Description

A useful model belongs to the cereal industry, in particular to methods of processing wheat into cereal products, specifically flattened cereals.

There is a known method of production of products that boil quickly from wheat groats, which involves moistening, dehumidification, steaming, tempering, repeated two-time moistening and dehumidification, cooling, drying, re-cooling, flattening (see copyright certificate of the USSR Mo 1338833 МПК А2ЗИ 1/10, 1985).

Wheat groats are moistened to a humidity of 22-28 96, moistened for 50-70 minutes. and steamed at a steam pressure of 0.1 MPa for 30-90 seconds. In the course of this technological operation, the humidity of the groats increases to 25-31 96. Steamed groats are dehumidified for 30-90 minutes. and carry out additional processing in two stages. At the first stage, the groats are moistened to a humidity of 26-32 9o and moistened for 15-45 min., at the second stage - to a humidity of 27-33 96 and moistened for 60-120 min. The groats prepared in this way are subjected to preliminary cooling to a temperature that does not exceed the surrounding environment by 2-57C and a humidity of 25-31 Ob.

The cooling agent (air) has a temperature of 15-20 "С. After that, the cereal is dried in a "fluidized bed" with a temperature of the drying agent of 100 "С to a humidity of 22-28 °C and re-cooled with air at a temperature of 15-20 "С to a temperature that does not exceed the surrounding environment by 2-5 "C and humidity 21-27 95. The prepared cereal is flattened into a 0.4-0.5 mm thick flake. This technological operation is carried out on machines with smooth rollers.

Flakes are dried at an air temperature of 40-60 "С for 4-6 minutes. The total yield of flakes is up to 95 95.

The analogue and the claimed useful model have the following operations in common: - humidification; - dehumidification; - flattening

The disadvantage of the technological process for the production of products that boil quickly from wheat groats is the long duration of the stage of water-heat treatment of grain, which includes three-time moistening, dehumidification, steaming, drying and two-time cooling of the groats, which requires significant production areas to accommodate the appropriate technological equipment, bunkers for dehumidification and tempering and causes difficulties in implementation

From this process in factories of low productivity.

There is also a known method of producing cereal flakes, which includes cleaning the grain from impurities, steaming at a steam pressure of 0.1-0.2 MPa for 3-5 minutes. until the humidity reaches 18-20 95, adding 3-5 95 boiling water, tempering for 0.5-2.0 hours. to a humidity of 18-2095, re-steaming at a steam pressure of 0.1-0.2 MPa for 3-5 minutes. to a humidity of 25-27 °C, drying in a "boiling" layer with air to a humidity of 23-25 95 °C and cooling to a temperature of 20-25 °C. The grain prepared in this way is subjected to husking, flattened and dried to a humidity of 13-14 95. (see Russian patent No. 2236151 А2ЗИ 1/164, 2004).This method was chosen as the closest analogue.

The closest analogue and the claimed useful model have the following common operations: - grain cleaning from impurities; - hydration; - dehumidification; - flattening; - drying

The disadvantage of the method of production of grain flakes is the long duration of the stage of water-heat treatment of grain, which includes twice steaming of grain, moistening with boiling water, drying, cooling, which requires significant production areas to accommodate the appropriate technological equipment, bunkers for dehumidification and tempering, drying equipment and causes difficulties in implementing this process at factories of low productivity.

The useful model is based on the task of developing a method for the production of flattened grains from wheat, in which, by excluding the stage of water-heat treatment of grain, husking, inclusion of one-time grinding, the stage of fractionation, one-time moistening and dehumidification of the polished kernel, as well as the use of wheat of a certain grade, to ensure simplifying the technological process by reducing the number of operations, their duration, and ensuring the expansion of the existing range of products and improving their quality.

The task is solved by the fact that the method of production of flattened grains from wheat, which includes cleaning the grain from impurities, moistening, dehumidification, flattening and drying, according to a useful model, wheat grain with a moisture content of no more than 1595 is ground once, because it is fractionated, while leaving the sieve 2.4x20 mm are moistened with water heated to 55-60 "С to a humidity of 24-25 95, dehumidified for 4-6 hours, the passage of the sieve 2.4x20 mm and the exit from the sieve Mo 1, 2 are moistened with water heated to 55-60 "С to a humidity of 21-23 95, dehumidify for 2-3 hours, both fractions are flattened with an inter-roll gap of 0.3-0.4 mm and dried to a humidity of no more than 14 95.

