SORTING PEARS

Line to Sorting Pears

Rows of pears move along multiple conveyor belts in a modern, brightly lit fruit processing plant, where pear sorting machines and red equipment work efficiently in the background.

Classification and sorting pears

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

Weight - real-time measurement accuracy

In lines equipped with a strain gauge weighing system, electronic sensors with digital filtering and noise reduction measure the weight of each pear in real time, stabilizing readings and facilitating order picking for specific weight classes. This is the heart of a professional sorter in applications where product weight is a key commercial criterion.

Size – precise calibration of diameter and shape

Pears are classified by size based on a series of photos and shape analysis. Vision system algorithms precisely distinguish between sizes, ensuring batch uniformity and consistent packaging appearance.

Color – control of color and blush

Industrial cameras analyze the degree of color and blush. Grading thresholds can be easily adjusted to meet local and export market requirements. The pear sorter maintains consistent color grading even under varying lighting conditions.

Quality – commercial vs. industrial selection

The vision system inspects the surface of each fruit, detecting external defects (e.g., mechanical damage, stains, cracks) and—in advanced configurations—indicating internal defects. This allows for the reliable separation of commercial and industrial pears and the creation of quality subclasses for specific contracts.

Selecting a solution to scale and process

The fault line for large volumes and full automation

CUP Bowl Machine is a modern, universal solution for precise sorting of fresh fruit and vegetables. It gently transports products with a diameter 50–130 mm such as apples, tomatoes, citrus fruits, pears, peaches, apricots.
The line can have from 2 to 6 tracks and reach up to 2.5 t/h per path, and sorting is done in real time according to size, color, weight and quality, which ensures high accuracy and efficiency. The bowl machine can be easily expanded with a water unloading system,unloading operations and devices packaging and palletizing.
Different types of media – standard or oblong bowls – they also handle products with non-standard shapes, such as zucchini, cucumbers, and eggplants. They're the perfect choice for producers looking for an efficient, reliable, and precise sorting system.
