Abstract

During cassava processing, the roots are peeled, washed, and grated into a mash. The mash is subsequently mechanically dewatered with a press, and the obtained press-cake is pulverized into wet cassava grits. The wet cassava grits are then introduced to the dryer, and the obtained dried grits are lastly milled into cassava flour. When cassava is processed using a pneumatic dryer, the wet cassava grits need to be introduced to the drying equipment uniformly, and in a free-flowing form, with no lumps. However, wet cassava grits have poor flow properties and are highly cohesive, with the tendency to agglomerate into lumps. In previous work, the required features of a feeding system for cassava pneumatic drying was investigated. The work considered the flow properties of wet cassava grits and the specificities of how the material should be fed into a pneumatic dryer. It was determined that such a feeding system should have a hopper with vertical walls, equipped with a flow aid device, and a feeder with a screw mechanism, equipped with a disintegrator.
