cooked is conveyed to the water spraying portion 35 by the endless loop body 2, and water is sprayed from the water spraying pipe 35 as needed to blow oil from the surface.
(4) Subsequently, the food to be cooked is conveyed to the food product taking-out portion 39 by the endless loop body 2 and taken out from the endless loop body 2.

(5) Subsequently, the portion of the endless loop body 2 from which the product to be cooked is taken out is introduced into the liquid tank 42 for storing the detergent-added water. Dirt such as oil and debris after cooking adhering to the endless loop body 2 is floated by detergent-added water and removed by a rotating roll brush 43.
(6) Subsequently, the same portion of the endless loop body 2 is introduced into a liquid tank 47 for storing water having a temperature of less than 50 ° C., and the dirt remaining on the endless loop body 2 is removed by a rotating roll brush 43 together with detergent-added water. Will be removed.
(7) Subsequently, the same portion of the endless loop body 2 is introduced into a liquid tank 48 that stores water at 50 ° C. or higher, and the endless loop body 2 is warmed and further rinsed with a rotating roll brush 43. ..
In this way, the endless loop body 2 can be continuously and sufficiently washed.

(8) Subsequently, the same portion of the endless loop body 2 is introduced into the liquid tank 49 for storing oil, new oil adheres to the endless loop body 2, and is reliably rubbed with a rotating roll brush 43. .. This oil prevents the product to be cooked from sticking to the endless loop body 2 in the next cooking of the product to be cooked.
(9) Subsequently, the same portion of the endless loop body 2 returns to the cooked product charging unit 8, and the next cooked product is charged.

The present invention is not limited to the above-described embodiment, and can be appropriately modified and embodied without departing from the spirit of the invention.
