As the use of hemp and CBD oil for medicinal purposes continues to gain societal acceptance, the hemp drying and processing industry has grown rapidly. The passage of the 2018 Farm Bill legalized the growing of cannabis plants for industrial hemp, allowing for the cultivation and processing of the biomass material, as well as transportation across state lines for commercial and industrial use.
As scientists continue to research the properties and uses of CBD oil, it has been found already to treat a wide range of conditions, from seizures, anxiety, and depression to even helping with cancer treatment. As a result, there is a huge market for quality hemp and CBD products and a great opportunity for farmers to process dried hemp for medical and industrial use.
But because the industry is still growing, many operations lack the systems, processes, and equipment needed to produce a quality product for sale.
Drying is an essential part of processing hemp for CBD oil extraction, but the process can take a significant amount of time and effort. Hemp biomass often has a high moisture content, even up to 85%, which has to be reduced to an acceptable level in order to extract quality CBD oil.
If hemp is dried quickly and with minimal damage, then the process results in a higher quality product for market or processing. However, if hemp is dried too slowly or the moisture content is not suitably reduced, you may end up with a low-quality product or even a product that is unable to be sold or used.
After high-CBD hemp is harvested, it must be dried as soon as possible in order to avoid deterioration and to ensure preservation of the CBD content. As with any food or medicinal product, drying systems and facilities must be clean, dry, and without any insects or animals that could contaminate the product.
Hemp plants are typically hung upside down to dry by hand. The stems are then removed, and the plants are chopped into ½-inch pieces for further drying. Only once the product is thoroughly dry can the hemp be sent off for extraction of CBD oil. This process is not only time-consuming but requires a lot of manual labor and leaves little room for error.
After the hemp has been dried and processed, it can then be sent to a CBD processing facility to extract the CBD oil from the biomass material. Once the crude CBD-rich hemp oil is extracted, the CBD is further refined into a product that can then be sold or processed into CBD medicines, such as oils or capsules.
With the proper equipment, you can dry hemp correctly and efficiently, resulting in a product ready for CBD oil extraction or other industrial or medical purposes.
At Vulcan ® Drying Systems, we’ve developed a system to dry hemp more efficiently and thoroughly, reducing overhead costs and allowing growers to process their product faster. Our drying systems are custom designed to meet the unique needs of your climate and situation.
We have previously developed drying systems to reduce the moisture content of hemp from 80%-85% to 10%-12%. Our system can dry up to ten wet tons an hour, speeding up drying and reducing overhead by simplifying the process and helping you bring your product to market on a shorter timeline. Instead of drying just 50 pounds an hour by hand, our system allows you to develop a more efficient drying process, which in turn can help you obtain higher levels of CBD from the oil extraction process, resulting in a higher-quality product ready for market.
Our drying solutions are large industrial-sized systems capable of processing multiple tons of hemp biomass per day.
Whether you are just starting out in hemp processing or are an established grower looking to improve your process, we’re here to help.
Our custom-designed and manufactured drying systems can help ensure you produce and deliver a quality product for industrial or medicinal use.
CBD Friendly Dryers for Industrial Hemp
* Varying capacities and feed consistency will change product capacity.
The Vulcan® Drying Systems Hemp Drying System is custom-designed and manufactured to improve a customer’s individual drying needs. These drying systems consist of a correctly sized drum and a burner mounted in a concurrent configuration. Vulcan® Drying Systems Hemp Drying Systems are designed specifically to dry up to 10 tons per hour of hemp with an output moisture content between 10-12%.
Each Vulcan® Drying Systems Hemp Drying System is custom-built for each client. Systems include the following components:
- Feed chute or conveyor
- Rotary Dryer
- Combustion chamber with burner
- Secondary air blower
- Cyclone or Baghouse
- Induced air blower
Vulcan Sorting Systems Trommel Screens and Vulcan Sorting Systems Conveyors can be used for sorting and transporting Hemp.
Hemp Drying Process
Chopped hemp is fed into the rotary dryer by a feed conveyor. The dryer dries at low temperature by mounting a burner to a long combustion chamber to prevent direct contact with the burner flame. The burner flame is also cooled by a manifold of forced ambient air that passes through the combustion chamber as well. After passing through the dryer, the dried product is discharged to a transfer conveyor for further sorting, separation and processing. The vapor from the process is pulled through a large negative pressure chamber at the exit of the dryer to allow additional product drop out. Finally, the vapor is pulled through a cyclone or a baghouse to eliminate further airborne particulates.
System Process Flow
1. Feed Conveyor
The material is transported up a feed conveyor, prior to being dried in the rotary drum. Vulcan® Drying Systems offers state-of-the-art conveyors for each system manufactured in our facility.
2. Rotary Drum Dryer
The workhorse of the Vulcan® Drying Systems Hemp Dryer is the heavy-duty, low-temp, direct-heating rotary drum dryer. The low-temp dryer is extremely energy-efficient and can be configured to utilize a variety of fuels to perform the drying process. Our single-pass system is a simple, low-cost method of producing a marketable product from biomass material. Low temperature is maintained by mounting a burner to a long refractory-lined chamber. Auxiliary air is added in the chamber to keep the temperature levels low.
3. Material Discharge
On discharge, all processed material is sent to the client mandated location for re-purposing and re-sale. However, the Vulcan® Drying Systems Hemp Dryer doesn’t stop there. This system ensures that all particulate matter is removed in a safe and secure fashion.
Processing chopped hemp is not without its dust. Fortunately, the included Vulcan® Drying Systems Cyclone removes particulate.

Hemp is created through the agricultural process of growing and harvesting hemp plants. Hemp is an organic product and causes no harm to the environment or public health. However, there can be some negative impacts on the surrounding environment if pesticides or excessive water are used during the growing season.
Regulations on hemp production vary by state. All producers should check with their state prior to growing or processing hemp. The growth of hemp for marijuana is only legal in some states, while the growth of hemp for CBD oil and other products is strictly regulated at the state and federal level. See more about the USDA regulations on hemp production here.
Hemp is in high demand and can be used in a variety of products, but is especially popular for natural medical products for the treatment of anxiety, depression, seizures and even assistance with the negative effects of cancer treatments. Hemp with high CBD content has a variety of industrial and commercial issues that make it a valuable product.
A wide variety of marketable products can be made from hemp and CBD oil, including paper, rope, textiles, biodegradable plastics, health food, natural treatments and even some construction materials and fuel.
Thorough and fast drying of hemp results in a higher quality product for processing or market. Our drying systems allow growers to dry hemp much faster, resulting in a product ready for CBD oil extraction or other industrial or medical purposes.
About the Hemp Industry
Since hemp was legalized in the 2018 Farm Bill, interest in growing industrial hemp for CBD production has skyrocketed. When properly dried and processed, CBD oil can be extracted from the hemp plant for use in a variety of products. While most people associate hemp only with medicinal uses, the material can also be used in textiles, paper, construction, and even fuel.
The U.S. Hemp industry produced approximately $820 million in revenue in 2017 and is expected to grow at least 14% by 2022, while the global hemp market is expected to reach over $10 million by 2025. This rapidly growing market offers a promising option for farmers looking for a product with constantly expanding potential.
