Drying checkpoint
Measurement boundaries
Weight change, room RH and subjective stem feel are not substitutes for a validated moisture or water-activity measurement when product safety or storage stability must be established.
Staged dry / cure program
Build a repeatable three-stage environmental program. “Slope” means gradually transition between stage setpoints; “Step” means hold each stage until the next stage begins. These are planning targets, not hardware commands.
| Stage | Duration (h) | Temperature °C | Dew point °C | Calculated RH |
|---|---|---|---|---|
| Dry | — | |||
| Cure | — | |||
| Store | — |
Actual vs active program
Comparison uses the current staged program inputs and elapsed hours. Step mode holds each stage setpoint; slope mode linearly transitions toward the next stage setpoint during the entered stage duration. These are program comparisons, not product-safety limits.
Vapor-pressure & water-activity context
Room vapor pressure is calculated from measured room temperature and RH. Vapor-pressure deficit here means the air saturation deficit at room temperature; it is not leaf VPD. Measured water activity is reported separately because product aw cannot be inferred from room RH or weight loss alone.
Water activity requires an appropriate measurement method; equilibrium RH ≈ aw × 100 only describes an equilibrium relationship and is not a substitute for direct product measurement.
Dry / cure trend
Review a saved lot across time. Temperature, dew point and RH can overlay the program target that was saved with each checkpoint; weight and water-activity views remain measurement-only.
Save at least two checkpoints to build a long-history trend.
Cross-lot comparison
Compare the full saved run summary plus the latest endpoint for two lots. Differences in sampling frequency, elapsed coverage, starting material, measurement method and program mean these values are context—not proof that one drying program is better.

Connected dry / cure provider
Load normalized temperature, RH, dew-point-capable telemetry, and water activity from the same-origin provider gateway when a compatible provider/device is configured. Provider credentials remain on the server. This page performs read-only requests and never controls drying hardware.
This requires the same-origin telemetry gateway to be deployed with provider credentials stored on the server.
