the one process. When this is possible, the 

 previous treatment with soda is avoided. This 

 is often the case with coco-nut oil if treated in 

 the Tropics immediately on its extraction from 

 the meat. 



To extract the oil the best known apparatus 

 one, too, that is perfectly safe and needing 

 no mechanical parts and no pump is the 

 Single Simplex Extractor, introduced twenty 

 years ago by M. Bataille, whose firm has in- 

 stalled this system in the works of the various 

 firms treating nut and seed oils in England, 

 France, Germany and elsewhere with the 

 utmost success. The Bataille solvent extrac- 

 tion apparatus is especially suitable for ship- 

 ment to the Tropics, as it consists of only two 

 vessels, as shown in the drawing on the pre- 

 ceding page, viz. : 



(1) The extractor with the necessary distil- 

 ling apparatus. 



(2) The condenser and solvent tank 

 (reservoir). 



In the upper portion of No. i is the ex- 

 tractor ; here the solvent passes through the 

 raw material and dissolves the oil. This solu- 

 tion then passes to the lower part, where the 

 solvent is parted by distillation from the oil, 

 the distilled solvent going back to the con- 

 denser No. 2. The oil remains in the lower 

 part of No. i and is then purified by steam 

 jets, taking away any trace of solvents, and, 

 at the same time, refining the oil. In the
