Technical field

The invention belongs to the technical fields of tobacco processing, and in particular to a kind of conduction pipe tobacco and its preparation method and application.

Background technique

Electronic cigarette technology at present especially heats cigarette technology of not burning and quickly grows.But due to the cause for heating the cigarette that do not burn Studies of The Aromatic Substances conversion depends on external heat source with transmission, and heat transfer efficiency is low, and shredded tobacco fragrant conversion is not filled with transmission Point, result in waste of resources and heat do not burn cigarette sensory comfort it is poor.

Summary of the invention

In view of the above technical problems, the present invention proposes a kind of conductive pipe tobacco and its preparation method and application.It is of the present invention Conductive pipe tobacco can be realized pipe tobacco spontaneous heating, to improve heat utilization ratio, increase the conversion of pipe tobacco flavor matter and transmission effect Rate, and then promote the sensory comfort for heating the cigarette that do not burn.

A kind of conduction pipe tobacco, comprising: using tobacco leaf or reconstituted tobacoo as substrate, surface is covered with conducting resinl.
