Frost Bags and Dry Ice Extraction

Frost Bags and Dry Ice Extraction

Frost BagsCold Water Extraction has long been considered the most popular and reliable method for extracting valuable plant resin and essential oils from harvested plant material. It has always been chosen as the fast and easy way for resin extraction because it requires only a bucket, some filtration bags, some ice water and something to stir. Growers can use as many bags as desired for multiple levels of extract quality. For those of you who have never tried it, it as easy as stirring your residual plant material in icy cold water. As the trichomes fall off the leaves and buds, they are captured by the fine mesh nets on the bottom of the bags. Each bag allows for different size microns of filtration; different levels of quality.

Dry Ice Extraction and Frost Bags are taking over as the new preferred method of Trichome ExtractionFrost Bag Dry Ice Extraction

Despite the popularity, ease of use and reliability, Cold Water Extraction may soon be extinct. This is because there is a new method of resin extraction that is rapidly gaining in popularity across North America. This new method is cleaner, faster and more effective. This method promises less waste, less work, and easier clean-ups. This method is known as Dry Ice Extraction and the new Frost Bags from Canada are the best way to get it done! Dry ice is solidified carbon dioxide (CO2 – the same things plants love) and is not classified as toxic or harmful in accordance with G. H. S. of Classification and Labeling of Chemical Standards. The Frost Bags Dry ice extraction process eliminates the use of water extraction, which is a major source of contaminants during the process of extracting essential oils. It’s a super cold substance that “evaporates” (sublimates) away into the air as it transforms from a solid to a gas. The fact that it’s super cold and converts directly to gas are the clear advantages in the extraction process. Frost Bags will give you a far superior product in a fraction of the time!

No More Water How does Dry Ice Extraction Work?

In its most basic practice, Dry Ice Extraction can easily be performed by using one 5 gallon bucket, one bubble bag (between 220 and 120 microns) or xtractor bag and a ¼ block of dry ice. The idea is to let the plant material and dry ice sits together inside the bucket for a few minutes, and then pour the contents into the bag. Then hold the top end closed and shake the bag while moving across a glass table for about 3 minutes. In the end, your table will be covered in golden trichomes.

How does Dry Ice Extraction with Frost Bags work?No More Mess

The Frost Bags method works pretty much the same way except you don’t need a table and the bucket remains right-side up until you are ready to pour out the trichs. You have your choice of two sizes: 5 gallon kit or 20 gallon kit. Each kit includes a Black Frost bag of 220 microns, a Blue Frost bag of 160 microns and a sleeve for the bucket. For you pros, a 60x microscope is included. You would need to supply your own bucket, gloves, and dry ice. The formula calls for combining the plant material with the dry ice inside the bag and letting it sit for a few minutes (Mesh side up). After a minute of gentle shaking, turn the bag over into the bucket, place the sleeve over the top-side of the bucket and firmly hold the bucket handle and bag handle together. The final step calls for a vigorous, but not exaggerated, 3 minutes of shaking the bag inside the bucket. When the sleeve comes off and the bag is removed, the bottom of the bucket should be full of resin.

Results The results speak for themselves. Most growers will never go back to cold water extraction or even tumblers after working with dry ice. If you haven’t used Frost Bags yet, you’re not doing it right!

Cold Water Extraction of Essential Oils with XXXtractor Bags and XXXtractor Wash Bags

XXXTractor 5 Gallon 3 BagsSo, you’ve managed to grow and harvest the most magnificent lavender plants on the planet. The fragrance is there for the taking, but how do you start? How do you most effectively extract those precious essential oils? Ruling out chemicals and other contaminants, your best bet is cold water extraction. With this simple process all you need is a set of high-quality extractor bags, a bucket, some ice water and something you can use to stir.

Choose XXXtractor Bag Quality for your Herbal Extracts

The only real decisions to be made before starting are: selection of extraction bags and the number of bags (or grades) you intend to use. We like to work with XXXtractor bags because they are fully assembled in Canada. Also, they use the toughest 100% waterproof nylon fabric available for the side walls, with a specially engineered, industrial-grade, Swiss polyester yarn mesh for precise, reliable and durable filtration.

The basic set includes three bags with escalating grades of filtration: 25 microns, 75 microns, and 220 microns. For those who prefer more grades of filtration, there is a 5 bag set that includes 100 and 150 microns. These extra extractor bags allow you to separate your herbal essences into 5 different grades of purity. Also, if you grow a variety of plants with different crystal sizes, additional filtration levels allow you to capture the optimal extract from your entire garden. (Depending on the amount of plant material you are working with, XXXtractor bags are available in 1 gallon, 5 gallon, 14 gallon and 55 gallon sizes.)

Step-by-step Cold Water Extraction Process

The process is simple:

  1. Insert one bag into another with the finest filtration level on the bottom (25 microns) working up to the highest (220 microns) and line the bucket with the entire set of extractor bags
  2. Add cold water to the bucket until it is half-way full
  3. Add the plant material to the water and spread it around evenly
  4. Add enough ice to cover all the plant material
  5. Stir vigorously for approximately 20 minutes – feel free to cheat with a hand mixer
  6. Carefully remove each extractor bag individually and let the water drain completely over the bucket, before setting aside.

For those who are veterans in the world of cold water extraction and prefer to enlist the help of a washing machine before adding plant material to the extractor bags; XXXtractor offers two sizes of mesh Wash Bags to be used with small washing machines such as the bubble machine or regular size machines. Cool demonstration videos are available online such as the one below.
