Background

It is known in the textile field that during the production of bulk fibers, a dryer is required to dehumidify and dry them. At present, most of dryers for dehumidifying and drying bulk fibers are conventional dryers. Such a conventional dryer includes a cabinet.

Because the air equalizing plate is only arranged on the upper side conveying belt of the belt conveyor, hot air blown out by the air equalizing plate can only blow on the surface layer of the loose fibers and cannot penetrate through the loose fibers.
