Checking the steam network at a carbonated beverage production facility revealed that the steam condensate is not recovered, leading to loss of water and energy. Installing a condensate recovery network is a feasible alternative to conserve natural resources.
It was noted that this dairy and juice company consumes volume of water to rinse the system during the CIP exceeding the benchmarked quantities. Reducing the water quantities over small steps, while monitoring the product quality lead to conservation of water and energy.
Due to the frequent product change over in a dairy to meet the market demand, the company runs CIP to assure suitability of the production line. Reviewing the production plan to assure the suitability of at least one product change without the need of cleaning saves on raw material, water and energy, as well as increases the availability of the production line.
