Definitions
- the invention relates to a device and a method for extracting one or more components, in particular cannabinoids such as tetrahydrocannabinol (THC), from a mixture of substances.
- cannabinoids such as tetrahydrocannabinol (THC)
- plant material is placed in a chamber or bladder of the device.
- Steam is then introduced into the bladder, preferably at a temperature of 180°C, which dissolves the essential oil from the plant material.
- Such steam distillation processes are usually operated in batch operation. The process is completed when the temperature of the plant material in the bladder has warmed to the temperature of the water vapor, since no condensation of the water vapor can then take place on the plant material.
- a particular disadvantage is that the method depends on the loading of the chamber, since the plant material can be flowed to or overflowed by water vapor to varying degrees depending on the loading height and density, possibly also depending on the chamber dimensions. Plant material located further out is generally provided with significantly better flow, while plant material located further out can be covered by layers of plant material located further out. This means that both the duration of the process and the amount of essential oil extracted can vary greatly. Likewise, an average residence time of the plant material in the bladder or chamber is difficult to set.
- THC tetrahydrocannabinol
- the THC content can vary greatly from cannabis plant strain to cannabis plant strain. A THC content of more than 30% is possible in certain cannabis strains under optimal conditions. Depending on the strain, medical cannabis currently offers THC levels between less than 1 and up to 22%. The THC content of official medical cannabis is between less than 0.05 and 10.2%.
- THC extract from the cannabis plant provision can be made to determine the THC qualitatively and/or quantitatively during the growth of the hemp plant in order to be able to precisely determine the harvest time.
- Sensors can be used for this purpose, in particular at least one infrared sensor.
