how much steam pressure and temp is required in extruder for floating fish feed

Mention was made of SME earlier. It is recognized that high levels of SME are required to make cat food and fish feed, typically not less than 35 watts per kilogram. This level of energy may be translated in reality into pressure, temperature and shear, which all

This moisture addition and a properly configured extruder barrel will result in a final pressure of the extrudate prior to the extruder die of 34 to 37 atmospheres, a temperature of 125 to 150 C and a moisture content of 23 to 28%.

Set these to the lowest value (in degrees C) that the machine is likely to experience. Indoor temperatures range from 10C-40C, but a value of 0 might be appropriate for an unheated workshop. If any sensor goes below the minimum temperature set here, Marlin will shut down the printer with a “MINTEMP” error.

extruder to process nylon are: fig 10: • barrier or 3-zone compression screw • compression ratio between 3.1:1 and 4:1 • length to diameter (L/D) ratio at least 24:1 or higher • 35% feed (preheating) • 15% compression (melting) • 50% metering

For low and moderate inlet steam pressure up to 120 bar, a single shell casing is used. With a rise in inlet pressure the casing thickness as to be increasing. Handling such heavy casing is very difficult also the turbine as to slowly brought up to the operating temperature.

Gelatinization occurs by mechanical means such as grinding, pressure, and by hot water. Soft feed at an environmental temperature of 25 C can be brought to a temperature of 85 C by the addition of 4 to 6 percent moisture from steam. Frictional heat due to

As to their manufacturing processes, FANWAY concludes as the following figure shows. Clearly, the difference between these two aquatic feed is the third step, that is, pelleted feed mainly uses pelleting mill technique while extruded feed chiefly adopts extrusion technology via high-performance fish feed extruder.

Almost all of these fish were produced in ponds and at least two-thirds of the feed fed was the extruded (floating) type. Feed conversion ratio in practice is near 1.7. Technology of formulating, manufacture, and feeding practical diets to catfish is advanced to the stage that highly productive and cost-efficient feeds are being produced; however, there are several areas which are still amenable to refinement.

The floatability of pellets of fish feed value ranged from 79.51 to 96.45%. The moisture content of pellets of fish feed value ranged from 16.68 to 17.82%. The water stability of pellets of fish

Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders.PM processes can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs.

These tests confirmed that good floating fish feeds can be made using the extruder and processes of the invention, even with low cost feed ingredients such as rice bran and soybean meal. SME values as low as 10 kWhr/T were achieved. The extruder was

This layout makes it possible to move, to mix, to knead and to build up pressure. In addition it can add water and steam and it can heat. The mash is briefly heated up to about 140 C and exposed to a pressure of up to 100 bar before it shoots through the die

Pack the meat into hot jars, leaving an inch of headspace. Add 1/2 teaspoon of salt per pint (a whole teaspoon for a quart), adjust the caps, and process pint jars for an hour and 15 minutes at 10
