Butane Hash Oil’s Quality Is Largely Determined By The Quality Of Vacuum Oven Used During The Purging Process
The popularity level of butane hash oil (BHO) is growing exponentially. BHO (or ‘dabs’) has been around for a long time, but in the last five years it seems like everyone I know is either consuming BHO for the first time, or consuming it more, or they making it themselves. I have a handful of friends that I would consider to be true BHO experts. My criteria for BHO expert is simple – if my mouth salivates when I think about your BHO, you are an expert.
If you are a BHO fan, you have likely seen quite a bit of low grade BHO. It’s grey in color, tastes awful, and makes you say things like ‘is this safe to consume?’ While there are many factors that determine the quality of BHO, one of the largest contributing factors is the quality of vacuum oven being used during the purging process. Almost anyone can get quality pre-run these days, and almost everyone can blast properly. However, if people don’t have a proper vacuum oven for purging their product, there is so much undesirable material left behind that it ruins the BHO.
A lot of rookie BHO makers that I know have really cheap BHO vacuum ovens, or no ovens at all. The ones that do have ovens have cheap BHO vacuum ovens that they got off of the internet from E-bay or Craigslist that are made in China. I understand that starting out can be expensive, but skimping on your BHO vacuum oven only hurts your product and reputation in the long run. And as more and more BHO makers step up their equipment, you will be left behind.
The BHO consumer is becoming pickier every day, and they will only consume BHO that has been properly purged using a high quality BHO vacuum oven. I know I’m picky when it comes to BHO; pickier than I am with flower. If you make BHO, and you are trying to take your BHO to the next level, make sure you have a quality BHO vacuum oven.
I recently toured a facility where they make BHO vacuum ovens, at a company named Cascade Tek. Unlike cheap BHO vacuum ovens that are made in China, these are made in the United States, right in my home state of Oregon. Unlike other vacuum ovens that were designed with other purposes in mind, these vacuum ovens were designed with BHO extraction in mind. The result from using their oven is an end product that is better than anything else I’ve ever consumed before. More about their vacuum ovens below, courtesy of their website:
The Most Effective Turnkey Solution for BHO Extraction
Since 1992 we have been building vacuum ovens and understand the specific challenges associated with production-scale, high-volume BHO Extraction.
Why Use A Vacuum Oven?
Large-Scale Extraction. The key to thorough solvent extraction is surface area. You need to have considerable surface area to off-gas solvents like butane. Our smallest vacuum oven, (TVO-2) offers over four square feet of processing shelf space. Processes in a tank or vat are extremely inefficient and will produce incomplete purging of the product. The TVO-2′s three solid shelves accommodate multiple Pyrex dishes and vacuum allowd the extraction at uniform low temps.
Temperature Uniformity. The most difficult temperature range to control is just close to ambient. Vacuum ovens control low temps evenly. Anything other than a vacuum oven can produce hot spots and temp spikes that can destroy microceuticals and ruin your product.
Why a Chemical Duty Vacuum Pump?
Butane Ruins Pumps. Chemical duty pumps offer the flexibility of using a trap to collect Butane for reuse and /or disposal or exhausting to a safe location. Oil sealed pumps require use of a foreline trap because utane will destroy the internal workings of the pump. Chemical duty pumps are not destroyed by butane and eliminate the need for a foreline trap.
The Ideal Pressure. The ultimate pressure of the pump we recommend is 1.5 torr. Any lower vacuum and substances like Delta 9 THC will “boil off” and that’s bad.
