Now that more brothers and sisters are using closed loop LPG and EtOH extraction systems at subzero temperatures, questions regularly arise as to how much […]

There is a lot of discussion about which recovery pump is best suited for our application and my first thought is to ask which one […]

While I first shared the Terpenator design on 2-7-2011 on both SPR and IC Mag, and subsequently the fully automated Mk II, it was really […]

In answering process questions via email or at other forums, one cropped up that I thought I might share.  That was how do you process […]

A discussion of extraction column design would not be complete without first discussing subzero extraction.  As the LPG cannabis extraction process has evolved, we’ve learned […]

I recently got a call querying the details of how we automated the extraction process on the WolfWurx Mk VA2’s, but the story actually predates […]

Besides the highly individualized hand jive style of extraction using a screen, the question arises as to how much support we might expect from music, […]

There are a couple divergent lines of thinking with regard to BHO extraction.  In Plan A, we chill the LPG low enough to minimize plant […]

As the temperature of LPG drops, so does its pressure.  The Engineering Tool Box offers a handy reference showing the pressure of different mixes at […]

Sooooooo, why not passive SCFE CO2 extraction!  The sabriousness of CO2 certainly makes it attractive, and C02 becomes supercritical at only about 31C/87.8F at 1073 […]

The optimum material from which to build an extractor system has to address chemical compatibility, strength of materials, and compliance to food service and pharmaceutical […]

Dry sieve is a process by which the trichomes are broken off and sifted through a screen, allowing separation of the resin bearing trichomes from […]

I got my idea for the Grinning Reaper design, based on the short-lived Resin Reaper that briefly appeared in the market place, and Roger, a […]

Tumbling is a good way to process large amounts of material on the sidelines, while you occupy yourself with other chores or frolicking in play.  […]

Easy to get spoiled by an electric nail!  I know I sure have starting with the one mockup Growgeek and I assembled, which led Son […]

Induction heating has been around for a while and is used extensively to melt metal in foundries.  The advantage is the rapid heat up and […]

 One of my associates with a compromised immune system asked me to help her find an easier way to dip her plants for Spider Mites, […]

For those of ya’ll with higher volume or whom need your Terpenators to stay on like pumping out concentrate, here is a design I did […]

Not only does a vacuum chamber or vacuum oven speed things up, but there are some things that you need one to accomplish.  For those […]

For ya’ll brothers and sisters looking to process larger quantities at a time, we recommend that you consider the Subzero Ethanol process, by which either […]

For those of ya’ll coveting a vacuum oven on a limited budget, here is how we upgraded a used NAPCO 5851 vacuum drying oven to […]

Haskel now offers their EXT-420 plumbed so that you can run it in either single or double stage, depending on where volume or pressure are […]

 Here’s a real slick DIY seed separator shared with us by our UK brothers at Real Seeds: http://www.realseeds.co.uk/seedcleaner.html

For ya’ll that have been wondering what the different sanitary clamps are rated at, here is a handy chart.  They are for you convenience only […]

Still with 60″ packed Reflux column in operation In previous articles 10.19 190 Proof Ethanol from Scratch, and article 15.8 Ethanol Fractionating Still, I discus […]

Ethanol is hygroscopic, so picks up water in the extraction process, and there are limits to how concentrated a pot still can keep keep the […]

The simple pot still comes to us from simple roots buried in antiquity, but consists of a vessel that you can boil liquid in, and […]

Some of the professional engineering services certifying cannabis extraction equipment require that the collection pot have a certification placard attached and we’ve approached that a […]

Here is an article by Siskiyou Sam about a DYI rotary evaporator that he designed and built, and which he originally gave us permission to […]

Rotary evaporators are a keen thing to have if you’re running much alcohol, but alas the good ones are handsomely priced and finished material is not […]

We used a couple different heat exchanger designs at WolfWurx, depending on application.  One was the Tri Coil HEX, which we built ourselves using a […]

 The other HEX design that we use is the counter flow design, which in our case is a 20′ 1/2″X .049 wall 304SS tube inside […]

Here is a sweet little heat exchanger for recovering ethanol.  I made it out of a stainless salad bowl, a bulk head fitting, and a […]

During the time frame that I introduced the Mk III, I introduced the Lil Terp Passive extractor, which was based on the Mk III design, but […]

Success has many fathers, while failure is often a bastard child, so stories abound about how closed loop BHO extraction got started.  Truth is also […]
