UA124504U - METHOD OF PRODUCTION OF FLOUR WITH BARLEY - Google Patents

Abstract

A method of producing barley flour involves the purification of grain from impurities, crushing and sorting of crushing products. The grain of holoseric barley with a moisture content of not more than 15% is ground on four systems, with the crushing products after each system additionally processed in the entoleiter.

Description

The useful model belongs to the cereal industry, in particular to methods of processing whole grain barley into cereal products, specifically barley flour.

A known method of producing barley flour with a yield of 7095, which includes cleaning the grain from impurities, three-fold peeling in upholstery machines, two-fold peeling in peelers that ensure intensive abrasion of the shells, grinding into six chaffs (dr. s.) and six grinding (r. s. ) systems, processing of 5- and 6-year-old seeds on brush machines, obtaining flour by sifting on sieves with a hole size of 315-280 μm (Shvetsova,

IA. Production of flour from grain and seeds of non-traditional crops / IA. Shvetsova, E.N.

Gavrilova, I.V. Kuzmenkova. - M: TsNDITED of grain products, 1994, 26 p.).

The analogue and the claimed useful model have the following common operations: - grain cleaning from impurities; - grinding; - sorting of grinding products.

The disadvantage of the technological process of barley flour production is the long duration of the technological process (the need to carry out three-time husking of grain in upholstery machines, two-time husking using machines of the A1-ZSHN type, the presence of a complex grinding stage, which involves 6 shredding and grinding systems, the use of brush machines), which requires significant production areas for the placement of appropriate technological equipment and causes difficulties in the implementation of this process in factories of low productivity.

There is also a known method of producing barley flour, which includes cleaning the grain from impurities, hydrothermal treatment, grinding and sorting (see RF patent Mo 2245192 IPC В02С9/04, 2005).

Barley grain is cleaned of impurities, moistened to a humidity of 21-22 95 and dehumidified for 18-20 hours. The grain prepared in this way is roasted at a temperature of 210-220" for 2-3 minutes, while the moisture content of the grain is reduced to 8-995. After roasting, grinding is carried out in a rolling machine. Grinding products are sorted by size in a spreader. Sieve output 2 4.2 obtained during sorting, it is returned for re-grinding.

The passage of the sieve 2 4.2 and the exit of the Mo 080 sieve are directed to aspiration, after which it is ground on three shredding and three grinding systems to flour, which is obtained when sifting through the passage of kapron whitefish Mo 27. The yield of flour is 69-72 9.

This method was chosen as a prototype.

The prototype and useful model, which is claimed, have the following common operations: - grain cleaning from impurities; - grinding; - sorting of grinding products.

However, the known method involves a long duration and complexity of the technological process: carrying out the stage of hydrothermal treatment involves humidification and dehumidification for 18-20 hours, roasting in special machines, which requires significant production areas for placing bunkers and appropriate technological equipment, which causes difficulties in implementation of this process at factories of low productivity.

The basis of a useful model is the task of developing a method of producing flour from barley, in which, by eliminating moistening and roasting, reducing the grinding stage, as well as using whole-grain barley of a certain variety, 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 production of flour from barley, which involves the cleaning of grain from impurities, grinding and sorting of grinding products, by the fact that, according to a useful model, whole grain barley grain with a moisture content of no more than 15 95 is ground on four systems, while the grinding products after of each system is additionally processed in an entoleator.

The method is carried out in the following order. Cleaned from impurities, the grain of bare barley, for example, of the "Gladiator" variety with a moisture content of no more than 15 95, is sent to grinding, which is carried out in rolling machines on four systems.

The ratio of the speeds of the rollers is taken as 2.5; circular speed of rollers - 3.5 m/s; placement of grooves - point by point. The interroller gap is adjusted after each system in the range of 0.6-0.1 mm. After each system, before sorting, the mixture of grinding products is additionally processed in an entoleator.

Barley flour is removed after each grinding system during sorting, which is carried out in a grain disperser. Flour is selected by passing through a Mo 080 sieve. After the first, second and third systems, the output from this sieve is directed to the next one, and after the fourth - bran is obtained. At the final stage, control of the received flour is carried out, after which it is sent to packaging.

Example.

Received barley flour. For this purpose, the grain of bare barley of the "Gladiator" variety, with an initial moisture content of 13.5 96 and a mass of 2000 g, cleaned of impurities, was weighed on automatic scales and sent to grinding, which was carried out on four systems.

The ratio of the speeds of the rollers was taken as 2.5; circular speed of rollers - 3.5 m/s; placement of grooves - point by point. The inter-roll gap on the first system was set at 0.6 mm, the second - 0.4 mm, the third - 0.2 mm, the fourth - 0.1 mm.

After each system, before sorting, the mixture of grinding products was additionally processed in an entoleator. Grinding products were sorted in a grain separator.

Flour was selected by passing a Mo 080 sieve on each system. The output from this sieve after the first, second and third was sent to the next grinding system, after the fourth - they received bran.

As a result of the processing of "Gladiator" barley, the total yield of flour was 71 95, bran (taking into account mechanical losses during grinding) - 29 95.
