Distillers dried grains with solubles (DDGS), a good feed coproduct from the gasoline ethanol market, has been shown to become a viable potential choice protein origin for aquaculture feeds. To investigate this, three isocaloric (3.5kcal/g) component blends containing 20, 30, and 40% DDGS, with a net protein adjusted to 28% (wet basis, wb), were prepared for use due to Nile tilapia feed. Extrusion processing was then conducted using three DDGS contents (20, 30, and 40%, wb), three moisture contents (15, 20, and 25%, wb), three barrel temperature gradients (90-100-100C, 90-130-130C, and 90-160-160C), and five screw speeds (80, 100, 120, 140, and 160rpm) utilizing a solitary screw laboratory extruder.
Countless processing parameters, including mass flow fee, net torque required, certain mechanical energy consumption, obvious viscosity, and pressure and temperature of the dough in the barrel and die, were measured to quantify the extrusion tendencies of the DDGS-established blends. For all blends, as the temperature account increased, mass flow pace exhibited a slight decrease, die pressure reduced, and obvious viscosity exhibited a slight decrease as well.
Likewise, the net torque requirement, particular mechanical energy intake, and apparent viscosity reduced as screw rate increased, but mass move rate increased. Additionally, as china plastic machinery moisture articles increased, die pressure decreased.
At higher temperatures in the barrel and die, the viscosity of the dough was lower, leading to lower torque and specific mechanical energy requirements. Increasing the DDGS content, on the other hand, resulted in an increased mass flow rate and decreased pressure in the die. As demonstrated in this study, selecting suitable temperature and wetness content levels are crucial for processing DDGS-based element blends.
