Challenges and Solutions

Every materials has it challenges, and we have the right solutions to counter them.
Our Coffee Whisper Loaders let you transfer green coffee beans from a bag, super sack or box to a coffee roaster.


Portability requirements

Product movement can be dangerous and tedious. We offer portable feed bin hoppers that allow you to move your products safely and efficiently.


Fragile Products

Our products use speed control as well as a boxed inlet system that helps deduce impact and prevent a breakdown of the materials.


Limited Floor Space

Not every factory has the same amount of space. Our systems are built to work in compact layouts with specially placed side access filters for convenience.


Dust control

Our systems are equipped with primary and secondary filtration systems, and built with high efficiency PTFE filter media that ensure a dust-free environment.

Customize your machinery

  • Custom material inlets. Sanitary inlets,
    boxed inlets and Ferrule/tri-clamp fittings.
  • Under 8 Cubic foot volume limit as safe
    design in view of NFPA Explosion guidelines.
  • Explosion proof motors for Class I/II classified areas.
  • Various voltage configurations:
    120v, 220v, 24V, 460v.
  • Batching Scale hopper to hold/dispense desired amount of material by weight or volume, by loss in weight or gain in Weight.
  • Custom design specific to applications.
  • Batch, continuous, or flood fed systems.
