Sažetak
The drying characteristics of celery root (Apium graveoleus var. rapaceum) were investigated using a bench-scale fuidized bed drier at different temperatures and different pre-treatments. Celery root was cut into rectangle-shaped samples 20x20x5 mm in size. Temperatures of fluidisation for non-treated samples have varied from 50 &ordm ; ; ; ; ; ; C to 80 &ordm ; ; ; ; ; ; C at airflow velocities of 3.50 m/s. Before drying at 80 &ordm ; ; ; ; ; ; C, samples were pre-treated either thermally or chemically, or both (blanching in hot water, dipping in 1% ascorbic acid solution, blanching in boiling 2% CaCI2 solution, dipping in 2, 5% starch solution). The aim was to obtain celery root with approximately 7% water content, with good texture, rehydration capability and colour quality. The effect of temperatures and pre-treatments on the quality of dried celery root samples was determined on the basis of colour and volume changes and reconstitution characteristic
