One Pot Processor: VAC 150 - 2000 Mixer Granulators

The One Pot Processor by DIOSNA VAC Series is designed for mixing, granulating and vacuum drying of pharmaceutical products in a closed system.

The flexible building block principle of VAC 150 to VAC 2000 offers for very gentle processing, short drying times and simple operation. Our VAC equipment is designed down to the very last detail to fulfill any practical requirement. Special designs and components for individual applications can be provided on request.

One Pot Processor VAC 150 - 2000 Features:

• Efficient mixing, granulating and vaccum drying in a closed system
• Through-the-wall-installation with auto-lift lid
• Large gasstripping bottom nozzles for fine gas distribution
• DIOSNA Toollift for easy cleaning and simple inspection
• Automated cleaning.

Principle of the VAC 150 - 2000 One Pot Processor:

• Insulated cylindrical bowl with two heating zones
• Mixing tool with wall scraper
• Auto-lift lid (heated to avoid condensation)
• Gas-stripping bottom nozzles
• Vertical chopper
• Industrial PC control
• Process observation through inspection glass or integrated video camera
• Various cleaning options (CIP/WIP)
• Highly accessible, user-friendly machine frame

The mixing bowl is cylindrical with two heating zones and isolation. The hinged lid is actuated automatically and it is heated to avoid condensation. The bowl bottom is equipped with gasstripping nozzles of Sinter metal which care for very fine and gentle distribution of the gas. The nozzles are suitable for WIP and can be lifted pneumatically for inspection. One blade of the mixing tool is equipped with a wall scraper which removes deposits without touching the wall. This way sensitive or strongly adhesive products can be dried in a very short time. Opposite to the usual mixer/granulators the chopper of the VAC series is installed from above (otherwise it would collide with the scraper).

As well as the optimal design of the bowl and the mixing and chopper tools, the vacuum system and the heating/cooling units play a decisive roll for product quality and process times. The vacuum unit is a heavy duty two stage unit. The majority of the granulating liquid vaporized in the VAC, is condensed and recovered. The heating/cooling system works with two separate closed circuits, each one with it's own control and regulation. The water is heated electrically or – on request – using steam.
