UA120924U - A METHOD FOR THE PROCESSING OF GRAIN MINE IN A PLUSHEN GROUP - Google Patents

Abstract

The method of processing millet grain into flattened cereals involves cleaning the grain from impurities, water heat treatment, peeling, sorting of peeling products, flattening, sorting the products of flattening and drying. Grain with a moisture content of not more than 14% is peeled on the roller mill system in two stages. In the first - in the machine with two decks, in the second - in the machine with one deck, the resulting kernel is steamed at a vapor pressure of 0.20-0.22 MPa, for 7-10 min, tempered for 3-5 min and flattened at the working gap 0 , 5-0,7 mm.

Description

The useful model belongs to the cereal industry, in particular to methods of processing millet into cereal products, specifically flattened groats.

There is a known method of producing flakes from non-traditional raw materials, which includes cleaning millet grains from impurities, fractionation, soaking, dehumidification, steaming, tempering, drying, cooling, peeling, sorting of peeling products, flattening, sorting of flattening products and drying of flakes (see RF patent Mo 2519737 IPC A2gZI. 1/164 of 2012).

The millet grain is cleaned of impurities in a separator, fractionated and directed to soaking, adding 7-995 of water and moistening for 0.5-3.0 hours. until the grain reaches a humidity of 18-22 95. At the next stage, the grain is steamed in a steamer at a steam pressure of 0.1-0.4 MPa for 2-8 minutes until the grain reaches a humidity of 24-30 95, it is also possible to steam at a steam pressure of 0.1 -0.4 MPa for 3 min, after which the pressure is released and the grain is tempered in the vaporizer for 2-8 min. The grain is dried in a "fluid bed" to a humidity of 23-25 96 and cooled to a temperature of 20-25 "C, as a result of which the flower films dry quickly and crack. After that, the grain is husked with the removal of the flower films and flattened on a threshing machine. The flattening products are sieved and dried to a humidity of 11-14 95.

This method is chosen as the closest analogue.

The closest analogue and the proposed useful model, which is claimed, have the following common operations: - grain cleaning from impurities; - hydrothermal treatment; - peeling; - sorting of peeling products; - flattening; - sorting of flattening products; - drying

The disadvantage of the technological process of the production of flakes from non-traditional raw materials is the long duration and complexity of the hydrothermal treatment stage, which includes soaking the grain

Zo in water, dehumidification, steaming, drying and cooling, which requires significant production areas to accommodate tanks for soaking, dehumidification, dryers and cooling columns, which will cause difficulties in the implementation of this process in factories of small productivity.

The basis of a useful model is the task of developing a method of processing millet grain into flattened groats, in which by excluding from the technological process soaking, dehumidification, steaming, tempering, drying and cooling of grain before the main stages of processing and including hydrothermal treatment of the hulled kernel (groats), as well as the use of millet of a certain grade, to ensure the simplification of the technological process by reducing the number of operations and their duration.

The task is solved in the method of processing millet grain into flattened groats, which involves cleaning the grain from impurities, hydrothermal treatment, husking, sorting of husking products, flattening, sorting of flattening products and drying, according to a useful model, grain with a moisture content of no more than 14 95 is husked per system of rolling deck machines in two stages: on the first - in a machine with two decks, on the second - a machine with one deck, the obtained core is steamed at a steam pressure of 0.20-0.22 MPa for 7-10 minutes, tempered for 3-5 min and flatten with a working gap of 0.5-0.7 mm,

The method is carried out in the following order.

Cleaned from impurities, millet grain, such as the "Poltava Golden" variety, with a moisture content of no more than 14 95, is sent to the system of roller deck machines with two decks for husking.

The husking mode is set so as to obtain 95 husked grains after the 88-92 system.

The mixture of peeling products is controlled by passing through a system of air separators or aspiration columns, in which the husk, flour and particles of the crushed kernel are extracted. Hulled and unhulled grain enters a step-hulling system, which uses roller deck machines with one deck. The husking mode is set so as to obtain 94-97 95 husked grains after the ladder system. The mixture of peeling products for the extraction of husk and flour is sent to two systems of air separators or aspiration columns. The entire kernel is moistened to a humidity of 16-18 95, dehumidified for 1.0-1.5 hours. and sent to vaporization, which is carried out in intermittent vaporizers of the PZ type at a steam pressure of 0.20-0.22 MPa for 7-10 minutes. 60 The core prepared in this way is flattened on flattening machines on smooth rollers.

The ratio of the circular speeds of the rollers during flattening is set to 1, the gap between the rollers is 0.5-0.7 mm. The mixture of flattening products is sent to belt dryers for drying, where it is dried to a moisture content of no more than 14 95. After that, the mixture is passed through two systems of air separators or aspiration columns to remove aerodynamically light impurities (husk, flour and small particles of crushed kernel). The resulting flattened cereal is controlled for the presence of metallomagnetic impurities and sent to packaging or to bunkers for finished products.

Example.

We received flattened groats. For this purpose, millet grain of the "Poltava Golden" variety, with a moisture content of 13.4 96, cleaned of impurities, was sent to husking, which was carried out in a roller deck machine with two decks. The amount of dehusked grain in the mixture after dehusking was 90-95. The dehusking product mixture was sent to an aspiration column to extract the husk, partially flour and small particles of the crushed kernel. Whole husked and unhusked grains were sent to a rolling deck machine with one deck (ladder dehusking system). The amount of husked grain in the mixture after husking was 95,905. The mixture of husking products for the extraction of husk and flour was directed to airing on two systems of aspiration columns. After that, the core was sent to a batch steamer, where it was steamed at a steam pressure of 0.20 MPa for 7 min and sent to flattening, which was carried out in a flattening machine on smooth rollers. The ratio of the circular speed of the rollers was set to 1, the inter-roller gap - 0.6 mm. The mixture of flattening products was sent to a dryer, where it was dried to a moisture content of 14 95 and to two systems of aspiration columns, in which flour, particles of crushed kernel and husk were extracted. After removal of aerodynamically light impurities, the obtained flattened millet kernel was characterized as flattened groats.

As a result of the processing of "Poltava Golden" millet grain into flattened groats, the total output of the product was 70 95, by-products and waste (including mechanical losses) - ЗО 9.
