RN600 Automated Rice Grain Sorter

Automated Rice Grading, Now Carried Forward by the RN700E

The RN600 is no longer manufactured. Its current replacement is the RN700E Rice Quality Analyzer. The information below is retained for owners of existing units.

What the RN600 Did

• Physical separation, not just classification: the RN600 shined light on each grain of brown or polished rice, read color and (by transparency and reflection) shape, and physically separated the sample into five quality classes (even, cracked, immature, discolored, dead). This physical sorting set it apart from imaging analyzers that classify on screen without separating the grain.
• Batch throughput: up to 2000 grains per batch at roughly 12 kernels per second, with a percentage breakdown for each class displayed and recordable to an optional thermal printer.
• Adjustable grading: selection levels could be set and stored, letting an operator match the classification to their own grading criteria and apply it consistently.

Service and Replacement

The RN600 was backed by a One Year Total Care Warranty covering parts, labor, and specification compliance, with maintenance agreements available. Owners of existing units can reach Kett for service through our regional agents across the Americas, with calibration through Kett’s US and Tokyo laboratories.

Looking for the current model? The RN700E Rice Quality Analyzer carries forward the same objective, operator-independent grading of brown and milled rice. The RN700E grades by imaging; if your operation also needs physical separation of the graded sample, contact Kett to discuss current sorting options.
