Description

Technical Field

[0001] The present invention relates to the technical field related to the drying of cigar tobacco leaves, and particularly to a ventilation and oxygen supply system for drying cigar tobacco leaves and a usage method thereof. Background Art

[0002] The drying of cigar tobacco leaves is one of the most important processes in the production of cigar tobacco leaves. After the fresh cigar tobacco leaves are picked, they enter the process of stringing and drying, which is also called the drying process.

[0003] For the drying method of cigar tobacco, most of them adopt manual stringing of tobacco leaves and then lift them onto the tobacco drying rack for fixed drying. The drying of tobacco leaves requires blowing air to increase oxygen to prevent tobacco leaves from mildewing and improve the drying quality of tobacco leaves. However, the current manual blowing method has uneven effects, high labor intensity and low efficiency.

[0004] Therefore, how to provide a system that can evenly blow air and increase oxygen to the dried tobacco leaves to prevent tobacco leaves from mildewing, and then improve the drying quality of tobacco leaves has become a technical problem that needs to be solved urgently by those skilled in the art.
