Abstract
A beverage brewing apparatus and method using microwave energy is disclosed. The apparatus comprises a pressurizable water reservoir and a filter chamber disposed below the reservoir. The reservoir is provided with pressure overflow means which, in operation, prevents water in the reservoir from overflowing into the filter chamber until vapor pressure is built up in the reservoir due to the influx of microwave energy so as to force the heated water to overflow into the filter chamber to mix with an infusible material, e.g. ground coffee to make a beverage.
Claims10
A method of making a beverage from an infusible material in a microwave oven, which employs an apparatus having a microwave transparent pressurizable liquid reservoir disposed above a microwave transparent filter chamber adapted to hold a quantity of the infusible material, the reservoir and the filter chamber adapted to be placed over a beverage receptacle, the liquid reservoir being in fluid communication with the filter chamber through a pressure overflow means, the method comprising:
- pouring a liquid into the liquid reservoir to a level not exceeding the overflow level of the overflow means,
- placing a supply of an infusible material in the filter chamber,
- pouring a liquid into the beverage receptacle,
- closing said reservoir, positioning it over said filter chamber and placing the reservoir and the chamber over the receptacle,
- heating said liquid in said reservoir and in said receptacle with microwave energy to raise the liquid vapor pressure in the reservoir sufficiently to force said liquid from the reservoir through the pressure overflow means into the filter chamber to make a beverage, and to raise vapors from the liquid in the receptacle to contact the infusible material in the filter chamber, and
- collecting the beverage in said receptacle.
A beverage brewing apparatus for use in a microwave oven, adapted to be placed over a beverage receptacle having an open upper end, cmprising:
- a microwave transparent filter chamber having a filter positioned in a bottom part thereof, the filter adapted for holding a quantity of an infusible material and for the dispensing of a brewed beverage therefrom into the receptacle, and
- a pressurizable microwave transparent reservoir adapted to hold a quantity of a liquid up to a predetermined level, the reservoir positioned generally above said filter chamber, and
- a pressure overflow means through which the reservoir is in fluid communication with said chamber and which is adapted to hold the liquid within the reservoir until pressure in the reservoir rises sufficiently to force the liquid at least partly through the overflow means into the filter chamber.
