Advantages of Pelleted Pet Food
- Pet pelleted food is made up of various compounds such as vitamin, proteins, minerals, fibers, sugars, and acids, which is not only can meet nutrient demand, but also can prevent the segregation of ingredients.
- Pet pelleted food can improve nutrient utilization due to heat treatment of the raw material ingredients. And it is easier to ingestion for pet.
- Pet pelleted food can save storage space and reduce transportation cost.
- During grinding and pelleting, dust and raw material waste is reduced.
How Dry Pet Food Is Made: The Extrusion Process
While there are numerous ways to making dry pet food, the most commonly used process is extrusion by a pet food pellet extruder machine. This process was adapted for making pet food in the 1950s based upon technology used to make puffed breakfast cereals. The diagram on Making Pet Food by pet food making machine illustrates the process:
- Ingredients are brought together in a mixing machine. Dry ingredients may be ground prior to introduction to wet ingredients. Once mixed together, they form a moist dough.
- The dough is heated in the preconditioner prior to introduction to the extruder.
- The pet food pellet making machine, essentially a giant meat grinder, is where the primary cooking phase for dry extruded pet food products occurs. The dough is cooked under intense heat and pressure as it moves toward the open end of the dog food making machine. At the end of the pet food pellet machine, hot dough passes through a shaping die and knife (similar to the action of a meat grinder) where the small pieces expand rapidly into kibble once they are under standard air pressure.
- Kibble is dried in an oven until its moisture content is low enough to make it shelf stable like a cookie or cracker. The drying oven is followed by a cooling phase.
- After cooling, kibble may pass through a machine that sprays on a coating, which is generally a flavor enhancer.
- Packaging (bags, boxes, pouches, etc.) is filled during the last step to precise amounts to meet the weight advertised on the label. The final result is finished pet foods or treats.
Pet Food pellet extruder Machine Working Principle
Extrusion can be defined as a technological process namely, forcing feed raw material in one or more of the following process conditions (such as mixing, heating, cutting, etc.) flow through the die, make material forming or eruption gasification. Making feedstocks from loose state into a continuous shaped dough, the resulting paste is extruded through holes in a metal plate. The diameter of the holes sets the diameter of the pellets, which can range from various different sizes.
Pet food pellet extruder machine, which can also make floating fish feed, applies the technology of extruction to produce pet food pellets from different kind of ingredients, extrusion is a process of cook the mixed ingredients under certain temperature, moisture and pressure. During the pet food pellet machine working, the temperature in the extruding chamber is 150-180℃ due to the electrical heater. The high temperature can kill bacteria and pathogen during machine running.
In the panel of the pet food pellet extruder machine there is a temperature indicator, once it reaches the set temperature, it will stop heating automatically by the reaction of thermocouple. During the high temperature ripening process, the starch and fiber of the raw material become swell. Then under the pressure-tight condition, material will be formed into pellets by shaping mold. At the end of the main shaft there us a cutter to cut the pellets to certain length.
