Machine for primary cleaning of grain
The industrial grain cleaning machine (MPCG) is designed for efficient pre-cleaning, primary, and secondary processing of all types of grain, leguminous, and oilseed crops. The equipment effectively separates large, small, and light impurities, preparing the material for further sorting or storage in agricultural facilities.
Our grain cleaning machine features an advanced double aspiration system, ensuring high-quality air separation of light dust and chaff before and after the screening stage.
Key advantages of the grain cleaning machine
The MPCG grain cleaner is built for continuous operation within modern grain processing lines and offers several critical benefits:
- Low energy consumption: optimized drive mechanisms minimize overall electricity costs;
- Quick and easy reconfiguration: fast screen replacement and simple settings adaptation for any crop type;
- Double aspiration system: high-efficiency air flow for thorough removal of light impurities;
- Reliable and durable design: high structural stability during continuous intensive operation;
- Seamless integration: perfect compatibility with complete grain cleaning lines and conveying systems.
Operating principle and design features
The grain cleaning machine processes raw harvested material by combining air aspiration and mechanical sieve separation. As raw grain enters the machine, the first air channel removes light dust, husks, and straw. The grain then passes over dynamic sieves that separate oversized debris and small weed seeds, followed by a second air aspirator for final polishing. The unit integrates smoothly into lines with fractional separators, gravity selectors, and bucket elevators.

Frequently asked questions about grain cleaning machines
? What is the main purpose of double aspiration?
Double aspiration removes light impurities twice — before sieve separation and after — significantly reducing dust emission and improving final grain purity.
? Can the machine perform secondary cleaning?
Yes. By selecting appropriate sieve mesh sizes and adjusting airflow speeds, the machine can be used effectively for secondary grain processing.
