- Packaging and Packaging Materials
The instrumental estimation of Pasteurisation Units (PU’s) by determination of time and temperature and the calculation of Pasteurisation Units in order to control the pasteuriser performance. With computer based overall supervision of the complete packaging line, it is possible to provide control of the pasteuriser and other items of packaging line equipment in response to changes in the whole system. For example, in a packaging line of small containers, in conjunction with the use of variable speed drive of the transport system, it is possible to control transit time and temperature of the pasteuriser to ensure the correct level of heat treatment for each group of containers, as represented by a line of containers across the width of the machine. Pasteurisation is a gentle heat treatment to reduce the microbial load in a product so that there is no micro-biological growth during shelf-life.
