By freeze drying kratom extract there is no heat used in the extraction process. Not using any heat the preservation of all the plant constituents is achieved. Also no moisture content so it is actually stronger per mg because your not weighing out water weight.
We use organic cane ethanol and distilled water with our premium kratom leaf powders to make extract. Once the ethanol and water have saturated the cells of the leaf it is drained off. The powder is then pressed by a 20 ton herbal press to get it bone dry.

The extract solution is ran through a rotovap to reclaim the ethanol. Once the ethanol is mostly removed the solution becomes a tar like resin extract. This is inserted in a pharmaceutical freeze dryer on stainless steel trays with wax paper.
The freeze drying process runs for 30 hrs. The temperature in the freeze dryer gets down to -40F and is pulled under a vacuum of 250 mtorr. When the process is complete all the moisture is remove while preserving all the plant constituents. The extract is bone dry and a grinder is not even needed to turn it into a fine powder.
Once the process is finished they are vacuum sealed with oxygen packs and placed in a sub zero freezer for storage and batch prep.
Our full spectrum resin is a true 20:1. This is the highest ratio one can get making resin. 20 kilos of powder make 1 kilo of resin. The kratom resin has all the water soluble and fat soluble plant constituents. This method of extraction you will not normally see because of the costs of equipment and time it takes to make.
By using a freeze dryer to finish our extracts we have a fresher and stronger finished product. Using a dehydrator or vacuum oven applies heat to dry out extracts to turn into powder. The heat causes damage and lowers the strength of plant extracts.
We have powders and solid kratom resin using this method. It is amazing how fresh and potent they are. We make small high quality batches.
