This paper introduces the existing dry processing technology of fruits and vegetables, such as microwave drying equipment, vacuum freeze drying technology and variable temperature differential pressure expansion technology, and gives an example of joint drying technology. Finally, the development direction of fruit and vegetable drying technology is discussed.
Key words: microwave drying of fruits and vegetables; drying of fruits and vegetables; joint drying
