Rotary dryer in a study based on participatory principles for smallholder scale drying

Small farmers who mostly live in rural areas need a cheap and easy technique for the post-harvest production process, especially drying. The participation of is very much needed so that design work tools according to their needs use can be sustainable. So far, sun drying dependent on weather causes fatigue due exposure. To overcome this, dryer was designed with application participatory principles which part ergonomics application. With principle, rotary type developed grain Energy sources rice husks, are widely available they obtain inexpensive. rotary-type utilizes this biomass by energy conversion using heat exchanger. It hoped tool operate it accepted small farmers. In addition, do not experience additional workloads exposure has an impact risk fatigue, increasing productivity.
