Question

6.0 (m) 1.0 (m) 10.0 (m) 1.0 (m) Cooling Drying Forming Wrapper Speed, S (m/s) d (mm) Roller radius r = 0.1 (m) Figure 5: Conveyor layout (not to scale)

The speed S of the conveyor belt is to be determined based on the drying time t (20 min) for each bar and the travel distance of 10 m through the dryer. Ignore that the bar is partly in the drying zone at each end.
The production rate R is to be determined based on the distance d (Bar length 150 mm + 30mm gap between rows) from bar to bar, the number of bars per row N (9 bars) and the speed of the conveyor S.

a) relationship between the speed of the conveyor S, drying time t and drying distance (10 m)

b) relationship between the production rate R, the speed of the conveyor S, number of bars per row N and row to row distance d
