Case Studies

Drying Hemp for CBD Extraction

Challenge:

When harvesting hemp destined for CBD extraction you have limited drying options.  Once hemp is harvested you have less than 1 hour to begin drying before decomposition, mold and mildew begin.  

Current drying options include:

  • Leaving it in the field to dry naturally, hoping the fall rain doesn't spoil it
  • Buying expensive "hot boxes/containers" which are very labor intensive, take up lots of space and are limited in capactiy
  • Traditional grain dryers which damage the CBD molecule with heat

Solution:

IEC Thermo HEMP dryers combine established drying and processing techniques into an attrition flash drying process that keeps cannabinoid molecules intact and undamaged, providing a timely and cost-effective means of stabilizing your valuable harvest before mold, mildew or composting can occur, allowing for future processing at a pace you determine.

Post-Ethanol Extraction Alcohol Recovery

Challenge:

For those employing ethanol extraction, after extraction you will need to remediate your post extraction biomass.  

After the soaking period the alcohol-hemp "slurry" is run through a screw press or centrifuge to separate the alcohol and the hemp biomass.  Even with the best screw press or centrifuge the extracted biomass will still hold approximately 30% alcohol by weight.  This is not only a fire hazard, but alcohol that could be recovered and hemp biomass that has several potential uses.

Solution:

IEC developed the ARTS Dryer, Alcohol Recovery Technology System dryer to safely recover 100% of the ethanol to reuse in extraction and leave you with 100% dry hemp biomass which can be used for livestock feed, to field fertilizer, to being pelletized for fuel.

Using our 1000 pounds per hour system 40 hours a week will recover 300 lbs/hr * 40 hrs/wk = 12,000 lbs or 1,440 gallons.  At $25/gallon this is $36,000 a week in recovered alcohol.  and 100% dry hemp.

Animal By-Product Processing

Challenge:

A large multinational poultry by-product processing plant had run out of room to handle their customer’s changing processing requirements.

Solution:

IEC collaborated with this client to solve what at first seemed to be a simple problem, but in reality was quite significant. A key processing area had little or no room for a new piece of equipment. IEC modified a screening system in the flow sheet so that it cooled as it screened. This modification saved the customer significant capital cost and downtime.

Mineral Processing

Challenge:

A major Livestock grain and feed supplier was looking for a mineral treatment to reduce spoilage of local and imported grains.

Solution:

IEC co-developed a mineral treatment that far surpasses the performance of other available products.
