Vegetable washing machine is a specialized machine for cleaning fruits and vegetables, which can be divided into two categories: commercial vegetable washing machine and household vegetable washing machine. The working principles of commercial vegetable washing machines mainly include ozone and ultrasonic principles; There are three main working principles of household vegetable washing machines: ozone, ultrasound, and micro electrolysis of water, also known as plasma technology.
Vegetable cleaning is one of the essential processes in vegetable processing and clean vegetable production. In 2013, vegetable cleaning mainly relied on manual labor, with a low degree of mechanization; There are two types of vegetable cleaning machines available: vibration spray and drum. The vibrating spray vegetable cleaning machine has two cleaning tanks. Vegetables first move back and forth in the vibrating cleaning tank for preliminary cleaning, and then enter the spraying tank to spray with clean water, completing the entire cleaning process. This cleaning machine consumes a large amount of water and causes significant damage to leafy vegetables.
The main body of the drum type cleaning machine is a tilted metal mesh cylindrical rotating body, and there are many spray pipes with nozzles installed at the central axis of the cylinder. Vegetables are constantly rotated with the cylinder while being washed away by the spray water flow, achieving the purpose of cleaning. This cleaning machine can only clean root vegetables such as potatoes and sweet potatoes, and it can cause significant damage to the vegetables during cleaning. Therefore, it cannot be used for cleaning leafy vegetables.
Whether it is a vibrating spray or a drum type, commercial vegetable washing machines mainly aim to clean the dirt and debris on the surface of fruits and vegetables.
