Embodiment Construction

[0154] figure 1 The torrefaction device 10 is schematically shown during a torrefaction operation. The device comprises a roasting device 1 configured to roast coffee beans 8 . The roasting device comprises a roasting chamber 12 capable of introducing and heating coffee beans. A heater 11 is provided to heat the coffee beans. As mentioned above, any type of baking chamber and heating can be implemented. Preferably, however, the heater is an electric heater. During roasting, coffee beans 8 produce smoke 6 . The flue gas 6 is collected by the flue gas collection device 2 . In the embodiment shown, the collecting means 2 is a simple hood positioned above the fume outlet 13 of the torrefaction chamber in order to capture the fumes. The shroud is positioned so as to maintain a gap 22 from the outlet 13 and to provide a connection to the ambient atmosphere. Other types of fume collection devices may be used; for example, Figure 4 A collecting device 2 is shown comprising a...

Abstract

The invention concerns a method for roasting coffee beans with a roasting apparatus (10) said roasting apparatus being positioned in a room and said roasting apparatus comprising : - a roasting device (1), and - a smoke treating unit (3) configured to treat the smoke produced in the roasting device (1) and to prevent the dispense of air contaminants in the room.

Description

technical field [0001] The present invention relates to equipment for roasting coffee beans in a safe environment. Background technique [0002] Roasting coffee beans is a well known process. The main steps include heating the beans to the desired roast level, then cooling or quenching the heated beans to stop the roast. During heating, fumes are emitted. This smoke contains safe and desirable components all together, especially the common roasted coffee aroma, but also undesired less safe components such as pyridine, 2-furylmethanol, caffeine furfural, formaldehyde , acetaldehyde, CO, CO 2 , NO 2 and particulate matter (PM2.5, PM10),... [0003] When roasting is performed in a manufacturing facility that produces large quantities of roasted coffee beans, all conditions for capturing unsafe components are usually available and there is no interest in capturing aromas. [0004] With small home roasting equipment, being able to smell aromas during roasting operations can...
