<p>Flour is first introduced into a turbine mixer, the turbine is rotated at a suitable speed for mixing, and the lecithin is then introduced in a single operation into the mixer, the lecithin being maintained at a temperature of no more than +8 DEG C. The lecithin may for this purpose be brought to a temperature of between +5 DEG C and +8 DEG C, simply by being kept in containers within this temperature range, or alternatively its temperature may be brought to this range by incorporating dry ice therein. In this way a pulverulent mixture is obtained, having a fine, regular particle size distribution, and free from lumps.</p> |
