The invention relates to an
air heating tobacco
flue-cured
machine with improved heating performance. The
air heating tobacco curing
machine comprises a housing and a heating and heat preservation device. The heating and heat preservation device is arranged in the mounting cavity of the housing. The heating and heat preservation device comprises a heat insulating cup, a
smoke containing cup and aheating part. The
smoke-containing cup is provided with a
smoke-containing main cavity and a
contact heat conduction part, and a heating part is arranged below the
contact heat conduction part. Between that out side of the smoke cup and the inner side of the heat insulation cup, an
air convection gap is maintained. A main chamber body side wall is provided with an air flow
radiation heat through hole, that first air inlet of the shell is connected with an
air convection gap, the air enters the main chamber body through the first air inlet, the heat element and the
air convection gap, and the air flow
radiation heating through hole. Therefore, the heat generate by the heating part is transmitted to the smoke body through the combination of the heat contact conduction at the bottom and the
convection radiation of the hot side air. The heating area of the smoke body and the
heating efficiency of the smoke body are improved, the heat is uniformly heated, the tobacco body is omni-directionally heated, the use taste of the user is improved, the tobacco shred is completely baked, and waste of the tobacco shred is avoided.
