Hemp oil / Medicinal Cannabis Oil, which is produced by mechanically pressing the hemp seeds, is not to be confused with either hemp essential oil (which is brought about through distilling hemp leaves and blossoms), or with hashish (cannabis) oil (which forms as a resin extract from the resin of the plant). Unlike hemp extract, hemp seeds contain hardly any THC (tetrahydrocannabinol), and thus cause no intoxication.

Careful harvesting and a mechanical pressing / oil pressing are indispensable for obtaining high quality hemp oil from the hemp seeds. The seed is protected by its tough shell from environmental factors such as oxygen and sunlight. In order to produce oil from the seeds, they must be pressed in an oil mill with the aid of a screw press/ oil press. Most suitable for this is the cold-pressing process/ oil press, since the oil temperature here (with hemp) should be between 40° C and 60° C, so that the hemp oil’s valuable contents are not damaged or reduced through the heat. With an oil content of 30-35%, hemp yields 180 to 350 liters of oil per hectare.

Characteristics and shelf life

The color varies according to the type of production. Cold-pressed hemp oil is greenish yellow, while warm-pressed oil is rather dark green; oil extracted with benzene and carbon disulphide has a brownish yellow tinge, and oil extracted with diethyl ether has an intense yellow color. Hemp oil smells herbal and fragrant, possessing a raw nutty aroma.

The taste varies from nutty to herbal.

The flash point is between 170 and 220° C; the melting point, from approximately -25 to -15°C.

In addition to containing diverse plant substances,such as chlorophyll, carotinoids and vitamins, hemp oil is composed largely of fatty acids (over 80% are unsaturated). Above all, the polyunsaturated fatty acids (omega-3) linoleic acid, α-linoleic acid, and the rare γ-linoleic acid contained in the oil are particularly important for a healthy diet.

Hemp oil stored in a dark bottle in a cool place will have a shelf life of six to nine months.

Pharmaceutical and medical uses

Due to its high percentage of mono-and polyunsaturated fatty acids, hemp oil is also readily used in the medical and pharmaceutical industries. It is successfully used, for example, to help treat high cholesterol, allergies, and arteriosclerosis, according to the Lexikon der pflanzlichen Fette und Öle (lexicon of plant fats and oils). Because it contains high amounts of important polyunsaturated fatty acids, especially α-linolenic acid and the rare γ-linolenic acid, it can also be used for dietary purposes, to deliver essential fatty acids to the body during a fat-restricted diet. In addition, it can be used therapeutically, to heal vascular disease for example, since the polyunsaturated fatty acids positively affect the cell membranes and thereby the elasticity of the vessels and the fluidity of the blood. Thus it strengthens the vascular system and prevents harmful plaque. What is more, it can also prevent the formation of blood clots (according to the Lexikon der pflanzlichen Fette und Öle).

Beyond this, the γ-linolenic acid contained in hemp oil, according to the Lexikon der plfanzlichen Fette und Öle, has an important significance in the formation of prostaglandin, an anti-inflammatory, and can also be effective against neurodermatitis, skin diseases, and psoriasis. It also aids in reducing diabetes, cardiovascular diseases and various chronic inflammations, as well as in reducing the risk of heart attack.

Further positive characteristics of hemp oil, according to Günter A. Ulmer’s book Heilende Öle (healing oils), are as an antispasmodic in epileptic attacks, multiple sclerosis, and chronic pain, thus also being able to positively affect the wellbeing of cancer and AIDS patients.

In the cosmetic industry

The high portion of unsaturated fatty acids, most especially linolenic acid and α-linolenic acid, lends it a strong lubricating property, making it very suitable for skin and hair, which is why it is readily used in cosmetic products. It is used particularly in products for rough, irritated or scaly skin, since the special fatty acids contained in the hemp oil stave off dehydration and tearing of the skin, as well as prevent excessive moisture loss. Moreover, this oil constitutes a very good softener for skin and hair, giving it wide application in the development of massage oil, ointments, creams, soaps, and also shampoos.

This oil is also employed in the natural cosmetic industry, since, owing to its pesticide-free cultivation, it contains no toxic residues.

