Abstract

The method of preparation of oats for processing involves the purification of grain from impurities, the removal of small inferior grain and the separation of refined grain into large and small fractions. The grain of the holoseric oat of a large fraction is separated in two steps. In the first stage, the grain is cleaned in an all-round picker, and in the second, it is subjected to additional control in a paddy machine.

Description

The useful model belongs to the cereal industry, in particular to methods of preparation of whole-grain varieties of oats for processing into cereals and cereal products, specifically - cereals, flakes and flour.

There is a well-known method of preparing grain of filmy varieties of oats for processing, which includes cleaning from impurities, extraction of small inferior grain, division of grain into fractions, hydrothermal treatment and waste control (see "Rules for the organization and management of the technological process at grain factories". - K .: Ministry of agro-industrial complex, 1998. - P. 36).

At the first stage, oat grain is cleaned of coarse impurities in a scalper. After that, it enters one system of air-sieve separators, where large impurities are removed through sorting sieves (4.0-4.5) x 20 mm, and fine oats together with small impurities are removed through sieves 1.8 x 20 mm. At the next stage, metallomagnetic and mineral impurities are removed, for which the grain enters a magnetic separator and a stone sorting machine, respectively. Partially cleaned grain enters two systems of grain scatterers. In the first grain disperser, small grains are removed with fine impurities through sieves 1.8x20 mm, in the second - grain is divided into fractions. The coarse fraction of grain, obtained by passing through sieves 2.2x20 mm, enters the trier-puppet selector, the small fraction obtained by the passage of sieves 2.2x20 mm - into the trier-overall separator. Grain cleaned of impurities is fractionally sent to hydrothermal treatment, which is carried out by the method of hot conditioning. At this stage, the grain is steamed in steamers of continuous action with a steam pressure of 0.05-0.10 MPa for 5 min., dehumidified for 20 min., dried to a humidity of 10-14 96, cooled and sent to husking in two fractions.

This method was chosen as a prototype.

The prototype and the claimed useful model have the following common operations: - cleaning from impurities; - extraction of small inferior grain; - division of grain into two fractions.

The disadvantage of the technological process of preparing traditional film varieties of oats for processing is the long length of the technological process, which includes a complex stage of grain fractionation, in which two systems of grain dispersers are used, stage

From the hydrothermal treatment of grain, which includes the use of periodic vaporizers and drying of grain, which requires significant production areas to accommodate the appropriate machines and causes difficulties in implementing this process in factories of small capacity.

The basis of a useful model is the task of developing a method of preparing oat grains for processing, in which, by using whole-grain oats of a certain variety, to ensure the simplification of the technological process by reducing the number of operations.

The task is solved by the fact that in the method of preparing oat grain for processing, which includes cleaning the grain from impurities, extracting small inferior grain and dividing the cleaned grain into large and small fractions, according to a useful model, the grain of whole-grain oats of the large fraction is separated in two stages. At the first stage, the grain is cleaned in a trier, and at the second stage, it is subjected to additional control in a paddy machine.

The drawing shows the technological scheme of preparation of whole-grain oat grain for processing, where: 1 - bunkers for unrefined grain; 2 - scalper;

C - automatic scales; 4 - sieve-air separator; 5 - magnetic separator; 6 - stone picking machine; 7 - grain diffuser; 8 - pupa-selector trier; 9 - trier-all-round selector; 10 - storage bunkers; 11 - paddy machine.

The method is carried out in the following order. The grain of bare oats from the bunkers for raw grain 1 is sent to the scalper 2 for preliminary cleaning. This technological operation ensures the separation of the largest coarse impurities from the grain, which are significantly larger than the grain size of the main crop, their extraction is carried out on sieves with large openings of 20x20 mm and 10x10 mm Before the main cleaning, the grain is weighed on automatic scales 3.

After that, the bare oat grain enters the sieve-air separator 4, where waste of the I-II category is removed through the passage of the upper sieve 60 (4.5-4.0) x 20 mm, and through the passage of the lower sieve 1.68x20 mm, small and thin grain together with small impurities are selected . The main grain obtained through the passage of the sieve (4.5-4.0) x 20 mm and the rise of the sieve 1.8 x 20 mm enters the pneumatic channel of the separator for the extraction of aerodynamically light and dust-like impurities. In the magnetic separator U1-BMZ 5, metallomagnetic impurities are removed, and in the stone-removing machine RZ-BKT b - mineral impurities. The grain of whole-grain oats cleaned in this way enters the grain disperser 7 for fractionation, where a coarse fraction of grain is obtained through a sieve of 2.1 x 20 mm, and a fine fraction is obtained through a passage. The fine fraction of the grain enters the trier-puppet selector 8 for cleaning, after which it is sent for processing. The coarse fraction, characterized by the content of mainly large impurities, together with unbroken and filmy grain, is sent for separation to the trier-wide separator 9 and to the storage hopper 10. From the hopper 10, the grain is directed to one system of paddy machines 11 for control, which ensures the final removal of unbroken and filmy grain from it. After that, the large fraction is sent for processing. Example.

The grain of bare-grain oats of the "Solomon" variety with a moisture content of 13.1 95, a nature of 675 g/l, a content of garbage admixture 2.3 956, grain admixture 7.095 and filmy grain 7.0 95 was sent for preparation for processing and processing. At the first stage, the grain was cleaned of coarse impurities in a scalper on appropriate sieves and weighed on automatic scales. After that, it entered the sieve-air separator, where waste of the I-II category was removed through the upper sieve (4.5-4.0) x 20 mm, and fine and thin grain together with small impurities were removed through the lower sieve 1.8x20 mm. The main grain was obtained through the passage of a sieve (4.5-4.0) x 20 mm and the rise of a sieve of 1.8 x 20 mm, the removal of aerodynamically light and dust-like impurities took place in the pneumatic channel of the separator. After that, metallomagnetic impurities were removed in a magnetic separator, and mineral impurities were removed in a stone sorting machine. The grain of whole-grain oats cleaned in this way was sent to a grain separator for fractionation, where a large fraction of grain was obtained through a sieve of 2.1x20 mm, and a fine fraction was obtained through a passage. The purification of the fine fraction was carried out in a trier-puppet separator. The coarse fraction was cleaned in a trier-oat separator and sent to a storage hopper. After that, it was controlled on the paddy machine and sent for processing.

After cleaning, the grain of bare oats had the following indicators: moisture 13.1 95, nature 715 bodies, content of garbage admixture 0.2 95, content of grain admixture 2.3 95.

During the further processing of the cleaned grain, groats from the whole kernel were produced, the total yield of which was 86.0 95, by-products and waste (taking into account mechanical losses) - 14.0 95.
