A variety ofshellers and hullersare available for processors of grains, beans, nuts, and pulses. To maximize the effectiveness and efficiency of these machines, it’s important tochoose the right equipmentand 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
Impact hullersremove 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.
圆柱形剥
Cylinder shellersare 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.
Conical Shellers
Ideal for cereal grains and pulses,conical shelling machinesuse 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
Roll shellersare 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.
Getting the Most Out of Your Equipment
Once you’ve selected the right type of equipment for your shelling or dehulling needs, be sure to choose products that have a reputation for durability, performance, and cost effectiveness. Prior to operation, follow these tips:
- Read and understand all manufacturer’s operating instructions, including recommendations for personal protective equipment. This will help ensure you’re using the machine as safely and effectively as possible.
- Use the appropriate settings and speed for the product you’re processing. If not specified by the manufacturer, identifying these may require some experimentation.
- Pre-sort和适当的清洁和dry the product before introducing it into the machine. Debris or nonconforming product could hinder efficiency or damage the machinery.
- Select high quality product to maximize machine efficiency and minimize waste.
- Keep the machinery clean and follow all manufacturer’s maintenance guidelines. Debris can cause clogs, increasing processing time and hurting your operation’s efficiency.
By following these tips, you can optimize efficiency, increasing processing times and yields while reducing waste.
