What the title says basically. How do they make fishing pellets?
"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 slowly and feeds suited to recirculation systems. The dry feed pellets are stable for relatively long periods, for convenient storage and distribution. Feeds are delivered in bulk, in large bags—usually one tonne, or in 25 kilogram bags. Smaller quantities of specialist feeds are supplied for use in fish hatcheries."
Ah, but in the absence of any Oompa Loompas with cordless drills, how are pre-drilled pellets made??
They're not drilled they are formed with a hole through them as they are extruded.
Child labour?
The hole that forms the OD of the pellet has a 'wire' at its centre to form the central hole in the pellet
By 'they' I assume that you mean the people in charge.
If the people in charge found out that you had obtained such information then you would most likely do a pretty rapid disappearing act before the info got any further.
This is basic porthole die construction - substitute base mix for Aluminium and add a 'pelletiser' a different diameter die for each pellet size..Porthole die extrusion of Aluminium in Manufacturing - YouTube
Hmm...you may need to refer to 'them' for this one. They might not be too happy about giving out trader secrets.
er...I think they cook them.
Owls make pellets.
