By incorporating filtration‚ cake washing‚ vacuum drying and product discharge into a single unit‚ the Agitated Nutsche Filter Dryer eliminates the need for multiple handling and transfer steps between operations‚ reducing the potential for cross-contamination and improving efficiency․
The ANFD can be operated in both vacuum and pressure modes‚ permitting efficient solid-liquid separation and drying‚ the latter at lower temperatures when operating under vacuum․ While vacuum filtration has the advantage of low-temperature drying and potential use with heat-sensitive products‚ pressure filtration speeds up the rate of filtration and increases batch throughput․
This multipurpose agitator combines slurry mixing‚ cake leveling‚ washing‚ drying and product discharging in one operation․ It is driven by a controlled movement that ensures even cake formation‚ uniform heat transfer‚ uniformity of drying and maximum automation with minimum manual supervision․
The Agitated Nutsche Filter Dryer can be designed to be fully enclosed․ Processing materials under vacuum conditions can increase safety and remove material from the environment while eliminating contamination․ It also reduces emissions of particulates and vapors with improved operator safety when handling sensitive and/or hazardous products․
The filter also enables the recycling of these valuable solvents that would otherwise be lost to the atmosphere during the filtration/drying process‚ as well as easing the cost-effective and environmentally friendly production of the final product․
In addition‚ the jacketed vessel bottom sections and agitator system can provide accurate temperature control by circulating heated or chilled fluids‚ provide uniform temperature distribution‚ and help preserve the quality of temperature sensitive materials processed in the vessel․
To continuously meet strict hygiene requirements‚ the ANFD is designed with smooth‚ easy-to-clean internal surfaces and component shapes‚ and built to be strong and reliable to maximize performance and reduce downtime in even the most demanding industrial processes and environments․
Custom equipment for pharmaceutical‚ API‚ chemical‚ specialty chemical‚ or similar industries can be manufactured in accordance with GMP standards with custom capacities‚ automation levels‚ surface finishes and process specifications․
The pharmaceutical industry utilizes ANFDs to process active pharmaceutical ingredients (API)‚ drug formulations and intermediates․ ANFDs provide precise filtration and drying conditions in order to produce a quality product that is stable and pure․
Agitated Nutsche Filter Dryers are used in industrial processes for separating‚ purifying‚ and drying of chemical compounds‚ providing effective solid-liquid separation and solvent recovery in specialty chemical processing․
ANFD systems filter and prepare ingredients to meet the food quality and safety requirements of food based applications․ Therefore‚ the hygienic design of the systems meets food application standards․
ANFDs have applications in the beverage sector‚ where they are used to clear and purge unwanted particles and impurities present in the beverages and to increase the quality and uniformity of the final product․
ANFDs are used in the petrochemical industry to separate and purify crude oil components into individual products for the production of fuels‚ plastics and synthetic compounds with a high degree of reliability‚ efficiency‚ and consistency․
The Agitated Nutsche Filter Dryer is used to filter and convert raw materials into bio-fuels․ Its modular design allows for the safe handling of a wide range of materials from flammable‚ toxic and corrosive materials to heat-sensitive mixtures․
Designed for efficient solid-liquid separation of a product by means of vacuum filtration or pressure filtration‚ the ANFD achieves maximum product recovery‚ clean true filtrate and a homogeneous filter cake that could be put to good use in applications requiring a high degree of cost-effective filtration and a consistent end product․
The filter cake‚ or solid left over from the filtration process‚ can also be washed in place‚ in the same vessel it was produced‚ to remove impurities‚ remaining mother liquor‚ and any unwanted contaminants․ Thus‚ a higher product quality can be assured‚ while simultaneously requiring less handling and processing time․
The vacuum drying system also effectively removes the remaining moisture from the filter cake at low temperatures‚ protecting the physical and chemical properties of heat-sensitive final products while improving drying efficiency and saving operating energy consumption․
The equipment can be run under pressure to speed up the filtration process and improve solid-liquid separation․ This is particularly useful for liquid products with low filtration rates‚ resulting in improved throughput and reduction in total batch times․
Its totally enclosed design allows value-adding solvents to be recovered from the filtration and drying processes‚ reducing costs associated with their disposal‚ as well as environmental emissions and promoting sustainability․
A closed processing system is particularly useful when the material being processed is toxic‚ corrosive‚ flammable etc․ as they reduce operator exposure to the material and reduce the emission of harmful vapors to the workplace․
The ANFD reduces the moisture content of wet filter cakes to produce a dry powder suitable for packaging or further processing․ By controlling the drying‚ the risk of overheating is reduced‚ resulting in improved shelf life and reduced downstream drying equipment requirements․
The ANFD operates in a batch mode‚ performing filtration‚ washing‚ drying and discharge of the product in a single vessel‚ improving the batch-to-batch consistency‚ reducing the overall cycle time and increasing production efficiency․
An enclosed system does not permit contact or exposure with the outside environment throughout all stages of production‚ decreasing potential contamination and allowing products to comply with strict manufacturing quality and safety requirements used in pharmaceutical and API production․
The jacketed vessel and vacuum drying make the ANFD a suitable choice for drying heat sensitive materials‚ including those requiring preservation of some of their physical characteristics‚ or the isolation of the end products from thermal degradation․
Being fully contained‚ the equipment is very low in the product's exposure to ambient conditions and will find applications in the pharmaceutical‚ active pharmaceutical ingredient (API)‚ and specialty chemical industries where purity requirements are critical․
A closed processing system allows for solvent recovery during filtration and drying‚ thereby reducing solvent consumption‚ costs‚ emissions‚ and making the production more environmentally sustainable․
The ANFD is operated under vacuum or pressure and handles a full range of products with different filter characteristics‚ increasing filter effectiveness and reducing batch cycle times․
The fully closed design prevents hazardous and toxic vapors‚ dusts‚ particles and other solids and liquids from escaping into the workplace‚ helping ensure the safety of operators and compliance with industrial safety standards․
As the filtration‚ washing‚ drying and discharge all take place in the same vessel‚ this reduces handling‚ resulting in reduced product loss‚ reduced contamination risk and increased productivity․
The multipurpose agitator allows mechanical homogenization of the filter cake with the washing liquid during washing‚ and provides excellent heat transfer during drying; resulting in a much shorter drying time‚ lower final moisture content‚ and improved uniformity of product quality․
The ability to operate under an inert gas atmosphere also allows the ANFD to be used with substances sensitive to oxygen/moisture‚ flammability‚ and toxicity‚ which provides an added level of protection to the product and personnel․
ANFDs combine several process steps in one piece of equipment‚ resulting in reductions in equipment footprint‚ utilities usage‚ labor‚ maintenance requirements‚ and operating costs‚ which improve the equipment's return on investment․
The ANFD is designed for industrial processes and is made out of SS304‚ SS316L and other corrosion resistant alloys․ Its strong design‚ precision engineering and low maintenance requirements give it a long life even in harsh process conditions․
