A new essential oil distiller has been developed, with good accuracy, exactness and practicity on loading and unloading, to be used at industrial and research labs.
The device uses electricity to operate, but it can also be adapted to a gas burner for field operations. On this project, we have been seeking for solutions to problems on glass devices.
Comparative advantages over the traditional distillers:
Except for the viewer, made of impact-proof glass, the whole device is made of stainless steel 304, with 316 stainless steel on all joints and connections that come in contact with the oil, including the vapor generating electric resistance controlled electronically. These materials grant the destiller great resistance and durability, and low containment rates on the oil.
The inclined condenser of monotubular type has been projected to eliminate all laminar flows, and assembled with a high thermal conductor stainless steel. Those characteristics allow the operation of the equipment with up to 10L/h of cooling water. The low water consumption provides not only economy, but the possibility of using a little raised reservoir for water supply on field experiences, when gas operated.
The vat removable bottom cover can be replaced with an accessory that can extract liquid or semi-liquid materials. Table 1 (at the bottom of the page) compares extractions from the same vegetable materials using the Mini Distiller and a traditional Clevenger apparatus. The greater efficience is due to a better generation, and a higher vapor contact with the tissue, allowed by the architecture of the device.
The material to be destilled is placed on a 2,6L vat, assembled with a perforateed removable bottom cover to ease the unload. The vat is removed completely from the device body, allowing faster operation and two-vat usage, in a way to continue destilling in a vat, while loading the other one.
While distilling, the vat is placed over a special flange on the superior part of the device body, closed with a scape-free cramp that holds all of the vapor inside while directing it to the condenser.
The condensed passes through a glass siphon, where the essential oil is separated. The decanted water returns to the device body, closing the cicle. The extracted oil is quantified by level-reading, It can be removed either by the 3-way sphere valve, or by suction from the relief valve.
When electrically operated a safety system controls the electric resistance to the adequate water level, automatically replacing operational or accidental vapor scape.
