Medical Marijuana Infused Products – THC Oil Coating Systems

Ultrasonic Coating of THC Oil onto Marijuana Infused Snacks


medibles-3

Medical marijuana infused snacks are becoming popular on dispensaries’ shelves in increasing numbers, from medicated brownies and biscuits to medicated cookies, candy bars, granola, and even medicated dried meat snacks. They all provide a convenient alternative to the traditional marijuana vaporization experience, with the ability to control dosage per unit. These medible products can be made in commercial volumes using typical food industry processing equipment with the MMJ active (e.g. THC oil solution) added into the recipe. Another application for THC Oil is in THC transdermal cannabis patches, used primarily for medical marijuana use but more recently provided for recreational us as well.

Sono-Tek’s food grade ultrasonic spray coating systems enhance the quality and uniformity of medical marijuana medibles in a proven, validated manner, while using significantly less of the expensive THC oil. THC dosage can be precisely controlled, and is uniformly distributed across the surface of the snack. In the patented Sono-Tek design, THC oil solution is added in a separate step, following baking. Whether the final dosage is 1mg, 10mg or 100mg, the integrated flow control system guarantees a better than +/- 2% dosage repeatability and a typical +/- 10% deposition uniformity across the surface of the snack. In the case of THC oil coatings for transdermal cannabis patches, this repeatability becomes a very large benefit for manufacturers using Sono-Tek spray equipment to deposit THC, especially since the patch provides a more immediate and often stronger entry into the bloodstream. This makes a very accurate dosing highly desirable. In addition, ultrasonic coating allows the application of THC oil solution as an additive ingredient sprayed onto finished products such as prebaked or off the shelf items, enabling suppliers to provide these medically enhanced products without performing the baking operations themselves.

Ultrasonic Coating System Configurations: Sono-Tek spray systems are designed to be easily scaled up to higher production capacity from R&D, using the same core technology, making it easy to expand production with proven spray processes. Three typical configurations are (left to right):

  • Tabletop conveyorized R&D systems
  • Mobile coating unit pilot systems
  • Fully enclosed industrial scale systems

Ultrasonic nozzle systems’ gentle spray plumes enable close control of deposition quantities. THC oil solutions adhere without any dripping or overspray, and any added alcohol dilution solvents are quickly and efficiently evaporated during the coating process. Highly repeatable spray processes ensure dosage amounts remain consistent throughout coating of higher volumes.

Conventional THC Dosing Issue:The heat processing (baking) step of the manufacture negatively impacts some of the more volatile components of the medicated marijuana active, and makes it difficult to achieve controlled quality and potency.

Sono-Tek Ultrasonic Spray Advantage:THC oil solution is not exposed to degrading elevated temperatures, since it is added at a separate step, following the baking, providing higher effective concentration per dose in the finished product.

Benefits of Sono-Tek ultrasonic spray coating onto medibles include:

  • Enhanced quality product – no negative heat impact on the active solution
  • Validated dosage and uniformity across the product surface
  • Cost of goods savings from reduced usage of expensive active solution
  • Increased production line throughput with faster baking at higher temperatures
  • Faster time to market when spraying active onto already made snacks
  • Reduced maintenance and waste compared to conventional spray methods
  • Quick ROI followed by long term savings
