The results have been compared with published data from commercial rotary dryers, and predictions compare within 10 of the available data. The methodology can be used to evaluate trends in the behavior of a rotary dryer where the operating parameters vary, and it is useful for the practical engineer, who has to manage several problems commonly.The rotary screen is available in two types, the drum-rotating and panel-running types, which should be selected according to the condition of the installation site. Figure 1. A schematic of rotary screen 2. MECHANISM OF ROTARY SCREEN The rotary screen has a mechanism to scrape the solids (screenings) trapped inside the screen.
Pressurized Superheated Steam Dryer (ExergyPSSD ). Invented in the late ’70s at the Chalmers University of Technology, Gothenburg, Sweden, our world-leading Superheated Steam Dryer uses superheated steam as media for drying of solid materials like paper pulp, sawdust, wood waste, animal feed, wet distillers grain, peat, sludge, tea, EFB (Empty Fruit Bunches), agro biomass, bagasse, sugar.A mathematical model was developed for predicting the drying kinetics of spherical particles in a rotary dryer. Drying experiments were carried out by drying fermented ground cassava particles in a bench scale rotary dryer at inlet air temperatures of 115–230 C, air velocities of 0.83 m s–1.55 m s, feed mass of 50 x2013 500 x2009 g, drum drive speed of 8 x2009 rpm, and feed drive speed.
