This paper aims to study the influence of temperature and relative humidity (RH) during intermittent heat pump drying at 28.6-40.6 degrees C, 16.2-26.7% RH, a = 0.2-1.0, and the comparison was made against fan drying (27 degrees C, 39.7% RH, a = 1.00). It was observed that the effects of temperature and RH on drying rate were significant when moisture content was high. Experimental results showed that intermittent heat pump drying at 28.6 degrees C, 26.7% RH, a = 0.2 of edible bird's nest greatly reduced effective drying time by 84.2% and color change compared to fan drying, and retained the good energy efficiency.
