In aquafeed, you can find three types of pellets: floating pellets, sinking pellets, and slow-sinking pellets, because not all aquatic species eat at the same height of the water column. In the case of bottom feeders such as shrimp, river crab, sea bass, and some species of catfish, they eat sinking pellets. Contrary to tilapia and carp that feeds from the surface with floating pellets. Sinking pellets production must control water stability to preserve the quality and form of the pellets, avoiding nutrients' dissolution in the water.

Sinking pellets

A servant boiled drinking water for his emperor when leaves from the Camellia sinensis tree fell into it – and the emperor decided to taste the drink. While to make tea nowadays on a medium to large-scale you need tea processing equipment like dryers instead of just a tree and wind blowing it, mythology adds a special flavor to the tea industry story.

Building a fire with wood sticks and logs is one of the most wholesome experiences. But it would take a lot of trees to heat up our homes. Instead, the fire-stoking power of plant material can be concentrated in a wood pellet, boosting its burning efficiency. However, wood pellet making equipment and machinery involves more than just the compaction of sawdust. Processing high-quality pellets from biomass can be as intricate as loading a fire-lay.
