Mixed-Mode Solar Drying and its Effect on Physicochemical and Colorimetric Properties of Zompantle (Erythrina Americana).

A mixed-mode solar drying was developed to evaluate the physicochemical and colorimetric properties of Zompantle (Erythrina americana). A 2-factorial design was used; the operation mode (mesh shade and direct) and airflow (natural convection and forced convection) were established as factors in this design. The initial moisture content in the Zompantle flower was reduced from 89.
