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.

Description

technical field [0001] The invention belongs to the field of fresh-keeping processing of leafy fruits and vegetables, and in particular relates to a method and equipment for cleaning, disinfecting, sterilizing and fresh-keeping processing of leafy fruits and vegetables. Background technique [0002] The commercial processing and treatment of citrus and other fruits and vegetables is already a relatively mature industry. With the development of social economy and the improvement of people's living standards, the consumption demand for citrus and other fruits and vegetables has become higher. At present, the domestic sales market has Most markets require citrus and other fruits and vegetables to be sold with their leaves washed, disinfected, sterilized and kept fresh to reflect the freshness of citrus and other fruits and vegetables, otherwise it will be difficult to be recognized by consumers, which brings new problems to the processing of citrus and other fruits and vegetable...

AI Technical Summary

Problems solved by technology

[0004] 1. Fresh leafy fruits and vegetables are not soaked and cleaned thoroughly in the cleaning tank with liquid medicine, so the preservation effect cannot be achieved. More importantly, the leafy fruits and vegetables will be damaged during the repeated cleaning process and affect the freshness preservation effect. In addition, the cleaning tank The sludge in the tank cannot be isolated and discharged, resulting in the growth of bacteria and thus failing to achieve the real effect of cleaning;

[0005] 2. The waxing driven by the motor will cause the fruit wax to be sprayed unevenly on the surface of the leafy fruits and vegetables, and the waxed leafy fruits and vegetables have not been sterilized, so the uniformity of waxing of the leafy fruits and vegetables cannot be guaranteed. No fresh-keeping effect;

[0006] 3. The waxed and polished leafy fruits and vegetables lack a disinfection process before entering the grading packaging, which needs to be improved for food safety. In addition, manual grading is labor-intensive and time-consuming, and the efficiency is low, which cannot meet the needs of customers.
