This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,590.

Summary of the Inventive Concept

The present inventive concept discloses optimized systems and methods for producing high-quality hemp extracts and compositions, addressing the limitations of existing purification processes and methods of manufacture.

Background and Problem Solved

The original patent disclosed systems and methods for producing hemp extracts and compositions, but had limitations in terms of efficiency, yield, and purity. The present inventive concept addresses these limitations by introducing optimized solvent ratios, multi-step distillation processes, and advanced purification techniques to produce high-quality hemp extracts and compositions.

Detailed Description of the Inventive Concept

The inventive concept comprises optimized systems and methods for producing hemp extracts and compositions. Specifically, the system includes a solvent mixture of heptane and ethanol with an optimized ratio for efficient extraction of cannabinoids, and a temperature control module for maintaining a temperature range of between about -20°C and about 0°C during extraction. The method involves performing a multi-step distillation process with incremental temperature increases to optimize the separation of cannabinoids and terpenes, and collecting a final distillate with improved potency and stability. The composition includes a broad spectrum hemp extract with a CBD content of at least 80%, and at least one additional cannabinoid selected from a group of cannabinoids, wherein the sum of the additional cannabinoids is between 10% and 20%. The process involves using a combination of filtration and centrifugation to remove impurities and improve the clarity of the extract, and subsequently performing a crystallization step to further purify the extract. The system for manufacturing hemp-based products includes a modular design with interchangeable components for facilitating the production of different product formulations, and a quality control module for ensuring the consistency and purity of the final products.

Novelty and Inventive Step

The inventive concept's novelty lies in the optimized solvent ratios, multi-step distillation processes, and advanced purification techniques, which provide a significant improvement over the existing purification processes and methods of manufacture. The inventive step is the combination of these optimized components and processes to produce high-quality hemp extracts and compositions.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different solvent ratios, modifying the distillation process, or incorporating additional purification steps. Variations of the composition could include different cannabinoid ratios or the addition of other therapeutic compounds.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the hemp and cannabis industries, particularly in the production of high-quality hemp extracts and compositions for use in pharmaceuticals, nutraceuticals, and cosmetics. The target market includes companies involved in the manufacturing of hemp-based products, as well as researchers and developers seeking to improve the efficiency and quality of hemp extract production.
