The hopper is placed in such a position as to prevent the admission of 
stones to the pulper. For this purpose it is lined on the entrance face with a 
plate of sheet-iron, which curved in such a manner as to form a small com- 
partment. The current of water dashes against this curved partition, and 
forms an eddy which forces the stones to fall to the bottom of the receptacle. 
Thus the cherry being lighter. is alone carried away by the current to the 
ulper. 
le Voprithstanding this arrangement, when the crop contains a quantity of 
stones, it is advisable to first pass the coffee and the water, which carries it 
away, into a little passage provided with partitions which effect the same 
purpose.

In this machine (Fig. 1) the fruit passes from the hopper against the: 
cylinder, which lies as close as possible to the counter-plate. This latter is in 
the form of a number of channels or gutters, the bottoms of which are movable: 
and easy to regulate according to the size of the fruit. The skins and a portion. 
of the pulp are carried away by the cylinder, whilst the berries fall through the 
channels of the counter-plate on to a sieve which oscillates rapidly, allows the 
pulped berries to pass through the perforated sheet iron, and delivers at one end 
the smallest berries which have not been torn. The perforated iron of the 
sieve can be changed according to the average size of the crop dealt with. 
The makers state that this machine is capable, according to size, of working 
off from 800 to 1,600 kilos (1,760 to 3,520 lb.) of cherry per hour. It weighs 
from 250 to 400 kilos (550 to 880 Ib.), and has a maximum speed of 120 . 
reyolutions per minute. 
The copper-plates of the cylinders are interchangeable, as well as the side 
pees of the channels, which are liable to wear away owing to the constant 
iction of the pulp. 
With this machine it is necessary to pass the smaller berries a second 
time through the peat but the same firm has constructed a more powerful 
machine which delivers every berry properly pulped.
