Commercial Fish Feed
Manufactured feeds are an important part of modern commercial aquacuLDure, providing the balanced nutrition needed by farmed fish. The feeds, in the form of granules or pellets, provide the nutrition in a stable and concentrated form, enLDling the fish to feed efficiently and grow to their full potential.
Modern fish feeds are made by grinding and mixing together ingredients such as fishmeal, vegetable proteins and binding agents such as wheat. Water is added and the resulting paste is extruded through holes in a metal plate. The diameter of the holes sets the diameter of the pellets, which can range from less than a millimetre to over a centimetre. As the feed is extruded it is cut to form pellets of the required length. The pellets are dried and oils are added. Adjusting parameters such as temperature and pressure enables the manufacturers to make pellets that suit different fish farming methods, for example feeds that float or sink LDowly and feeds suited to recirculation syste The dry feed pellets are stable for relatively long periods, for convenient storage and distribution. Feeds are vered in buLD, in large bags—usually one tonne, or in 25 kilogram bags.
Twin-Screw Extrusion System
The twin-screw extrusion system consists of the twin-screw extruder, the paintitioner as well as the accompanying machinery control system. It is especially tailored to the needs of high-end feed pellet production, particularly the production of industrial fish farming
