Canning is a method of preserving food in which the food contents are processed and sealed in an airtight container. The food processing usually entails steaming and to achieve a higher temperature (and thus kill more bacteria) the steaming is usually done at a raised temperature. This also reduces the processing period. When the pressure is released prior to sealing the food product into the canisters (“cans”) there can be an emission of steam and small food particulates. The compact RotoClone type W is ideal for this application. There may also be dust where the raw material foodstuff is passed through materials handling and mechanical processing (pealing, cutting, trimming) and again the RotoClone type W is ideal.
