Definitions
- UV-C-reflective inner wall portions of the housing no, or in any case fewer, UV-C light sources have to be positioned next to, along and/or under the conveying device because the UV-C-reflective inner wall portions reflect the UV-C light from the one or more UV-C light sources so as to disinfect the product on the conveying device as if one or more UV-C light sources were positioned on the side next to, along and/or under the conveying device.
- inner wall portions of these side walls may contribute substantially to maximum UV-C reflection for an effective disinfection process of leaf- shaped products in the device.
- the at least one portion of the inner wall portions of the housing that are directed toward the conveying device, in particular the side walls thereof, may be designed to maximize UV-C reflection in the direction of the product on the conveying device when in operation.
- the at least one portion of the inner wall portions of the housing that are directed toward the conveying device, in particular the side walls of the housing may be configured so as to be at least partially curved and/or have at least one kink so that, by virtue of the design of the inner wall portions, UV-C light is maximally reflected toward the leaf-shaped products on a conveying surface of the conveying device.
- At least the first conveying device section may be arranged at an angle a with respect to a horizontal surface so that the end of the first conveying device section is arranged higher than a beginning of the first conveying device section, and preferably the angle a is between 10-30 degrees, even more preferably between 15-20 degrees.
- the end of the first conveying device section of the conveying device sections may be arranged 20-70 cm higher with respect to the base surface than the beginning of the second conveying device section, and preferably 30-60 cm higher. Tests show that such a height is particularly suitable for rotating the leaf shaped products as they fall and for achieving effective mixing so that the surface of each leaf-shaped product can be disinfected by UV-C light effectively and efficiently.
- Fig. 2B schematically shows a front view of the device shown in figure
- Figures 2A, 2B show a pattern of the UV-C light sources 113 that is similar to the pattern shown for the elongate UV-C light sources 13.
- the elongate UV-C light sources 13 may, for example, be known fluorescent tubes that emit UV-C. However, it is also possible for the elongate UV-C light sources 13 to be formed by UV-C LEDs.
- the UV-C light sources 113 may likewise be UV-C LEDs.
- the moving mechanisms it is possible to prevent, in the case of leaf-shaped products lying on the conveying surface in bulk with many leaves potentially lying on top of one another, resulting in substantial shading, that not only the uppermost leaves are treated with (reflected) UV-C light.
- the leaf-shaped products are thrown upward with a certain frequency so that the (reflected) UV-C light may treat all sides of the leaf-shaped products during the upward movement.
- the leaf shaped products may be turned over by these movements produced by the moving mechanisms 20A-D; 420A,B so that both the upper side and underside of the product to be treated may be illuminated in turn by UV-C light.
