Crop cleaner AS series

Overview
The ASU and ASA air pre-cleaners remove dust and light particles from grain, corn, malt and other food products. They provide separate discharge outlets for dust and light particles and help reduce airborne dust and the associated explosion risk in reception, drying and storage operations.

Key benefits

• Reduce dust and improve plant safety: ASU and ASA extract dust and light particles upstream to lower the risk of dust explosions and to protect downstream equipment.
• Discharge screws for pre-separation: Discharge screws evacuate dust and light particles before the filter, preventing clogging and extending filter service life. Discharge piping is accessible for sampling.
• Adjustable cleaning for product type: The pre-cleaner can be configured for the handled product (grain, malt, corn) to achieve targeted pre-cleaning.

Highlight features

• Air flow / Differences between ASU and ASA: ASU uses a recirculation system, requiring a smaller cyclone and less filter surface for equivalent throughput. ASA operates on exhaust air and is better suited to dusty or oily products.
• Compact footprint with high throughput: Compact design with a vibrating distribution flap that spreads the product evenly to increase throughput.
• Prolonged service life: Optional wear protection is available for abrasive products or continuous 24/7 operation.
• Sanitary, enclosed design: Enclosure prevents dust ingress into the plant and improves sanitation while reducing dust emissions and explosion risk.

Application note / testimonial
At crop reception points (for example corn), the ASU pre-cleaner removes light particles and dust before drying and storage. In combination with downstream screening, only thoroughly pre-cleaned material proceeds to dryers and silos, improving dryer efficiency and storage quality.

Technical specifications

• Suitable for: grain, corn, malt and other food products.
• Separate discharges for dust and light particles.
• Two principal types: ASU (recirculation system) and ASA (exhaust air system) — ASU: smaller cyclone and less filter surface; ASA: suited for dusty or oily products.
• Discharge screws to remove dust and light particles; discharge piping accessible for sampling.
• Compact footprint with vibrating distribution flap for even product spread and increased throughput.
• Optional wear protection for abrasive products and continuous operation (24/7).
• Enclosed design to improve sanitation and reduce dust emissions and explosion risk.
• Designed to prolong filter lifetime by removing dust before it reaches the filter.
