Closed-Loop Extraction Chillers for Pure Cannabis Concentrate Production

November 13th, 2019 by

At J.C. Younger (JCY), we have been manufacturing and remanufacturing industrial chillers for an array of applications, since 1956. We are also well-versed in oil extraction, and we are now known for the chillers we are manufacturing for the dewaxing process.

Oil Classification

As defined in The Free Dictionary, oil is “an unctuous, combustible substance that is liquid, or easily liquefiable, on warming, and is not miscible with water, but is soluble in ether.” Oils fall under the classifications of “animal, mineral, or vegetable.” How each behaves in the heating process, they further divide into the classifications of “volatile or fixed.”

While volatile oils are those “that evaporate readily,” are present in “aromatic plants,” and ” fixed (also known as fatty) oils, are not volatile. The fixed oils do “not evaporate on warming.” These oils have “a mixture of fatty acids and their esters.” While some refer to them as “solid, semisolid, and liquid, others refer to them as “drying, semidrying, and nondrying.”

Fixed (Fatty) Oils

An educational resource, from the University of California (UCR), will help you can further understand the different classifications of oils: drying, semidrying, and nondrying.

Drying oils, “absorb oxygen and on exposure dry into thin elastic films,” making them significant to “paint and varnish industries.” One of these oils is the “linseed oil” predominantly found in “paints, varnishes, linoleum, soft soap, and printer’s ink.”

Semidrying oils, “absorb oxygen slowly and only in small amounts.” While some of these oils “are edible, others are used as illuminants or in making soap and candles.” “Corn oil,” as so many of us known, is found in margarine, when “refined for human consumption.” And, in its crude form, corn oil “has industrial uses such as the manufacture of rubber substitutes, paints, and soaps.”

Nondrying oils, “remain liquid at room temperature and do not form a film,” and these types of oils “are edible and may be used in soap and lubricants.” We’re all very familiar with “olive oil.”

The Oil Extraction Process

Oil extraction methods go back to the time of the Egyptians, and “extraction of fatty oils varies,” as UCR reports. Extracted oils can “be further purified,” which makes them safer for human consumption and use. That is the removal of unwanted waxes.

Waxes

As the UCR resource explains, “waxes usually occur on the epidermis of leaves and fruits where they serve to prevent water loss through transpiration.” In the use of oils for commercial and medicinal purposes, it is necessary to remove these waxes. Temperature control is one of the critical processes in wax removal. A expert-constructed chiller is the solution to temperature control, from sub-zero temps and above.

Dewaxing with a “JCY” Closed-Loop Extraction Chiller for Pure Cannabis Concentrates

Some may believe that winterization and dewaxing are interchangeable process terms, but in the growing industry of cannabis concentrates, there is a difference, as found on PotGuide.com. “With a heightened importance placed on clean and pure concentrate production, many processors are now making sure to remove any undesired plant lipids and waxes from their final products.”

Winterization is a well-known process in the cannabis production process, but technology is now making dewaxing a favorable process. The dewaxing process offers “less steps involved, and the cannabis extract can be fully dewaxed all within the closed-loop system – removing the need to add additional steps such as winterization.”

The team at J.C. Younger is excited to offer the best “customizable chiller solutions to meet the needs of any cannabis operation.” We do believe the dewaxing process, using the “closed-loop extraction system, is the safest way,” to eliminate exposure to undesirable outside elements.

It is our mission to deliver the best in chiller solutions, and we’re here to make sure you get the best solution for your application, especially when it comes to removing waxes. Call us to find out more about everything we offer, along with the best chillers in the industry.
