Abstract
A co-current laboratory spray dryer was designed to meet multipurpose requirements for drying
food materials and constructed from relatively cheap locally available materials. Tests, on the
basis of 100% moisture were carried out to characterise the equipment and milk was dried to
determine the particle size distribution.
The dryer efficiency at optimum conditions, varied between 44.7%-59.7% and the average
particle size was 10ym - 20um. The highest temperature of the air possible for drying was 413K
while the lowest was 355K and the maximum air flow rate in the chamber was 31 litres/minute.
The drying rate was 0.65g/min and, the maximum relative humidity of the outgoing air at the
minimum temperature was 96%.
