We trial products with high fat. The fat before extruding around 7-8%. Using a single screw with high shear screw configuration and with die design for floating fish. The issue with the product is the size between the front and end is not symmetrical. What is the root cause of this issue? Is that from machine process or raw material?

D.V.Sambasivarao Last time i testing more with the longer land length from 4 mm to 6 mm but the issue not been solve.I'm not sure that other factor that i need to be checking more?

Sankaran Suresh Sundaram For the die plate I'm not sure that which factor is the main one that i should change to solve this issue. Like the picture above we use die diameter 7 mm with 33 holes and the die land about 4 mm. thckness.

Sankaran Suresh Sundaram On extrusion cooking being completed the starch should bind the product string enough not allow any variation in expansion. However it is very unlikely that product expansion alone is the problem. One would have to look at the die plate and die holes more closely. Take a product like kurkure, which has multiple expandable starches will surely have this same variation.

I should think the die design could be the problem in the cutter, If extrusion process is complete and cooking has taken place to the desired extent then the vagaries of pellet shape front being larger than the rear might not have anything to the recipe. Dry Extrusion can process recipe vontsining just 7 to 8 % without any problem. Also the thickness of the die plate would be minimal and therefo ...

D.V.Sambasivarao Ok thanks for your information. If the fat in formula is more(more than 6%) i have to increase the land length more right?

D.V.Sambasivarao Land height you mean same as land length right? Do you have number criteria for big diameter to be sufficient? We used diameter around 7 mm.

Faizan Ali The mix moisture around 8%. The starch source we use normally starch like from corn.
