Definitions
- the invention relates to a method for creating the tangled shape of a pretzel from a previously straight, stretched strand of dough with the aid of a machine in order to reduce the production costs of the pretzels.
- pretzels can be pressed into the desired pretzel shape using a two-part mold.
- pretzels consist of a dough that is not sprayable, but must be rolled into a strand of dough, from which the pretzels must then be looped.
- the desired internal consistency of this baked good is only achieved by the strand of dough rolled in its cross-sectional representation.
- this method is disadvantageous because the thinner ends of the strand of dough are particularly difficult to handle and, moreover, a method which works by gripping the ends of the strand of dough is made more difficult, if only because the dough has rolled out to form a strand of dough this strand of dough can have a relatively widely differing length, so that the gripping positions are only possible after the previous measurement of the strand of dough.
- DE-OS 3 900 950 it is known from DE-OS 3 900 950 to take up the middle part of the dough strand by means of a receiving molded part, which has the shape of a scoop, and to rotate this scoop through 360 ° to achieve the middle knot, with the scoop held roughly horizontal and then to put the strand of dough down again.
- the disadvantage of this method is that asymmetrical pretzels are formed due to the looping movement, in which the middle part of the dough strand is in a horizontal plane, since one end of the dough strand is pulled more than the other, which in extreme cases can even be subjected to pressure.
- This creates not only different thicknesses, but also different lengths of dough strand ends during the slinging process, so that these pretzels are not only asymmetrical in their design, but also the compressed end of the dough strand may no longer be put down after laying
- the middle area is covered so that no pretzel occurs at all.
- the strand of dough can be taken up by the receiving molded part in that it - in the vertical tilted state - from above and essentially - - * ⁇ ? - - is moved vertically against the middle part of the dough strand, and this middle part of the dough strand by appropriate gripping members against an opposing gripping member or a firmly on
- Receiving molding is pivoted up about a horizontal axis until a vertical position of the receiving molding is reached again.
- Underside of the then approximately horizontally lying receiving molded part is to be arranged on the later upper side of the receiving molded part.
- the receiving molding has a circumferential surface over at least 180 °, which corresponds to the later inner contour of the central part of the pretzel, so that when the receiving molding is tilted up, the side regions adjoining the central region of the strand of dough hang vertically from this peripheral surface, while the ends of the strand of dough lie on the ground and are still in the hold-downs, which between the
- the part of the dough strand which is arranged around the receiving molded part is made by performing a movement of the
- Shaped molded part carried out transversely to the longitudinal extent of the original strand of dough.
- the rear part of the molded part is moved to the rear so that the sides of the looped pretzel come to lie at the desired location over the ends of the dough strands.
- the female molded part is still arranged slightly obliquely, the rear region of the female molded part almost reaching the ground, but the front region being higher.
- a subsequent transverse movement in the opposite direction loosens the part of the dough strand lying around the rear region of the shaped receptacle, possibly supported by active elements, and is on the Filed underground.
- the empty receiving part is then again moved in the transverse direction towards the central region of the original strand of dough, so that the shaped receiving part is located both above the crossing points of the ends of the partial strand and above the middle node.
- By lowering the approximately horizontally held shaped receptacle, its outer regions then interact with the crossing points of the ends of the dough strand with the areas above the dough strand, for which purpose pressing surfaces which can be extended outwards are arranged on the shaped receptacle.
- a central pressing surface for pressing the middle knot of the pretzel can be provided in the center of the molded part.
- the receiving molded part is preferably also moved in the transverse direction during the initial tilting up in such a way that the dough strand itself does not have to move in the transverse direction, but rather the taken-up central part of the dough strand only moves in moved up a vertical plane.
- Another possibility for problem-free receiving of the middle part of the dough strand by the receiving molded part is that the receiving molded part has less during the recording - ⁇ ⁇ - strong curvature of its outer contour and in
- Dough strands are approximated by the molded receptacle, which is then stretched at least in the middle, and the dough strand is held tight.
- Such a slinging machine is preferably located above the transpoort belt on which the stretched, raw dough strands are transported in the direction of their longitudinal extent. If there is such a strand of dough in the working area of the slinging machine, the belt is stopped and the pretzel is looped and placed on the same conveyor belt. Then the next strand of dough is transported by means of a clock circuit.
- a turning device can be provided after the slinging machine in front of the
- the receiving molded part can be pivoted by a small 180 °, preferably 270 °, arranged above the dough strand, horizontally and parallel to the dough strand, both vertical positions of the molded part, that is, with its symmetrical or underneath approachable must be.
