Air flow characteristics of parchment coffee beans
A knowledge of the air-flow characteristics and the effect of moisture content on the bulk density and angle of repose of wet drained parchment coffee is of interest in pneumatic conveyance of the material; the apparatus and the methods used in determining these values are described. In an attempt to skin dry the wet drained coffee during pneumatic conveyance by pre-heating the air it was found that due to the fairly high bean velocities obtained from minimum air velocity requirements, such a drying technique is not practicable. The characteristics of Arabica and Robusta coffees, the two varieties grown in East Africa, are found to be different
