Description:

Optimum Sorting Concept Engineers optical grading machine for defect grading on carrots.
Complete with length / chunk grader

This machine is used to sort defect on carrots. But it can also be used to sort other products.

The model Focus from Concept Engineers is an optical sorter especially developed to sort products with various optical deficiencies. Discoloration, deformation and foreign objects are detected and accuratelyremoved from the product flow. The Focus can be used for fresh / dried or frozen potato product, vegetables, fruit as well as seafood. Use of the Focus will lead to quality improvement of your final product, but also to lower and more predictable production costs.

Capacity

The capacity is maximum 15,000 kg of carrots per hour on the machine (good and bad), depending on the size of the carrots with a defect level of up to 30 % failure.

Principle of operation

The carrots are fed to the conveyor via an input vibrating screen. This distributes the product evenly (in width and length direction), while this vibrating screen can be used at the same time as a fracture / length sorter.
The product comes through a chute on the white inspecion belt of the grading machine. The purpose of this chute is to feed the carrots in the correct speed to the sorting machine. Because of this the product will remain still on the inspection belt.
The Concept Engineers belt sorter is equipped with two B / W CCD line scan cameras and features both color and shape recognition.

Simple to operate

Through a color touch screen this machine is very simple to operate. The set values are stored in a sorting program.
Special software developed for sorting carrots. To check the grading results, the machine is equipped with a static program (pie chart), which controls the number of graded carrots at various set-ups.
The following points distinguish the optical sorting of Concept Engineers from its competitors:

• Easy to install by only connecting electrics, air and water.
• Cleaning friendly by using lots of sheet material and minimize horizontal surfaces where product can accumulate on.
• Use of many on the market available componets, such as belt, bearings, motor, lamps and other electrical items.
• Quickly and easily replaceable parts, such as lights, cameras, belt and motor.
• Industrial computer composed of a high-speed processor for control of the machine. And a local processor system for the cameras and processing the camera signals.
• Touch screen control panel with 'frame grab' feature and many control options. However, simple to operate for the operating staff.
• The minimum response time of the discharge valves is 2 milliseconds.
