Raynbow Optical Sorting Machine offer an efficient and versatile solution for sorting various products using advanced optical technology. Equipped with high-resolution sensors, the machine employs a cutting-edge "high-speed double vision" system to meticulously analyze 100% of the surface of each item.

Primarily designed for agro-food products such as fruits and vegetables, Raynbow excels in identifying and eliminating color defects, blemished produce, and foreign objects that may share the same color as the desired product. To ensure comprehensive inspection, the products are carefully placed on a conveyor belt, which prevents them from rolling off. This setup enables thorough examination of all items, and if necessary, they can be promptly ejected when they meet predetermined criteria in both the vision zone and the reject zone.

Raynbow offers a flexible rejection system that can be tailored to specific needs. It can feature either an electro-pneumatic or air activation palette reject system, utilizing electrically controlled ejection valves. Additionally, it can be configured with a single ejection system or operate in 3Way mode, which incorporates two reject systems to distinguish between unusable produce and defects classified as second choice.

TECHNOLOGY:

RAYNBOW is a hexa-chromatic machine equipped with NIR (Near InfraRed) technology for Visible Color analysis
NIR technology can detect the presence of rot and foreign bodies (even if completely black)
Visible Color analysis allows colour defects to be detected, such as green products, yellowing, etc. In optional mode, the machine can conduct chlorophyll analysis to allow very accurate detection of foreign bodies in products with high chlorophyll content (apples, green beans)
An ethernet connection is available for remote control
The machine detects statistical data on rejected products for quality analysis of the selected raw material

Raynbow can have a palette reject system

APPLICATIONS:
Tomatoes, Cherry tomatoes, Potatoes (unpeeled and peeled), Carrots, Green beans, Onions (unpeeled and peeled), Peppers (whole and cored), Artichokes, Olives, Peaches, Apricots, Cherries, Oranges, Apples, Walnuts (with shells), Strawberries, Pears

BENEFITS:

High production capacity. Enables selection of large quantities of product in little time
Significant labour savings (up to 100% according to application)
Detection in real time of qualitative and quantitative data of raw material analysed
Automatic capture of images of rejected products and their filing for post-production analysis
Constant selection over time, also over 3 work shifts
Low maintenance costs
User-friendly for easy use and programming
