- FIG. 10 shows the result of the two dose modifications, namely on the one hand the dose increase on the facing side and on the other hand the dose reduction according to FIG. 9 through the element 4, so that the dose profile 21 in FIG. 10 results, and one located in the dose target range 18 Local / dose curve 21 of a dose strip 17 wound around the Brutei 42 using a filter element / electron shield 4 irradiated with electrons 31 and a brooding egg 42 underneath.
- FIG. 11 shows a schematic representation of a second device 30 according to the invention with hatching eggs 43 held by rollers 47, 48 on a transport system 5 equipped with rollers 47, 48 with an optional final recontamination unit 13 for the treated hatching eggs 43.
- the second device 30 for treatment of hatching eggs of poultry with electron beams 31 for sterilization of the calcareous shell 22 thus contains according to FIG. 1 1 the following units and lines, which largely correspond to the elements of the first device 20:
- rollers 47, 48 or with a system of several roller pairs 47, 48,
- the central control unit 1 is in Fig. 1 and Fig. 1 1 also at least with a line 54 or with cable lines with
- FIG. 12 shows a cross section perpendicular to the pole axis of the brooding egg 43 and FIG. 13 shows a longitudinal section horizontally in the direction of the polar axis of the brooder 43.
- a brooding round 43 in the form of a round body is guided through an electron beam 14 a uniform and all-round irradiation of the surface is achieved.
- a rotational movement is performed while the Brutei 43 is in the beam path 14.
- Rotation changes the speed of points on the surface of the hatching boat 43, depending on the distance of the surface point due to the rotation. This rate is used directly in formula (I):
- Istrahi an electron beam current
- FIG. 14 is a schematic black box representation of a combined, third inventive device 50 with held hatching eggs 42 in zero-degree position according to the pivoting device upstream first device 20 and in a pivoted, for example, 180-degree position according to one of Swivel device locally downstream first device 201 shown with the same structure as the device 20 on a transport system 5 with the pivoting device 49.
- the eggs lying in the pivoting device 49 the eggs lying in zero-degree position hatching eggs 42 are pivoted in an angular-degree position, for example, 180-degree position and then on the opposite 180 ° side is irradiated with electrons 31 by means of the downstream first device 201.
- the eggs 42 can be pivoted to another predetermined angle.
- the method for treating hatching eggs 42, 43 with an electron beam bundle 14 for sterilizing the calcareous shells 22 of the hatching eggs 42, 43 comprises the following steps:
- Electron beam wherein as a result of each rolled by a predetermined angle of rotation Bruteies 43, the calcareous shell 22 is irradiated comprehensively, or
- the eggs 42, 43 of poultry to be treated with electron beams 31 may be table eggs, industrial eggs and preferably hatching eggs.
- the invention thus also relates to a method and a device for shadowing (according to FIG. 8, FIG. 9, FIG. 10) or for the local reduction of the electron dose in the treatment of hatching eggs 42, 43 by means of accelerated electrons 31 for the purpose of sterilization (killing or passivating microorganisms such as bacteria, viruses and fungi).
- the electron filter / the electron aperture 4 or a barrier element of adapted geometry and adapted material between the electron beam source 2 and the treated Brutei 42, 43 is positioned.
- the local electron dose increase caused by the egg shape can be reduced at the areas of the treated ice 42, 43 located closest to the electron beam source 2 become. This allows an increase in the electron energy.
- the average range of the accelerated electrons 31 increases, so that even further away eiareles can be exposed to sufficiently high electron doses. As a result, this leads to a reduction in the dose gradient between the nearest and farthest calcareous shell areas 16-17 to the electron beam source 2.
- oxygen atoms 35 present in the microporous calcareous shell 22 are ionized and thus generate ozone which, for example, penetrates into the nucleic acid core of viruses through the protein coat and damages the RNA thereof. This will make them inactive or dying.
