Improvements in sustainable energy and water practice in the food processing industry : an in depth analysis of the manufacture of Ghee at the Butter Producers' Cooperative Federation Limited, Brisbane

This thesis is a documented energy audit and long term study of energy and water reduction in a ghee factory. Global production of ghee exceeds 4 million tonnes annually. The factory in this study refines dairy products by non-traditional centrifugal separation and produces 99.9% pure, canned, crystallised Anhydrous Milk Fat (Ghee). Ghee is traditionally made by batch processing methods. The traditional method is less efficient, than centrifugal separation. An in depth systematic investigation was conducted of each item of major equipment including; ammonia refrigeration, a steam boiler, canning equipment, pumps, heat exchangers and compressed air were all fine-tuned. Continuous monitoring of electrical usage showed that not every initiative worked, others had pay back periods of less than a year. In 1994-95 energy consumption was 6,582GJ and in 2003-04 it was 5,552GJ down 16% for a similar output. A significant reduction in water usage was achieved by reducing the airflow in the refrigeration evaporative condensers to match the refrigeration load. Water usage has fallen 68% from18ML in 1994-95 to 5.78ML in 2003-04. The methods reported in this thesis could be applied to other industries, which have similar equipment, and other ghee manufacturers.

Emprego da energia solar para pré-aquecimento de água de reposição de caldeira.

Apresenta-se uma avaliação técnico-econômica para o préaquecimento solar da água de reposição em caldeiras de sistemas de vapor abertos. São empregados, para compor um estudo de caso, os dados de uma indústria de laticínios de médio porte situada próximo da cidade do Rio de Janeiro. Quarenta e oito simulações computacionais do sistema de aquecimento solar (SAS) foram realizadas em TRNSYS, correspondendo aos 5% melhores resultados econômicos de uma série de 2.700 simulações mais simples (método φ-f-chart), programados em MATLAB. Foram empregados dados horários de ano típico meteorológico (TMY) para a cidade do Rio de Janeiro. O ganho econômico foi baseado no consumo evitado dos três combustíveis mais comuns na indústria de laticínios, enquanto o custo de investimento foi composto a partir de valores comerciais e da literatura. Os resultados da avaliação econômica mostraram-se desfavoráveis para a substituição de óleo combustível, favoráveis no caso de caldeiras a gás natural, condicionado a existência de subsídios, e bem competitivos para a substituição de GLP. A eficiência térmica do sistema mostrou ser o parâmetro técnico chave para o desempenho econômico, consequentemente, uma vez que a eficiência se mostrou inversamente proporcional tanto ao volume do reservatório quanto à área de coletores, não há uma configuração ótima para o sistema. Não obstante, os resultados permitiram a proposição de políticas públicas para incentivar o uso da energia solar na indústria leiteira e, consequentemente, contribuir para a preservação ambiental.

Improving boiler performance with modified boiler control systems

For timely processing of the crop, sugar factories need boiler stations that can reliably produce steam when fired with fuel of variable quality. The control systems installed on most sugar factory boilers have changed little in the last thirty years and in some cases the default control system response to changes in fuel and/or fuel quality is not correct and operator intervention is required to prevent factory stoppages or reductions in crushing rate caused by poor combustion. Some factories have recently modified their boiler control systems for improved combustion performance and reduced maintenance costs. This paper describes testing carried out to evaluate some of these control system modifications and identifies boiler control system changes that can be applied more widely in the sugar industry.

The effects of gas and air flow distributions on the performance of the Farleigh No. 3 boiler

As more raw sugar factories become involved in the manufacture of by-products and cogeneration, bagasse is becoming an increasingly valuable commodity. However, in most factories, most of the bagasse produced is used to generate steam in relatively old and inefficient boilers. Efficient bagasse fired boilers are a high capital cost item and the cost of supplying the steam required to run a sugar factory by other means is prohibitive. For many factories a more realistic way to reduce bagasse consumption is to increase the efficiency of existing boilers. The Farleigh No. 3 boiler is a relatively old low efficiency boiler. Like many in the industry, the performance of this boiler has been adversely affected by uneven gas and air flow distributions and air heater leaks. The combustion performance and efficiency of this boiler have been significantly improved by making the gas and air flow distributions through the boiler more uniform and repairing the air heater. The estimated bagasse savings easily justify the cost of the boiler improvements.
