‘Powderblue’ blueberries dried faster than ‘Brightwell’
varieties. Drying method, drying temperature, cultivar, pick time,
grade and their specific interactions showed significant influence
on the overall quality of dried blueberries. However, the overall
quality of impingement dried blueberries was comparable with the
control methods. Air impingement drying showed promise for
drying Rabbiteye blueberries as an alternative to other commercial
drying methods. Further improvements of air-velocities of
impingement dryer to a level of 4e6 m/s might help to match up
with the drying time of the Jet-zone fluidized bed dryer.
