Description

(54) DEVICE FOR SEPARATION OF FLOUR BY PROTECTION OF PROTEIN

. . . .one

FIELD OF THE INVENTION The invention relates to the food industry, namely to the milling industry.

A device for the separation of flour according to the protein content, containing two coaxial pipes, a loading nozzle, a regulating device and a collecting bin with a bolt, is known.

However, the known device has a low productivity and does not provide complete separation of the flour by protein content.

Closest to the present invention, there is a device for separating flour according to the protein content, containing vertical pipes coaxially arranged one into another, externally of which has a tangentially located feed inlet and collecting bun. ker 2.

However, this device does not provide the required quality of separation of the skin and has insufficient production.

capacity, which reduces the number of fractions obtained,

The purpose of the invention is to increase the quality of the separation of flour, as well as increase the number of fractions.

This goal is achieved by the fact that in a device for separating flour by protein content, containing three coaxially arranged pipes into one another, externally of which has a tangentially located feed inlet and collecting hopper, the pipe installed between the inner and outer pipes is provided with an additional inlet pipe located similarly to the outer pipe nozzle, while the diameters of the pipes and nozzles are selected so that the cross-sectional area of the inner pipe, the "nozzle and the gap between the pipes are equal.

Fig. 1 shows a device for separating flour according to its protein content, a general view; Fig 2 - the same, side view.

A device for separating flour according to the protein content contains three vergical coarse 1-3 coaxially arranged one into another, externally which have a gangeitially located loading nozzle 4 n collecting hopper 5, with coarse 2 being installed between the oil pipe and the inner pipe I and 3 , is equipped with an additional pipe 6, located similarly to the pipe of the external pipe I, while the diameters are coarse I – 3 and the pipes 4, 6 are chosen so that the cross-sectional area of the internal pipe 3, pipes 4, 6 and the gap between the pipes 1-3 are equal. The device works as follows. Flour through pipe 4 enters the cavity between pipes I and 2, where the spiral movement of the mixture relative to the pipe occurs. 2. Due to inertia, the air flow moves sirically along pipe 2 to the end wall of the strip. In this zone, the product is separated, the coarse fraction is released into the collecting hopper 5, and the fine and medium fractions are sucked into the pipe 3 where. through the additional nozzle 6, air is sucked from the atmosphere, which draws from the middle zone of the vortex flow the product particles with medium and small mass at the entrance to the pipe 3, which contributes to intensive suction of the small and medium fractions for its subsequent separation and ensuring posledukitsee an effective separation. The change in the amount of air leaks in the pipe 6 into the pipe 3 regulate the amount of sucked small; medium fraction and recovered coarse fraction in the hopper 5. Separated fractions are removed from the device, the proposed device provides high-quality separation of flour, which provides high-protein fraction of flour with a particle size of 15 µm and below, allows rational use of protein resources of wheat grain when This proposed device has high performance. Apparatus of the invention for the separation of flour according to the protein content, containing three coaxially arranged pipes into one another, externally of which has a tangentially located feed pipe, an assembled biker, characterized in between the inner and outer pipes, provided with an additional pipe located similarly to the pipe of the external pipe, while the diameters of the pipes and pipes are chosen so that the areas are crossed The internal section of the inner pipe, the pipes and the gap are equal to the pipes.
