DEVICE FOR PRODUCING DISPERSED SUBSTANCE MIXTURES BY MEANS OF ULTRASOUND AND THE UTILIZATION OF SUCH A DEVICE

摘要

The invention relates to a device for producing dispersed substance mixtures by means of ultrasound, especially a device for producing mini-emulsions, i.e. emulsions having an average droplet diameter of less than 1 mu m. The ultrasonic device comprises a housing (11), a reaction chamber (12) provided in the housing and at least one sonotrode (13) which has a free radiating surface (14) and is operatively connected to the reaction chamber (12). The radiating surface (14) of the sonotrode (13) essentially corresponds to the surface of the reaction chamber (12) or extends when the reaction chamber (12) is a partial section of a flow-through reaction canal (15). The radiating surface extends essentially over the entire width of the canal (15). The depth (12b) of the reaction chamber (12) which is essentially vertical to the radiating surface (14) is smaller than the maximum effective depth of the sonotrode (13).
