Systems for Fatty and Oily Products
Taste, smell, color and fineness of
foodstuff- and luxury food products, especially from
cocoa beans, depend, besides the quality of the raw
material, mainly on the professional preparation, the
coordination of the machines and systems as well as on
the experience of the production personnel.
The size reduction- and sifting machines
used in these preparation steps hereby influence the
product quality in a decisive manner.
For pulverization of cocoa nibs,
depending on the fat content, the required
fineness and the type of
the desired end product, different fine
grinding systems are used. A slightly de-oiled, dark
cocoa powder for drink production with a remaining fat
content of at least
20% is produced by means of
a wide grinding chamber housing or with
For a heavily de-oiled cocoa powder with
less than 20%, however with a minimum of 10% remaining
fat content, which is used i.e. for cooking purposes
such as cakes, puddings etc.,
Turbo Mills, type REF
The systems used are as varied as
Mills, Universal Mills with turbo
rotors, Hammer Mills and Sifter Mills.
Cool air and the right temperature in a
downstream cooling area are essential factors for the
dark color and color fastness of the cocoa powder as
well as a prerequisite for downstream air classifying.
The preparation of fatty, oily and sticky products is
best left to the experts. Increasing demands in product
quality and in the economical use of the system require
constant improvement and development of process
Fine Grinding of Fatty and
In the feedstuff industry,
parts of animals, which are not suitable for human
consumption, are further processed into animal flour.
Animal flour is enriched with valuable proteins and is
used as additives for animal feedings or as fertilizer.
high fat content leads to screen blockages in common
mills. PALLMANN solves this problem with the Original
A significant characteristic
of the Contra-Selector Mill™ is the screen basket
counter-rotating to the impeller. Due to the high
revolution of the screen basket, the screen remains
clear. Due to the additional scrapers at the exterior of
the rotating screen basket, material sticking to the
interior of the housing is minimized.
The advantage resulting
thereof is a continuous method of operation and thereby
minimized operating costs.
