“…In the 1940s, gas-fired IR technology was firstly used for grain disinfestation. Frost et al discovered that the mortality rate increased with the temperature rise of insect pests (Frost et al, 1944). In the 1960s to 1980s, gas-fired IR method began to be investigated to kill different immature stages and adults of stored-grain pests (Cogburn 1967;Cogburn et al, 1971;Kirkpatrick and Tilton, 1972b;Tilton et al, 1983).…”

The objective of this study was to investigate the characteristics of adult Sitophilus zeamais and Tribolium castaneum, and the 21.1% dry base (d.b.) MC of rough rice by ATR-FTIR spectra, and determine the theoretical optimum infrared (IR) heating temperature of the tested samples. In laboratory experiments, a ceramic IR drying device was used to heat infested rough rice to research the mortality of Sitophilus zeamais and Tribolium castaneum, the drying characteristics of rough rice, and milling quality. The theoretical calculation optimum temperature of IR heating was 300 ˚C according to the results of FTIR spectra. In addition, the effects of the different IR radiation intensities and heated rough rice temperatures on mortality of insects, moisture removal, and milling quality were determined in this text. A high insect mortality, heating rate and corresponding high moisture removal were achieved by using IR heating. After heating, tempering process significantly increased insect mortality when the heated tempered rice temperature was less than 55 ˚C, and improve moisture removal and milling quality of rough rice during nature air cooling. When the rice heated under the IR radiation intensity of 2780 W/m 2 for 110 s, the rice temperature reached 60.2˚ ± 0.5˚C, 100% mortality of S. zeamais and T. castaneum, and 3.97 percentage points of moisture removal during the heating period after tempering and natural cooling. In addition, the high rice milling quality can be achieved after tempering treatment. Therefore, it can be concluded that the optimum conditions of simultaneous disinfestation and drying were 60 ˚C rice temperature under the IR radiation intensity of 2780 W/m 2 , followed by tempering and natural cooling.

This book, which consists of 13 chapters, provides fundamental and up-to-date published information on thermal treatments for the management of postharvest pests associated with agricultural commodity structures. Specific topics that are covered include: (i) regulatory issues for quarantine and phytosanitary treatments; (ii) basic information on temperature measurement, heat transfer, and thermal death kinetics of insects; (iii) biological responses of agricultural commodities and insect pests; (iv) biological responses of plants, insects and pathogens to heat; and (v) an introduction to current and potential quarantine treatments based on hot air, hot water, and radio frequency energy. This book should serve as an important resource for readers who are interested in knowledge, methods and strategies used in the development of environmentally friendly processes based on thermal energy. This book may also be suited for readers in the academe, industry and government.
