Research progress in determination of specific heat of cereal and oilseed

比热是粮食干燥和储藏通风中热传递计算的重要工程参数。介绍了比热概念、经验计算公式及近年的主要测定方法。总结了谷物和油料比热测定值及其与含水率、温度及品种之间的关系。

The specific heat of grains is an important engineering parameter for calculating the heat transfer during drying and storing aeration. The concept of specific heat, empirical formulas for calculating and the recent main methods for its determination was introduced. The measurement of specific heat of cereal and oilseeds, and the relationship between the specific heat and moisture content, temperature, and the variety were summarized.
