Problemas de peletizacion con urea en concentrados bovinos

Apreciada Alejandra, buenas noches:
Es importante que nos indiques si estas usando vapor ?? a que presión estas usando el vapor ?? Importante conocer como esta diseñada la línea de vapor ...
Si deseas puedes escribirnos para darnos a conocer la formulación que estás usando para poder aportar mas con la ayuda de Dios
Bendiciones

ALEJANDRA QUINTERO:

Te recomiendo estudies el siguiente tratado sobre peletizado:

https://www.cpm.net/downloads/Animal%20Feed%20Pelleting.pdf

En la página 17 encontrarás lo siguiente sobre peletizado de formulas con urea, y con melaza:

•Urea Feeds Little or no steam should be added to this group of feeds. Urea becomes more
soluble as the temperature rises. Steam supplies the heat and moisture to dissolve the urea.
When this occurs, the meal is wetter than meal without urea because the urea is acting as a
liquid. The hot pellet temperature should be no higher than 150°F. Thin dies (reduce frictional
heat) should be used to keep the temperature low. Fat (lubrication) added to the formula will
help. Too much steam causes choke-ups as well as severe bin hang-up problems. Normally high
pressure steam will be used.
•Molasses Feeds The amount of steam that can be added to this group is directly
proportional to the per cent of molasses in the formula. Since molasses is approximately 26%
water, the quantity of steam that can be added must be reduced or the meal will become too wet.
This condition will result in choke-ups. Adding live steam into the molasses line will raise the
molasses temperature to 200°F. Under these conditions, higher meal temperature can be
achieved without exceeding the maximum moisture level. Normally high pressure steam is
used.

Son buenas guías que pueden ayudar a resolver tus problemas. Ojalá y así sea.
