Abstract

A method for the production of whole grain cereals includes impurity cleaning, water treatment, grinding and sorting of grinding products. The grain with a moisture content of not more than 14% is steamed at a steam pressure of 0.15-0.20 MPa for 4-6 minutes, dried and ground twice.

Description

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

There is a known method of producing groats from triticale grain of the pearl type, which includes cleaning the grain from foreign impurities, moistening, dewatering, fractionation, fractional peeling, sorting of the products of peeling with the separation of the hulled grain, grinding of the hulled grain to obtain pearl grain (see RF patent Mo 2537528 IPC A2ZI 1/182, VO2B

B/00, 2015).

Previously cleaned of impurities and prepared triticale grain with a moisture content of no more than 15 95 enters the grain disperser, in which the fractionation stage is carried out. The coarse fraction of the grain is obtained by sieve steps 3.2x20 mm, 3.0x20 mm and 2.8x20 mm, the fine fraction by sieve steps 2.6x20 mm, 2.4x20 mm and 2.2x20 mm. Further grain processing is carried out in two parallel streams. In the first stage, the grain is dehulled by passing it through two successive systems of vertical dehulling machines. The mixture of peeling products is separated in two stages. On the first one, the shells, flour and particles of the crushed kernel are removed from the mixture, this technological operation is carried out on one system of air separators with a closed air cycle (duoaspirators). After that, the mixture of husked and unhusked grain enters the grain spreader, where when the coarse fraction is sorted through 2.8x20 mm sieves, unhusked grain is obtained, which enters the second husking system. The exit and passage from the 2.6x20 mm sieve is the husked grain, which is sent to the grinding system. When sorting the fine fraction through sieves 2.4x20 mm, unhusked grain is obtained, which enters the second hulling system. The exit and passage from the 2.2x20 mm sieve is the husked grain, which is sent to the grinding system.

One system of BSHM grinding machines is provided for grinding husked grain. The mixture of grinding products is controlled by passing through one system of duo-aspirators and sent to packaging.

This method was chosen by the prototype.

The prototype and the claimed useful model have the following common operations: - grain cleaning from impurities; - hydrothermal treatment; - peeling;

Zo - sorting of peeling products; - grinding; - sorting of grinding products.

The disadvantage of the technological process for the production of pearl millet groats is the long duration and complexity of the technological process: the necessity of moistening and dehumidifying the grain, carrying out four dehusking systems and two grinding systems, which requires significant production areas to accommodate moistening machines, dehumidification bunkers, appropriate peeling and grinding equipment, which causes difficulties in the implementation of this process at plants of small capacity.

The useful model is based on the task of developing a method of producing whole-grain cereals, in which by changing operations (steaming instead of moistening and dehumidification, excluding peeling), grinding with one flow on two systems, as well as using triticale of a certain variety, to ensure the simplification of the technological process according to due to reducing the number of operations, their duration and increasing the output of finished products.

The task is solved by the fact that the method of production of cereals from whole grains, which includes cleaning from impurities, hydrothermal treatment, grinding and sorting of grinding products, according to a useful model, grain with a moisture content of no more than 14 95 is steamed at a steam pressure of 0.15-0.20 MPa for 4-6 minutes, dried and polished twice.

The method is carried out in the following order. Triticale grain cleaned of impurities, for example of the "Slavetne" variety, with a moisture content of no more than 14 95, enters operational bunkers.

It is monitored for magnetic impurities and directed to hydrothermal treatment with one stream.

The grain is steamed in intermittent steamers of the PZ type at a steam pressure of 0.15-0.20 MPa for 4-6 minutes, after which it is dried in vertical steam dryers of the VS type to a humidity of 13-14 95 and sent for grinding. This technological operation is carried out on two systems using peeler-grinding machines of the ZShN type, which work according to the method of intensive shell abrasion. The circular speed of abrasive disks on the first grinding system is set to 20-22 m/s, on the second 16-18 m/s. A decrease in the circular speed of the abrasive discs will lead to insufficient removal of the surface layers of the grain when it is processed on two systems, which will, accordingly, necessitate an increase in the number of grinding systems to three or four. An increase in the circular speed of the abrasive discs will contribute to a more intensive removal of the surface layers, which will lead to an increase in the number of by-products in the form of small particles of crushed core and flour, while reducing the output of the core and finished products. An increase in the yield of by-products will cause the need to expand the stage of sorting the grinding products due to the need to install additional sieve-air separators and aspiration columns.

The mixture of grinding products after the first grinding system to remove flour is passed through two systems of air separators or aspiration columns, after the second - the mixture enters the grain disperser. The output from the 2.4x20 mm sieves is whole-grain groats

Mo 1, which is sent to air and magnetic separators for control. The passage of the 2.4x20 mm sieves and the exit from the 1.8x20 mm sieves is whole-grain Mo 2 grain, which is sent to air and magnetic separators for control. The whitefish pass 1.8x20 mm is a mixture of fine ground kernel and crushed kernel particles of various sizes, which is controlled and sent for further processing into triticale flour.

Example.

Received whole grain cereals. For this, triticale grain of the "Slavetne" grade, cleaned of impurities, with an initial moisture content of 13.6 95, weighing 2000 g, was weighed on an automatic scale and sent to a periodic evaporator, where it was treated with saturated steam at a steam pressure of 0.15

MPa for 5 min., dried to a moisture content of 13 o and sent to grinding, which was carried out in one flow on two systems using peeling-grinding machines operating according to the method of intensive shell abrasion. The circular speed of the grinding discs was set to 20 m/s on the first system. on the second 16 m/s. The mixture of grinding products after the first grinding system to extract flour was passed through two systems of aspiration columns, after the second - the mixture was sent to the grain disperser. Passing through sieves 2.4x20 mm was used to obtain groats from whole grain Mo 1, passing through sieves 2.4x20 mm and passing through sieves 1.8x20 mm obtained groats from whole grain Me 2. The obtained groats were controlled by passing through an aspiration column once. The passage of the 1.8x20 mm sieves was a mixture of finely ground core and crushed core particles of various sizes, which after control in the aspiration column were sent for processing into flour.

As a result of the processing of "Slavetne" triticale grain into whole-grain groats, the total output of the finished product was 64,095, flour - 12,595 by-products and waste

Zo (taking into account mechanical losses) - 24.0 Ob.
