Fluidised Bed Dryers
Dryers are widely used in pharmaceutical and chemical manufacturing to dry material.
Various dryers are used in the industry, including spray dryers, continuous dryers, tray dryers, fluidised bed dryers. Achieving the desired outlet moisture is crucial, as overdrying can degrade product quality and lead to a loss in gross weight, while underdrying can also affect quality. Hot air flows across the material drying it. Steam is often used to heat air to the required temperature in the air battery and this hot air enables drying.
Some common issues that plants face across dryers
- Hot air temperature variations (+/-5°C from the set value)
- Difficulty reaching desired temperatures
- Water hammering in the air heater battery, causing coil failures
- Condensate evacuation issues
- Higher energy consumption
- Higher batch and startup times
Our Solution:
Forbes Marshall provides a complete solution for dryers. This includes
Precise control of steam pressure, air temperature and flow (- digitally enabled integrated control valve enabling precise pressure reduction and temperature control, with built in steam measurement)
Steam Operated Pump Trap which enables evacuation of condensate under stall (when air temperatures required <100 deg C) eliminating water hammer and the need to open trap bypasses
Steam operated condensate recovery pumps
