Abstract | The present study was conducted to find a method to separate grape seeds and soft solids from fresh marc at the end of wine-making processes. Interest in these by-products is growing owing to the high content of phytochemicals and other components useful in cosmetic and pharmaceutical industries. A prototype centrifugal separator was developed and its separation performance was evaluated.Four different reel speed rotations (480, 576, 687, and 842 rpm) and two different blade adjustments (Type-A blade with 1.5 mm and Type-B blade with 8.5 mm) were evaluated at the same mass flow rate (350 kg·h−1).Results showed that the separation of seeds from the fresh grape marc using a centrifugal separator is possible and that this could be achieved by setting the optimal rotation speed of the reel (480 rpm) and establishing the best distance between the blades and the cylindrical separator (8.5 mm with TypeB blades). |
