Deposit-free transport of wax contg. liquid - by injecting coolant to produce turbulence

摘要

A hot mixture of a liquid with fatty substances (wax), derived from flushing out the wax from plaster casts in the manufacture of artificial dentures is transported free from deposits by cooling the mixture and at the same time producing an intense turbulence. This causes the wax to become precipitated in the shape of fine droplets which run off the walls without forming any deposit. This prevents any clogging of the pumps or the pipe system even when no emulsifiers have been added to the liquid.
