A fluidized bed coffee roaster controls air flow and / or temperature to maintain a desired time-temperature roast profile. The roaster may also provide a two stage quenching cycle for rapidly cooling roasted coffee beans to ambient temperature. In a first stage of the quenching cycle unheated air is passed through the roasted beans while they are still in the roasting chamber of the fluidized bed roaster. In a second stage of the quenching cycle which is carried out outside of the roasting chamber, in a fluidized bed quenching station, unheated air is flowed through, and fluidizes, the roasted coffee beans cooling them to ambient temperature.

A coffee bean roasting machine of the type having a cyclone separator heating chamber and a coffee bean roasting chamber in a recirculating process stream driven by a recirculation fan is operated to air cool the roasted coffee beans in the roasting chamber, to a temperature beneath which the beans give off smoke, while at the same time incinerating smoke removed from the roasting chamber. A purge gate in ducting between the cyclone separator and the roasting chamber is opened to allow the flow of ambient air into and through the roasting chamber while blocking flow out of the cyclone separator, so that ambient air is directed through the roasting chamber. The smoke and any airborne particulate material from the roasting chamber are carried into the heating chamber and through the incineration tube, where they are incinerated. Preferably the system and process are operated automatically by a computer and programming.

A cyclonic chiller-separator, including a vertically oriented treatment tower defining an interior space and having an exhaust inlet disposed in an upper portion, and a chimney with an exhaust outlet; an exhaust stream conduit in fluid communication with said interior volume of said treatment tower through said exhaust inlet, wherein said exhaust inlet is configured to induce cyclonic fluid motion in an exhaust stream entering said interior volume; a coolant water source; and a plurality of nozzles disposed about interior walls of said treatment tower and in fluid communication with said coolant water source for spraying cooling water into said interior volume above and into an exhaust stream introduced into said interior volume so as to cool, condense, and precipitate volatile organic compounds and organic acids, and to entrain and remove particulates from the exhaust stream.

The present invention relates to a coffee roaster having a housing, a supporting plate located within the housing, a drum chamber located at one side of the supporting plate within the housing, a first support for supporting the drum chamber, and a second support for supporting the drum chamber. The supporting plate may include a heater. The first support may be adjacent to the outer circumferential surface of the drum chamber. The second support may be adjacent to the outer circumferential surface of the drum chamber and be spaced apart from the first support by a predetermined distance. As the drum chamber rotates by receiving a driving force for rotation from the first supporting unit, the drum chamber can be rotated without being obstructed by the heater.

The invention relates to a coffee roasting method and device, a storage medium, and a coffee roaster. The coffee roasting method of the present invention includes the following steps: reading the NFC tag associated with the coffee beans, and obtaining the roasting parameters of the coffee beans stored in the NFC tags, wherein the roasting parameters include a roasting temperature curve; obtaining A roasting start instruction; according to the roasting parameters, the roasting elements are controlled to roast the coffee beans in the roasting chamber. The coffee roasting method of the present invention reads the roasting parameters stored in the electronic tag associated with the coffee beans, and roasts the coffee beans according to the roasting curve in the parameters, which makes the roasting process more convenient and improves the quality of roasted coffee. Bean quality stability.

The invention provides an automatic coffee production line with bin-free continuous material feeding. The automatic coffee production line comprises a material feeding platform, a weighing and proportioning machine, a coffee baking machine, a stone removing machine and a weighing packaging machine, which are connected with one another in sequence, and further comprises vacuum feeding machines and a controller, wherein the controller is in control connection with the vacuum feeding machines; the vacuum feeding machines comprise a vacuum raw material feeding machine and a vacuum cured material feeding machine; the material feeding platform, the weighing and proportioning machine and the coffee baking machine are in control connection through the vacuum raw material feeding machine; the stone removing machine and the weighing packaging machine are in control connection through the vacuum cured material feeding machine. Compared with the prior art, the automatic coffee production line with bin-free continuous material feeding is small in investment, small in occupied land, simple and convenient to mount, flexible to operate, sanitary and clean, saves a lot of manpower, replaces an imported product and has prospect of earning foreign exchange through exports.
