Preconditioning shrimp feeds, Part 4
Pressurized conditioners offer an alternative preconditioning technology to improve pellet quality, increase capacity and feed conversion and pasteurize feed.
Pressurized conditioners offer an alternative preconditioning technology to improve pellet quality, increase capacity and feed conversion and pasteurize feed.
Aquaculture feed manufacturers in the Americas – with the exception of a few countries like Ecuador – have relied on short-term, single-pass conditioners.
The effects of long steam preconditioning times of up to 30 minutes on the water stability of shrimp feeds were evaluated in early research studies.
To obtain highly water stable pelleted feeds, the mash should be preconditioned for more than 90 seconds at temperatures higher than 90 degrees-C.
