There are two ways to prepare butane for storage: The freezing recapture entails cooling the gas enough to store it as a liquid, while squeezing involves using pressure to return butane to its liquid state for storage. Use the vacuum pump on the extractor to perform the first purge. This is called a hot water bath and can be performed with open-ended systems as well. Heat is the enemy of extraction.
High temperature ruins shatter. Heat evaporates the terpenes that give great BHO its smell and flavors. Heat promotes hash decarboxylation, turning it into a dark oil suitable Orily for making edibles. Pay special attention to heat at all times. See Decarboxylation section below for further information.
After the initial purge, the material will no longer be a pool of liquid, or transparent, but rather more like a thick, goopy, runny toothpaste. You can take it out drier or wetter, depending on your goals of making shatter versus oil This pre-purged BHO scrapedjrom the versus edibles.
Fold the parchment paper into little parchment trays with two- to three-inch walls. Now it's time to apply gentle heat under low pressure to finish purging and processing the batch.
BHO is categorized by consistency, with shatter being the most prized. Next comes honeycomb, budder, wax, and oil. The goal at all times should be the lightest color possible and an extremely dry quality. Great shatter is clear like amber glass, contains no bubbles, and breaks at room temperature.
Honeycomb wax should be very pale, opaque, or translucent, dry and crumbly. Budder has more of a warm taffy quality to it, while oil is viscous yet tacky. Shatter Aim to make shatter. It's the hardest to make, requiring lower heat and a longer period of time in a vacuum oven. Temperatures and pressure can vary widely. Torr or mm Hg is a measure of pressure-which is the ratio of force to the area over which that force is distributed.
Torr or mm Hg refers to milligrams of mercury, but a more common measure in America would be pounds per square inch, or psi. Pressure mea-. Extractions made with buds only, ca!!
Across International makes a high-quality, entrylevel vacuum drying oven. At this point, the amount of residual butane in the solution is low so the butane is too diluted to explode. Use one that is designed to tolerate the chemical. As the pressure drops and the temperature rises, the solvent boils out of the resin, causing the material to loaf up. If it boils violently, there is too much residual butane in it.
Stop the process, take it out, and let it air dry or give it a hot bath to remove more butane. You don't want the slab loafing up more than a couple of inches. Increasing the air pressure reduces this loafing. Heat also plays a crucial role by lowering the viscosity of the patty, allowing the butane to escape. Keep an eye on the bubbles. You're looking for large, thin, self-popping bubbles. If the bubble walls are thick and not popping, the patty is too viscous and needs a higher temperature to loosen up and allow the butane to purge.
Conversely, if you are seeing no loaf expansion the heat may be too high. Some strains' finishing texture will be a tough sap that snaps if you pull it. For more info, see Buddering below. For a basic crumble. Flush fresh air through the system every half hour and oven-vac for four or five hours until the slab looks settled. Take the slab out and let it sit and settle for 20 or 30 minutes, but keep the oven on. Place your slab-covered parchment paper on a cool Thisfinished shatter will crack or pull and snap at surface, and pull the edge of room temperature, is bone-dry, and is see-through the parchment paper down with no impurities.
You want to see the shatter separate from the parchment paper. If it's stable, put on powderless silicone gloves, and flip the slab. Consolidate edge oil into the main body by folding it onto the top. Flip the patty every 12 hours, because pockets of butane get trapped between the bottom of the patty and the parchment paper.
Check to make sure the heat is transferring through the whole resin. Repeat this gentle heat-and-pressure-purging process three or four times over a couple of days. The low pressure and slight heat over a long period of time results in an amber-colored, transparent, crystalline, amorphous solid.
It should be brittle, or at least pull and snap at room temperature. You know you're done when you see very little slab activity in the vac oven, and it tests well below the 5, ppm threshold. Send a sample out to a lab to test it.
Buddering If the shatter turns from clear to opaque, a process called buddering has occurred. The process is a one-way street. Once a shatter budders it must go through a complex process to get it back to true shatter. Many strains including Blue Dream and Grand Daddy Purple are notorious for auto-buddering-that is, the waxes in the solution hydrate and nucleate, or clump up. OGs and Blue Dream tend to have a lot of wax in them.
Despite the most careful efforts to create shatter, the resin turns opaque during purging. At that point, it's best to make honeycomb.
Shatter turns to budder when heated too long, and even the finest shatter turns to budder eventually during storage. Buddering often starts in one corner of the resin patty, and spreads across the entire piece. If buddering has occurred, you can heat the resin to a honeycomb consistency, whip it into budder, or heat it down to oil. Mixing solvents slightly changes the mix's solubility; making it better suited to extracting specific terpenes in a particular strain.
Butane is a very simple organic molecule consisting of a chain of 4 carbon atoms with hydrogen atoms attached to them. Shortening or increasing the carbon chain yields propane 3 carbon atoms , and ethane 2 , and methane 1 , as well as pentane 5 and hexane 6.
One liter of n-butane can dissolve Pentane has zero water solubility.
More butane is removed when the temperature is raised and the pressure lowered, but it also removes more terpenes. More heat and low pressure cause the honeycomb to melt back down to an overpurged, condensed plant oil. Thick-gauge, 2"-wide, 25"-long Pyrex glass or stainless steel extraction tubes stainless steel is stronger; Pyrex is easier to see what's going on inside the tube. Open-ended extraction is far less efficient and hence, more expensive than closed-loop.
