Magnetic separator for
chocolate flakes
We received a request from a producer
of chocolate garnish for cakes, biscuits
and yoghurt. The garnish is in the form
of chips and granules that could possibly
contain tiny pieces of metal less than
<1 mm in diameter. This is a common
problem in the production of chocolate.
We were asked if we could filter the
pieces containing metal out of the
product flow, without loss of product.
HIGH GRADIENT MAGNETIC
SEPARATOR
To achieve this, we developed a high
gradient separator with a strong
magnetic conveyor roller, specifically for
the food industry. With this system we
achieve exceptionally high separation
efficiency, not just for iron particles,
but also for weakly magnetic stainless
steel particles, such as AISI 304 and
AISI 316. The high gradient separator is
more effective than a free-fall magnetic

separator, because with the latter you
have to slow down the metal particle
before you can capture it. In addition
to chocolate, the magnetic separator
is also suitable for other dry, granular
products, such as herbs and spices.
HOW IT WORKS
The process itself is simple. A vibrating
chute feeds the chocolate flakes and
pellets onto the conveyor belt and
distributes the products in a single layer
over the belt. The conveyor belt turns
around the magnetic roller that captures
and carries away the metal-containing
product. The clean product falls directly
into the packaging machine.
CLEANING
Hygiene is of the utmost importance,
especially in the food industry. This
is something we considered carefully
while designing the HG separator. A
quick release system makes removal
and replacement of the conveyor
belt quick and easy. The special open
construction and covers that easily
swing out of the way make the system
easy to clean.
