Description

The useful model belongs to the grain industry, in particular to methods of processing whole-grain varieties of oats into grain products, specifically flattened grains.

There is a known method of producing barley flakes from hulled grain, which involves cleaning from impurities, soaking the grain in water at a temperature of 18-20 "C for 34 hours until the humidity reaches 38-40 96, drying the grain with IR rays at a wavelength of 0.9- 1.1 μm and a radiant flux density of 12-14 kW/m? for 2.0-2.5 min to a humidity of 30-32 95 and processing

IR rays with a wavelength of 0.9-1.1 μm and a radiation flux density of 18-20 kW/m? for 100-115 s until the grain reaches a temperature of 160-170"7C with its subsequent flattening into a flake 0.6-0.7 mm thick (see RF patent Mo 2512240 A23З11/10, 2014).

The analogue and the claimed useful model have the following common operations: - grain cleaning from impurities; - hydrothermal treatment; - flattening

However, the known method requires the use of special technological equipment for drying and processing of grain with IR rays, the installation of special containers for soaking, which causes difficulties in the implementation of this process at factories of low productivity.

There is also a known method of production of rolled oat groats, which involves cleaning of impurities, calibration of grain into two fractions, hydrothermal treatment, peeling by fractions, separation of peeling products, grain separation, re-flaking, grinding, separation of grinding products, steaming of high or first grade groats, tempering , flattening, sorting and control of flattened groats (see "Rules for the organization and management of the technological process at groat factories". - Kyiv: Ministry of Agro-Industrial Complex, 1998. - P. 36-38).

Grain cleaned of impurities and divided into large and small fractions is sent to hydrothermal treatment. The grain is fractionally steamed in steamers of continuous action at a steam pressure of 0.05-0.10 MPa for 5 min, tempered for 20 min, dried to a moisture content of 10-14 95, cooled and sent in two streams to peeling, which is carried out on two peeling systems with using peeling stands or centrifugal peelers. Product sorting

Peeling is provided in several stages. At the first stage, flour and particles of the crushed kernel are removed from burats by passing through a sieve with holes of 2.0 mm, a mixture of shelled, unshelled grains and husks is obtained through this sieve, which enters two systems of air separators. After removing the husk, the mixture of shelled and unshelled grains is sent for separation into two systems of paddy machines. Grinding of the shelled whole core is carried out in one stream on one grinding system. Grinding products are sorted in a grain separator. Flour and particles of crushed kernel are removed by passing sieves with 4 holes of 2.0 mm or 1.2x20 mm. The whole polished core is obtained by passing through a sieve with holes of 2.5x20 mm, which is additionally controlled on two systems of paddy machines. After control in the paddy machines, the higher or first grade groats are sent for steaming, which is carried out in a steamer of continuous action at a steam pressure of 0.05-0.10 MPa. After steaming, the groats are tempered for 20-30 minutes and sent for flattening in a rolling machine. The flattened products are sieved on sieve-air separators, where particles of the crushed core are separated by passing through a sieve with holes of 9 2.0 mm. After that, flattened groats are controlled on two systems of aspiration columns, and after monitoring for magnetic impurities, they are sent to bunkers for finished products. The yield of flattened groats is 45 95.

This method was chosen by the prototype.

The prototype and the claimed useful model have the following common operations: - grain cleaning from impurities; - grinding; - sorting of grinding products; - hydrothermal treatment of the core; - flattening; - sorting of flattening products.

However, the known method involves a long duration and complexity of the technological process: 2 peeling systems for each fraction, 8 paddy machines at the grain sorting and control stages, b sorting systems at different stages of production, grain steaming in batch steamers, which requires significant production areas for placement of appropriate technological 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 rolled oat groats, in which, by changing the order of operations - processing in one stream, eliminating the stages of grain steaming, husking, sorting of husking products, grain splitting, introduction of cutting/shredding of the kernel, sorting of cutting products/ grinding, steaming of the cut kernel, as well as the use of whole-grain oats of a certain grade, to ensure the simplification of the technological process by reducing the number of operations and their duration and increasing the yield of finished products.

