When you last snacked on some almonds, you may not have given much thought to how they were harvested and made ready for your consumption. However, like almost all food and beverages, on their journey to your snack bowl they encountered some stainless steel bearing equipment.
The aim of AS 1528: Stainless steel tubes and tube fittings for food processing and hygienic applications is to standardise hygienic tube and fittings for use in dairy, food and beverage manufacturing. It has been successful in maintaining the required food safety standards in Australia and New Zealand.
The new facility in Merrifield Estate on Melbourne's outer northern fringe will allow Dulux to step into the next generation of paint manufacturing technology and innovation. Dulux's aim was to design and construct a state-of-the-art facility, so using quality products was essential to achieve this. Stainless steel in 300 series grades was an integral part of the project design, including storage vessels and over 10,000m of food grade, quality tube complying with AS1528.
Wave Discs Revolutionises Traditional Drying Process
In the search to find a more efficient way of manufacturing industrial disc dryers for the meat-rendering industry, Melbourne-based engineering company Pinches Group has developed a new technology called Wave Disc.
Connections are vital
Any visit to a dairy, beverage or food processing plant will drive home the critical importance of the connections between the tanks, mixers, driers, pumps, etc. The image above (courtesy of TFG Group) showing an image of a brewery is a typical example. These tubes and/or pipes carry the process materials, the heating or cooling or wash water, gases, and also dispose of the wastes.
This is an abridged version of a story that first appeared under the same title in Stainless Steel Focus No. 07/2012.
The Nickel Institute's director of promotion, Peter Cutler, and consultant Gary Coates, reveal some of the reasons for the continuing popularity of nickel in stainless steels.
Stainless steel is everywhere in our world and contributes to all aspects of our lives. We find stainless steel in our homes, in our buildings and offices, in the vehicles we travel in and in every imaginable industrial sector. Yet the first patents for stainless steel were issued only 100 years ago.
How did this metal become so desirable over the past century that more than 32 million tonnes was produced in 2011? And how does nickel, a vital alloying element in most stainless steel alloys, contribute to the high demand for stainless steel?
A worrying trend among Australia's major resource companies is the increasing amount of engineering, detailing and fabrication work being sent offshore - a move that has had significant impact on local fabrication. But there are some positive signs in the food and beverage sector that local fabricators are more than capable of meeting design and fabrication expectations.
Stainless steel forms a significant part of a beef abattoir, including the conveyors, fixed and elevated platforms, sterilisers, chutes, hand wash basins and, of late, water supply and wastewater piping. The stainless component may now expand even further in new abattoirs with the recent development of cast stainless steel skids and forged hooks for use on dressing conveyors.
