D.V.Sambasivarao,
Excess fats in the formulation can be arranged using a vacuum coater or a fats spray, in order not to hinder the expansion of collets. Its a post extrusion application.

But the same time we need to consider minimum 20% of starch in formulation of feed

Dear sir, higher protein content can not be impact always on floating of feed....mainly fat content can be impact on floating of feed.....whenever if feed protein content is lower or higher , mainly fat content of formulation only impact the floating...higher fat tends to high density and lower fat means lower density of feed( excellence floating)

I would like to add a few more comments regarding making sinking vs floating fish feed. 1. Floating or sinking pellets are dependent on the formulation. Both the type of starch and inclusion rate of starch will make a shaped fish feed float. Generally, sinking pellets incorporate less starch and higher fat, with post-fat application likely. 2. Additionally, the type of die plate used will help wit ...

Yes..land height is nothing but a land vertical length..need to use land height more than normal for bigger dia pellets....and also it will depend on fat level and type of extruder ( single or twin screw)...you can use 5 mm land for 7 mm dia die in fat levels between 4% to 6%..

200 mm to 250 mm open area per ton of production

Die open area is nothing but a number of holes required for die regarding formulas.....200mm to 250 mm per your of productionfor floating fishfeed.

Dear All Friends in the Industry,
All above items that being mentioned are very important like its starch level, particle size, conditioning, etc. also don't forget your die plate open area (you can set your own open area based on your formulation) so that you can have a bigger capacity and better quality.

I think temperatures up to 145 deg c are o.k....but extruder residence time 4 minutes is not possible...
