Strategy for longan drying in two-stage superheated steam and hot air
The aim of this research was to investigate a novel strategy and to develop a model for longan without stone drying using a two-stage SSD + HAD process (superheated-steam drying followed by hot air drying). The experiments were conducted using superheated-steam at: 120, 140, 160, and 180 °C followed...
