Fruit and vegetable cleaning and sterilizing device and method

Abstract

The invention discloses a fruit and vegetable cleaning and sterilizing device and method. The device comprises a cleaning tank, an ultrasonic signal generator connected with the cleaning tank and transmitting ultrasonic signals into the cleaning tank, an acid water tank, an alkali water tank, a potential water generator and a control unit. A water inlet hole, a jet hole, an overflowing hole and a water outlet hole are formed in the cleaning tank. The acid water tank is communicated with the water inlet hole and the jet hole of the cleaning tank through a corresponding control valve and a corresponding pipeline. The alkali water tank is communicated with the water inlet hole and the jet hole of the cleaning tank through a corresponding control valve and a corresponding pipeline. The potential water generator is connected with the acid water tank and the alkali water tank to provide acid potential water for the acid water tank and provide alkali potential water to the alkali water tank. The control unit is connected with the ultrasonic signal generator, the potential water generator and control valves of the acid water tank and the alkali water tank through lines. By means of the device and method, ultrasonic wave, acid potential water and alkali potential water are organically combined, pesticide residue and dirt on the surfaces of fruit and vegetables can be removed, cleanness is improved, microorganisms attached to the surfaces of the fruit and the vegetables are reduced, and edible safety can be guaranteed.

Description

technical field [0001] The invention relates to the field of fruit and vegetable cleaning, in particular to a fruit and vegetable cleaning and sterilizing device and method for cleaning and sterilizing daily fruit and vegetable products by using ultrasonic waves and oxidation potential water. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for nature, nutrition and health. Fresh fruits and vegetables are rich in various vitamins and minerals, and contain various antioxidant and anti-aging ingredients, so they are favored by consumers. However, with the increase in the consumption of fresh fruits and vegetables, the cases of foodborne diseases caused by fruits and vegetables are gradually increasing, and the importance of killing pathogenic microorganisms on the surface of fruits and vegetables has gradually become prominent. [0003] For specialized food processing enterprises, a large number of fruit and ve...

AI Technical Summary

Problems solved by technology

[0003] For specialized food processing enterprises, a large number of fruit and vegetable products need to be cleaned and sterilized before they are packaged as finished products for consumers to eat directly. , but also to remove residual pesticides and other chemical substances as much as possible. Conventional cleaning methods rely on water soaking and cleaning or special fruit and vegetable cleaning agents, and fruit and vegetable cleaning agents are also produced by chemical methods. Therefore, in order to avoid residues, it is necessary to rinse with a lot of water. Not to mention the limited cleaning effect, it also brings a lot of waste of water resources, and it is difficult to realize the automation of operation
