Description

A useful model belongs to the grain industry, in particular to the methods of processing wheat into grain products, specifically whole kernel flattened groats.

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 АЗ2ЗИ 1/10, 1985).

Wheat groats are moistened to a humidity of 22-28 95, 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 95. Steamed groats are dehumidified for 30-90 minutes. and carry out additional processing in two stages. At the first stage, groats are moistened to a humidity of 26-32 95 and moistened for 15-45 minutes, in the second - to a humidity of 27-33 9o and moistened for 60-120 minutes. The groats prepared in this way are 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 °C and re-cooled with air at a temperature of 15-20 "C to a temperature that does not exceed the ambient environment by 2-5 "C and a humidity of 21 -27 95. The prepared cereal is flattened into flakes with a thickness of 0.4-0.5 mm. 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.

There is also a well-known method of producing cereal flakes, which involves cleaning the grain from impurities, steaming at a steam pressure of 0.1-0.2 MPa for 3-5 minutes. to reach a humidity of 18-20 95, adding 3-5 95 boiling water, tempering for 0.5-2.0 hours to a humidity of 18-20 95, re-steaming at a steam pressure of 0.1-0.2 MPa for 3-5 min. to a humidity of 25-27 95, drying in a "boiling" layer with air to a humidity of 23-25 95 and cooling to a temperature of 20-25 "С. The grain prepared in this way is subjected to husking, flattened and dried to a humidity of 13-14 Rev. (see patent of the Russian Federation Mo 2236151 A23ZI 1/164, 2004)

This method was chosen by the prototype.

The prototype 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 grain flakes is the long duration of the stage of hydrothermal treatment of grain, which involves steaming the grain twice, 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 useful model is based on the task of developing a method for the production of flattened wheat groats, in which, by 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 by reducing the number of operations, their duration, and to ensure the expansion of the existing range of products and improve 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 in that, unlike the prototype, wheat grain with a moisture content of no more than 15 95 is steamed at a steam pressure of 0.18- 0.20 MPa for 7-10 min., tempered for 30-40 min., dried to a humidity of no more than 14 95, sanded once, moistened with water to a humidity of 25-27 95, dehumidified for 3-4 hours, flattened at an inter-roll gap of 0 ,4-0.5 mm and dried to a moisture content of no more than 14 95.

The method is carried out in the following order. Wheat grain cleaned of impurities, for example, of the "Chornobrova" variety with a moisture content of no more than 15 95, enters operational bunkers. It is controlled for magnetic impurities and enters the stage of hydrothermal treatment, which is carried out according to the structure of hot conditioning. The grain is steamed in a periodic steamer of the PZ type at a steam pressure of 0.18-0.20 MPa for 7-10 minutes. After that, the grain is sent to the bunkers for tempering, which lasts 30-40 minutes. The grain is dried on vertical steam dryers of the VS type to a moisture content of no more than 14 k.

The grain prepared in this way is sent 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. 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 is moistened with water heated to 55-60 "C to a humidity of 25-27 905 and sent to heat-insulated bunkers for dehumidification, which lasts for 3-4 hours. The core is sent to rolling machines for flattening, which is carried out on corrugated rollers at a working gap of 04 -05 mm. The mixture of flattened products is sorted in a grain separator, where flour and small particles of the crushed kernel are removed by passing through a metal woven sieve Mo 1, 2, the flattened kernel is obtained by the riser, which is sent to belt dryers, where drying is carried out to a moisture content of no more than 14 95 After that, flattened wheat groats are obtained. The obtained groats are controlled for the content of metallomagnetic impurities, and then 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 steamed in a batch steamer at a steam pressure of 0.20 MPa for 10 min. After steaming, the grain was tempered in a bunker for 30 minutes. and dried in a dryer to a humidity of 14 95. Grinding was carried out on one system in a peeling-grinding machine, which works according to the principle of intensive abrasion of shells. The mixture of grinding products was passed twice through the aspiration column. The whole polished core was moistened with water to a humidity of 25 96 and sent to a heat-insulated bunker for dehumidification, which lasted 4 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 06 mm. The flattened products were sorted in a grain separator, where flour and small particles of the crushed kernel were removed by passing through a sieve of Mo 1.2, the flattened kernel was obtained by extraction, which was dried in a dryer to a humidity of 14 95, after which the flattened wheat groat was obtained.

As a result of the processing of wheat of the "Chornobrova" variety into flattened groats, the total yield of the finished product was 80 95, by-products and waste (taking into account mechanical losses) - 20 95.
