In fruit processing, product quality, uniformity and processing speed are critical. At the same time, fruit is a natural product with strong variation in ripeness, colour, shape and texture. That makes accurate sorting and grading complex – especially at high volumes and with fragile products where every fruit counts for overall food processing efficiency.
The OptiServe optical sorting machine for fruit products is not a standard colour sorter, but an intelligent machine vision and product classification system that analyses multiple product characteristics at the same time. This allows the inspection system to detect even subtle quality differences, deliver consistent grading and sort reliably.
The result: higher product quality, stronger quality control, less waste and maximum value from every batch of fruit.
OptiServe has developed this optical sorter for companies in food processing that work with fruit on an industrial scale, such as:
Fruit processors face complex quality control challenges every day that directly impact yield, customer satisfaction and food safety.
fruit varies significantly in colour, ripeness, shape, size, texture and structure. Simple colour sorting is not enough to guarantee consistent grading and product quality.
many deviations are hard to detect visually, such as bruising, damage, rotten spots and discoloration. Without accurate defect detection and product inspection, this leads to quality loss or unnecessary reject.
fruit streams can contain unwanted elements such as leaves, twigs, stems, stones or plastic. Reliable foreign material detection and contamination detection is essential for food safety.
fruit processors operate under pressure from high volumes, fragile products and strict quality standards. This calls for an inspection system that combines speed, productivity and extreme accuracy.
The OptiServe optical sorting and grading machine is designed for a broad range of fruits and food processing applications, including:
Because fruit shows natural variation, the system analyses products on multiple characteristics at once through multi-dimensional object recognition and advanced machine vision. Detection is based on colour, shape, length and structure. Through this combined analysis, the inspection system can accurately identify bruising, detect ripeness differences, distinguish real defects from natural variation and minimise false reject. This makes our optical sorting and grading significantly more effective than traditional sorting methods.
With belt speeds of up to 5.2 m/s, our optical sorting machine is built for industrial fruit processing. This delivers major benefits for fruit processors: processing of large volumes per hour, support for continuous production, higher productivity and no bottleneck in the processing line. Even at high speed, sorting accuracy and grading quality remain consistently high.
The system uses targeted air pulses to remove individual off-spec products. Benefits include highly accurate ejection of damaged fruit with minimal impact on good fruit. The result: less product loss and better protected product quality. This is essential for fragile products such as berries and cut fruit.
Sustainability and efficient energy use are increasingly important factors in modern fruit processing. Our system delivers up to 50% lower compressed air consumption, reduced operational costs, a more sustainable production process and a smaller environmental footprint. This means sorting is not only more accurate, but also more energy-efficient – supporting both productivity and sustainability targets.
Every fruit stream calls for a different sorting strategy. Our system therefore supports multiple configurations for different quality streams and grading classes: 2-way sorting (good product / reject), 3-way sorting (flexible settings: premium quality / standard quality / reject) and reverse sorting (separating good products from the reject stream). This makes it possible to create multiple grading classes and to split premium and standard fruit streams.
Alongside sorting, our system collects valuable production data – the number of sorted fruits, defect rate, shape and size distribution, and quality variation per batch. This data supports continuous process optimization, strengthens quality control and fits naturally into industrial automation environments. Sorting becomes a core source of insight for improving manufacturing efficiency.
Through intelligent product classification, high processing speed and precise ejection, our optical sorting and grading technology helps fruit processors to:
In this way, optical sorting becomes a strategic part of an efficient, sustainable and future-proof fruit processing operation.
