Superheated-steam generator device

Abstract

Provided is a superheated-steam generator device, in which the steam-loop-back structure of a steam-heating pipe is simplified and heaters can be individually attached to or removed from the device. The device includes a first disc, a second disc, a third disc, a fourth disc, and a fifth disc; multiple through-holes respectively are provided to the first disc, the third disc, and the fourth disc; at least one long through-hole (7) and one through-hole (6a) are provided to the second disc; multiple steam-heating pipes are attached to the through-holes of the third disc and to the through-holes of the fourth disc; loop-back grooves and one through-hole (6b) are provided to the fifth disc; heaters that have spiral fins are attached into the through-hole of the first disc so as to cover the through-hole of the first disc; a steam-supply pipe; and a steam-discharge pipe.

Description

technical field [0001] The present invention relates to a superheated steam generating nozzle. More specifically, the present invention relates to a superheated steam generating nozzle having a simple reversing structure of a superheated steam pipe and capable of independently detaching and attaching a heater. Background technique [0002] Superheated steam is steam obtained by further superheating water vapor at 100°C. For example, in a superheated steam oven, foodstuffs are baked or dried by blowing superheated steam over them. In the food conditioning device of Patent Document 1, since a plurality of superheated steam pipes with heaters inside are joined by short pipes, (a) welding of the short pipes can only be carried out in a narrow space, which is relatively difficult; (b) The superheated steam pipe needs to be pierced with holes for connecting short pipes; (c) The overall shape is box-shaped, with a low height, but a large width and depth. Therefore, when the superh...

Problems solved by technology

In the food conditioning device of Patent Document 1, since a plurality of superheated steam pipes with heaters inside are joined by short pipes, (a) welding of the short pipes can only be carried out in a relatively narrow space, which is relatively difficult; (b) The superheated steam pipe needs to be pierced with holes for connecting short pipes; (c) The overall shape is box-shaped, with a low height, but a large width and depth

Therefore, when the superheated steam generator is to be folded into a cylindrical shape like a nozzle, it is extremely difficult to weld the short tube to the superheated steam tube.
