Study Notes
PAES 203: Agricultural Machinery - Moisture Content Determination for Rice and Corn
- Formulated by Agricultural Machinery Testing and Evaluation Center (AMTEC) through the project "Standardization of Postharvest Machinery Testing and Evaluation" funded by the Bureau of Postharvest Research and Extension (BPRE) of the Department of Agriculture (DA)
- Reviewed by the Study Team for the Formulation of Standards for Grain Dryer and the Technical Committee on Postharvest Machinery
Standard Specifications
- Calibration procedures to be followed
- Methods of sample size reduction
- Grain sampling procedures
- Procedures on moisture content determination during the test

- NFA Standard Calibration Procedure - Grains Meter Calibration for Standard Laboratory Procedure
Apparatus
- Analytical balance with accuracy of ± 0.3 g
- Desiccator with silica gel
- Laboratory mill with characteristics:
- Made of material that does not absorb moisture
- Easy to clean with little dead space
- Enables rapid and uniform grinding without heat development and minimal air contact
- Moisture dishes (aluminum/pyrex glass) with lid and diameter of at least 50 mm
- Ventilated drying oven with regulated temperature range
- Secondary moisture meters (e.g. capacitance type, resistance type)
- Sampling apparatus (e.g. sack-type spears, triers, shovels)
Calibration and Sample Size Reduction
- Moisture meter calibration: every 6 months following procedures in Annex A
- Sample size reduction methods:
- Using sample divider: bulk sample poured into hopper, divided into collecting bins, and mixed to form a sub-bulk sample
- Through coning and quartering: dividing sample into smaller parts, discarding every other sample, and mixing remaining grains
