定温定时法测定粮食水分正确与否,与烘箱大小、样品盒多少、以及是否严格控制烘箱的温度和烘干时间有关。即要求被测定样品在规定的恒温干燥时间内,烘箱温度控制在标准法105℃(或普通法130℃,温度波动不超过±2℃)的温度范围内进行样品干燥。 Set the temperature method to determine the correctness of food moisture, and the size of the oven, the sample box number, and whether the strict control of the oven temperature and drying time. That is required to be measured samples in the specified constant temperature drying time, the oven temperature control in the standard 105 ℃ (or common law 130 ℃, the temperature fluctuations of ± 2 ℃) within the temperature range of sample drying.
