Thanks for that bit of info, however we are not set up at this time to apply additional liquids to the product. is there anything that can be done at the production end, as far as increasing/reducing steam, water, and oil. i have done many things to try and do this, but the only method that got me close was by having almost no steam, and alot of water. however this gave me a product that was unappealing to the eye. although it did float it just was not usuable. plus i also have a problem with it expanding, so i am wondering maybe their is not enough starch in the ingredients.IP: Logged |

Some processes can develop a non-foamed skin around a foamed core. I'm not sure how this is done.------------------

I hope that there is more information then that. as my experience with extrusion technology is limited. what i really need is ideas to procure a product, as i have exhausted all the ideas that i can think of. also i dont really understand what you mean in the last post!IP: Logged |

Free advice is not what it used to be.If you want something to float it needs a density less than water. This is usually done by incorporating voids in the poduct. Typically in food products this is acheived by having water in the formulation, heating the formulation to over 212F, keeping that mixture under pressure so as to keep the water as liquid, and then exiting a die where the pressure drops. The water then turns to stream and foams the product. The produt may need to be dried. A product with a lots of voids in it will float, but will also absorb water quickly, collapse and sink. If you can make the outside of the product (the skin) without holes, the skin will not absorb water as fast, and will not sink as fast. I believe there are some techniques to do as described above, but I still don't know what they are. Perhaps another expert can contribute. ------------------
