Pneumatic Cassava Dryers

Low-cost mechanized drying of cassava using Flash Dryers

The equipment "Mechanized Drying of Cassava using Flash Dryers (Pneumatic Dryers)" is a vital component in the cassava processing chain. The process involves the wet product entering the drying duct and being carried by a hot airstream, utilizing negative or positive pressure conveying systems in pneumatic dryers. As the material is transported, heat is transferred to the particles, drying the material as it moves through the system. A cyclone is commonly used at the end of the drying duct to separate the dry product from the drying air. The technology's large surface area of product particles allows for high drying rates and short residence times, facilitating the drying of heat-sensitive materials at relatively high temperatures without overheating. The flash dryer is comprised of a feeding point, a drying duct carrying cassava grits dried by a hot airstream, an air blower, and a cyclone for separating the dried material from the drying air. This innovative technology significantly aids in efficiently and economically converting cassava into higher value-added products like starch and high-quality cassava flour, revolutionizing the cassava processing industry.
