Promas Engineer’s ANFD is geared up with a lot of characteristics pursuing the most recent designs and technology such as, equivalent ability filtrate collection receiver beneath vacuum, solvent, restoration, compact style, heating preparations, chilling arrangements, lifting & lowering. The filters are meant to satisfy extreme cGMP and Food and drug administration technical specs and demanding demands for filters utilised in the production of pharmaceutical factors. All items soaked surfaces are designed with out lifeless places, easy inner transitions, and no bolted connections to enable optimum cleanability utilizing CIP techniques and ideal inspection pursuing the cleaning method. The filters have an openable filter foundation supplying quick accessibility to the filter internal factors for cleaning and inspection.


Promas Agitated Nutsche Filter Dryers are developed to meet up with all the standards and are suited for a extensive selection of prescription drugs together with wonderful chemical purposes. Our equipment are suited for risk-free environments, and we have customised patterns for cleanroom installation. Agitated nutsche filter dryer (ANFD) is pre-configured equipment for multi-merchandise pilot-scale screening. It is a portable filtering program that is straightforward to established up and use. When in comparison to custom-built units, the standardised style gets rid of the cost.

The pharmaceutical sectors depend on the correct technologies and providers for filtration, drying, and agitation. Our in-house manufacturing capabilities encompass a wide variety of equipment, methods, and functions that permit us to provide large-functionality and price-efficient functions process options.

Working Theory


The standard interest to layout particulars can make it attainable to simplify the device validation. The agitator is supported from the prime and is externally set up on the stirring, the addresses and the shaft seal. The shaft sealing is with a mechanical double monitor and a fixed bellow. The agitator’s arms are equipped with a notably developed surface and thrust the cake on the reverse clockwise rotation and combine and stir the cake on turning in the reverse route.

Simultaneous round and vertical motions of the agitator direct to an really effective mixing of the whole model mass for the blending and drying process. The arms of the agitator are S-fashioned for greater release of the merchandise. All soaked item surfaces are heated to achieve the maximum warmth trade area feasible, resulting in swift drying instances and reduced greatest humidity.

Operating Sequence

The agitated nutsche filter dryer requires sophisticated valves and hydraulics manipulation such that recent installations are totally automated.

Filtration Procedure

The slurry is poured into the filter, and stress is applied to displace the filtrate, leaving the cake on the filter media. There is a possibility of segregation in slurries with a broad distribution of coarse rapidly settling solids and sluggish settling fines, with the finer portion settling in excess of the coarse. Because the particles seal the cake and inhibit its generation, maintaining the slurry suspended with rotating arms throughout filtration aids in the formation of a uniform cake.

Washing Cake

During the washing phase, the wash liquid is utilized to the cake by way of a spray ring or connections on best of the protect. A single of the benefits of utilizing the Nutsche Filter is that it enables you to clean the cake’s floor before spray washing it, making certain that the complete bed is uniformly cleaned. In a multi-washing method, washing effectiveness can be improved even much more if air or gasoline is not allowed to be a part of the cake, so the wash liquids regularly displace the solutions in a piston-like fashion.

Drying Process

Air or fuel purges the merchandise throughout the drying phase right up until the trapped moisture is decreased to an asymptotic level, at which level the cake is considered as dry as attainable. The cake is smoothed by alternating the rotation of the paddle or auger arms and applying regulated stress to its floor with the hydraulic technique to achieve the lowest achievable humidity articles. This stops air or gasoline from escaping the bed by sealing cracks in the item.

Drying in the Vacuum

Scrape and de-lump the product although little by little rotating and decreasing the paddle arms to additional minimize merchandise dampness. To make the most of the Nutsche Filter’s drying abilities, take into account heating components like the vessel, filter flooring, and paddles.
