From mash to hightech feed pellets

Posted by allenlu on November 22nd, 2019

Once feed ingredients are ground and mixed, they'll either be fed as mash or subjected to more process that typically involves heat or heat and pressure together. the foremost common sorts of this ‘thermal processing’ encountered within the feed business area unit pelleting, roasting, steam flaking, and to a lesser extent extrusion and enlargement. the most cost effective means of feeding pigs is providing them the mash, effort out the comparatively high-priced process techniques. With feeding mash it's vital that it's finely grounded in order that the animal will digest it properly. once the meal is just too rough, the feed intake and thence feed conversion quantitative relation may be negatively influenced, particularly in current times wherever animal feed is incredibly high-priced, because of the deficiency of raw materials within the world market. Feeding meal to animals has additional negative aspects, as a result of the feed isn't extruded with a particular warmth, sure pathogens aren't killed. These will produce enteral health issues within the pigs.
In addition, the digestibleness of the energy within the feed is alleged to be around four p.c less than ironed feed. The feed intake with meal may be lower that specially isn't wished by farmers that raise boars as they usually have a lower feed intake than feminine pigs.
Patented extrusion method
Over the years, feed corporations began to use additional process techniques to create animal feed. the foremost advanced means of manufacturing pig feed is extrusion by victimisation AN extruder machine. this system is often employed in the pet food and human food business, however not thus common within the production of pig feeds. Basically, AN extruder could be a long barrel with a gimlet within that is specially designed to subject feed mixtures to high heat and steam pressure. once feed exits the die at the top of the barrel, cornered steam blows off quickly, the soft heat pellets expand, and a coffee density floating pellet is made. Extruders area unit terribly versatile, and may build feeds with many alternative characteristics. Since many years, the Dutch animal feed producer Agrifirm uses (and patented) this system to create pig feed below the brand Air Line. many trials already tried that by victimisation the extruded pig feed the digestibleness of the feed is improved.
Agrifirm notices that with the present high feed costs farmers area unit evn additional targeted on digestibleness and feed conversion quantitative relation. The interest for the Air printing operation is so increasing. See: www.chickenfeedmachinery.com
