An invention for automatic feeding out of dishes from pot and pans

Abstract: The invention refers to a device for automatic output of stews, and the like dishes from large cooking-utensil which dishes do not stand pumping without being detoriated in consistency. The device comprises an output tube (11) immerseable in the vessel (11) in which tube a slidable piston (3) is received, which piston is displaceable in up and downward direction by means of a driving device. The piston is hollow with lower and upper apertures, whereby the lower the aperture is closeable by means of a valve (18) arranged such that by downward motion of the piston be open and by the ascendant motion be closed, so that the piston by its ascendant motion carries substance through the output tube (11).

Description: Technical field Device for automatic output of stews, and the like dishes from large cooking-utensil The background of the invention Preparation of institutional kitchen food takes place in great food processing vessel with volumes of up to several hundred litre. Liquid and similar to pasta dishes as soup, gruel, porridge, mash etc. can be pumped out from the vessel while dishes which contain solid constituent for example stews of different types, do not stand such a inclement treatment without an appreciable deterioration of the consistency being obtained. The purpose of the invention and most important characteristics: The purpose with the invention is to provide an output device for the later type of dishes, which device is kind to the dish and not in appreciable extent impairs its consistency. According to the invention this has been achieved by an output tube immerseable in a vessel, a slidable piston being received in said tube said piston being displaceable in an up and down direction by means of a driving device, the piston being hollow and provided with apertures at its lower and upper ends, whereby the lower aperture is closeable by means of a valve arranged in such a way that in the downward motion said piston is open and in the ascendant motion it is closed, so that the piston in its ascendant motion carries substance to be contained in the vessel through the output tube. The subject-matter of dependent claim 2 concerns further particular embodiments. Description of the drawings An embodiment of the invention is shown in the enclosed drawing, where Fig. 1 is a vertical section through a device according to the invention located in a vessel. Fig. 2 is a section according to the line II-II in fig. 1. Description of an embodiment The device, which is placed in a cooking-utensil 10 includes a tube 11, which contains an output nozzle 12 which is bent to an essentially horisontal direction. In the vertical part of the tube 11 13 is slidably received, a piston, which by means of a motor 14 arranged outside the vessel 10 can be conveyed in a reciprocating motion. The piston 13 is hollow as a tube and is by means of a clamp 15 connected to the piston rod 16. The lower opening of the piston is closeable by means of a valve including a pair of flaps 18 turnable about hinges 17. These are preferably spring loaded so that they at the ascendant motion of the piston fall downwards and close the lower opening of the piston, whereby the piston brings substance up towards the output nozzle 12. At the downward motion of the piston 13 the flaps are opened by the counter pressure from the substance in the vessel. The invention is naturally not limited to the embodiment shown but a number of modifications are possible within the scope of the concept of the invention as claimed.

Claims: Device for automatic output of stews, and the like dishes from large cooking-utensil, characterized by an output tube (11) immerseable in a vessel (10), a slidable piston (3) being received in said tube, said piston being displaceable in an up and down direction by means of a driving device, the piston being hollow and provided with apertures at its lower and upper ends, whereby the lower aperture is closeable by means of a valve (18) arranged in such a way that in the downward motion said piston is open and in the ascendant motion it is closed, so that the piston in its ascendant motion carries substance to be contained in the vessel (10) through the output tube (11). Device according to claim 1, characterized by that the valve (18) includes a pair of spring loaded turnable flaps which are turned upwards by the counter pressure of the substance in the vessel (11) against the spring action in the downward motion of the piston (13), said flaps in the ascendant motion falling downwards and closing the lower opening of the piston (11).
