Services
Carolina Pelleting offers contract manufacturing services that
include blending/mixing, pelleting, extrusion, spheronization,
drying, classification and packaging. Also offered is a range of
microencapsulation techniques.
Mixing/Blending/Granulation
Several mixing techniques are available including plow mixing as
well as mixer granulation.
- High Speed Choppers
- Wet or Dry Mixing
- Melt and Conventional Wet Granulation
- Laboratory V-Blender

Pelleting
Pelleting is performed by a pellet mill type operation where
rollers press material through a die plate. The die plates are
selected in order to give the right physical properties such
as:
- Hardness
- Bulk Density
- Size
- Fixed ratios

|
Low-Pressure Extrusion
Low-pressure extrusion takes a moist mass and wipes it through a
screen to form small noodles.
- Radial, Axial and Basket Type
- Typical sizes from 0.5 mm up to 2 mm.
- Laboratory scale testing with production scale processing in
conjuntion with partners.

|
Spheronization
Spheronization entails taking an extrudate, cutting/breaking it
into short lengths then rounding the particle into a spherical
shape. Spheronization is typically performed when the material is
moist so that it can plastically deform much like a lump of clay.
Spheronization can also be used to condition granules so that fines
in the final product are reduced.
- Laboratory Scale Testing
- Production Scale Processing
- Batch or Continuous Operation

Cooling/Drying
A vibrating fluid bed dryer is used to gently dry or cool the
particles. After pelleting operations where frictional heat of the
process fuses the material together, the pellets need to be
returned to near room temperature prior to packaging. Here, ambient
air is drawn into filters and blown through the material as it is
vibrated across a chamber. For products that require drying, steam
coils are used to heat the incoming air.
All exhaust air is filtered to remove dust particles.
- Gentle Drying or Cooling
- Processing Temperatures up to 275*F as a standard but can be
increased to 350*F by special request.
- Plug flow design
- Two stage fluidization
|
Classification and Packaging
All products are fed through a magnetic separator and classified
prior to packaging.
- Wide sizes of screens for classification
- Packaging options include bulk bags, Gaylords, drums and valve
bags.
