Abstract

 A device for rolling dough pieces containing cylindrical and barrel-shaped rolls mounted alternately on two parallel endless chains with the possibility of free rotation, and a conveyor belt for workpieces placed under endless chains, characterized in that the rolls are combined and consist of solid cylindrical and barrel-shaped cases on which the elastic elements with cylindrical working surfaces are fixedly fixed.

Description

The utility model relates to the baking industry for producing thin dough pieces, including those with filling, and can be used in catering and other food industries, for example, for making puff pastry dough.

A device is known with an elastic element in the form of a foam pad supported by a web with adjustable web tension. This device improves the shape of the dough pieces formed by rolling between the conveyor belt and a fixed plate containing an elastic element (See AS USSR No. 152440, class A21C 3/09, published in 1963)

However, this device does not allow to form thin layers of dough, including with various fillings.

Also known is a device for forming thin dough pieces by rolling, containing solid (rigid) working cylindrical and barrel-shaped rolls, a conveyor belt for workpieces with drive and tension drums (See AS USSR No. 1243669, class A21C 3/02, published on July 15, 86 in B.I. No. 26, a prototype.).

The disadvantages of this design are that the hard working surface of the roll cannot fully differentially monitor the local pressure changes of the rolled dough pieces with a filling, especially containing coarse components of animal origin in the form of minced meat or vegetable components in the form of poppy seeds, sesame seeds, vegetable pastes and others components. Coarse-grained components randomly, depending on their distribution over the area of the dough piece, affect the local rheological parameters of the molded piece with the filling during rolling. Therefore, rigid forming rolls with an unchanged geometry (the radius of the rolls does not change from the local pressure under them) also limits performance, especially for dough pieces with a filling containing coarse components.

The problem to which the invention is directed is to increase the molding speed and uniformly distribute the filling over the area and height inside the thin dough pieces.

This is achieved by the fact that in a device for rolling dough pieces containing cylindrical and barrel-shaped rolls mounted alternately on two parallel endless chains with the possibility of free rotation, and a conveyor belt for workpieces placed under endless chains, according to a utility model, the rolls are combined and consist of from solid cylindrical and barrel-shaped cases on which elastic elements with cylindrical working surfaces are fixedly fixed.

The essence of the utility model is illustrated by drawings.

Figure 1 presents a diagram of the proposed device with combined rolling rollers, figure 2 is a diagram of the combined rolls.

The device comprises an inclined belt conveyor 1 with a drive 2 and a tension 3 reels.

Above the conveyor there are endless chains 4 mounted on the drive 5 and tension 6 sprockets. The protrusions 7 are fixed on the chains 4, with the axles 8 mounted on them, on which the combined rollers 9 and 10 are mounted with free rotation. The rollers 9 and 10 contain respectively rigid (rigid) cylindrical and barrel-shaped housings on which the elastic elements 11 and 12 with cylindrical work surfaces. Rolls with different housing configurations are mounted alternately on the chains. All rolls 9 and 10 on both sides have rigid cylindrical endings 13 with a diameter larger than the roll diameter by an amount determining the double thickness of the dough piece, minus the double deformation of the elastic elements of the rolls, which provides elastic deformation of the dough piece.

The device operates as follows.

By starting electric drives (not shown in the drawing), the carrier chains 4 and the conveyor 1 are driven. Being in the upper part of the device, the rollers 9 and 10 are moved by chains without rotation relative to their axes. This occurs until the rolls 9 and 10 come in contact with their cylindrical ends 13 with the conveyor 1, after which the rolls begin to rotate counterclockwise when the conveyor belt 1 moves from left to right.

Ready to roll out the dough pieces with the filling 14 are placed on the moving belt of the conveyor 1. Getting under the rolls 9 and 10, the dough piece with the filling is rolled into the dough piece 15, the size of which, consisting of the upper and lower layers of the dough and the inner layer of the filling, at the exit from the conveyor reaches the desired thickness of 16, a height of about 5 mm and a diameter of 250-350 mm.

Rolls 10 (figure 2), having a solid barrel-shaped body, press on the dough piece with its middle part with greater force. Therefore, the rolling of the dough piece with the filling occurs not only in the direction of movement of the conveyor belt 1, but simultaneously along the axis of the combined roll 10 with a solid barrel-shaped body. Getting under the roll 9, the test piece is calibrated by thickness, reaching equal thickness over the entire area.

Multiple contact interaction of the elastic elements 11 and 12 of the combined rolls 9 and 10 exclude the tendency of local destruction of the rolled blanks, evenly distributes the filling inside the test case of the product according to its area and height, improves the quality of molding products and productivity. This reduces the duration of obtaining a dough piece with a filling of uniform thickness, with the exception of additional operations necessary to correct the uneven distribution of the filling layer over the entire area of the product.

The proposed device allows you to effectively mold better dough pieces without filling, which have not only elastic, but also significant plastic properties.

Thus, the use of a utility model, in the design of which combined rolls consisting of solid cylindrical and barrel-shaped housings on which elastic elements with cylindrical working surfaces are fixedly mounted, are used as working bodies of the rolling device;

- increase device performance;

- expand the scope of the device for rolling in the production of various products of food production enterprises;

- improve the quality of filling the filling of dough pieces;

- expand the technological capabilities of the device for the production of a wide range of products.
