Abstract

A method of preparing barley grain for processing, which 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 glacial barley of both fractions is subjected to additional purification, whereby the grain of the small fraction is purified in the purifier-puppet, and the grain of the large fraction on the trier-purifier.

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

The closest to the useful model that is claimed is the method of grain preparation of filmy varieties of barley, which involves cleaning the grain from impurities, extracting small inferior grain, preliminary husking of the grain and control of waste (see "Rules for the organization and management of the technological process at grain factories ". - Kyiv: Ministry of Agro-Industrial Complex, 1998. - p. 36).

Grain cleaning is carried out on three systems of sieve-air separators, a magnetic separator, a stone-removing machine, a grain spreader and triers. Hulling is carried out in two stages: in the first, the grain is husked using two systems of upholstering machines, in the second - using husking-grinding machines with abrasive discs.

Cleaning from impurities begins in the sieve-air separator of the first pass, in which coarse impurities are removed through the upper sieve of 4.5x20 mm, and small inferior barley is removed along with small impurities through the passage of the sowing sieve with rectangular holes of 2.2x20 mm. The main grain, which is the exit from the 2.2x20 mm sieve after magnetic control, is sent to the stone separator, where impurities that differ from the main grain in terms of density are removed. The grain cleaned in this way is sent to the grain disperser for fractionation. The coarse fraction of the grain, obtained by passing through the 2.4x20 mm sieves, is sent to the sieve-air separator of the second pass, and the fine fraction - to the sieve-air separator of the third pass.

In the sieve-air separator of the second passage, the passage of the seed sieve with holes of 2.4x20 mm, enters the sieve-air separator of the third passage for additional separation, and the large fraction of the grain is sent to the trier-wide separator. In the sieve-air separator of the third passage, through the passage of seed sieves with holes of 2.2x20 mm, small barley is removed together with small impurities. The output of the 2.2x20 mm sieve is sent to the trier-puppet selector.

Barley grain cleaned of characteristic impurities is combined and sent in one flow to the preliminary husking, which is carried out by sequentially passing the grain through two systems of upholstering machines and two systems of AT1-ZSHN type machines. Grain prepared in this way

They are sent for processing.

This method was chosen as a prototype.

The prototype and the claimed useful model have the following common operations: - grain 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 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 basis of a useful model is the task of developing a method of preparing barley grain for processing, in which, by using whole-grain barley of a certain variety, to ensure the simplification of the technological process by reducing the number of operations.

The task is solved in the method of preparing barley grain for processing, which involves cleaning the grain from impurities, extracting small inferior grain and dividing the cleaned grain into large and small fractions, by the fact that the grain of bare barley of both fractions is subjected to additional cleaning, while the grain of the small fraction is cleaned in the trier-puppet-separator, and the grain of the large fraction on the trier-whole-separator.

The drawing presents a technological scheme for cleaning and preparing bare barley grain for processing, where: 1 - bunkers for uncleaned grain; 2 - automatic scales;

C - sieve-air separator; 4 - magnetic separator; 5 - stone picking machine; 6 - grain diffuser; 7 - trier-puppet selector; 60 8 - trier-all-round picker.

The method is carried out in the following order. The grain of bare barley, which is in the hoppers for raw grain 1, enters the automatic scales 2 for weighing, after which it is directed in one stream to the sieve-air separator 3, where the waste of the І1...ІІ category is removed through the passage of the upper sieve 4.5x20 mm of the lower sieve 2.0x20 mm - small and thin barley grain together with small impurities. The exit from the 2.0x20 mm sieve is the main grain, which, after magnetic control 4, is sent to the stone separator 5. The grain of bare barley cleaned in this way enters the grain disperser 6. In the grain disperser 6, through the exit of the 2.2x20 mm sieve, coarse grain fraction, passing through 2.2x20 mm and coming out of sieves 2.0x20 mm - small fraction.

The coarse and fine fractions received in the disperser are sent to triage. The fine fraction of the grain together with the rest of the small impurities is sent to the trier-puppet separator 7, the large fraction, which mainly contains the remains of larger impurities, enters the trier-general separator 8. After tritering, the bare barley grain is sent for processing.

Example

Barley grain of the "Achilles" variety weighing 2,000 g with moisture 12.7 95, nature 715 g/l, trash admixture content 1.4 95, grain admixture 7.095 was sent for preparation for processing and processing. The grain was weighed on automatic scales 4 and sent to the sieve-air separator 3, in which waste of the I...Y category was removed through the passage of the upper sieve 4.5x20 mm, and small and thin grain was removed through the passage of the lower sieve 2.0x20 mm.

The main grain obtained by passing a 4.5x20 mm sieve and a 2.0x20 mm sieve was directed to the extraction of metallomagnetic and mineral impurities, which was carried out in a magnetic separator 4 and a stone-removing machine 5, respectively. To separate the grain into coarse and fine fractions, the grain was sent to the grain disperser 6. The coarse grain fraction was obtained by passing through the 2.2x20 mm sieves, and the fine fraction by passing through the 2.2x20 mm sieve and passing through the 2.0x20 mm sieves. The remains of small barley were removed by passing through sieves 2.0x20 mm. The grain, divided into large and small fractions, together with the rest of the relevant impurities, was sent to the trier. The coarse fraction was cleaned in a trier-wide selection 8, the small fraction - in a trier 7.

After cleaning, the grain of bare barley had the following indicators: moisture 12.7 95, nature 741 g/l, content of garbage impurity 0.2 95, content of grain impurity 1.7 90. Cleaned in this way

The grain was sent for processing into cereals.

During the further processing of cleaned grain, groats from the whole kernel were produced, the total yield of which was 84.0 95, by-products and waste (taking into account mechanical losses) - 16.0 9.
