Color Sorter & Optical Sizer (Weigher
optional)
The tomatoes enter the camera section after being singulated by
flexible diabolic shaped brushes with frequency regulated control of
the direction and rotation speed. To deter these brush rollers from
hardening due to dirt accumulation, cleaning brushes are located below
them.
Color cameras, upon which a picture of the entire tomato becomes
visible, electronically scan the tomatoes. The system can distinguish
32,000 colors.
Color ranges can be selected as required. Basic color, as well as
blush range, are separately adjustable in steps of 1%.. The basic
color can be adjusted by the average color and the blush range by
surface percentages.
The OMS Optical Measuring System with high-resolution cameras scans
the tomatoes in several positions and a computer determines the actual
optical diameter. The size selection can be adjusted in steps of .004"
with an accuracy of .02".
Diameter-length-ratio allows for the separation of long and short
fruits of the same diameter.
If required, the same size tomatoes can be distributed to several
outlets or different sizes to the same outlet.
After leaving the camera section, the tomatoes enter the cups and are
distributed over the selected exits. Unlike other systems, the
tomatoes roll on the exit belts rather than being dropped. This is a
very important feature since dropping is a major cause of bruising,
especially with ripe tomatoes.
The systems are available in 2, 3, 4 and 6-lane versions with an
undersize exit at the end of the lines.
