The first and probably the only completely hygienic loss – in – weight feeder !
The MCPI ® Fine dosing weight loss feeders are unique for their original design, totally focused on processing and cleaning efficiencies.

A unique and innovative design
- The simple design: the drive and weighing sensors are protected in a Stainless steel housing.
- The process performances, over the best screw feeders (for accuracy + extraction efficiency of difficult powders), in both batch or continuous process.
- 100% hygienic design.
- Maintenance free feeders ( no wearing parts).
- Safe for users

Hygienic loss in weight feeder with scattering function |
Main advantages:
Feeding accuracy |
Thanks to the exclusive patented principle that offers:
- A short reaction time and a reduced and constant overshoot
- A large difference between coarse and fine flows (over 100 to 1). This point is essential to achieve a short dosing time and a good accuracy (in batch process).
- A short term stability of the output flow (in continuous process).
|
Extraction of difficult materials |
- An effective extraction of the most difficult materials (eg pigments, aromas, TiO2, starch…).
- As a consequence, our feeders don’t need agitators in the storage hopper (advantages: safety, cleaning, maintenances).
|
Flexibility |
- With the same feeder, it is possible to work with abrasive ingredients (sand, glass..) or very cohesive powders.
- A very wide range of ouput flow rates
|
Respect of material |
- The powder extracton is performed without mechanical friction.
- The integrity of delicate ingredients is preserved, no compaction occurs during operation.
|
Hygienic design |
- Design free of retention area, the feeder drains completely. Within a few dozens of seconds, without tools, the parts in contact with the feeder are disassembled.
- The material is only in contact with stainless parts.
- Water resistant, the feeder can be washed with hot water. The inclined surfaces promote drainage).
- All mechanical parts are protected in a housing (no more difficult parts to clean – eg: motor, load cells…)
|
Reduced maintenance |
- The absence of mechanical friction is synonymous with reduced wear.
- An accidental intrusion of a foreign body along with the material has no consequence on the feeder (unlike screw feeders where the same cause produces irreversible damage).
|
Safety for operators |
- The maximum stroke of the mechanical parts is less than 2 mm, thus excluding safety risks.
- No agitator or rotating parts inside the feeder.

MCPI weighing controllers designed for the operation of accurate feeders 
MCPI Fine dosing ® : an exclusive and patented technology, for the highest level of performance 
 |
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 .
