Abstract

The proposed technical solution relates to the food industry, mainly to the production of extruded products from grain raw materials. The technical result of the claimed utility model is to improve the organoleptic properties of the product, leveling and increasing the shape of bread, thereby expanding the product range. The problem is achieved in that the extruder matrix contains three sequentially located cavities with passage holes and a die with a through rectangular hole. An inventive step of the claimed utility model is that in the first cavity the passage hole is made increased by 20%, the hole in the second cavity is made reduced by 30%, the configuration of the chamber of the third cavity is made with a gradual narrowing to the slot hole in front of the die, and the through hole of the die is made larger twice as long.

Description

The proposed technical solution relates to the food industry, mainly to the production of extruded products from grain raw materials.

A device for manufacturing a food extruded product is known, comprising an extruder with a die and a rotatable forming head mounted therein, characterized in that the transition conical surface and the transition cylindrical surface of the forming head are located outside the die of the matrix. (See p. RU 2137372, Cl. A 21 C 11/16, publ. 09/20/99.)

The disadvantage of this device is the small degree of grinding of the grain mixture and bringing its constituent particles to readiness.

The closest technical solution to the proposed one is a device for manufacturing an extruded food product, comprising a housing, a loading hopper with a vibrodoser, a matrix and a tensioner, characterized in that the transition alignment cavity, the transition diaphragm with a hole, and the adaptive cavity with a slotted diaphragm are successively made in the matrix and a die with a through hole. (See p. RU 2223682, Cl. A 23 P 1/12; publ. 02.20.2004)

The disadvantage of this technical solution is that the finished product in the form of flat bread comes with torn edges, the taste of which leaves much to be desired, since the taste of burnt grain is felt. Bread rolls are not porous enough.

The technical result of the claimed utility model is to improve the organoleptic properties of the product, leveling and increasing the shape of bread, thereby expanding the product range.

The problem is achieved in that the extruder matrix contains three sequentially located cavities with passage holes and a die with a through rectangular hole. An inventive step of the claimed utility model is that in the first cavity the passage hole is made increased by 20%, the hole in the second cavity is made reduced by 30%, the configuration of the chamber of the third cavity is made with a gradual narrowing to the slot hole in front of the die, and the through hole of the die is made larger twice as long.

Reducing the bore in the second cavity creates more pressure on the product, which increases the porosity of the bread. An increase in the aperture by 20%, the implementation of the chamber of the third cavity with a gradual narrowing, as well as an increase in the length of the passage

dies twice - all this, in general, improves the conditions for the formation of the shape of bread and, accordingly, the quality of the final product. The dimensions of the modified passage holes are selected experimentally.

The device matrix of the extruder is illustrated by drawings.

Figure 2 is a cross section of the first cavity

Figure 3 is a cross section of a third cavity

In the housing 1 of the matrix of the extruder is installed with the possibility of rotation of the millstone 2, in which the first 3 of the three consecutive cavities with through holes is made. The cavity chamber 3 is cylindrical in shape. The diameter of the through hole 4 of the cavity 3 is increased by 20%. Next, in the direction of the product in the matrix, there is a second cavity 5 with a passage hole 6, which, in general, is reduced by 30%, and a third cavity 7 with a slot hole 8, the size of which is left unchanged. The configuration of the chamber of the third cavity is made with a gradual narrowing to the slit hole 8. All cavities 3, 5, 7 with passage holes 4, 6, 8 are aligned with each other. Behind them is a die 9 with a through rectangular hole 10, the passage length of which is doubled.

The device operates as follows. The grain mixture during operation of the extruder enters the matrix body 1 on the working surface of millstone 2. Here, the grain mixture is mixed, compacted and heated during grinding and compression. Then, the milled grain mixture is squeezed out through the passage hole 4 of the first cavity 3. Then, the grain mixture passes through all of the following holes 6, 8 of successively located cavities 5, 7, enters through the die hole 9 into the die 9 and fills a rectangular horizontally elongated through-hole in the form of a soft mass after extrusion hole 10 of the die, from which the finished product emerges in the form of flat rectangular bread rolls, enlarged, increased porosity and with smooth edges.
