Processing line for the production of high-grade flour from cereals

The utility model relates to the milling industry, in particular to equipment for grinding, crushing grain and processing it into flour,

A known production line for the production of varietal flour from grain crops, including sequentially located and interconnected grain silos, equipment for primary and secondary cleaning of grain, its moistening and smoothing, grinding systems large and small with roller pairs and cupboard screenings, and also channels for transporting grain and grinding products, moreover, it is additionally equipped with a hammer mill and a unit for eliminating flour from grains, which are located in front of the grinding systems minutes (see, the specification to RF Patent, №2156166, IPC: V02S9 / 04, Bulletin of Inventions, Utility Models, № 26 - 2000 g),

The disadvantage of the closest analogue is the inability to obtain flour of large size,

The creation of a real utility model is based on the task of developing equipment for obtaining high-grade flour of high size, which improves the quality indicators of the finished product.

The task is achieved by the fact that in the known production line, which consistently arranged and interconnected feed hoppers for grain, equipment for primary and secondary cleaning of grain, its moistening and smoothing, grinding systems large and small with roll pairs and cupboard type screenings, screenings the first and second large and small grinding systems are equipped with sieves with a hole size of 180-200 μm, installed one below the other in the vertical sections of sieving, and the number of sieves with annym size

of cultures

it is% of the total number of screens installed in one section, with screens placed at the bottom of each sieving section.

The difference of this utility model from the closest analogue is the installation of sieves on the screenings of the first and second large and small grinding systems with aperture size of sieves 180 - 200 microns. Sieves with hole sizes of less than 180 microns and more than 200 microns do not provide a solution to the problem of flour fineness.

The difference is the presence of the number of sieves of the specified size, which should not be less than Y4 from their total number in the section. When using less than these sieves, the yield of flour of increased fineness of all varieties in the maximum volume is not ensured.

The difference is also the placement of sieves in the lower part of each sieving section.

The utility model is illustrated in the drawing, where

in FIG. 1 is a schematic general view of a production line;

in FIG. 2 - schematically shows the sifting cabinet type with the installation of sieves.

The technological line for the production of high-grade flour from grain crops includes sequentially located and interconnected feed bins 1,2,3,4,5,6, equipment for the main cleaning of grain 7, equipment for moistening and smoothing 8, equipment for additional cleaning of grain 9 grinding systems, namely: the first large 10 and small 11, and the second large 12 and small 13, as well as screenings 14, 15, 16, 17, 18 of the cupboard type. Sieves 14, 15, 16, 17, equipped with sieves 19 with a hole size of 180-200 microns. The above sieves 19 are installed in the lower part of the section of each of the sieves 14, 15, 16, 17, while the number of sieves with this size is% of the total number of sieves installed in the section. All the above equipment of the processing line is interconnected by channels 20 for transporting grain and grinding products.

Grain from consumable bins 1,2,3,4,5,6 is fed through the scales and by a pneumatic conveying system (not shown in the drawing) to the equipment for the main grain cleaning 7, then the grain is moistened and smoothed out on the equipment 8 and additional cleaning on the equipment 9 , after which the grain enters the first large grinding system 10. After grinding, the material using a pneumatic transport system through the channels 20 is fed into the corresponding sieve 14, from which a larger gathering of material is fed to the grinding for the first small grinding system And, and the screening is sent to the control screening 18. The first small grinding system 11, the second large grinding system 12 and the second small grinding system 13 are similarly operated. The screenings from the screenings 15, 16, 17 are also sent to the control screening 18, from which the finished product (flour of the highest, 1 and 2 varieties of increased size) is sent to the department of finished products for packaging or bulk sales to consumers.
