Abstract
Description
Technical Field
[0001] This application relates to the field of drying rack technology, and in particular to an adjustable drying rack for drying yellow smoke. Background Technology
[0002] "Sun-dried tobacco" refers to a traditional tobacco-making method, typically used to process certain types of tobacco or spices. This process generally involves exposing tobacco or other plant materials to sunlight, utilizing the sun's heat and ultraviolet rays to promote chemical reactions and achieve specific purposes, such as drying, oxidation, or altering color or flavor. During the sun-drying process, the tobacco needs to be placed on drying racks to dry.
[0003] Traditional drying racks have a relatively fixed structure, and the angle of the drying rack is not easy to adjust according to the direction of sunlight, resulting in low efficiency in utilizing sunlight and requiring a long drying cycle. In addition, the overall number of layers of the drying rack is not easy to adjust according to production needs. When there are fewer layers, drying tobacco requires a lot of space, and when there are more layers, it is difficult to store it. Utility Model Content
