A rice color sorting machine is a device that separates unwanted colored or deformed rice grains from the desired ones based on their color. It uses a high-resolution camera and a powerful computer to analyze rice grains' size, shape, and color. It then uses air jets to sort out the undesired rice grains. Several types of rice sorting machines are available to business buyers.
Traditional rice color sorter
The traditional color sorter sorts rice by color using a simple electronic system. It has a limited number of color-detecting sensors, so it can only sort rice based on a few colors. The traditional sorter is usually less expensive than modern varieties. However, its limited sorting ability might allow some undesired rice grains to pass through.
Optical rice color sorter
The optical sorter is more advanced because it has a large array of color-detecting sensors. As a result, it sorts rice grains by many different colors. Its electronic system is also more sophisticated, allowing for faster and more accurate sorting. However, the optical sorter is also more expensive than the traditional sorter.
Multispectral rice color sorter
This sorter uses multiple wavelengths of light to detect a wider range of colors and characteristics, allowing for more precise sorting. The sorter employs advanced imaging and analysis techniques to identify unwanted material. It then ejects them from the product stream. It can be more effective for particular products and applications but is also typically more expensive than other color sorters.
Machine learning-based rice color sorter
A sorter based on machine learning sorts food items by training a computer model to recognize different colors and patterns. This type of sorter may not be widely available yet, but it has the potential to become more common in the future. Sorters that employ machine learning can be more accurate than those that do not because a computer can learn and adapt to new information over time. However, they are also typically more expensive.
Rice CCD color sorter
This kind of sorter uses a charge-coupled device for the imaging part. A CCD is an electronic sensor technology that captures images and converts them to electric charges. The device then sorts rice based on the electric charges it has converted. Rice CCD cameras are efficient and recognize even the slightest color variations, so they are some of the most popular types of rice sorting machines. They are quite accurate, but they usually have a higher price tag.
Rice XML color sorter
XML sorters work similarly to CCD sorters, but they use a different imaging technology. These sorters also offer excellent precision in identifying unwanted colored rice. They might sort rice faster than their XML counterparts, but they will be slower than CCD sorters. Additionally, XML sorters are more affordable options for those who don't want to spend too much on a rice color sorting machine but still want to achieve a good level of accuracy.
The following table illustrates some specifications one can use to separate the varieties of rice grains using the machine. It also illustrates some maintenance tips for the rice sorter machine.
It is essential to inspect all the sorter machine parts, such as the hopper, conveyor belt, slide channel, sorting unit, and collector bins, for any signs of wear, damage, or obstruction. They should also be cleaned regularly to remove any rice residue that may collect and get stuck on them during the sorting process, especially once they have been refurbished from rice sorting machine manufacturers. For instance, one can use a soft brush or air to blow the dust off the camera lenses and lighting sources.
It is crucial to empty the reject and collection bins frequently to prevent them from overflowing and adversely affecting the rice colour sorting process. Overfilling of the bins may also cause cross-contamination of sorted rice grains.
Regularly inspect the air filters and cleaning fans to remove any dust and debris that may accumulate over time. To maintain optimal airflow and sorting accuracy, the air ducts should be inspected and cleaned on a regular basis to remove any dirt that might obstruct the pipes.
These two systems should also be regularly cleaned and inspected to maintain their optimal functioning. Typically, they should be wiped to remove any dust or debris that may block light pathways or camera lenses.
Rice sorting machines can be beneficial in the following industries:
Rice production and milling companies
The rice sorter machine is extremely useful in rice production and milling companies. Such companies use the machines to quickly and accurately classify rice according to its color. This helps eliminate discolored or damaged grains, improving the quality and grades of rice.
Food production and processing companies
Food production and processing companies that use rice as an ingredient or raw material often employ rice color sorters. These machines assist the companies in efficiently obtaining quality rice to create high-quality food items.
Export companies for agricultural products
Export companies for agricultural products, such as rice, chicory seeds, coffee beans, sesame seeds, and beans, among others, use rice sorting machines to ensure the quality and uniformity of their products to be exported. By doing so, they meet international standards and gain the trust of foreign customers.
Dealership companies for agricultural products
Dealership agricultural companies sort out their agricultural products with color sorters to satisfy the diverse needs of their customers. The company can provide its customers with a wide range of options by sorting out and classifying the rice by color.
Restaurants and catering services
Considerable quantities of rice are used by the catering services and restaurants. Therefore, these services sort out their rice to remove impurities and unidentifiable objects by using rice color sorting machines. This guarantees the safety and quality of the food served to customers.
Shopping marts and retail stores
When dealing with products such as rice, retail and shopping marts make use of rice sorting machines. This allows them to sort and package different types of rice according to customer preferences by brand, quality, and appearance.
Research institutes and laboratories
Several research institutes and laboratories use rice sorting machines to carry out tasks related to rice quality analysis and classification. Such companies usually choose advanced models with sophisticated sorting functions in order to collect data and examine various rice characteristics.
Choosing a proper rice colour sort machine entails considering several factors to find a machine well-suited to sorting rice effectively. These factors involve the sorter's capacity, accuracy, and detecting parameters, among others.
Sorting Parameters
When selecting a rice sorter machine, it's crucial to match its detection capabilities to the target population. Some machines can identify color, shape, and size, providing a comprehensive sorting solution.
Capacity and Efficiency
The sorting machine's processing capacity must align with the rice production line's required throughput. Choosing a machine with the right capacity ensures efficient sorting, minimizing bottlenecks in the production process.
Accuracy and Precision
Selecting a rice sorter with a proven sorting accuracy helps achieve the desired product quality. Higher sorting precision reduces the quantity of good rice rejected and contaminated rice retained.
Technology
A variety of technologies, including mechanical, electronic, and optical sorting machines, are available. It's crucial to research their advantages and disadvantages before making a choice.
Cost-effectiveness
When choosing a rice sorter machine, it's vital to consider the overall cost of ownership, which includes purchase price, operation and maintenance costs, and any additional expenses over the machine's lifespan. It's important to ensure that the chosen machine offers a good balance between performance and cost, maximizing long-term value.
Q1: What types of rice food does the rice sorter machine work on?
A1: The rice sorter machine works on all types of rice, including basmati, white, brown, jasmine, long grain, parboiled, wild, and red rice.
Q2: How does a rice color sorter machine increase profit margins for a business?
A2: When outputting only quality rice, the machine helps create a high demand for the product, and expensive pure rice varieties can yield even higher profits.
Q3: How intelligent are modern rice sorting machines?
A3: Current rice sorting machines are automated. They have different software that allows them to detect color variations in rice grains accurately. Modern machines have AI and optical sensors for precise sorting and can sort cameras faster than humans.