Since it doesn't reuse butane, it requires about 80 normal-sized canisters to extract from about five pounds of plant material versus the equivalent of 32 canisters in closed-loop.
If you cannot avoid cans of butane lighter fluid select a 5X or above quality fluid. There are many brands marketed for just this purpose. Stay away from Ronson and stove fuels-they contain poisonous additives. Set up your extractor in a well-ventilated area during a cool, dry day. Use very dry plant material. However, drying also sacrifices terpenes that are volatile at low temperatures. Tightly affix filters to the bottom of the tube using hose clamps.
Don't overtighten, as you can crack Pyrex. Add chopped trim and buds to the trim tube. Some people use small, untrimmed, pea-sized nugs. An overpacked glass tube can shatter under pressure, or cause the bottom filter to pop off, blowing cannabis into the BHO. Affix the canister discharge cap to the top of the tube. Alternatively, some open extraction tubes terminate in a hole that fits butane canisters, so you don't need a cap.
Set the tube up vertically with the filtered end at the bottom and the canister discharge cap end at the top. Place a large Pyrex dish underneath the tube. Position the fan so it blows fresh air at the extractor and worker, and pushes gas away from them. Discharge individual canisters into the hole in the egg-shaped top of the tube. Pressurized liquid butane will run through the material and eventually begin seeping through the filter and pooling in the Pyrex tray.
The tube will get cold during extraction and attract moisture from the air.
This dew can freeze and break a glass tube. Stainless steel is a better choice. It's stronger and will not break. The Pyrex tray of liquid Mean Skreenzjilters are made with chemical- and solution will also get very solvent-resistant material for use in the extraction of essential oils.
Take care to prevent dust or debris from blowing into the tray. See Winterizing below. If left outside in a well-ventilated area for a day to air purge, you'll be left with a waxy, yellow concentrate.
The BHO boils as the solvent quickly evaporates. Be careful. This is the most dangerous stage of open-ended blasting. The vast majority of liquid butane evaporates into the atmosphere and travels along the ground looking for a spark to explode.
Exercise maximum caution when double boiling. Also, you can use a breathable, water-resistant screen of some type over the Pyrex dish at this stage to keep dirt, dust, and debris from blowing into your solution from the fan. It takes between 15 minutes to an hour to purge most of the butane out of the BHO using a hot plate and double boiler. The end material should have the consistency of maple syrup, and will be ready for the vacuum oven. If you leave it on the hot plate for too long it will get drier, and you'll end up with a mixture of budder and shatter in the tray.
A hot plate is also warm enough to burn off terpenes. For a more thorough, professional purging, use a vacuum oven. See Closed-Loop Method above. Purging People use different combinations of temperature and pressure of the vacuum oven which affect the consistency.
Winterizing Winterizing liquid solutions removes the wax content so the material develops a shatter consistency.
Winterizing involves freezing the raw solution for 36 to 40 hours. The cold temperature causes the plant wax to precipitate and collect on the surface where it can be skimmed out. Winterizing shatter results in a much smoother smoke, because the heavy waxes are gone. Separated out, the wax can be used to make a candle. You can winterize an open-loop system with dry ice or a Buchner-a This Buchner for an open-ended glass beaker funnel fitted with a special extraction consists of a broad funnel 1.
For dry ice, place slabs of ice underneath the Pyrex dish used to catch the raw solution during extraction. The cold from the dry ice will cause the waxes and lipids to sink to the bottom of the Pyrex and congeal on it. Dump the remaining dewaxed solution into a clean Pyrex dish.
For a Buchner, the raw solution is poured into the Buchner funnel and a hand pump is used to pull the BHO through th. Some recapture units offer in-line winterization, which is a special stage in the process where the raw solution sits in a steel drum surrounded by a layer of dry ice. The dry ice chills the drum, and the waxes in the BHO collect on its sides.
Winterizing can be very dangerous. Do not simply stick a masonjar full of liquid butane solution in the freezer-you are making a bomb. The butane will evaporate out of the jar, flow down and out of the freezer until it finds a spark and explodes.
Some professionals collect the raw solution in a stainless steel pressure pot, add in more liquid butane, and place it in an explosion-proof freezer that is specially well-ventilated. We repeat: Placing butane in a freezer can result in a massive explosion.
It's super easy to decarboxylate purged BHO-just double boil it in a water bath set to above 'F 'C. Stir the BHO. When the bubbles suddenly start to taper off significantly, the BHO is mostly decarboxylated. So, when the bubble formation suddenly tapers off, the oil has reached the maximum head effect. Further heat makes it more sedative. BHO that is going to be smoked or vaped does not need to be decarboxylated.
The lighter or nail will take care of that instantly. Water is the enemy of solvent extraction.
Water is the most universal of solvents and it is very polar. It has spare electrons that interact with anything that is polar. Trichomes are nonpolar due to their waxy, oily covering. THCA is slightly polar, and bound up in the wax. Water in the butane extractor or plant material raises the polarity of the system, decreasing the solubility of the solvent and preventing butane from doing its job.
Keep water out of the extraction system, and run the process in a room with very low humidity. High heat is an enemy. Even low heat can make the delicate flavors and smells of cannabis disappear, and very high temperatures degrade THe.
Dissolved hash will also darken, leading to a far less desirable end result. Work in a cool, dry room, and do not overheat during purging. Terpenes begin to burn off at 68'F 20'C.
