    • A process and an apparatus are described for adding additives during the conditioning of animal feed. The feed is transferred from a container (1) into a conditioner (3) via a feed screw (2) at an inlet point (M). In the conditioner (3), the feed is transported by a mixing screw (12) from an inlet point (M) along a path (A) to an exit point (N), and is exposed to vapor in the course of this. One or more additives (5) which are introduced into the conditioner (3) through one or more ports (10) are added to the feed which, has passed through x% of the path (A) in the conditioner (3). The feed and the additives (5) added through one or more ports (10) are mixed on the remaining (100-x)% of the path (A) to form a mixture (6). The mixture (6) leaving the conditioner (3) at the exit point (N) is transferred to a pelleting press (7), where the mixture (6) is formed into pellets (8). The pellets (8) are finally transferred to a cooling device (9). The additives, in particular enzymes, vitamins, carotenoids and antibiotics, are not added to the main feed components until toward the end of the conditioning step. In this manner, these relatively heat-labile substances are exposed to elevated temperatures only for a relatively short time and experience much less stress than would be the case for complete passage through the conditioning unit.
    • 描述了在动物饲料调理期间添加添加剂的方法和装置。 进料通过进料螺杆(2)在入口点(M)从容器(1)转移到调节器(3)中。 在调节器(3)中,进料通过混合螺杆(12)从入口点(M)沿着路径(A)输送到出口点(N),并在该过程中暴露于蒸汽。 通过一个或多个端口(10)引入到调节器(3)中的一种或多种添加剂(5)被添加到已经通过调节器(3)中的路径(A)的x%的进料中。 通过一个或多个端口(10)添加的进料和添加剂(5)在路径(A)的剩余(100-x)%上混合以形成混合物(6)。 在出口点(N)离开调节剂(3)的混合物(6)被转移到造粒机(7),其中混合物(6)形成颗粒(8)。 颗粒(8)最终转移到冷却装置(9)中。添加剂,特别是酶,维生素,类胡萝卜素和抗生素,直到直到调理步骤结束时才被添加到主要进料组分中。 以这种方式,这些相对热不稳定的物质仅在相对短的时间内暴露于升高的温度,并且经受比完全通过调节单元的情况更少的压力。
