Air heating tobacco curing machine with improved heating performance

Abstract

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.

Description

technical field [0001] The invention relates to the field of flue-curing machines, in particular to an air-heating flue-curing machine with improved heating performance. Background technique [0002] Existing tobacco flue-curing machines are implemented in a relatively simple way, either by heating from the outside to the inside, and the heat energy generated by the heating components is directly transferred to the heat-conducting cup, and then transferred to the solid smoking material to heat it; Towards the outside, the heating element is directly inserted into the inside of the smoking material, and the generated heat energy is directly transferred to the solid smoking material to be heated by roasting. The above two methods have common defects: the temperature of the inner and outer parts of the baked and heated material is uneven, the heating area is small, and the heating efficiency is low, which affects the user's experience. Among them, in the internal heating metho...

Problems solved by technology

[0002] Existing tobacco flue-curing equipment is implemented in a relatively single way, either by heating from the outside to the inside, and the heat energy generated by the heating element is directly transferred to the heat conduction cup, and then transferred to the solid smoking material for roasting and heating; or it is heated by the inside Outwardly, the heating element is directly inserted into the smoking material, and the heat energy generated is directly transferred to the solid smoking material for heating.

The above two methods have common defects: the temperature of the inner and outer parts of the heated material is uneven, the heating area is small, and the heating efficiency is low, which affects the user's experience.

Among them, with the internal heating method, it is difficult to roast all the shredded tobacco, which will easily lead to waste of shredded tobacco

[0003] In addition, existing flue-cured tobacco machines generally have the problem of heat loss, resulting in more energy consumption

In addition, the existing heat conduction cup is fixedly connected with the smoking set, which is inconvenient to disassemble and is not conducive to cleaning the smoke residue after baking
