摘要： A process for measuring the liquid absorption capacity of a powder includes the step of spraying a liquid in the form of a spray cone at a constant throughput from at least one spraying device onto a powder being stirred in the mixing chamber of a mixer, the powder filing between 10 to 80% of the mixing chamber. The torque of the stirrer of the mixer is measured both before and during the spraying step, and from this measurement both a maximum level of the torque and the time difference between the beginning of the spraying step and the time when the maximum level is reached are determined. An amount of liquid absorption of the powder is then determined based upon the liquid mass which is sprayed during that time difference.
