DEFECTS IN EXTRUSION PROCESS AND THEIR IMPACT ON

toughness or fracture Overheating Moisture release Trapped air Contamination Extrusion Process The extrusion process converts a solid plastic feedstock material into a molten viscous fluid and then to a finished solid or flexible film product for practical use Extrusion equipment consists of a plasticizing extruder

To remove heat the vapor pressure is reduced using a remote (actually on top of the extruder) heat exchanger to cool the vapor The coolant boils uniformly around the entire barrel This is a very effective way of removing heat and is used primarily for extrusion of very heat sensitive materials

and in-barrel moisture Extrusion process was performed at 40C and screw speed of 200 rpm using a 4-mm circular die diameter The control starch sample was prepared without STMP and NaOH solution treatment All starch extrudates were cut to 1 – 2 cm size air dried at 60C for 8 hour grounded

Dec 01 2018The extruder motor amperage (P 0 001) and the mass pressure (r 2 = 0 92 P = 0 005) and temperature (temperature = 138 4 – 2 84 * mass moisture + 0 009 * mass moisture 2 r = 0 87 P 0 001) before the extruder die reduced quadratically with increased mass in-barrel moisture The extruder product flow rate increased (P 0 001) due to

Extrusion basics: Water water everywhere (but keep it

In extrusion as in Houston and Florida water is often an enemy Cosmetic—water absorbed by the resin will boil to steam as it leaves the die and make bubbles pits or dotted lines on the product surface It gets well above 100 C (212 F) inside the extruder but pressures are too high to permit boiling and the water stays in liquid form until its pressure drops as it passes through the

Figure 2 shows the response surface plot for the effect of extrusion conditions on BD Feed moisture had the highest significant effect (P 0 0001) on BD Low feed moisture had a decrease effect on BD (Figure 2(c)) while increase in barrel temperature from 110˚C to 140˚C led to a decrease in the BD of extrudates (Figure 2(a))

Experimental result showed that addition 25 % water to the formula gives a good performance of expansion ratio unit density and floatability than 15% and 20% moisture content Higher of screw speed produces feed with higher ratio expansion lower unit density and higher floatability

May 08 2008The plasticizing and lubricating effect of water became less marked as moisture content was more than 30% Thus greater moisture content did not facilitate plastic flow in extrusion process and only decreased paste compressibility Download : Download full-size image Fig 2 The value of extrusion pressure at the first of die

Aug 03 2017Ding et al studied the effect of extrusion conditions on physicochemical properties of rice based snacks and feed moisture was found to be main factor affecting the extrudate expansion The highest expansion (3 87) was reported at 14% feed moisture 120C barrel temperature and screw speed at 250 rpm

PHYSICAL CHARACTERIZATION OF EXTRUDED ANIMAL FEEDS

To summarize effects of ingredients screw speed in-barrel moisture levels and coating on buoyancy of aquatic feed were investigated and results indicated that extrusion processing can be used to produce aquatic feed for a variety of aquatic species including top middle and bottom feeders One patent disclosure and one manuscript are in
