BATON ROUGE 鈥� 海角社区 researchers have invented an automated sensor that could drastically reduce waste for grease and food manufacturers, saving each U.S. industry millions of dollars a year.

鈥淢aking grease is a very complicated process, as much an art as a science. It鈥檚 not as simple as following a recipe,鈥� said Koottaparambil Lijesh, co-inventor and a postdoctoral researcher in the 海角社区 Department of Mechanical and Industrial Engineering. 鈥淕rease exhibits the properties of a solid and a liquid. Grease is formed through complex chemical reactions where its consistency evolves over time. Slight variations in the factory temperature, raw material quality, when mixing in additives and adding ingredients can lead to differences in the final consistency 鈥� how thick or fluid the grease is 鈥� across batches.鈥�

Manufacturers can liquefy grease that is too thick by adding oil, although that may compromise quality. However, grease that comes out thinner than expected is discarded or sold as a lower-grade product.

After each batch is completed, grease makers usually rely on sampling by skilled workers to ensure quality control. Some plant operators can tell if the grease has the correct consistency by how it looks or smells. But it takes decades to attain that level of expertise.

尝厂鲍鈥檚 eliminates uncertainty by continuously tracking grease properties through real-time assessment of accumulated entropy generation (AEG). AEG tracks the energy used in manufacturing 鈥� heating the base oils, thickeners and additives, blending the ingredients and cooling the grease. Energy is lost at every stage.

The 海角社区 system uses AEG to predict the grease鈥檚 final consistency and tell workers when the manufacturing process is complete. If any deviation occurs, the software sends an alert so workers can make corrections. This guarantees the grease doesn鈥檛 have to be discarded or turned into a less valuable product.

Scrapping is a frequent and costly issue for grease makers. The United States produces around 383 million pounds of grease a year. Scrapping, which includes disposing of the waste in an environmentally safe way, adds around 40 cents per pound to manufacturers鈥� costs.

鈥湷⒊П�鈥檚 monitoring system could save the grease industry millions of dollars every year,鈥� said 海角社区 Mechanical Engineering Professor Michael Khonsari, co-inventor of the monitoring system. 鈥淚t is also a very useful training tool for new workers to optimize their product consistency based on the sensor鈥檚 output.鈥�

The market may be even larger for segments of the food industry, he added. The makers of mayonnaise, ketchup, yogurt and peanut butter, among others, must scrap large quantities of their production because of consistency issues.

Lijesh and Khonsari worked with the 海角社区 Office of Innovation & Technology Commercialization (ITC) to patent their invention. They have also successfully field-tested their invention at a large grease manufacturer, so they know their system works at scale.

鈥淲e鈥檙e excited about helping Drs. Lijesh and Khonsari explore the commercial opportunities for this groundbreaking technology. It鈥檚 interesting how their technology crosses various industries involving emulsions,鈥� said Mariel Liggin, 海角社区 ITC commercialization officer.
