Grain cleaning

Rotary cleaners, precleaners, cyclones, filters and sorting lines for cereals, seeds and bulk products

Grain cleaning to improve its quality

After harvest, grain must be separated from the impurities accumulated during threshing. Efficient cleaning helps remove light and semi-heavy waste, separate broken grains from good grain, improve the quality of the final product and protect downstream equipment. GGS offers cleaning and grading solutions adapted to cereals and different sorting requirements. Depending on the project, the installation may include MAROT rotary cleaners, precleaners, cyclones, filters or sorting lines made up of several complementary pieces of equipment.

Protect your dryers, conveyors and storage systems

Each cleaning project is defined according to the nature of the product, the level of impurities, the required throughput and the expected sorting precision. Cleaning can take place at grain reception, in a handling line or in a more complete sorting line. Through its range of precleaners, cleaners and graders, MAROT provides precise separation using a rotary screening grid, whose inclination and rotation speed can be adjusted. Sorting lines can also integrate equipment for sorting grain by size, weight, shape or visual quality.

Choose the right grain cleaning process

Depending on the application, several functions can be combined:

  • Precleaning to remove dust, husks and fine straw from the grain,
  • Rotary cleaning to separate good grain mechanically from unwanted elements,
  • Grading to separate grain according to size,
  • Densimetric sorting to sort grain according to weight,
  • Indented-cylinder sorting to sort seeds according to shape,
  • Optical sorting for the most precise sorting requirements,
  • Cyclones and filters to channel and filter the extracted particles.

Each configuration is adapted to the product to be processed, the required throughput, the expected sorting level and integration into the process line.

Grain cleaning

Our cleaning solutions

MAROT rotary cleaners

MAROT rotary cleaners use a rotary screening system to separate good grain from unwanted material. They remove light waste, broken grains and coarse impurities with adjustable inclination and rotation speed.

Key benefits:

  • Throughputs from 5 to 300 tonnes per hour depending on the models
  • Rotary screening system that mechanically separates good grain from waste

Cyclones and filters for cereals

Cyclones and filters for cereals are used to collect and manage particles extracted during the cleaning process. They help channel dust and light impurities while improving air cleanliness within the installation.

Key benefits:

  • Helps ensure cleaner air
  • Filtering areas from 20
    to more than 600 m²
  • Channels all extracted particles

Precleaner dust management

Precleaners are designed to remove dust, husks and the finest grain straw. They provide the first cleaning stage before the next steps in the process, with airflow adjustment to suit different types of grain.

Key benefits:

  • Grain cleaning with no risk of loss
  • Throughput from 40 to 150 tonnes per hour
  • Adapts to different grains thanks to its airflow regulator

Optical sorting lines

Sorting lines combine several pieces of equipment to meet agricultural or industrial cleaning requirements. Depending on the expected result, they can sort grain by size, weight, shape or visual quality.

Key benefits:

  • Full automation management
  • 3D presentation of the installation available for better visualisation
