FIELD: food industry. ^ SUBSTANCE: invention relates to food industry. Method includes multiple-factor treatment of product in one volume. It allows for treating biological items in microenvironment with low-power US and microwave oscillations which do not change product properties. Sterilisation is conducted by means of ultra-violet radiation generated from one source - Gunn-effect diode. Pasteurisation is performed by means of infrared radiation generated from tubular resistance-type heater. Main point of device for butter production from cream is that blades are made of a set of plates manufactured from semi-conducting material, which is able to generate US or microwave oscillations under electrical voltage. The following components are introduced into device: spinning system, tubular resistance-type heater, water-cooled jacket, and UV source. Besides, spinning system consisting of cylinder and disk is installed on rotating shaft located along symmetrical axis of capacity. Tubular resistance-type heater is represented as coil located on internal side of capacity. Water-cooled jacket covers capacity from external side along the whole perimeter. UV source being above spinning system is represented as toroid. Pipeline for treated product supply into capacity runs through toroid hole. ^ EFFECT: development of method for industrial diary butter production at high quality indicators and low power costs. ^ 2 cl, 1 dwg |
