Wheat flours with increased water absorbing capacity and method and apparatus for making the same

摘要

In the processing of wheat flour, it is ground while dry to increase the water take-up, using a dry stirring ball mill (11) rated at 20-300 kWh of milling energy per tonne of supplied flour, at a temperature of ≤ 60 degrees C or 30-50 degrees C. The wheat flour is milled continuously, in a circuit, or in batches. The mill is cooled by air, liquid nitrogen or liquid carbon dioxide, or the milling assembly is within a double-wall housing forming a cooling water jacket.
