Dear all, Extruder is energy intensive machine we can save energy for sinking feed by using pelletizer, however extruder are used for making floatable feed. Now meeting all ends possible such as optimum processing, nutritional and feed safety and cost balance and also easy access and availability of raw ingredients is very complex task. But we need a machine that is versatile one and can solve ...

How can I use single screw extruder for fish feed to make pet food I need the parameters of heat / water / steam cooking time

As I understand from the comments of Mr. Lu you have a Zheng Chang extruder. He mentioned that screws are different for sinking and floating. This is most likeley only the case for this machine. Normal twin shaft extruders you do not need to change the screw or even screw patterns for sinking and floating products. This is one of the advantages of twin shaft extruders. Due to the forced transporta ...

As we know, the worms (screws) for sinking fish feed and floating are different. The production of sinking fish feed needs a lot of information and needs to do commissioning on site. It is better to ask the engineer to check on site.

This looks like cold extrusion in the old days and there will be limited cook to the dough and you have to heat it up by means of mechanical energy input and creating friction in the extruder. Its aquestion of time, temperature, water content and shear . With 30% of water you have sufficient water to gelatinize. The question is do you have sufficient temperature and time in the extruder; only a m ...

I'm glad that with my problem we open something that is interested and good to share each of us For any help that i can do and with my knowledge for extrusion please post and we can keep these channel open for discussion. Happy Holidays Denis

By decreasng the temperature and speed of screw rotation in the barrel may help you.

Gentlemen; With a lot of appreciation I can see how well known manufacturers such as Anderson International (represent by us R&D Equipment), Buhler, Insta-Pro, Andritz, Wenger and others participate on this kind of discussions, this is the type of feedback and information we need to create and share on this Community; with surprise I can see how the Spanish Community can have 200+ participations ...
