Abstract

Method of preparation of polby for processing, which involves purification of grain from impurities and removal of small inferior grain, whereby the purified grain is subjected to additional purification in two stages, the first remove the small grain impurities in the three-puppet, on the second remove the impurities in a tri-orifice filter, and the grain thus cleaned is subjected to final purification from aerodynamically light impurities in an air separator or aspiration columns.

Description

The utility model relates to the cereal industry, in particular to methods of preparing spelled for processing into cereals and cereal products, specifically cereals, flakes and flour.

There is a well-known method of preparing the grain of durum wheat varieties for processing, which involves cleaning the grain from impurities, extracting small inferior grain, hydrothermal treatment of grain and waste control (see "Rules for the organization and management of the technological process at grain factories". - Kyiv: Ministry of of the agro-industrial complex, 1998. - pp. 60-65).

The analogue and the claimed useful model have the following operations in common: - grain cleaning; - extraction of small inferior grain.

The disadvantage of the technological process of preparing durum wheat grain for processing is the long length and complexity of the technological process: the stage of hydrothermal treatment involves heating water to a temperature of 35...45 "С, humidification on special humidifying machines, humidification for which it is necessary to provide special bunkers, technological process preparation includes a complex stage of grain husking on two husking systems with the use of upholstery machines and two additional aspiration systems that provide preliminary sorting of husking products, which requires significant production areas to accommodate the corresponding machines and difficulties in implementing this process at small-capacity plants.

There is also a well-known method of grain preparation of filmy varieties of barley, which involves cleaning the grain from impurities, extracting small inferior grain, husking the grain and controlling waste (see "Rules for the organization and management of the technological process at grain factories". - Kyiv: Ministry of Agro-Industrial Complex, 1998. - p. 36).

This method and the claimed useful model have the following common operations: - grain cleaning from impurities; - extraction of small inferior grain.

The disadvantage of the technological process of preparing traditional film varieties of barley for processing is the long length of the technological process, which includes preliminary husking of grain on four consecutive husking systems: two consecutive passes of upholstery machines and machines of the A1-ZShN type, installation of two additional air separator systems for intermediate sorting of husking products , which requires significant production areas to accommodate the appropriate machines and difficulties in implementing this process at small-capacity factories.

The method of preparation of spelled grains for processing is closest to the useful model that is claimed, which is described in the method of production of groats from spelled with a total yield of finished products of 55 95, which involves cleaning the grain from impurities, hydrothermal treatment, peeling, sorting of peeling products, grain separation , control of finished products (see RF patent Mo 2371250 IPC VO283/00, B0781/00 2006).

Dry whole, unhusked spelled grain of the "Belka" breeding variety, with a film thickness of up to 18 95 and a moisture content of 14 905, after weighing, is directed to be cleaned of impurities in the air-sieve separator A1-BMO-6. During the two-time sequential separation, large impurities are separated by passing through sieves with rectangular holes in the size from 1.1x20 to 12.0x50 mm. Fine impurities (fine grains) are separated by passing through sieves with rectangular holes in the size from 0.5x8 to 1.0x10 mm. Metallomagnetic impurities are removed with the help of magnets. Non-magnetic impurities are removed separately during sieving and subsequent hydrothermal treatment. After cleaning and separation, the grain is subjected to hydrothermal treatment, which consists in moistening the grain with potable water in the AT1-BSHU humidification machine to a humidity of 16,956, followed by dehumidification for 1.7-1.8 hours, after which the grain is sent for processing.

This method was chosen by the prototype.

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

The disadvantage of the technological process of preparing spelled grain for processing is the complexity and length of the stage of hydrothermal treatment of grain, which involves the use of drinking water for moistening, the use of special moistening machines and the need to place bunkers for moistening at the enterprise, which requires significant production areas and difficulties in implementing this process on factories of small capacity.

The basis of a useful model is the task of developing a method of cleaning and preparing spelled grain, in which by changing modes (using a different type of separators), introducing special operations into the technological process (cleaning from impurities by density), as well as using spelled of a certain grade, to ensure simplification technological process by reducing the number of operations and increasing the yield of finished products.

The task is solved in the method of preparing spelled for processing, which involves cleaning the grain from impurities and removing small inferior grain, by subjecting the cleaned grain to additional cleaning in two stages, in the first stage, small grain impurities are removed in a trier-puppet separator, in the second stage, impurities are removed , which exaggerate the spelled grain by length in a trier-oat separator, and the grain cleaned in this way is subjected to final cleaning from aerodynamically light impurities in an air separator or aspiration columns.

The method is carried out in the following order. Spelled grain, which is in bunkers for raw grain, is sent to a scalper for pre-cleaning and weighing on automatic scales, after which it is sent to sieve-air separators, in which, passing through the upper sieve of 4.5x20 mm, the largest particles are separated from the grain mixture impurity

Through the passage of the lower sieve 1.5x20 mm, in the separator, small grains are removed. The passage of the sieve 4.5x20 mm and the exit from the sieve 1.5x20 mm is the main grain, from which, when passing through the pneumatic channel of the separator, aerodynamically light and dusty impurities are removed. After that, the grain is sent to a magnetic separator and a stone sorting machine, which are used to extract magnetic and mineral impurities, respectively. The grain cleaned in this way is sent to triage. At the first stage, small grain impurities are removed in the doll-separator trier, at the second stage - in the oat-separator trier, impurities that differ from the main grain in length are removed. Spelled grain cleaned of impurities is sent for control to air separators, where the final removal of aerodynamically light impurities is carried out, after which it is sent to processing in one stream.

Example

Spelled grain of the "Dawn of Ukraine" variety weighing 2,000 g with a moisture content of 12.0 95, a nature of 390 g/l, a percentage of waste admixture 2.095, grain admixture 5.195 was sent for preparation for processing and processing. After cleaning in scalpers, the grain was weighed on automatic scales and sent to sieve-air separators. In the course of this operation, the largest impurities, small and slender grain were removed from the mixture, and when the grain passed through the pneumatic

From the channel of the separator, partially aerodynamically light components: films, flour, dust, particles of crushed grain, etc. After that, the grain was subjected to magnetic control and removal of mineral impurities, which was carried out in magnetic separators and stone sorting machines, respectively. At the next stage of cleaning, the grain was sent to the trier-puppet-separator, in which the extraction of small impurities was carried out, and for the extraction of long impurities - to the trier-all-round separator. At the final stage of cleaning, the grain was subjected to the control of aerodynamically light impurities, which was carried out on aspiration columns.

As a result of the preparation of spelled grain for processing, the main impurities were isolated from the initial mixture, which complicate further processing and reduce the quality indicators of the finished products. Spelled grain after cleaning had the following parameters: moisture content 12.0 95, nature 410 g/l, content of waste admixture 0.2 95, content of grain admixture 2.2 95.

During the further processing of grain cleaned of impurities, groats were produced from whole spelled kernels, the total yield of which was 63.5 95, by-products and waste (taking into account mechanical losses) - 36.5 9".
