HOW DOES A GRAIN CLEANER WORK
A grain cleaner is an essential agricultural machine designed to improve the quality and value of harvested grain by removing unwanted materials. It works through a series of mechanical processes that separate clean grain from impurities such as dust, straw, chaff, stones, weed seeds, and damaged kernels. The process begins with feeding the harvested grain into the machine. The first stage often involves a set of vibrating screens or sieves that separate particles based on size. Large impurities like sticks and clumps are removed by coarse screens, while smaller unwanted particles pass through finer screens.
Next, the grain moves into the aspiration system. This uses a controlled airflow to lift and remove lighter materials, such as dust, husks, or dried leaves, which are blown away and collected separately. After aspiration, gravity separation may be applied. In this step, grains pass over inclined vibrating surfaces or air-based gravity tables that help distinguish heavier, healthier kernels from lighter, damaged ones.
Some advanced grain cleaners also use magnetic separators to remove metal particles or optical sensors to detect and remove discolored or moldy grains. The end result is a batch of clean, uniform grain that is better suited for storage, milling, or sale. Grain cleaning enhances food safety, prolongs shelf life, and helps meet market or export standards.
WHICH MACHINE IS USED TO CLEAN WHEAT
To clean wheat effectively, various machines are used in combination, depending on the scale and quality requirements. The most common machine used is the wheat cleaning machine or grain cleaner, which may include several components: pre-cleaner, vibrating separator, gravity separator, aspirator, and sometimes a destoner or magnetic separator.
The cleaning process usually begins with a pre-cleaner, which removes large impurities like sticks, straw, and stones. Then, the wheat goes through a vibrating screen separator, which uses different-sized sieves to sort materials by size. Larger particles stay on top, while smaller debris falls through. After that, an aspirator uses air flow to suck out light impurities such as dust, chaff, or dried leaves.
Next, a gravity separator may be used to separate good wheat kernels from damaged or shriveled ones based on weight. For more precise cleaning, a destoner removes stones that are similar in size to wheat but heavier. In some modern systems, a magnetic separator is also included to eliminate any metal fragments.
In advanced milling operations, color sorters or optical sorters are used to remove discolored, moldy, or diseased grains. These machines ensure that only high-quality wheat is processed for flour production.
Overall, wheat cleaning is a multi-stage process that relies on a combination of machines to ensure purity, safety, and market readiness.
