Ornamental fish require a wide range of pellets, from floating pond feed to dense cat fish chips, which sink very fast. Our twin screw extruder technology delivers the flexibility you need, minimizing cross-contamination and delivering high productivity.
Apr 1, 2004 · Extrusion cooking involves the application of mechanical energy supplied by the shearing and mixing action of the extruder screws. During the process, a formula mix is transformed from a powdery, free-flowing meal into a dense, compact powder.
Fish feed for or aquaculture. Brabender laboratory equipment and extruders for the development and optimization of fish feed for the aquaculture industry. In addition to our modular product line, we also offer tailor-made solutions for your individual needs.
There are two kinds of extruders that might be used in aquafeed production: the single-screw extruder and the twin- screw extruder. Single-screw extruder: As its name implies, a single-screw extruder has only one extruding screw and is of simple structure, so its price is relatively lower.
Aug 1, 2004 · In the aquaculture industry, extruders have been used to produce a great variety of products, but today most of these feeds fall into the sinking or floating categories. To understand how extruded aquafeeds are produced, one must first understand how extruders work.

4 days ago · The feeds are made either using a pellet mill or extrusion. The choice of the process primarily depends on what type of feed would be made for most part of equipment running time. The feeds are generally divided into different types based on their buoyancy - sinking, slow sinking or floating type.
