Centrifuge-Dryer System

For Pharmaceutical Industry

1) CENTRIFUGE

The centrifuge is a horizontal scraper centrifuge in pharmaceutical execution designed according to GMP standards and has the following characteristics:

The machine has the same basic design for both the wall execution and the conventional free mounted execution. In the wall execution the process end of the centrifuge is isolated by a special square flange which is the front of the mechanical end.

In the free mounted execution the mechanical end is sealed by a gas tight cover. Cooling of the drive motors is provided. The centrifuge case can be opened to facililtate cloth changing and to verify CIP- cleaning or inspection.

This centrifuge – dryer provides complete isolation of pharmaceutical products from the reaction step to the final packing.

The centrifuge is equipped with the following GMP accessories :

• CIP-cleaning with validation programming facilities
• Residual heel removal system with nozzles behind the basket (blow back)
• Probe type cake thickness detector
• Imbalance and bearing temperature

2) DRYER

The Drying system consists of a single drying vessel and a wall mounted power and utilities station. The Drying vessel is designed as a vertical conical vacuum rated vessel with pressure jacket for heating . The cover is provided with the vacuum flange, the product filling connection and the drive coupling with the agitator. The power and utilities station contains the frequency controlled drive motor, the vacuum pump with condenser and the customer furnished heating. By using different vessels for each product group cross contamination is virtually eliminated.

Step-1
The Drying vessel is mounted on a lifting and swiveling column and connected to the centrifuge by means of a special double valve system. The active part of the valve is mounted on the centrifuge and the passive part on the vessel.

This allows the drying vessel to be removed from the centrifuge totally closed and isolated.

Step-2
After the product is discharged into the vessel is lifted to the frequency controlled power station. The vacuum and the heat utilities are then connected and the drying process can be started according to drying characteristics of the product by controlling both the agitator speed characteristics of the product by controlling both the agitator speed and jacket heat.

Step-3
After Drying, a stainless steel barrel is connected to the vessel with the same type of double valve used between the centrifuge and vessel, so that the product can be discharged in a totally isolated manner.

The cleaning of the vessel is done filling with washing solution and agitating at high speed. The vessel can be inspected by opening the cover.
