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. 

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.

The Steps of Coffee Processing, Sorting and Cleaning

The final steps in coffee processing involve removing the last layers of dry skin and remaining fruit residue from the now dry coffee, and cleaning and sorting it. These steps are often called dry milling to distinguish them from the steps that take place before drying, which collectively are called wet milling.
The first step in dry milling is removing what is left of the fruit from the bean, whether simply the crumbly parchment skin in the case of wet-processed coffee, the parchment skin and dried mucilage in the case of semi-dry-processed coffee, or the entire dry, leathery fruit covering in the case of dry-processed coffee.

Most fine coffee goes through a beans sorter machine that sort the coffee by density of bean and by bean size, all the while removing sticks, rocks, nails, and miscellaneous debris that may have become mixed with the coffee during drying. First machines blow the beans into the air; those that fall into bins closest to the air source are heaviest and biggest; the lightest (and likely defective) beans plus chaff are blown in the farthest bin. Other machines shake the beans through a series of sieves, sorting them by size. Finally, an ingenious machine called a gravity separator shakes the sized beans on a tilted table, so that the heaviest, densest and best vibrate to one side of the pulsating table, and the lightest to the other.
