Description

The useful model belongs to the cereal industry, in particular to methods of processing whole grain barley into cereal products, specifically barley flour.

There is a known method of producing barley flour with a yield of 7095, which includes grain cleaning from impurities, three-fold peeling in upholstery machines, two-fold peeling on peelers that ensure intensive abrasion of the shells, grinding on six shredding systems (dr. s.) and six grinding systems ( r. s.), processing of stairs from 5 and 6 dr. s. on brush machines, obtaining flour by sieving on sieves with a hole size of 315-280 microns (Shvetsova, I.A., Production of flour from grain and seeds of grain and non-traditional cultures / I.A.

Shvetsova, E.N. Gavrilova, I.V. Kuzmenkova. M.: Tsniyitsy khleboproduktov, 1994, 26 p.)

The analogue and the claimed useful model have the following common operations: - grain cleaning from impurities; - grinding; - sorting of grinding products.

The disadvantage of the technological process for the production of barley flour is the long technological process (the need to carry out three-time peeling of grain in upholstery machines, two-time peeling with the use of machines of the AT-ZSHN type), the presence of a complex grinding stage, which involves 6 shredding and grinding systems, the use of brush machines, which requires significant production areas for the placement of appropriate technological equipment and causes difficulties in implementing this process at factories of low productivity.

The closest to the claimed useful model is the method of production of barley flour, which includes cleaning the grain from impurities, hydrothermal treatment, grinding and sorting (see RF patent Mo 2245192 IPC VO2S 9/04, 2005).

Barley grain is cleaned of impurities, moistened to a humidity of 21-22 95 and dehumidified for 18-20 hours. The grain prepared in this way is roasted at a temperature of 210-220" for 2-3 minutes, while the moisture content of the grain is reduced to 8-9 95. After roasting, grinding is carried out in a rolling machine. Grinding products are sorted by size in a separator. Sieve output 0 4, 2, obtained during sorting, is returned for re-grinding.

The passage of sieve 2 4.2 and the exit of the Mo 080 sieve are directed to aspiration, after which it is ground on three shredding and three grinding systems to flour, which is obtained when sifting through the passage of a kapron sieve Mo 27. The yield of flour is 69-72 95.

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; - hydrothermal treatment; - grinding; - sorting of grinding products.

However, the known method involves a long duration and complexity of the technological process: carrying out the stage of hydrothermal treatment, involves humidification and dehumidification for 18-20 hours, roasting in special machines, which requires significant production areas for placing bunkers and appropriate technological equipment, which causes difficulties in implementation of this process at factories of low productivity.

The basis of a useful model is the task of developing a method of production of barley flour, in which by replacing grain moistening with soaking, eliminating roasting, introducing grinding, shortening the grinding stage, processing grinding products in an entoleator, as well as using whole grain barley of a certain grade, simplification of the technological process is ensured by reducing the number of operations and their duration.

The task is solved by the fact that in the method of producing barley flour, which includes grain cleaning from impurities, hydrothermal treatment, grinding and sorting of grinding products, according to a useful model, bare barley grain with a moisture content of no more than 15 95 is soaked in heated to 55-60 "With water for 180-240 min., dehumidify for 20-30 min., dry to a moisture content of no more than 14 95, grind on two systems and grind on four systems, while grinding products are additionally processed in an entoleitor.

The method is carried out in the following order. Cleaned from impurities, bare grain barley grain, for example, of the "Gladiator" variety, with a moisture content of no more than 15 95, is sent to special tanks with water heated to 55-60 "C for soaking, which lasts for 180-240 minutes. After that, the grain is moistened in in special bunkers for 20-30 minutes, removing excess moisture from the grain at this stage. The grain prepared in this way is dried on vertical steam dryers to a moisture content of no more than 14 95 and sent to grinding. This stage is carried out in grinding machines that work on the principle intensive abrasion of shells, type ZShN with the use of two systems. The circular speed of the disks is set at 18-20 m/s. A decrease in the circular speed of the disks will lead to insufficient removal of the surface layers of the grain during processing on two systems, which will accordingly cause the need to increase the number of systems to three or four An increase in the circular speed of grinding discs will contribute to a more intense removal of the surface layers of the grain, which will lead to grain reducing the amount of by-products in the form of particles of crushed kernel and flour, while reducing the yield of whole kernel and finished products. An increase in the yield of by-products will lead to the need to expand the stage of sorting grinding products due to the installation of additional machines - sieve air separators and aspiration columns.

The mixture of grinding products after each system for extracting flour is passed twice through aspiration columns or air separators and sent to grinding, which is carried out in roller machines on four systems. The ratio of the speeds of the rollers is taken as 2.5; circular speed of rollers - 3.5 m/s; placement of grooves - point by point. The interroller gap is adjusted after each system in the range of 0.6-0.1 mm. After each system, before sorting, the mixture of grinding products is additionally processed in an entoleator. Barley flour is removed after each grinding system during sorting, which is carried out in a grain disperser. Flour is selected through a sieve passage of Mo 056 mm. The output from this sieve after the first, second and third sorting system is directed to the next one, after the fourth - bran is obtained. At the final stage, control of the received flour is carried out, after which it is sent to packaging.

Example.

Received barley flour. To do this, the grain of bare barley of the "Gladiator" variety, with an initial moisture content of 12.6 96 and a mass of 2000 g, cleaned of impurities, was weighed on an automatic scale and sent to the stage of hydrothermal treatment. The grain was soaked in water heated to 607 for 240 minutes. After that, it was moistened in a special hopper with a perforated lower surface for 15 minutes, removing excess moisture from the grain at this stage and sending it to grinding, which was carried out on two grinding systems. The circular speed of the disks was set at 20 m/s. The mixture of grinding products to extract flour was passed twice through an aspiration column, after which it was sent for grinding in

From the rolling mill, which was carried out on four systems. The ratio of the speeds of the rollers was taken as 2.5; circular speed of rollers - 3.5 m/s; placement of flutes point by point.

The inter-roll gap on the first system was set at 0.6 mm, the second at 0.4 mm, at the third - 0.2 mm, and at the fourth - 0.1 mm. After each system, before sorting, the mixture of grinding products was additionally processed in an entoleator.

Sorting of grinding products was carried out in a grain separator. Flour was selected by passing a Mo 080 sieve on each system. The output from this sieve after the first, second and third was sent to the next grinding system, after the fourth - they received bran.

As a result of the processing of "Gladiator" barley, the total yield of flour was 79 95, bran (taking into account mechanical losses during grinding) - 6 95, other products (during grinding, sorting of grinding products, taking into account mechanical losses) - 15 Ob.
