ABSTRACT
The trials have been carried out in a laboratory spouted bed drier. Measurements of changes in water content in the envelopes of yeast slurry dried on glass spheres have been made. The drying was performed at inlet air temperature t = 90°C and the thickness of the slurry envelopes on the spheres b ť 0.2 mm. Air velocity in the cylindrical part of drying chamber ranged from 2.6 m s-1 to 4.6 m s-1. The influence of air velocity on drying rate and the value of average moisture flux from a unit area of inert spheres have been determined.

Doświadczenie przeprowadzono w laboratoryjnej suszarce fontannowej. Mierzono zmiany zawartości wody w otoczkach gęstwy drożdżowej suszonych na szklanych kulach. Suszenie prowadzono przy temperaturze powietrza na wlocie t = 90°C i grubości otoczki gęstwy na kulach b ť 0,2 mm. Prędkość powietrza w części cylindrycznej komory suszenia regulowano w zakresie 2,6-4,6 m×s-1. Określono wpływ prędkości powietrza na szybkość suszenia i wielkość średniego strumienia wilgoci z jednostki powierzchni kul inertu.
