A method of processing cattle feed products based on agricultural material, such as sugar beet pulp, citrus fruit pulp and peel, and material obtained in the fermentation of agricultural material, such as distiller's grain, which material is available after either a fermentation process or sugar leaching of beet pulp or after mechanical dewatering (pressing) or evaporation. To improve the nutrient value and general quality of the cattle feed product while at the same time improving the heat economy of the production process the invention proposes a method comprising the steps of preheating the material in steam, known as carrier steam, disintegrating the material in said steam for fragmentation thereof into uniform particle size, and drying the material particles in heat exchangers. Preferably the carrier steam is a part of the drying medium used in the process, that is, for heating and conveyance of the particles. The cattle feed processing steps may be performed in the order indicated or processed in any other suitable order. The cattle feed product/material is then separated from the carrier steam and cooled. The plant designed to perform the method includes a pressure vessel (5) to which moist cattle-feed material (1) is transported via a pressure lock (4), equipment (8, 10) for disintegration of the material to equalize the particle size, equipment (11) for drying the material and a pressure lock (14, 15) to discharge and separate the material from the carrier steam. |
