A solar system utilizing a 553-m2 (5950-ft2) array of evacuated tube collectors has been designed to augment the heat supplied by natural gas to a Proctor & Schwartz continuous belt dryer used for processing onions and garlic at the Gilroy Foods plant in Gilroy, California. It has been calculated that the array, which contains 3216 evacuated tubes, will contribute 2.47 × 1012 J/yr (2340 MBtu/yr) to the dehydration process. The system is currently being installed and will be operational for drying in May 1979. This project was sponsored by the U. S. Department of Energy under Contract No. E-(40-1)-5119.
