Grain-cleaning machines ALFA


Зерноочистительная машина Альфа 2

Grain cleaning machines ALFA 100 (as well as 50, 150, 200, 300, 400 t/h) are separators for preliminary cleaning of legumes, cereals and grain from impurities. This grain pre-cleaner of high capacity is distinguished by excellent technical and operational characteristics — it is easy to maintain, it has a relatively low cost, and it is intended to be operated in stationary production lines in any climatic zone of Russia and all over the world.

Description of the grain cleaning machine ALFA (50, 100, 150, 200, 300, 400 t/h)

This is a highly-efficient agricultural unit, which is able to clean the grain heap quickly from impurities and at the outlet to give out completely cleaned grain of commercial quality ready for further processing.

The operation of the unit is based on the aerodynamic principle of grain separation from impurities. The main machine working members are: gear motor and electric motor, cleaning module and air-cleaning section. The grain heap coming from the field is supplied to the storage bin through the grain pipes, after which it is distributed and sent to the screen conveyor. Impurities (ears, weeds and other residues) are retained and removed in the separator. Then the semi-refined product is divided into flows and passes to the aspiration channel. Light impurities are separated by means of the forced air and completely cleaned grain is discharged by gravity.

Advantages of grain cleaning machines ALFA:

  • High processing speed — with the correct settings, the unit can clean up to 9,2 thousand tons of grain per a day.
  • Cost-effective and at the same time reliable electric drive.
  • There are no belt drives in the mechanisms, due to which there is no need for constant adjustment of separate assembly units of the machine.
  • Uniform distribution of the grain flow at all stages of grain processing.
  • Ability to improve the functional features of the machine by means of installing additional modules.
  • Easy maintenance — the unit is easily and quickly prepared for cleaning of various crops.
  • Multi-functional performance of wheat cleaner — the possibility of fine adjustment of the air flow for products with different impurity and humidity levels.
  • Due to its overall dimensions the machine is space-effective, as ALFA 50, for instance. Our customers sometimes call it as mini wheat cleaning machine. If you are interested in mini wheat cleaning machine price, please contact us.

In addition to this, the body and all driving units of grain cleaning machine are made of high quality galvanized steel, which prevents product from sticking, provides an anti-corrosion effect and increases the service life of the machine in any climate. The machine has high capacity and a whole host of positive qualities. It has multi-functional performance, which means that this is possible to adjust the air flow for grain products with different impurity and humidity levels. Every farmer will be glad to have such an assistant in his farm. The machine body is made of high quality galvanized steel for maximum corrosion resistance and longer service life in any climate zone. Bolted units of the machine prevent deformation during its shipment, installation and operation.

Before the introduction of this grain pre-cleaner there were other models that could not boast of their flexible configuration and capacity.

But the main advantage is easy maintenance of the machine. It is very important after a hard working day to clean hard-to-reach places and prepare the machine for cleaning of other crops without any efforts.



Scheme of operation of grain cleaner

The main working members of the machine are: cleaning module 2 and air cleaning section 3. The working members are driven by gear motor and electric motor. The grain heap enters the storage bin 1, where the material is accumulated and uniformly distributed along the machine and is fed by means of 4: ALFA 50, ALFA 100 — flow control valves; ALFA 150, ALFA 200, ALFA 300, ALFA 400 — beaters. The screen conveyor consists of the screen 7, a driving shaft 5 and a driven shaft 6. The tension of the screen sieve 7 is carried out by moving of the driving shaft by means of tension bolts and is determined by the chain slack.
Grain, light and fine impurities pass through it and coarse impurities (straw, ears, etc.) are discharged from the machine by the screen conveyor 8 throught the outlet bin 9.
The material, passed through the screen conveyor 8, is divided into two flows 10. Then the product passes through the blockage sensor 17. The closed air flow is produced by a built-in cross-flow fan 11. The air flow rate is regulated by a flap valve 12 located in the pressure channel 13. Light impurities are discharged by the valve 14 with adjustable load weights 16, and the cleaned grain is discharged by gravity flow 15. For maintenance and cleaning of the air-cleaning section 3, there is also a special hatch 18 provided.
