Aspects of the present disclosure generally relate to systems and methods for processing biomaterials in the absence of atmospheric oxygen and products resulting from such processes. Such processing techniques may dramatically increase the shelf-life expectancies of roasted and milled biomaterial products when the roasted and milled biomaterial products are not exposed to oxygen during processing.

A fluid bed coffee roasting system is disclosed and configured for roasting batches of coffee beans of varying sizes. In at least one embodiment, the system provides a roasting unit configured for roasting a volume of coffee beans, a chaff collection unit positioned and configured for drawing off and capturing any loose chaff released by the coffee beans within the roasting unit, and a cooling unit positioned and configured for receiving and cooling the coffee beans after they are removed from the roasting unit.

Described is a system for roasting, grinding, brewing and dispensing coffee comprising: an infuser head in fluid communication with a source of hot water and comprising bedding means for distributing coffee grounds such that they are disposed substantially evenly on an inner surface of a slidable wall of a coffee cartridge thereby forming an extraction bed within an extraction chamber; and infuser means comprising one or more outlets for the hot water, the infuser head being adapted to deliver hot water to the extraction bed within the extraction chamber, whereby coffee is extracted to yield a coffee brew.

Described is a system for roasting, grinding, brewing and dispensing coffee comprising a coffee cartridge containing: (i) unground and (ii) unroasted or part-roasted coffee beans, said cartridge having walls defining a cartridge chamber in which the beans are confined, wherein part or all of at least one wall of the cartridge is openable, and the openable wall of the cartridge is opposed to a slidable wall thereof, said slidable wall comprising: inner and outer surfaces, the inner surface being in contact with the beans; a peripheral sealing portion on the inner surface; and a central portion bounded by the peripheral sealing portion and comprising a screen for retaining the beans within the cartridge chamber while permitting a flow of coffee brew therethrough.

A method for roasting coffee beans comprising the steps of a) heating the coffee beans until the temperature of the coffee beans is at least 180 C.; b) injecting a stream of oxygen-containing gas into the flow of hot air after the burner; and c) maintaining the injection of the stream of oxygen-containing gas until the end of the roasting process to mitigate the concentration of carbon monoxide in the roasting chamber, and wherein the coffee beans are roasted in a rotating fluidized bed roaster.

A method and system for preparing coffee includes roasting green coffee beans, thereby resulting in roasted coffee beans; grinding the roasted coffee beans, thereby resulting ground coffee; and degassing carbon dioxide from the ground coffee.

Apparatus for roasting coffee beans, the apparatus comprising: a casing that defines an internal void, a baffle for dividing said internal void into first and second zones that are in fluid communication with one another; a heater for heating air to temperatures suitable for roasting coffee beans, said heater being located in said second zone; a control system for controlling the apparatus; said control system being located in said first zone; and a fan operable to draw ambient air into said first zone and drive said air from said first zone past said baffle into said second zone for heating by said heater, the arrangement being such that in use said first zone is cooler than said second zone.
