Abstract
:1. Introduction
2. Materials and Methods
2.1. Data and Knowledge Collection
2.2. Application Description
- the moisture content at any time dry basis (d.b.) and the moisture content at any time wet basis (w.b);
- the mass of moisture removed from the fresh product, the drying ratio, the latent heat, the sensible heat, and the overall heat required to evaporate moisture from food;
- the heat input to the solar collector, heat useful from solar collector, and efficiency of the solar collector.
- Step 1: open the application,
- Step 2: choose the language (Arabic or English) or exit (close the application),
- Step 3: choose the calculations to do (moisture content or drying characteristics or solar drying characteristics), go back to the home screen, or exit.
- Step 4: write the input parameters then click on buttons to calculate the output parameters, go back to the home screen, or exit.
