Video: Nutsche Filter Dryers for Producing Cannabinoid Isolate

In this video, Pope’s Process & Sales Engineer, Ben Kultgen, introduces Pope’s Nutsche Filter-Dryer for the final isolation of cannabinoids.

Many cannabinoid isolates are created by taking a distilled extract, combining it with a solvent, and then using temperature change or evaporation to create a slurry of formed crystals and solvent.

The Nutsche filter dryer comes into play after this slurry is created. The slurry can be transferred into the Nutsche where the filtrate, also known as mother liquor, is forced through a bottom filter disc, resulting in a wet cake of crystalline cannabinoid. The Nutsche Filter-Dryer is more diverse than a simple filter as it also has a spray nozzle to allow for the isolate to be washed with a clean solvent, a liquid jacket for controlled heating or cooling, pressure capability for the efficient discharge of solvent, vacuum capability for drying solvent out of the filter cake, (aided by heat).

The design of the Nutsche for cannabinoid processing can include a special raisin/lowering full diameter cake agitator to assist the release of crystal surface impurities during washing and breaking up cake lumps to assist in efficient drying.

The Nutsche Filter-Dryer design provides an efficient single-vessel location for several process steps to occur with containment, eliminating contamination and exposure and unnecessary extra handling,

Isolation with Crystallizing Reactors | Nutsche Filter-Dryers

Pope Nutsche Filter-Dryers are known and used worldwide for final purification of pharmaceutical intermediates, high purity fine chemicals and other critical applications. Pope Reactors and Vessel Systems have been utilized for decades in the same industries. In many cases, Pope supplies reactors utilized for crystallization and a companion Nutsche for filtering, washing and drying the crystal slurries transferred from the reactor.

The advantages of pairing a reactor and Nutsche Filter-Dryer include:

  • Each vessel is optimally designed for performing these two different processes
  • Saves time by having both processes running simultaneously
  • Can be performed with no open handling of the raw material or slurry

Isolation is a critical operation, and often the final step in the entire manufacturing process. Pope Scientific’s Nutsches are preferred-proven for CBD crystalizing isolation to 99.9%, with less than 0.3%, to undetectable THC levels.
