I totally agree with you Doc, feeding broilers on pelleted feeds enhance a positive growth performance on the birds in terms of final live weight, FCR and reduce feed wastage thereby reducing the cost of production.

Good article on pellet vs mash
My reply to Mr Ambalkar on producing pellet without steam.
Pl note that steam requirement for geletinization of feed particles and for also increasing the temp of mix feed to the tune of 75 degree and above so that at high temp and pressure material can pass thru die of 3 mm to make compact pellet
Pellets are complete feed

Dr Chandra thanks for kind information, but my question is why to use steam generator for steam if 75 degree temperature can also be set during drying stage of pellet in dryer. But pellet size is definitely would be large say 8 mm which maybe crumbled for desired particle size.? I just want that other way round can we eliminate steam conditioner from entire pellet processing and final production.
With regards,

Dear Sir
Regarding to use no steam at all at pellet process, it's feasible, however it's also a fact the power consumption it's increased without steam.
To rise such amount of mash temperature (65-75° C), require about 35-50 kgs steam @ 1.7 bar 2720 kJ/kg in order the produce the enthalpy, this is because the gelatinization it's given after steam energy transfer (enthalpy) to the mash previously to get contact with the die hole where help to pass as lubricant thru the die.
The saturated hot water at 75°C has only around 315 kJ/kg, very few energy to get gelatinization.

Dear Mr. Ambalkar, in pelleting process you can't omit the conditioner since it is one of the Important part of the process since at conditioner you are cooking the materials to make it gelatinize for better digestibility, second it sterilize the compound feeds, third it will help to increase your throughput of your pellet mill with lesser electricity costs. Forth, you will have better FACT if you use pellets for your birds. At pelleting process you don't need a dryer you just need a cooler unless your process is an extrusion.
Actually, 75° still at low side ideally it must be 80-85°C conditioner temperature to have proper gelatinization. Please consider also your retention time at conditioner. I hope I help you. Thank you.

Dear Sir,
I mean wet pelleting with increased moisture percent and then use of dryer . As dryer is easy to handle and operate in comparison to steam generator? The process of production should be short and would also reduce manpower requirement at small farmer's level not at commercial level? May kindly comment.

Sir,
I have produced good quality pellets without steam conditioning and results are encouraging however, I believe more techno commercial research is required from small and scattered farmer's view point.

Ambalkar Please check micbiology testing status means pathogenic analysis. If no pathogenic threats with your dryer, having good PDI, good FCR , It's good if cost effective for small scale. Validate the dryer time

Dear colleagues. Help to solve the problem with the quality of the granule. We produce fodder for fish, but our PDI is not very good.
What is the consistency of raw materials from the air conditioner?
What temperature should be the raw material on leaving the air conditioner?

Sorry, not the air conditioner, but the pre-conditioner

Dear Rene, thank you for your recommendation. We did as you recommended and the quality of the granule improved noticeably. Especially the appearance.
Also, we constantly grind the inner surface of the die holes. From prolonged work they wear out and spoil the surface of the granule.
But as before, we can not achieve water resistance over 4 hours.
Tell me please what kind of binder is better to add and in what proportions, so as not to harm the health of fish?

Moisture control of pellets is most important. IT can make hard or very soft pellets. Additional water and steam are crucial part

Good discussion on the topic. Elevated tempt essentail to control pathogenic/ Microbial count in the feed.
