Abstract: A device for grinding coffee beans one shot at a time. The device may consist of an inlet funnel attached to a main body, wherein the beans are gravity fed to a set of burrs that grind the coffee into a grounds chamber, where they are then expunged into a grounds receptacle. The grounds receptacle may be adjusted in height via arms attached to the grinder depending on the workflow of the user and the type of receptacle being used. The grounds chamber is a clamshell design easily removable by the user for cleaning and held in place with magnets and alignment pins. As the grinder grinds coffee, wipers on the mounts for the burr create a positive pressure air flow to expunge the ground beans in addition to physically manipulating them out of the exit chute. This allows for grinding and expulsion of all of the input coffee without retention, a common problem in the industry when grinders are used for single shot grinding.

Abstract: A device for steaming and/or foaming milk primarily for, but not limited to, coffee beverages. The device attaches via machined threads to a standard coffee machine steam wand, but nonstandard sizes can be accommodated via a thread adapter. The device consists of two machined stainless pieces each with crescent shaped apertures that, when rotated relative to each other, allow for the increase or decrease in effective hole size to adjust the volume and pressure of steam being expunged. This adjustability allows for the user to decrease the aperture when foaming a small amount of milk (e.g. for a macchiato), or to increase the aperture for foaming more milk (e.g. for a latte).

Abstract: A device for precise dispensation of whole coffee beans. The device may consist of a coffee bean hopper attached to an incremental dispensation device such as a toothed gear rotated by a stepper motor, whereby the rotation of the gear precisely dispenses whole coffee beans into a receptacle mounted upon a load cell or other weighing device. As the beans are dispensed into the receptacle, a PCB or other electronic component controls a feedback loop from the weighing device to the motor such that the dispensed amount is within +/?one coffee bean in weight. The desired weight may be input via buttons attached to the PCB with a readout that allows 0.1 g accuracy, or roughly the weight of one coffee bean.
