Industrial Pneumatic Coffee Destoners (30 to 120 kg)

Eliminate field stones, metallic debris, and dense contaminants from roasted coffee batches before grinding and packaging. High-vacuum pneumatic fluidization, rare-earth neodymium magnetic traps, and acoustic sound dampening.

DE Series Pneumatic Fluidization Destoner Lineup

RC DE-30: 30 kg batch capacity (3–4 min cycle, 450–600 kg/h). Compact commercial destoner matched for CAST-5 and CAST-15 roasteries.

RC DE-60: 60 kg batch capacity (5 min cycle, 720 kg/h). Wholesale commercial workhorse paired with CAST-30 and IS-60 production lines.

RC DE-120: 120 kg batch capacity (8 min cycle, 1,000–1,200 kg/h). High-tonnage industrial platform integrated with IS-120 and roasted silo conveying lines.

Engineering & Grinder Protection Technology

Density Fluidization Separation: Exploits the difference between expanded roasted coffee bulk density (350 g/L) and field stone density (2,500+ g/L) with 99.9% separation accuracy.

Neodymium Rare-Earth Magnetic Traps: In-line magnetic grid traps ferrous wire, nails, and metal shavings that cannot be caught by airflow alone.

Zero Bean Breakage: Wide-radius sanitary stainless steel transport tubes moving beans below 4 m/s prevent bean chipping and preserve whole-bean visual aesthetics.
