Machine concept basic…
 Large service door enables easy cleaning of the
mixing chamber.
 Self-discharging mixing trough geometry.
 Gap-free and surface-treated mixing chamber
prevents product cross-contamination.
 All machine parts in contact with the product are
of stainless steel.
 Continuous seal of the outlet flap guarantees
absolute leak tightness.
 Solid stainless steel construction, withstanding
the forces generated due to mixing cycle
 Robust, completely welded mixing tools
Machine concept “ Chopper”…
 Mixer with plow shares and
choppers for specialty mixes with
solids dissolution.
 Up to four choppers enable an
intensive crushing and mixing of
individual components. Fat blocks
of up to 25 kg are easily process
able.
Performance…
 Consistent and reproducible mixes thanks
to optimal geometry of trough and mixing
tools.
 Qualitatively Excellent Homogeneity (CV) of
no greater than 5 % at a mixing ratio of
1:100’000.
 Guaranteed mixing quality – even at filling
levels as low as 20 % of maximum rated
capacity.
