Spirotech Screw conveyor

• Transporting bulk ingredients like flour, sugar, or grains within a food processing facility.
• Moving semi-solid products such as dough or pastes.
• Feeding processing machinery with a controlled flow of material.
• Transferring waste products or by-products in a sanitary manner.

Typical capacity

For a screw conveyor of this class, throughput can typically range from 5 to 30 cubic metres per hour, depending on the product density, screw pitch, and motor speed.

Power supply

Units of this type commonly require a 400V, 3-phase electrical supply, consistent with industrial equipment in the UK.

Construction material

Given its application in food processing, this equipment is typically constructed from food-grade stainless steel (e.g., 304 or 316) for hygiene and corrosion resistance.

Typical screw diameter range

Screw conveyors for food applications commonly feature diameters between 150mm and 400mm, influencing material flow rate.

Common length range

Lengths for this class of conveyor typically vary from 2 to 6 metres, though custom lengths are also common.

Maintenance requirements

Regular cleaning, inspection of bearings and seals, and lubrication of moving parts are typically required to ensure operational longevity and hygiene.

• What types of products are suitable for a screw conveyor?

  Screw conveyors are highly effective for handling a wide range of free-flowing to semi-fluid bulk materials, including powders, granules, flakes, and some pastes. The specific product characteristics will influence optimal screw design.

• Can this conveyor handle abrasive materials?

• Is this unit suitable for outdoor use?

• How difficult is it to clean a screw conveyor?

• What safety features should I look for?

• Can the conveying angle be adjusted?

Buyers typically value conveyor systems for their reliability and longevity when well-maintained. Key considerations when purchasing used units include belt condition, motor functionality, frame integrity, and available spare parts. Industry sentiment emphasises the importance of verifying operational history and cleanliness standards, particularly for food handling applications. Common strengths include robust construction, relatively straightforward maintenance requirements, and cost savings versus new equipment. Reputable manufacturers' models tend to hold their value well and integrate readily into existing production lines.
