The pilot design of agitated nutsche filter dryer (ANFD) is a multifunctional equipment created for multipurpose producing operations. Promas Engineer’s ANFD is equipped with several functions adhering to the latest patterns and technological innovation this kind of as, equal capability filtrate collection receiver underneath vacuum, solvent, recovery, compact design and style, heating preparations, chilling arrangements, lifting & decreasing. The filters are meant to meet up with severe cGMP and Food and drug administration specs and demanding specifications for filters used in the production of pharmaceutical factors. All products soaked surfaces are made with no dead spots, smooth internal transitions, and no bolted connections to allow ideal cleanability utilizing CIP programs and best inspection subsequent the cleaning process. The filters have an openable filter foundation offering immediate access to the filter internal parts for cleansing and inspection.


Promas Agitated Nutsche Filter Dryers are designed to satisfy all the requirements and are ideal for a vast variety of prescribed drugs together with good chemical applications. Our devices are suited for secure environments, and we have customised styles for cleanroom installation. Agitated nutsche filter dryer (ANFD) is pre-configured gear for multi-merchandise pilot-scale screening. It is a transportable filtering system that is simple to set up and use. When in contrast to custom-created gadgets, the standardised style eliminates the cost.

The pharmaceutical sectors depend on the right systems and companies for filtration, drying, and agitation. Our in-property producing capabilities encompass a broad assortment of equipment, programs, and characteristics that enable us to offer substantial-efficiency and expense-powerful functions procedure solutions.

Working Basic principle


The common consideration to layout information tends to make it feasible to simplify the device validation. The agitator is supported from the top and is externally put in on the stirring, the covers and the shaft seal. The shaft sealing is with a mechanical double display screen and a fastened bellow. The agitator’s arms are equipped with a particularly made area and drive the cake on the reverse clockwise rotation and combine and stir the cake on turning in the reverse path.

Simultaneous circular and vertical motions of the agitator lead to an very successful mixing of the complete model mass for the mixing and drying process. The arms of the agitator are S-formed for much better release of the merchandise. All soaked merchandise surfaces are heated to attain the greatest heat trade spot feasible, ensuing in swift drying occasions and low final humidity.

Operating Sequence

The agitated nutsche filter dryer includes innovative valves and hydraulics manipulation this sort of that recent installations are entirely automated.

Filtration Procedure

The slurry is poured into the filter, and strain is applied to displace the filtrate, leaving the cake on the filter media. There is a chance of segregation in slurries with a broad distribution of coarse rapidly settling solids and sluggish settling fines, with the finer fraction settling in excess of the coarse. Because the particles seal the cake and inhibit its manufacturing, keeping the slurry suspended with rotating arms during filtration aids in the development of a uniform cake.

Washing Cake

For the duration of the washing phase, the clean liquid is used to the cake via a spray ring or connections on best of the cover. One of the advantages of utilizing the Nutsche Filter is that it makes it possible for you to clean the cake’s surface area before spray washing it, making sure that the whole mattress is uniformly cleaned. In a multi-washing system, washing efficiency can be enhanced even much more if air or fuel is not permitted to join the cake, so the clean liquids regularly displace the treatments in a piston-like fashion.

Drying Method

Air or gasoline purges the product during the drying phase until the trapped dampness is decreased to an asymptotic stage, at which stage the cake is deemed as dry as possible. The cake is smoothed by alternating the rotation of the paddle or auger arms and implementing controlled stress to its surface with the hydraulic system to obtain the lowest achievable humidity content material. This helps prevent air or gas from escaping the mattress by sealing cracks in the merchandise.

Drying in the Vacuum

Scrape and de-lump the item even though slowly rotating and reducing the paddle arms to additional minimize merchandise moisture. To make the most of the Nutsche Filter’s drying abilities, take into account heating elements like the vessel, filter ground, and paddles.
