This function will help to achieve uniform flow of liquid or gas through the filter cake, while agitater to eliminate liquid and gas channelling that reduces the efficiency of displacement washing and gas blow through. There are certain applications where the desired product to be discharged is not a dry solid.

Agitated Nutsche filters can be fabricated in materials nutscbe Hastelloy C, C, stainless steelmild steeland mild steel with rubber lining as per service requirements. A number of small scale trial units are available for rental, for trials either at your site or in the De Dietrich Process Systems trial lab.

Unlike vacuum drying, it does not require agitation. We are here to help! ANFD’s are available in variants compatible with barrier isolation systems at the discharge. Subscribe today and receive weekly or monthly notifications when new blog posts are published: The filter medium, usually a filter cloth, is fitted on the filter plate which is replaceable type. Mutsche features and advantages:. Alternately sintered plate material or wedge wire Screens can also be provided instead of filter cloth.

We offer Pilot Plant facilities for on-site tests so our clients can gain experience with the advanced features of GMM Pfaudler’s equipment while gathering reliable scale-up and process data.

Pharmaceutical Filter – Pharmaceutical Dryer, Pharmaceutical Mixer, Pharmaceutical Blender

Additionally, these can be combined with automatic packing systems further downline. Contained powder milling, packaging, filtration and drying in a space saving configuration.

Anticlockwise rotation For stirring near filter nutschd to keep it clear of sedimentation and automated discharging. The agitator performs a number of operations through movement in axes both parallel and perpendicular to the shaft. The Agitated Nutsche filter is a Nutsche type filter designed to separate solids from liquids under controlled conditions. If necessary, after first filtration, wash liquor can be sprayed fikter filter bed and cake can be reslurried by manipulation of agitator movement.

Year of Establishment Vaccume is applied for fast drying. Our team of qualified, dynamic and young engineers have extensive industry experience, to manage the entire business including quality standards maintained in our engineering products. Vacuum or pressure filtration possible Inert gas atmosphere can be maintained Minimal contamination of the cake Very high solvent recovery Considerable saving in manpower Solvents are in closed systems, so no toxic vapors are let off in ffilter atmosphere Personal safety is maintained and heat transfer surfaces can be provided nutsvhe maintain filtration temperature.

Mother liquor is sucked through the filter bed and collected in the receiver, which is below the level of lower compartment of the filter, and slowly cake formation begins on the filter media. Drying can be enhanced by purging a hot gas through cake. As the blades descend into the cake mass, the discharge dreyr is opened and a controlled discharge of the cake is achieved. Heated Filter Plate – The fully welded design provides heat energy directly into the cake from the underside, allowing for heat transfer through all of the filter contact surfaces, for jutsche efficient drying.

This is executed by the addition of fresh wash liquid that is mixed with the solids. Full recoveryof the product heel.

Agitated Nutsche Filter and Filter-Dryer

The stirrer blades are lowered to agitate the slurry to obtain good cake washing. In agotated a special design of interchangeable arrangement between filter cloth and multilayered sintered plate can be provided in the same equipment.

Cake Discharging Valve is circular-plug type,welded on the shell just above the filter plate,When closed,it takes exact shape of the vessel. Posted by Jennifer Mayo. It is also available for Sterile applications.

At the closing stage of the filtration process described above, the stirrer blades are lowered on the cake surface. Stay in the know! This design is good for vacuum as well as high pressure applications. Sterile filter-dryers For products requiring sterile manufacturing conditions, filter-dryer can be specifically designed to include stem-in-place SIP capabilities, and eliminate all internal dead spaces. The media should be determined based on the characteristics of the slurry including particle size drer shape, cake porosity, and compressibility which are all factors that, when taken into account with the filter media selected, will determine filtration rate.

This arrangement can assist untsche quick changing of filter cloth and product change. ON FILTER BED Mother liquor is sucked through the filter bed and collected in the receiver, which is below the level of lower compartment of the filter, and slowly cake formation begins on the filter media.

Additionally, the equipment is fitted with a stirrer mechanism which efficiently agitates the slurry during cake washing, smoothens and squeezes the cake during filtration and assists in the automatic discharge of the cake.
