Abstract
Abstract Bulk density of high-sugar-content dehydrated foodstuff is regulated by varying the thickness of the sheet of the said dehydrated foodstuff as it is being discharged from a drum dryer. The thickness of the said sheet is here varied upon varying the angle of attack of the doctor blade in respect to the drum surface of a drum dryer.
