How to Choose a Fruit and Vegetable Sorting Machine? Principles and Maintenance Points Explained

Growers who plant fruit trees all know that harvesting the fruit is only the first step, and the sorting and grading that follows is the real "hard labor." In the past, people relied on their eyes and hands, and a family sorting several tons of fruit would be busy for days, and it was easy to mix sizes together and fail to get a good price. The fruit sorting machine was created to solve this problem. It can automatically grade fruit according to indicators such as size and weight, getting the work done quickly and evenly. Below, let's talk about the principles, purchasing, and daily use of this type of equipment.

How the fruit sorting machine works

Common fruit sorting machines are mainly divided into two types. One type sorts by size, mostly using a roller-type or roller-belt structure. The fruit moves forward on rolling rollers, and the gaps between the rollers gradually become larger, so small fruit falls through first, while large fruit travels farther, and the grades are naturally separated in this way. The other type sorts by weight, using a weighing device to weigh each fruit and automatically tipping the tray or discharging the material when the set weight is reached. It has higher precision and is suitable for citrus, apples, pears, and other fruits priced by size and weight. Some models also add visual recognition functions, which can incidentally remove fruit with bruises or deformities, improving the sorting effect.

Focus on these points when purchasing

First, look at the suitable crop. Different fruits differ greatly in shape, peel thickness, and tenderness. For example, kiwifruit is easily bruised, and peaches are easily pressed. When purchasing, confirm that the materials of the parts in contact with the fruit are soft, and that conveying is stable. It is best to test the machine first with your own fruit. Second, check whether the processing capacity and grading levels match your own output. Cooperatives and purchasing stations use large quantities, so they should choose models with greater processing capacity. Third, look at the materials and workmanship. The parts in contact with food should meet relevant hygiene requirements, and equipment with a sturdy frame and smooth welds is more durable. Fourth, look at after-sales service. Whether spare parts are easy to buy and whether the manufacturer can come to repair promptly directly affects whether normal operations can start during peak season. In addition, many regions have already included primary processing machinery for fruits and vegetables in the scope of agricultural machinery purchase subsidies. The specific subsidy catalog and amounts shall be based on information published by the local agricultural machinery authorities.

Key points for daily use and maintenance

Before starting the machine, let it run idle for a few minutes, listen for any abnormal noise, and check whether debris is stuck on the conveyor belt or rollers. Before sorting, it is best to clear leaves and branches from the fruit pile to avoid machine jams or damage to the equipment. After the work is finished, promptly clean fruit stains and residual leaves to prevent mold and spoilage from contaminating the next batch of fruit. Regularly add lubricating oil to rotating parts such as bearings and chains, and check whether weighing components and electrical wiring are affected by moisture. During long-term shutdown, take measures against dust and moisture, and do a full inspection again before starting work the following year.

Overall, the fruit sorting machine hands over the most labor-intensive sorting step to a machine. It not only saves labor, but grading is also more consistent, and the fruit can sell for a better price. When purchasing, make a rational decision based on your own varieties, output, and budget. Use it well and maintain it well, and the harvest season will save you a lot of worry.
