What are Nutsche filters?

Nutsche filters, also known as Agitated Nutsche filters, are industrial filters used for solid-liquid separation of suspensions by cake filtration. During the filtration process (either by pressure above or by vacuum below the filter bottom or by a combination of both) the filter cake builds up, which is constantly smoothed by the height-adjustable stirrer. The filling with suspension and the filtering can be repeated until the maximum filter cake height is reached. After completion of the filtration, it is possible to apply the washing cake to the filter cake or even to re-slurry it in the washing liquid and wash and filter several times. In filter dryers, the agitator is used during the drying of the filter cake for continuous movement of the solid to accelerate the heat transfer and drying. Agitated Nutsche filters can also be used for extraction with subsequent filtration.

There are some varieties like:

  • Pressure filter, agitated pressure filter, and stirring pressure Nutsche: A type of Nutsche filter that has filtration with overpressure through a filter medium.

  • Vacuum slide and agitated vacuum chute: A type of Nutsche filter that does filtration by an applied vacuum below the filter bottom. Recommended for highly compressible filter cake. A combination of overpressure above the filter bottom is possible.

  • Filter dryer and vacuum filter dryer: Combination of an agitated suction filter and a dryer. In the case of the filter dryer, the outer wall and in some cases also the stirrer is designed to be heatable. If the heating jacket is used as a cooling jacket, crystallization processes with subsequent filtration can also be carried out by using this process equipment.

Nutsche Filter Dryer: Operation Stages

The operation of nucha filters involves the following processes:

  • Product loading: The solid-liquid mixture to be processed is transferred into the vessel.

  • Filtration: Separation of the liquid phase through the filter medium, forming a cake. The agitator blades move the solid material against the filter, ensuring material homogenization. Pressure is applied to facilitate the process.

  • Solid washing: Fresh solvent is sprayed onto the cake to remove impurities. The washing process can be performed with the cake intact or by suspending the material with the help of the agitator blades. Liquid passage is facilitated by applying pressure or vacuum, as required.

  • Pressure drying: Moisture is reduced by introducing air or inert gas to pressurize and compress the cake.

  • Drying: The vessel walls and the agitator are heated. Vacuum can be applied to separate the solvent and reduce its evaporation temperature.

  • Solid discharge.

Advantages of using Nutsche Filters

Nutsche filter dryers are widely used in the production of additives, flavorings, essences, colorants, vitamins, plant or animal extracts, antibiotics, and biotechnological products in the pharmaceutical, chemical, and food industries. Advantages of using Nutsche filters include:

  • High solvent recovery rate.

  • Closed system that eliminates the possibility of releasing vapors into the environment. Ideal for processing toxic, flammable, highly volatile, or temperature-sensitive materials.* No risk of contaminating the solid cake.

  • Production of homogeneous products with high levels of purity.

  • Versatile equipment that can perform a wide range of operations, including mixing, filtration, redissolution, washing, pressurization, vacuum, and drying.
