Grain Grinding with Rotochopper Horizontal Grinders

| Grinders In Action

A Rotochopper horizontal grinder processing shell corn.

While some of the markets Rotochopper serves are large, others are more niche, and grain grinding is one of those cases. High moisture shelled corn presents a multitude of challenges during its processing—challenges that Rotochopper horizontal grinders are uniquely positioned to handle.

Because the window for grain grinding is so small, many companies find themselves taking advantage of the market of animal feed alongside their main business. With very precise size specifications and a short window of time to grind within, grinders used for high moisture shelled corn need to be at the top of the industry and dialed into the use case specifications to keep up.


The Challenges of Grinding High Moisture Shelled Corn

Why grind high moisture corn in the first place? While whole grains can pass right through livestock without digestion, a coarser grind can cause animals to pick out the “best parts” of the feed, missing out on important nutrition. A fine grind improves the digestibility of the starch and provides an even mixture that doesn’t allow livestock to pick out the choicest bits.

While grinding corn with a horizontal grinder carries a low risk of contaminants and damage to the machinery, high moisture shelled corn does possess several unique challenges. As mentioned above, size specifications for the end product are strict—it needs to be about the consistency of store-bought corn meal. High moisture shelled corn is already small, and unground kernels are essentially wasted profits, so the grind needs to be fine and consistent.

In addition, the corn needs to be harvested at a specific moisture content, so the window for processing is very short. Horizontal grinders need to be able to handle large amounts of corn quickly but without sacrificing quality and consistency.
