Initial liquid containing fine bubbles is produced by mixing water and air (step S11). Fine bubbles have diameters of less than 1 m. The density of bubbles in the initial liquid is measured (step S13), and when the measured density is less than a target density (step S14), the initial liquid is heated and reduced in pressure so that the liquid is vaporized (step S15). As a volume of the liquid decreases, the density of fine bubbles increases, and high-density fine bubble-containing liquid is easily obtained. Alternatively, by increasing the density of fine bubbles in the initial liquid with using a filter that does not pass all fine bubbles, high-density fine bubble-containing liquid is easily acquired (step S15). When the density of bubbles in the initial liquid is greater than the target density, the initial liquid is diluted (step S16).

A beverage mixing system/method allowing faster mixing/blending of frozen beverages is disclosed. The system/method in various embodiments utilizes inductive coupling to introduce heat into the frozen beverage during the mixing/blending process via a rotating driveshaft and attached mechanical agitator to speed the mixing/blending process. Exemplary embodiments may be configured to magnetically induce heat into the driveshaft and/or mechanical agitator mixing blade to affect this mixing/blending performance improvement. This heating effect may be augmented via the use of high power LED arrays aimed into the frozen slurry to provide additional heat input. The system/method may be applied with particular advantage to the mixing of ice cream type beverages and other viscous beverage products.

The temperatures of fuel oils stored in fuel tanks 12a, 12b, 12c are separately detected by temperature sensors 52a, 52b, 52c, respectively. Based on the detection results, a CPU 49 heats a heat resistant fuel oil among the fuel oils using a heat exchanger 54, such that the temperature of an oil mixture generated by mixing the fuel oils satisfies a predetermined temperature condition. After the fuel oils including the heated heat resistant fuel oil are mixed in a blender 13, the CPU 49 detects the viscosity of the generated oil mixture using a viscometer 33. Thereafter, based on the detection result, the CPU 49 controls the mixture ratio or a heating temperature of the heat resistant fuel oil, such that the viscosity of the oil mixture satisfies a predetermined viscosity condition.
