Facts
Infeed is always carried out by a vertical batch feeder to ensure that the sugar batch is fed into the pulling area uniformly: this occurs either in batches by the cooling and tempering table or continuously by the cooling and tempering conveyor.
The sugar mass runs through a pulling system of many counter-acting rotating pulling arm pairs, which each circle around two rigid pulling arms. As it moves through this pulling arm system the sugar mass is ventilated intensively and uniformly. The intensity of the pulling process is affected by the speed of the rotating pulling arms and by the dwell time of the sugar batch. The dwell time is determined by the position of the scrapers and the fed sugar mass amount. Further transportation is carried out by the systematics of the pulling arms and of the scrapers. At the end of the pulling section a pair of scrapers takes the pulled sugar batch out of the machine. A continuous flowing, uniform drawn sugar mass rope is created that, for instance, can be fed over an after-cooler conveyor to the downstream production lines.
