In the lead-up to the 2007 Winery Engineering Association conference and exhibition, ‘Progressing through engineering’, Daily Wine News is taking a further look into the presentations to be held over the two day event.
Below is a selected list of abstracts to be presented.
Value adding life to centrifuges (training course information for maintenance & operational staff)
Jason Harris, Westfalia Separator
With over 150 Westfalia Centrifuges operating throughout the wine industry, Westfalia Separator recognized the need for on-going training in order to support the Wine Industry. Various training methods have been tried over the years, with varying levels of success. After a thorough review of past techniques it became obvious that two forms of training is required; operator and maintenance training.
An assessment of the techno-economic feasibility of large-scale microalgal lipid production for biofuels
David Lewis PhD BE(Chem), University of SA
The biodiesel industry in Australia is currently undergoing significant expansion due to a number of factors which include increasing demand, recent peaks in crude oil prices, the availability of lower-cost manufacturing plant, and government support in the form of capital grants and tariff relief. But perhaps the biggest risk to the fledgling local biodiesel industry is the availability of low-cost feedstock in sufficient quantities. This paper presents the view of the technical and economic feasibility of one process option for meeting the challenge of producing large quantities of microalgal lipids at low cost.
Boreal: Cold pre-fermentation maceration
Don Allen, Air Liquide
The Boreal unit is one element in an innovative cold pre fermentation maceration (CPM) technique in the vinification of red (or white) wine which may be introduced in order to influence the quality of the wine produced. CPM is a treatment which consists of delaying the commencement of alcoholic fermentation by means of cooling the crushed grapes by direct injection of liquid carbon dioxide.
Duty of care associated with operating ammonia refrigeration plants
John Rodda & Craig Willis, AIRAH & Work Safe Victoria
A recent analysis conducted by Work Cover showed that anhydrous ammonia was named as the third most hazardous material commonly found in Australian workplaces, with LPG and petrol being the first and second. The risks of using ammonia can be greatly minimised, however, with proper training and work practices. This presentation will cover issues pertaining to running an ammonia refrigeration plant and the ‘duty of care’ that needs to be taken by companies to ensure that they and their staff are fully compliant and prepared for an ammonia leak.
Efficiencies associated with cardboard carton design
Peter Stevanz, Amcor
Cardboard cartons are used throughout the wine industry in many areas, for a wide range of purposes. In most cases, awareness of the various options and their application in gaining efficiencies is not widely known. The relationship of carton style and shape can provide surprising results when examined closely.
Arriving at a balanced carton which delivers the product safely to the end user, without compromising bottling line efficiencies is the key objective. Raising awareness of each of the components necessary and what may be done to assist in the final outcome will be presented in this paper.
Evolutions of winery grape juice extraction
Paul Baggio, Australian Winemakers
Australian Winemakers has been evaluating a technology that was invented back in the late sixties. The central membrane press as much as it may seem revolutionary is in fact based on principles that were first modelled over fifty years ago. The design logic bases itself around achieving the fastest juice separation from grape skins so as to ensure an extracted juice very low in poly phenol concentration, as is required for sparkling wine production. Today the central membrane press dominates a great part of the European winery landscape and is making significant impact on the new world.
Water recovery for beneficial re-use
Ian Lilley, Barry Brothers
Barry Bros have been recovering water for re-use for 4 years and what started as an exercise in waste reduction has evolved into a driving force in the company and amongst customers. Barry Bros are pursuing options to recover some of the 97–98% water content in sewage, treat it locally returning sewer solids to the sewer and deliver it to re-use customers at standards fit-for-purpose.
Energy efficiency across winery services
Nitin Joglekar, Beca Pty Ltd
In a winery, major energy users are the services such as refrigeration, compressed air, heating and pumping. With associated facilities such as bottling and warehousing, air-conditioning and lighting are additional services, which consume a fair chunk of energy. The paper aims to provide an overview of energy efficiency improvement options for these services.
The 2007 Winery Engineering Association conference and exhibition will be held in Mildura on the 20–21 June. For further information visit http://www.wea.org.au
