Conveyors (Drag, Pneumatic, Screw)

Specialized conveying equipment used to transport ingredients and finished products (not packages) through a food processing operation, including cable conveyors for small and fragile ingredients. Other examples include tubular drag/disc, aeromechanical, bucket, auger or screw and pneumatic vacuum tubes.

Category Explained

Processing conveyors, or conveyance systems, play a critical role in the efficient movement of ingredients and finished goods within the food processing industry. These systems are designed to handle a variety of materials, from small and fragile items to bulk products, ensuring they are transported safely and effectively through different stages of production. Key types include cable conveyors, which are ideal for delicate ingredients; tubular drag and disc conveyors for versatile material handling; aeromechanical conveyors for high-speed transport; bucket conveyors for vertical lifting; auger or screw conveyors for controlled feeding; and pneumatic vacuum tubes for rapid, dust-free conveying. Each type is tailored to specific material characteristics and processing requirements, facilitating seamless production workflows.

Typical products and applications include:

  • Powders such as flour, sugar, or starches: Moved using screw or pneumatic conveyors for precise and enclosed transfer
  • Spices and seasonings: Handled gently with cable conveyors to preserve quality and prevent breakage
  • Grains, cereals, or seeds: Transported efficiently using tubular drag conveyors between cleaning and blending stages
  • Coffee beans or cocoa nibs: Moved through aeromechanical systems for fast, damage-free transport
  • Dry pet food or snack pellets: Lifted vertically via bucket conveyors for packaging or mixing

Additional Considerations:

  • Minimizes product damage: Systems are designed to match the delicacy or density of the materials being conveyed
  • Supports dust-free environments: Pneumatic and enclosed conveyors help reduce airborne particles and contamination
  • Customizable for facility layouts: Many systems can navigate vertical lifts, tight turns, or long distances
  • Easy to clean and maintain: Available in sanitary designs that support quick disassembly and clean-in-place (CIP) options
  • Helps maintain production speed: Ensures ingredients flow smoothly through processing steps without delays or backups
