Why the emerging strong interest in vertical continuous pans?* [Full subscriber]

Abstract Several overseas cane sugar industries are implementing steam efficient practices in factory processing in order to achieve greater economic value from bagasse, e.g. from cogenerated export power, paper pulp, particle board and (maybe soon) second generation biofuels and chemicals. Many of these factories have installed falling film evaporators as part of the drive to steam efficiency. More recently, strong interest is developing in using vertical continuous vacuum pans (CVPs) with mechanical agitation to undertake evaporative crystallisation on low pressure vapour (e.g. using vapour 3 or vapour 4 bled from the evaporators). The cane sugar industry to now has mostly…
