Abstract
The invention regards an aroma extraction unit, comprising: —a hydration tank containing a mixture of plants or parts thereof and a liquid, said tank configured to contain a positive gas flow pressure, —a shearing unit configured for shearing the plants or parts thereof, —a hydrodynamic cavitation unit, and —at least one circulation unit, wherein the hydration tank, shearing unit, cavitation unit are in fluid communication, and the at least one circulation unit is configured for circulating the mixture from the tank into the shearing unit, further into the cavitation unit, and from the cavitation unit back into the tank and/or shearing unit.
Claims11
An aroma extraction unit for selective aroma extraction, comprising:
- a hydration tank suitable for containing a mixture of plants or parts thereof and a liquid, said tank configured to contain a positive gas flow pressure,
- a shearing unit configured for shearing the plants or parts thereof, comprising a rotor and a stator,
- a hydrodynamic cavitation unit, and
- at least one circulation unit,
- wherein the hydration tank, shearing unit, and cavitation unit are in fluid communication, and the at least one circulation unit is configured for circulating a mixture from the tank into the shearing unit, further into the cavitation unit, and from the cavitation unit back into the tank and/or shearing unit, thereby forming a circulation cycle, the extraction unit comprising a flow outlet after the cavitation unit configured for removing at least a part of the mixture from the circulation cycle, wherein the shearing unit is separate from the cavitation unit and configured for shearing at least 50 vol % of the plants or parts thereof into a characteristic particle diameter of between 1-100 μm.
