A revolutionary German-built technology that strips cannabis flowers quicker than current technology will be on display at the Southern Hemp Expo in North Carolina.
A new machine will be on display at this year’s Southern Hemp Expo in Raleigh, North Carolina, taking place 2 September to 4 September, that can strip cannabis flowers up to 12 times faster than current machinery.
The company, HHH Hemp Harvesting Technology, Burgdorf, Germany, has said that cost analysis of fieldwork in Germany, Switzerland and Luxembourg showed the HHH 700 model can reduce labour costs by 73%, and brought down the number of staff from 15 to only four workers required to run the harvester in “semi-stationary” operation.
Improving cannabis harvesting
The machine works by workers collecting and then hand feeding bushy cannabis stalks into the harvester’s stripper mechanism as a tractor moves the unit from one spot to the next in the field, and can also operate whilst stationary in farm buildings for indoor and greenhouse growers. It can also collect flowers from conventionally planted, straight-stem industrial hemp varieties while running through the field continuously.
Developer Heinrich Wieker, who worked with manufacturing partner, a German specialised machine maker, Eilhauer, to develop the machine, said that with industrial hemp the machine was up to 20 times faster than hand harvesting.
“With the bushy plants, it’s 12 times faster” than picking the plants by hand, Wieker added, who estimates the HHH reduces the time required for harvesting one bushy cannabis plant from three to five minutes to roughly 30 to 50 seconds.
Using a patented stripping mechanism, the machine detaches cannabis flowers from the stalk and stems, and the flowers can be collected in a bag or container.
In field operation mode for harvesting traditional hemp plants, the hemp stalks are left in the field for retting, and, depending on plant maturity at the time of harvesting, the machine can also shake out the seeds.
European cannabis market
Wieker said that, the company is ready for US market after starting manufacturing and construction of the HHH-700, with a focus on the European market in the first year, and is now addressing demand that has developed in the US in 2021.
Designed to be efficient for conventionally planted hemp and marijuana grows as small as five hectares, the standard single-unit HHH can harvest up to two hectares per day in industrial hemp and 0.5 to one hectares in bushy crops.
Wieker said: “Existing flower harvesters weigh 18 tonnes, cost more than €600,000, consume enormous amounts of fuel and are difficult to transport over longer distances.”
The machine has been in development and production for four years and has an aluminum frame and rollers for weight reduction, as well as stainless steel components such as chains and other flower-contacting parts for pharmacy- and food-grade yields.
Biologists identify “hacks” cannabis uses to make cannabinoids
The research provides insight into how trichomes create high quantities of cannabinoids without the plant poisoning itself.
Previously, it was unknown how cannabis naturally creates high quantities of cannabinoids and terpenes. Now, new research from biologists at the University of British Colombia has defined the “high efficiency” hacks that the plant’s cells use to do this.
A number of biotechnology companies are now using yeast or cell cultures to create synthetic cannabinoids. The process allows for the mass production of cannabinoids to create a high volume of products in order to keep up with consumer demand.
In a new study, published in the journal Current Biology, plant biologists uncovered the microenvironments in which THC is produced and transported in cannabis trichomes, shedding light on several critical points in the pathway of making THC or CBD within the cell.
University of British Columbia botanist who led the research, Dr Sam Livingston, commented” “This really helps us understand how the cells in cannabis trichomes can pump out massive quantities of tetrahydrocannabinol (THC) and terpenes—compounds that are toxic to the plant cells at high quantities – without poisoning itself.
“This new model can inform synthetic biology approaches for cannabinoid production in yeast, which is used routinely in biotechnology.
“Without these ‘tricks’ they’ll never get efficient production.”
Livingston, along with co-author Dr Lacey Samuels, used rapid freezing of cannabis glandular trichomes to immobilise the plant’s cellular structures and the metabolites in situ.
This enabled them to investigate cannabis glandular trichomes using electron microscopes that revealed cell structure at the nano level, showing that the metabolically active cells in cannabis form a “supercell” that acts as a tiny metabolic biofactory.
Until now, synthetic biology approaches have focused on optimising the enzymes responsible for making THC and CBD – like building a factory with the most efficient machinery to make as much product as possible. However, these approaches haven’t developed an efficient way to move intermediate substances from one enzyme to another, or from inside the cell to the outside of the cell where final products can be collected.
This research helps to define the subcellular “shipping routes” that cannabis uses to create an efficient pipeline from raw materials to end products without accumulating toxins or waste products.
Dr Samuels stated: “For more than 40 years, everything that we thought about cannabis cells was inaccurate because it was based on dated electron microscopy.”
“This work defines how cannabis cells make their product. It’s a paradigm shift after many years, producing a new view of cannabinoid production. This work has been challenging, partly the result of legal prohibition and also due to the fact that no protocol for the genetic transformation of cannabis has been published.”
New partnership to commercialise synthetic THCV and rare cannabinoids
Open Book Extracts has partnered with developers of a proprietary chemical synthesis platform that produces ultra-pure, high quality, sustainable cannabinoids, Nalu Bio.
Open Book Extracts (OBX) has entered into a research, development and commercialisation partnership with Nalu Bio.
The partnership will allow Nalu Bio to advance its THCV production method from research and development to commercial-scale manufacturing using its proprietary and scalable synthesis platform.
With a 76,000 sf. NSF- and ISO 9001-certified research and production facility near Durham, North Carolina, OBX and Nalu Bio plan to begin initial production of THCV in September 2022 with market-ready compounds available before the end of the year.
CTO of Nalu Bio, Matthew Roberts, commented: “Our THCV is produced in highly scalable reactors at factory-scale, using low-cost, safe and effective starting materials. Nalu Bio and OBX are both innovators in their respective fields, and this partnership is mutually beneficial for two industry leaders.
“Nalu Bio prides itself on partnering excellence, and we’re excited to deliver high-quality, safe, and low-cost cannabinoid ingredients and products to the market.”
Nalu Bio’s vision for the synthesis and cost-effective mass production of cannabinoids mimics the history of aspirin – the therapeutic value of aspirin for pain relief was discovered, and while initially derived from willow bark, it is now mass produced at factory-scale with higher quality and dosage consistency, which has benefited billions of consumers worldwide as it has become the most commonly used drug in the world.
THCV will be the first cannabinoid available at commercial scale through this partnership, allowing OBX and Nalu Bio to offer the highest quality, most consistent dosage of THCV.
Both OBX and Nalu Bio envision a range of additional cannabinoids to be released through this partnership,including a broad range of cannabinoids from hemp and natural sources, such as CBD, CBN, CBC, CBG, CBT, CBDa, CBGa, CBDV, and THCV.
OBX CEO, Dave Neundorfer, commented: “I am excited about the value Nalu Bio and OBX will bring to the cannabinoid therapeutics market. This partnership is well-positioned to meet the needs of the growing synthetic cannabinoid market and deliver potentially life-changing products to consumers worldwide.”
Greece welcomes first medical cannabis plants from Israel
Mother plants have arrived in Greece, marking the beginning of production for Tikun Europe.
Tikun Europe has welcomed the first mother plants from Israel and will now begin cultivation in the company’s facility at Korinthos, Greece.
Transportation of the plants was carried out by Skyserv Ground Handling Services. The shipment of the plants was made in specially designed containers under controlled environment ensuring the best possible conditions throughout the transportation from Israel to their final destination.
Cultivation will take place in Tikun Europe’s vertically integrated greenhouse unit, with an area of 21,000 m 2 and it anticipates an annual production capacity of 10 tonnes of dry flower.
