Description

VORTEX GRABBREAKER OF GRAIN MATERIALS

The utility model relates to devices for peeling (removing shells) grains of various crops and can be used in 1-step production.

Known devices for peeling with disk, cylindrical or deck working bodies 1.

The disadvantage of these devices is that they do not prevent mechanical damage to the grain.

Also known is the shell for grain materials, the working body of which is the air duct, made in the form of a zigzag channel of rectangular cross section, the inner side surfaces and concave sections of which are covered with an emery mass 2.

A disadvantage of this device is also a large percentage of the destroyed grain due to mechanical damage.

The objective of the utility model is to eliminate mechanical damage to the grain during the peeling process.

The essence of the utility model is that in a vortex scrubber of grain materials containing a feeder, an air duct and a receiving chamber, the air duct is made in the form of a vortex ejector., Which includes a tangential crossbar and diaphragm installed at the input, and a diffuser at the output.

The drawing shows a diagram of this vortex scrubber of grain materials.

supply of grain 1 and air duct., made in the form of a cylindrical vortex ejector 2, including tangential joint 3, diaphragm 4, through which the grain enters the vortex ejector, and diffuser 5 to reduce the speed of the air flow and reduce the distance of departure of grain. A receiving chamber 6 with a nozzle 7 is connected to the exit of the vortex ejector for supplying a separating air stream. The receiving chamber 6 has a hopper 8 for collecting the exfoliated kernel of grain and a lock gate 9 for outputting it, as well as a hopper 10 for collecting the removed films and a lock gate 11 for their exit & For the air outlet, the nozzle 12 is used. For regulating the clarity of the air separation of the core and the film in the receiving the chamber has a rotary valve 13.

The work is as follows.

When air is supplied from the compressor to the tangential nozzle 3 of the vortex ejector 2, the air flow moves in a spiral, because of which a low pressure region forms along the axis of the ejector. As a result of this, the grain is sucked from the feeding feeder 1 and enters the vacuum region. Due to the sudden pressure inequality under the shell of the grain, equal to atmospheric, and outside the grain equal to the pressure in the vortex ejector, the shell breaks and thus a peeling process is carried out, eliminating damage to the grain. The diffuser 5 reduces the speed at which the core and film of grain enter the receiving chamber, thereby reducing the distance of their departure. The final separation of the core and the film is completed in the receiving chamber 6 by a stream of air. Incoming through nozzles 7 (into which air also comes from the Comfessor) and crossing the stream of peeling products in flight. The core flies into the hopper 8 and is discharged through the lock gate 9, and the films are entrained by the air stream and enter the hopper) 10, from which they are discharged through the lock gate 11. The air separation of the core and the film is about (can be detected by turning valve 13.

According to this technical solution, a prototype was manufactured and tested. Tests have shown that, compared with the prototype, the inventive utility model while maintaining the same productivity provides high quality exfoliated grain by eliminating mechanical damage during peeling.
