Abstract:
In Germany the production of equipment for
industrial soap factories looks back at a tradition
of nearly one hundred years. In that period
rich experience has been collected by steady development
of the machinery. Trials for new
modes of processing in addition to improved
manufacturing methods guarantee the highstandard
equipment today. .
For the production of soaps several kinds of
fats are required, mainly beef tallow and coconut
oil, but also palm kernel oil as well as castor
oil, olive oil, peanut oil and pore tallow in
smaller quantities. The liquid fats are boiled
with the aid of steam and saponified with caustic
soda lye. Glycerine is recovered by washing with
brine. For the production of laundry or toilet
soap the neat soap has to be dried and cooled.
The finishing of laundry soap is achieved by extrusion,
imprinting and cutting of the solidified
soap slug, whereas the procedure for the finishing
of toilet soap is more expensive, requiring
the steps of mixing, homogenizing, refining, extrusion,
cutting, pressing and wrapping.
