Our decades of experience in designing and manufacturing the best and most cost effective processing systems for each of our clients’ applications have been applied during the past several years to provide the hemp industry with the best hemp processing systems. We design, manufacture and integrate hemp processing systems for biomass size reduction, extraction, ethanol (or isopropyl alcohol) falling film solvent recovery, decarboxylation, and multiple stage molecular distillation systems. The size of our systems are available from small industrial systems sized for cannabis production through the larger size systems necessary for industrial hemp scale processing of multiple tons per day of hemp biomass. These pages are dedicated to provide information regarding part of the technologies and systems which we provide.
We specialize in:
Hemp Size Reduction Systems
Ethanol Extraction Systems
Ethanol and Isopropanol Solvent Recovery Systems
Agitated Pot Still
Hemp Processing Principle Stages:
Hemp size reduction systems are based on taking the raw hemp biomass, drying to lower the moisture level to less than 2% and in controlled stages, reducing the biomass to the appropriate size for extraction.
Typical pretreatment production systems which we provide incorporate the following steps:
Receive raw hemp materials and then dry as appropriate with a belt dryer.
Load first hopper to feed rough grinding chipper.
Load second hopper to feed the cryo grinder. For the final size reduction step, the fine grinder is equipped with a Pulsed Jet Cloth Filter for dust collection.
If appropriate, the materials go to a pelleting machine for granulation.
Transfer the materials to storage and weighing.
Ethanol Extraction Systems are implemented in one of three basic designs: static, dynamic with either paddle or helical mixing, or centrifugal extraction. Systems to handle relatively small scale operations on through to multiple tons per day of biomass extraction are available to match the client operation. These systems typically include the alcohol metering tank, feed pump, extractor, discharge pump, storage tank for extract liquid, heat exchanger, connecting piping and valves, and controls. Operation temperature is dependent on client goals from ambient to -60 degrees C.
Solvent Recovery Systems are implemented to remove the ethanol (or isopropanol) from the extract. Mass balance of the feed to this processing step are typically only 5% or less extract or less requiring two process steps, the first, falling film evaporation, to remove the majority of the solvent from the extract in a single pass short residence time and the second stage to complete the drying of the extract to ready it for decarboxylation using a pot still which is slowly agitated. These systems are built to match the solvent evaporation rate necessary from the extraction system.
Decarboxylation Systems are built to take the dried extract oil from the solvent recovery system and hold at an elevated temperature long enough to decarboxylate the extract. These specially designed SS316L vessels are jacketed for the use of hot oil to heat the contents and have special anchor impellers with teflon tips to slowly agitated the extract and discharge completely after decarboxylation.
Distillation Systems are implemented in single, dual, triple or four stage systems and can be equipped with preflash stages at the extract entry to the first stage. Scale of systems are built to process 5, 10, 25, 100Kg/h and greater extract feed rates according to client requirements. The first stage wiped film evaporators are equipped with single stage vacuum systems while the molecular still stages have multiple vacuum system stages to attain the deep vacuum levels necessary to achieve the final purity levels necessary for crystallization.
Over a number of years and in concert with a variety of clients each with their own specific requirements, we have developed a variety of different processing technologies specific to the hemp industry. Our first goal is to determine with our client which of the many processes to apply to match their process goals and then to implement the appropriate solutions.
