Microwave and convective drying of potato slices

Potato slices were dried using microwave drying combined microwave and convective drying and convective drying Drying conditions included several slice thicknesses power levels and air temperatures The profiles of temperature moisture content and relative humidity as well as shrinkage data were generated Dried products were rehydrated and rehydration kinetics were determined In

Sustainability

In the case for VMD treatment microwave energy was used and thus E t = microwave power drying time (t) while for oven drying thermal energy was considered and thus E t = A v a ρ a c a ∆T t (A = drying container area m 2 v a = air velocity (0 05 m/s) ρ a = air density (1 06 1 045 and 1 029 kg/m 3 at 60 65 and 70

Mathematical modelling of hot air drying of sweet

The drying rate curves consisted of two approximately linear falling rate periods and contained no constant rate period Several mathematical models were fitted to the drying rates of sweet potato slices under a range of drying conditions It was found that the modified Page equation best described the thin‐layer air drying of sweet potato

Ethanol and ultrasound pre

2018-10-1Fresh potato tubers were obtained from a local market (Piracicaba SP Brazil) As shown in Fig 1 the central part of potato tubers was employed to extract cylinders from the perimedullary zone using a sharp stainless-steel tube (diameter of 2 0 cm) Then the potato slices (2 0 cm diameter 0 5 cm thickness) were obtained from the cutting of extracted cylinders
