DESCRIPTION:
BRIEF SUMMARY
SPECIFICATION
Field of the Invention
The invention relates to a process for suspending chains of sausages in loops, in which successive hooks that rotate in an essentially horizontal plane grasp, at a transfer point, a twist point positioned roughly vertically there and located between two sections of the chain of sausages and convey it out of the vertical plane passing through the transfer point, and also an appropriate device for performing said process.
Background of the Invention
Sausages are normally produced by sausage filling machines in the form of long portioned sausage chains. Two adjacent sausages are divided from one another by a twist point. After a chain of sausages has been arranged in loops, a smoking skewer or stick is pushed through the loops. Sausages having natural skins are previously wound around the smoking stick in loop form. The chain of sausages is then deposited in this form onto a smoking truck, which is subsequently conveyed into a smoke house. During smoking it is crucial that the sausages do not touch, otherwise light patches would remain at the points of contact, which would not only have an unfavourable effect on the external appearance of the sausages but would also reduce their keeping qualities.
Mechanical suspension devices (e.g. DE-P 27 44 350.1) are known, with which a chain of sausages can be automatically hung in loops after it has left a filling machine. In this known suspension device hooks are attached to an endless chain that rotates essentially in a horizontal plane. A feed mechanism for the chain of sausages is also provided, the outlet of which opens in the space above the plane of transport and vertically above an area scanned by a reception area for the hooks. A switch scanning the twist points of the chain of sausages is located in the area of movement of the sausage chain above the transport plane and is connected to a control mechanism for driving the endless chain and/or the feed mechanism. The free end regions of the hooks are constructed as V or U shapes in two planes.
However the known suspension devices are only suitable for sausages which are produced with artificial skins. This is because these sausages have certain advantageous properties for their further processing which are not displayed by sausages produced with natural skins: their diameter and their length are to a great extent constant, they have either no curvature at all or, when the skin is pretreated in a suitable manner, regular curvature, good sliding properties and low sensitivity to mechanical stresses.
Natural skin sausages on the other hand have varying diameters and lengths. It is crucial that they normally have their natural curvature and that this curvature varies. Furthermore their sliding properties are poor and their sensitivity to mechanical stresses is relatively great.
The previously known suspension devices are not in practice suitable for sausages made with natural skins because of the variability of their properties. In particular the fact that the suspended sausages touch slightly because of their curvature can not be avoided, with the result that these touching parts were insufficiently smoked or not smoked at all and consequently both the storage life is reduced and also an optically unsatisfactory result was obtained with respect to the external appearance because of the lighter parts.
SUMMARY OF THE INVENTION
The object of the invention is therefore to provide a process and also a device for hanging sausage chains in loops, in which sausages having natural skins can also be processed and can be positioned for transfer onto a smoking skewer.
In a process for suspending sausage chains in loops, in which successive hooks that rotate in an essentially horizontal transport plane grasp, at a transfer point, a twist point positioned roughly vertically there and located between two sections of the chain of sausages and convey it, optionally cyclically, out of the vertical plane passing through the transfer point, the distance between the advancing twist point of each
