The invention concerns a method to roast coffee beans in a room (100), said method comprising the steps of wherein, when at least one roasting operation is implemented, —obtaining desired roasting data input of said at least one roasting operation, said desired data input, —getting access to information relative to the room and to the coffee beans roasting apparatus, and —before initiating the at least one roasting operation: determining the concentration of each contaminant generated in the room during said at least one roasting operation, for each contaminant, comparing the determined concentration of said contaminant generated in the room with the concentration of said contaminant authorized according to local health and safety regulations.

A roasting and grinding system (100) for preparing and delivering on demand roast and ground coffee, the system having: one or more raw containers (10, 10′, 10″, etc.) having green coffee beans of the same or of different types; a roasting unit (20) receiving green coffee beans from one or more of the raw containers (10, 10′, 10″, etc.) at the time, the roasting unit (20) adapting automatically the roasting parameters to the type of green coffee beans to roast; a conservation area (30) where the roasted coffee is stored at appropriate atmosphere until it is grinded; a grinding area (40) having one or more grinding units (41, 41′, 41″, etc.) one per type of coffee to be ground, adapting automatically the grinding parameters to the type of coffee or coffee mix to be ground. The invention further relates to a raw container (10, 10′, 10″, etc.) having green coffee beans detachably connectable to a roasting and grinding system (100), and to a method for roasting and grinding coffee blends on demand using such a system.

A fluidized electric coffee roaster includes a housing; a fluidizing chamber having a predetermined volume into which raw coffee beans are introduced, discharged, and roasted; a heating unit communicating with a lower end of the fluidizing chamber; an air supply unit connected to the heating unit and supplying external air inside the housing to the heating unit; a raw coffee bean injecting unit connected to an upper end of the fluidizing chamber and allowing raw coffee beans to be injected into the fluidizing chamber from an outside; and a coffee discharging unit connected to a lower end of the fluidizing chamber and allowing roasted coffee to be discharged, wherein air heated by the heating unit is supplied to the lower end of the fluidizing chamber and is discharged to an upper end of the fluidizing chamber so that the raw coffee beans are circulated from a lower part of the fluidizing chamber to an upper part of the fluidizing chamber and roasted.

The present invention relates to an air-drying plant for air drying cut-up food. The proposed plant consists of a conveyor (10) for cut-up food (1) defining a conveying surface (11), a plurality of blowing conduits (20) with blowing openings (21) channeling a treated airflow at a speed of treatment with a controlled temperature comprised between 4° C. and 60° C. and a controlled humidity; wherein the conveyor includes air treatment segments (12) with conveying surfaces (11) facing and adjacent to said blowing openings (21), said treated airflow being channeled against said conveying surface (11) in an upward or downward direction; and wherein the conveyor (10) also includes idle segments (13) intercalated between said air treatment segments (12), the conveying surface (11) of which is not facing the blowing openings (21), nor is it subjected to an airflow.

Disclosed is a vacuum roaster including a chamber, a door cap formed on one side of the chamber so as to be opened or closed, a vacuum cap formed on an opposite side of the chamber, a basket spaced apart from an inner circumferential surface of the chamber, and including a basket door that is opened or closed for introduction and discharge of an object to be processed, a vacuum adjustment device for adjusting a vacuum state inside the chamber, a drive motor connected to the basket via a shaft for rotating the basket, and a heater provided inside the chamber so as to be spaced apart from the basket.

The invention concerns an apparatus for roasting coffee beans comprising:—a vessel (1) to contain coffee beans,—an electrical heating device (13) to heat coffee beans contained in the vessel,—at least one temperature sensor (23) to measure temperature in the vessel, —a control system (180) operable to control the heating device, wherein the control system is configured to:—apply a roasting recipe dedicated to the roasting of partially pre-roasted beans comprising at least a temperature versus time profile by controlling the electrical heating device based on the measure of the temperature sensor,—detect a decrease of the consumption of electrical power of the heating device in function of time,—stop heating if no decrease of the consumption of electrical power happens after a set reference time ti.—continue or stop the electrical heating device depending on the type of identified beans.

A coffee roasting apparatus (100) is disclosed comprising a compartment (110) for holding coffee beans (10); a roasting element (140) for roasting the coffee beans in said compartment; and a controller (130) for controlling the roasting element, wherein the controller is adapted to control the roasting element as a function of the concentration of volatile organic compounds residing in the compartment. A coffee brewing apparatus including such a coffee roasting apparatus and a coffee roasting method are also disclosed.
