Document Type and Number:
Japanese Patent JP2019045133
Kind Code:
A
Abstract:
To provide a combined drying method of firstly microwave vacuum drying and high-temperature high-humidity drying, wherein: the drying time can be shortened, and energy consumption can be reduced; the rice staple food has short rehydration time and high rehydration capability; and the excellent sensing quality can be kept.SOLUTION: A method for drying an instant rice staple food comprises the following steps: (1) manufacturing rice into a rice staple food; (2) performing microwave vacuum drying on the rice staple food at a vacuum degree of 0-0.08 MPa and power of 600-2,000 W, until the moisture content of the rice staple food is 40-50 wt.%; (3) drying the rice staple food at high temperature of 70-110°C and high relative humidity of 40-65°C, until the moisture content of the material is 15-20 wt.%; and (4) reducing temperature and humidity of the staple food, drying at a temperature of 30-40°C and relative humidity of 20-30°C until the moisture content of the material is 7.5-12.5 wt.%.SELECTED DRAWING: None
