Outline

• A high-shear-mixer-granulator-dryer, combining the steps of mixing, granulation and drying in oral solid dosage form production

• Thus, single pot processing (SPP) is the

production of pharmaceutical granules using a wet granulation process in which dry mixing, liquid addition, wet granulation, drying and sizing of the granules is done in one machine.

Drying mechanism

Combination of heating, tilting the bowl, vacuum, microwaves, Transflow

No drying

Flexibility: Single Pot Processing: mixing, granulation and drying in

1 machine - number of material handling steps is decreased

Drying technique : Vacuum-drying, microwaves, Transflow and swinging bowl – improvement of the granule characteristics and a reduction in drying time

Explosion proof design

Containment: Perfect GMP-design, easy to clean, CIP system Dust-free loading

Design features and Benefits (1)

Swinging Bowl: better granulate quality and faster drying User friendly: operator-machine interaction (Video

monitoring) Top driven mixer and chopper: easy cleaning, GMP accepted Process parameters are independent of atmospheric

conditions High yield Reduced use of cleaning liquids Solvent recovery systems Change over in less than 2 hours Compact technology – reduce space requirement

Design features and Benefits (2)

1. Wet granulation - Water based, solvent based2. Vacuum drying3. Effervescent products – to control fusion

reaction 4. Oncology drugs, hormonal products or highly

potent compounds- special care require to avoid exposure of the operators

5. Hot melt granulation6. Pelletizing7. Coating

Application

‘Top Driven’ advantage

Shaft seals are not in direct contact with the product : No risk for cross contamination

Easy to clean and inspect : full accessibility with open bowl

No need for hoist to remove the impeller blade

Liquid addition system

Granulation endpoint determination NIR and FBRM (Focused Beam Reflectance Measurement) : Measurement of moisture content, homogeneity of the mix and particle distribution Visual observation through camera Torque measurement of Impeller and Chopper

Drying mechanism

Vacuum Drying - Principle • The boiling point of liquids is lower at lower pressures• By applying vacuum in the bowl, the boiling point of the granulation

liquid used is significantly decreased.

Characteristics of Vacuum Drying System• Highly efficient vacuum system (roots bower + Vacuum pump)• Energy supply through heated jacket of lid and bowl• Liquid recovery unit ( 1 or 2 condensers)

Schematic Diagram of Technical Area

TRANSFLOTM Drying

Microwave Drying - Advantage • Energy supply independent from

vessel wall; wall temperature can be controlled in order to avoid caking

• No risk of wet lumps (drying inside to outside)

• Significantly reduced drying time• Scale up of drying time is linear

(linear to installed μ-wave power) ; similar drying time small and large batch size

SPP – Control System

SPP – Containment Buck Valve/ Hicoflex technology for loading and discharging Isolated boxes for higher toxic compounds Contained sampling valve Oxygen sensor provided to ensure the level is below the explosion limits Oxygen replaced by Nitrogen gas in a automatic cycle

Buck Valve Hicoflex Valve Oxygen Sensor Isolated Box

Cleaning system (1)

• Through the wall design, small area to clean

• Numerous improvements to avoid gaps and dead space inside the bowl in order to make WIP/CIP easier

• No permanent cabling and piping around the machine
