Several factors affect the hulling ratio and quality of rice grains during hulling by rubber rollers, including structural parameters such as hardness of rubber roll, its diameter and clearance between the rolls, and their differential speed, and operating parameters such as adjusting the rolling force, feeding velocity and uniformity, and husking time.rubbu roll However, the underlying mechanism of grain breakage during hulling by rubber rollers has not been clarified yet.
In this study, the mechanisms of the hulling process by rubber rollers in a laboratory-scale experimental huller were investigated with the aid of quasi-static compression, three-point bending, and compression–shear tests. The results show that the hulling mechanism by rubber rolls involves flexible compression, which produces a rotational effect on grains and subsequently shear and bending failures. This is contrary to the conventional idea that rigid compression mainly breaks the grains and does not generate shear failure.
Rubber rolls are tough and cost-effective flooring solution for large areas. They are easy to install, and no adhesives are needed to keep them in place. To keep them looking good, just sweep regularly and clean them with a pH-neutral cleaner.
