UA124444U - 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 the holosare barley is ground on one system, ground on three systems. The crushing products after the third crushing system are further 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.

There is a known method of producing barley flour with a yield of 7095, which includes grain cleaning from impurities, three-fold peeling in upholstery machines, two-fold peeling on peelers that ensure intensive abrasion of the shells, grinding on six shredding systems (dr. s.) and six grinding systems ( r. c), processing of stairs from 5 and 6 dr. c. on brush machines, obtaining flour by sieving on sieves with a hole size of 315-280 microns (Shvetsova, I.A., Production of flour from grain and seeds of cereal and non-traditional crops, I.A.

Shvetsova, E.N. Gavrilova, I.V. Kuzmenkova. - M.: Tsniyitsy khleboproduktov, 1994. - 26 p.)

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

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

The closest to the claimed useful model is the method of production of barley flour, which includes cleaning the grain from impurities, hydrothermal treatment, grinding and sorting (see RF patent Mo 2245192 IPC VO2S 9/04, 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 sieve 2 4.2 and the exit of sieve Mo 080 are directed to aspiration, after which they are ground on three shredding and three grinding systems to flour, which is obtained when sifting through the passage of kapron sieve Mo 27. The yield of flour is 69-72 95.

This method is chosen as the closest analogue.

The closest analogue and the claimed useful model have the following operations in common: 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 hydrothermal treatment of grain and roasting, shortening the grinding stage, including grinding and processing of grinding products in the entoleator, as well as using whole grain barley of a certain variety, to ensure the simplification of the technological process due to reducing the number of operations and their duration.

The problem is solved by the fact that in the method of production of flour from barley, which includes cleaning of grain from impurities, grinding and sorting of grinding products, according to a useful model, whole grain barley grain is ground on one system, ground on three systems, while grinding products after the third grinding systems are additionally processed in an entoleator.

The method is carried out in the following order. Cleaned from impurities, bare barley grain, such as the "Gladiator" variety, with a moisture content of no more than 14 95, is sent to grinding in one stream. This stage is carried out in grinding machines that work according to the principle of intensive abrasion of shells, such as ZShN. The circular speed of the disks is set at 16-18 m/s.

A decrease in the circular speed of the disks will lead to insufficient removal of the surface layers of the grain during processing on one system, which will, accordingly, necessitate an increase in the number of systems to two or three. An increase in the circular speed of the grinding wheels will contribute to a more intense removal of the surface layers of the grain, which will lead to an increase in the number of by-products in the form of particles of crushed kernel and flour, while reducing the yield of the whole kernel and finished products. An increase in the yield of by-products will lead to the need to expand the stage of sorting grinding products due to the installation of additional machines - sieve air separators and aspiration columns.

The mixture of grinding products for the extraction of flour is passed through a system of aspiration columns or air separators and directed to grinding, which is carried out in rolling machines on three 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 0.5-0.1 mm. After the third grinding system, additional processing of the mixture of products in the entoleator is provided. Barley flour is removed after each grinding system during sorting, which is carried out in a grain disperser. Flour is selected through a sieve of Mo 067 mm. The output from this sieve after the first and second sorting system is directed to the next one, after the third - 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 13.95 and a weight of 2000 g, cleaned of impurities, was weighed on automatic scales and sent for grinding, which was carried out on one grinding system. The circular speed of the disks was set at 16 m/s. The mixture of grinding products to extract flour was passed through an aspiration column, after which it was sent for grinding in a rolling machine. Grinding was carried out on three 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 0.5 mm, the second - 0.3 mm, and the third - 0.1 mm. After the third grinding system, additional processing of the mixture in the entoleator was carried out before sorting. Grinding products were sorted in a grain separator.

Flour was selected by passing through a Mo 067 sieve on each system. The output from this sieve after the first and second was directed to the next crushing system, after the third - they received bran.

As a result of the processing of "Gladiator" barley, the total yield of flour was 74 95, bran (taking into account mechanical losses during grinding) - 14 95, other products (during grinding,

From the sorting of grinding products, taking into account mechanical losses) - 12 Ob.
