Device for in-cup preparation of a beverage
A beverage production device prepares a beverage from a beverage concentrate contained in a receptacle. The beverage production device includes a support member for supporting the receptacle, a plate member arranged vertically to the support means, the plate member including at least four outlet nozzles for injecting a fluid jet into the receptacle. A liquid supply member is connected to the outlet nozzles, and at least two of the outlet nozzles are designed to direct a fluid jet to an inner side wall of the receptacle and are arranged at different angles with respect the vertical. At least two of the outlet nozzles are designed to direct a fluid jet to the bottom of the receptacle and are arranged at different angles with respect to the vertical.
1. A method for preparation of a beverage from a food substance, the method comprising:
providing a beverage concentrate to a receptacle; and
directing fluid jets to the receptacle comprising directing at least two fluid jets to an inner bottom portion of the receptacle and at least two other fluid jets to an inner side wall portion of the receptacle using outlet nozzles provided at a plate member arranged vertically to the receptacle,
wherein the receptacle and the plate member move vertically in relation to each other during the directing of the fluid jets to the receptacle,
the at least two fluid jets directed to the inner bottom portion of the receptacle and the at least two other fluid jets directed to the inner side wall portion of the receptacle are positioned at different angles with respect to the vertical.
2. The method according to claim 1 , wherein the receptacle and the plate member also move rotationally in relation to each other during the directing of the fluid jets to the receptacle.
3. The method according to claim 2 , wherein a motor performs rotational movement of the receptacle and the plate member in relation to each other during vertical movement of the receptacle and the plate member in relation to each other.
4. The method according to claim 1 , wherein the plate member is moved to approach a rim portion of the receptacle prior to the directing of the fluid jets to the receptacle, and the receptacle is rotated during the directing of the fluid jets to the receptacle.
5. The method according to claim 1 , wherein the receptacle has a frustoconical shape.
6. The method according to claim 1 , wherein the outlet nozzles have angles between −10° and +10° relative to the vertical.
