An aerosol delivery device includes an electrical power source, an induction receiver configured to receive a substrate including an aerosol precursor composition such that the induction receiver is in proximity to the substrate, and a wireless power transmitter including an induction transmitter. The induction transmitter is configured to removably receive the induction receiver such that the induction transmitter surrounds the induction receiver. The induction transmitter receive electrical current from the electrical power source that causes the induction transmitter to generate an oscillating magnetic field, and the induction receiver generates heat via eddy currents induced at the induction receiver when exposed to the oscillating magnetic field and thereby heats the aerosol precursor composition to produce an aerosol. Related methods are also provided.

Aerosol delivery device including a wirelessly-heated atomizer and related method

The present disclosure relates to an aerosol delivery device configured to wirelessly heat an atomizer. The aerosol delivery device may include a control body and a cartridge. The control body may include an induction transmitter. The cartridge may include an induction receiver and an aerosol precursor composition. When electrical current is directed to the induction transmitter, the induction receiver may be inductively heated. The heat produced by the induction receiver may form an aerosol from the aerosol precursor composition at the substrate. Related methods are also provided.

A tobacco expansion process and apparatus is provided to form a tobacco batch having a predetermined amount of tobacco, contact the batch with steam, load the batch onto a spool assembly, and impregnate the batch with an expansion agent. A double conduit apparatus is provided to load two simultaneously formed tobacco batches onto opposing sides of the impregnation spool. The tobacco batch is formed within a batch forming chamber comprising a vertically adjustable screen to accommodate different operating parameters and/or different tobacco types and/or forms. The batch is directed through a pneumatically separable zone to a precompaction and heating zone. The separable zone is defined by sequentially operating members, at least two of which form barriers to impede seepage of the expansion agent from the impregnating zone. In the precompaction zone the batch is precompacted against a permeable barrier, steamed, and then loaded onto a spool assembly for impregnation with an expansion agent.
