ABSTRACT
The article presents tests of influence of speed of densification piston (50, 100, 150 mm/min) and size of densified particle (1, 1.5, and 2
mm) on the values of maximum densifying pressures and the density of pellets obtained from a mixture of shredded oat bran with a 20%
addition of potato pulp. The tests were performed in an “open densification chamber - densification piston” working system, at a process
temperature of 70oC, with the use of a matrix with diameter of 8 mm and length of 47 mm. Increase in speed of progression of the densification
piston has an influence on a slight increase in maximum densifying pressures and a slight increase in pellets density, whereas increasing
the diameter of particles of densified mixture causes a reduction of both the densifying pressures and pellets density.