The task is solved in the method of production of flattened oats from oats, which involves cleaning the grain from impurities, grinding, sorting the grinding products, hydrothermal treatment of the core, flattening and sorting the flattening products by the fact that, unlike the prototype, grain with a moisture content of no more than 1495 is ground , fractionated, polished once, steamed at a steam pressure of 0.10-0.15 MPa for 2-4 min, tempered for 5-7 min and flattened.

The method is carried out in the following order. Cleaned from impurities, whole-grain oat grain, for example, of the "Salomon" variety, with a moisture content of no more than 14 95, enters the cutting/grinding stage in one stream, which is carried out in grain cutters or on rolling machines with special flute cutting. The cutting/shredding products are sorted in a grain separator

A1-BRU, in which the nucleus is divided into fractions. Coarse is obtained by passing through a sieve of 0 2.2 mm, fine - by passing through. Flour is removed by passing through a Mo 080 sieve. Each fraction for extracting flour is passed separately through two systems of air separators or aspiration columns. After that, the core of the large and small fraction is sent separately for grinding, which is carried out on the same system using peeling-grinding machines that work according to the principle of intensive abrasion of the shells. The circular speed of discs when grinding both fractions is set at 14-16 m/s. A decrease in the circular speed of the discs will lead to insufficient removal of surface layers during processing on one system, which will, accordingly, necessitate an increase in the number of grinding systems to two or three.

An increase in the circular speed of the discs will contribute to a more intensive removal of the surface layers of grain, which will lead to an increase in the number of by-products in the form of small particles of crushed kernel and flour, while reducing the yield of finished products. An increase in the yield of by-products will lead to the need to expand the product sorting stage

From grinding due to the installation of additional machines - sieve air separators and aspiration columns. The mixture of grinding products for the extraction of flour enters two systems of air separators or aspiration columns. After that, the crushed core of both fractions is sent to hydrothermal treatment. Coarse and fine fractions are steamed in a batch steamer at a steam pressure of 0.10-0.15 MPa for 2-4 min, tempered for 5-7 min and flattened. Flattening is carried out in roller machines on smooth rollers with a working gap of 0.4-0.6 mm. Flattened products are sorted in a grain spreader or sieve-air separator, where flattened groats are obtained by passing through a Mo 1.0 sieve, flour and small kernel particles are removed by passing through this sieve. Flattened groats are sent to belt dryers for drying to a moisture content of no more than 14 95. After drying, the flattened core of the coarse fraction is Me 1 groats, and the fine grain is Me 2 groats. The flattened groats are checked for the presence of metallomagnetic impurities and sent to packaging or to bunkers for finished products .

Example

We received flattened oats. For this purpose, the grain of naked oats of the "Salomon" variety, with an initial moisture content of 13.3 96 and a weight of 2000 g, cleaned of impurities, was weighed on an automatic scale and guided for cutting, which was carried out in a grain cutter. Sorting was carried out in a grain spreader. Passing through sieves 0 2.2 mm, a large fraction of the cut core was obtained, and a small fraction was obtained through the passage.

Flour was removed by passing through a Mo 080 sieve. Both fractions were passed through two systems of aspiration columns to remove flour residues. After that, grinding was carried out. This stage was carried out on one system using a peeling-grinding machine, which works on the principle of intensive shell abrasion. The circular speed of the discs when grinding both fractions was set to 16 m/s. The mixture of grinding products was passed through two systems of aspiration columns and directed to vaporization. The coarse and fine fractions were separately steamed in a batch steamer at a steam pressure of 0.15 MPa for 2 min, tempered for 5 min and sent to flattening, which was carried out in a roller machine on smooth rollers with a working gap of 0.4 mm. Ivy products were sorted in a grain separator. When processing the large fraction by passing through a sieve Mo 1.0, flattened groats Mo 1 were obtained, small - Mo 2, which at the final stage were dried in a dryer to a humidity of 14 95. Flour and small kernel particles were removed by passing through a sieve Mo 1.0.

As a result of the processing of oats of the "Salomon" variety, the total output of flattened grains was 71 95, because secondary raw materials (taking into account mechanical losses) - 29 95.
