The nutritional value of fruits is extremely high. To ensure high accuracy in the process of sorting, and to protect the fruit powder of the fruit skin is a major problem in sorting. The appearance of the fruit selection machine has been in existence for many years. Select fruit to use professional fruit sorting equipment, that is, fruit selection machine, blueberry sorter, only the use of a professional fruit selection machine can not hurt the fruit powder in the separation process.

Automatic fruit selection machine assists fruit growers to achieve sub-grade sales. The sorting machine uses physical vibration to classify different sizes of blueberries and sorts them from small to large. The sorting efficiency can reach 1.5-2 tons per hour, and the sorting process does not harm the fruit powder. For example, sorting fruits. First, the leaky hole with a small diameter is leaked, and the large diameter moves forward with the belt to the second level, which is suitable for the size of the exposed eye and then leaks to the second level of the lower fruit area, and so on. The largest is the fourth level below the 3rd level. Can be placed in the fruit area electronic weighing instrument for weighing and packing, saving labor. Fruit sorting can add the necessary links to integrate a complete fruit sorting and packaging line.

A survey of the use of automatic machine selection in the country Recently, the author visited the Xinda Pear professional cooperative in Tiantai County and saw that on one of the two transmission belts, only one Cuiguan pear was transported to different baskets according to size, and was then loaded into boxes by workers. This is one of the two automatic fruit splitters introduced by Tiantai Haifeng Pear Cooperative.

After automatic fruit splitting machine, Pear was divided into four grades of 300 grams or more, 250 grams to 300 grams, 200 grams to 250 grams, and 200 grams or less. The Haifeng Pear Cooperative sells pears ranging from 12.5 tons to 15 tons per day, and the automatic fruit sorter can sort 7 tons per hour. One day's shipment can be completed in two hours.

“Compared with previous experience, employees selected fruit based on experience and feelings, and the fruit machine was selected more accurately, and it was also recognized by customers. What kind of pears customers buy is what they buy. They are also confident about their acquisition.” Wang Jianzhong said that this change in sales methods. It also boosted the price of honey pears.

A pear pear fruit selection machine and honey pear sorting machine can save about 50 workers for honey pear sorting, and for pear pears to select fruit for diameter sorting, it is lighter than hand holding. Through the transmission belt with low height, the pears that have been sorted out are transmitted, and the anthocyanins of honey pears are protected from damage and extend the shelf life of honey pears.

Domestic Fruit and Vegetable Storage and Transportation Fresh-keeping Equipment Application Overview The current domestic production of fruit grading equipment is basically limited to the mechanical grading stage, which mainly involves grading the size and weight. At present, the 6GF-1.0 fruit sizer and classifier developed in China adopts the advanced principle of roller and belt gap grading. When working, the graded roller rotates at a constant speed and the conveyor belt moves in a straight line. When the diameter of the fruit is smaller than the gap between the grade roller and the conveyor belt. At that time, the gap is dropped into the fruit slot.

China's domestic automatic grading equipment is still basically in the laboratory stage. The fruit quality automatic detection production line used in the fruit quality inspection in China is mostly imported equipment. This imported equipment is designed for large farm production and is not practical in the detection of small farmer products in China.

Since domestic research on fruit quality testing and automatic grading has not been long, there have been some successful studies, but it is far from being widely used. Therefore, there are still many problems that need to be resolved. For example, the objects of domestic research are mostly carried out under static conditions. In addition, the previous research on fruits was mainly on the grading of single-channel single indicators. When testing on multiple quality indicators of fruits, the processing speed was slow.

The rapid and complete detection of fruit quality, simultaneous multi-channels, and one of the difficulties that domestic scholars need to continue to study and overcome. At the same time, there is still a great deal of distance between theory and practice. At present, the grading equipment used in our country's fruit is still limited to the mechanical grading method, that is, the use of weight and size grading equipment for grading; machine automatic grading equipment mainly depends on imports, applications are not widely used. Therefore, we need to track the latest developments in the world and make full use of the research results that have been achieved abroad, explore new theories and methods, and vigorously develop new types of automatic grading hardware devices, which will greatly increase the speed of processing. At the same time, efforts should be made to apply new technologies to actual production. This has important theoretical and practical implications for the improvement of the quality of China's domestic fruits, the ability to participate in international competition, and the reduction of labor intensity of workers. The economic and social benefits.
