CLEANING

Efficient cleaning to protect grain quality and processing performance

Grain cleaning is a key step in post-harvest operations. It protects downstream equipment, improves drying efficiency, enhances storage safety and contributes directly to the quality and value of the final product.

GGS designs grain cleaning solutions adapted to different products, throughputs and operating conditions, ensuring reliable impurity removal while preserving grain integrity and limiting energy consumption.

Cleaning systems designed for continuous and reliable operation

Each cleaning project is defined according to the nature of the product, the level of impurities, the required throughput and the position of the equipment within the process line. Based on these parameters, GGS selects and integrates the most appropriate cleaning technologies to ensure:

  • Consistent separation efficiency,

  • Stable throughput,

  • Protection of dryers, conveyors and storage systems,

  • Safe and dust-controlled operation.

Our solutions are designed for continuous use, even under intensive harvesting and industrial conditions.

Cleaning configurations adapted to different objectives

Depending on the application, several cleaning functions can be combined:

  • Precleaning to remove coarse and light impurities at reception,

  • Cleaning to separate good grain from broken kernels and waste,

  • Grading to sort grain by size,

  • Dust management to control airborne particles and improve site safety,

  • Optical sorting for high-precision separation.

Each configuration is adapted to the required level of cleanliness and integrated seamlessly into the overall grain handling process.

Our cleaning solutions

Marot
cleaners

Marot rotary grain cleaners are based on a proven rotary screening system with continuous movement and no vibration. They ensure efficient separation, gentle grain handling and reliable unclogging for precleaning, cleaning and grading applications.

Cyclones and filters for cereals

Cyclones and filtration systems are designed to extract dust and light particles throughout the cleaning process. They improve working conditions, site safety and dust management while maintaining stable airflow and process efficiency.

Precleaner dust management

Precleaners remove coarse and light impurities at grain reception, protecting downstream equipment and improving process efficiency. Easy to integrate into intake lines or elevator heads, they allow high throughput without limiting capacity.

Sorting lines – Optical sorters

Optical sorting lines provide high-precision separation based on colour, shape and internal defects. Using advanced cameras, LED lighting and pneumatic ejectors, they ensure consistent product quality for demanding applications.
