Relationship between a solar drying model of red pepper and the kinetics of pure water evaporation (1)
- National Univ. of Salta (Argentina)
Drying of red pepper under solar radiation was investigated, and a simple model related to water evaporation was developed. Drying experiments at constant laboratory conditions were undertaken where solar radiation was simulated by a 1,000 W lamp. In this first part of the work, water evaporation under radiation is studied and laboratory experiments are presented with two objectives: to verify Penman`s model of evaporation under radiation, and to validate the laboratory experiments. Modifying Penman`s model of evaporation by introducing two drying conductances as a function of water content, allows the development of a drying model under solar radiation. In the second part of this paper, the model is validated by applying it to red pepper open air solar drying experiments.
