Abstract
In the method for preparing metered amounts of a drink in situ such as coffee, from soluble powder, a concentrate of a drink is produced by dissolving determined quantities of soluble powder with water. Then part or all of the concentrate is diluted in hot or cold water in order to produce a metered amount of a drink. The device for the implementation of the method includes an enclosure using a defined large volume of soluble powder and a relatively small defined quantity of liquid such as water, for dissolving the powder in the liquid so as to produce a concentrate in situ, and device for diluting part or all of the concentrate in a liquid in order to rapidly produce individual metered amounts of a drink.
Claims13
A method of automatically preparing at least one metered amount of a drink from a soluble powder in situ in a drink preparation device comprising the steps of:
- completely dissolving under atmospheric pressure a defined quantity of said powder forming a volume having an upper surface contained in an enclosed receptacle in said device by dispersing under atmospheric pressure a defined quantity of water, in a gentle and homogeneous manner, over said upper surface of said volume of soluble powder into said enclosed receptacle with a flow rate sufficient for a volume of water to accumulate at the surface of the powder to produce a concentrate of a drink contained in said enclosed receptacle while venting said enclosed receptacle;
- storing said concentrate of a drink in said enclosed receptacle;
- and, subsequently, taking off part or all of said concentrate from said enclosed receptacle and diluting the taken off concentrate in water to produce at least one metered amount of said drink.
A method of automatically preparing metered amounts or pluralities of metered amounts of a drink, from a soluble powder in situ in a drink preparation device, comprising the steps of:
- placing in a container part of said device, a bag containing a defined quantity of said powder forming in said bag a volume having an upper surface, dispersing under atmospheric pressure a defined quantity of water, in a gentle and homogeneous manner, over the totality of said upper surface of said volume of soluble powder in said bag with a flow rate sufficient for a volume of water to accumulate at said surface of the powder, to completely dissolve said powder and to form a concentrate of drink in said bag;
- and diluting part or all of said concentrate in water to produce a metered amount or a plurality of metered amounts of said drink while venting said bag.
