Q: What mesh sizes are available?
A: 20, 10, 5, 1, 0.65,
Q: How cold do I need to go?
A: The colder the better. Take samples and experiment. -40 C is easy with many freezers.
Q: Do I have to filter more than once?
A: Using multiple filters in series can allow for single pass filtration
Q: How much can be filtered before I must replace a cartridge?
A: Cartridges are cleanable using an included brush system. Approximately 40 liters can be filtered before needing cleaning.
Q: How much solution can be filtered per hour?
A: Waxier oil will filter about 5 gallons an hour while cleaner oil will filter at about 10 gallons an hour.
Q: What yield can I expect from distilled CBD material?
A: Depending on input purity, you can expect between 60-75% yields on average.
Q: Does the material need to be winterized and filtered?
A: Yes it needs to be rid of as many fats and waxes as possible.
Q: Does the material need to be distilled?
A: It is highly recommended that the input material be distilled or be of a minimum 70% CBD.
Q: How much CBD can be produced in a shift?
A: Between 2 kg and 40 kg of CBD isolate can be produced in our reactors in a typical day.
Q: Does the material need to be winterized?
A: Yes, winterization is highly recommended.
Q: Does the extraction method matter?
A: No. Spinning band distillation can be paired with any method of extraction. Ethanol, CO2, and butane are the most common solvents.
Q: What purity can I expect out of the spinning band system?
A: Depending on the input potency, we see an average of 90% total active cannabinoids. Typical improvement is around 20% increase in cannabinoid concentration.
Q: How long does a full distillation take?
A: Load sizes can vary, but a medium sized batch takes around 8 hours from heat up to finishing cleaning.
Q: Is one pass really enough?
A: Yes! We see much greater separation than other distillation methods allowing us to reach higher purity with less work.
Q: Can useable terpenes be distilled?
A: Yes, you can extract and purify terpenes using the spinning band system. It is a slightly different process than cannabinoid distillation however.
Q: Are solvents needed?
A: The remediation process is solvent free. The only solvents needed are for cleaning between batches.
Q: Is the process automated?
A: The process is automated and software driven. The operator only needs to check the THC content in the reactor by HPLC occasionally.
Q: Can the operator choose the level of THC in the final product?
A: The process can make THC Free material or can be operated to make o.2% material or any other concentration of THC. The amount of residual THC is controlled by the operator.
Q: What consumables are needed?
A: Distilled water
Q: How does winterization affect remediation?
A: Correctly winterized material remediates more quickly than unwinterized material.
Q: Does material need to be decarbed before remediation?
A: Decarbing before remediation is not necessary. Decarbing will happened automatically as part of the remediation process.
Q: How does remediation work?
A: The software automatically controls conditions in the reactor to optimize the separation of THC from the oil into the water drum.
Q: Does water contact the oil?
A: Water never contacts the oil. Only the removed THC/CBD contact the water.
Q: Is anything else removed besides THC?
A: Some CBD is lost. Total cannabinoid loss is about 15% (including Delta9 THC)
Q: What happens to the minor cannabinoids?
A: Minor cannabinoids are retained in the oil.
Q: What are typical starting materials?
A: THC under 7% (1-3% sweet spot). Total cannabinoids in the high 60’s – low 70’s. Winterized crude or distillate will work.
