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.

Process steps

1 Filling and homogenisation 5 Emptying2 Pre-coating or pre-filtration 6 Slurry discharge of the filter cake

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
