最近,我们试验成功了一种代替抽提试验的含油率测定法。这种方法,节约时间,约30～40分钟即可做一个,并节约苯、滤纸、酒精等许多较贵的试验品。但是在取料、试验操作过程中,必须细心,稍微不慎,就会影响效果;也必须注意安全,严防失火;特别是最后炒料(烧料)时,应在周围没有易燃品的试验室外进行。 Recently, we successfully tested an oil content test instead of an extraction test. This method, saving time, about 30 to 40 minutes to do one, and save benzene, filter paper, alcohol and many more expensive test items. However, in the process of picking and testing, we must carefully and slightly inadvertently, which will affect the result. We must also pay attention to safety and prevent fire; especially in the last frying material (burning material), there should be no flammable surrounding test Outdoor
