Birth of the fruit classifier

Birth of the fruit classifier

In the same fruit, there will always be different sizes, large and small, and the price of many fruits will be differentiated by size. For example, the price of large cherries and small cherries is far from the same. In the early stage of fruit business in the market, the classification of fruit is mainly in the natural way, that is, between farmers and vendors, using hand-measuring methods, such as the classification of Sichuan Jiangjin sweet orange is based on the size of the palm, etc. For the first class, that is, one hand holds the fruit, the other palm is covered with the gap; the second is called the four fingers; the third is called the three fingers; the fourth is called the two fingers; the fifth is called the one finger; Not pointing. The grading of peaches in Ningbo, Hangzhou and other places is based on the steamer basket: two rounds of one point; two rounds of two; two rounds of three; three rounds of one; three rounds of two... until four rounds are filled The cage is the worst. At present, the size of the fruit path is measured by the same size plate, and the apple and pear-based classification and packaging inspection draft are published. The specification of the fruit grade includes the weight and color in addition to the individual size. Specific provisions for the degree of injury at the beginning.

Nowadays, the age of relying on the naked eye and manual operation to distinguish the size of the fruit has passed, because the efficiency is far behind the demand, so a fruit classifier is born.

Fruit graders need to customize the machine according to the size of the processed fruit. For example, some machines are suitable for processing fruits such as apples and oranges, while others are suitable for processing such as strawberries and cherry fruits.
