GEA Mechanical Equipment
Decanter Operation
The load on the secondary motor is measured and converted to torque
• the higher the load the higher the torque
• the higher the torque the more solids in the decanter bowl
•the more solids, the higher the torque = dryer cake
• Scroll automatically regulates scroll speed to maintain torque
• Torque is maintained regardless of any change in feed solids

Presentation context
• This presentation was given as part of a workshop on grape and juice processing
equipment convened by the Australian Wine Research Institute (AWRI) at the 15th
Australian Wine Industry Technical Conference in July 2013.
• The main intention of the workshop was to provide attendees with information on
equipment that is new or unusual or that has not been widely used in Australia.
• This and the other presentations given were prepared by equipment suppliers, not by
AWRI, and AWRI does not necessarily endorse the views presented. Before the
purchase of any major winery equipment, AWRI recommends appropriate background
investigations being undertaken; including visits to facilities already using similar
equipment, consultation with independent experts and the performing of in-house trials.
• AWRI received no payment from suppliers for the inclusion of their equipment in the
workshop.
• For any further details on the workshop please contact AWRI Senior Engineer, Dr Simon
Nordestgaard, by email at [email protected].
