Decortication

Industrial Hemp Fiber and Hurd processing.

United Precision Engineering, LLC is the parent company of HPP, giving us access to a wealth of engineering and design resources.  The latest mechanical engineering 3D design software is used to create an equipment layout specific to your building and the hemp materials you produce.

Hemp Processing Partners was built to connect Producers to the technology and techniques they need to be profitable in the Hemp Industry. Through research and development HPP has become the industry leader in Large Scale Hemp Separation and Decortication technologies.  At HPP we design and engineer turnkey systems as well as custom systems solutions of all scales.

As a family-owned company, we are committed to achieving long lasting technological progress in the best interests of our customers while evolving and growing with the Hemp industry for many years to come!

System Control

  • The entire system is controlled by a touchscreen and PLC system which can be set up to run from a tablet or iPad with remote programming, diagnostics and troubleshooting. 
  • The control system can be integrated with an RFID inventory tracking system.

Incoming Hemp

  • Hemp is brought into the facility in bales or loose, depending on the harvest method and end products to be created.
  • Baled hemp is processed through a bale breaker and fed into a trommel or threshing machine to remove flower and seed from the stalks.
  • Stalks are carried by a belt conveyor to the vertical mill for decortication.

Flower and Seed Processing

  • The flower and seed fractions are elevated from a surge bin by a drag conveyor to feed a drum screener.
  • Material that is screened off, consisting of loose flower material and seeds, will then pass through a Kice Multi‐Aspirator to separate hemp from seeds. Seeds will fall through the multi‐aspirator to be collected and clean hemp will be lifted by a Kice air system to a cyclone receiver.
  • Larger material (i.e., buds, sticks, stems) that passes across the Drum Screeners will be fed by gravity directly into a Bud Buster. The Bud Buster strips any remaining buds from the stalks as well as break up any larger buds. Hemp will be broken up, seeds will be liberated, and sticks/stems will be largely undisturbed. The broken‐up hemp material will discharge through a set of screens and be lifted by the same air system to the same cyclone receiver that is handling aspirator liftings. Sticks and stems will discharge from the Bud Buster for collection. An optional secondary screener and conveyor may be placed after the Bud Buster to recover any seed liberated from the buds.

  • This material may be fed to a pelletizer for densification
  • Seed from the aspirator will be fed to a seed cleaner for final cleaning in preparation for uses such as planting, cold pressing, or hulling.
  • The system can include a cold press for hemp seed oil and a dehuller to make hemp hearts for food products.
  • The material discharging from the cyclone receiver will be clean, high value hemp with sticks, stems, and seeds removed.

Stalk and Stem Processing

  • The vertical mill decorticates the material to liberate the bast fiber from the inner hurd.
  •  The material is blown from the mill outlet via air to a settling box/horizontal aspiration chamber to remove it from the airstream and roughly separate the hurd from the fiber.
  • The material is then screened to classify it by size and further separate the fiber and hurd.
  •  The hurd sizing screens are tailored the desired uses of the product. o i.e., large pieces for animal bedding.
  • A compression bagging station can be installed for standard bedding packaging.
  • Small to medium particles for Hempcrete.
  • Fine particles for bioplastics.
  • The larger hurd can be size reduced through a hammermill or micronizer to make it suitable for bioplastics.
  • The fiber length can be tailored to the end product desired through adjustments to the vertical mill.
  • Further fiber processing steps such as cottonizing can be done after the fiber is separated from the hurd.
  • The material is then conveyed to bagging stations, bulk bins, live bottom trucks or directly to subsequent manufacturing operations in the facility.

The Vertical Mill

  • The Vertical Mill comes from the automotive recycling industry handling extremely aggressive and abrasive materials such as stainless steel, copper and other metallics. So, the robust nature of the machine and patented inner core provides the processing power to handle such a strong fibrous material. While still allowing for fiber retention.
  • Serves several Industries with little to no changes on the equipment. Such as; Automotive recycling, Plastic recycling.
  • MRF’s, Tires, Shingles, Copper, Chopping, Pulp n Paper Etc.
  • ECE’s patented Vertical Mill represents a major advance in high throughput single pass decortication technology. Coupled with the right bale feeding and material cleaning equipment, an ECE liberating mill can process up to 6 tons per hour with a higher degree of hemp fiber and hurd refinement than any technology on the market.
  • Any form of stalk from the Hemp or CBD industry
  • Retted or on Unretted
  • End products can go straight to market or further refined for other Industries
