Description

70362

The present invention relates to an apparatus for applying a piece of dough. The device comprises a conveyor belt for transferring the dough pieces and a pressing member forming the dough pieces arranged above it.

Devices of the type mentioned above are, for example, so-called rolling machines, in which a piece or strip of dough is exposed to either a longitudinal or transverse rolling action. The main disadvantage of these rolling mills is that they tend to tear the dough during processing, as a result of which the moisture content of the dough decreases considerably in the subsequent processing stages, mainly in the raising and baking stages. In addition, the toughness of the dough is lost, which is due to the fact that in rolling, the processing takes place in only one direction.

The object of the device according to the present invention is to obviate the above-mentioned drawbacks provided by a device characterized in that the pressing member consists of a pressing plate known per se. is arranged to rotate at a circumferential speed substantially corresponding to the speed of the conveyor and in such a direction that the press plate substantially follows the speed of the conveyor during the pressing step and that the press plate is on the outlet side of the device less than the conveyor side.

Other features of the invention will be apparent from the appended claims.

In the following, the invention will be explained in more detail with reference to the accompanying drawing, in which FIG. 1 shows an example of a device according to the invention in longitudinal section and FIG. 2 is a top view of the device.

2 70362

The device according to the invention comprises a conveyor belt 1 for transferring dough pieces and a press member 2 arranged above it. The press member consists of an actual press plate 2, both ends of at a circumferential speed which substantially corresponds to the speed of the conveyor belt 1 and is oriented such that the pressing plate 2 essentially follows the speed of the conveyor belt 1 during the pressing step.

The distance of each crankshaft or eccentric shaft 3 to the conveyor belt 1 is adjustable by its own eccentric adjuster 4, which adjusters act directly on the support arms of the pressing member. The distance is preferably adjusted so that the untreated piece of dough fits between the press plate 2 and the conveyor belt 1 when the press plate 2 is in its central position, i.e. when both crankshafts 3 have rotated about 90 ° counterclockwise in their upper position. When the discharge end of the pressing plate 2 is at a shorter distance from the conveyor belt 1 than its end, the pressing effect on the dough piece increases for each pressing step as the dough piece moves with the conveyor belt 1. Due to the eccentric movement of the pressing plate 2, the pressing plate 2 moves laterally during the pressing step at approximately the same speed as the conveyor belt 1, whereby the piece of dough is not exposed to the shearing effect at all.

The lower surface of the press plate 2 is suitably provided with lenticular protrusions 2a on the feed-end half of the device and longitudinal, preferably somewhat cross-arranged protrusions 2b on the opposite half. The purpose of the protrusions 2a, 2b is to compress the dough from many different directions in the manner of a human hand, with the lenticular protrusions corresponding to the palms and the longitudinal protrusions corresponding to the fingers.

In order to prevent the dough from sticking to the protrusions 2a, 2b of the press plate 2, the press plate 2 is surrounded by an endless fabric strip 5 arranged to move around the press plate 3 70362, for example by this eccentric movement. In order to allow the piece of dough to move and press against the protrusions, the fabric strip 5 is mounted quite loosely around the press plate 2. A flour separator 6 is preferably mounted above the pressure plate 2, which extends over the entire width of the pressure plate 2. The flour spreader 6 is used to sprinkle flour on the fabric strip 5 to prevent the dough from sticking. The pressing member is preferably coated with a cover 9 in which the flour separator 6 is suitably mounted.

The movements of the pressing plate 2 and the conveyor belt 1 are preferably provided by means of two electric motors 7, 8. The electric motor 7r which drives the crankshafts or eccentric shafts 3 is preferably provided with a speed variator and the second electric motor 8 which drives the conveyor belt 1 is provided with a reduction gear 15 in order to achieve a suitable rotational speed. The transmission of these engines 7 resp. 8 and the corresponding drive members 1, 2, 3 to be used are preferably arranged via chains 11 and 12.

When the piece of dough is fed to the conveyor belt 1, this is arranged to move the piece of dough in the device according to Fig. 1 to the right below the press plate 2 where it becomes pressed by the eccentric movement of the press plate 2. During the first pressing steps, the dough piece is treated with the part of the pressing plate 2 provided with 25 lenticular protrusions 2a, whereby the pressing plate 2 moves to the right at approximately the same speed as the conveyor 1 during each pressing step and returns to its initial position during the return movement. When the outlet end of the press plate 2 is closer to the conveyor belt 1 than its inlet end 30 which can be easily adjusted by means of adjustment plates 10 connected to the eccentric controllers 4, the pressing effect of the press plate on the dough piece increases from one pressing step to another. As the piece of dough moves further to the right, it becomes pressed by the part of the press plate provided with longitudinal protrusions 2b, after which the pre-treated piece of dough 4 70362 moves from the conveyor belt 1 to the next processing station.

It is obvious that the various details of the device can vary considerably within the scope of the invention, so that the drawing is only intended to explain the principles of the invention.
