STS Centrifuges

The STS system is a disk-type centrifuge with the efficiency to process entire tanks of juice or wine, including the lees, ejecting solids at such a concentration (~ 95% v/v) that no further product recovery is necessary by lees filter or RDV.

Our STS centrifuges offer our clients a superior method to manage solids and to eliminate the need for racking of juices and wines, thus avoiding consequent product losses and quality-value downgrades.

A key advantage of the STS system over older centrifuges is a very low oxygen pick-up, as low as 0.02mg of oxygen per litre of wine.

• Removes solids from white juice instantly
• Reduced fining and settling time
• No cold settling or SO2 needed
• Removal of yeast to arrest fermentation
• Removes proteins bound to bentonite
• Increased filter life
• Reduce wine loss to lees

• Whole juice
• White wine ex primary ferment
• Bentonite lees
• Arrested ferments, late harvest and
botrytis styles
• Red wine ex primary ferment
• Gross red lees
• Red wine ex malo-lactic ferment
• Wines ex cold stabilisation
• Coarse polishing prior to cross-flow

The STS45 centrifuge is an effective mobile technology for beer clarification too.
