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 8 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 the feed conveyor, prior to being dried in the rotary drum. Vulcan® Drying Systems utilizes 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 shredded hemp is not without its dust. Fortunately, the included Vulcan® Drying Systems Cyclone removes particulate.

Benefits of the Vulcan® Drying Systems Hemp Drying System
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. 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.

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.
