Ceramic IR Raisin Drying

The team's objective was to find an alternative to drying raisins with natural gas ovens. Our proof of concept was successful, and there is a possibility of industrializing the process one day.

Raysun Team

The RaySuns team is excited to present our 2019-2020 interdisciplinary senior project. The team worked hard to develop a functioning prototype that will one day change the raisin drying process by making it more sustainable and efficient.
