Apstrakt
Sprej sušare se veoma često primenjuje u hemijskoj i prehrambeno - prerađivačkoj industriji. Ova metoda sušenja podrazumeva suspenziju sa sadržajem oko (30 do 40) % praškaste materije. Period sušenja u većini slučajeva je samo nekoliko sekundi. Sredstvo za sušenje je topli vazduh. U radu su prikazana eksperimentalna i teorijska ispitivanja sprej sušare skrobne suspenzije sa 30% i 40% suve materije. Prenos toplote se ostvaruje konvekcijom, zahvaljujući principu sušenja zasnovanom na direktnom kontaktu zagrejanog vazduha i vlažnog materijala. Tokom tog procesa dolazi do intenzivne razmene toplote i mase. Na osnovu rezultata istraživanja dati su modeli sušenja – temperaturna kriva sušenja, kriva brzine sušenja i temperaturna kriva vlažnog materijala.
