The invention relates to a method for producing granulates which contain enzymes and which are suited for feeding animals. The granulates are produced by mixing at least one enzyme with a supporting material and by extruding this mixture. The inventive method is characterized in that the supporting material is firstly plasticized in a screw mixer which is equipped with at least one horizontally arranged screw. Afterwards, the enzyme is introduced into the screw mixer and is processed with the plasticized supporting material to produce a homogeneous material which is then extruded.

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.

The present invention relates to novel phytase-comprising enzyme granules, those particles of which have A) a core which comprises at least one phytase and at least one solid carrier material suitable for feeds, and b) a coating arranged on the core, the cores of the particles or the entire particle, after if appropriate required grinding, on suspension or dissolution in demineralized water at 25° C. giving a pH in the range from 4.5 to 6.5, preferably in the range from 4.6 to 6.0, and particularly preferably from 4.7 to 5.5 and which are suitable as feed additives, and also a method for production thereof. The invention also relates to the use of the phytase-comprising enzyme granules in feed compositions and, in particular, pelleted feed compositions, which are obtainable using the phytase-comprising enzyme granules.

The present invention relates to novel methods for producing coated granulated enzyme-comprising feed additives, to the coated enzyme-comprising granules produced in this manner, and also to feed compositions which are obtainable using the coated granules. This method comprises the following steps: a) Extrusion of an enzyme-comprising dough which, in addition to water, comprises i) 50 to 96.9% by weight of at least one solid carrier material suitable for feed, ii) 0.1 to 20% by weight of at least one water-soluble polymer, iii) 3 to 49.9% by weight of at least one enzyme, the weight fractions of i), ii) and iii) in each case being based on the nonaqueous components of the dough; b) final-processing the extrudate to give raw granules having a water content of no greater than 15% by weight, and c) coating the raw granules with a hydrophobic material selected in an extent of at least 70% by weight, based on the hydrophobic material, from saturated fatty acids, the esters of saturated fatty acids, in particular the mono-, di- and triglycerides of saturated fatty acids, and mixtures thereof.

An x-ray exposure apparatus is freely movable in space without a cable, and allows the electronic production of x-ray images at the bed of a patient. The apparatus includes a cart with an image receiver, such as an amorphous silicon-based solid state detector, to which an image memory on the cart is allocated. Power supply ensues by means of a rechargeable battery that is integrated into the cart.
