Vegetables are good for the body and are called green foods. However, with the development of pesticides in recent years, many people have used pesticides to prevent pests. Pesticides can affect health. This is how vegetable washing lines have appeared. Today, let’s talk about bubbles. Vegetable washing line.

 　　 Vegetable washing line is used as a variety of food processing ingredients and processed for clean vegetable disposal. Before processing, the vegetables must be cleaned and disposed of. Vegetables are used as ingredients in food processing (clean vegetable processing). There are many types of vegetables. When cleaning, they will stop sorting and cleaning according to different types of products. To ensure that the vegetable washing line cleans the vegetables. In order to ensure that the vegetables are cleaned, high-pressure spray equipment is added to the upper end of the cleaning pool of the vegetable washing line when the vegetables with lighter specific gravity are cleaned, and the vegetables floating on the water surface are hit by the high pressure of the vegetable washing line by the high pressure water generated. Put the water into the water and stop washing repeatedly to ensure that the vegetables are clean. For the cleaning and disposal of leafy vegetables, we choose the cleaning method of the bubble-type vegetable washing line. Using vegetable bubbles to gently clean the vegetables will not damage the vegetables. It is important to ensure the integrity of the vegetables.

 　　 There are several cleaning methods in the vegetable washing line. At present, the vegetable washing line mainly uses high-pressure spray cleaning, bubble cleaning, roller friction cleaning, brush cleaning, ultrasonic cleaning and other methods. Through the correct cleaning method, the number of microorganisms will be reduced to about 2.5% to 5% of its initial number. The cleaning method of the vegetable washing line is explained as follows:

 　　1, high pressure spray cleaning

 　　 high-pressure spray cleaning mainly relies on the force generated by the high-pressure water sprayed from the nozzle to remove the dirt attached to the surface of the vegetables.

 　　2, bubble cleaning

 　　Bubble cleaning method is to let air into the water, constantly agitate the cleaning water and produce a lot of bubbles, cavitation occurs on the surface of the cleaned object, so that the cleaned object is cleaned.

 　　3, brush cleaning

 　　Brush cleaning method is to brush off and clean the dirt on the surface of the material through the direct contact of the bristles with the materials in the water. This type of cleaning method is suitable for cleaning root vegetables such as potatoes and radishes.

 　　4, drum friction cleaning

 The lower part of the drum cleaned by the drum friction vegetable washing line sinks in water, and the material is placed in the screen drum. Due to the rolling action of the drum, friction occurs between the material and the material and between the material and the drum, so that the surface of the material is removed and the soil is removed. Clean, this type of cleaning also has the effect of peeling, and the vegetables that can be washed have limitations.

 　　5, ultrasonic cleaning

 The ultrasonic cleaning method is to generate millions of tiny vacuum bubbles in the liquid. These bubbles are rapidly produced in large quantities under the action of sound pressure, and continuously blasted violently, generating strong pressure and negative pressure suction, so that the dirt is separated from the object. The surface of the cleaned object will not cause physical damage. This method is used to clean vegetables, the technology is not yet fully mature, due to the effect of ultrasound, whether it will have an adverse effect on vegetable tissues needs further study.
