Coffee beans can be dried in the sun or by machine.
Coffees dried in the sun are spread out on patios or on raised tables made of coarsely woven matting or screens. Coffee on patios needs to be raked every 6 hours to prevent mildew and ensure even drying. Coffee dried on raised beds has the advantage of better air circulation for more even drying. It is often turned by hand. Sun drying can take up to 4 weeks.
