Vertical Gravity Fed Roasted Coffee Destoner system separates foreign materials encountered in roasted coffee seeds which are heavier in mass than that of roasted coffee seeds, in particular small rocks and stones, by use of an opposing stream of air which is directed in a vertical tube in an upwards direction at the roasted coffee beans concurrently been introduced to the system via a smaller in diameter branched tubing therefore causing the roasted coffee beans to float and divide from the heavier materials.

摘要

The Vertical Gravity Fed Roasted Coffee Destoner makes use of gravity to 5 introduce potentially contaminated roasted coffee seeds into a ducting style system via 1 a side tube branched from the 2 main ducting into which an opposing 3 air stream is been direct in an upwards direction causing lighter in weight material to become airborne and float upwards and 7 out of the system leaving heavier materials resting inside the system's 4 fine mesh which is positioned below where the tubing branches off. These heavy materials are disposed of by opening the 8 side viewer which is positioned level with the 4 fine mesh. The system can run using an off the shelf electric 6 blower the kind that has a motor speed controller attachment and with at least a capacity to produce above two inches of water gauge pressure. The 6 blower is to be located at the beginning of the system and controlled with a speed controller device. All light weight materials 7 exit the system at the opposite end to the 6 blower once it has journeyed up and out of the top of the tubing and it is then collection in tubs ready for packaging or storage. ©5 - . 6
