Tnixxif: how to dry rice after harvesting

Here is how to dry rice after harvesting, using PHilMech's sun drying guidance and University of Arkansas Extension's explanation of corn drying charts.

The drying steps How Tnixxif helps

From harvest to the next moisture reading

For sun drying paddy rice, these steps follow the Philippine Department of Agriculture's PHilMech Grain Drying manual, printed pages 1, 12, 13, 21 and 23.

Start promptly
PHilMech advises drying as soon as possible after harvest, ideally within 12 hours.
Spread a shallow layer
Use a mat, net, plastic sheet or concrete drying pavement. Spread the paddy 2 to 4 cm deep. Keep animals and other contaminants away.
Turn and protect it
Mix or turn the grain every 30 minutes. PHilMech says plastic sheets or canvas can protect spread paddy from sudden downpours. Monitor grain temperature and moisture while drying.
Measure before storage
Check grain moisture with a moisture meter or an oven test. PHilMech explains that longer storage needs lower moisture content. A count of sunny hours is not a moisture reading.

What does a grain drying humidity chart show?

PHilMech explains that grain gains or loses moisture until it reaches equilibrium with the air. Its paddy reference at 25°C shows how the result changes with humidity.

Paddy at 25°C, PHilMech Table 1
Air relative humidity	Equilibrium grain moisture (percent wet basis)
60%	12.20%
70%	13.40%
80%	14.80%
90%	16.70%

These are equilibrium values, not drying times or storage targets. Source: PHilMech, printed page 11.

Can I use a corn moisture drying chart for rice?

The University of Arkansas Extension chart is for corn. Its example says that air at 60°F and 70% relative humidity, forced through bulk corn, will not dry it below 15.7% moisture. That is a corn example, not a paddy target.

A forecast beside your measurements

Tnixxif helps plan outdoor drying around a measured batch and an hourly weather forecast. Choose a place, crop, moisture reading and spread details. The Drying horizon ranks windows over 72 hours. Live session shows the next action, while Evidence keeps your readings and session events.

Drying horizon with the woven weather graphic, a physical test reminder and the beginning of Ranked outdoor windows — **Drying horizon**The weather graphic and the start of the ranked windows, with a reminder to confirm moisture physically.

Live session showing Cover as the next action, elapsed exposure and the Record moisture button — **Live session**Cover is the next action in this example. Record moisture opens the entry for a physical reading.

Evidence showing two moisture readings and a Session started event — **Evidence**Two saved moisture readings and a Session started event. Measurements remain separate from estimates.

What the plan cannot confirm

A forecast cannot see shade, ground moisture, grain variety, broken kernels or a local shower. Tnixxif uses simplified models and shows estimates with uncertainty. It cannot confirm storage safety or promise that grain will not spoil. Its Model guide calls for local agricultural guidance and a calibrated moisture meter or oven test before storage.

The release notes document checks of the forecast, batch setup, session, readings and saved state. They do not document a farm trial comparing predicted drying with actual grain batches. Those software checks were not repeated for this story.
