Precise monitoring
September 1st 2005 Dugdale Nutrition has installed two Krohne Optimass Coriolis mass flowmeters to measure the volume of viscous, oil-based materials used for coating animal feed. The instruments ensure products remain within legal definitions and help minimise production costs.
The single straight tube design allows viscous materials to flow freely through, and there are no moving parts.
Coating material is gravity fed from stainless steel heating vats that raise its temperature to between 55 and 70°C. It is then fed through stainless steel pipework to the Optimass and into mixing vessels. The plant is centrally controlled by a PLC that reads pulses from machinery in the factory. Flowmeters have been pre-calibrated to output a pulse for every 0.5kg of material, enabling the company to monitor precisely the amount of coating material used.
