(c) The tea industry uses a continuous fermentation unit (CFU) that uses a conveying mechanism that moves slowly loaded with tea ready for fermentation. The fermentation process takes about 2 hours after which the tea proceeds to a drier. You are required to design a drive system for the CFU. This drive system is expected to receive power from a motor through a belt drive system that drives a gearbox that eventually drives the CFU. (1) Sketch schematic representation of this drive system Indicate, with explanations, some of the decisions to be made and factors to be considered in this design. Please note that actual computations are not necessary. (15 Marks) etholong. one
