Classification and sorting plums

We are a Polish manufacturer comprehensive plum sorting lines, designed for precise grading, high efficiency, and gentle fruit handling. Our electronic plum sorting machines can be equipped with tensometric weighing system and advanced vision system, which allows you to sort plums according to parameters such as mass, size, color, coloring and external quality.

Weight - real-time measurement accuracy

In lines with a strain gauge weighing system, electronic sensors with digital filtering and noise reduction measure the weight of each plum in real time. Stable readings facilitate order picking for specific weight classes – crucial where weight is the primary commercial criterion.

Size – precise calibration of diameter and shape

Plum grading is performed based on a series of photos and shape analysis. Vision system algorithms distinguish between calibers, ensuring batch uniformity and consistent fruit appearance.

Color – control of color and blush

Industrial cameras assess the skin's color. Grading thresholds can be easily adjusted to meet the requirements of local and export markets. The plum sorting machine maintains consistent color grading even under varying lighting conditions.

Quality – commercial vs. industrial selection

The vision system inspects the surface of each fruit, detecting typical external defects (abrasions, stem cracks, bruises, spots, bloom defects) and—in advanced configurations—indicators of internal defects. This enables reliable division of plums into commercial and industrial grades and the creation of quality subclasses for specific contracts.

Selecting a solution to scale and process

Mono Line compact single-track

MONO machine is a compact and professional solution designed for small and medium-sized farms. Designed for sorting spherical fruits and vegetables with a diameter of 40 to 100 mm, such as apples, tomatoes, citrus fruits, apricots, peaches.
The device achieves a performance of up to 18,000 pieces per hour and enables precise sorting by size and color. Thanks to the use of a vision system, the machine ensures the highest precision of classification in real time.
MONO machine offers flexibility in the unloading method and ensures smooth and safe transport of fruit without the risk of damage.
The line is equipped with a 6-meter-long buffer channel, a modern dryer with a three-stage filtration system, a V-type conveyor and ergonomic output tables.

• Application: precise sorting based on a vision system, with an emphasis on gentle product flow.

• Unloading: aqueous or dry.

• Advantages: compact size, high repeatability, excellent performance to space ratio.

RDS – Roller Dump Sorting Machine – compact dimensions, impressive performance

RDS is a compact, high-speed sorting machine for spherical fruits and vegetables. The innovative integrated roller system guides the product continuously, without transferring between segments during measurement. This track significantly reduces bruising and allows for a shorter line than in bowl machines with the same number of outputs. RDS It is available in two variants: with water unloading (immersion unloading + water channels + drying) and with dry unloading (tipper + expansion conveyor), which makes it easy to adapt it to the hall and the type of raw material.
