frequently asked questions

 

Why distillation?

Distillate is the best starting material for nearly every product you would want to make and gives you the best chance at controlling the outcome of your product on a much more consistent basis.

Distillation is also a great way to utilize otherwise un-marketable product. Crude oil is everywhere in a manufacturing facility and can be collected in numerous ways such as cleaning your extractors internal lines, bottoms of hard to reach flasks, material columns, etc. This material is not a shelf-worthy product on its own and is usually discarded. However, once filtered and decarboxylated, this material can then be distilled into a highly valuable batch of oil that can then be infused into almost any product.

Why Glass?

Glass construction ensures full visibility of the distillation process, allowing your team to monitor operations and diagnose issues as they arise, ensuring more time for processing. New glass also has the added benefit of a virgin smooth surface that will not degrade and is easily traveled by viscous oil. Additionally, seamless glass connections with jacketing eliminating the need for additional heat to properly run through material.

Our units offer a patent-pending hybrid evaporator design, combining the benefits of glass with the strength of AISI 316 Ti steel.


What is the difference between scroll pump and rotary vain vacuum?

Rotary pumps utilize oil which is constantly contaminated by volatile solvents, wreaking havoc on operations. The scroll pump uses no oil and its functionality is unaffected by routine exposure to these solvents.


What is the difference between Thin Film and Wiped Film Distillation?

Thin Film and Wiped Film are two phrases generally used to describe Fractional Distillation— the act of separating a mixture into its individual component parts (or fractions). The process of distilling cannabis oil consists of pulling a vacuum to alter the vapor point of your input material without using excess heat. The oil feeds into your evaporator where a rotor, and blades/rollers then spread your input material thinly over the evaporator surface. This dispersion causes the targeted compound to vaporize off and collect in a separate vessel, free of almost all impurities.


What is Short Path Distillation?

Short Path is a distillation technique and refers to the oils short residence time in the evaporator. When coupled with low pressure and precise thermostat control, it allows for reliable, continuous processing of viscous, temperature-sensitive materials with little to no degradation.


What is Decarboxylation?

Decarboxylation is the process of removing a carboxyl group from the compound, which releases CO2.  Energy is directed into the refined oil from Solvent Recovery, typically through heat. The carboxyl group in the molecular structure of THC-A prevents raw ingestion of the plant and the ability to experience psychoactive effects. Heat, time, and agitation is applied to remove this compound and convert its bioactive constituents. The resulting material can then be consumed through a number of different ingestion methods.

The Prescott Multi-Stage offers integrated Decarboxylation, allowing for increased throughput with limited transfer loss between sub-processes. Otherwise, our base-level distillation units can be paired with other Decarboxylation systems. We work closely with our reseller partners to find the correct recovery option that fits our clients needs.


What products can I make with your distillate?

Distillate is most commonly seen in pen style vaporizers, but distillate is the cleanest starting material for nearly any product you would want to make.

Please contact our sales team to learn more about the broad range of formulation solutions we offer to build out your product line.


What can I expect in terms of Throughput?

Throughput is dependent on parameters and proper post-processing of the material, along with other variables that may drive your processing goals. We recommend speaking with our technical teams to walk through your specific processing needs and the operating range of our equipment line.


Does starting material matter?

The quality of the starting material will directly drive the potency and throughput of your end product. We suggest properly filtering, decarboxylating, and degumming of any crude material intended for distillation. 

The Prescott Multi-Stage offers integrated decarboxylation and solvent recovery, simplifying the material preparation process and limiting transfer loss between these sub-processes.


Does material really require two passes through the distillation unit?

Yes. The first pass will separate your thinner terp-rich distillate fraction, while the second pass will collect the bulk of your cannabinoids. Both passes can be done on one unit, but will be significantly more efficient through two units (one dedicated to first pass, one dedicated to second pass). 

The Prescott Dual-Stage and the Prescott Multi-Stage both include two distillation units connected in-line, allowing for increased throughput and fewer gaps in processing time.
