Hardness and structure tester
The Hardness and Structure Tester is used in grain mills for testing and recording the grain hardness of e.g. wheat. The results provide useful information about the necessity of technological treatment (conditioning/drying) of the grain charge prior to milling. Furthermore, the entire milling process can be optimized if the parameter „grain hardness“, which is decisive for milling, is known early. The milling results can be improved and yield can be increased.
The device also enables an accurate evaluation of the hardness of a malt on laboratory scale. When combining the determination of the hardness with the mash test on coarsely ground grain, a clear conception is attained about the solubility of malt. This information is of important value for the brewer for the grinding and mashing process in the brewing house.
The device is attached to the Brabender Farinograph instead of a kneader.
The hardness of a malt is evaluated within only a few minutes by passing the ground sample through the hardness test and recording the resistance of the material by means
of a torque-time-diagram. The measure for the mellowness of a malt is the area of the diagram as the result of capacity and time which is proportional to the power required to crush a certain quantity of malt.
