초록

A method and apparatus to brew coffee with cold water and automatically dispense it into a container after a specified brew time. Water and a packet of coffee grounds are introduced to a brew chamber to produce a coffee extract after a specified time and then delivered to a removable receiving container. The packet is compressed to release the maximum amount of extract from the packet. Extract can be diluted with additional water into the removable receiving container to create the beverage. The receiving container is filled and sealed for freshness.

1. A system for cold brewing coffee comprising: a container of coffee grounds;a source for providing cold water;a main frame including a brew chamber for receiving cold water from said source and holding said container of coffee grounds to allow mixing of said water with said coffee grounds, said brew chamber having an outlet to allow brewed coffee to flow therefrom;a squeezing mechanism within said brew chamber for holding said container of coffee grounds and squeezing same; and,an actuator coupled with said squeezing mechanism for moving said mechanism to squeeze said container of coffee grounds therein, wherein:said container has a permeable wall allowing water in said brew chamber to wet coffee grounds within said container,said squeezing mechanism has a pair of mutually opposed walls allowing flow of water to said container,said walls are movable by said actuator to squeeze said container and create coffee extract within said brew chamber. 2. The system of claim 1 wherein: said source includes a water receptacle coupled to said brew chamber; and, further comprising:a water valve to control flow of said water from said receptacle to said brew chamber. 3. The system of claim 1 wherein: said mutually opposed walls form an upwardly opening v-shape with adjacent bottom ends and spaced apart top ends, said brew chamber has a guide slidably receiving and supporting at least one of said top ends as said actuator moves at least one of said walls toward the other squeezing said container located between said walls. 4. The system of claim 1 and further comprising: a timer operably connected to said outlet of said chamber to control the amount of time said cold water mixes with said coffee grounds in said chamber prior to said coffee flowing out of said outlet. 5. The system of claim 4, wherein said source includes a water receptacle coupled to said brew chamber;and further comprising: a water valve to control flow of said water from said receptacle to said brew chamber; anda dispensing valve connected to said outlet and to said timer to control flow of brewed coffee from said brew chamber and the amount of time the cold water and coffee grounds are together in said brew chamber. 6. The system of claim 1 wherein said source includes a water line extending from said source and into said container of coffee grounds. 7. The system of claim 1 and further comprising a timer. 8. A system for cold brewing coffee comprising: a container of coffee grounds;a source for providing cold water;a main frame including a brew chamber for receiving said cold water from said source and holding said container of coffee grounds allow mixing of said water with said coffee grounds, said brew chamber having an outlet to allow brewed coffee to flow therefrom;a squeezing mechanism within said brew chamber for holding said container of coffee grounds and squeezing same; and,an actuator coupled with said squeezing mechanism for moving said mechanism to squeeze said container of coffee grounds therein, wherein:said squeezing mechanism has a pair of mutually opposed perforated walls allowing flow of liquid from said container,said walls are movable by said actuator to squeeze said container and create coffee extract within said brew chamber. 9. The system of claim 8 wherein: said mutually opposed walls form an upwardly opening v-shape with adjacent bottom ends and spaced apart top ends, said brew chamber has a guide slidably receiving and supporting at least one of said top ends as said actuator moves at least one of said walls toward the other squeezing said container located between said walls. 10. The system of claim 8 wherein: said source includes a water receptacle coupled to said brew chamber; and, further comprising:a water valve to control flow of said water from said receptacle to said brew chamber. 11. The system of claim 10 and further comprising: a timer; and,a dispensing valve connected to said outlet and to said timer to control flow of brewed coffee from said brew chamber and the amount of time the cold water and coffee grounds are together in said brew chamber. 12. The system of claim 8 and further comprising a timer. 13. An apparatus for making cold brewed coffee from coffee grounds and cold water comprising: a receptacle for holding cold water;a container for holding coffee grounds, said container fluidly in relation to said receptacle for receiving water therefrom;a housing having a brew chamber and an outlet;a timer connected to said outlet and said brew chamber to control the period of time said cold water and said coffee grounds are mixed together in said brew chamber; and,a compressing mechanism within said brew chamber for receiving and holding said container and operable to compress said container holding coffee grounds to produce coffee within said brew chamber; wherein said container of coffee grounds has a liquid permeable wall with said water line extending into said container. 14. The apparatus of claim 13 wherein: said receptacle is mounted on said housing and includes an outlet with a pump connected thereto, said receptacle includes a water line connected to said pump and to said container directing water from said receptacle into said container. 15. The apparatus of claim 13 wherein: said mechanism includes a movable wall and a device for moving said movable wall against said container to squeeze same. 16. The apparatus of claim 13 and further comprising: water line means connecting said receptacle of cold water to said container and directing said cold water into said container. 17. The apparatus of claim 13 wherein said container has a liquid permeable wall and further comprising: water line means connecting said receptacle of cold water to said brew chamber for said cold water to flow from said receptacle into said brew chamber with said water flowing through said liquid permeable wall wetting said grounds within said container. 18. The apparatus of claim 13 wherein said brew chamber includes a first valve for controlling water from said receptacle into said container of coffee grounds and a second valve for controlling flow of coffee out of said brew chamber.
