heal.abstract	The drying of Sultana seedless grapes was investigated under intermittent and continuous operating conditions in a laboratory solar installation involving a thermal storage bed and an auxiliary heater. The effect of pretreatment, and of the air velocity on the drying rate of the grapes at constant temperature was also studied in relation to the quality of the dried product. Solar drying of the grapes was accomplished in 30. 5 to 60. 5 h of intermittent operation, or 19 to 60 h of continuous drying, involving the thermal storage bed and the auxiliary heater. The shortest drying time (19 h) and the highest quality dried product were obtained with grapes dipped in a hot (80 degree C) solution of sodium hydroxide and ethyl oleate, which were dried continuously at 42 degree C and 2m/s, air temperature and velocity respectively.	en
