The difference between dry and wet pet food dog food

The processing range of pet food and dog food is very wide, including pet snack food, tooth cleaning sticks, bone, bone pressing, nutrient (liquid), concentrated dog food powder, dry food, wet food, semi-dry food, canned food, etc. In order to maximize its nutritional functionality, different raw materials are processed in different forms

The processing range of pet food and dog food is very wide, including pet snack food, tooth cleaning sticks, bone, bone pressing, nutrient (liquid), concentrated dog food powder, dry food, wet food, semi-dry food, canned food, etc. In order to maximize its nutritional functionality, different raw materials are processed in different forms.


Joyang company analyzes and compares two different puffing methods in the puffing process of dog food. There are two kinds of puffing by screw extrusion, one is dried type, and the other is wet type.


Dried type needs to add water to the raw materials in the mixing processing. As the core machine of pet food production line, twin-screw extruder is the direct determinant of pet food shape, degree of raw materials cooling, degree of expansion, product size and taste. The various output pet food extruders developed and produced by Joyang company can meet the output needs of small to medium and large production lines.


The difference between the wet type method and the dry type method is that the raw materials are prepared in advance before entering the extrusion, and the temperature is increased by steam or water and pre-cured. The so-called conditioning means that the raw material of pet food is heated and humidified by steam, so that the starch in the raw material is pre-gelatinized, the protein is denatured, and the raw material is softened.


At the same time, the wet type method also has the advantages of good puffing granulation effect and stable puffing rate. In the process of dog food processing, the wet puffing method and pre-conditioning technology have a very important role and significance.
