Grain Cleaner Machines for Corn: Best Practices

22 April 2024

Selecting the Right Grain Cleaner for Corn.

Choosing the right grain cleaner machine is the first step towards achieving an efficient cleaning process. For corn, machines that incorporate grain sorting, seed separation, and aerodynamic seed separation technologies are highly effective. Aerodynamic grain cleaners and vibration grain cleaners are particularly suitable for corn due to their ability to handle large volumes and their efficiency in removing impurities, providing cleaning up to premium quality grains.

Here’s how you can leverage these machines for optimal corn cleaning:

  • Choose the Right Model:
    Metra offers various models designed to cater to different scales of corn cleaning needs, from small family farms to large commercial operations. For corn, specifically, the use of Aerodynamic Grain Cleaner (ADS) or Aerodynamic Grain Cleaner with cyclone dust collector (Ads-CDC) models is recommended, especially if there are cobs present. These models are adept at handling corn’s unique characteristics, providing thorough cleaning without damaging the kernels.
  • Maximize Efficiency with Proper Setup:
    Setting up your Metra grain cleaner correctly is crucial for maximizing efficiency. Position the cleaner so that corn is evenly distributed across the cleaning surface. This ensures each kernel passes through the cleaning process under optimal conditions, reducing waste and improving the quality of the output.
  • Utilize Cyclone Dust Collectors (CDC):
    For operations where dust and lightweight debris are a concern, integrating a Cyclone Dust Collector with your Metra grain cleaner can significantly improve the cleaning process. This add-on helps remove fine particles effectively, ensuring the corn is clean and ready for further processing or sale.
  • Address Specific Diseases and Impurities:
    Metra grain cleaners are particularly effective in removing diseases from corn, such as aflatoxin and vomitoxin. Through precise air separation technology, these machines can reduce contamination levels significantly, making the grain safer for animal feed and human consumption. This aspect is crucial for maintaining the health and safety standards of your product.
