DRAMINSKI GMM mini

Draminski GMM mini Capacitive Grain Moisture Tester: Core Engineering & Accuracy

The Dramiński GMM mini is a portable digital moisture meter developed by Draminski for quick agronomic and grain storage evaluations. The instrument uses high-frequency capacitive circuitry to determine dielectric permittivity in whole grains, seeds, and pulses, removing the need for manual grinding, sample weighing, or chemical reagents.

A single-chip microprocessor calculates moisture content while compensating for seed temperature fluctuations. Key hardware and firmware capabilities include:

• 33 Factory-Calibrated Crops: Dedicated curves for common wheat, durum, rye, triticale, spring barley, oats, corn (up to 43%), canola, soybean, sorghum, lupin, and paddy rice.
• Independent Curve Offset: Users can enter numerical modifications for each grain species via the membrane keypad to match the readings to internal lab oven drying standards.
• Calculation Averaging: The menu allows operators to average 2 to 30 consecutive measurements, smoothing out bulk sample variance during incoming grain inspections.
• Field-Serviceable Firmware: Mini-USB connectivity allows downloading firmware enhancements and supplementary crop calibrations directly from a Windows PC.

Field Verification, Elevator Reception, and Feed Processing Applications

Moisture content determines storage stability, susceptibility to mycotoxin formation, and commercial grain pricing. The GMM mini is used across several operational phases:

• Harvest Window Determination: In-field evaluation directly inside the tractor cab or combine hopper to avoid premature harvesting and elevated artificial drying costs.
• Silo and Grain Elevator Inward Inspection: Rapid gate checking of bulk truck deliveries before discharge to prevent pockets of damp grain from entering dry storage bins.
• Commercial Grain & Seed Trade: Instant verification during batch settlements and port transfers across GCC trading hubs where cargo temperature and moisture must comply with buyer contract terms.
• Feed Mills & Seed Warehousing: Routine monitoring of raw materials (corn, soy, barley) prior to extrusion, grinding, or long-term warehouse stacking under warm climates.

Specification Comparison: Dramiński GMM mini vs. Dramiński GMMpro

While both units measure whole grains using capacitive technology, the Draminski GMMpro adds an internal scale system for operations requiring automatic sample weight normalization:
