Abstract

FIELD: food industry.

SUBSTANCE: one supplies dough in a gap between one pair of rollers rotating in opposite directions and obtains a thick dough ribbon at the gap outlet. After that, one imparts a constant shape to the ribbon in its cross section along the whole thick ribbon length between the rollers pairs. The obtained thick ribbon is passed through a gap of the next pair of rollers rotating in opposite directions; a thin ribbon with decreased cross section is obtained. In the zone between roller pairs gaps one performs arbitrary ribbon sagging, measures the ribbon sagging value and, depending on such value, decreases or increases the rate of the first rollers pair rotation. Between the two roller pairs gaps, one imparts an inclined position to the ribbon while the ribbon sagging (h) is performed within the range of (0.2-0.8)H, where H is the centre-to-centre distance between the first and the second roller pairs.

EFFECT: invention allows to enhance the dough rolling quality and rate.

Description

The invention relates to the food industry, in particular to the production of products from rolled dough.

A known method of rolling a test strip, providing for the movement of the test mass between the rolling elements, providing a calibration of its thickness by acting on sections limited by the width of the strip, the rolling is carried out by shifting the effect of the rolling elements sequentially along the direction of movement of the test strip and at least one of its longitudinal edges, at the same time, a single exposure is performed at each site, which ensures obtaining a predetermined thickness size of the rolled test moose (RU 2004127599 A, 02.20.1994).

In this method, they act by rolling elements on the middle part of the test strip, followed by a symmetrical (relative to the middle part) bias of the action in two directions to both longitudinal edges of the test strip.

In this method, each subsequent action of the test strip, the action of the rolling elements is shifted relative to the previous effect by an amount smaller than the size of the area of the impact of the previous rolling elements.

In the specified method, the limits of the area of influence of the rolling elements on one part carry out the action with uniform force, and on the other part, on the side of the longitudinal edge of the test strip, to which the offset is carried out - with the force of the impact decreasing to the said edge.

In this method, the test mass is moved between two rows of successively installed rolling elements made with calibrating sections that have an effect on the test mass.

In this method, when rolling, a microvibration effect is applied to the test mass and / or to the rolled test strip.

A known method of rolling dough by rotating towards each other rollers, involving the passage of the test between a pair of upper rolls and between a pair of lower rolls installed under them, and the rolls of each pair are mounted with a given gap between themselves and rotate in the direction of the dough feed down, characterized in that the upper rolls with a variable speed, and the lower rolls with a constant speed, when applying the test from the gap between the upper rolls to the gap between the lower rolls, measure when the dough has entered the gap between the lower rolls , the angle of rotation of each lower roll from the point where the test surface comes into contact with the outer part of the lower roll to a given point, compare this angle with a given range of angles and adjust the speed of the upper rolls to provide a value for the specified angle in a given range of angles such in which the dough, having a uniform volume along its length, was unloaded from the gap between the lower rolls without destroying the fabric structure of the dough (RU 2020824 C1, А21С 3/02, 10/15/1994).

There is a second variant of the method according to patent RU 2020824 C1, in which the dough passes between a pair of upper rolls and between a pair of lower rolls installed under them, the rolls of each pair are mounted with a given gap between each other and rotate in the direction of the dough feed down, and the upper rolls are rotated with a variable the speed, and the lower ones at a constant speed, when applying the test from the gap between the upper rollers to the gap between the lower rollers, measure the thickness of the test before feeding it into the gap between the lower rollers, compare the specified thickness with the specified a wide range of thicknesses and regulate the rotation frequency of the upper rolls to ensure the value of the specified thickness in a given thickness range such that a dough having a uniform volume along its length can be unloaded from the gap between the lower rolls without destroying the fabric structure of the dough.

Of the known closest technical solutions to the technical solution presented in this description is a device for rolling out the dough and getting a dough tape out of it, containing a frame on which an upper pair of rollers having a drive to rotate them in opposite directions, as well as a lower pair of rollers having another drive for their rotation in opposite directions, between each pair of rollers an adjustable gap is formed, and the device is equipped with a control unit electrically connected to the drive of rotation in a pair of rollers and position sensors of the test tape, a pendulum is fixed between the upper and lower pairs of rollers on the frame by means of an axis with a support roller mounted on it, which serves to track the position of the test tape and stabilize its working position when it moves and deviates from the specified position, while a sensor for tensioning the test tape located on one side of the pendulum and a sensor for sagging the test tape located on the side of the pendulum are fixed on the frame, the pendulum being made n in the form of a frame with sides restricting the movement of the test tape in its transverse direction, and in its lower part there is a protrusion designed to interact with the position sensors of the test tape, in addition, the lower pair of rollers is shifted to one side relative to the upper pair of rollers, and the width of each roller of the lower pair is 2-10 mm wider than the width of each roller of the upper pair (RU 128457 U1, 05.27.2013).

Common features of the claimed and well-known technical solutions is that first the dough is fed into the gap between one pair of rolls rotating in opposite directions and a thick dough tape is obtained at the exit of the gap, after which the resulting thick tape is passed through the gap of the next pair of rolls rotating in opposite directions and get a thin tape with a reduced cross section of a thin tape.

A significant drawback of the known technical solution is that its use does not allow to increase the speed of rolling the dough within the required limits, since in case of exceeding these limits the quality of the resulting tape decreases, breaks in the test tape, clogging of the device with dough and, as a result, the device stops and requires it cleansing.

The technical result of the invention is to improve the quality and productivity of rolling dough.

The technical result is obtained by the method of rolling dough, which consists in the fact that the dough is first fed into the gap between one pair of rolls rotating in opposite directions and a thick dough tape is obtained at the exit of the gap, after which the tape is given a constant shape in its cross section over the entire length of the thick tape and then the resulting thick tape is passed through the gap of the next pair of rolls rotating in opposite directions, to obtain a thin tape with a reduced cross section of a thin tape, and in the zone between By the clearances of the pairs of rolls, the sagging of the tape is arbitrary sagging within (0.2-0.8) N, where N is the center-to-center distance between the first and second pairs of rolls, the amount of sagging of the tape is measured and, depending on this value, the rotation speed of the first pair is reduced or increased rolls, and between the specified clearance of the rolls of the tape give an inclined position.

In FIG. 1 shows a diagram of a device for rolling dough, explaining the method; in FIG. 2 is a schematic diagram of an expansion explaining the method; in FIG. 3- section AA in FIG. one.

The device for implementing the method comprises a first pair of rolls rotating from the drive in opposite directions, which is formed by rolls 1 (Fig. 1) located on the geometric axis 2 so that there is a gap between the rolls 1. The device contains a second pair rotating from the drive in opposite directions rolls, which is formed by rolls 4 with a gap 5 between them. The second pair of rolls is located below the first pair of rolls and is shifted to the side so that zone 6 is formed between the gaps 3 and 5 of the pairs of rolls. In this zone, arbitrary h sagging of the test thick tape 7 is made. FIG. Figure 1 shows the two extreme positions of the test thick tape that the tape may occupy during the rolling process of the dough. This tape occupies different positions between the two extreme (minimum and maximum) sagging h of the thick tape 7 shown in FIG. one.

Zone 6 is vertically limited by the shortest distance H between the gaps 3 and 5. Such a distance in this method is located on the perpendicular restored from the symmetry point of the gap 3 and extending towards the lower gap 5. The gap 5 is shifted in the horizontal direction from the indicated perpendicular by the amount selected depending on the sagging of the test tape between the gaps. In zone 6, the test thick tape 7 along its entire length along the length has a constant cross section (Fig. 3).

It should be noted that the sagging h of the test thick tape 7 in this method is the distance between line 8 (Fig. 1), passing through the axis of symmetry of each gap, and the point 9 located farthest from line 8, located in the middle of the tape 7 along its thickness.

The method is as follows. The dough 10 is fed into the gap 3 between one pair of rolls 1 and 2 rotating in opposite directions, and a conditionally thick test tape 7 is obtained at the exit from the gap 3 (Fig. 2). A thick tape 7 is given a former (not shown) with a constant shape in its cross section along the entire length of the tape. The resulting thick tape 7 is passed through the gap 5 of the next pair of rolls 4 rotating in opposite directions and a thin tape 11 with a reduced cross section is obtained. In zone 6, between the gaps 3 and 5 of the pairs of rolls, the tape sags arbitrarily by h. Measure the amount of sagging tape h and, depending on this value, reduce or increase the speed of rotation of the first pair of rolls 1. In this case, the sagging tape h is carried out in the range (0.2-0.8) N, where N is the center-to-center distance between the first and second pairs rolls.

Select the speed of rotation of each pair of rolls during the rolling process of the dough and the rotation speed of the pairs of rolls control the amount of sagging h and the quality of the thin tape 11. Depending on the quality of the thin tape, the speed of rolling the dough and the performance of the device for rolling the dough are controlled.

In comparison with the known methods of rolling dough, the use of this method has significantly improved the productivity of rolling dough and the quality of rolling.
