Optical sizing and colour selection

• Sizing has moved on from historic rising bar systems and weight graders that can be difficult to calibrate accurately when fruit density and shape varies. Both historic systems fail to deliver size grading which is accurate enough for today’s customer requirements.
• Even sizing within a container is vital.
• Optical sizing by camera is the current best practice.
• In many pack-houses colour selection is now carried out by camera. The latest technology will allow colour streaming which enables a more uniform colour presentation within the final pack. This in turn allows an efficient packhouse the opportunity to deliver to the retail customer a top quality pack, and the grower the maximum possible colour grade-out within the specification.
