Equipment and systems we manufacture and supply

Auto debagging systems

We design and fit custom auto debagging solutions that cover a broad range of bags, are simple to operate, and are highly reliable. Our auto debagging systems are cost-effective additions to processing plants, as they:

  • Greatly reduce plant labor and overheads
  • Improve production rates
  • Minimize downtime

Our heavy duty debagger efficiently separates the bag from the material with minimal product carry-over. The system can debag from 100 to 600 bags per hour. The debagging rate depends on the product and the bag construction.

Our auto debagging systems generally work by feeding bags into an in-feed chute. The bags then slide along the chute into a series of rotating blades. These blades slit the bags prior to them entering a rotating trommel screen, which is a perforated tube that tumbles the slit bag to separate the product from the bag. The product drops through the perforations into a feed hopper while the waste bag moves along the tube towards a compactor for disposal.

Blending and mixing systems

Mixing in the powder handling industry generally involves forcefully combining granules and powders with large quantities of liquids to form a homogeneous material. The mixture then becomes a liquid, or semi-solids such as a cream, dough or paste. Blending involves combining granules and powders in a gentle manner, making the material inseparable but not necessarily homogeneous. It can involve combining solids with solids, or solids with small amounts of liquid. Examples of blends are making cake mixes or colouring expanded cereals.

Blending and mixing systems are tailored to specific process requirements and may be either a continuous or batch process. Most powder handling projects utilize the batch approach as this:

  • Ensures better control over quality, batch size and make-up
  • Minimizes risk of contamination of completed and stored batches
  • Simple and accurate minors addition

Pneu Powders Systems deliver blending and mixing solutions such as high speed, low or high shear mixers, in line blending, energy-efficient mixing and much more.
