A variety of shellers and hullers are available for processors of grains, beans, nuts, and pulses. To maximize the effectiveness and efficiency of these machines, it’s important to choose the right equipment and settings for your specific needs, use only high quality, properly dried product, and follow all manufacturer’s instructions for operation and maintenance. In this article, we’ll look at several types of shellers and hullers and how to get the most out of them.
Impact hullers remove the hulls from products such as oats, sunflower seeds, hemp, spelt, einkorn, millet, and buckwheat by using centrifugal force to impact the grains or seeds against a hard surface. Inside the centrifugal wheel, the grains or seeds are aligned and thrown against the impact ring. Impact hullers often feature adjustable impact rings, which may be available in various materials to accommodate different types of grains.
Cylinder shellers are used to shell or debran grains and pulses including wheat, durum, barley, millet, sorghum, peas, chickpeas, and lentils. They work by abrading the product against abrasive discs to remove the hulls or bran. The product is fed into the chamber via a feed screw and discharges through an adjustable counter-pressure plate. Removed bran or husks are channeled through a perforated screen using aspiration, which both cools the product and helps remove dust and particles.
Ideal for cereal grains and pulses, conical shelling machines use adjustable conical stones to remove hulls gently yet effectively and can also treat grain surfaces. Depending on the setting chosen, the sheller can remove husks, bran, and impurities.
Roll shellers are a great solution for all types of rice. These units use rubber rolls to remove hulls. Rubber roll shellers are especially useful when there is a need for careful, high capacity yet cost-effective shelling.
