Abstract
Abstract A method of preparing liquid mixtures of predetermined composition, particularly beverages, which comprises the steps of dosing components of the liquid mixture on the basis of weight and evacuating a mixing container to a pressure of less than 0.5 atm. abs. Then individual components of the liquid mixture are drawn into the mixing container by means of valves controlled in succession in dosing devices from storage containers which are under higher pressure than the mixing container.

Claim 1
Independent Claim
170 words
A method of preparing a beverage consisting predominantly of water and including a plurality of other components, said method comprising the steps of: a. metering quantities of each of said other components by weight into respective storage receptacles and pressuring each of said storage receptacles with CO 2 ; b. evacuating a premixing container and a mixing container simultaneously to a pressure of at most 0.5 atm. abs.; c. successively communicating at least two of said storage receptacles with said premixing container to induce the respective components to pass by suction from said storage receptacles into said premixing container; d. connecting said premixing container to said mixing container to induce by suction the contents of said premixing container to empty into said mixing container; e. thereafter drawing water by the suction in said mixing container into the latter and at least in part through said premixing container for mixture with said components in said mixing container; and f. discharging the mixture of said components with water from said mixing container.
