PROBLEM TO BE SOLVED: To prevent the deterioration of the quality of soybeans by an inexpensive method when shipping the soybeans and passing the soybeans through a high temperature region. SOLUTION: The soybeans are dried by cold air within a silo 1 before shipment to lower water contents of the soybeans. The temperature of cold air may be set by considering kinds of the soybeans, an outside air temperature and humidity, etc., at a temperature lower than a normal temperature within a range of 17 to 5°C, for instance. It is better to use cold air of 15 to 10°C to reduce damage to be imparted to physiological tissues of the soybeans. Because the water contents of the soybeans are generally about 13%, quality holding effects of the soybeans are obtained only if the soybeans are dried by cold air up to about 11% of the water contents. But when the soybeans are marine-transported across tropical regions in the vicinity of the equator, it is desirable that the soybeans are dried by cold air till the water contents of the soybeans become≤10%. The soybeans dried by cold air are hardly lowered in quality even if the soybeans are marine-transported across the tropical regions in the vicinity of the equator. COPYRIGHT: (C)2004,JPO&NCIPI
