Abstract
The invention is methodology of producing a variety of cannabis derivatives such as THC, CBD, Delta-11, and budder. The technique involves the steps of: grinding a whole cannabis plant, including the root ball thereof, freezing the ground plant, soaking the frozen ground plant in a selected solvent, and, removing the solvent, thereby producing desired derivative of cannabis. Solvents include coconut oil, olive oil, vegetable oils, avocado oil, and seed oils.
Claims
1. A method of producing a refined delta-11 in cannabis consisting essentially of: a) grinding whole cannabis chosen for its delta-11 levels; b) freezing the ground cannabis; c) soaking the frozen ground cannabis in coconut oil; d) simultaneously applying pressure greater than 15 pounds per square inch and heating the frozen ground cannabis in the coconut oil in the range of 190-265 F. for a period of between 45 minutes and 3 hours, thereby yielding a delta-11 rich cannabis budder; and e) passing the delta-11 rich cannabis budder through a mesh screen having a size of 160-220 microns to remove cannabis parts thereby producing the refined delta 11 in cannabis.

(3) Root ball 10 is obtained and is repeatedly cleaned using water 11. This step is to remove any debris such as dirt and chaff from the root ball itself. The now cleaned root ball is placed in a grinder type of mechanism 13A and is ground into a powder. Additionally, a solvent 14, as describe above is added to the dry powder and a mixture is produced.
(4) This mixture 13B is poured through sieve 15 such as cheese cloth material to remove any suspended particles. The purified mixture is collected 16A.
(5) Depending on the process being employed, the purified mixture is subjected to heat 19B while in a container 17, thereby evaporating the solvent and desired cannabinoi which is condensed 18 and collected 19.
(6) Another process simply heats 19A. This produces a purified mixture 16A as the solvent evaporates 20A, leaving behind the cannabinoid. The resultant residue is then chilled to create an enhanced concentrate.
(7) In yet another refining process, the purified mixture is subjected to a centrifuge 21 to create an enhanced concentrate. After the process of applying centrifugal forces on the cannabinoid concentrate, the waste solvent is removed.
(8) In this manner, the cannabinoid obtained from the root is now useful for additives to provide the desired enhancement of the treatment being administered.
(9) This methodology illustrated in
(10) In one such tailoring the whole cannabis plant, including the root ball, is ground 13A and is then frozen (ideally using liquid nitrogen or carbon dioxide) to separate the sought-after derivative from the ground plant. When the solvent (and sometimes water) is removed (typically by evaporation), the residue has a high concentration of the derivative.
(11) To enhance the procedure, the plant being ground ideally already has enhanced characteristics, such as THC, CBD, or Delta-11.
(12) The solvent chosen for the process is ideally chosen from the group consisting of coconut oil, olive oil, vegetable oils, avocado oil, and seed oils. These solvents have been shown to produce exceptional results in the refining process.
(13) In the case of CBD, the solvent is from the group consisting of butane, hexane, ethanol, and butanol.
(14) In some application, where a budder is sought, pressure and heat is applied to assist in the separation process. In this context, pressure greater than 15 psi and heating (in the range of 190-265 degrees Fahrenheit) the frozen ground plant for a period between forty-five minutes and three hours. The budder so produced is a valuable derivative of cannabis.
(15) To assist in the process, and to enhance the solvent removal the soaked mixture 13B is passed through a mesh screen 15 to remove plant parts. In this context, the mesh screen has a screen size of 160-220 microns.
(16) When CBD is being obtained, the heat applied is less than one hundred twenty degrees Fahrenheit.
(17) It is clear that the present invention provides for an enhanced source for obtaining different cannabinoids so that patient treatment can be enhanced.
