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. 



SEPARATING THE SEED 



FROM THE WASTE 



MATERIAL. 



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 

 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
