摘要

Infrared drying technology, as an emerging option for rice drying, has attracted increasing attention for its process parameter optimization in recent years. This article systematically reviews relevant literature from the past 15 years, focusing on the mechanisms by which key parameters—including nonthermal pretreatment, radiation intensity, bed thickness, and tempering processes—affect drying kinetics and quality. The results reveal that existing studies generally lack theoretical analysis of the spectral matching between infrared characteristics and rice’s wave-absorption capacity, whereas ultrasonic pretreatment demonstrates superior advantages over other technologies in enhancing drying quality and technical maturity. After analyzing drying evaluation metrics used in existing literature and establishing unified criteria, this article recalculates published data to identify optimization directions for input parameters in infrared rice drying equipment. These directions include dynamically adjusting radiation intensity based on drying stages divided according to moisture migration patterns, implementing phase-specific tempering strategies, and determining the critical bed thickness threshold (12 mm) through identification of the turning point in relationships between bed thickness and rice appearance/milling quality. This article describes connections between equipment input parameters and rice drying characteristics, providing theoretical references for infrared drying process optimization.
