A lot of dependen ies on expansion what running conditions what formula do you want radial or axial expansion

If you don't mind me asking, what extruder are you using? Do you have water flow meters connected to the extruder water supply? Adding water to the mix is really old technology and not accurate enough as you will probably rehydrate the formula unevenly. Are you trying to make floating or sinking? I would cool the extruder to give around 90 as a final head temp and see how you go. take 0.5% from co ...

NKWOCHA OBED the temperature is probably far too hot. I would expect to see these kind of temperatures extruding cheetos or other light density products. Do you have the ability to cool the heads or add 1% oil into the conditioner? How much water are you using? It sounds like the cook is out of control. Can you use a less aggressive screw configuration or slow the extruder shaft?

NKWOCHA OBED what is the head temperature? What is the formulation? There are many blockage causing items and a suggestion would need more information.

Denis Dimovski Denis, how much Sunflower are you adding? Is this dehulled, have you calculated capacity versus die open area. 80 mesh is very fine and may not be helping 400 micron should work well. What is your target density?

I would also suggest that we dont have a detailed screw configuration, Denis has the configuration changed? is this the same machine you have used for years? are the screws and liners worn? has the formula changed? could you use hot process water say 60-70c ? you mention 600rpm shaft speed, is this the input shaft at 25htz or the actual extruder shaft speeds? my thoughts are that you seem to be o ...

Denis Dimovski Hi Dennis you may find that by using a better quality starch source you can drop the level below 10% also depending on the screw profile 600 rpm extruder speed is very high for sinking feed. does the extruder have a preconditioner
