With conveyor dryers, each zone acts in a similar fashion to a cabinet dryer. The carrier (typically air) is drawn in through an inlet duct or recycle channel into the heating compartment. The air is heated to the required temperature in this region and then distributed into the drying zone.
The conveyor belt speed is calculated as the circumference of the drive roller times the rotations per minute (RPM) of the motor. If there is any gear reduction, don't forget to apply the ratio to the RPM before multiplying the circumference. Conveyor belt speed = Drive roller circumference Motor RPM

Belt feeder calculations require knowledge of the consolidated silo or bin opening pressure for initial bin fill condition, as well as flow condition. Design techniques such as tapered openings by 5 degrees divergence, and relieving the feeder angle by a few degrees, assists with minimising pull-out torques.

Thin-wall products can dry in less than 10 minutes, whereas engineered thick-wall protective packaging could take up to an hour to dry. For every pound of dry fiber that enters a dryer, there typically is up to four times as much water by weight, which requires a lot of energy to adequately dry.
Abstract and Figures Conveyor belt dryers have been applied extensively in the drying process even though the problem of uneven drying along the dryer length exist. The general solution is...
