The present invention relates to a method for regulation of the temperature of a raw material, particularly ground fodder, which is supplied to a pellet mill by regulating the ratio between the quantity of steam supplied to the raw material and the quantity of raw material supplied to the pellet mill, a quantity of steam being supplied in proportion to the quantity of raw material, so that the proportion is in all essentials constant, whereupon the steam quantity is increased in proportion to the quantity of raw material, until the power consumption of the mill begins to rise, whereafter the quantity of steam is reduced, until the power consumption falls to its minimum, and this new proportion is then maintained during the continued operation. Hereby it is possible to produce forage pellets at the optimum point of the mill, and at the same time it is made sure that no gelatinization takes place. An increase of production of up to 40% over the previously known regulation plants can hereby be achieved.
