S2 Engineering (S2) provide a full turnkey service for Agitated Nutsche Filter Dryers (ANFD's) from design and manufacture to assembly, installation and commissioning.
Our ANFD's are innovatively designed and engineered to help improve plant operational processes efficiency. We can also provide ANFD's with barrier isolator (Glove box) technology for contained discharge and/or charging operations.
We are experienced in process media filtration and drying performance and provide equipment with high levels of safety and quality that meets all appropriate industry regulations.Our ANFD's feature a differential mixing agitator and paddle that moves vertically for a thorough mix performance. The filter drier agitator consists of a series of sharp curved blades that achieves mixing penetration into difficult cakes without undue product stress. While moving and lifting the cake media around the internal clearances within the filter dryer, agitation mixing efficiency is achieved through differential velocities.
Agitated Nutsche filter Dryers (ANFD) is a filtration technique used in applications such as;
S2's is part of a Group of Companies which includes Schematic Engineering Industries - a leading supplier of barrier isolators. As such, S2 is able to supply their ANFD's with an integrated barrier isolator, as detailed below and shown in the photo.
Our ANFD Barrier Isolators have the following features;
S2 provide ANF's with an integrated Dryer, to optimise production efficiency. This is termed an ANFD. The ANFD multipurpose agitator and drying solution with an unique feature being that the agitator performs a number of operations through movement in axes both parallel and perpendicular to the shaft.
This filter dryer was developed due to plant operator safety requirements and environmental concerns when processing solvents, particularly the issues surrounding solvent evaporation. The ANFD provides filtration under vacuum or pressure in a closed-loop system, a sealed vessel where solids can be discharged straightaway into a dryer. The key benefits of the S2 ANFD solution include;
Alternate Materials of Construction: In addition to various grades of Stainless Steel (304, 316 and 416), ANFD's can be supplied in a number of different materials of construction including Alloy 20, Titanium, Alloy 22 and Alloy C276 (Hastelloy C).
Chemical Resistant Coatings: Compared to exotic alloy materials, chemical resistant coatings provide a lower coat of supply solution when processing highly aggressive substances. Our StanCoat high chemical resistant coating is an example of such a coating and this is also conducive for food grade applications
