Fluid Bed Dryer Material Loss Reduction

Problems at the site

Fluid bed processors, also referred to as fluidized bed processors or fluid bed dryers, are widely used in pharmaceutical manufacturing for granulation and drying processes.

However, failures or deterioration of bag filters can lead to the unintended discharge of fine powders, resulting in raw material loss, reduced product yield, and potential quality deviations.

In addition, undetected filter damage may cause cross-contamination and increase the risk of non-compliance with GMP requirements.

Solved by the Dust Monitor

The triboelectric dust monitor provides continuous 24-hour monitoring of particulate leakage to verify normal bag filter performance.

Implementing the dust monitoring system to detect filter breaches offers a promising solution for reducing raw material waste and improving process efficiency in the fluidized bed drying and granulation process.

Provides 24H continuous measurement which is highly correlated with the absolute measurement (isokinetic sampling method) at a reasonable cost.

No complicated commissioning required.

It is done by selecting a measurement range with screwdriver only.

Compact type, Remote sensor type, Correlation compensation function, High temperature resistant, Ex-proof (Ex ib IIB T4), Corrosion resistant, etc.

Achieved by the technology

It detects even minute leaks (0.1mg/m3 or over) when filter begins to break, and it is possible to prevent the valuable raw materials leak.

It replaces a human and continuously monitors 24 hours a day.

It is possible to reduce maintenance work such as cleaning work for dust leakage, etc. because it tells you before dust leaks.

Inside of dust collector is divided into multiple rows and backwashed in row order.

Leakage during backwashing appears as a trend for each row, so there is no waste by replacing only the filters in rows with a large amount of leakage.
