The utility model discloses a double-cavity sectional type heating non-combustion device which comprises an equipment body, a first heating cavity, a second heating cavity and an electromagnetic induction coil, the electromagnetic induction coil is used for receiving a cigarette inserted with a magnetic conductive element, and the magnetic conductive element is detachably arranged in a tobacco section of the cigarette; a resistance-type heating device is arranged in the second heating cavity, and the heating surface of the resistance-type heating device and the outer surface of the cigarette form a non-contact heating space; the cigarette inserted with the magnetic conductive element is placed in the first heating cavity, and the magnetic conductive element generates eddy current through electromagnetic induction heating so as to heat the interior of the cigarette; and after the cigarette with the heated interior is taken out and the magnetic conductive element is removed, the cigarette is transferred to the second heating cavity, and the exterior of the cigarette is secondarily heated through hot airflow generated by the resistance-type heating device. According to the double-cavity sectional type heating non-combustion device, the electromagnetic induction coil is firstly used for heating the interior of the cigarette inserted with the magnetic conductive element, then the resistance type heating device is used for generating hot air flow to conduct secondary heating on the exterior of the cigarette, and uniform heating of the cigarette from inside to outside is achieved.

The utility model discloses a hot -blast circulation vacuum drying equipment, including drying box, heating assembly, sealing door, flat car, drying box is located in factory building and is equipped with hot -blast drying assembly in drying box top, heating assembly is located in drying box, and heating assembly includes circulating row pipe, first heating box, circulating row pipe is equipped with several groups and is equipped with in drying box respectively in several groups circulating row pipe, and sealing door is located in one end of drying box, and flat car is located in one side of drying box, is used for sending the material of waiting dry to in drying box, improves the convenience and continuity of material loading and unloading, adopts the mode of circulating row pipe and high temperature medium heat exchange, compares traditional electric heating pipe or single hot -blast heating, and the heat source evenly releases from the all around of drying box, solves the problem of local overheating and uneven temperature distribution, makes material drying quality more stable, simultaneously, medium circulation heat exchange reduces heat loss, and cooperates hot -blast secondary heating, and the temperature rising speed is greatly improved, and drying period is shortened.
