DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an accessory device for a sausage stuffer for the production of skinless sausages, or the like, having a pipe arrangement adapted for being connected to the filling pipe of the sausage stuffer and comprising heating stations arranged one behind the other.
During production of sausages, in particular barbecue sausages, so-called breakfast sausages, hot dogs, grilling sausages, and the like, the sausage mass is filled into animal or artificial casings by a sausage-stuffing device, using a stuffing horn having a length of approx. 25 to 30 cm. After filling of the casings, the sausage mass is cooked by processing the sausages in a processing oven. Following this step, the sausages are transferred into a water bath. For some sausage types, the cooking process is followed by the so-called peeling or skin-removal process, which mostly takes place in a water bath when the sausages are cut to length. In other cases, peeling of the sausages is effected mechanically, by means of so-called peelers.
The use of artificial casings is expensive, and this is even more critical in the production of skinless sausages as in this case the skin has to be removed by a subsequent peeling process and is then thrown away. Quite apart from the expenses connected with the described process, the operation of spooling the casings on the filling pipe and/or the stuffing horn of the sausage machine is complicated and troublesome and requires skillful operators. Especially in the case of small-caliber sausage types, this operation requires a high labor input. The operation of spooling the casing on the filling pipe of the sausage machine, the separate scalding process following the stuffing operation, and finally the additional removal of the peel-off casings have for their consequence that approximately 6 to 8 operators must be employed per sausage machine if the latter is to be operated continuously. This situation is even aggravated by the fact that due to these different processes, the observation of the prescribed sanitary regulations is extraordinarily difficult and/or connected with correspondingly high expenses.
From DD 246 699 A1 an accessory device has become known which is designed for connection to the filling pipe of the stuffing machine which normally receives the casings for filling in the sausage emulsion. In the case of this known accessory device, skinless sausages are to be produced by loading the sausage emulsion into a pipe provided with tubular electrodes which are separated from each other by electrically non-conductive pipe sections. The electrodes are supplied with a low-frequency current which flows from one electrode to the neighboring electrode, through the sausage mass contained in the non-conductive pipe section, thereby heating up the sausage emulsion in that pipe section. It is said that when the non-conductive pipe sections with the electrodes are multiplied in a convenient manner, the sausage mass will finally be well-done all through. However, the electric field extending between the electrodes, along the pipe section, will be distributed over the pipe cross-section with a sufficient degree of uniformity only if the length of the pipe section is relatively big, compared with the pipe diameter. In addition, it is a consequence of the skin effect that the flow lines are displaced to the periphery of the cross-section and the selected current density may not be too high. Finally, the conductivity varies as the sausage emulsion gets more and more solid. In addition, the conductivity of the sausage emulsion will rarely be exactly uniform over the full cross-section of the pipe, due to the different mass components, and the current always finds its way from electrode to electrode along the path of least resistance. Consequently, it is not possible with the aid of the described arrangement to achieve the desired uniform distribution of the current density and, accordingly, uniform heating of the mass over the whole cross-section. If, however, this known arrangement is given a le
