简介: |
Food processing operations are very energy intensive and even though in the majority of cases raw materials costs dominate the total cost of the product, in processes requiring baking and frying the energy cost can be a significant proportion of the total manufacturing cost. Energy consumption by these process can also be responsible for a sizeable portion of the total carbon footprint of the product life cycle.
In an era of steadily increasing energy prices and concerns over the environmental impacts of energy use, energy efficiency can offer one of the best approaches to reduce greenhouse gas emissions and improve profitability. In the production of potato crisps, frying consumes more than 90% of the total processing energy requirement so the greatest potential for energy savings is offered by design and control optimisation to minimise heat input to the potato slices and reduce thermal losses. Optimisation of the frying process requires good knowledge and understanding of the heat and mass transfer processes involved and their influence on product quality, safety, product throughput and energy consumption.
报告人简介：Dr Hongwei Wu received his BEng (1st Class Honours, 1998), and PhD (2004) with specialisation in Mechanical and Thermal Engineering from Beijing University of Aeronautics and Astronautics (now Beihang University), China. Then he worked as a postdoctoral research fellow at The University of British Columbia (2004-2006) and University of Alberta (2006-2007) in Canada for 2.5 years, and then he was appointed as an associate professor at Beihang University (2007-2009). Afterwards, he came to UK worked as a research fellow at Brunel University London (2009-2012) and University of Birmingham (2012-2013) for over three years. Dr Wu joined the University of the West of Scotland (UWS) as a Lecturer in the School of Engineering and Computing since August 2013 prior to taking his current post as a Senior Lecturer in the Department of Mechanical and Construction Engineering at Northumbria University, Newcastle, UK. Dr Wu has been getting involved in various funded projects such as EU, EPSRC, NSERC (Canada), and he has published over 70 research papers in leading international journals as well as international conferences. Dr Wu has been a regular reviewer of many leading journals, and he has also served as Technical Program Committee member in a number of international conferences.
