Expanders in feed meal

Thank you very much Dr. Rakesh.
Do you know if there is a formula for this energy improving? Can you recommens any books about expanders and extruders?
On the other hand, I see in India some product -methionine from plants, which can replace dl methionine 1:1.
Do you know anything about that?
All the best

Dear Ing Dragan lonut, 

The most important aspect of pelleting is conditioning time of the mash co factored with moisture, temperature, mechanical shear, pressure of the steam at the conditioners opening . Lower pressure reduces the heat carrying capacity of steam which leads to condensation thereby affecting gelatinazation of starches and pellet durability. Therefore coating of conditioner with hot seal is must to overcome this problem.

Thanks

Does anybody have experience with near infrared systems, this lab devices or processes allows to determine key parameters on the quality of pelleting, or expansion systems since it measures the degree of gelatinization, moisture, proteins, etc… From my point of view, when using pellet or expansion systems, parameters must be verified beyond the conventional to ensure the best quality of the product. 

Dear Dr Rakesh,

We are experiencing durability and rough texture of our pellet product. How can we overcome this problem? We try to increase the temp. at 80-85 deg. 500 feed RPM and steam press of 2.2 bar. Please advice us.

Thank you!

Dear Cedric Maxwell,
When pellet durability is concerned maintain steam pressure at 3.5 bar . We need to check feed formulation (recipe ) to assess pellet ability of the feed and pellet durability .
Thanks 

Dear Mr. Biggliani 

Here are the specs.
Feed Type: Lactation and Gestation 
Pellet Size: 4 mm 
Die L/d ratio: 2.5 mm
Moisture before the conditioner: 14.9 
Moister after the conditioner: 23.2
Temp. of feed before pellet chamber: 83
Steam press.:2.2 BAR
Conditioner RPM: 3262
Ave. Particle Size: 700 microns
Screen Size: 3.0 mm

Thank you and we appreciate for helping us and giving us new ideas.

Dear Mr. Ing. Dragan Lonut

Regarding your question we don´t have expander, only conditioning and pellet. What would be the contribution of that binder?
