CONTINUOUS CONDUCTIVE HEAT TRANSFER DRYER HAVING IMPROVED TREATED OBJECT DISPERSING PERFORMANCE AND ITS OPERATING METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a novel continuous conductive heat transfer dryer having improved treated object dispersing performance for performing good drying operation when handling treated objects such as sludge having high moisture, and to provide its operating method. PSOLUTION: In a body shell 10 or a multitubular heating pipe 11, a mechanism is provided for returning the treated objects H from a discharge side to a charge side. The treated objects H being well dried, located in the body shell 10 at its discharge side, can be mixed with the treated objects H not being well dried, located at its charge side. The treated objects H having high viscosity and poor dispersibility because of high moisture can be put into the condition that they have low viscosity and good dispersibility.
