CBD Crystallization Equipment

What does a NiTech crystallizer look like?

NiTech® continuous crystallizers are manufactured to suit the required throughput rate and start composition of CBD distillate. Here are some example units (intermediate and larger sizes also available):

The DN15 Standard – Glass

The smallest unit: 
A laboratory/small-scale unit, with an output of ~ 0.9 kg/h of CBD isolate (crystals leave the COBC in a slurry to be filtered and dried downstream).

 

CBD Equipment – DN15 Standard Glass crystallizer

DN32 sch. 10s ATEX/C1D1 – 316L Stainless steel

A production unit:
Output of ~ 7 kg/h CBD isolate (crystals leave the COBC in a slurry to be filtered and dried downstream).

 

DN36 Atex stainless steel crystallizer for CBD

DN50 sch. 10s ATEX/C1D1 – 316L Stainless steel

A large production unit:
Output of ~ 12 kg/h CBD isolate (crystals leave the COBC in a slurry to be filtered and dried downstream).

Notes:

  1. Based on an example system of:
    1. 88 % w/w CBD in distillate;
    2. ~ 0.6:1 w/v distillate to heptane;
    3. 17 % w/w of 50 micron CBD isolate seed crystals added as part of a slurry;
    4. 50 minutes cooling time; and
    5. 0⁰C final temperature.
  2. “Net” CBD isolate production rate is quoted to account for the mass of CBD isolate crystals which must be recycled as seed material.
