One of the most important and at the same time underestimated steps in feed production is the proper cooling of pellets. Here at Shanghai Yuanyuda International Trade Co., Ltd. we have witnessed the beneficial effects that proper cooling can have on feed quality and shelf life. And here are the reasons why you should pay your complete attention to pellet cooling:
The Science of Pellet Cooling
Pellets leave the machine at 70-90 o C and 15-17 percent moisture. Devoid of apt cooling:
Moisture migration takes place through residual heat
Nutrients are broken down by enzymatic reactions.
Mold spores get an optimal place to grow.
main Advantages of pellet cooling
Moisture Control
Dries down to 8-10% moisture content making an unfavorable environment to the survival of moulds and bacteria. Our counterflow coolers can do it in as little as 5-8 minutes.
Pellet Hardness enhancement
Slow cooling enables starch recrystallization that enhances pellet durability by, up to, 30%. This implies reduced breakages when handling and transporting.
Nutrient Preservation
Quick chilling preserves vitamins and other heat labile additives that would otherwise be destroyed. Tests indicate that correct cooling can retain 95 percent of the vitamin C activity of the pellets as against 78 percent in pellets that have not been cooled properly.
Storage Stability
Pellets that are cooled 2-3 times longer in storage remain in quality. Our customers complain:
50 percent decrease in spoilage cases
Shelf life increased to 3-6 months long
More regular animal feedings
Cooling Solutions by Yuanyuda
We sell full cooling systems of:
Livestock feeding (10-200 T/H)
Water meal (soft cooling of delicate pellets)
Special corrosion-resistant models of organic fertilizer
Both systems have:
Smart climate system
Aerodynamic efficient energy flow design
Stainless steel parts are easy to clean.
The Price of Inefficient Cooling
A 10 ton/hour feed line which runs at 90 percent efficiency may lose $15,000 per year due to:
Nutrient decay (20% loss)
Mold contamination (5 percent rejection rate)
Pellet breakage (8 pellets loss)
A proper cooling investment will usually pay its way in 6-12 months by cutting wastage and increasing feed conversion ratios.
