Description

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

There is a known method for the production of fast-boiling products from wheat groats, which includes moistening, dehumidification, steaming, tempering, repeated two-time moistening and dehumidification, cooling, drying, re-cooling, flattening (A.S.

USSR Mo. 1338833 IPC A2ZI. 1/10, 1985).

Wheat groats are moistened to a moisture content of 22-28 °C, dehumidified 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 additional processing is carried out in two stages. At the first stage, the groats are moistened to a humidity of 26-32 9o and moistened for 15-45 minutes, at the second stage - to a humidity of 27-33 9o and moistened for 60-120 minutes. The cereal prepared in this way is subjected to preliminary cooling to a temperature that does not exceed the surrounding environment by 2-5 "C and a humidity of 25-31 95. The cooling agent (air) has a temperature of 15-20"C. After that, the groats are dried in a "fluidized bed" with a drying agent temperature of 100 C to a humidity of 22-28 9°C and re-cooled with air at a temperature of 15-20 "C to a temperature that does not exceed the ambient environment by 2-57 and a humidity of 21-27 95 The prepared cereal is flattened into flakes 0.4-0.5 mm thick. This technological operation is carried out on machines with smooth rollers. The flakes are dried at an air temperature of 40-60 "C 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 quick-boiling products from wheat groats is the long duration of the stage of hydrothermal 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 the implementation of this process in plants of low productivity.

The closest analogue is the 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 min until the humidity reaches 18-20 95, adding 3-5595 of boiling water, tempering for 0.5-2.0 h. to a humidity of 18-20 96, repeated steaming at a steam pressure of 0.1-0.2 MPa for 3-5 minutes to a humidity of 25-27 96, drying in a "boiling" layer with air to a humidity of 23-25 5905 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. (Russian Patent Mo 2236151 А2ЗИ 1/164, 2004)

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

The disadvantage of the technological process of the production of cereal flakes is the long duration of the stage of hydrothermal treatment of grain, which includes two steaming of the 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 the implementation of this process at factories of low productivity.

The basis of a useful model is the task of developing a method for the production of flattened groats from wheat, in which by soaking, steaming and drying the grain before processing, one-time grinding, one-time moistening and dehumidification of the polished kernel, as well as the use of wheat of a certain variety, to ensure the simplification of the technological process due to 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 in the method of production of flattened wheat groats, which involves cleaning the grain from impurities, moistening, dehumidification, flattening and drying because, according to a useful model, wheat grain with a moisture content of no more than 1595 is soaked in water heated to 55-60 "С 150-190 min, dehumidify for 30-55 min, steam at a steam pressure of 0.14-0.16 MPa for 4-7 min, dry to a humidity of no more than 14 95, moisten the core with water heated to 55-60"C to a humidity of 18 -2095, moistened for 1.5-2.5 hours, flattened with an inter-roll gap of 0.3-0.5 mm and dried to a moisture content of no more than 14 95.

The method is carried out as follows.

Wheat grain cleaned of impurities, for example, of the "Chornobrova" variety with a moisture content of no more than 1595, enters operational bunkers. It is controlled for magnetic impurities and enters the first stage of hydrothermal treatment. The grain is sent to special vats with water heated to 55-60 "C for soaking, which lasts for 150-190 minutes. After that, the grain is dehumidified in special bunkers for 30-55 minutes, removing excess moisture from the grain at this stage. At the second stage the grain is steamed in intermittent steamers of the PZ type at an excess pressure of 0.14-0.16 MPa for 4-7 minutes. After steaming, the grain is sent to a dryer, where it is dried to a humidity of no more than 14 95. The grain prepared in this way is sent to grinding, which is carried out on one 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. An increase in the wheel speed of grinding machines will contribute to a more intensive removal of the surface layers of the grain, which will lead to an increase in the number of by-products in the form of crushed kernel and flour particles, 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 enters the second stage of hydrothermal treatment, which is carried out according to the structure of cold conditioning. The polished core is moistened with water heated to 55-60"C to a humidity of 18-2095 and sent to heat-insulated bunkers for dehumidification, which lasts for 1.5-2.5 hours. The core prepared in this way is sent to rolling machines for flattening, which is carried out on corrugated rollers with a working gap of 0.3-0.5 mm. The mixture of flattening products is sorted in a grain spreader where

Flour and small particles of the crushed kernel are removed from the metal woven sieve Mo 1.2, the flattened kernel is obtained in the east, which is sent to belt dryers where they are dried to a humidity of no more than 14 95, after which they obtain quick-cooking flattened wheat groats. The resulting cereal is controlled for the content of metallomagnetic impurities, after which it is 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 the stage of hydrothermal treatment. The grain was soaked in water heated to 60 "С for 150 min. After that, it was dehumidified in a special hopper with a perforated lower surface for 55 min, removing excess moisture from the grain at this stage. At the second stage, the grain was steamed in a batch steamer at an excess pressure of 0, 14 MPa for 7 min. After steaming, the grain was dried to a moisture content of 14 95 and sent to grinding, which was carried out on one system in a peeling-grinding machine, which works on the principle of intensive shell abrasion. The mixture of grinding products was passed twice through an aspiration column and sent to the second hydrothermal treatment stage.

The core was moistened with water heated to 55"C to a humidity of 1895 and sent to a heat-insulated hopper for dehumidification, which lasted 2.5 hours. The core prepared in this way entered the rolling machine. Flattening was carried out on corrugated rollers with a working gap of 0.4 mm. Flattening products they were sorted in a grain separator, where flour and small particles of the crushed kernel were removed by passing through the Mo 1, 2 sieves, the flattened kernel was obtained in the east, which was dried in a dryer to a humidity of 14 95, after which the quick-cooking wheat flattened groat was obtained.

As a result of the processing of wheat of the "Chornobrova" variety into flat groats, the total yield of the finished product was 77 95, by-products and waste (taking into account mechanical losses) -
