SI23256A - Procedure of uninterrupted thermal treatment of dough and device to carry out the procedure - Google Patents

Abstract

The submitted invention relates to a procedure of uninterrupted thermal treatment of dough, particularly liquid dough, preferentially dough for pancakes, in which liquid dough is scooped from a container (3) and transported to a dispensing vessel (6) which distributes it over a heating cylinder (1). Baking of dough on the first side then follows on the said heating cylinder (1), after which dough, baked on the first side, is stripped from the first heating cylinder (1) and transferred on the second heating cylinder (2). Baking of dough is then carried out still on its second side and finally, the fully baked dough is stripped from the second heating cylinder (2).

Continuous heat treatment of the dough and apparatus for carrying out the process

The present invention relates to a process for continuous heat treatment of a dough, in particular a liquid dough, and preferably a pancake dough, said dough being at least one flexible and heat-emitting heating element, and a device for carrying out said method.

The aforementioned devices for continuous heat treatment of dough, especially pancakes, are known. For example, the publication of the international application no. WO 03043424 Al disclosed solution comprising anti-self moving and heat conducting bands. In doing so, the dough, to a limited extent, for example in the form of a flat disk, is applied to the bottom strip, where said dough is heated from the bottom, while simultaneously moving under the upper strip, which said dough is heated from the top. Furthermore, from the publication of international application no. WO 8702866 Al known solution comprising a heated roller on which dough is applied and which bakes only one side of the pancake. The pancake is then removed with a scraper from the cylinder and placed on a heated strip and rolled.

The disadvantage of these solutions is the fact that they only involve baking individual pancakes. The baking is done either first on one side and then transferred to a flat surface where it is baked on the other side, or simultaneously baked on both sides with two heated plates. This results in the trapping of air in the dough and, consequently, its uncontrolled eruption through the already sealed surface, which is reflected in the non-aesthetic surface. Outbursts of trapped air through the lateral surface can also occur, thereby polluting the appliance with dough and uneven lateral pancake edges.

It is an object of the present invention to provide a process of continuous heat treatment of a dough, in particular a liquid dough, preferably a pancake dough, which will eliminate the disadvantages of known solutions.

A further task is to create a device for continuous heat treatment of the dough, especially the liquid dough, preferably the pancake dough.

The process of continuous heat treatment of the dough according to the invention is based on the continuous supply of liquid dough from the container to the dispenser, by which said dough is evenly distributed over the entire length of the upper heating cylinder. In doing so, said upper heating cylinder rotates at such a speed that said baking dough is exactly baked when said upper heating cylinder is rotated about half a turn.

In the area of the lowest point of the upper heating cylinder is arranged the first scraper, which from the upper heating cylinder protects from the first side the baked dough, which then falls in the area of the upper point on the lower heating cylinder, on which the dough is baked on the other side. The dough is completely baked when the said lower cylinder is rotated about half a turn. In the region of the lowest point of said lower heating roller there is a second scraper disposed of from the lower heating roller which eliminates completely baked dough. It then drops to a conveyor device arranged in the area just below said lower cylinder, and then said completely baked dough in the form of a continuous strip is either cut or arbitrarily curled and stored in a container.

The invention is hereinafter further described and described with reference to the accompanying drawing, which schematically shows a device for continuous thermal treatment of the dough according to the invention.

The continuous heat treatment apparatus of the dough according to the invention consists of a pair of horizontally spaced, parallel to one another and horizontal and vertical spaced apart cylinders 1, 2 intended for heat treatment of the dough to be baked. Said heating rollers 1, 2, which are counter-rotating about their respective longitudinal axis, are designed to be movable and offset, both horizontally and vertically. The surfaces of said heating cylinders 1, 2, which are either smooth or optionally embossed, are heated in a manner known and not shown in detail, for example, by means of gas, electricity and the like.

Said device further comprises a container of liquid dough, into which a mixing agent 4 extends, occasionally stirring said dough and preventing it from solidifying or hardening. the collapse of it. Said liquid dough is fed from said container 3 by means of a pump 5 in a manner known per se to a dispensing vessel 6 arranged in the immediate vicinity of the area of the upper end of the first, in the case of the upper cylinder 1 here, preferably. 1. For a more even distribution of said dough, especially when denser dough is used, said dispenser 6 is provided with a vibrating device 7 which, either with occasional or continuous shaking, makes it easier and faster to distribute the dough over the heating cylinder 1.

Each heating cylinder 1, 2 is provided with a scraper 8, 9 in the region of its lowest end, which preferably extends over the entire length of the respective cylinder 1.2. Further, each lubricant cylinder 1, 2 is optionally fitted with a lubricating device 10, 11 which, if necessary, is applied to the outer surface of the respective heating cylinder 1, 2, for example an oil which prevents the dough from adhering to the surface of the heating cylinder. To ensure the proper temperature of the heating cylinders, a temperature gauge 13, 14 is provided for each heating cylinder, for example, a contactless thermometer, which controls the rotation of the cylinders, the flow of dough and the cutting or other device for finishing the product by means of a control device 15.

It is further contemplated according to the invention that in the area under the second heating cylinder 2, in the present case it is the lower heating cylinder 2, the transport device 16 is disposed, on which it is deposited and by which the baked dough is transported away from the heating cylinders 1, 2 Further, in the extension of said conveyor device 16 is arranged either a cutting apparatus for baking dough running from said second heating cylinder 2 or a container 17 for storing said baked dough.

The operation of the continuous heat treatment of the dough according to the invention is based on the continuous supply of a relatively liquid dough from the container 3 by means of a pump 4, which supplies said dough to said dispensing vessel 6. By means of the latter, said dough is evenly distributed over the entire length of the upper heating cylinder 1 , the invention being preferably provided for the dough to continually run on said upper heating cylinder in the area before the upper point A thereof. Said upper heating cylinder 1 rotates at such a speed that said baked dough is exactly baked when said heating cylinder 1 rotates about half a turn.

In the region of the lowest point B of the heating cylinder 1, said scraper 8 is arranged, which from the heating cylinder 1 eliminates the baked dough from the first side, and then falls in the area of the upper point C onto said lower heating cylinder 2. This bakes the dough further after on the other hand, so that it is fully baked when said lower cylinder 2 is rotated about half a turn. In the region of the lowest point D of the said lower cylinder

2 is a said scraper 9 disposed of a completely baked dough falling from the heating roller 2 falling on the transport device 16 arranged in the area just below said heating roller 2. Thereafter, said fully baked dough in the form of a continuous strip is either cut or in any manner rolls and saves in said container 17.
