ULTRASONIC ATOMIZER DEVICE FOR ASEPTIC PROCESS

摘要

The present invention provides an ultrasonic spraying device which is capable of maintaining temperature of an ultrasonic vibration generation unit in which the ultrasonic vibration generation unit is exposed to high-temperature environment by cooling the atmospheric temperature around the ultrasonic vibration generation unit. The ultrasonic spraying device includes: an ultrasonic vibration generation unit for generating ultrasonic wave and atomizing a sprayed material; a spraying path in which the sprayed material moves along the central axis which penetrates through the center of the ultrasonic vibration generation unit; a nozzle unit for receiving the sprayed material from one side of the spray path and including a nozzle tip for spraying the spayed material; a housing which surrounds the ultrasonic vibration generation unit and having a plurality of heat exchange rooms inside wherein the plurality of heat exchange rooms are located around the ultrasonic vibration generation unit inside the housing and include a vortex room for guiding the flow of the vortex, and a heat insulation room having a partition wall which is in contact with the vortex room and an internal heat insulation space.
