Grain Cleaning Plants

Multi-stage cleaning to bring grain from raw intake condition to finished specification.

Multi-stage cleaning sequences using pre-cleaners, aspirators, destoners, gravity tables, and graders to produce clean grain at finished specification. Plant design is matched to the incoming grain condition and the target output standard.

Facet Engineering grain cleaner pre-cleaning system

Facet Engineering grain cleaner in a pre-cleaning configuration: aspirated scalper removing gross contaminants ahead of the main cleaning sequence

01 / 11

Overview

A grain cleaning plant sequences multiple separation technologies to progressively remove different categories of impurity from the raw grain stream. The cleaning sequence is designed around the incoming grain condition and the target output specification. Typical cleaning stages include pre-cleaning (gross removal), aspiration (light material), destoning (heavy material), screening (size separation), and gravity table (density separation). For seed production, length graders and electronic colour sorters are added to achieve germination percentage and purity standards. Facet Engineering designs the full plant including conveying between machines, dust extraction throughout, and final routing to storage or bagging.

Typical Plant Scope

Pre-cleaner for gross foreign material removal
Aspirators for light material and dust removal
Destoner for stone, sand, and heavy contaminant removal
Grading screens for size separation

Typical Applications

Export grain cleaning to specification
Certified seed cleaning and upgrading
Milling plant raw material cleaning
Feed ingredient preparation
