A company wanted to reduce the amount of vegetable oil waste they were producing in their potato chips (crisp) batch frying process. They were using 30,000 liters of vegetable oil per week to fry their potato chips. The company wanted to manage the amount of oil they were using by prolonging the usable life of the oil and eventually reducing the waste volume to zero in their chip batch frying process by dosing the oil with an oil purifying agent.

To do this they were dispersing a fine, white food-grade powder called Dalsorb, a magnesium silicate, into the hot sunflower oil. The company contacted Silverson to discuss what could be done to improve this process and which mixer from the product range would be the most appropriate and safe due to the hot oil in the process.
