Abstract
Spinning band fractionating column apparatus is disclosed having a spinning band formed with a magnet embedded in its bottom end in the manner of a magnetic stirring vane for rotation by a rotating external magnetic field at the bottom of the apparatus. Reflux is controlled by an angled drip edge on a rotatable condenser column that passes a portion of dripped condensate to a collecting spout with the portion varying as rotation of the condenser column brings the drip from said edge closer or further from center opposition with the spout.
Claims4
A bottom-driven spinning band fractionating system comprising:
- a. a still;
- b. a fractionating column mounted on top of said still;
- c. a reflux control chamber connected to the top of said fractionating column;
- d. a condensing column connected to the top of said reflux control chamber;
- e. a spinning band element mounted for rotation in said fractionating column, said spinning band element has a first end positioned in said still and a second end extending upward through said fractionating column terminating at said reflux control chamber short of said condensing column;
- and, a magnetic material mounted on said first end, whereby positioning said still on a magnetic stirring plate causes said spinning band element to rotate.
