IBC unloading of wheat, special purpose conveying and packing system for woven wheat filled ‘Heatpacks’ of varying size

Customer requirement: A small high growth company who manufacture a range of wheat filled microwavable ‘heatpack’ products for domestic retail market needed a solution to fill the woven heatpacks using a simple semi-automatic packing system, to increase production and de-skill their current manual packing method.

  • The customer needed to increase their production and de-skill the current packing process.
  • Reduce the reliance on a few skilled workers that could be redeployed to higher value production roles.
  • Remove the need for forklifts to operate within the production area.
  • The system needed to be reliable and to fill a range of heatpacks from 300-600 grams.
  • The system needed to run between 2-6 filled packs per minute.

Gimat solution: The application was quite unique as the customer had been filling the woven heatpacks manually and was unsure as to whether the system would satisfy all of their needs. The customer having no on site engineering staff looked to GIMAT to produce a cost effective simple to operate reliable packing solution.

  • GIMAT supplied a purpose built rigid IBC unloader to transfer the wheat into the conveying system.
  • The GIMAT conveying system consisted to two 55 mm diameter flexible screw conveyors to transfer the wheat to the pneumatically operated discharge head.
  • Each discharge head was individually controlled and foot pedal operated in order that the operator could set the transfer speed and time to fill the heatpacks independently of one another.
  • GIMAT provided a simple control system with all of the controls housed within a single control panel to allow the customer to quickly and easily change the conveying parameters depending on the size of woven pack that was being filled by the operator.

This application was customer driven and GIMAT produced a tailored engineered solution to ensure that the customer demands were met, GIMAT provided the mechanical installation and commissioning of the systems.


Sack Tipping, Conveying & Vertical Mixing of Epsom & Himalayan salt for processing and repacking into plain and fragranced bath salts

Customer requirement: Current management team have experienced a surge in growth for their repacked range of homeopathic plain and fragrance bath salts. To maintain pace with demand the customer installed a new multi-head weighing system and needed a bulk handling solution to deliver both plain and mixed bath salts to the packing machine.

  • The customer needs a reliable conveying system to deliver plain bath salts which were decanted from 25 kgs sacks.
  • To add value to the plain salts Westlab wanted to mix the plain bath salts with a range of fragrances.
  • The control system was needed to integrate with the multi-head weighing system to produce a seamless turn-key operation from sack tipping to conveying to the mixing processes.
  • Any equipment needs to be easy to clean and all contact parts had to be 316L stainless steel.
  • The system needed to be reliable and capable of operating at 16 hours per day.

Gimat solution: The customer was very specific with the requirements as this new system represented a significant investment and was a key aspect to their growth targets. GIMAT provided Westlab with on-site trials to prove the vertical mixing technology would work effectively with the range of fragrances that they would be mixing with the plain salts. The customer provided GIMAT with a footprint of the space available and the engineering team then had to provide a solution to work within the site restrictions.

  • GIMAT supplied a 500-litre sack tip hopper for the operator to manually unload the base into, this hopper would then either transfer directly to the multi-head weighing system or into the vertical GIMAT mixer.
  • Any material that needed to have fragrance added would be fed into a 1000 litre GIMAT vertical mixer, this mixer featured all 316L contact parts and is a vertical version of a ribbon blender, the vertical configuration allows a minimum amount of material to be retained after each mix and assist the customer during the cleaning processes between different fragrances.
  • The control system was designed to work with the multi-head weighing system so that either plain of fragrance material could be conveyed to the inlet hopper on the multi-head weigher.
