An increased number of recent enquiries for food powder applications have promoted Polex to expand their existing range of scrubbers. Polex is now designing their scrubbers to suit a wider range of airflow capacities and dust types to provide more filtration solutions for food powder applications.
When food powders are added to mixers and blenders, air in the tanks is displaced causing the powder to escape at the opening. For companies that have existing water treatment facilities, a wet scrubber system can often be a solution for on-going maintenance. Conventional, dry-type filters can be a nightmare for maintenance due to the hygroscopic nature of food powder, meaning that filters regularly block and must be cleaned. A wet scrubber system, however, can run continuously without blocking. They can then simply be cleaned by hosing out through the access doors. It must be noted however that the company must have an existing water treatment facility in place otherwise removal of sludge and contaminated water becomes an expensive exercise.
