Abstract: The food spraying device useful in the large bakeries, comprises a spraying means, a conveyer (2) exhibiting two parallel belts (4, 5), a spraying nozzle intended above the conveyer, guidance rails (40, 41, 46), and housing segments (95, 106). The spraying nozzle is freely positionable above the conveyer by a cross slide (39) and is supplied with the spray by a flexible feed line (62). The device is formed as a self-supporting bridge with an upper carrier frame, to which two guidance rails of the cross slide are attached. The food spraying device useful in the large bakeries, comprises a spraying means, a conveyer (2) exhibiting two parallel belts (4, 5), a spraying nozzle intended above the conveyer, guidance rails (40, 41, 46), and housing segments (95, 106). The spraying nozzle is freely positionable above the conveyer by a cross slide (39) and is supplied with the spray by a flexible feed line (62). The device is formed as a self-supporting bridge with an upper carrier frame, to which two guidance rails of the cross slide are attached. The two guidance rails are arranged parallel to the conveyer direction of the conveyer and exterior to their clearance. A third guidance rail is movably arranged parallel to the conveyer direction. The spraying nozzle is movable at a slide along the third guidance rail running in a transverse manner to the conveyer direction. The ends of the third guidance rail are provided with slides, which are guided along the rails arranged respectively above them. The third guidance rail exhibits a terminal extension, which runs transversely to the guidance rail supporting the third guidance rail, and is provided with a protruding attachment below and parallel to the guidance rail supporting it. The free ends of the terminal extension and the protruding attachment are connected by a reinforcing bracing. The extension and the reinforcing bracing carry a drive device of the slide. Another drive device is attached at the center of the third guidance rail. The drive devices exhibit an electric motor, which drives a circulating hauling unit that carries the slide or the guidance rail with it. The conveyer is surrounded by a collecting trough at the bottom. A carrier for the food rests on the parallel belts. The food is moved on a conveyer while passing through the device. The spraying means is stored in a flexible bag that is arranged in a compressible container and is attached to a connecting sleeve for the flexible feed line by a spreading device. The flexible feed line is connected by quickly-changeable connections to a container-fixed connecting sleeve, a connecting sleeve of the spreading device and/or a nozzle arrangement. The nozzle arrangement exhibits a valve that is regulated by an electric motor or electromagnets or a cylinder and a centrally-divided housing, which is held together by a quickly- changeable connection. A first housing segment exhibits an interior cross-section that is reduced in comparison to that of a second housing segment. A collar is formed through the reduction of the cross-section. A guiding piece exhibiting a threaded hole supports itself against the shoulder. A plunger, which exhibits a partially formed exterior thread and a closing element at an end, is swivellably-mounted in the threaded hole. The guiding piece is held at the other end by an expander that supports itself against a housing bottom. The spraying nozzle is admitted into a housing bottom of the nozzle arrangement and is attached by a quickly-changeable connection to a discharge component of the nozzle arrangement. The adjustment direction of the closing element lies on an axis that is in line with that of the sprayed jet.
