A major Canadian bread manufacturing company has installed mechanically cleaned filters from Eaton Filtration to improve workplace safety.
Based in Toronto, Ontario, the bread manufacturing facility uses highly pressurised hot water in its bagel making process to offset potential quality problems. The process also requires a filtration system to clean raisins, sesame seeds, bits of dough, corn meal, and other materials out of the hot water.
The existing filtration system consisted of duplex bag filters, which raised concerns for employee safety because of the hazards of manually changing filter bags while working with high water temperatures.
Planning to install a new bagel boiler in its Alberta, Canada plant, the bread maker required a filtering system to clean the recycled boiler water of raisins, sesame seeds, bits of dough and corn meal. Corn meal can create water quality problems if the temperature falls, requiring an expensive and time-consuming water change.
It was important for the water in the bagel boiler to remain at a high temperature, even during the filtering and recycling process. High water temperatures used in the process can be a serious hazard to an operator changing filter bags, especially when pressed for time during the shutdown process when an operator may open up the filter housing while it is still pressurised.
It was therefore, decided to install a filtering system that required less operator intervention than a bag system to ensure employee safety. Decision makers at the Alberta plant wanted a reliable filter without the hazards occasionally associated with bag filter maintenance.
Working with Eaton, the plant manager and maintenance supervisor determined that the Eaton DCF mechanically cleaned filters met their business objectives completely.
The plant installed two Eaton DCF-800 filters on the boiler water recycle line at the Alberta facility. DCF filters successfully removed the raisins, sesame seeds, bits of dough, and corn meal that would adversely affect the final product.
Key benefits of the Eaton DCF-800 mechanically cleaned filters:
- Uninterrupted filtering ensures consistently high water temperatures required to maintain boiler water quality
- Performs self-cleaning action by mechanically scraping collected debris from the filter screen with a disc
- Collection chamber at the bottom automatically purges collected debris without halting production
- Enables continuous cleaning of the screen without interrupting production
- Maintains consistently high flow rate and provides high quality filtering of bagel boiler water
- Automatic media cleaning with no bags to remove eliminates risk of operator injury related to changing filter bags
Happy with the performance of the DCF filters at its Alberta plant, the company has now installed the filters at its Langley, British Columbia facility for bagel boiler systems.
