Rice polisher
Precision laboratory rice polisher designed to uniformly polish dehusked rice samples, enabling accurate assessment of whiteness, appearance, and milling quality.
What is Rice polisher?
The Laboratory Rice Polisher (often referred to as a Lab Whitener) is a critical analytical tool used to assess the milling characteristics and commercial potential of dehusked brown rice. Operating via a precision-engineered abrasive milling chamber, the machine gently but effectively strips away the outer bran layers to produce polished white rice.
This equipment is an indispensable asset for quality control and yield optimization; it enables operators to establish the exact milling times and abrasive pressures required to achieve specific whiteness grades while preserving the structural integrity of the kernel. By generating accurate head rice yield (HRY) data in the laboratory, production facilities can seamlessly translate these parameters to high-capacity commercial lines, thereby preventing over-milling, reducing energy waste, and ensuring the final product meets strict export and domestic market standards.
Common Applications
Commercial Rice Milling Facilities
Used for continuous sampling, calculating exact milling degrees, and calibrating high-volume commercial whiteners to prevent grain loss.
Grain Testing & Certification Laboratories
Essential for verifying grain whiteness, transparency, and overall milling quality against stringent international trade specifications.
Agricultural Breeding Programs
Utilized by researchers and agronomists to evaluate the milling traits, kernel strength, and bran thickness of newly developed rice cultivars.
Quality Assurance (QA) Departments
Crucial for preparing standardized, polished grain samples for subsequent inspection by automated optical color sorters or chemical moisture analysis.

Programmable Digital Timer
Features a highly accurate digital timing interface that automatically halts the polishing process at the exact specified duration. This ensures total repeatability and eliminates human error across multiple test batches for standardized milling degree analysis.
Low-Friction Abrasive Chamber
Utilizes a specialized abrasive rotor designed to peel away bran layers with minimal frictional heat generation. This significantly reduces thermal stress on the grain, preserving kernel integrity and preventing artificial breakage during testing.
Rapid-Release Sample Tray
Designed with an ergonomic, quick-release collection drawer that allows technicians to retrieve polished samples instantly without residual cross-contamination. This streamlines the workflow and accelerates high-throughput testing cycles in demanding QA environments.
