PROCEDURE IN HAN- 
DLING TOMATO 
WASTE. 
Two important steps 
are involved in pre- 
paring tomato seed for 
oil production : The 
separation of the seed 
from the wet waste 
material and the dry- 
ing of the seed.

The wet mass of 
seeds and skins as it 
comes from the pulp- 
ing operations is 
known as "cyclone 
waste," 2 and several 
methods may be em- 
ployed for separating 
the seeds from this 
waste. The common 
practice where only 
small quantities of 
seed intended for 
planting purposes are 
involved consists in FlG - 2 - 
suspending the waste 
in several volumes of water and agitating the mass. The skins, being 
lighter than the seed, have a tendency to float, while the seeds and 
cores sink. 
In large-scale operations 3 the waste is discharged into a long trough 
provided with a false bottom, the mesh of which is of a size which
