Various approaches to both modelling and control in food processing are set in the context of the specific challenges in this industrial sector and latest developments in each area are discussed. Three industrial case studies are used to demonstrate the benefits of advanced measurement, modelling and control in food processes. The first case study illustrates the use of knowledge elicitation from expert operators in the process for the manufacture of potato chips (French fries) and the consequent improvements in process control to increase the consistency of the resulting product. The second case study highlights the economic benefits of tighter control of an important process parameter, moisture content, in potato crisp (chips) manufacture. The final case study describes the use of NIR spectroscopy in ensuring effective mixing of dry multicomponent mixtures and pastes. Practical implementation tips and infrastructure requirements are also discussed.

Industry placements in chemical engineering formation

With increasing numbers of young people wishing to study chemical engineering, a key challenge is to ensure a sufficient number of opportunities for the students to gain industry exposure which is a vital part of chemical engineering education. A number of surveys were sent out world-wide to chemical and process companies, academic institutions offering chemical engineering programmes and to current students. The results of these surveys form the basis for this contribution, revealing common trends relating to the effectiveness of industrial exposure regardless of geographical influence. Drawing on experiences from a number of universities, the presentation will show examples of good practice in creating placements and internships which deliver value to the students and to the employer while being amenable to academic assessment. Views of students and placement providers complement the good practices identified through consultation with the academic community. They reinforce the common themes identified as important in providing a high quality of industrial exposure. The work forms part of IChemE's programme to increase both the quality and quantity of such opportunities for the profession in the future.

Computer aided delivery of case-based learning activities in EBL within chemical engineering curriculum

Computer aided learning packages play an important role in this process, as they enable students to explore and gain experience of new software environments in subject specific context. The development of case studies delivered in Stages 1 and 2 and utilising a number of different software packages is described. The Stage 1 case study develops fundamental principles of chemical engineering (mass and energy balances, reaction kinetics, heat transfer, sustainability) whilst Stage 2 case studies concentrate on separation processes and the reactor engineering aspect at the same time requiring the application of the knowledge of statistics and design of experiments, respectively. Student evaluation via questionnaires, focus groups and comments from individual reflective reports, submitted as part of the evaluation of the Stage 1 case study activity, demonstrate the impact of these case studies on student learning and their behaviour. Students consider these case studies very useful in strengthening their knowledge of the relevant areas of chemical engineering curriculum as well as helping them develop skills they consider important from employability point of view. Their suggestions for further improvements have been implemented during summer 2011 and a new, student-centred self-help tutorial on HYSYS will be available for the new academic year.

A structured mechanistic model developed previously was available but this model failed to account for the effects of low levels of dissolved oxygen on growth and production. When moving towards optimising the fermentation, dissolved oxygen becomes the parameter limiting process productivity and hence it is important to be able to account for its process influence. Terms predicting dissolved oxygen changes and describing its effect when at low levels were included in the model to compensate for the reduction in growth and production. Even so, the natural variation experienced in the fermentation resulted in process / model mismatch. On line correction of model coefficients via an observer approach provided the accuracy required for optimisation purposes. The improvements in the accuracy of the model predictions are demonstrated.

The need to utilise both algorithmic and rule based fault detection methods is discussed. Following this, the implementation strategy based on the use of G2 from Gensym is outlined. The KAT knowledge elicitation method was used to efficiently capture the fault detection rule set. Examples of the method of elicitation, form of the rules and ease of implementation are given. Finally, the integration with multivariate data-based methods for fault detection and process application of the combined system is described.
