Abstract The process of winterization consists of fractional crystallization of oils and fats followed by the separation of solids to make high quality salad oils.

Even between those three methods, variation of the extraction parameters has a strong influence the amount of plant fats picked up.

I am just curious if the waxes and lipids filtered out could be used for something else, such as a salve or lotion?

I have heard that before. You may want to rinse the filtered fats and waxes first. Maybe 20, 10, 5 micron for example. If you choose to go to the smallest micron immediately, your flow rates will suffer greatly as the larger waxes will clog the pores of the filter very quickly. Luke, Have you actually developed a working process with the exact equipment needed to winterize CBD? I thought it would be a great idea to winterize this that we have and produce enough pure, safe oil for vaping pens.

I could use the collaboration, thanks. For general questions about our equipment you can reach us at contactus brinstrument. Micheal, are you still available to help with winterization? We are in Eugene, Oregon and I need some crude winterized.

Has any body out there experienced this before? Surface area is king. The design is OK, but the size is not. The traditional porcelain funnels are much too small for any operation beyond the benchtop scale. Also consider that once the waxes begin to accumulate on the filter, filtration rates suffer dramatically.

In my opinion, most bad winterizations are caused by letting the solution warm up before it passed the filter. Added to this that they are slow, i.

If you want to make more than a couple liters a day of distillate, you will need an army of Buchners or just a larger surface area.

Could I just put the winterized oil in a bottle, and let it sit over a filter overnight? Or will the fats absorb back into the solution if it warms up too much? I make RSO for my sister with rhumatoid arthritis. How I do it is I chop up some weed to rice-grain fineness, put it in a cooking oil filter bag, decarb it at between degrees Celsius for 40 mins, then put it in the extractor, still in the bag.

Typically use cheese. What am I doing wrong? The fats will absolutely dissolve back into the ethanol. I cannot stress this enough, you must prevent the solution from warming as much as possible while you filter it. I have seen people do their filtration inside their freezer. You can also use a jacketed vessel. I also recommend covering with a lid in order to keep it cold, keep moisture out, and keep ethanol vapors out of your lab.

If the solution warms past a certain point you have essentially wasted your day regardless of how small a micron filter you use. Extracting with ethanol, especially warm ethanol, should be short. I recommend looking into QWET quick wash ethanol extraction. I have had very good luck with that process. Just remember to keep it covered as it cools, always use a glass dish for decarb and not longer than 20 minutes at degrees.

You are correct, I would rather suggest to decarb the extracts for 5 minutes at degrees to avoid formation of CBN. You will not decarb anything at degrees F. Should run it for an hour to allow max decarb. Please see this paper: Zaharia et al. Bull, Series B, V 82, No. The next step is a post-production process called winterizing, in order to remove lipids from cannabis oil, increases purity, improve oil color, and enhance […].

I know im about a year late on this topic, i have had very good luck winterizing using 2 very common technics used in various forms of alcohol manufacturing that have both given my clarity and a higher proof during the distillation process. Over the past year we tried some of the most expensive products our their and we reverted back to true…time and tested ingredients and machines.

My advice is search for past proven processes as we are working with an organic material just as in many different alcohol manufacturing. It is important to winterize to remove fats because the fats dilute the final concentration of cannabinoids in the final extract which lowers the purity and then affects the overall value.

These fats can cause the final extract to be cloudy and less attractive, also resulting in a lower value. Removing the fats and waxes will result in a pure sample, stable viscosity, and a longer shelf life. Depending on the method of extraction, it could vary the amount of fats that can be removed during the winterization process. A cold ethanol extraction is the best extraction method for minimizing fats in the extract. The CO2 extraction method is usually the method that contains the most amount of fats in the final crude extract.

The methods to complete winterization include four steps: dissolve, cool, filter, and boil. Now the extract is suspended in ethanol.

The waxes, lipids, and fats have now been dissolved in the solution. Solvent at warmer temperatures, completely dissolves the sample.

Cooling the solvent, the solubility is decreased, and the waxes are precipitated out. These fats have a lower solubility in cold ethanol compared to warm ethanol, which is why the next step is to freeze the solution. Waiting at least 24 hours should enough time for the waxes to precipitate out of the solution.
