The Color Sorting Machine is invented for Farmers and Grains Processors

Around 1930, the idea of a machine able to sort by color was introduced in the US. By 1937, the first color sorting machine was made in England. The first color sorting machine was introduced to Japan in 1966 and the usage of these machines has since spread worldwide. Put simply, color sorting machines can detect and remove materials based on colors and visual elements not previously possible with conventional sorting machines.

Discolored or damaged rice and foreign substances could now be sorted out by these machines, thus the product quality significantly improved.  Recently, due to traceability issues, farmers themselves have started to purchase rice color sorting machine due to the demand of consumers who prefer to purchase directly from farmers.

NIR Sensors Used with Identification Algorithms for Completing Tasks of Plastic Sorting Methods

Near-Infrared (NIR) sensor technology coupled with highly sensitive algorithms are likely the most efficient and consistent plastic sorting technologies due to their high sorting accuracy in separating desired plastics from mixed waste, as well as sorting plastics by color and resin types. Identification algorithms then rapidly categorize the different “signatures” of polymers from their infrared spectra.

While other sensor based sorting technologies, such as x-ray, laser, and light emitting device (LED), are capable of distinguishing between colors and densities, NIR with identification algorithms is likely to be the most consistent, accurate, and time-efficient of the various sensor based sorting options in terms of sorting plastics. Lasers and LED have the ability to detect color differences but cannot determine the different resin types of plastics. X-ray technology can decipher plastics from non-plastics but it cannot distinguish different colors and resin types, therefore lessening its overall efficiency in effective plastic sorting. NIR sensors used with identification algorithms are able to consistently complete all necessary tasks in the sorting of plastics.

Tomato Processing System & Sorting Machine

When it comes to sorting tomatoes, the important ways to evaluate sorting systems is the gentle processing plus accuracy of color sorting and weight sizing. Most of tomatoes in market are fragile and delicate fruit so it deserves the special and careful handling systems to avoid the damage.

Tomatoes is normally be sorted on the basis of the color, weight, diameter (minimum or maximum) to detect the blemishes and drawbacks with a variety of packing options available. The complete processing systems include place packing single or double layer packs or semi-automated volume filling where the computer weighs each carton automatically before palletizing. The color sorting machine is the crucial invention that makes fruit packers find the extraordinarily good value to replace hand sorting and to make the final product consistently superior compared to hand packing.
