Secondary & seed cleaning

Specific requirements are placed on seed grain cleaning equipment, as long as poor cleaning, drying and storage of seeds causes unplanned losses for the next year in the amount of 9% at all stages.
"MELINVEST" OJSC has developed a range of equipment for high-quality seed cleaning.

Trieur Blocks

Trieur blocks are meant for separating impurities which differ in length from the basic crops. Trieur block separates short impurities (corn cockle, buckwheat and cracked grain) and long impurities (oat grass and straw).

Basic operating elements of the trieur block are the trieur cylinders which can operate both as a whole and separately.

Trieur Block Peculiar Features

  • Low energy consumption in comparison with analogues — 1,5 kW/h per 1 cylinder
  • An individual drive for each cylinde
  • Quick change of trieur platin
  • Construction simplicity, which means equipment reliability

Concentrators

Concentrators are meant for grain grading by unit weight, size and density at grain storing and processing plants.

Grain can be sorted by grade due to boiling bed creation by means of vibration and air flow.
