Título del libro: Ids'2018: 21st International Drying Symposium Título del capítulo: Moisture content modeling and effective moisture diffusivity determination during convective solar drying of blackberry (rubus spp) and basil (Ocimum basilicum L.)
Solar Collector for air heating; solar energy; variable conditions
Resumen:
The goal of reducing energy consumption (EC), losses and waste (FL) in
the food processing is a challenges in the worldwide. The use of active
solar greenhouse dryers (GHD) for EC and FL reductions has increased due
to its capacity, and low operating costs. In this work the effective
diffusivity (Deff) and the moisture content modeling were analized for
basil (Ocimum basilicum) and blackberry pulp (Rubus rosoideae) dried in
a conventional stove (CD) and an GHD coupled to an additional air solar
heating system (SCHa). The loss of water and the drying rate in food
materials dehydrated in the GHD is consistent with the increment or
decrement of temperature during the solar day. The D-eff values for
basil and blackberry pulp was ranged between - 1.1044x10(-7) and -
3.9167x10(-9). The solar energy obtained in the GHD supplied the heating
requirements. In general, the Page's model was the best fit for the
drying kinetics for basil and blackberry pulp.
