Raisins that have been formed by field drying of grapes and that have been exposed to rain during the drying process that has caused solids, particularly sand, to become embedded in the surface folds of the raisins, are cleaned of such embedded solids by spraying with a mixture of pressurized air and water applied through an atomizing nozzle, which achieves both washing and drying of the raisins. The same process is applicable to other agricultural products with wrinkled skins, and produces unusually effective results. |
