1. Feed
Material
Dosing
To be done by a belt weigher.
This means the mass flow into the
coating system is controlled very
accurately. This leads to stable
condition for the coating process
& consistent product quality.
To be done volumetric by a feed screw.
This means the dosing is not very
accurate & will fluctuate depending on
moisture, feed size (bulk density is a
function of particle size) etc. This
means the exact mass flow into the
coating system can not be determined
exactly. Therefore the coating degree
cannot be controlled accurately.
2. Scope
of supply
- Supply the level sensors for the
feed silo
- Supply a ferro magnetic cascade
- Has a material flow controller
that stops the stearic acid flow
when no product is flowing
Not supply the level sensors for the
feed silo
- Not supply a magnetic cascade to
prevent ferro magnetic material to be
fed into the coating system
- No material flow controller

3. Melting unit Has a mixer to promote good and
faster melting of stearic acid in
melting tank
No mixer in the melting unit. This
can lead to not molten particles in
the stearic acid tank which can
lead to oversize particles in the
final product.
4. Tip speed of
de-
agglomeration
device
101 m/s. Since Alpine has 2 rotating
disc that are rotating in opposite
direction the differential speed
between the outer part of the discs
is ~200 m/s. This leads to very
good mixing performance.

Fully automatic. Semi automatic. Especially the
feeding cannot be set to a certain
mass flow. It has to be adjusted
by trial and error.
