Conveyor for mixt. of flour and fat - uses cooled compressed air for fluidisation of mixture without affecting fat

摘要

A conveyor and dispenser system for flour which is mixed with fat, has its performance improved by injecting compressed air into the mixture. This fluidizes the flour so that it flows in the conveyor pipes without forming blockages. Since the air from the compressor has an increased temperature, up to 50 deg.C, the fat in the mixture tends to melt. Thus by transferring the compressed air through a heat exchanger where its temperature is reduced by about 20 deg.C the flour can be fluidized without affecting the fat it contains.
