The MCPI Fine dosing® SPA micro feeders are designed for the precise dosing of powders and granules by weight. Linked to precise scales that control 3 flow rates, the micro-feeder can achieve accuracies to within +/- 1 mg, and short dosing times.

A large range of products :
4 levels of precision – 2 different designs – 2 types of realisation.

► 4 levels of precision for the scales:

► 2 possible configurations for the micro-feeders:
To offer the possibility of integrating these micro-feeders on automated lines, or to obtain simpler systems.

Dosing in a weighed rotating bowl : feeding is performed in “hidden time”, during manipulation of the packing. |
Direct dosing in the packing laid on the balance. |
► 2 types of realisation: “Hygienic” or “industrial”
Problematics in terms of cleanliness and hygiene are not similar to all industries. We propose for industrial process applications, a more economical and less sophisticated design, but still easy to clean.
 |
 |
“Hygienic” design according the definition of EHEDG (European Hygienic Engineering and Design Group):

- Simple design rules
- Easy access to all machine surfaces for cleaning, disinfection and inspection
- Eliminating hidden areas where deposits and biofilm can accumulate
- All surfaces in contact with the material are “FDA” conform .
|
“Industrial” design

- Identical levels of performance to hygienic dispensers.
- Ease of cleaning
- Surfaces are not always polished, depend on process requirements.
- Supports in painted steel
- Economical solutions, with a good value for money

Technical advantages
You will appreciate:
- The Accuracy and stability
- The short dosing time,
- The compactness,
- The reliability,
- The flexibility,
- The safe design for the operators
- and construction based on hygienic standards…
- The intuitive and user friendly operation of the weighing controllers,

MCPI Fine dosing® micro feeders are probably the first on the market to reach such levels of excellence, the main reasons are:
- A feeding system with high dynamic of operation
- A high ratio between coarse and fine feedings. This is essential to perform both fast dosing processing and high precision.
- A reduced and stable overshoot.

MCPI Fine dosing® exclusivities:
►MCPI weighing controllers for an easier operation and a better processing control 
► MCPI Fine dosing®: an exclusive and patented technology, for the highest level of performance .
