Understanding how Feathra Relay works transforms how you manage every grain lot from fill date through final movement
Feathra Relay maintains complete offline functionality by design. Every calculation runs locally on your device with no network dependency. Your grain lot data never leaves your phone, preserving operational privacy for sensitive harvest information. The developer focused on agricultural science accuracy, implementing commodity-specific sorption isotherms that reflect how different grains reach equilibrium moisture at identical temperature and humidity conditions.
Every feature serves the critical task of preventing grain spoilage before visible damage occurs
Feathra Relay calculates deterioration based on the fundamental principle that grain respiration consumes dry matter irreversibly. The application tracks time-weighted exposure to damaging conditions from the moment you log a lot. Unlike simple averages, the interpolation engine identifies localized hot spots where moisture and temperature combine to accelerate fungal growth.
The hourly evaluation system categorizes each ambient hour as cool, dry, wet, or idle based on whether running your fan moves conditions in the desired direction. Cool hours lower temperature without rewetting. Dry hours reduce moisture. Wet hours increase water activity and accelerate spoilage. The planner finds optimal contiguous run windows and quantifies the cost in spoilage days before you commit fan operation.
When you mix lots with different storage histories, the calculator works on dry-matter basis rather than averaging wet-basis percentages. This prevents the dangerous miscalculation where mixing damp grain into very dry grain appears safe on simple averages but actually creates high equilibrium moisture that drives rapid deterioration. The mass-weighted loss carries through to the blended lot.
Professional storage management demands tools that account for real-world complexity
Transform scattered probe readings into a complete bin profile. The interpolation shows temperature and moisture gradients across the grain mass, revealing dangerous spots that simple averages hide. Track the specific cell combination driving your spoilage clock.
Watch dry-matter loss accumulate from fill date based on actual time-weighted conditions. Cooling stops the clock but cannot rewind consumed storage life. The countdown shows remaining days to your threshold percentage with confidence bands when probe samples disagree.
Evaluate your entire ambient week to find optimal aeration windows. Each hour receives classification as cool, dry, wet, or idle. The planner identifies the best contiguous run period and calculates how many spoilage days a poor decision costs before you operate fans.
Track which storage organisms pose immediate danger at current bin conditions. Coverage spans Aspergillus glaucus through Penicillium species with timeline estimates to visible growth. Water activity determines which organism leads as conditions change.
Dedicated sorption isotherms for maize, hard wheat, soft wheat, barley, rough rice, and soybean ensure that identical moisture percentages produce correct water activity for each grain type. What matters for storage is equilibrium relative humidity, not just moisture content.
Preserve storage history when mixing lots by working on bone-dry basis rather than averaging wet percentages. The calculator carries mass-weighted loss through the blend and prevents the dangerous equilibrium moisture rise that occurs when wet grain enters very dry grain.
