According to different varieties and growth stages, producing puffed floating fish feed that is suitable for their caliber and nutritional needs can well meet the feed needs of conventional aquaculture and special aquaculture, which not only facilitates aquaculture producers but also promotes production development.

With the increasing awareness of environmental protection, more and more people are paying attention to the issue of biodegradable materials.

Expanded feed is a full price formula feed that is produced through a series of processing processes such as raw material micro crushing, batching, mixing, expansion, granulation, drying, spraying, cooling, screening, packaging, etc., with characteristics of floatability, semi sedimentation, and sedimentation.

Expanded and precipitated granular feed is easy to absorb water and soften, suitable for gnawing, and can also reduce the loss of debris generated during gnawing, reducing feed waste and water pollution. Moreover, the expanded feed has a long water resistance time and a high degree of maturation. Twin screw wet puffing machines are commonly used for producing puffed feed.
