Literature on rotary dryers is primarily focused on design methodology and on fundamental parameters needed to understand the physical phenomena involved in this equipment. in this paper we consider an alternative point of view which representsontribution to the analysis of the performance of existing rotary dryers.
A rotary dryer is said to be of the direct type if, by virtue of its design, heat is added to or removed from the solids by direct exchange between the gas and solids. the direct heat dryers are the simplest and the most economical class. they are used when direct contact with the hot gas or air is not detrimental to the fed.
Mechanism prior to design work is strongly recommended. in drying of wet solids, the following main factors, which essentially are used in process design calculation of dryers should be defined in accordance with mass and heat transfer principles, process conditions and drying behavior drying characteristics. constantrate period.
