solar food dehydration, convection flow
A solar food dryer, previously developed for personal and small community use, was the object of this optimization study. Based on previous research of convective solar food dehydrators, several dryer parameters were identified for this study. Chimney height and dryer product load were two factors tested in a central composite experimental design. Dryer product load was found to produce a maximum efficiency of the dryer when fifteen product-filled trays were inserted in the dryer. Maximum efficiency was observed at the maximum chimney height tested. Post-optimization configuration compared with pre-optimization configuration resulted in a 40% increase in final dry product production per hour of dehydration time.
