Now we buy a lot of fruit from the market are through manual sorting. Manual sorting is suitable for various varieties of fruit, and it is the most widely used method of fruit grading in China. Artificial sorting is to judge the size, shape and color of fruit according to human subjective vision. There are also semi mechanical classification methods such as fruit selection plate, sieve, rotary belt and roller. The advantage of manual sorting is to minimize the mechanical damage to fruits in the grading process. The disadvantage is that human subjective judgment is greatly affected by personal vision, color recognition ability, external light and other factors, so it is difficult to classify fruits in strict accordance with the grading standards, and the labor intensity is high, which requires a lot of labor.

With the continuous improvement of consumers' requirements for the quality of fruits, it is imperative to carry out strict quality classification in order to improve the commercial value of fruits and realize the mechanization and automation of fruit sorting.

First industry customers reported that the fruit sorter has brought them great economic value. The fruit sizing machine sorts the fruit according to weight or size, and the anti-collision device effectively prevents the damage to the fruit in the sorting process. It is not only convenient to price according to the quality, improve the commodity quality of fruit, improve the economic efficiency of production, but also meet the different needs of different customers, and the effect is satisfactory.
