Method for preparing bean snack crisp grains by means of a combination of medium and short wave infrared vacuum drying and negative pressure microwave pulse spouting drying.

摘要

A method for preparing bean snack crisp grains by means of a combination of medium and short wave infrared vacuum drying and negative pressure microwave pulse spouting drying relates to the field of fruit and vegetable food processing technologies. In the present invention, pretreatment, that is, cleaning, color protection, blanching or steaming and stewing, and draining, is first performed on beans, then a combination of medium and short wave infrared vacuum drying and negative pressure microwave pulse spouting drying is performed, and finally, obtained bean snack crisp grains are packed. In the present invention, a combined drying manner of medium and short wave infrared vacuum drying and negative pressure microwave pulse spouting drying can shorten a drying time, lower power consumption for the drying, and improve evenness of the drying and is a drying manner with a bright future.
