Specialist industrial cleaning company Polar Intelligent Cleaning Solutions has launched a rapid, effective cleaning service for food production machines, equipment and cold stores in the UK.

The service is based on dry ice or cryogenic blasting technology developed in Denmark, allowing production equipment to be cleaned while still in operation. Dry ice blasting uses small, compact dry ice pellets, accelerated in a jet of compressed air. These pellets strike the surface being treated at the speed of sound and their low temperature (-79°C) cracks and loosens any surface coating, allowing the dry ice to permeate it. The dry ice then sublimes (passes from a solid state to vapour), resulting in an explosive effect that lifts the coating off the surface.
