Abstract
A device and a method are for sterilization of milk from livestock such as cows, sheep or goats. The milk, prior to an irradiation with UV-C light through a light translucent barrier, is homogenized since the milk is exposed to ultrasound. The milk simultaneously to or after the homogenization is exposed to an electrical field, such as a field with changing polarity, where polarity change and field strength are chosen such that the milk in the electrical field is heated due to the milk's resistance.
Claims27
A process equipment for sterilizing milk, wherein the process equipment comprises a tempering tub with a light source for irradiation of the milk with UV-light with a predetermined ultraviolet wavelength, the process equipment additionally comprising a separate treatment tub, and wherein the separate treatment tub comprises at least one ultrasound transducer designed to send ultrasound through the milk and at least one unit for ohmic heating by sending current through the milk.
