The Intelligent Combined Pre-Cleaner is an advanced grain cleaning machine designed for high-efficiency pre-cleaning in modern grain processing plants. It integrates multiple cleaning functions—including air separation, vibrating screening, and gravity separation—into a compact and intelligent system. This machine is capable of removing large impurities such as straw and stones, as well as light materials like husks and dust, in a single operation.
Equipped with smart control systems, the pre-cleaner allows for automatic adjustment of air volume, screen vibration, and feed rate based on grain type and contamination level. Sensors monitor operation status in real time, reducing manual labor and ensuring consistent cleaning performance. The modular design supports easy maintenance and flexible configuration for different cleaning tasks.
Made from high-strength materials with anti-corrosion treatment, the Intelligent Combined Pre-Cleaner is durable and suitable for continuous operation. It is ideal for large grain depots, flour mills, and seed processing lines where efficiency, automation, and reliability are key.
HOW DOES THE AIR SCREEN CLEANER WORK
The air screen cleaner works by combining two main cleaning methods: mechanical screening and air separation. First, raw grain is loaded into a feed hopper and distributed evenly onto vibrating screens. These screens have multiple layers with different mesh sizes. As the grain moves over the vibrating surface, larger impurities like straw and stones are removed on the upper screens, while smaller particles such as dust and sand fall through lower screens. Only grains of the correct size pass through to the next stage.
After the screening process, the partially cleaned grain enters the air separation section. A strong airflow generated by an aspirator or fan passes through the falling grain. Light impurities like husks, chaff, and dust are blown away by the air and collected in a dust chamber or filter system. The cleaned, heavier grain drops into a collection bin or discharge outlet.
This two-stage process ensures high-quality cleaning of seeds and grains, making the air screen cleaner an essential machine in grain processing plants and agricultural industries.
WHAT ARE THE DIFFERENT TYPES OF AIR SCREEN CLEANERS
There are several types of air screen cleaners, each designed to meet different cleaning needs and capacities in grain and seed processing. The most common types include basic air screen cleaners, vibratory air screen cleaners, and combined air screen cleaners.
Basic air screen cleaners use a simple system of vibrating screens and an air aspirator. They are ideal for small to medium-scale operations and can remove both large and light impurities effectively.
Vibratory air screen cleaners include enhanced vibration mechanisms for better material movement across the screens. They offer higher capacity and improved precision, making them suitable for commercial seed processing and grain mills.
Combined air screen cleaners integrate multiple functions, such as screening, aspiration, and gravity separation, into one machine. These are used for pre-cleaning and fine cleaning in large-scale industrial facilities. They often feature adjustable airflow, automated controls, and modular designs for high efficiency and flexibility.
Some models also come with intelligent features, like automatic air and vibration adjustment, dust collection systems, and real-time monitoring. These variations help users select the right machine based on grain type, impurity level, and production volume.