- This swivel axis must be variable in order to be able to bring the receiving molded part both into contact with the dough strand and to
- this horizontal pivot axis is accommodated in a carrier head for the shaped receptacle.
- This carrier head can be varied in height by means of corresponding intermediate elements in relation to a stationary base frame, and can also be pivoted about a vertical axis and can be moved in the transverse direction to the strand of dough.
- the carrier head is mounted about an essentially perpendicular axis with respect to a head base arranged above it, and this head base can be changed both in the transverse direction of the strand of dough and in height with respect to a fixed machine base frame.
- connection of the head base to the base frame can preferably take place via a swivel lever, which is on the one hand on the base frame and on the other hand on the - 7-
- Head base is pivotally attached and is essentially horizontal, but can be tilted around the bearing in the base frame.
- the head base is not only adjustable in height, but also in its position to be taken in the transverse direction with respect to the dough strand, in which the head base and thus also the vertical pivot axis between the head base and the carrier head are pivoted about the bearing point in the pivot lever and thus out the vertical can be deflected.
- the receptacle molding itself must be movable either by 180 ° or by 270 ° about its horizontal pivot axis, depending on whether the receptacle molding is more in the for receiving the dough strand
- the entire device is preferably arranged above the conveyor belt for the dough strands, so that in the region of the plane of the dough strands there is no spatial obstruction for other units.
- the looping machine also includes movable hold-downs for the strand of dough in the processing position, with which the ends of the dough
- a measuring and positioning device which also has a subsequent, central alignment of the in usually allows dough strand lying on the conveyor belt.
- the length of the dough strands is not always the same, because due to the rolling of the dough strands at the same
- the amount of dough may result in different lengths of the dough strand due to not always the same contact pressure.
- Pretzels that the length of the protruding ends in a finished pretzel is not always the same, but depends on the length of the original dough strand and the skill of the pretzel wringer etc.
- the protrusion cannot be dimensioned too tight, because then with undersized dough strands u. U. in the case of a shaped tablet with an unchangeable circumference, the ends of the dough strand would no longer be connected to the overlap regions.
- the peripheral surface of the female molded part does not have an unchangeable shape, but can be changed during the handling process, for example by this peripheral surface consisting of a flexible material.
- this circumferential surface can be subjected to a less rigidly curved, ideally completely straight, straight contour. - II - ⁇ itzen, and thus a complete approximation of this
- the peripheral surface of the molded receiving part is bent together to form the final contour, which then corresponds to the inner contour of the later pretzel.
- this circumferential contour in the final state could then - after previous measurement of the initial length of the strand of dough - be adapted to the initial length of this strand of dough, so that an optimally shaped pretzel with an optimal shape is always independent of the length of the strand of dough
- a further optimization of the workflow could also be achieved in that the grippers, with which the strand of dough is held firmly on the receiving molded part, are not always moved into the same closed position, but rather the end position of the closed position from the previous measurement of the thickness of the dough strand depends in this area.
- FIG. 2 shows a front view according to FIG. 1;
- FIG. 4 is a front view according to FIG. 3,
- FIG. 6 is a frontal view of FIG. 5,
- FIG. 7 is a side view in which the rear region of the looped pretzel is being put down
- FIG. 8 is a front view according to FIG. 7,
- FIG. 10 is a frontal view according to FIG. 9,
- Fig. 12 is a plan view of the finished looped, stored pretzel with the molded molded part and pressed thereon - / 3-
- FIG. 13 shows a representation similar to FIG. 1, but when the strand of dough is picked up by essentially horizontal approximation.
- FIG. 1 shows a side view of the receiving molded part 3, which in the vertical position, with its front region 6 downward, was moved vertically towards the dough strand and the gripper 12 was closed to grip the dough strand.
- the middle part 4 of the dough strand 1 is between a support edge 13 running along the rear edge of the receiving molded part, which extends in the plane of the receiving molded part, and two grippers 12, which can be better seen in the front view of FIG. 2 , held.
- the carrier head 16 around the lower end of which the receiving molded part 3 can be pivoted backwards about the horizontal axis 15, is in an approximately vertical position, and thus also the vertical axis of rotation 7 between the carrier head 16 and the head base arranged above it 20th
- the entire unit must be lowered, which is done in that the lever 21 connecting the head base 20 to the base frame 24 is pivoted obliquely downward around the bearing point in the base frame 24.
