The Aberdeen headquartered company successfully trialled a pilot microwave sensor scheme at its UHT plant, which produces ambient foods such as savoury sauces and dairy products.
Macphie currently uses timer-based technology to flush the pipes at its processing facility with water for cleaning between products. However, the system relies on the timers to judge when a product is no longer being processed.
Detect within a second
The microwave technology, which was developed in conjunction with Scotland’s Innovation Centre for Sensor and Imaging Systems, can detect, to within a second, the presence of a product in the processing line and will displace cleaning water.
“This project is a significant step and allows us to be more flexible,” said head of research Ashley Baker.
