Frequently Asked Questions

Filtering Centrifuge

If you are processing APIs; AI; highly potent ingredients; or toxic, flammable, or reactive materials, then it is best to have a machine that can be fed, operated, and discharged while in a completely enclosed process system. This protects your employees, the product, and your facilities.

Automatic discharge is safer and has an enclosed/sealed process area. It can protect your employees from the process and protect your product from the environment. Automatic discharge also means higher plant capacity – you can run several batches an hour without the need for manual labor. Even though automatic discharge is a more expensive option, if you do not change the product often, even if you do not need an enclosed space, there could be cost savings from a labor standpoint.

If it is safe to handle your product manually, manual discharge is the economical option, but it does take more time between batches. This could reduce your overall output of product. However, if there are a lot of product changes, the manual discharge option allows for closer operator oversight to manually observe and control the process.

The horizontal design is a newer technology that provides more even feed loading for higher quality filtration and washing, and creates less vibration. This design is also conducive to horizontal plant layouts. Our horizontal machines include the Pharma Peeler Centrifuge, the Inverting Filter Centrifuge, the Chemical Peeler Centrifuge, and the Starch Peeler Centrifuge.

A vertical design is conducive to vertical plant layouts. It is also a more economical option. Our vertical machines include the Vertical Basket Centrifuge – Bottom Discharge, the Vertical Basket Centrifuge – Top Discharge, and the Nutsche Filter Dryer.

The Pharma Peeler Centrifuge is the most common, effective (highest G factor for the size), and efficient for Pharma and other GMP applications like Food and Beverage.

The Chemical Peeler Centrifuge is the most common, effective, and efficient machine for chemical and non-GMP applications.

The Inverting Filter Centrifuge can handle the most difficult materials to filter. Common problems with sticky or compressible products can be solved by using an Inverting Filter Centrifuge.

The Vertical Basket Centrifuge – Bottom Discharge has the largest available filtering area. Our current largest model is the 1850/1250 which has a filtering surface area of 7.26m2. However, we are always innovating. Let us know if you require different sizes for any of our equipment.

The Vertical Basket Centrifuge – Top Discharge is our most simple and economical machine. Due to its simplicity, it is quite versatile as well. But you do not want to just buy the machine with the lowest CapEx. Make sure the machine will suit your filtering needs by reading more about it here and contacting our engineering professionals directly.

Our machines that achieve the highest level of dryness include the Pharma Peeler Centrifuge, the Chemical Peeler Centrifuge, the Starch Peeler Centrifuge, the Inverting Filter Centrifuge, and the Nutsche Filter Dryer. You can narrow down the correct machine for your process by visiting our comparison tables or contacting our engineering professionals directly.

Filter and Vacuum Drying

The Nutsche Filter Dryer filters, washes, and dries in the same machine. This can help lower CAPEX and OPEX costs and may be more suitable for plants with condensed floorspace. Product losses are minimized because material isn’t transferred between machines . It also reduces handling risks.

Our expert designers and fabricators have many years of experience eliminating the concerns of FOB, especially around moving parts. For example, no bolts or nuts are allowed inside the process area, and agitators are fully welded.
Glove boxes can be added to the discharge of the centrifuges, nutsche filter dryers, or vacuum dryers.
Isolators contain potent or toxic products from operators and the environment, especially when handling dry materials.
