The MAVASPHERE ® Spherical Dryer, introduced just two years ago, is a better option to conventional Conical Screw Dryers and Pan Dryers. These come with
special features like:
• Highly efficient and uniform drying
• Minimal product hold-up and efficient CIP
• High working capacity and good turndown ratio
• Optimal mixing of product
• Complete product discharge
MAVASPHERE®
Main area of application of the MAVASPHERE® spherical dryer as a multi purpose unit are the drying of pharmaceuticals (API) and
finechemicals under cGMP-compliant conditions. Excellent drying performance over a wide range of filling degree (turn down ratio).
High availability due to simple machine design and very good access for inspection.
Design features
• Complete coverage of vessel with jacket
• Minimal gap between vessel wall and agitator (spherical half machined)
• Discharge valve (spherical disc valve) at lowest point
• Gas lubricated double mechanical seal installed outside of the product zone
• Flexible installation possibilities (installation in floor, steel or free standing)
• Effective cleaning
The patented Mavag double acting impeller is designed to reduce wear & tear of
the bearings. Other features include:
• No contamination, no emission and no sealing problems
• No maintenance required, trouble free operation for longer periods of time
• Multiple stage impellers are available for cell culture and microbial fermentation
• Easy to clean and sterilise (CIP/SIP)
MAGNETIC DRIVE AGITATORS
Cleanability
Process wetted components are designed in a way to eliminate deposits during the
process phase and that for cleaning cycles besides flooding other CIP concepts can
be used:
• Oscillating movement of the agitator head by patented counter acting blades
• Largest gap between containment shell and agitator head for best possible
cleanability
• Inclined surfaces and accessibility of all wetted areas
• Dead zone free construction in combination with slots and holes.
• Adjustment of the operating parameters and of the cleaning cycles during
selection of process parameters

Funda ® Filtration is the separation of solid particles from aliquid with the help of porous layers that allow the liquid to pass through but retainthe solid matter.Main features include:
• Totally enclosed vessel without any risk for people / environment.
• Rotation of the filter assembly discharges the cake in dry / slurry form.
• Self-cleaning system
• Suitable for both batch and continuous processes
FUNDA ® FILTER
The FUNDA®-Filter can be operated completely automatically.
The automation of the FUNDA®-Filter is done in coordination with the customers. The filter isconsidered as a system component. It is an integrated part of the process controller and belongsto the network that connects other process equipment, such as pre-coat vessel, pumps, valvesand instrumentation.

3 Filtration 7 Heating, drying
4 Heel volume filtration 8 Dry cake discharge
Pressure nutsches are available with centrally mounted and height adjustableagitator:
• To distribute, smooth, reslurry, suspend and discharge of the filter cake
• For the separation of suspensions with relatively high solid content
• For the solid separation with intensive cake washing
Typical filter parameters are:
• Filter area 0,17 – 15 m²
• Vessel volume 100 – 15’000 liters
• Cake height 50 – 500 mm
