Varioflow chain conveyor technology supplied by Bosch Rexroth has been installed at United Biscuits’ Harlesden plant to improve the productivity of its digestive production line.

The biscuit manufacturer wanted to upgrade its digestive production line as its current technology was causing the digestives to crumble. For this reason, the company approached West Sussex-based Ingenia Solutions, a specialist in the design, manufacture and installation of custom-built engineering products.

Ingenia Solutions was tasked with replacing the current biscuit transfer system and replacing it with a new system that was faster and incorporated a metal detector station, biscuit transfer arrangement and two off-biscuit transfer units that direct product into the existing case-packing machine.

The company’s solution centred around Varioflow technology — a modular chain conveyor system that can be easily adapted to specific tasks and production layouts. The system includes a six-lane bespoke conveyor arrangement with a bend at the exit of the Varioflow conveyors.

Key benefits of product application

  • The bespoke Bosch Rexroth technology has enabled United Biscuits to increase production to around 60 packs per minute, to improve quality and to eliminate unreliability issues.
  • The Varioflow technology interfaces seamlessly with the existing plant, with bespoke conveyors carrying the product through the metal detectors feeding through the metal detection unit, which ensures that no foreign metallic materials can be introduced into the product along with reject chutes if anything metallic is detected.
  • According to Steve Smith, managing director of Ingenia Solutions, the high-quality Varioflow system is capable of longer chain pulls with fewer motors than any other supplier’s equipment.
  • Smith said that the Bosch Rexroth technology provided a significant saving in both investment costs and running costs for the end user; he added that the Varioflow system is particularly suitable for any industry looking for a delicate handling solution.
