Description: Mounted above packing beds or between packing‑bed segments inside corn‑starch washing towers. Uniformly spreads incoming starch‑slurry and circulating wash‑water over full tower cross‑section. Eliminates channeling, wall‑flow and flow‑maldistribution phenomena, securing sufficient liquid‑to‑Pall‑ring / Step‑ring‑packing contact. Enhances mass‑transfer washing efficiency, improves removal rates for protein, fine‑fiber and other impurities and stabilizes starch‑washing product‑quality plus unit throughput capacity.
Core has. Starch-process anti-clog design: Large-orifice liquid-distribution holes or overflow-weir geometry with generously-sized open flow-paths.
Not susceptible to blockage from starch-granule/fine-fiber loading for continuous solids-bearing-media service.
Uniform stable liquid dispersion: Multi-stage flow-splitting architecture; liquid-dispensing points fully cover tower cross-section with minimal liquid-level deviation.
Maintains good distribution performance even under feed-flow fluctuations, granting broad operating turndown range.
Food-grade hygienic design: All wetted parts are 304/316L food-grade stainless-steel; smooth burr-free surfaces without material-accumulation dead-spots, complying with food-processing-hygiene standards.
Robust erosion-resistant mechanical construction: Full-welded construction with reinforcing support members; withstands feed-stream impingement and tower-internal vibration.
Maintains geometry without deformation or positional-shift through long runtime.
Installation-and-maintenance-friendly: Modular-split-assembly design permitting on-site field assembly; convenient hoisting into tower for inspection-and-cleaning operations, lowering maintenance-cost and downtime-loss.
Structural composition. Primary feed-distribution header/main trough: Receives incoming tower-feed and first-stage coarse flow-splitting.
Distribution branches/secondary troughs: secondary uniform flow-distribution and convey fluid to individual dispensing locations.
Liquid-distribution orifices/overflow-weir notches: Final stage to spread liquid evenly onto underlying packing-bed.
Support-and-mounting frame: For in-tank positioning, mechanical support and horizontal-level calibration.
Fastener hardware: Standard stainless-steel components for modular-segment joining and fixationMainstream structural types (commonly used in starch washing towers)
1. Trough-type gravity liquid distributor (weir-flow style): Constructed of primary main trough plus multi-level secondary distribution troughs.
Gravity-driven overflow liquid dispersion; wide operating turndown ratio, excellent anti-clogging performance and high liquid-distribution uniformity.
First-choice hardware for large-/medium-diameter corn-starch washing-towers especially well-suited for coarse-wash sections with high fine-fiber and starch-particle loading.
Pipe-and-header liquid distributor: Composed of main supply header plus multiple parallel branch pipes drilled with liquid-dispensing orifices.
Simple construction, high volumetric-flow capacity and cost-effective manufacturing. Applied for small-medium-diameter washing-towers or refining-section duties.
Can be manufactured in annular or parallel-pipe layout adapting to varying tower-internal-diameter dimensions.
