Drying kinetics of packed bed and microwave drying of enriched couscous

What is it about?

Drying kinetics and modeling of enriched couscous with two different compositions (A and B) were carried out by using packed bed (60 and 80 °C) and microwave (180 and 360 W) drying techniques. Seven drying models were used to determine the best fitting of experimental data.

Why is it important?

Couscous production should be developed especially for drying step. Couscous particles are fragile and porous, and they can be broken during drying. Traditionally, couscous is dried under the sun, which is not technological and hygienic drying technique because it is open to environmental contamination.
