Challenges with Process Scale Up in Cannabis/Hemp Extraction



What can make scaling up your process so difficult?

There are lots of things that can lead to the problems individuals experience when scaling up their procedures. These issues are not one of a kind to the cannabis/hemp field, but they are exacerbated by the effects produced from decades of Reefer Madness. In my time operating in the cannabis/hemp house, 15+ a long time, I have seen established equipment suppliers and sellers of laboratory supplies, like Sigma-Aldrich (now Millipore-Sigma), Fisher-Scientific, Cerilliant, Agilent, and other people, go from reporting men and women inquiring about qualified reference materials to environment up total divisions of their providers to company the requires of the marketplace. Progress. But we are continue to a fledgling marketplace experiencing a lot of challenges. Let’s glimpse at a number of distinct to approach scale up.

Darwin Millard will supply a presentation on this matter during the Hashish Extraction Digital Conference on June 29. Click on here to understand much more.Machines Availability: Deficiency of out there devices at greater and much larger procedure scales can seriously impression job timelines. Building not only machines acquisition hard, but also restricting the quantity of dependable machines makers you can function with.

Non-Linear Expansion: Never presume your process scales linearly. Maybe one of the most avoidable problems in the course of method scale up. You will rapidly locate that for quite a few processes you cannot just place in a greater unit and count on a proportional increase in output. This is since as system devices raises so to have to utilities and other supporting infrastructure, but not only that, process vessel geometry, proportions, and structure are contributing variables to approach efficiency as your scale of operations improves.

Hazardous Material Portions: Just as crucial to the system as the devices are the solvents and reagents made use of. As your scale of functions increases so does your demand and production of hazardous products solvents such as carbon dioxide (CO2), ethanol, and liquid petroleum gases (LPG) like Butane and Propane are obvious hazards, but so much too are the refrigerants made use of in the chillers, fuels utilised to power turbines, steam developed to warmth crucial techniques, and effluents and wastewater discharged from the method and supporting methods. Not just about every municipality needs countless numbers of gallons of flammable substances and harmful squander getting generated in their backyard…

Contractor/Seller Misrepresentation: Finding out in the middle of you venture that your contractor or equipment vendor has under no circumstances set up a technique at this scale prior to is hardly ever a great experience. Regrettably, contractor and seller misrepresentation of qualifications is a frequent prevalence in the cannabis/hemp house.

If all this was not negative enough, all much too usually the consequences of poor arranging and execution are not felt till your job is delayed or jeopardized owing to misallocation of funds or undercapitalization. This is especially accurate when scaling up your generation capability. Now let’s look at some ways to stay away from these mistakes.

The Rule of 10

When scaling up your method, Under no circumstances presume that a straightforward linear growth of your course of action train will be enough. It is frequently the circumstance that approach scale up is non-linear. Utilizing the Rule of 10 is a single way of scaling up your process by means of a stepwise iterative tactic. The Rule of 10 is ideal stated by means of an illustration: Say you are carrying out a bench-prime extraction of a couple grams and want to scale that up to a couple thousand kilograms. Right before jumping all the way to your remaining method scale, commence by having a lesser soar and only raise your bench-leading procedure by a component of 10 at a time. So, if you ended up delighted and self-confident with your results at the tens of grams scale, accomplish the similar method at the hundreds of grams scale, then the 1000’s of grams scale, tens of kilograms scale, and so forth until eventually you have validated your course of action at the scale of functions you want to obtain. By using the Rule of 10 you can be certain that your method will realize the very same yields/success at more substantial and much larger scales of operation.

Scaling up your procedure by way of an iterative method enables you to detect method troubles that usually would not have been discovered. These can incorporate (but by no implies should really be considered an exhaustive checklist) improper warmth transfer as system vessels enhance in sizing, the inability to manage procedure parameters owing to inadequately sized utilities and/or supporting infrastructure, and reduced yields than anticipated even while preceding iterations were being prosperous. On the other hand, this kind of solution can be pricey, primarily when thinking about tailor made course of action tools, and not every processor in the hashish/hemp room is heading to be in the position to use resources like the Rule of 10 and as a substitute need to rely on claims built by the products seller or manufacture when scaling up their course of action.

The Cannabis/Hemp Particular Process Machines Trap

How lots of instances have you heard this just one before: “We have a piece of procedure devices tailor-created to perform X,Y,Z job.”? If you have been around as extensive as I have in the cannabis/hemp area, almost certainly fairly a few times. A huge red flag when considering gear for your enlargement job!

Unless of course the gear producer is straight doing the job with hashish/hemp uncooked products, or with partners who procedure these objects, during product progress, there is no way they could have verified the tools will work for its purported use.

A great instance of this are ethanol evaporation programs. Most producers of evaporators do not perform with the volumes of ethanol they claim their systems can recuperate. So how did they arrive up with the evaporation charge? Short respond to – Thermodynamics, Warmth Transfer, and Fluid Mechanics. They modeled it. This much floor space, as well as this much heat/strength, with this a lot stress (or lack thereof), making use of this style of fluid, moving by means of this form of materials, at this charge of pace, gets you a 1000-gal/hr evaporator or some other theoretical value. But what is the authentic amount the moment an ethanol and cannabis/hemp resolution is working via the method?

For a straight ethanol program, the theoretical products and experimental types are pretty identical – particularly because individuals like liquor – substantial genuine-globe details for ethanol programs exist for reference in coming up with ethanol evaporators (much more accurately explained as distillation programs, i.e. stills). The same are not able to be reported for ethanol and hashish/hemp extract devices. Whilst it is legitimate that lots of botanical and ethanol units have been modeled, both equally theoretically and experimentally, owing to prohibition, facts for cannabis/hemp and ethanol programs are lacking and the details that do exist are principally restricted to bench-top rated and laboratory scale eventualities.

So, will that 1000-gal/hr evaporator strike 1000-gal/hr when it is jogging below load? That’s the actual question and why making use of products with founded general performance skills is crucial to a thriving course of action scale up when owning to count on the promises of a seller or equipment maker. Other than this is but another “catch 22”, since the set up, operational, and general performance qualification course of action is an high priced endeavor only a several machines makers servicing the hashish/hemp market place have carried out. I am not saying there are not any dependable tools sellers out there there are, but always request for info validating their claims and accomplish a vendor qualification prior to you drop seven figures on a piece of method gear on the phrase of a salesperson.

Essential Takeaways

Incorrect design and style and insufficient facts regarding process efficiencies on larger and much larger scales of manufacturing can direct to costly blunders which can prevent jobs from ever having off the ground.

Every single component of the producing course of action should be regarded as independently when scaling your system educate simply because each and every component will contribute to the system’s output, possibly in a limiting or expansive capacity.

I go further more into this matter in my presentation: Challenges with Procedure Scale Up in the Hashish/Hemp Business, later on this thirty day period through Cannabis Industry Journal’s Extraction Virtual Conference on June 29th, 2021. Right here I will provide real-environment examples of the penalties of incorrect system scale up and the importance of tools specifications, certifications, and inspections, and the significance of vendor skills and the genuine expense of improper style and design requirements. I hope to see you all there.

Until eventually then. Are living long and approach.
