Why Tubular Drag Chain?

Stainless or hardened‑alloy chain with molded discs gently moves product inside sealed tubes—minimizing breakage, segregation, dust, and contamination while enabling long, complex routing.
  • Near‑zero product breakage and excellent blend integrity.
  • Dust‑ and gas‑tight tubes protect product and environment.
  • Any direction: go horizontal ↔ vertical with multiple inlets/outlets.
  • CIP tiers from dry clean‑out to fully automated wet wash and dry.
  • Food‑grade design: FDA‑approved discs, flanged connections, pass‑swab sanitation.

Conveying Capacities

Actual rates depend on product, chain speed, layout, and disc selection. Typical ranges below:

Tube Size Indicative Capacity* Common Uses
3"Up to ~175 ft³/hrMalted barley, seeds, crumbs
4"Up to ~650 ft³/hrCoffee (green/roasted), oats, nuts
5"Up to ~1,000 ft³/hrPet food, cereals, peanuts, cashews
6"Up to ~1,400 ft³/hrLarge‑scale ingredient transfer
8"Up to ~2,000 ft³/hrHigh‑volume baking/brewing systems

*We confirm rates with testing and layout modeling.

Sanitation: Clean‑In‑Place Options

  • Tier 1 – Dry Clean‑Out Air knives, brush box (static or powered), and clean‑out discs to eliminate carryover.
  • Tier 2 – Hybrid Wet/Dry Spray nozzles, drains, drying ports, and clean‑out access; semi‑automated sequences.
  • Tier 3 – Full Wet CIP Flanged piping, full‑CIP turnarounds & drive units, automated cart (rinse, wash, sanitize, dry), HEPA hot‑air drying.
Passes strict food‑industry swab tests (ATP, APC, Coliform, bi‑luminous). CIP integrates with existing plant skids or dedicated mobile carts.

Durability & Upgrades

  • Ceramic Elbows Wear‑resistant elbows extend life on abrasive products and high‑turn areas.
  • Brush Box Powered or passive units scrub chain & discs; tool‑less access and fines tray simplify cleaning.
  • U‑Track Carryover‑eliminating return path keeps fines out of product stream.
  • Retrofit Cable → Chain Replace cable conveyor internals with Chain‑Vey chain/discs and upgraded drive/turnarounds.

FAQ

How do tubular drag chains compare to cable conveyors?

They share sealed‑tube, gentle handling benefits; chain offers greater tensile strength, robustness, and typically longer service life. Existing cable systems can often be retrofitted to chain with new drive/turnarounds and chain/discs.

Do I need filtration at the discharge?

No—systems are sealed. Receiving vessels may still need venting per process needs. CIP tiers manage residue and allergen control between batches.

What tube sizes are available?

Common sizes are 3", 4", 5", 6", and 8" with typical capacities from ~175 to ~2,000 ft³/hr depending on product and layout. We confirm with testing.
