Gravimetric micro feeders

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:

Class	Weighing resolution of the scales	Min. quantity (estimation)	Max quantity (estimation)	For batch feeding of dry materials
A	100 mg	> 10 g	~ 20 kg
2A	10 mg	> 250 mg	~ 500 g
3A	1 mg	> 100 mg	~ 100 g
4A	0.1 mg	> 20 mg	~ 10 g

► 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.
