An extracting device includes a housing for receiving a material to be extracted and to be heated into steam. An upper casing is disposed in the upper portion of the housing and has one or more steam flowing orifices. A box is disposed in the lower portion of the housing and coupled to the casing. A container is disposed above the casing, and a lower casing is attached to the bottom of the upper casing and coupled to the container. The steam may flow through the casings and the container and the box without heat loss.
