The Ultimate Grain Color Sorter Buying Guide

There is a new crushing technique right now that helps to sort your items by color difference. Color sorting equipment helps you to detect the color of the products and separate them from the raw material using mechanical ejection devices. In this guide, you’re going to learn how granular things are sorted by grain color sorter Best part? Every process of sorting is according to the customer’s requirements. Let’s jump in to find out more about grain color sorter

Chapter 1: What is Color Sorter?

A grain color sorter is a machine that helps you to separate unwanted material with high sorting accuracy. That might sound complicated but it isn’t. Grain color sorted simply analyze, grade, and sort the granular particles according to the requirement.

What is the color sorter machine?

Color sorters or color sorting machine is equipment to classify items by their color difference using high-resolution CCD optical sensors.

Figure: SG Hot Grain Color Sorter with Five Chutes

You can use grain color sorter in food processing industries like wheat, rice, etc. Color sorters are the final stop of the products before packing. These machines work on vision-based sensors using a monochromatic or dichromatic high-resolution camera, sensitive ejectors, and efficient software which monitors the whole operation. Let’s check what magic color sorting machines perform to classify products from raw material.

Functions perform by grain color sorting machine

As you can see above color sorting machines help you to classify your products to increase your business revenue. Now the question arises in mind how grain color sorter process the food items.

  • First sorting items loaded in the feed hopper
  • It starts moving along the vibrating plates
  • After vibrating the plate, it moves to the sloping chute
  • High-resolution CCD cameras keenly check and grade the products
  • On the other hand, rejected items departed by the relevant ejectors in the grain color sorter.

In fact, this is the most efficient & precise way of sorting items with the color difference.

The color sorter mechanical structure

Do you know about the components included in the Grain color sorter? No? Don’t worry keep reading main components are the vibrating feeder, chute slide, light, feed hopper, background plate, CCD high-resolution camera, nozzle, air compressor, filters, and air purifiers, and ejectors. You know feeding hopers transfer the grains to vibratory feeders.

And the most interesting thing is vibration automatically arranges the granular particles in row or quo. With the constant speed of vibration, it accelerates through the chutes and falls into the detection sorting area. If you want to sort your products precisely the place with CCD high-resolution sensor helps to detect colors correctly.

Another important feature whenever you’ve humidity in your grains it may affect the color selection accuracy during the sorting process. Here area heater and fine drying system to remove humidity from grains.

Color sorter machine technology

Most people thought grain color sorter is really difficult to use but they’re wrong. Grain color sorter is an analog-based system that support digital processing. I already told you approximately all units are monochromatic or dichromatic and it’s totally based on manufacturers. Instead of using color lines grain, color sorter works with the signals coming from lighter or darker material flowing through the machine.

You must remember the color sorting machine have no understanding of the actual color of grains but monochromatic sorting works with contrast or black & white colors. At first monochromatic color sorter machine has an additional feature like NIR or InGaAs cameras. But some people referred to this technology as bi-chromatic sorters.

And these color sorter machines are also called dual-wavelength visible spectrum sorters. Although this looks like a dream in the future color sorting machines will work with actual color imaging. Machines will be able to detect red, green, and blue colors instead of black & white. And most interestingly future machines will detect human eye structure abs recognize 16 million colors.

Photoelectrical technology

Can you guess how many features are included in photoelectric technology? Well, if you guessed that’s great. That’s a lot but I want to share some of the highlights.

  • The cool high-resolution CCD image acquisition system
  • Light source- high quality
  • Unique slot configuration
  • Updated feeding system
  • The super processing power of the DSP+FPGA chip
  • The high-quality solenoid valve
  • Flexible mode and wide application scope
  • Easy to operate system configuration

Technically this is the most scientific but reasonable sorting system design which processes smoothly with the most intelligent algorithm.

How a color sorting machine works

You know the popular grain color sorter in the market CCD type color sorter and optical color sorters. The way you sort the products from the raw material is the color difference between good grains and bad grains. Are you ready to learn the working principle of grain color sorter? If so, then carry on reading.

color sorter working principle

First of all, the grain color sorter machine converts photo signals to electronic signals to detect good or bad products. You need to adjust the specific degree of electronic current to make granular particles safe. If you provide a safe limit of current then grains will successfully fall down to the accepted plates.

But if you provide a dangerous level of current the ejector will be driven to the outside panel, where all unwanted material arrived.
