Process optimisation was the theme of The Society of Dairy Technology's autumn symposium in Wales, the UK. The first speaker was Dr Hassan Yasdi of GEA, who discussed sustaining the benefits of process optimisation, using spray powder manufacture as the prime example. Most processes are at risk from instability, whether from the feedstock, environment or process. In these circumstances the operators tend to take a less productive, 'safe and easy' approach. In seeking to optimise a process, the first step is to achieve stability, for instance by standardising lactose to milk protein ratios in the feedstock, to achieve consistent quality in the powder. Once stability is achieved, then optimisation can lead to higher productivity.
