Processing tomatoes were obtained from grower collaborators
participating in a University of California, Davis tomato variety evaluation
project. Tomatoes were grown from transplants and watered
with subsurface drip irrigation and standard commercial practices.
Healthy, red ripe mature tomatoes were selected by hand, then washed
and cut into 5 mm thick slices. The sliced fresh tomatoes were weighed
on a scale before being placed onto the top and bottom drying racks within two solar dryers, and were weighed again on two hour intervals
during drying trials.
