When the extractor has been properly shut down, it’s time to disassemble it and reveal the cannabinoid alchemy you’ve performed, turning solid green plant matter into a concentrated liquid gold $)

Who We Are

HempHacker.com is supported by Orion GMP Solutions, LLC. We write on this open-source platform to share our thoughts on the standardization of cannabis manufacturing.

We have a team of experienced scientists and engineers, with backgrounds in Department of Defense Consulting, Aeronautical Engineering, Organic Chemistry of Natural Products, Plant Biology, and Pharmaceutical Manufacturing.

We bring our perspectives and direct experience with standardized cannabis manufacturing to our readers, hoping to give something to the international cannabis community in return for the great opportunities is has provided us.

What We Do

We are constantly involved with the international cannabis community. We speak to groups around the world about standardized cannabis manufacturing, with the full intention of ensuring social equity in the process. We work with small farmers up to publicly traded corporations. We adjust our price based on what is a fair an equitable price, and we deliver what we say we will.

Our entire group participates in the ASTM D37 Cannabis Standards Committee, where Andrew serves as the chairman of the Quality Management Systems Committee. We work by helping our clients implement standards, preparing them for GMP audits, and we are proudly the first cannabis consulting firm with a focus on Good Manufacturing Practices for Cannabis.

How We Do It

We engage with clients in a number of ways. You will most likely see us at ASTM D37 Cannabis Standards events, the Cannabis Science Conference, CannaTech, and the MJBiz Daily Conference. Many clients started off with us through email, just asking simple questions that we have quick answers to. Either way, we like to get out and meet industry stakeholders and see where there are synergies for business.

Once we get to know our potential clients, we work through the fundamentals: business plans, project management plans, financials. We help answer the questions, like: “is this a good idea?” Once we establish that our goals are aligned, we work with our clients through gap audits, GMP Implementation plans, GMP and Quality Management Implementation, GMP Training, and Certifications audits to their preferred standards.

Once the extraction collection chamber reaches the desired pressure under vacuum, it’s ready to shut down. Shut down always starts with stopping the flow of butane – i.e. turning off the recovery pump.

After running the continuous shower, the liquid butane is pulled off into the gas phase by the recovery pump and pushed into the liquid phase, which then fills back into the recovery cylinder. The push/pull method of recovery requires heating the extraction collection vessel (10) and cooling the recovery cylinder (5). The recovery cylinder can be cooled to -50C if you use a dry ice/ethanol bath, but is not necessary – it just speeds up the recovery. Push/pull is governed by the most useful branch of chemistry – thermodynamics – we’ll explain that at a later time if anyone is interested…

After the desired amount of time running the continuous shower, the process needs to be shut down. The process can transition directly to the recovery step, but first make sure that no unsafe conditions exist. Since this puts several pounds of butane into the recovery cylinder, the process is inherently dangerous. Take your time and make sure every valve is open or closed as it should be.

Continuous showers are the easiest and most efficient way to extract cannabinoids in a CLS. The butane is recycled by being pulled out of the bottom of the collection chamber, in the gas phase. It then passes through the recovery pump, up the the recovery manifold, and is condensed into the liquid phase by keeping the high pressure side of the recovery manifold (3) at ~100PSI.

Once the extractor has reached maximum vacuum and no leaks have been detected, it can be filled with butane.
