Quick & accurate

Our FCD safely doses rarely used ingredients that can spoil if they remain in the silo for too long. It uses unique exchangeable containers with dosing slides, giving efficient and contamination-free dosing of even small quantities of materials. Ingredients from up to 24 containers can be combined automatically.

Combining high throughput with outstanding accuracy, the ALFRA FCD features our unique dosing slide, which ensures that dosing and weighing no long is a factory bottleneck. Uniquely, it eliminates labor-intensive and error-prone hand dosing – and the alternative of a separate machine for small amounts – by handling from 50 gram right up to 100 kg in a single machine.

Design features like an in-built dust extractor help ensure a clean workplace with minimum or even zero cross contamination. Cleaning, inspection and maintenance are all simple, and running costs are low.

Technical specs


Dosing range 50 g to 100 kg
Dosing accuracy 2 g
Weighing accuracy 1 g
Dosing positions 6 to 40 silo positions


Key advantages


  • High throughput for micro and small components like dry powders, granulates and pellets
  • Virtually reduces cross contamination and residues
  • Low maintenance and running costs, > 20-year operational life


With two weighing scales in one hopper (Weigher-in-Weigher) we make full use of our pioneering dosing slide concept. Dosing large quantities directly into the large weigher – with smaller quantities first going into the small weigher – means high throughput combined with excellent accuracy. Now, the appropriate weigher is selected automatically, reducing the number of silos you need.

ALFRA dose&weigh software

The embedded ALFRA dose&weigh software uses historical data to start the coarse dosing and then adjusts the fine product flow profile dynamically, achieving up to 20% more throughput – even for materials with varying flow characteristics. The improved accuracy saves raw materials, while batch times are shorter and more predictable. Now, materials dosing is no longer a process bottleneck!
