ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
A hand-operated, small kitchen appliance to prepare coffee, tea, soy, rice, milk and/or egg beverages, froths and desserts. The kitchen appliance homogenizes saturated and unsaturated fat into skim milk, milk, cream, soy, rice, egg and similar foodstuff. The kitchen appliance is used to microwave-roast green coffee beans, soy beans, rice grains and similar beans and grains to provide microwave-roasted snacks, beverages, froths and desserts. Both alcoholic and nonalcoholic beverages and desserts, with and without foam toppings, are described frozen, chilled or heated. Semi-permanent, nylon-mesh filters replace disposable paper filters.
2. Discussion of the Prior Art
Hand operated French Press coffee makers are well known. Hand operated milk frothing apparatus are well known, for example the apparatus taught in U.S. Pat. Nos. 5,580,169 and 5,780,087.
My U.S. Pat. No. 5,635,233, “Methods for Preparing a Coffee, Tea or Milk Beverage,” teaches separating the plunger-strainer of the French Press coffee maker into a plunger member and a contiguous filter member.
My U.S. Pat. No. 5,800,852, “A Coffee/Tea, Table Blender and Microwave Oven Apparatus and Methods for Its Use,” teaches to combine the utility of a conventional blender and a microwave oven. U.S. Pat. No. 5,800,852, teaches to blend and brew, in the jar of a table blender, coffee, tea or herbal tea immersed in a liquid. Then the brewing coffee, tea or herbal tea, in the blender jar, is removed from its motor base. The blender jar containing the still brewing beverage is placed into a microwave oven, exposed to microwave energy and heated. The blender jar, containing the microwave heated, still-brewing beverage, is returned to its motor base and the blender motor is energized to finish brewing the beverage. The finished brew is filtered out of the blender jar through a reusable filter that covers the blender jar. The instant invention is useful to prepare a cappuccino-type froth for use on top of a beverage prepared in my table-blender/microwave-oven coffee, tea and herbal tea apparatus.
My copending U.S. Pat. No. 5,925,394 for “Methods for Denaturing and Whipping into a Foam Certain Denaturable Proteins Found in Milk Products and Egg Products” teaches how to produce long-lasting milk and egg froths and how to increase the fat content of the resulting product. This copending application concerns electric mixers. This copending application teaches that, if desired, alcohol can be used.
My copending U.S. patent application Ser. No. 08/715,396, filed Sep. 13, 1996, for “Methods of Freezing and Defrosting Certain Foodstuffs in a Microwave Oven,” teaches how to freeze and dispense frozen froths and desserts.
Prior-art, hand-operated, milk-frothing apparatus, when operated rapidly, repeatedly up and down, permit liquid fat and coffee ground to by-pass and/or block the frother member. Prior art electric table blender, the hand operated beaters and electric mixers can permit a by-pass of liquid fat when blending and mixing the liquid-fat, milk and egg mixtures, taught herein.
It is well known that commercial equipment exists to homogenize fat in milk. Soy milk and rice milk are well known commodities.
SUMMARY OF THE INVENTION
A kitchen appliance is taught that combines a French Press coffee maker, a milk frothing device and a device that can homogenize fat into milk, egg, soy, rice and other liquid products. The kitchen appliance's plunger is designed to filter coffee and tea, to froth milk, cream and egg products and to homogenize saturated and unsaturated fat into skim milk, milk, cream, egg, soy, rice and other liquid products. The kitchen appliance can consist of multiple containers. The kitchen appliance can employ multiple plungers, for example, a dedicated plunger agitator, per se, a dedicated plunger strainer, per se, a dedicated homogenizer plunger, per se, and a dedicated frothing plunger, per se, or one or more plunger-strainer-homogenizer-frothers. In one embodiment, the plunger-strainer is separated into a plunger member and a contiguous filter member as taught in U.S. Pat. No. 5,635,233. Here, the plunger member and contiguous filter can homogenize fat into beverages while they retain their prior utility. More than one nylonmesh Lycra® filter cover and filter covers of different gauge, dimension and elasticity can be part of the kitchen appliance. Both alcoholic and non-alcoholic beverages and desserts can be prepared frozen, chilled or heated, and with and without a foam topping. The beverages, froths and desserts taught are best prepared in a microwave oven but may be prepared on a conventional gas or electric burner. In addition to plain and enriched-with-oil beverages (e.g. coffee, soy milk and rice milk), froths and desserts and the like, filled milk, microwave-roasted rice, microwave-roasted soy and the like beverages, froths and desserts are taught. “Microwaveroasting” of green coffee beans, soy beans and rice is taught. The “microwave roasted coffee beans” are ground and brewed into an “enriched microwave roasted coffee.”
It is an object of this invention to provide a kitchen appliance to homogenize saturated (e.g. butter and the like) and unsaturated fat (e.g. vegetable oil and the like) into skim milk, milk, cream, egg, soy, rice and other liquid beverages to increase their fat content.
It is an object of this invention to homogenize butter fat into skim milk, milk, and cream to produce conventional beverages, froths and desserts.
It is an object of this invention to homogenize unsaturated fat into skim milk, milk, cream, egg, soy, rice and other liquid protein beverages to produce filled beverages, froths and desserts.
It is an object of this invention to brew coffee, generate a milk froth, and prepare a cappuccino-type beverage in the same serving container.
It is an object of this invention to employ a semi-permanent nylon-mesh Lycra® filter cover as a replacement for conventional disposable coffee and tea paper filters.
It is an object of this invention to employ a semi-permanent nylon-mesh Lycra® filter cover as a replacement for the stainless steel screen component of a French Press strainer plunger.
It is an object of this invention to provide apparatus to microwave-roast dried soybeans, dried rice and the like to create microwave-roasted snack foods, beverages, froths and desserts.
It is a further object of this invention to provide a kitchen appliance that utilizes and complements the teachings of my U.S. Pat. No. 5,635,233, my U.S. Pat. No. 5,800,852 and my copending U.S. patent application Ser. No. 08/746,809, filed Nov. 18, 1996. For example, the instant invention can be used, as taught in my copending U.S. patent application Ser. No. 08/746,809, filed Nov. 18, 1996, to prepare a milk or egg froth to add on top of a hot beverage. For example, the instant invention can be used to microwave-roast green coffee beans, dried soybeans, dried rice and the like prior to grinding them into grounds and brewing them in my “Table Blender and Microwave Oven Apparatus.”
