AUTOMATIC VINEGAR APPARATUS. 93 



The discharge-pipe of the automatic arrangement must enter a 

 space, in which are inserted eight pipes having the same diameter, 

 which conduct the alcoholic liquid to the separate generators. By 

 this arrangement all the generators receive simultaneously an 

 affusion of an equal quantity of fluid, which either sets the 

 sparger in motion or gradually trickles through the apertures in 

 the false bottom. The alcoholic liquid which has passed through 

 the generators collects either in the space under the lath-bottom 

 or runs directly through conduits to the collecting vessels. 



The conduits placed before the discharge apertures of the 

 generators are intended to conduct the alcoholic liquid to the 

 reservoirs, and there being no pressure of fluid in them they 

 might be merely of open gutters. For the sake of cleanliness and 

 to avoid losses by evaporation it is, however, advisable to use 

 glass tubes for the purpose. At the places where the discharge- 

 pipes of the generators are located, the connection of two glass 

 tubes is effected by a wooden joint with an aperture on top in 

 which is placed a glass funnel. For collecting vessels for the 

 alcoholic fluid running off from the generators of one group, vats 

 provided with lids are used. They have to be placed so low that 

 some fall can be given to the conduits, and in each of them is 

 a pipe provided with a spigot, which serves as a suction-pipe for the 

 pump intended to raise the alcoholic fluid. 



The manner of working in a factory thus arranged is as 

 follows :* The collecting vessel S x serves for the preparation of the 

 alcoholic liquid, which is then pumped into the reservoir Vj, 

 from whence it runs through the first group of generators, E I? to 

 the collecting vessel S n . From this it is pumped into Vn, and 

 runs through the second group of generators, E n , into the collect- 

 ing vessel S m . On being pumped up the third time it runs from 

 the reservoir V m through the third group of generators, E m , and 

 passes as finished vinegar either into a fourth collecting vessel or 

 is at once conducted into storing barrels. 



The distance the alcoholic liquid has to be raised from the 

 bottom of the collecting vessels to the reservoir amounting to not 



* To avoid repetition the collecting vessels are designated: Si, n, and m ; 

 the reservoirs Vi, u, and m ; the groups of generators EI, u, in.
