Rice Color Sorter for Grains Processing Solutions

Jietai Technology offers the rice color sorter machine for effectively separating defects of black tipped, chalky, yellow, mouse droppings, immature grain, etc. Our color sorting machine for rice or grains is striving to get great solutions and high quality purified rice. Hence, it is possible to sort out miscellaneous cereals and all the foreign bodies contained in polished rice simultaneously the first time in the world.

Sorting accuracy at the speed of light using timing-designed cameras, products are scanned 100,000 times per second, creating sorting accuracy that is unachievable by any other method. Images are converted using high speed, 2048 pixel, and high-resolution CCD technology, for extreme accuracy in detecting down to 0.12mm defects. Our machines are capable of offering good accuracy and high sensitivity specifications to keep pace with the international standard. 

What is Use of Color Sorter Machine?

For food industry and plastic recycling, the color sorter machine is widely used to sorter different color of defective items. It can be applied for many materials such as tea, rice, cereal, grain, beans, nuts and non-food like plastic materials: PE, PVC, PP, etc. In general, the machine takes good advantage of CCD technology to color sorting solutions. The CCD in your camera has the function of measuring light at three separate wavelengths of red, green, and blue. That is to say, this is able to recognize color while separate defective items.

The system is added to special algorithm, such as shape selection, area algorithm in order to solve sorting problems like sorting some specific materials like beans according to their shapes, color, and area at the same time and make multi species color sorting to accomplish.

How Does Beans Color Sorter Work?

At present, there are several types of color sorter machines in the industry, from beans color sorter machine, rice color sorter machine to plastic color sorter machine. However, no matter which type is it, the main idea of working color sorter is the same. The basic working principle is: the color difference between good item which is purity and defective item (unwanted). To get started the sorting solution, the color sorter machine should translate the photo signal to electronic signal by photo-sensor and other complex element; then due to there is difference between good materials and bad materials, so corresponding there is also a difference good materials' electronic current. And we can adjust some degree electronic current is “safe” (good materials) and other is “dangerous” (defective or unwanted materials).

At last, when the electronic current is "safe", there is nothing happens and rice will successfully fall down to the accepted output; but if the electronic current is "dangerous", the ejector will be driven to blow away the bad or unwanted materials.

Amazed by Taipei Abundant Cultural, Gourmet Exploration

The general image of Taipei in my mind was filled with motorcycles and people in the narrow paths and sidewalks. However, Taipei journey in recent days broke my thoughts toward Taipei. I had great impression in Taipei, especially the apartment rentals we booked, the good taste we had and the historical cultures we admired.

Among of my travel in Taiwan, I spent my entire day exploring Taipei’s NationalPalaceMuseum, which is famous for its heritage, historical antiques and pieces of art. I fully indulged myself in the old days of Chinese history and experienced the world-renowned magnificent palace. For the last day of dinner, we had Din Tai Fung near our serviced hotel in Xinyi district to taste the exceptional gourmet, the elite of Chinese food, dumpling, dim sum items and hot and sour soup. All the dishes are very delicious! It made the best ending of my Taipei trip.

Features of Tea Color Sorter Machine

For the different shapes of tea leaves and tea stems, in combination with the spectral feature of image, the tea color sorter machine determines the shape and color algorithm to identify accurately defects in the materials. Different tea varieties are all available from original material, tea color sorting to final rejection to the end good product. This machine features to use the micro aberration distinguishing technology to effectively solve the sorting of tea with stems.

Otherwise, the tea color sorter machine adopts double layer and double sided with 360 degree view of identification to substantially increase the sorting performance. We use both the double-layer sorting system to complete sorting of materials and dedicated feed system ensuring uniformity of materials at one time to reduce damage to tea leaves.

The Color Sorting Technology for Cereal, Pulse, and Grain

Jietai Intelligent Technology equipped cereal color sorter machine view in both monochromatic ‘visible' light and NIR wavelength(s) simultaneously. NIR can be used to remove defective and foreign material that is the same visible color as the good cereal products. Examples include clear glass in white rice, brown stones in peanuts, mould damage in almonds, cob in corn grits, burnt material in flaked breakfast cereals, etc.

Foreign material can react differently to varying NIR wavelengths and therefore our tri-chromatic machines sort in two different mono wavelengths plus one NIR or one mono plus two different NIR wavelengths at the same time. Our tri-chromatic technology has an enviable reputation in the cereal and grains sorting industry, in many cases completely removing the need for manual inspection tables.

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.
