Experimental study of the influence of using a dehumidifier on the moisture content of stored wheat

Abstract

High moisture content wheat kernels are subject to elevated respiration rates due to enzyme activity and mold growth which reduce the dry grain and may produce sufficient energy to be harmful to wheat quality. Grain aeration provides a powerful non-chemical stored grain insect management. Currently, aeration is a suitable and economical device to overcome this problem. Moisture management is vital to prevent spoilage in stored grain. The objective of this study is to investigate the influence of using low relative humidity aeration on the wheat moisture content. Results shows that dehumidification of blown air had greater potential for decreasing relative humidity of interstitial air and wheat moisture at 30°C temperature and relative humidity of 40%, 50% and 60%.
