Title:
PARTICLE PRODUCTION DEVICE AND METHOD FOR PRODUCING FROZEN PARTICLES
Document Type and Number:
WIPO Patent Application WO/2023/224103
Kind Code:
A1
Abstract:
The present invention provides a particle production device and a method for producing frozen particles which make it possible to quickly produce frozen particles while minimizing clogging of a nozzle due to freezing. The present invention provides a particle production device comprising: a freezing chamber for accommodating frozen particles in which a substance to be treated containing moisture is frozen in particle form; an ultrasonic nozzle that converts the substance to be treated into particle form after or prior to freezing and discharges the result into the freezing chamber; and a pressure reduction device for reducing the pressure in the freezing chamber, wherein the moisture in the frozen particles evaporates as a result of the pressure being reduced, and the frozen particles are cooled and frozen as a result of evaporation of the moisture.
