As you know, peeling (debraning) is an effective technique in the preparation of wheat for quality grinding. Using the process of scaling can significantly reduce the ash content of grain, reduce the content of trash, and create favorable conditions for air conditioning. Increasing the total yield of flour from flour of high grades is a natural result of the preparation of grain for milling with the use of peeling. 
      It is now widely used reporting method finds in mills of small and medium capacity (up to 100 tons per day.). These mills are usually created by the reduced schemes, providing they are not the high cost of development and operation. However, these advantages are provided by using a very limited fleet. Therefore, the application of scaling to these mills, very often, is the only possible and economically justified measure to ensure the efficiency of grinding.

Separation is one of the most important operations in the cultivation, storage and processing of grain. The degree of purification and classification of seed in many ways affect the crop. The degree of separation of the grain piles after harvest determines the stability of grain quality during storage. Cleaning grain to flour and cereal plants determines the quality of the finished product. Selecting the method of separation depends on the core topics differences particles of components that must be divided. However, in any case, any grain necessarily be cleaned in a sieve, air separators, consisting, respectively, from the air and sieve separators. When cleaning in the air separator air flow, blowing seed, takes light impurities. Thus, the grain is separated from the main part of the stems and ears of corn, chaff, weed seeds, a frail, eaten by pests of grain, dust, etc. Sieving grain mass separators in sieving on sieves provides separation of the geometric dimensions (thickness and width). Since the grain is cleaned of major and minor impurities, as well as calibrated by fractions size. On a design major working organs sieve separators are divided into cages with flat or cylindrical screens. In turn, the cylindrical screen can be made in the form of vertical sieve cylinders or horizontal sieve drum. 

Some agro-industrial enterprises and holding companies, having succeeded in matters of grain production, seeking to establish or expand its recycling. Often in their field of view falls mill production to develop a variety of wheat flour. Our observations show that most leaders, mastered this new form of business for themselves, prone to mistakes in choosing effective means to implement it. Flour production is characterized by profound specificity, going far beyond the tales of managers on the sale of a manufacturer. In this article we will still try without much introduction into the technological aspects to clarify at least the basic organizational and technical approaches to creating a successful mill production.

As is known, the moisture content of grain and grain products is a key indicator of their quality. Moisture acts medium for biochemical reactions and other transformations that define the behavior of grain and its anatomical parts in any process. Therefore, storage, movement of grain and all kinds of its processing are inseparably linked with the need to determine the moisture content.
      There are two methods of moisture determination: direct and indirect. Direct methods based on the removal of the sample in any way water and measure the mass of the sample before and after its removal. Indirect methods of measuring humidity based on changes in the physical, electrical, chemical, and mechanical properties of grain and grain products, depending on their moisture. Naturally, that direct methods are more accurate, but for the implementation of indirect methods require much less time. Due to these advantages, demand is equipment, for both direct and for indirect methods. Therefore, the market of laboratory equipment offered a large variety of ovens, stoves, moisture meters, analyzers, etc. However, in all countries of the CIS unified and standardized laboratory method for determination of moisture is the air-heat method, implemented in accordance with GOST 13586.5-93. This method is the only recognized method of determining moisture, used at calculations for all operations with the grain.

With the coming cold season in most mills are visible problems associated with a decrease in the quality and yield of flour. The main reason for this decline is a violation of the temperature conditions necessary for the effective conduct waterthermal  grain handling. 
      As you know, waterthermal processing of grain, also known as air-conditioning, along with cleaning, form the basis of training in wheat quality grinding. In the process of conditioning under the influence of moisture and heat directionally changing the physical and mechanical properties of grain. Shell becomes more robust and resilient, and endosperm loses its strength and becomes friable. Such changes are a result of grinding flour contributes to increasing output and reduce its ash content, improve whiteness. As a result of biochemical processes that accompany the air conditioning in the flour produced better quality of gluten, increases the activity of enzymes.

Task of improving the quality and yield of flour remain valid for the majority of mills grinding wheat cultivar that requires a search for secure and economically viable solutions. One of the directions of this search is to use the processing of grain on the stages of its preparation for the meal, known abroad under the term «debraning». Debranning - derived from the word «bran» (bran), which can be translated as scales, respectively, a car, to implement the process scaling,  peeler, called «debraner» (debranner).

 Recent years, much of the flour produced in mills with low productivity. These include the mill capacity of 25 - 60 tons / day grains with reduced quality grinding circuits. 
        The main feature of the mills of this type is to use "short" circuits grinding grain, consisting of 8, 6 or even 4 systems. Providing a high yield of flour in such schemes require a significant amount of its recovery in torn processes, which is achieved by maintaining low mode grinding. Such regimes is usually characterized by not high quality flour for chopping hulls of grain, as well as penetrating into the large part of the impurities contained in the grain. Moreover, the low modes to a minimum reduces the number of pellet, and thus a higher quality flour that is obtained by grinding processes. It is quite clear that the shortage clot enrichment process can not significantly change the overall balance of flour to higher grades and in most of the schemes available. Thus, the current controversy quality output of flour at mills of this type are insoluble in the grinding of their offices. Effective solution to this problem is connected with the need to significantly improve the quality of flour in torn processes and, as experience shows, is ensured by the higher requirements for the preparation of grain for grinding. These include not only a thorough cleaning and bringing grain in the best condition for grinding through conditioning, but also to make substantial progress to reduce its ash content. Successful completion of the task is aggravated by the specific conditions of low-capacity mills, which include limited resources, communications, and working space and, hence, limited opportunities for used fleet.

As you know, in the training of grain breakage is traditionally used hulling machine. Their task is to clean the surface of grains of sticky dust, sand and microorganisms, removal of the upper torn amniotic membrane, as well as the removal of beards and partial embryo. Evaluate the efficiency of hulling machines to reduce the ash content of grain as a result of treatment. Hulling machine is called effective if they work reduces the ash content of grain by not less than 0.03%, while the increment of the number of broken grains is less than 1%. Considered to be: if the total reduction in ash content of grain after the grain-cleaning of all operations in the range 0.07 - 0.011%, the cleaning in general performed efficiently. Given that the traditional patterns of grain-cleaning in mills contain two sequentially mounted hulling machine, we can conclude that the effectiveness of these machines depends essentially the result of the overall grain-cleaning. 

In the article "Efficient processing - the main factor promoting of soriz" (Journal Storage and Processing ", # 1, 2002), we have presented problems in grain production from corn of soriz, solutions and results. However, some portions of this study will gain a deeper extension and wider use, because affect the basic processes of processing of other cultures. By such processes include the operations peeling, grinding grain, conducted mainly in machines abrasive impact. Understanding the set of actions to develop cereals as purposeful redistribution of anatomical parts of the grain, gives grounds to consider the processing of its surface as one of the most powerful tool for influencing the efficiency of production as a whole. Contained and is the main argument, confirming the relevance of the material presented below.
