Sorting machine for grains

Types of sorting machines for grains

A sorting machine for grains comes in many types, each with its benefits and features. Here's a brief overview of the most popular grain sorting machines:

• Vibrating Screens

  The most common grain sorting machine. It uses vibration and screen perforation to separate grain by different characteristics. The machine is capable of separating grain by size, shape, and even weight. The sorted grain falls off the screen into different chutes.

• Air Classifiers

  This type of sorting machine uses air currents to separate grains by weight. Lighter grains will get blown away into a different chute while heavier ones fall down where they get collected.

  Very useful for separating organic matter such as shells and dried leaves.

• Color Sorters

  Advanced grain sorting machines that use camera and light technology. They can separate grains based on color, which is useful for identifying spoiled or contaminated grains.

  These types of machines can be programmed to identify specific colors and tend to be more expensive than other types of grain sorting machines.

• Optical Sorters

  Modern grain sorting machines that use cameras, lasers, and AI algorithms to separate grains based on color, size, shape, and texture. They provide a high level of accuracy and are suitable for sorting various types of grains, including rice, wheat, and corn.

• Suction Sorters

  Grain sorting machines that use suction to remove unwanted materials such as chaff, straw, and immature grains. They operate on the principle of different suction pressures required to lift various types of grains.

Specifications and Maintenance

Specifications

• Grain Capacity: The amount of grain the machine can work with is typically measured in tons or bushels and varies by machine size and design.
• Sorting Accuracy: Some machines can find and remove even 99% of bad grains, while others might only do 95% or less. More accurate machines tend to be more complex and costly. For example, optical sorting machines usually have a higher accuracy than air classifiers or custom screens.
• Grain Types: Certain machines do a better job of sorting out specific crops, such as corn, wheat, rice, oats, chickpeas, or soybeans. The design may have variable classifiers, custom screens, or other parameters that suit it for some grains versus others. For example, a grain classifier could have a special separator for food-grade corn versus one used for cottonseed separation.
• Replacement Parts: Some machines have common replacement parts, like basic air classifiers, that many technicians know how to install. Others may have unique components known only to specific manufacturers, such as certain advanced optic versions. Check the machine for repair kits and replacement parts before buying it so you know who can service it and what their expertise is.
• Production Line Features: Some grain sorters have extra functions built in, like automated packaging, that enhance a complete processing line compared to stand-alone systems. If the grain sorter is part of a bigger food-protection pipeline, consider how well its specs fit with those of the other machines involved in the workflow.

Maintenance

When handling grain, it is always better to repair it early, especially as humans are constantly going through and transporting resources like grain. Cleaning, calibrating, and making small adjustments to air classifiers can sort seeds early instead of letting them go further into the process where removing them is more complicated and costlier.

Because the grain separator is usually part of a bigger food production line, consider specialists who cover the whole line from start to finish. They will understand all the machines as whole systems instead of just as parts that can be dealt with independently. This view allows them to see all of its components working together and respond accordingly when things go wrong. They will be able to feel and listen to the machine and know how to code it for further efficiency, calibrating it up to its highest yield and sorting capacity.

Still, as basic maintenance of grain detectors, try to clean them daily or after every few batches to get used to the sorting requirements of different varieties, which may be neater or need more clarity. Try to calibrate it at least once a month—but if food production is at a critical level and many people depend upon it, do not let it spare more than a week or two of calibrating! At times of high usage, the classifier needs calibration every day. Try to identify the main classified food items that go through it and focus exclusively on those to keep the machine running efficiently.

Application Scenarios of Sorting Machines for Grains

When it comes to sorting grains, the machine serves many industries and applications. Here are some of the common uses of grain sorting machines.

Many breeding farms and agricultural producers use a grain sorter machine to sort normal-sized, high-quality grains for feed and human consumption. This includes working in rice paddies where grain sorter machines for rice are commonly used. Also, fruit and vegetable production industries leverage grain sorting machines when handling crops like nuts, green beans, and potatoes, among many others.

Small-scale grain sorters are popular because they can be mounted on various grain milling machines when milling crops like maize, wheat, rice, and sesame, to name a few. They are usually installed before the grinding units to ensure the intake of sorted grains. This improves the quality of flour produced.

Quality control inspection lines in food processing factories also utilize grain sorting machines. They help to identify and remove spoiled or undesirable food products to ensure the factory adheres to acceptable standards and the final product is safe for consumption.

Allied agriculture industries mostly use grain sorting machines for seeds. These machines correctly sort and package high-quality seeds for sale and planting purposes. The agricultural extension services also recommend sorted quality seeds to farmers because they yield better harvests.

Because grain sorting machines are automated, they are mostly used in large-scale agriculture-production oriented industries that prioritize efficiency, speed, and accuracy in the grain-sorting process.
