Effect of Heat Pipe-Based Low-Temperature Grain Storage Technology on Wheat Quality
To study the effect of heat pipe-based grain storehouse on grain storage,a heat pipe-based grain storehouse has been established in the paper.The variations of temperature,moisture,conductivity,catalase activity and fatty acid value have been studied.The results showed that during the one-year test cycle (September 2012-September 2013),compared with those of the traditional grain storehouse,the heat pipe-based grain storehouse had faster cooling velocity and longer low-temperature period.The moisture reduce was 0.12％ and the catalase activity reduced of 14 mgH2O2/g,which were respectively 0.11％ and 39.19％ lower than that of the control storehouse; the conductivity increased of 7.65 mgKOH/100g and fatty acid value improved of 5.1 μS/cm,which were respectively 42.48％,45.16％ lower than that of control storehouse.Finally,the low-temperature grain storage technology was effective in grain storage by reducing moisture,increasing fatty acid value,maintaining grain activity and preventing the deterioration of grain.This research provides a theoretical foundation and technical support for the practical application of heat pipe technology in large grain storehouse.
