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.

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 process for producing decaffeinated green coffee beans, decaffeinated roasted coffee beans or preparations produced therefrom is described, wherein one process step comprises the PEF (pulsed electric field) treatment of (optionally presoaked) green coffee beans. Also described is a decaffeinated green coffee bean, a decaffeinated roasted coffee bean, and a preparation produced therefrom, and also the use of a PEF device for the treatment of (optionally presoaked) green coffee beans. A system for decaffeinating green coffee beans is additionally described.

The invention concerns an apparatus (10) for roasting coffee beans comprising : - a housing (7), - a roasting chamber (1) presenting a bottom opening (11), said chamber extending along a chamber axis, preferably essentially vertical, from said bottom opening, - an air driver configured to drive a flow of air inside the roasting chamber through the bottom opening of said chamber, - an electrical heater (3) configured to heat air driven inside the roasting chamber, wherein : - the air driver (2) and the electrical heater (3) are positioned aside the area vertically below the bottom opening (11) of the roasting chamber.

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

Provided is a method of producing roasted coffee beans, comprising: a first step of adding water to raw material roasted coffee beans, followed by heating of the resultant; and a second step of subjecting the raw material roasted coffee beans after the first step to supercritical carbon dioxide extraction.

An apparatus includes a receptacle configured to receive a container containing a substance for processing. The container includes a readable tag having processing information associated with the substance. The apparatus also includes a processing chamber operably coupled to the receptacle and configured to receive the substance and process the substance. The apparatus further includes a controller operably coupled to the processing chamber and configured to generate one or more processing instructions based on the processing information in the readable tag and further based on additional processing information received from a remote device. The processing is also configured to process the substance based on the one or more processing instructions.

The invention concerns a system for roasting coffee beans comprising: —a roasting apparatus (1), said apparatus producing smoke, and—a smoke treating unit (2) configured to collect and treat smoke produced by the roasting apparatus, wherein: —the roasting apparatus comprises a smoke outlet (11), and—the smoke treating unit comprises: a smoke inlet (21) configured to cooperate with the smoke outlet of the roasting apparatus, a smoke filtering sub-unit (22) comprising at least an active carbon filter (221), a smoke driver (23) configured to circulate smoke through the smoke treating unit from the smoke collecting device to an outlet (25) of the smoke treating unit, wherein the smoke treating unit (2) comprises an air inlet (24) configured to mix the smoke produced by the roasting apparatus (1) with ambient air before the smoke is circulated through the smoke filtering sub-unit (22).

The invention relates to an apparatus (1) for more convenient roasting of coffee. The apparatus (1) in particular facilitates an improved means for discharging or ejecting the so roasted coffee beans from the apparatus (1). The apparatus (1), which may be a home appliance apparatus, comprises a chamber (10) in which coffee beans can be received for roasting. The apparatus (1) further comprises a device for generating a current of air in order to agitate the coffee beans received by the chamber (10). The chamber (10) is delimited by a bottom (11), a top (12), and a sidewall (13) extending from the bottom (11) to the top (12), wherein the sidewall (13) comprises a discharge port (30), which is selectively moveable between a closed position and an open position, such that the current of air generated by the device can drive the coffee beans through the discharge port (30) to be discharged from the chamber (10), when the discharge port (30) is in the open position.

The invention concerns a method to determine the recipe Rym for roasting a quantity m of a type Cy coffee beans in a particular type of roasting apparatus, said recipe Rym providing setpoints (Tym@ti; ti), wherein the method comprises the steps of:—getting access to: ⋅a rule to calculate the roasting recipe adapted to the roasting of a quantity of beans, said quantity being comprised in a list of pre-determined quantities (M, M±Δx), from any pre-existing roasting recipe adapted to the roasting of another quantity of beans in said particular type of roasting apparatus, said another quantity being comprised in the list of pre-determined quantities (M, M±Δx), and to at least one pre-determined original roasting recipe RyMoriginal adapted to the roasting of one original pre-determined quantity Moriginal of the type Cy coffee beans, and—based on the comparison between m, the accessible original pre-determined quantity Moriginal and the accessible pre-determined quantities of the list (M, M±Δx), determining the roasting recipe Rym to be applied on said quantity m of coffee beans.
