The fruit and vegetable grading machine is a mechanical device mainly used for sorting and grading fruits and vegetables based on their size, weight, and other characteristics.

Fruit and vegetable grading machines are mainly divided into two types:

Fruit and vegetable roller grading machines and fruit and vegetable vibration grading machines are commonly used in fruit and vegetable processing production lines.

1. Fruit and vegetable roller grading machine:

The fruit and vegetable roller grading machine moves fruits or vegetables forward by rotating rollers. Smaller fruits or vegetables drop onto the next roller until sorted into the corresponding grade.

This machine is suitable for different sizes of fruits and vegetables, such as apples, pears, persimmons, tomatoes, etc. It is usually used in classifying, grading, and packaging fruits and vegetables in processing production lines.

2. Fruit and vegetable vibration grading machine:

The fruit and vegetable vibration grading machine uses the vibration principle to sort and grade fruits or vegetables.

In this machine, fruits or vegetables move on a specially designed conveyor belt, and vibrators with different amplitudes and frequencies classify and grade them.

This type of machine is suitable for irregularly shaped, fragile, and sensitive fruits and vegetables, such as strawberries, grapes, peppers, etc. It is usually used for quality inspection of fruits and vegetables in food processing factories or packaging before the sale.

Overall, both types of vegetable grading machines can improve fruit and vegetable grading efficiency and accuracy, increase production efficiency, and reduce labor costs.
