Pressure conditioning with the KAHL Annular Gap Expander The conditioning technique for improving the feed quality EXPANDAT ® hygienic biological structurized homogeneous

The Annular Gap Expander improves the product quality and the efficiency of the compound feed production The expander technology is one of the best and most comprehensive conditioning methods for compound feed and individual components. The hydraulically adjustable cone at the outlet together with the outlet ring form the patented annular gap. By means of adjusting the cone, the pressure, the intensity of kneading, the product heating, and the energy consumption can be controlled and programmed continuously and instantaneously. The maximum pressure is about 40 bar, the operating temperatures...

The multiple possibilities of variation concerning size and drive power allow for an optimum design of the KAHL expander for the requested production capacity. ESEP is the KAHL control and regulation system for automatic operation of the expander. Addition of large quantities of liquids Larger quantities of liquids, such as fat, molasses, vinasse and fish solubles, can be added to the expander. Effects on pelleting Expanded mixtures increase the press capacity. Pellet hardness and fines can be controlled by adjusting the parameters. Starch modification The treatment of the product under pressure,...
