Centrifugal sprayer null for spray drying device

摘要

PURPOSE: To make the required power for a centrifugal spray small and achieve the energy saving. ;CONSTITUTION: A secondary spray disk 19 with a number of secondary spray holes 19c, 19c... on its peripheral wall is journaled in a high temperature atmosphere jetting from a hot air jet device and rotated at a proper speed with a secondary drive motor 28. A primary spray means consisting of spray nozzles 17 or a primary spray disk for generating primary fog of a raw liquid to be dried toward the secondary spray holes 19c is constituted on the inner diameter side of the secondary spray disk 19. While the secondary spray disk 19 is rotated, the raw liquid to be dried is fed to the primary spray means to dry secondary fog of the raw liquid to be dried sprayed out of the secondary spray holes 19c of the secondary spray means.;COPYRIGHT: (C)1996,JPO
