An apparatus for concentrating the oxygen content of and injecting aroma into a stream of air and delivering the stream of air to the nostrils of a person includes an air intake filter in fluid communication with the air compressor for drawing a stream of air out of the surrounding atmosphere; a sieve bed in fluid communication with the air intake means, each sieve bed containing a quantity of nitrogen absorption material and having sieve bed input and output valve mechanism; so that the sieve bed extracts nitrogen from the air stream so that the proportion of oxygen exiting the sieve bed is elevated, and as the input valve mechanism closes, the sieve bed output valve mechanism opens and vents absorbed nitrogen from the sieve bed to the atmosphere; an aroma chamber containing aroma releasing material in fluid communication with the output valve mechanism.

The present invention is a vaporizer apparatus (1) and method for uniformly extracting active ingredients of specimen of crude natural product, or inert particulate matrix impregnated with volatile substances without pyrolysis which uses hot air (2), or a heated inert gas stream to volatilize the specimen. The heated air or gas in introduced from below (from either a hot air gun or a high-pressure tank connected to a heat exchanger), and ascends through in most embodiments through a permeable support structure (4) (e.g., fritted glass disk, etc.) subsequently causing specimen particules disposed on the permeable support structure to be suspended within the confines of an isolation chamber (5).

A vaporizer apparatus and method for uniformly extracting active ingredients of a specimen of crude natural product or inert particulate matrix impregnated with volatile substances, without pyrolysis, which uses hot air or a heated inert gas stream to volatilize the specimen. The heated air or gas is introduced from below (from either a hot air gun or a high pressure tank connected to a heat exchanger) and ascends through a permeable support structure (e.g., fritted glass disk, etc.), subsequently causing specimen particles disposed on the permeable support structure to be suspended within the confines of an isolation chamber. This allows a maximized gas extraction exposure for each suspended particle, and promotes a uniform extraction of the aggregate charge through its periodic mixing. A filter prevents the particles from being inhaled by the user. During device disuse, the heated airstream flows through an optional side-arm of the vaporizer apparatus, preventing wasteful loss of active ingredients. In another embodiment, the side-arm can also be used to divert mixed purge gases from the specimen required to be under inert gas during its extraction.