- Carrier head 16 are preferably carried out by means of pneumatic conversion, for which purpose a ring supply of the compressed air takes place in the vertical axis of rotation 7 in the interior of the axis of rotation, so that the
- Carrier head 16 together with the shaped receptacle 3 does not have to be rotated back 360 ° into the starting position after carrying out the looping movement, but a continuous further rotation is possible. This reduces idle times and increases the machine's output.
- FIG. 13 shows a solution in which the receiving molded part 3 for receiving the dough strand 1 is not moved vertically from above, but rather approximately horizontally with the inclined receiving molded part toward the dough strand 1.
- the front region 6 of the receiving molded part 3 approaches the dough strand 1 horizontally so that it is then on the underside of the
- the receiving molded part has an outer peripheral surface 8 corresponding to the inner contour of the subsequent pretzel. All around and above ⁇ e ⁇ en over this Umfan ⁇ sflache 8 is the support edge 13 which protects the Tei ⁇ stran ⁇ with a vertical position of the molded part from falling to the side, and with a horizontal position the arrangement of the support edge 13 on the underside supports the Tei ⁇ stran ⁇ 1.
- the receiving molded part 3 After picking up the strand of dough - as indicated in FIG. 1 by the arcuate arrow - the receiving molded part 3 is pivoted backwards by approximately 180 °, while at the same time the support head 16 is pulled up slightly by means of the pivot lever 21 in order to grip the central part 4 of the Lift dough strand 1 off the surface.
- the head base 20 can be pivoted so that the shaped receptacle 3 and thus its pivot axis 15 move forward, that is, away from the vertical plane passing through the dough strand 1.
- a coordination of this vertical movement with the tilting movement about the pivot axis 15 is sought, which as a result has the effect that the gripped central part 4 of the dough strand 1 does not undergo a transverse movement, but only a lifting movement vertically upwards. This favors a problem-free application of the dough strand around the peripheral surface 8 of the shaped receptacle.
- the lateral parts of the dough strand 1 hang freely down from the side regions 10 of the molded part and extend outward through the hold-down device 17 by means of a deflection. From this position, the receiving molded part 3 is raised further until it has reached at least the height as shown in FIG. 3, and then the support head 16 with the receiving molded part 3 and the dough strand 1 about the vertical axis 7 arranged above the dough strand 12 Is rotated 360 ° so that the parts of the dough strand 1 hanging on both sides of the receiving molded part 3 are entangled, such as can be seen in Fig. 5 and 6. Even after the actual looping movement has been carried out, the ends of the dough strand 1 may still be below the hold-down devices 17, as can also be seen in FIG. 6.
- a first step as shown in the side view of FIG. 7, the strand of dough is therefore deposited from the rear area of the molded part.
- Dough strand 1 is moved forward, so that the ends of the dough strand come to lie at the desired location under the transition between the middle part 4 and the outer region 11 of the pretzel.
- the front area of the pretzel 2, that is to say on the left in FIG. 7, is now to be detached from the shaped receiving part 3.
- the molded part 3 moves slightly linearly again after reaching the base right, i.e. towards the starting position of the dough strand.
- the strand of dough is slightly stretched in its side region 11, so that the region in the rear in FIG. 7 no longer lies against the peripheral surface 8 of the shaped receptacle.
- the receiving molded part 3 is tilted with its front region 6 downwards and with its rear region upwards, but no more dough strand adheres to the rear region of the receiving molded part 3.
- the front area with the central part 4 of the dough strand 1 the latter reaches the ground, usually the conveyor belt, and remains there after the gripping members 12 have been released.
- Another possibility is to pull the molded receptacle 3 obliquely upwards and forwards, ie to the left in FIG. 9, from the position shown in FIG. 9 in order to bring the molded receptacle 3 completely out of contact with the dough strand 1. Then the receptacle molding, after it is brought into a horizontal position, is moved to the right again, that is to the front, until it has reached the position - / S- position according to FIG. 12 in the top view of the shaped
- the outer contour of the shaped receptacle 3 is only shown in an interrupted manner.
- Operation in the plane of the receiving molded part 3 can be folded down so as not to impede the previous processing steps.
- End regions can also serve lateral pressing plates 26 projecting laterally beyond the receiving molded part on the underside of the receiving molded part 3 - in this position - which must of course be designed to be extendable.
- Press plates can also be fulfilled by the gripping members 12 provided at these points, provided that they are sufficiently flat and have a flat outer contour.
