Process Heat Case Study
Voyager Craft Malt

Voyager Craft Malt produces malt for craft brewers and distillers using their own locally grown and regionally sourced cereal grains. This boutique malt house is located at Whitton in the Riverina, NSW.

The Issue

The company prides itself on using sustainable agricultural practices to grow the grains that goes into their malt. It was equally important for Voyager Craft Malt to find a cost effective, environmentally responsible heat source for malt production.

The Alternatives

The company compared the use of LPG with the use of Pyrocal CCT to produce heat.

Voyager Craft Malt, Pyrocal

The Solution

The Pyrocal CCT system was selected to provide the heat source for kilning. Locally sourced walnut shells provide the biomass for the Pyrocal CCT system to generate the energy. This is achieved without burning fossil fuels.

Conveniently, the process also results in biochar that is on-sold for a wide variety of uses.

The Results

Voyager Craft Malt commissioned the larger of their two existing malting systems in September 2016.  This malting system is integrated with the Pyrocal CTT system on site which provides ~500kw of heat for malt kilning needs. 

The net annual savings are $54,000 or a 60 percent reduction in heat costs, compared to using LPG.

Voyager are looking to expand production by upgrading with a second CCT system or replacing the existing system with a higher output model.

The energy from the production of the bio-char is used to heat the kilns in the malt house. We would struggle to have a viable business model without it.
Having this unique heat source also allows us even more flexibility in flavour and aroma management.