Industrial uses

Hemp oil finds yet another field of application as technical oil in industry. Here it serves as a resource for the production of detergents, due to its high percentage of triacylglycerides. Through various chemical processes (saponification, ethoxylation, and sulfation), different resources such as soaps, emulsifiers, solvents, care nutrients, and surfactants can be produced for the cleaning industry, all having the advantage of being easily biodegradable. Furthermore, its gliding property allows it to serve in the production of printing ink, paints, and varnishes; and it is also employed in the manufacture of wood preservatives, lubricants, and wax crayons.

Particularly in the East it is still used today as lamp oil, because it burns especially brightly and, when combined with essential hemp oil, develops the aroma characteristic of hemp.

In the kitchen

Due to its fatty acid spectrum, which contains all the essential fatty acids important for human health, hemp oil ranks as one of the best and most nutritionally valuable plant oils and readily finds culinary usage. It is used chiefly to prepare salads, dressings, sauces, marinades, and spreads for bread. Its relatively low smoke point of 165° C, however, prevents it from being suitable for grilling or deep-frying, since the fatty acids would otherwise break down at higher temperatures and thereby alter the taste of the oil. In contrast, it is quite safe to use hemp oil for braising and steaming.

Screw press for cbd oil

March 28, 2019

Vincent continues to experience high demand for screw presses for solvent and oil recovery in hemp processing. Over the past twenty-four months we’ve seen a gradual shift from Lab Size equipment to Pilot Plant operations. We are now quoting industrial scale processing facilities with 200,000 pounds per day requirements for 2020. In addition to these larger projects, we continue to be a go-to solution for the smaller operators, with over forty screw presses, capable of 100 to 350 lbs/hr, ordered in the past six weeks.

A majority of our presses are used in the CBD and THC extraction process. Many types of extraction are currently being used: “hydrocarbon” (typically butane or propane), supercritical CO2, coconut or olive oil, ethanol (alcohol), and even hexane or heptane. Hydrocarbon and supercritical CO2 are primarily used for THC production as they give a much better terpene profile and associated flavor. Ethanol extraction, which only really entered the scene two years ago, has quickly become the mainstream, cost effective strategy for processors of all sizes.

When processing hemp for CBD oil, it is first dried and then soaked in ethanol. A typical mix would be 300 gallons per 1000 pounds of biomass. In the early days Vincent screw presses were used primarily for recovering additional solvent and oil following this initial wash. Free run solvent was either allowed to drain off, or was spun out in a centrifuge. In this application an additional 20% – 30% of solvent and oils is recovered. Our screw presses quickly pay for themselves with as much as 325 gallons being recovered from every 10,000 pounds of spent hemp. Ethanol represents the largest operating expense of a processor, especially when using 200 proof (because of the Federal Excise Tax.).

Press liquor expelled by the screw press goes through a winterization or de-fatting process. This removes suspended solids, waxes, lipids, and fines. We are aware of customers doing this at -80C to as high as ambient temperature.

Traditionally this has been a batch mode process. We are currently working with apparatus innovators who have brought continuous processing de-fatting equipment to market which can handle 3K, 5K and 15K liters per hour.

Diatomaceous earth or activated charcoal filtration can be used to remove chlorophyll and other impurities.

Finally, the liquor will go through an alcohol reclamation process to recover ethanol which is re-used upstream on fresh plant material. Typical equipment used for this purpose includes Rotovaps, falling film column evaporators as well as traditional ‘stills’. In general processors should anticipate a 92% recovery rate of ethanol through this processing. The technology around these operations is evolving quickly, with much theory borrowed from the flavor and fragrance industries.

At this point of the processing cycle, Vincent equipment has done its job and has given processors their valuable crude oil. This oil contains as much as 60% of the pure CBD Oil they are going after. Typically this crude will go through a short path fractional distillation or wiped thin-film evaporators.

At the other end of the process, on the farm, in 2018 Vincent spear-headed the use of alfalfa screw presses. These were used, at harvest, for removing excess water (juice) from fresh forage chopped hemp. The results have been significant, with the removal of up to 40% by weight as press liquor, with negligible CBD oil loss. Physical volume is reduced by up to 50%, with drying time being reduced by 2.5x. Over the past month we have received multiple orders for presses capable of running up to two acres per hour for this application. The drying process represents the biggest bottleneck and capital expense at harvest.

Vincent is proud to be participating in the introduction of efficient, high throughput, continuous processing capabilities to a maturing hemp industry.
