The vegetable cleaning machine is made of SUS304 stainless steel with high cleanliness and original color. It is widely used for cleaning leafy vegetables, edible fungi, fruits, seafood and other agricultural and sideline products. It is an advanced equipment in vegetable processing, food, catering and other industries, which meets the national food export standards; Each single machine in the assembly line can be customized according to the different processing characteristics of users to meet the process requirements.
At present, the vegetable cleaning machine 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% - 5% of its initial number. The cleaning method of vegetable cleaning machine is as follows:
1. High pressure spray cleaning
High pressure spray cleaning mainly relies on the force generated by the high-pressure water from the nozzle to remove the dirt on the surface of vegetables.
2. Bubble cleaning
Bubble cleaning method is to make the air into the water, constantly agitate the cleaning water and produce a large number of bubbles. Cavitation occurs on the surface of the object to be cleaned to clean the object.
3. Brush cleaning
The brush type cleaning method is to brush and clean the dirt on the surface of the material through the direct contact between the brush and the material in the water. This kind of cleaning method is suitable for the cleaning of potato, radish and other root vegetables.
4. Roller friction cleaning
The lower part of the roller in friction type cleaning sinks into the water, and the material is put in the screen type roller. Due to the rolling effect of the roller, friction occurs between the material and the material and between the material and the roller, so that the soil on the surface of the material is removed and cleaned. This kind of cleaning has the function of peeling, and the vegetables that can be cleaned have limitations.
5. Ultrasonic cleaning
Ultrasonic cleaning method is to produce millions of tiny vacuum bubbles in the liquid. These bubbles are rapidly generated under the action of sound pressure, and constantly burst violently, resulting in strong pressure and negative pressure suction, which makes the dirt separate from the surface of the object, and will not cause physical damage to the object to be cleaned. The technology of using this method to clean vegetables is not fully mature. Because of the effect of ultrasound, whether it will have a bad effect on vegetable tissue needs to be further studied.
There are many kinds of cleaning machines, which are related to many kinds of vegetables and different material characteristics, and also related to vegetable processing batch and vegetable cleaning requirements.