The method is carried out in the following order. Wheat grain cleaned of impurities, such as the "Chornobrova" variety, with a moisture content of no more than 1595, enters operational bunkers.

It is controlled for magnetic impurities and goes to grinding, which is carried out on the same system. For grinding, peeling and grinding machines are used, which work according to the principle of intensive abrasion of shells. The circular speed of the disks is set to 16-18 m/s.

A decrease in the circular speed of the discs will lead to insufficient removal of the surface layers of grain when processing grain on one system, which will accordingly cause the need to increase the number of systems. Increasing the circular speed of grinding will contribute to a more intense removal of the surface layers of the grain, which will lead to an increase in the number of by-products in the form of particles of crushed kernel and flour, while reducing the yield of the whole kernel and finished products. An increase in the yield of by-products will cause the need to expand the stage of sorting grinding products due to the installation of additional grain dispersers or sieve-air separators and aspiration columns.

After grinding, the mixture is passed through two systems of air separators or aspiration columns. The polished core is sent for sorting to grain separators, where it is separated into two fractions. Passing through 2.4x20 mm sieves, a coarse fraction is obtained, passing through 2.4x20 mm sieves and passing through metal woven sieves Mo 1, 2 - small fraction. At the next stages of the technological process, the processing of the obtained fractions is carried out in parallel by two streams.

The ground core of the coarse fraction is moistened with water heated to 55-60 "С to a humidity of 24-25 95 and sent to heat-insulated bunkers for dehumidification, which lasts for 4-6 hours.

The fine fraction is moistened with water heated to 55-60 "С to a humidity of 21-23 95 and sent to heat-insulated bunkers for dehumidification, which lasts for 2-3 hours. The core of both fractions prepared in this way is sent to rolling machines for flattening, which is carried out on corrugated rollers with a working gap of 0.3-0.4 mm. The mixture of flattened products is sorted in a grain spreader, where flour and small particles of the crushed kernel are extracted by passing through a metal woven sieve Mo 1, 2, flattened groats are obtained by rising, which

It is sent to belt dryers, where it is dried to a humidity of no more than 14 95.

During the processing of the coarse fraction, flattened wheat groats Me 1 are obtained, and the small fraction - flattened wheat groats Me 2. The obtained flattened groats are controlled for the content of metallomagnetic impurities, after which they are sent to packaging or to bunkers for finished products.

Example.

We got flattened groats. For this purpose, wheat grain of the "Chornobrova" variety, with an initial moisture content of 13.5 95 and a weight of 2000 g, cleaned of impurities, was weighed on automatic scales and sent to grinding, which was carried out on one system in a dehusking-grinding machine, which works on the principle of intensive shell abrasion . The mixture of grinding products was passed twice through the aspiration column and sent to the grain disperser for sorting. Passing through 2.4x20 mm sieves, coarse fraction was obtained, passing through 2.4x20 mm sieves and passing through metal woven sieves Mo 1, 2 - small fraction. The core of the coarse fraction was moistened with water heated to 55-60 "С to a humidity of 25 95 and dehumidified in a heat-insulated bunker for 6 hours. The core of the fine fraction was moistened with water heated to 55-60 "С to a humidity of 23 95 and dehumidified in a heat-insulated bunker for 3 hours. The core prepared in this way was fed into the rolling mill. Flattening was carried out on corrugated rollers with a working gap of 0.3 mm. The flattened products were sorted in a grain separator, where flour and small particles of the crushed kernel were removed by passing through Mo 1, 2 sieves, and flattened groats were obtained through the sieve, which was dried in a dryer to a moisture content of 14 95. When processing the coarse fraction, flattened wheat groat Mo 1 was obtained, small - flattened wheat groats Mo 2.

As a result of the processing of wheat of the "Chornobrova" variety into flattened cereals, the total yield of the finished product was 74 95, by-products and waste (taking into account mechanical losses) - 26 9.
