The effects of microwave power density (_= 3.31, 4.43, 5.59 W/g) and intermittent ratio (PR= 1, 2, 3) on the drying characteristics and quality of broiler wing roots were studied. The results showed that the microwave drying equipment of broiler wing roots was mainly a constant drying process, and the changes of moisture content and drying rate were significantly affected by microwave treatment conditions (P<0.05).
By comparing and analyzing the regression statistical results of eight drying empirical models, it was determined that Page equation was the best drying model (average R2 = 0.9958, average 2 = 0.0003), which could accurately predict the moisture content of broiler wing roots during microwave intermittent drying (PR = 1, 2, 3).
