Fluidised bed dryer and auto coater machine facing issues of:
- Process temperature fluctuation of ? 5-7 O C
- Higher start-up time – more than twice the desired level
- Higher batch time
- Opening of actuated steam trap bypass valve through a pre-programmed function in PLC, leading to steam loss
- Higher steam pressure (4 bar g) to overcome condensate evacuation issues, leading to water hammer and hunting of control valve
