Small parts often make a big difference in a distillation plant. In this photo, look at the left side: a slim stainless steel bag filter and a blue transfer pump stand next to the stills. Together, they keep the hydrosol clean and move it where it needs to go.
What you see in the photo
Two stainless steel stills sit on a steel platform. In front of them, tall condenser columns lead to the conical Florentine separators. Then, on the left, the bag filter and the pump connect to the hydrosol line. Also, ball valves let the operator open or close each route.
What does a bag filter do?
A bag filter holds a fine fabric bag inside a closed housing. The liquid flows through the bag, and the bag catches plant particles and dust. As a result, the hydrosol leaves clear and ready for storage or bottling.
You can read more about the general idea on the filtration page.
Why a bag filter in a distillation plant?
- Clear hydrosol: buyers expect a clean product without particles.
- Protected pumps: the filter stops solids before they reach the pump.
- Easy service: the operator opens the lid and swaps the bag in minutes.
The role of the pump
The transfer pump moves the filtered hydrosol to storage tanks, to a cohobation unit or back to the still. Therefore, nobody needs to carry heavy buckets. In addition, closed lines keep the product clean.
In short, a bag filter and a pump turn a basic still into a tidy, efficient plant. See complete plants on our essential oil distillation units page.
Also, the same pump can send rose water to a cohobation unit, so you recover the oil it still holds.
FAQ
How often do I change the bag? That depends on your plant material. Many producers check it after every few batches.
Can I add a filter to my current plant? Yes. It fits into the existing hydrosol line.
