Solutions for efficient ingredient unloading

Transfer food, ingredients to fillers and mix kettles utilizing the unrivaled Graco SaniForce Unloader systems. Reduce manufacturing costs by improving material evacuation rate, time, and efficiency. Without contaminating, diluting or heating ingredients, the SaniForce Unloader systems achieve up to 99% evacuation rates of high viscosity ingredients such as tomato paste, chocolate, and fruit paste.

Maximum Unloading. Transfer Efficiency

  • Up to 99% evacuation rate
  • Inflatable seal for optimal performance
  • Flange connections for easy cleaning
  • Fits most bins, drums and containers
  • Available with piston pump and air operated double diaphragm pump options
  • Available in CE1935.2004 – check manual for configuration (signs toevoegen)

The drum unloader is fast and easy to operate. Once the drum is placed below the drum unloader, the ram plate and pump are lowered into the drum, just above the product. Then, the seal is inflated to hermetically seal the drum. When the pumping starts, the product is moved out of the drum and the plate with inflatable seal travels down, scraping the product from the sides of the drum. After the drum is emptied, the plate and pump can get lifted out by simply switching a button.

Advantages of the SaniForce Drum Unloader

  • Up to 99% evacuation rate which voids the need (completely or almost completely) for an operator to scrape the wall and dump leftover material into the feeder. This reduces operator time.
  • No more labor intensive work for the operator as the operator doesn’t has to use force in order to get all product out of the container. The operator doesn’t even have to be with the product when it’s working.
  • Overall improved ergonomic work environment. Operators don’t have to use stairs or overstretch to get the product out of the container.
  • Improved usability thanks to the automated control system. By adding a PLC interface, the unloading process can be operated remotely and it allows operators to multi-task easier with a more consisten operation from shift to shift.
  • No need to dump big amounts of materials (200/400 kg) into hopper devices which can result in damaged machinery.
  • Clean and easy operation as product will be guided all the way.


Other technologies the Unloading Systems could replace

The drum and bin unloading systems can replace Lift-and-Dump systems. Lift-and-Dump systems are used to transfer big amounts of materials stored in containers. During the lift-and-dump process containers are lifted to variable heights through open air, than the container is tilted so the product can fall out, which brings several risks for workers and their surroundings.  After every dump you still have to scrape the walls of the container manually which is work and time intensive.

Also there is a bigger chance of injuries on the work floor as operators often have to hang over stairs to reach the remaining product in the container. Likewise overstretching is one of the main injuries when working with a lift and dump system. Another risk is the big amount of product falling from a height which can impact or even damage the hopper system.

Céréco improves the unloading of its fillings

Thanks to the success of their co-extruded organic breakfast cereals, the annual volume of fillings used (principally chocolate) has increased eightfold between 2010 and 2018. The fillings were delivered in 10 to 25 kg buckets then manually emptied into a buffer hopper next to the extruder. The operators could no longer keep up with the higher production rates. That’s why they started to look for an ergonomic and ecologic alternative…
