The column alembic is made in copper. The column alembic is also called alembic of continuous working process.
The column alembic is appropriate for the distillation of essential oils and plants. This is due to the fact that the water never touches at any time the product we want to distillate, which gives a great purity to the final product.
If we remove the column, the column alembic works as a traditional one.
The column alembic is made of four parts.
The cooking pot or boiler: It's the part of the alembic where we put the element we want to distillate.
Helmet: It's the upper part of the alembic from where the vapour travels down to the cooling condenser through the tube uniting them.
Column: It's the part of the alembic where we put the element we want to distillate.
The cooling condenser: The part of the alembic where the vapour is cooling and condensing and where the distillate comes up.
In this alembic you put the water in the lower part (cooking pot). You put the product you want to distillate in the upper column. When the water heats up, the vapour get to the upper part passing through a rack and heating up the element you want to distillate, and with the dragging of the vapour, essential oils and fragrances are extracted. In the cooling condenser, the substance is condensed.
Advantage of the column alembic.
The column alembic can work as a traditional one (perfect to distillate liquids) when the column is removed.
The column alembic is appropriate for the distillation of solid elements.
This alembic is the most appropriate to distillate fragrances and essential oils.
The column alembic is also called semi-industrial because you can save on the heating of water and you can distillate 2 or 3 times the capacity of the column, thanks to the fact that the column can be emptied and filled again without having to heat up the water again.
