Many Nuts, One Sorter

Sorting through millions of nuts would be an impossible task for human workers. The quality of the output would also be very inconsistent since humans are prone to error. By using an SG nut color sorter, you can avoid those problems and get a high-quality, properly sorted result.

SG nut color sorters utilize high-resolution cameras to quickly classify different types and qualities of nuts. You simply set various visual parameters to get the desired output.

Our machines also come standard with one set of Near Infrared (NIR) cameras that provide high contrast pictures of the nuts for best accuracy. For nuts with shells, an X-ray camera can be installed to penetrate the shells, allowing quality control without the need to deshell.

Our rejection system has a 99% accuracy rating and high levels of throughput. This means you can sort many nuts efficiently and effectively.

We offer small to large sorting machines with two main designs: Belt-type and chute-type machines. The correct type will be chosen based on the characteristics of your nuts. In general, you will be using chute-type machines.

Nuts Color Sorter: The Ultimate FAQ Guide


1.Why should I use a color sorter for nuts sorting?

Sorting good nuts from bad by hand is unfeasible because of the quantity.

Color sorter machines can do the job of hundreds of humans per hour. It sorts nuts with high accuracy, efficiency, and minimizes wastage.

Our clients see a full return on investment in as little as 1 year. They often see a reduction of labor costs and maximized nut yield.


2. How do nut color sorter machines work?

After inputting raw material, the sorting machine uses cameras to take pictures of the material. The on-board software classifies it and sends signals to the rejection system. The rejection system will eject unacceptable materials while allowing good ore to go through. The sorted output can then be further re-sorted to minimize wastage.
