Development of Physical and Optical Methods for In-shell Brazil Nuts Sorting and Aflatoxin Reduction
Bibliographic record
Abstract
Physical methods for mechanically in-shell Brazil nut sorting by color, size, density and inner deterioration weredeveloped to assess nut quality and reduce aflatoxin contamination. Nuts were able to be sorted by color utilizing thestandard shell chromaticity components L*, a* and b* at ranges of 31.51 to 48.64, 4.09 to 10.07 and 11.90 to 22.95,respectively. It produced a homogeneous color batch and segregated the off-standard ones (darkest, lightest and stained).By size sorting utilizing three oval sectioned trays with the following dimensions 40x25, 35x23 and 20x19.5 mm[length x width] and vibration, nuts were sorted into three sizes Groups: I, II and III for large, medium and small,respectively. Through density sorting the light nuts (shell/nut

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
