Embodiment Construction
[0029] The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.
[0030] Such as figure 1 As shown, the stepped redrying system of the present application includes three drying processes, one cooling process and two dampening processes. In other embodiments of the present application, if there are two drying processes, the technical solution of the present application can also be realized.
[0031] The rebaking system of the present application includes the first drying process 2, the second drying process 3, the third drying process 4, the cooling process 5, the first moisture regaining process 6 and the second moisture regaining process 7 from the input port 1 of the tobacco leaves. The procedure ...

The invention relates to a three-dimensional step type re-drying system. By means of the three-dimensional structural design of a drying function area, a cooling function area and a moisture regain function area and through the arrangement of tobacco leaf unloading and loosening devices, the lay-up tobacco leaves are loosened after a first drying process and a first moisture regain process for thetobacco leaves, and the gap is increased, so that transfer of heat or contact with atomized water is facilitated, and not only the uniformity of drying can be improved, but also the moisture contentof the tobacco leaves after moisture regain can be ensured to be uniform. According to the technical scheme, the processes are vertically arranged in a three-dimensional space, so that the occupied area of the re-drying system is reduced, meanwhile, the patrol workload of operators is reduced, and the production cost is effectively reduced.
Description
technical field [0001] The invention belongs to the technical field of equipment for redrying tobacco leaves, in particular to a three-dimensional stepped redrying system. Background technique [0002] The existing tobacco re-baking process is to heat and dry the first-cured tobacco leaves, cool them, and then perform moisture regain treatment to control the moisture content of the tobacco leaves within a certain range, so as to facilitate long-term storage and alcoholization of the tobacco leaves. [0003] At present, most rebaking equipment at home and abroad are tunnel-type mesh belt conveyor rebaking machines, which dry materials by convective heat transfer. The current rebaking method basically passes through the first drying zone, the second drying zone, the third drying zone, It is composed of the cooling zone, the first resurgence zone and the second resurgence zone. In the rebaking equipment of the prior art, the length of each process is tens of meters, and it is ...
