Definitions

  • the proposed technical solution is one of the flour production processes Cereal products in which the components of the cereal body differ significantly Have strength and other physical-mechanical characteristics. You (the solution) can for that Variety and wholemeal flour production, e.g. from wheat, rye, barley, oats, corn etc. used will.
  • the process of making flour from cereal products has a difference from the known ones
  • the process of grinding materials has its own specific characteristics.
  • One of the The main peculiarities of grinding are the selectivity of the grain decay, e.g. the glume or the Final sperms in the wheat.
  • the quality of the finished product is determined by the degree of selectivity of the Glume and final sperm decay in relation to wheat determined and as known by the Parameter ⁇ ash content ⁇ expressed.
  • the ash content index of the flour rises steeply, and its quality drops significantly.
  • the analog of the proposed method is the method of making flour using rotatable tools in the form of a beater or disc rotor with respect to the immovable Feeding, which is ribbed or sieve-shaped, the (the process) in the mill operation for the Increase the degree of grinding of the variety flour is used.
  • the present procedure is in the Grinding machines, Entoleitoren and dissolvers realized that the replacement of the Ensure the final sperm grain residues from the glume (1) that have grown with it.
  • the working principle of the above-mentioned machines is mainly based on the selective disintegration of the Starting product through the impact thrust loads.
  • the impact of impact shock loads leads to an intense one Over-grinding and consequently to increase the ⁇ ash content ⁇ in the flour (i.e. to lower it Quality).
  • the detachment of the final sperm grains from the glume after the process analog is one additional work grinding operation that complements all of the grinding operations of the Variety flour heard in the mill. In this way, the process analog of flour production not be used independently for type flour flour milling.
  • the prototype of the proposed technical solution is the process of making flour Grain products using the roller mills (2).
  • the production of the flour is after present method by the selective disintegration of the grain components in the contact zone of the rotatable tools - the roller-shaped grinding media and by the subsequent sorting of the Grinding products executed according to the degree of grip and the composition.
  • the rotation of the with Rolls contacting the grain are usually made with different ones Circulation speeds and the working surface of the rollers are corrugated and micro-rough.
  • the gap between the rollers when grinding different products in the roller mills fluctuates within relatively wide limits (from 0.05 to 1 mm).
  • the grain decay runs in the Roller mills due to the thrust and pressure loads.
  • the deficiencies of the process prototype include the low degree of grinding of the variety flour the grinding of the cereal products for a stitch in the roller mills as well as of the grist, as also of the grinding type, e.g. not more than 10-15 percent of the first variety. This is explained by that the selectivity of grain decay is significantly reduced due to the presence of a significant part of the decay loads on the grain caused by different Circulation speeds of the roll rotation are conditional. That's why you use in the Production line for the production of the high degree of grinding of the type flour in the mill operation Complex of crushing machines made up of a few tens of machines from the grist, Grinding and grinding types exist.
  • the technical result of the proposed solution is to increase the degree of grinding of the Variety flour for a stitch of the grain product through the shredder and also the Reduction of the metal intensity of the equipment from the production line to the production of the Variety flour and energy expenditure for your work.
  • the technical result is achieved by using the known flour production process from grain products, which the decay of the grain constituents with the help of the grinding rotating body and the subsequent sorting according to the degree of grip and the composition includes selective disintegration of the cereal products by rolling the grain, which is aligned with the support surface puts on, with the help of the grinding rotating body, the comminution of the grain parts, and the final sperm and the husk, to be detached, and the grinding of the cereal products leads one mainly by the pressure contact loads of the grinding media on the grain in the Grain product run from onset to seizure, thereby reducing the pressure contact loads on the Grinding media on the grain in stages in the same direction.
  • the pressure contact loads of the grinding media on the grain e.g. through the curvilinear Conversion of the grinding media along the curvilinear support surface
  • you regulate the size of the Pressure contact load of the grinding media on the grain by changing the mass of the grinding media or its linear exit velocity along the support surface, or [by the change] of the Size ratio between the half-knives of the support surface of the grinding media and the half-knife of the supporting work surface, and the grinding rotors are set in with the gradually removable gap with respect to the support surface in the direction of the grain product run from onset to onset.

  • the pressure loads settled on the grain upon decay.
  • the pressure loads are compared to the Shear loads and shear stresses, such as practice and investigations carried out show a significant increase in selectivity of the decay of the grain constituents, i.e. the glume and of the final sperm, sure. This is due to the difference in physical-mechanical properties the grain components achieved: strength, brittleness, toughness, elasticity etc.
  • the change to the side of the decrease in the gap size between the Working surface of the grinding media and the stationary support surface in the present method on the Initial stage of the grain grinding does not involve its (the grain) decay through a stage deformation large sizes of its deformation and accordingly with reduced contact loads of the Execute grinding media on the grain.
  • the reduced contact forces of the grinding media on the grain and relatively small amounts of its deformation in turn contribute to the substantial reduction in the Grain disintegration when grinding the cereal products according to the proposed method.
  • the proposed method significantly increases the degree of grinding due to the implementation of the entire complex of the above handles of the selective disintegration of the cereal products in the Grinding.
  • the state surveys carried out on wheat grinding after present methods have the possibility of increasing the degree of grinding to three-four times shown, compared to the grinding of the identical wheat by the roller mills a one-time stab of the product by a roller mill.
  • the increase in the degree of grinding According to the proposed method, the metal and Energy intensity of the production line for the production of variety flour from grain products the essential reduction in it (in line) - on the multiple of the crushing and Lower sorting machines.
