In-plant hygiene and Best Manufacturing Practice place an ever greater emphasis on air quality within the manufacturing environment. From handling of raw materials to the production process, there are many applications that require dust control to maintain a high standard of cleanliness and to ensure the health and safety of employees. Many confectionery ingredients have the potential to create explosive dust clouds, so ATEX issues must be addressed. Often confectionery factories have limited indoor space for bulky bag filters which must be either outdoors or be positioned to vent their explosion relief panels to outdoors. A neat solution, especially suitable for sugar dust, is the RotoClone W, which is inherently safe and whose compact dimensions allow in-plant installation as close as possible to the nuisance dust source, thus minimising ductwork and reducing maintenance. Its long service life, simplicity and quiet, efficient performance make the RotoClone W an ideal choice. For raw materials handling and other applications where dry filtration is preferred, AAF will offer a unit from our extensive bag filter range or the new OptiFlo RC cartridge filter.
