Description

The invention relates to the food industry and can be used to prepare wheat grain for processing at flour mills.

A known line for the preparation of wheat grain, consisting of a node for cleaning wheat grain from light, small, large and mineral impurities, including an air-sieve separator, a stone sampler, a node for cleaning wheat grain from impurities that differ in geometric dimensions, including a puppet collector and an oats picker, and a cleaning unit grain surface, including a washing machine and pneumatic separator (Chebotarev O.N., Shazzo A.Yu., Martynenko YF Technology of flour, cereals and animal feed. - Moscow: ICT "Mart", 2004. - S.310-313) .

The disadvantages of the known line are the low degree of purification of the grain mass from all types of impurities, as well as the high microbiological contamination of the grain mass.

The objective of the invention is the creation of a highly efficient line for the preparation of wheat grain for processing due to the intensification of technological processes in individual nodes of the line.

The technical result is an increase in the degree of purification of wheat grain and a decrease in its microbiological contamination.

The problem is solved in that in the inventive line, consisting of a unit for cleaning wheat grains from light, small, large and mineral impurities, including an air-screen separator and a stone sampler, a unit for cleaning wheat grains from impurities, including an oat filter, and a unit for cleaning the surface of wheat grains, including a scrubber machine and an air separator, a photoelectronic separator is installed in the unit for cleaning wheat grain from impurities in front of the ovule collector, while all nodes of the line are sealed.

The drawing shows a schematic flow diagram of a line for preparing wheat grain for processing.

The inventive line consists of an air-sieve separator (1), designed to clean wheat grains from light, small, large impurities, a stone sampler (2) for separating mineral impurities (pebbles, sand, etc.) and puny grain, operational hopper ( 3), a photoelectronic separator (4), designed to isolate impurities that are different from wheat grains in color, an oats picker (5) to remove impurities that differ in length from wheat grains, a magnetic separator (6) for extracting metal-magnetic impurities from the grain mass, th machine (7) intended to clean the surface grain and sifter (8).

The inventive line operates as follows.

The grain mass entering the preparatory department of the mill is cleaned of light, small and large impurities on an air-sieve separator (1) and sent to a stone collector (2), where mineral impurities (pebbles, sand, etc.) and sloppy are released corn. Separated impurities are removed from production, and the grain mass is sent to the operational hopper (3). From the operational hopper (3), the grain mass enters the photoelectronic separator (4). The impurities highlighted by color in the photoelectronic separator are discontinued. The cleaned grain mass is sent to an oats picker (5) to isolate impurities that are different from the grain of wheat in length, and then passes magnetic protection on a magnetic separator (6) and is sent to a cleaning machine (7), in which the grain surface is cleaned. From the washing machine (7), the grain mass enters the pneumatic separator (8), from which the wheat grain, cleaned of all types of impurities, as well as with a cleaned surface, is sent for further processing - for the process of moisturizing and smoothing.

All apparatuses of the claimed line are sealed, which prevents the emission of dust from the apparatus bodies into production and into the environment.

On the claimed line was carried out experimental preparation of wheat for processing.

The table shows the data characterizing the effectiveness of the preparation of wheat grain for processing on the known and claimed lines.

Table Name of indicator Indicator value Famous line The claimed line Mass fraction of mineral impurity,% 0.18 absent Mass fraction of fusarium grains,% 0.55 absent Mass fraction of cockle,% 0.32 absent Mass fraction of harmful impurities,% 0.12 absent Total microbiological contamination, CFU / g 30.2 × 10 ³ 12.0 × 10 ³

From the data given in the table it can be seen that wheat grain prepared for processing on the claimed line has a high degree of purification from all types of impurities, as well as low microbiological contamination compared to wheat grain prepared for processing on a known line.
