Grain pre-cleaner AS series

for maizewith cyclonefor samples

Overview The ASU and ASA air pre-cleaners perform intake pre-cleaning for bulk agricultural and food products, removing dust, light particles and coarse impurities upstream of drying, storage and processing equipment. Designed for grain handling (grain, corn, malt), they offer separate discharges for dust and light fractions to improve plant hygiene and downstream equipment performance.

Key benefits

• Reduce airborne dust and lower the risk of dust explosions by extracting light particles before they spread in the plant.
• Discharge screws remove dust and light fractions prior to the filter stage, reducing filter clogging and extending filter service intervals.
• Adjustable configuration for different products (grain, corn, malt) enables more precise pre-cleaning and consistent throughput.

Highlight features

• Two configurations: ASU (recirculation) uses a smaller cyclone and less filter surface for equivalent throughput; ASA (exhaust) handles dusty or oily products via exhaust air.
• Compact footprint and cost-effective design; a vibrating distribution flap evens product feed to increase throughput.
• Integrated discharge screws remove fines before filtration and permit sampling from the discharge piping.
• Optional wear protection for abrasive products and continuous 24/7 operation.
• Enclosed construction to limit dust emission and improve sanitation in reception and processing areas.

Applications and use Intended for intake and pre-cleaning of bulk cereals and feed/food products such as grain, corn and malt. Typical use cases include reception lines, cleaning and aspiration stages upstream of dryers, silos and milling or malting equipment.

Typical integration Separate discharge outlets allow connection to downstream cleaning and screening machines (e.g., drum sieves, universal cleaners). The unit is commonly placed in intake/reception and cleaning chains within grain handling and processing plants to protect downstream equipment and improve product quality.

Specifications / technical data

• Models: ASU (recirculation) and ASA (exhaust air).
• Function: removal of dust, light particles and coarse impurities; separate outlets for dust and light fractions.
• Filtration strategy: ASU requires a smaller cyclone and less filter surface for equivalent throughput; ASA uses exhaust air suited to dusty or oily products.
• Discharge screws included to reduce filter load and enable sampling.
• Design: compact footprint with vibrating distribution flap for even product spread.
• Options: wear protection for abrasive products or continuous operation; enclosed construction for improved sanitation.
• Intended products: grain, corn, malt and similar food/feed products.
