SEPARATING OR REMOVING CREAM FROM MILK IN CENTRIFUGAL CREAMING
MACHINES. A communication from abroad by the Firm of W. Lefeldt & Loutsch,

This Invention relates to a novel and continuous process & apparatus or means
for effecting the continual separation of cream & milk in centrifugal creaming
machines, whereby a constant flow of new milk is allowed to enter in a continuous
stream, & a constant flow of cream and skim milk to leave such apparatus. The
new milk enters a partially hollow or pierced spindle under a given pressure or
head, & issues by lateral apertures from the said spindle entering a central tube
provided with a flange at the further end, an open space or apertures being left
between a loose bottom, & also the inner circumference of a cylindrical or conical
inside vessel of round or polygonal shape in section, & carrying several radial
wings or partitions for compelling the entering liquid to follow the revolving drum.
By suitable openings the skim milk enters a hollow space or grooves, & thence into
the hollow spindle, the outflow of the skim milk being regulated by proper valvos
or cocks.
The cream leaves the revolving drum which may be either cylindrical, conical, or
polygonal by openings in the cover, thence to enter the cream collector with outlet
spout. Or by another method the new milk enters a vertical spindle by an
opening, thence enters a conical tube and round the edges of the flange of the above
conical tube, a conical or cylindrical made vessel of circular or polygonal section
provided with radial partitions. The skim milk enters by openings in the top, an
open space or grooves or chambers, thence, leaving the vertical revolving drum
conical, or cylindrical, or circular, or polygonal section by suitable openings, &
thence into a collecting ring at the bottom with outlet spout. By turning a
loose bottom provided with radial channels or grooves, the more or less intense
outflow of the skim milk can be regulated. The cream leaves the drum by inner
openings passing above the cover into the upper cream collector with outlet spout.
Or the new milk enters a vertical spindle by openings, thence a conical tube, &

above named inside vessel by openings in the cover, moves towards the centre up
to a lid of the drum cover, enters the collecting ring on the top with outlet spout.
By lowering or raising an adjustable slide cover provided with a proper screw
thread the outlet of the skim milk can be regulated, the cream leaves the drum
through openings & rushes above the adjustable cover into a cream collector
provided with proper outlet spout or tube. The vertical or other centrifugal
separating drums may be driven by pulley or belt, friction or toothed gearing,
& may be cast in one piece, or made of sheet iron rivetted or otherwise fixed to the
bottom.
