| | | Features: • Optimum heat exchange dueto an even airflow through the coffee at high speeds of air anda high volume flow. • Separatequenchingsection. • Low energy consumption due to a closed circuit forthe roastinggas. • Simple,easy-to-maintaindesign. | | |
| | | ing system causes a fast cooling down ofthe coffee. Thesmall quantity of exhaust air is discharged via the recirculating air system ofthe roasting section. The air cooler directlyfollowingthe quench section consistsofa conveyingchannelwith an adjustable unbalance drive and is operated on the fluidized bed principle. The coffee flows across the perforated floor, whilethe cooling air is fed as a countercur-rent. The speed ofair is adjusted in such a waythat the entire bed of roasted coffee is homogeneously fluidized. The retention time in the air cooler can be regulated by adjustingthe drive speed. Measuring, Control and Regulating System (MCR) The roasting plant is controlled by a PC that visualizes the process data. Screen displays, such as process parameters, control circuits, monitoring parameters, and various trend curves, facilitate the operation ofthe plant. A PLC controls and monitors the plant. Any malfunction is registered in a protocol. Theflow rate ofthe roasting gas is controlled by a damper. The roasting gas temperature is measured behind the drum roaster and kept constant by a controller. The speeds ofthe drives ofthefeeding screw, roasting drum, quench unit, and air cooler are controlled via frequency converters and are individually adjustable, or controlled via a special computer program, with onlythe roastingtime being specified. The additon ofwater is determined bythe residencetime in the swingsieve and this adjusts the quantity ofwater. The quantity is measured and displayed. The flow rate ofthe cooling air is controlled by a damper. | | |
