ABSTRACT

Cooling of beverages is of large interest. Here a theoretical idea of how microwave ovens can be used for cooling beverages is presented. The proposed theoretical idea based on heat transfer features a microwave safe (isoprene rubber) torus shaped rubber ring (MWSR) holding a liquid (L) at room temperature. Fullerenol dissolved in acetone (L) inside MWSR (L) will absorb energy directly from the microwave radiation and thereby increase its temperature. The liquid to be cooled (B) will also absorb energy from the microwave radiation, but the net effect is the cooling of B as the heat transfer is faster in L than in B due to L’s lower boiling point and heat of vaporization. The cooling fan of the microwave oven facilitates the heat transfer mechanism. The beverage B is theoretically cooled from room temperature (20 °C) to around 4 °C in around 58 seconds. Based on heat absorption of fullerenol—which could be transformed from liquid phase to vapour phase—a beverage liquid (300 g water) in a glass put inside the microwave oven could be cooled (reversely heated) by the heat generated by the microwave oven. The user of the proposed method would be able cool 300 ml of beverage to less than 4 °C in just a minute using consumer microwave ovens.
