Rice Freshness Meter — Objective, Per-Kernel Freshness Grading by pH
The RN820 measures the freshness of milled rice kernel by kernel, replacing subjective judgment with an objective, repeatable freshness value that buyers and sellers can speak about in the same terms.
Every-kernel evaluation: reads freshness on each kernel rather than judging the bulk sample, surfacing variation a single bulk reading hides.
Graphical results: per-kernel values, histogram, and distribution chart make the freshness profile of a lot easy to read and compare.
Shared freshness language: a standardized five-rank classification gives suppliers and purchasers a common, defensible basis for grading freshness.
Records and export: statistics export to a spreadsheet for record-keeping and lot-to-lot comparison.
Automated Rice Grain Sorter — Physically Separates Brown and Milled Rice Into Five Quality Classes
The RN600 images each kernel of brown or polished rice and physically sorts the sample into five quality classes, replacing tedious manual separation with an automated, repeatable process matched to the grading criteria you set.
Physical kernel sorting: separates the sample into five classes (even, cracked, immature, discolored, dead), not image classification alone.
Batch throughput: up to 2000 grains per batch at roughly 12 kernels per second, with a percentage breakdown per class.
Adjustable selection levels: classification thresholds can be set and stored to match your grading criteria.
Optical Rice Sorter — Images and Physically Sorts Brown and Milled Rice by Quality Class
The RN500 images each kernel of brown or milled rice and classifies it into quality classes against grading criteria, giving rice mills and inspection operations an objective alternative to manual grading. It is no longer manufactured. The RN700E Rice Quality Analyzer is its current replacement.
Optical sorting into bins: images each kernel, then physically separates brown rice into five classes and milled rice into four — not on-screen classification alone.
Adjustable criteria: classification thresholds can be set and stored to match your grading standard.
Built-in reference plate: a standard reference plate keeps classification stable and operator-independent over time.
PC-Based Rice Quality Analyzer — Per-Kernel Imaging and Classification
The RN300 images each kernel on a flatbed scanner and classifies brown and milled rice against the grading criteria you set, with results correlated one-to-one to the on-screen image for review and verification.
Per-kernel imaging: each kernel scanned and classified, with image and data correlated one to one for review and verification.
Configurable classification: grade against standard or customized criteria, with results shown numerically and optically.
Data export: results export to Excel, up to 10,000 records, with an included thermal printer.
Standalone Rice Quality Analyzer — Grade Against Your Own Standard, No PC Required, 1000 Grains in 40 Seconds
Consistent grade assessment that does not depend on who is reading the sample. The RN700E captures three images of every kernel and classifies it against the grading standard you set, replacing the subjectivity and fatigue of manual inspection with results that repeat across operators, shifts, and locations.
Grade to the standard that governs your trade: set and store your own classification criteria, then measure every sample against it the same way, every time.
Traceable, operator-independent results: each grade traces back to the criteria you defined, not to whoever read the sample.
Fast and self-contained: approximately 1000 grains in 40 seconds, with no laptop, scanner, or external computer to set up or maintain.
Part of a complete rice-evaluation system: pairs with Kett moisture, composition, and whiteness instruments for full sample assessment from one source.
