and conference” in Manila on May 25, 2017
Extruders can be visualised as a high temperature short time (HTST) device that can transform a variety of raw ingredients into intermediate and finished products
Extrusion technology provides several different advantages over traditional
methods for feed processing. While many processing technologies result in an
agglomerated feed, only a few have sufficient energy inputs to ensure feed
safety.
Feed safety is a major factor in choosing extrusion-based methods over traditional pelleting methods. Extrusion is a hydro-thermal process where the critical process parameters of retention time, moisture, and thermal and mechanical energy inputs can be varied over a wide range.
The feed industry has considered a provision to mandate that all feeds are pasteurised and some form of extrusion will likely be implemented as the processing method of choice. Extrusion is a highly versatile operation that can be applied to a variety of feed processes.
Extruders can be used to cook, form, mix, texturise and shape feed products under conditions that favor quality retention, high productivity and low cost. There are several ingredients that need some kind of processing to make it more digestible and palatable to use as feed ingredients.
There are several agriculture by-products that can be processed into value-added ingredients for feed application. Therefore, adding one extruder to a feed milling operation can add value to the ingredients and by products.
At the same time, a feed miller can reduce the effects of mold, fungus, microorganisms and other anti-nutritional factors in these ingredients. The Philippines is producing an annual compound feed of about 13-15 MMT, about 40-45 percent are swine feeds, 20 percent layers, 20-25 percent broilers, three to five percent Aqua, and the rest are specialty diets such as pet foods, fighting cocks, etc.
