Method and equipment for washing, disinfecting, sterilizing, preserving and processing fruits and vegetables with leaves

Abstract

The invention discloses a method and equipment for washing, disinfecting, sterilizing, preserving and processing fruits and vegetables with leaves. The method for washing, disinfecting, sterilizing, preserving and processing the fruits and vegetables with the leaves comprises the following steps: primarily selecting on line, automatically washing by ultrasonic waves, spraying and cleaning, drying and sterilizing, waxing and polishing, sterilizing, sorting and packaging. The preserving and processing method utilizes the ultrasonic waves to wash the fruits and vegetables with the leaves so as to reduce the damages to the fruits and vegetables with the leaves in the washing process; nano-grade natural pure lac wax is used as a raw material and is atomized by externally-arranged pneumatic high pressure through a motor-driven waxing device; under the effect of a precision metering pump, the fruits and vegetables with the leaves continually roll on a flexile hairbrush so that the peels of the fruits and vegetables with the leaves are uniformly coated with the fruit wax; the fruits and vegetables with the leaves are sterilized and disinfected before the waxed and polished fruits and vegetables with the leaves are packaged by grades, so as to further improve the food safety of the fruits and vegetables with the leaves.
