The Minister of Agriculture of the Republic of Indonesia has set a target to achieve rice self-sufficiency by 2026. To realize this goal, the rice milling industry plays a crucial role in converting paddy into high-quality rice. One of the key factors determining the success of this process is the proper use of rice hulling rollers.
Rice hulling rollers are the main components of husker machines, functioning to remove the husk (hull) from paddy and produce rice. Optimal performance of rice hulling rollers results in a high husk removal rate, better rice yield, minimal broken grains, and a stable and efficient milling process.
Rice hulling rollers operate based on the principle of friction and differences in rotational speed between two opposing rollers. Paddy passing between the rollers while experiencing controlled pressure and friction, allowing the husk to be removed effectively without damaging the rice kernel. For optimal hulling performance, rice hulling rollers must have appropriate hardness, proper elasticity, and a surface capable of gripping paddy grains consistently.
To ensure maximum machine performance, selecting the right rice hulling roller should be done carefully by considering the following aspects:
- Material Quality. High-quality rice hulling rollers are made from specialized rubber compounds with a balanced formulation of hardness and elasticity. The right material effectively removes the husk without increasing the level of broken rice.
- Compatibility with Machine Capacity. Each rice milling machine has a different processing capacity. Therefore, rice hulling rollers must be matched to the machine capacity to ensure optimal performance and prevent premature wear.
- Dimensional Precision and Balance. Rollers with precise diameter and proper balance provide uniform hulling pressure, reduce machine vibration, and maintain consistent milling results.
- Service Life and Operational Efficiency. Rice hulling rollers with longer service life help reduce maintenance costs, minimize machine downtime, and improve long-term operational efficiency.
- Manufacturer Support and Proven Quality. Choosing rice hulling rollers from experienced manufacturers with clear quality standards ensures reliable performance and better technical support.
In addition to proper selection, maintenance of rice hulling rollers significantly affects machine performance and milling quality. Recommended maintenance practices include adjusting the roller gap according to machine specifications, maintaining ideal paddy moisture content before milling, conducting regular wear inspections, replacing rollers before excessive wear occurs, and avoiding machine operation beyond its designed capacity.
As part of its support for the national rice milling industry, PT Samudera Luas Paramacitra (SLP) manufactures high-quality rice hulling rollers in various brands, milling capacities up to 140 tonnes of dry rice grain, and roller sizes tailored to machine requirements.
With over 40 years of experience and ISO 9001 certification, PT Samudera Luas Paramacitra implements strict quality control from raw materials to finished products. Each roller undergoes a series of tests, including rheometer testing to control and ensure rubber compound quality, as well as visual and dimensional inspections to verify roller balance and hardness.
By using high-quality rice hulling rollers from PT Samudera Luas Paramacitra, rice milling plants can make a tangible contribution to achieving sustainable national rice self-sufficiency.
