Multi-objective optimization determinate the optimized drying parameters for commerson anchovy by infrared assisted heat pump dryer

Abstract

This paper presents the results of experimental research to determine the optimal drying parameters of Stolephorus commersonnii by heat pump drying method combined with infrared radiation. The experiment was designed according to Taguchi's method with drying parameters including drying temperature (t), drying agent velocity (V), infrared radiation distance (H). As a result of multi-objective optimization by RSM response surface method, optimal drying parameters were obtained for good quality dried Stolephorus commersonnii, short drying time and energy saving. Specifically, the optimal drying parameters for dried Stolephorus commersonii are determined as follows t = 47,35 oC, V = 1,73 m/s, H = 30 cm, IP = 1000 W, relative humidity of the air drying φ = 15 ÷ 17%, drying time τdying = 126 minutes.
