Problems solved by technology

However, this method adopts the combined heat transfer method of the downstream hot air in the cylinder and the heating cylinder wall. For the rebaking process of relatively large flow rate sheet tobacco, it is difficult to ensure that the downstream hot air in the cylinder can fully contact with the tobacco in the cylinder. The processing effect will definitely be affected, and the method of heating the cylinder wall as a whole by the liquid phase heating circulation system consumes a lot of energy

Abstract

The invention provides a convective heat transfer flue-cured tobacco lamina re-curing method and device. The device comprises a rotary cylinder, a feeding device, a discharging device, a bidirectional airlock, a heat exchanger, a moisture discharging fan, a circulating fan and the like. A plurality of longitudinal heating plates are arranged on the inner wall of the rotary cylinder, a hollow shaft-shaped pipeline is arranged at the center of the cylinder and is divided into a front segment and a rear segment, and a plurality of high-temperature jet holes are formed in an outer pipe wall. After threshing and pneumatic separation processes, flue-cured tobacco lamina are fed into the rotary cylinder for processing, the moisture content of the flue-cured tobacco lamina is rapidly reduced, the moisture content of the processed flue-cured tobacco lamina is up to 12-13%, and the tobacco lamina directly undergoes a next packaging process. The raw material processing quality is improved, the device and the process are simplified, and energy consumption can be effectively reduced.

Description

technical field [0001] The invention relates to a tobacco processing method and device, in particular to a closed-type drum-type axial heat transfer sheet tobacco redrying method and device suitable for processing sheet tobacco after leaf stem separation. Background technique [0002] In the process of threshing and re-baking, the tobacco leaves after the initial roasting are sequentially processed by debonding, loosening and moistening, separating leaf stems and re-baking to reach the appropriate moisture and temperature. After packing, they are stored and aged. In each process, the redrying of tobacco leaves has a great influence on the physical quality and sensory quality of the leaves. This process adjusts the moisture content of the tobacco slices after the stem leaves are separated to a certain range through roasting to facilitate storage, and at the same time removes the moisture in the tobacco leaves. Green miscellaneous gas, kills tobacco insects and mold. [0003]...
