Barley and wheat are stored in bulk storage silos (4,5) and are drawn as required into a hammermill (6) having a fine mesh to produce a very fine powder output, in turn delivered to batch supply containers (10, 11). Various other solids are received in a pre-milled condition and are also stored in various containers (12, 13, 14). Water is heated to 70°C. Citric acid production yeast by-product is pumped into a storage tank 31 where it is continuously agitated. Meat and bone meal stick water having an oil content of less than 3% is stored and heated with a continuous agitation in a tank 32. Glass-lined tanks (31,32) are used for yeast and stick water storage and agitation. The liquid raw material delivery order to a mixing tank (17, 18) is stick water, yeast by-product and water. This provides an homogenous mix in which the oil in the stick water is dispersed and the various contents are thoroughly mixed before addition of the solids. Both input and output of the raw materials and feed respectively is controlled by use of load cells on the mixing tanks. This helps to provide for re-circulation of the output feed to detect leaks and for control of delay times between different raw material delivery stages. |
