Tobacco curing barn with diversion structure

Abstract

The invention discloses a tobacco curing barn with a diversion structure. The tobacco curing barn comprises a tobacco loading chamber (1) and a heating chamber (2), wherein a heating device (5) is arranged in an upper cavity (3) of the heating chamber (2); the tobacco loading chamber (1) and the heating chamber (2) are separated by a heat insulating wall (6); an air return opening (7) is formed in the upper part of the heat insulating wall (6), and is used for communicating the tobacco loading chamber (1) and the upper cavity (3); an air supply outlet (8) is formed in the lower part of the heat insulating wall (6), and is used for communicating the tobacco loading chamber (1) and the lower cavity (4); a axial flow fan (9) is arranged between the upper cavity (3) and the lower cavity (4); and a diversion plate (10) is arranged in the lower cavity (4), and is inclined toward the bottom of the air supply outlet (8). According to the tobacco curing barn, hot wind blasted from the axial flow fan is buffered and enters the tobacco loading chamber from the air supply outlet due to the arrangement of the diversion plate, so that air in the tobacco loading chamber is uniform and the tobacco curing quality is guaranteed.

Description

technical field [0001] The invention relates to a tobacco curing room, in particular to a tobacco curing room with a diversion structure, and belongs to the technical field of tobacco leaf drying devices. Background technique [0002] Tobacco curing is a process that consumes a lot of heat. During the curing process, the air in the tobacco chamber is heated by the heating device in the heating chamber, and then, under the action of the axial flow fan in the heating chamber, enters the tobacco chamber from the air supply port. After heat exchange, the suspended tobacco leaves flow back to the heating device in the heating chamber through the air return port to realize heat circulation. [0003] However, in the existing structure of the flue-cured room, the hot air is directly blown into the tobacco-loading room from the air supply port through the axial fan, which is easy to cause uneven airflow in the tobacco-filling room, resulting in uneven color quality of the tobacco lea...
