Abstract
Abstract The present invention relates to a method and a device for preparing beverages such as coffee, tea and cocoa in portions in containers such as plastic cups, said containers being first partially filled with a pre-measured amount of flavored powder and thereafter filled up with water. According to the invention water is added under slight overpressure via a water outlet head (3) for partial filling of the container, during which pressure water is added via separate nozzle heads (4) to ensure thorough whipping of the flavored powder in the water.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
160 words
A method for preparing beverages at ambient pressures, comprising (a) adding a premeasured amount of flavored powder to a container; (b) partially filling said container with a first quantity of water introduced into said container through at least one water supply outlet at a first velocity and a first mass rate of flow; and (c) substantially simultaneous with step (b), introducing a second quantity of water at a second velocity, which velocity is higher than said first velocity, and a second mass rate of flow, said second mass rate of flow being lower than said first mass rate of flow, through at least one nozzle to substantially fill said container and effectively mix said powder and water to produce a beverage, wherein the diameter of said outlet is larger than the diameter of said nozzle whereby the velocity of said second quantity of water is sufficient to intensively mix by whipping said water and said flavored powder within said container.
Claim 2
Independent Claim
160 words
A method for preparing beverages at ambient pressures, comprising (a) adding a premeasured amount of flavored powder to a container; (b) partially filling said container with a first quantity of water introduced into said container through at least one water supply outlet at a first velocity and a first mass rate of flow; and (c) substantially simultaneous with step (b), introducing a second quantity of water at a second velocity, which velocity is higher than said first velocity, and a second mass rate of flow, said second mass rate of flow being lower than said first mass rate of flow, through at least one nozzle to substantially fill said container and effectively mix said powder and water to produce a beverage, wherein the diameter of said outlet is larger than the diameter of said nozzle whereby the velocity of said second quantity of water is sufficient to intensively mix by whipping said water and said flavored powder within said container.
Claim 3
Dependent Claim
27 words
The method of claim 1 wherein the first quantity of water is added in such a way that the beverage within said container is caused to circulate.
Claim 4
Dependent Claim
20 words
The method of claim 1 wherein the pressure of the second quantity of water is about 3-4 Kp/cm 2 .
Claim 5
Dependent Claim
18 words
The method of claim 1 wherein said second quantity of water comprises about 5-25% of said prepared beverage.
Claim 6
Dependent Claim
29 words
The method of claim 1 which further includes the step of spraying a third quantity of water over the surface of the liquid to subdue any foam formed thereon.
Claim 7
Dependent Claim
25 words
The method of claim 5 wherein the sprayed third quantity of water is sufficient to dissolve any grains of flavored powder present in the foam.
