To put my two cents in… The ccell has been my top choice for cart performance so far, I’d recommend it over any others at the moment.
Came across this research paper on the safety of some common cutting agents:
Carbonyl Compounds Produced by Vaporizing Cannabis Oil Thinning Agents
William D. Troutt, Matthew D. DiDonato
TLDR;
“Results: Analyses showed that PEG 400 produced significantly higher levels of acetaldehyde and formaldehyde than PG, MCT, and VG. Formaldehyde production was also significantly greater in PG compared with MCT and VG. Acrolein production did not differ significantly across the agents.”
As far as homogenization goes I may be a bit bias but it comes from trying out different methods until finding the fastest, easiest, repeatable process that I use now.
Heated Mag Stir Bar:
Pros - Cheap, Simple, Quiet.
Cons - Heat (Loss of volatiles), can take hours, cannot begin mixing until viscosity drops significantly, cant mix powders/solids, low uniform potency
Ultrasonic:
Pros - Particle size reduction, Great for low viscosity liquids, Easy cleaning, Moderate Price. Cons - Hot spots (material degradation/oxidation), limited viscosity range, cant mix powders/solids, Loud
Rotor-Stator:
Pros - High shear, Fast, Cheap/Moderate Price.
Cons - Limited viscosity range cannot mix high viscosity materials (distillate) without preheating, Incorporates air, can’t mix powders/solids, difficult to clean
SpeedMixer DAC:
Pros - High/Low shear, Fastest mixing, Any viscosity, No-Preheating necessary, No clean up, Particle size reduction, Can accomplish multiple processes, Can use vacuum with/without inert gases, Quiet.
Cons - Higher Price, Heavy, Essentially only accessible for commercial applications, Models top out at 10kg capacity
As I’ve recently posted, I am affiliated with SpeedMixer and understand the scrutiny I might encounter stating such but we do cart mixing all the time. Generally for carts its just terp/distillate with no cutting agents with full homogenization reaching 97%+ uniform potency (RSD) in around 3 minutes.
