[0002] An apple screening machine is a device used for screening and grading apples. It can automatically separate apples into different grades according to their size, weight, and other characteristics. Common types include balance weight sorting machines and screening devices that sort apples by weight.

[0003] A multi-size apple screening machine is a device designed specifically for multi-dimensional size screening of apples. It typically uses mechanical transmission to drive the screen to vibrate, or uses rollers, belts, and other devices to separate apples into multiple grades by size through different-sized screen holes or gaps. It is highly efficient, precise, and highly automated, and can meet the diverse size requirements of different markets.

[0004] The existing multi-size apple screening machine still has the following problems: when the apples are screened and discharged, they are prone to bruising, and it is not easy to clean the juice.
