High Precision Kiwi Fruit Sorting Machine With Rolling Bar

This roller-type kiwifruit sorter primarily relies on a three-step mechanism: fruit rolling + gap screening + diverted discharge. Its core process is as follows:

Feeding & Fruit Loading
Kiwifruit enter the sorting area at the top of the machine via a conveyor belt or elevator, typically arranged in single or multiple rows, ensuring even distribution of the fruit onto the rollers.

Roller Drive & Fruit Rotation
The machine utilizes a series of parallel rollers (rolling bars) that can rotate synchronously or asynchronously. The fruit rests on the rollers, slowly turning and rolling as the rollers rotate. As the fruit rolls, its surface gradually faces upward, facilitating inspection and evaluation. This is similar to the "rolling bars continuously rotating the fruit" mechanism used in roller sorters.

Gap Screening / Position Rejection
The spacing between the rollers is divided into several levels. Fruits with a diameter or smaller shaft diameter that is smaller than a certain gap are "dropped" to the lower channel for sorting. Larger fruits move on to the next roller stage. This differential gap design enables grading by diameter/size.

Discharge/Diversion Guidance
The sorted fruit is guided to the discharge outlets of different grades via guide troughs, gravity chutes, or conveyor belts. Fruit of different grades then enter separate collection bins or downstream processing stages.

Manual/Visual Supplementary Inspection
Some machine designs feature observation channels on both sides, allowing manual or visual inspection to identify fruit with obvious defects. Some versions can also be equipped with vision sensors or camera recognition systems to assist in rejecting unqualified fruit.

The entire process is an automated grading process that combines mechanical, gravity, and axis gap control. The equipment is typically constructed of food-grade stainless steel, features adjustable axis spacing and roller speed, and a modular design to accommodate various kiwifruit sizes.

Adjustable Roller Spacing Design
The spacing between rollers of different grades is adjustable to accommodate kiwifruit of varying diameters and sizes.

Parallel Rollers + Asynchronous/Synchronous Drive
The rollers can be configured in multiple sections, allowing them to operate at varying speeds or directions to optimize fruit turning and sifting.

Food-Grade Stainless Steel + Corrosion-Resistant and Rust-Resistant Construction
Fruit-contacting parts and the machine frame are constructed of SUS304/SUS316, resulting in a smooth surface with no blind spots, making it easy to clean and disinfect.

تصميم وحدات + Expandable Interfaces
The modular structure of the equipment facilitates maintenance and replacement, and includes upgrade options for visual inspection, reject air blowers, and data interfaces.

High Precision and Consistency
Roller rotation ensures equal inspection of the fruit from all directions, resulting in higher grading accuracy than single-axis diameter measurement or manual inspection.

Low Fruit Damage
The rollers move gently, eliminating vibration and impact, reducing the risk of bruising and breakage of the kiwifruit skin.

الأتمتة / High Efficiency
Continuous feeding and roller grading reduce manual intervention, increasing sorting speed and capacity.

Flexible Compatibility with Different Sizes
Adjustable wheelbase and variable speed drive adapt to grading needs of kiwifruit of varying sizes and varieties.

Improve product grading standards and market competitiveness
More refined grading and consistent specifications make packaging and export more compelling, increasing product added value.

Save labor and reduce error costs
Automated grading replaces manual visual inspection and sorting, reducing labor costs and error rates.

Shorten grading steps and accelerate processing
Increased grading speed streamlines the kiwifruit process from sorting to packaging and cold chain transportation.

Reduce losses and increase yields
Low damage and high grading accuracy reduce the proportion of defective fruit and mixed grades, increasing the overall yield of good products.

Roller sorting systems are widely used in fruit grading equipment for sorting spherical/oval fruits such as apples, oranges, and kiwis.

"Roller-type fruit and vegetable graders" are listed as standard grading solutions, particularly suitable for diameter/size sorting.

Some technical descriptions cite the roller sorting design's ability to "continuously rotate the fruit, exposing the outer surface," as a way to remove defective fruit.

باختصار, the High Precision Kiwi Fruit Sorting Machine with Rolling Bar is a high-end grading machine tailored to the characteristics of kiwifruit, combining precision and gentleness. Based on the principle of roller drive and inter-axial screening, it automatically rotates, sorts, and removes the fruit while in motion. Compared to traditional manual or simple diameter measurement methods, it offers significant advantages in grading accuracy, كفاءة, fruit protection, and automation. For kiwifruit processing plants, fruit and vegetable exporters, or packaging companies, this machine can significantly improve product standardization, تناسق, and shipping quality.
