PURPOSE
As the name shows, it is used to coat agglomerated products with a liquefied material.
In the feed industry, for example it is used to coat some pellets with fat or sugar material in order to improve the nutritive value and favour the appetence.
The grease incorporated into the mixture gives good results, but the percentage is limited according to formulas (3.5% on average, 8% on an Alfafa base ration), as it decreases the quality of pellets; the excess must then be coated.
The spraying
The spraying is usually done on cold pellets (up to about 8%), the percentage varies according to the dimension of pellets and to the mixture ingredients.
The inconvenience of spraying on hot pellets ensuring a temperature uniformity is a limited penetration due to the moisture level in the product.
Spraying on cold pellets followed by heating and another cooling ensures a maximum penetration (the grease being solidified before being completely absorbed), but this technique is much more expensive.
