Claims26
A fragrance dispenser comprising:
- a receptacle for receiving an aromatic substance to be heated;
- a heat exchanger being connectable to the receptacle for heating air to go through the receptacle, the heat exchanger having a housing having a chamber containing at least one plate forming a means for agitating the air, the plate sealing most of the heat exchanger housing from the receptacle, the plate defining an open space which causes agitation and mixing of the air by subjecting the air flow to a turn of direction.
A method for producing an aroma from an aromatic substance, comprising:
- placing the aromatic substance in a receptacle to be heated;
- and
- attaching a heat exchanger to the receptacle for heating air upstream of the receptacle, and agitating the air as it is heated by conveying the air over a plurality of approximately parallel plates which are staggered with respect to each other to define a flow path which subjects the heated air to shear forces;
- and
- passing the heated air over the aromatic substance.
