Coffee is typically dried on large patios made of asphalt or cement and then transferred to mechanical dryers. The coffee on the drying patios is shifted every 30-40 minutes and is shaped into long rows of no more than 5 cm in height. Next to each row is open ground, which is warmed and dried by the sun. The coffee is then shifted onto the dry portion of the patio, and the section where it was previously is now allowed to dry in the sun .
