As shown in Fig. 2(b), the moisture content decreased faster with
the increase in the frying temperature (at a fixed power density) in
MVF and the moisture content reached as low as 1.58 g/100 g in
6 min at 120 C. It also can be seen in the Fig. 2(c) that the rate of
dehydrate in MVF is faster with the higher vacuum degree and the
rate of dehydrate got the fastest with the 0.085 MPa
