Rotary Scraper Dryer :
A rotary scraper dryer is a type of dryer used in industrial settings for the drying of pasty, sticky, and viscous materials. It operates on the principle of indirect heating and mechanical agitation to efficiently remove moisture from the material being processed.
Material Input: Wet or slurry-like substances are introduced into the rotating drum.
Scraping Mechanism: The drum’s rotation, coupled with the fixed scraper blades, continuously agitates and moves the material along the drum’s interior surface.
Heat Application: External heat sources, such as hot air or steam, are directed into the drum, initiating the evaporation of moisture from the material.
Moisture Removal: The scraping action, in combination with the applied heat, facilitates moisture evaporation, leaving behind dried material. 
Scraper drum dryer Applications:
Chemical Industry: Used for drying chemicals, pigments, and dyes.
Food Processing: Ideal for starches, grains, and cereal slurries.
Pharmaceuticals: Applied in drying pharmaceutical intermediates, granules, and powders.
Environmental Sector: Utilized for drying sewage sludge and waste materials.
