The method includes separating a major proportion of the beet molasses into residual molasses 14 and a sugar fraction 15 which is delivered into a refining process 10. All of the residual molasses 14, pressed pulp 7 and trash 3 from the beet preparation process 1 are mixed to form a pulp mixture which is dried in dryers 30, 31. Exhaust gases 40b, 41b, 42b from separate coal fired boilers 40, 41, 42 are delivered into main supply ducts 45, 56 and a secondary duct 47, the main portion of the exhaust gases being delivered to gas mixing chambers 55, 56 for the dryers. A furnace gas tempering portion of the exhaust gases is drawn from duct 47 by fans 48, 49, 50 so furnaces 51, 52 for the rotary pulp dryer and the tempered gases are mixed with the main exhaust gas portion in the chamber 55, 56 to provide a drying gas supply to the pulp dryer at less than 800 DEG C. <IMAGE> |
