Problem: Golden Acres Petfoods makes 5000 different premium pet food products. As part of its expansion plan, the company will raise production from the current 1500 metric tons of dry extruded pet food a week to 2500 metric tons and needed more capacity to extract the hot odorous gas produced during the cooking process. The three fans in the newly built extraction plant had to be powered as efficiently as possible.
Solution: ABB?high efficiency IE3 class motors will save the company £26,000 per year on energy costs for the new odour control facility.
The new extraction plant takes odour from the process lines as well as providing general extraction for the production buildings. Two of the three fans in the fan house handle the extraction of the process gas and are powered by two ABB?IE3 motors, while all the building ventilation volumes are brought together to a single fan powered by a 250kW ABB?IE3 motor. When fully operational the system will extract 500,000m3 of air from the factory every hour.
Jim Whittaker, engineering director at Golden Acres explained the difference made by using high efficiency motors in place of standard motors: “The higher efficiency of the IE3 motors gave a lower energy usage of 851kW, producing a total running cost per year of £386,013, a saving of nearly £26,000 a year over the standard efficiency solution.”
