Title: Drum drier - esp for milk with automatic foam quencher
Inventor: SCHRADER ALFONS
IPC: F26B17/28
Filed: 1971-10-26
Abstract: The milk is fed by a pump through >1 pipe opening into the bottom of a feeder trough into which a pick-up roller is partly immersed. This is in contact with an idler transfer roller which in turn is in contact with the heated drying drum whose dia. is >=8 times that of the pick up roller. To prevent bubbles of foam being picked up by the immersed roller, a curved guard plate, whose max. radius of curvature is 30% greater than that of the pick-up roller, is placed just below that roller with provision for adjusting its relative height. Each edge of the trough formed by the guard plate is an overflow weir and the height of liquid level in the main feed trough is also limited by an adjustable height overflow pipe draining into the pipe joining the main reservoir to the feed pump for the supply to the trough. Uniform layer of dried milk is obtd. on heated drum due to avoidance of foam pick-up.

Title: Oil droplets removed by ultra filtration - from spent cleaning, cooling or cutting liqs
Inventor: GAEFGEN KLAUS
IPC: B08B3/08
Filed: 1973-06-14
Abstract: Oil droplets or suspended particles are removed from emulsions or dispersions respectively (used for cleaning purposes) by pref. repeated ultrafiltration, whereby substances having relatively low mol. wt. such as emulsifiers or some detergents, penetrate (together with water) the semipermeable membrane and can be recycled, whilst the emulsion or dispersion becomes enriched in oil droplets or suspended particles (such as soil particles) and, hence, can be more economically processed below the disposal. The process is used for the processing of spent cleaning, cutting or cooling liquids. The quantity of the recycled contaminated liquid is kept constant by adding fresh portions of the spent cleaning liquid in the same amt. as that of the liquid purified by the ultrafiltration and returned. When the contaminated liquid reaches the optional content of the impurities, it is withdrawn to a special tank.
