henward Posted October 20, 2011 Report Share Posted October 20, 2011 thought of something just now... god knows how and why lol but how do they dry fish food, do they cook it in the oven or dehydrator? ... i know they make it sink or float by density, but drying. pellets are not freeze dried.... i assume it starts of wet, then turned into granules, and dried? anyways, saw a programe on how they m ake matches, interesting stuff! so yeah, curious lol Quote Link to comment Share on other sites More sharing options...
Caryl Posted October 20, 2011 Report Share Posted October 20, 2011 We were given a very interesting talk and video from the Masterpet guy from Australia. It showed how they make the fish food (virtually no human involved in production - not in the food either ). I can't remember much about it though (thank you drugs ). Can someone else remember the method? I think they were large kilns. Quote Link to comment Share on other sites More sharing options...

No more moisture than necessary for them to stick together. When it goes through the pellet machine and compressed into pellets it heats up quite a bit which causes a lot more of the moisture to evaporate out.

Zayne Posted October 20, 2011 Report Share Posted October 20, 2011 you would think they would dehydrate it not cook it, but im not too sure Quote Link to comment Share on other sites More sharing options...

Ira Posted October 21, 2011 Report Share Posted October 21, 2011 coo machine, can make human feed too:D efficient feed. yeah, cooking can destroy goodies right? It's not really cooking. It just gets hot and not for that long depending on how big of piles they put it in. I suppose if you have one producing thousands of KG/day and dump it into a big pile it would take hours or days to cool off. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted October 21, 2011 Report Share Posted October 21, 2011 They use heat for a number of reasons. Moisture evapourates more at higher temperatures. Heat can denature proteins and cause advantagious changes to the chemical nature of the product. Heat or rapid heating and cooling can be used to pasteurize or sterilize the product.
