F7 Sake Rice and Rice Koji Moisture Meter

Precise Moisture Control for Sake Rice Polishing and Koji Production

Sake brewing depends on tight moisture control at every stage, from polishing the rice to managing koji. The Riceter F7 measures moisture in sake polished rice, polished rice, brown rice, and sake rice koji, giving breweries and rice processors a single instrument for the readings that shape fermentation quality. Automatic temperature correction keeps results consistent through a working day on the production floor.

Measurements That Match the Brewing Process

• Sake rice polishing control: A dedicated sake polished rice calibration covers the lower moisture range that polishing produces, so moisture can be tracked as the rice is milled.
• Koji moisture you can read directly: A dedicated sake rice koji (karashi) calibration handles a sample type that general rice meters cannot measure, supporting consistent koji production.
• High-moisture refined rice: Calibrations extend into the higher moisture range for refined rice, where many testers lose reliability.
• Stable readings on the floor: Automatic temperature correction and automatic grain temperature correction hold accuracy as ambient and sample temperatures shift.

Built for Daily Use in the Brewery

The F7 runs on AA batteries and reads moisture directly on a backlit digital display, so it moves easily between the polishing room, the koji room, and receiving. Its compact benchtop housing and simple sample-tray workflow make it practical for repeated checks across a shift. Every F7 is backed by Kett’s One Year Total Care Warranty covering parts, labor, and specification compliance, with Maintenance Agreements available.
