摘要

The present invention relates to a control method for filter replacement of fluidized bed dryer and, specifically, to a control method for filter replacement of fluidized bed dryer which comprises steps of: determining operation state of a motor; rotating a rotary plate in right direction or reverse direction according to the operation of the motor; calculating distance that a wire is reeled or released by detecting rotation of the rotary plate using a sensor; and displaying filter information on a screen by using the calculated value. The control method for filter replacement of fluidized bed dryer facilitates replacement or cleaning of the filter and prevents negligent accidents during replacement of the filter.
