摘要
Abstract
To establish a simple,efficient,and applicable method for determining moisture in Feed-Grade stone powder,providing a reference for moisture detection and the evaluation of safety and hygiene indicators in feed-grade stone powder.Three commonly used moisture determination methods were employed:the national standard direct drying method,the national standard vacuum drying method,and the Karl Fischer volumetric method,Limestone powder samples collected from feed production enterprises and feed-grade stone powder across multiple provinces in China were categorized into three groups based on calcium content,with 10 samples per group.Experiments were conducted to identify a simple and practical moisture determination method suitable for feed-grade stone powder.Comparative experiments on the national standard direct drying method,national standard vacuum drying method,and Karl Fischer volumetric method showed are not much differencesin the results of moisture determination in feed-grade stone powder.The national standard reduced-pressure drying method offers higher precision,providing a reference for testing personnel in production or testing enterprises to determine the moisture content in eed-grade stone powder.关键词
