VINEGAR, CIDER, AND FRUIT-WINES. 



The principal requisite of the correct working of the sparger is 

 that it revolves with ease around its vertical axis. This is effected 

 by placing in the centre of the vessel a glass pin drawn out to a 

 fine point and running in a small glass step ; the vertical glass 

 tube is guided in a sharp-edged wooden ring fastened to a stay 

 placed upon the cover of the generator (Fig. 16). The sparger 

 finds its centre of motion upon a lath inserted in the direction of 

 the diameter of the generator. This lath is placed at such a height 

 that the sparger can move freely between it and the cover of the 

 generator. The sparger being in position as shown in Fig. 16, a 

 funnel-form vessel, through which the alcoholic fluid is poured in, 

 is placed upon the glass tube.

^ By now pouring through this funnel-form vessel the alcoholic 

 liquid in a sufficiently strong stream, so that during its influx the 

 glass tube remains filled, it passes in fine jets through the lateral 

 openings, and, the sparger revolving in an opposite direction, is 

 distributed in the form of a fine spray over the filling in the gene- 

 rator. 



The use of the sparger overcomes the difficulties frequently 

 occurring with the disk, especially as regards the position of the 

 latter, and the circulation of air through the apparatus also takes
