The grinded core is steamed at a vapor pressure of 0.10-0.15 MPa for 2-4 min, dried to a moisture content of not more than 14%, crushed, sorted on one system. Particle kernels with a particle size greater than 2.5 mm and less than 2.0 mm are controlled and directed to the packing of cereals, and kernels of a fraction with a particle size less than 2.0 mm are sent for control and grinding into flour.

Description

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

There is a well-known method of processing filmy varieties of barley into groats with a total output of 6595 finished products, which involves cleaning grain from impurities, husking, preliminary grinding, sequential grinding of the kernel, sorting of grinding products, grinding of medium-sized fractions, sorting and control of groats (see " Rules for the organization and management of the technological process at grain factories". Kyiv: Ministry of Agro-Industrial Complex, 1998. pp. 53-56.

Barley grain cleaned of characteristic impurities is sent to peeling, which is carried out by sequentially passing through four peeling systems. Existing technology allows the stage of hydrothermal treatment of grain before husking. The grain is steamed at an excess steam pressure of 0.20 MPa for 3 min, dried to a moisture content of no more than 15 95 and sent to husking. At the first stage, barley is husked on two systems of upholstering machines, on the second - on two systems of husking-grinding machines of the АТЙ-ЗШН type. Hulled barley (pensak) is sent to grinding, which is carried out on one or two grinding systems, after which the grinding stage is carried out, which is implemented on four consecutive grinding systems with simultaneous sorting. On all sorting systems, small particles of the crushed core are removed by passing through metal-woven sieves Mo 080 and directed to flour control. The largest particles obtained by passing metal woven sieves Mo 2.8 (on the first and second grinding systems) and Mo 2.5 (third grinding system) after control in air separators are sent for additional grinding on roller machines of the following systems. Coarse particles from the diffuser of the last grinding system, obtained by the rise of the Mo 2.0 sieve, after the extraction of small particles in the air separator, are returned to the roller machine of the third grinding system. Products of medium size, obtained by passing through sieves with openings of 2 1.8 and 1.5 mm, are blown and sent to grinding. The small products that have passed through the perforated sieves with openings of 21.8 and 1.5 mm are a mixture of barley grains of different numbers, which after processing in air separators are sent to the stage of steep sorting. One system is used for grinding medium-sized products, after which they enter the first sorting system of the stage of sorting barley groats. At the stage

From sorting, which is implemented on three systems, barley groats are divided on the corresponding sieves into three numbers.

This method was chosen as a prototype.

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

However, the known method involves a long duration and complexity of the technological process: 3-4 peeling systems, 1-2 grinding systems, 4 systems for grinding the polished core, a complex three-stage sorting of crushed grain, which requires significant production areas to accommodate the appropriate machines and difficulties in implementation of this process at plants of small capacity.

The useful model is based on the task of developing a method of producing oat groats, in which, by changing the order of operations, eliminating the stages of grain steaming, husking, sorting of husking products, shortening the stage of groat sorting, introducing steaming of polished kernels, as well as using whole-grain oats of a certain grade, to ensure 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 by cleaning grains from impurities, hydrothermal treatment, grinding, sorting of grinding products, grinding and sorting of grinding products, by the fact that, unlike the prototype, the polished core is steamed at a steam pressure of 0.10-0.15 MPa 2-4 min, dried to a moisture content of no more than 14 95, crushed, sorted on the same system, while the cores of the fraction with a particle size of more than 2.5 mm and less than 2.0 mm are controlled and directed to packaging of cereals, and the cores of the fraction with with a particle size of less than 2.0 mm is directed to control and grinding into flour.

The method is carried out in the following order. Cleaned from impurities, whole-grain oat grain, for example, of the "Salomon" variety, is sent for grinding. This stage is carried out in grinding machines that work according to the principle of intensive abrasion of shells of the ZShN type. The circular speed of the disks is set at the level of 18-20 m/s. A decrease in the circular speed of the disks will lead to insufficient removal of surface layers when processing grain on one system, which will accordingly cause the need to increase the number of grinding systems to two or three.

Increasing the circular speed of the discs 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 particles of crushed kernel and flour, while reducing the yield of the whole kernel and finished products. An increase in the output of by-products will lead to the need to expand the stage of sorting grinding products due to the installation of additional machines - screen air separators and aspiration columns.

The mixture of grinding products to extract aerodynamically light components is directed to two systems of aspiration columns or air separators. The polished core is subjected to vaporization, which is carried out in a type 113 intermittent vaporizer at a steam pressure of 0.10-0.15 MPa for 2-4 minutes. The core is dried to a moisture content of no more than 14 95 and sent for grinding, which is carried out in rolling machines with special cutting of rolls or cutting into sharp grain. Sorting of grinding/cutting products is carried out in grain spreaders A1-BRU. Coarse kernel particles obtained by passing through sieves b 2.5 mm are sent to flour control, which is carried out by passing them twice through air separators or aspiration columns, after which the crushed kernel is characterized as oat groats Mo 1. Passing through sieves 0 2.0 mm gives medium kernel particles , which after passing twice through air separators or aspiration columns, are characterized as oat groats

Mo 2. Oat groats Mo 1 and Mo 2 are controlled for the content of metallomagnetic impurities and sent to the appropriate bunkers for finished products or for packaging. The small-sized particles obtained by passing through metal-woven sieves Mo 080 after control on two systems of air separators are sent for grinding into flour. Flour is removed by passing through sieves Mo 080.

Example

Received oat groats. For this purpose, the grain of bare oats of the "Salomon" variety, with an initial moisture content of 13.1956 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. At this stage

They used a peeling-grinding machine that works on the principle of intensive shell abrasion. The circular speed of the discs was set at 18 m/s. The mixture of grinding products for extracting flour was passed through two systems of aspiration columns and directed to vaporization, which was carried out in a periodic vaporizer at a steam pressure of 0.10 MPa for 2 min. The kernel was dried to a moisture content of 14 95 and cut in a grain cutter.

Sorting of cutting products was carried out in a grain spreader. Coarse kernel particles obtained by passing through sieve 2 2.5 mm after passing twice through aspiration columns were characterized as oat groats Mo 1. Oat groats Mo 2 were obtained by passing through sieve E 2.0 mm after passing twice through aspiration columns. The small-sized particles obtained by passing through metal woven sieves Mo 080 after control on two systems of aspiration columns were sent for grinding into flour. Flour was removed by passing through a Mo 080 sieve.

As a result of the processing of oats of the "Salomon" variety, the total output of crushed Me1-Me2 grains was 74 95, flour - 10 95, secondary raw materials (taking into account mechanical losses) - 16 95.
