ABSTRACT:
Spray drying coffee extract by uniformly fluctuating the extract and concomitant inert gas flow through the drying tower spray nozzle produces a unique agglemorate-type product. A two-fluid ventur-type flowrator is employed to assist regulation of extract flow rate cycles between set maximum and minimum values. Smaller, quickly drying droplets, atomized at high flow rates of extract are caused to impact with the larger, slower drying drop (minimum extract flow rate) by the reported expansion and collapse of the spray pattern and the augmentation of turbulence by the cyclic inert gas flow rate.
