In this study, briquettes dried under ambient conditions were harder than those dried at 70 °C (oven) only or first dried at 70 °C and then under ambient conditions (P b 0.01). The rate of moisture loss was greater for samples dried in the oven (moisture was 20% after 2 days of drying) than for those dried under ambient conditions (moisture was 20% after 7 days of drying). These results suggest that a faster rate of moisture loss may reduce the ability of the particles to bind effectively
during drying (Kaliyan and Morey, 2009). Briquettes were produced
