The process of freeze-drying hemp and related extracts is more complex than freeze drying hemp plants. Many producers have attempted to use food freeze dryers for hemp and related extract, however, food style freeze-driers do not offer a method to control the freezing process, which leads to improper ice formation, inconsistent processing, extended drying times and degradation of the batch’s flavor, aroma, and color. Extracts are higher in concentration and require temperature-controlled shelves for freezing in place, and the advanced control systems for proper process control.
Here at Millrock Technology, we have been monitoring the hemp and related extracts industries and their projected futures. We’ve used our experience in the pharmaceutical freeze drying market to develop the right hemp freeze drying solution, equipped with fluid-filled temperature-controlled shelves and process instrumentation, resulting in:
Regulatory oversight from the US Food and Drug Administration is coming to the hemp and related markets. Hemp production will most likely be held to pharmaceutical level regulations, which means to meet those guidelines, producers will need to be able to control the freeze drying process and have the ability to replicate this process with each batch while providing the evidence that the product was processed properly. Our equipment is designed to meet the needs required by the FDA including 21CFRPart11 capable control systems.
