Storing and cleaning of grain
<p> Primary treatment of grain and its subsequent storage - this is the most important production processes in all sectors of the grain. Primary treatment of grain not spend your time and of course without adhering to a number of technological details of production, as losses of grain in this case can reach 20% of the crop. The whole process of primary cleaning of grain is best carried out after the grain drying and cleaning before the tab in the vault for special cleaning enterprises (complexes). The complex should contain a workshop for primary processing of grain, the emergency Department, a dryer (drying unit), the other plant for processing and cleaning of grain andof course, room for long-term and temporary grain storage. The process of cleaning the grain can be divided into three stages of processing: the first stage pre-cleaning, after the drying comes the primary treatment is the second phase and the entire period ends secondary treatment. After these stages, the grain is stored. From the above it can be concluded that the complex must have at least three workshops for cleaning grain, the most important of them is considered to be the Department of primary treatment of grain.

Let's try to examine in more detail the processing steps. The process of preliminary purification takes place in the following order. Grain is necessary to prepare the mandatory drying. During this period, the grain is cleaned from various impurities, dust, minerals, particles of earth, from poisonous plants. After this stage the grain increases the flowability and bulk is stored before sending to the dryer. As already stated, preliminary cleaning of grain is recommended immediately after harvest to avoid grain losses. The first period of production allows to increase the shelf life of the grain.

The next stage of treatment - Primary treatment of grain. Be primary treatment of grain immediately after drying. The essence of this process is that the grain is brought to the commodity reference condition, and cornmeal to prepare the next processing of grain for feed. In the process of primary cleaning of grain using a sieve, separating and other settings, in some moments resort to triera. Screening help to eliminate impurities that are not removed by the screens. One important fact is along with normal cleaning equipment. It needs to be set so that the process of primary processing of grain took place in a single pass mass.

The final stage of treatment is secondary treatment of grain and its screening. This time is needed to cook the commodity and of coarse (feed) grain for processing, thereby to bring the grain to the seed condition.

Cleaning and drying are important stages in the process of post-harvest processing. Just collected the grain mass has a high moisture content to 25% and sometimes even higher. In addition, in the present grain foreign material, moisture content can reach 45%. If to store grain in this condition, its moisture content will increase due to the redistribution of moisture between the grain weight and adulteration, which can lead to rotting of crops and the development of pathogenic microorganisms and moulds and in the cold season to his podmorazhivanie. In this regard, cleaning and drying must be carried out immediately after it was collected from the fields, not yet had time to occur moisture.
</p>
<p>
In the course of cleaning grain from the mass is removed not less than 50% of impurities after the process is completed the grain can be sent for drying. The implementation of the preliminary cleaning and drying of grain helps to reduce the humidity to a required level when it excluded the possibility of spontaneous heating of the grain mass during long storage. Well-structured cleaning and drying of the grain mass contribute to the physiological maturation of the crop, improve its product qualities.
</p>
<p> When selecting equipment for cleaning and drying of grain is necessary to pay attention to its performance, the volume of fuel consumption, safety for personnel, the possibility of automatic operation. In the process of drying grain it is important to distinguish between the grain temperature and the temperature of the drying agent, which is controlled by the operator of the dryer.
</p>
<p> For the implementation of clean grain from various impurities using a variety of equipment: screening (identify impurities, which differ from the main culture in length), compatbility, sieve separators (removes impurities which differ in width and thickness), air separator (impurities and other aerodynamic properties).
</p>
<p> the implementation of the cleaning and drying of grains allows to increase the quality of grain and products of its processing, to increase shelf life of crops and to minimize losses of grain in the mass.</p>
