Abstract

In the production of coloured powders, for incorporation in a large bulk of cereal flour or the like to be employed in the colouring of sausage meats, meat and fish pastes and the like, by spraying a warm aqueous solution of colouring material upon an agitated mass of starch and drying by heating, as described in Specifications 253,992 and 269,796, [both in Class 49], the drying is effected by drawing air over the starch and at least the agitating means is operated electrically, the heating, agitating and drying being terminated when the electrical power consumption, which rises upon spraying the starch with the aqueous solution, again falls to, or slightly below, the value for agitating the starch before spraying. The means for heating and for air suction may also be operated electrically.
