CBD Crystallization Equipment
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 ~ 0.5 kg/h of CBD isolate (crystals leave the COBC in a slurry to be filtered and dried downstream).
DN36 ATEX/C1D1 – 316L Stainless steel
A production unit:
Output of ~ 8 kg/h CBD isolate (crystals leave the COBC in a slurry to be filtered and dried downstream).
DN43 ATEX/C1D1 – 316L Stainless steel
A large production unit:
Output of ~ 11 kg/h CBD isolate (crystals leave the COBC in a slurry to be filtered and dried downstream).

Notes:
- Based on an example system of:
- 65 % w/w CBD in distillate;
- ~ 2:3 w/v distillate to heptane;
- 5 % w/w of 50 micron CBD isolate seed crystals added as part of a slurry;
- 50 minutes cooling time; and
- (-15)⁰C final temperature.
- “Net” CBD isolate production rate is quoted to account for:
- The mass of CBD isolate crystals which must be recycled as seed material;
- A conservative estimate of 10% losses by mass during filtering/washing ; and
- A conservative estimate of 10% losses by mass during crystal milling.
