Title: Instant milk powder production
IPC: A23C1/04
Filed: 1970-04-08
Abstract: Thickened milk is thrown out of a first chamber into a second where it is spun into gaps between parallel rotating perforated discs. The product is thus separated into a light fatty low liquid fraction which is sprayed out into the drying chamber, and a second heavier non-fat and higher liquid content fraction which is also sprayed into the chamber in such a way that the two sprays collide, agglomerate and drop to the base of the chamber for removal as instant milk product. The separation into two fractions makes for a higher quality product, with assured agglomeration and grade.

Title: Fluxless soldering - by low-frequency vibration of heated copper electrode
Inventor: MATUSCHEK MAX
IPC: B23K3/00
Filed: 1972-07-26
