Other forms: pelletized; pelletizing; pelletizes
To pelletize is to compress something into small nuggets. Companies that make food for rabbits and guinea pigs pelletize raw ingredients to produce feed that's an appropriate size for them to nibble on.
The technology of pelletizing is mostly used in factories and plants, to produce things on a large scale. Anything that needs to be squeezed together and formed into pellets, or small rounded pieces, gets pelletized. Businesses that make fuel for certain stoves pelletize wood scraps and pack the resulting pellets into bags. And drug companies pelletize medicine into tablets that can be swallowed or chewed. Pelletize comes from pellet, "little ball."
