Title: Powder formation from fusible materials - by spraying into cooler with temp. control of product
Inventor: GRUBER FRANZ
IPC: B01J2/04
Filed: 1975-09-04
Abstract: Process for pulverisation of materials which fuse easily and cannot be pulverised at ambient temps., involves atomising the liq. through a jet and freezing the droplets in a cool air stream. The quantity of liquid introduced into the cool air stream is controlled by the temp. of the final powder product. There is a temp. probe in the product run off to measure its temp. This sends a signal to a metering pump which regulates the feed of liquid material to suit the product temp. The metering pump system consists of a pulse unit which then controls the motor on the metering pump. Used for making powders from e.g. paraffin waxes. The system described is suitable for making friable powders from such materials. Method avoids control involving the opening of a by-pass on the refrigeration plant compressor and thus improves the energy efficiency of the unit.
