The high performance disc clarifier from STS was designed for high solid feed processing.

Built specifically to concentrate solids and clarifier feeds such as wine, juice, green beer, wort, cider, kombucha, tea, plant based protein isolates, etc. It's sanitary and rugged design is a perfect solution for your clarification needs.

STS has moved into a new & larger 9,000 sqft. facility in the Bay Area (located at 2591 Nicholson St, San Leandro CA 94577), providing Parts, Service, Sales & Admin now all under one roof.

Separator Technology Systems USA Inc’s new location comes at an excellent time as STS has been appointed the authorized sales, parts & service agent for KMA centrifuges.  KMA centrifuges are well known in the USA wine industry, with many GTS 180’s offering many years of reliable service at Bronco & Woodbridge.

As well as expanding our service s – STS has also added new personnel:

STS welcomes Dempers Boonzaier as Snr Service Technician, an internal company promotion from our South African subsidiary. Dempers Boonzaier, a first point of call for Service on your STS, KMA or GEA or Alfa Laval centrifuge.

STS has appointed Anja Webster as After-Market Parts Manager.  Anja joins us from Andritz (nee Contec) and is the best point of contact for STS’s range of genuine, OEM & compatible spare parts to suit GEA & Alfa Laval centrifuges – with considerable savings - as well as genuine spare parts for KMA centrifuges.

 The STS 45 system is claimed to be a superior method for winery solids management and eliminates the need for racking of juices and wines and therefore avoiding consequent product losses and quality-value downgrades.

State-of-the-art centrifuge system 

• Reduce fining and settling time, increase filter life and reduce wine lost to lees.
• Remove solids from white juice instantly.
• No cold settling or SO2 needed.
• Remove yeast to arrest fermentations.
• Speed up fining.
• Protein bound to bentonite removed efficiently.

Central to the system is the STS 45, a disk-type centrifuge with the capability to both process entire tanks of juice and wine, including the lees, and eject solids at such a thickness (e.g. 95% v/v) that no further product recovery is necessary, e.g. lees filter or RDV filter.

The three principal paybacks and quality outcomes with the STS 45 are:

• 1. Reducing juice and wine losses associated with racking or desludge from older or under-performing centrifuges. Losses occur when lees are sent to distillation and through reduced number of lees transfers; both leading to dilution or yield losses.
• 2. Reduced juice and wine quality or value downgrades. This is where existing lees handling processes lead to loss of quality and value by loss of freshness and oxidation, loss of varietal or regional integrity and character, or anoxic/reduction taints from prolonged exposure to high concentration of yeasts and bacteria in lees.
• 3. Eliminating DE filtration, principally the lees filter and rotary drum vacuum (RDV) filtration. The direct hard savings in reduced DE consumption are typically modest in the financial justification of the STS 45 mobile service.

A key advantage of the STS 45 system over older centrifuges is a very low oxygen pick-up, as low as 0.02mg of oxygen per litre of wine. This means the same wine can be centrifuged multiple times during its maturation cycle. The low oxygen pick-up allows  cellars to maximise the financial benefits of ST 45's broad spectrum of juice and wine solids removal capabilities.

The STS 45 system has been developed to handle a broad range of winery products.

• Whole wine juice
• White wine ex primary ferment (including bentonite lees)
• Bentonite lees
• Arrested ferments, late harvest and botrytis styles
• Red wine ex primary ferment (including gross lees)
• Gross red lees
• Red wine ex malolactic ferment
• Wines ex cold stabilisation
• Coarse polishing (prior to cross-flow)

Proactive attention to solids during the winemaking process improves cellar production efficiencies.

Winemakers rarely give product solids management much thought except that they wish to have them remove before bottling. Yet by proactively managing solids, it is possible to improve cellar production efficiencies, reduce product losses and downgrades, and produce wines of specific styles.

Separator Technology Solutions is a wine industry centrifuge specialist with tried and tested expertise that grew out of the Australian wine industry. Operating in Australia, USA, France, Chile, New Zealand and in South Africa since 2006, STS is fast becoming the global wine industry centrifuge standard.

STS is overseen globally by Ashley Whittington, based in the USA office, with the South African team operating from its dedicated facility in Somerset West.
