Production Scale

Our unique internationally patented Continuous Carousel Filtration or 'Flow Chemistry' systems are at the cutting edge of modern chemistry technology. They are designed to enhance your key protocols and efficiencies in Fine Chemical,  Pharmaceutical and Laboratory processing.

​

Continuous Filter Dryer systems automatically filter, wash, dry and discharge solids in a continuous manner. The versatility of Continuous Filtration's ability to continually loop process smaller amounts of APIs in 3 to 4 minutes from slurry to dry cake with precise repeatability, yet still being able to produce larger quantity production scale throughput - makes it highly suitable for both APIs & HPAPIs. Continuous Filtration is a contained, safe and highly controlled way to process hazardous or valuable ingredients or HPAPIs highly potent active pharmaceutical ingredients. 

Protocols

​

  • No mechanical agitation damage or crystal shear

  • Reliable consistency in cake filtration

  • Accurate repeatability of washing parameters

  • Atomisation nozzles dispense wash solvent preventing disturbance to the cake

  • Thinner cake height technology, typically 10 - 30 mm

  • Improved wash efficiency!

  • Local HMI or DCS control system allows for safe operation

  • Integrated alarm systems for automated continuous operation

​
