PURPOSE: To elongate the retention time of generated smoke in a main body by forming ventilation openings communicating the inside of a box with the outside thereof at the lower portions of the peripheral side surface of the box, detachably disposing a rack for placing or hanging a raw material thereon and disposing a heat source and a receiver for a smoking material smoked with the heat source above the rack.

CONSTITUTION: Ventilation openings 2 are formed at the lower portions of the peripheral side surface of a box 1 and a receiver 14 is also disposed in the box 1, whereby the generated smoke is retained in the box 1 to package a raw material 10 and subsequently slowly ventilated from the lower ventilating openings 2. The smoking time of the raw material 10 is shortened.
