Processed pet food comes in many different types or forms, including wet (cans, bags, trays), dry (extruded or baked), cold-pressed, and raw. The label will state whether the pet food is “complete” or “supplemental.” “Complete” means that the product contains all the nutrients your pet needs for healthy bodily function in a daily ration, and is a “complementary” pet food, such as pet food. Treats need to be fed with other food sources to provide proper nutrition. Production methods and ingredients used vary depending on the format these pet food manufacturing equipment can complete

Dry pet food is made by mixing dry and wet ingredients together to form a dough. During extrusion, the dough is heated under pressure and then passed through a die machine that cuts the pellets as they expand due to pressure changes. The size and shape of kibble varies according to product specifications. The kibble is dried, cooled and sprayed. Some dry foods can also be produced by means other than extrusion, such as baking.

Ingredient Selection and Sourcing

Many ingredients used to make pet food are described as animal (or fish) derivatives or by-products. These ingredients are leftover parts of animals that meet the needs of the human food industry. Examples of by-products include liver, kidneys, lungs, and various by-product meals; all of which have been veterinarily inspected for human consumption. These ingredients come from the most common species in the human food chain. In dry pet food, animal derivatives are often used in meal form (e.g. chicken meal, poultry by-product meal) which are cooked, fat removed and the remaining material dried to form a dry meal. The by-products are also available in fresh or frozen form. Many other ingredients used in dry pet food, such as grains, grains, and vegetables, are in dry form and are milled or ground before being mixed. The formula may also contain the oils, vitamins and minerals needed to ensure the product provides all the essential nutrients.

Ingredients weighing and preparation

Ingredients are carefully selected according to pet food manufacturers’ specific formulations and are designed to provide complete and balanced nutrition for cats and dogs. Grind and sieve dry ingredients as needed, then blend.

cooking and cooling

The dry mix is mixed with the wet ingredients, water and steam in the pre-processor to hydrate the powder, form the dough and start the cooking process. The dough then goes into a machine called a pet food extruder, which cooks the dough under pressure. At the end of the extruder, the dough is expelled under pressure through a die plate, forming strips of a pre-specified shape, which are then cut to pre-specified dimensions using a rotary cutter as they expand.

After squeezing and cutting, the grits are air-dried in the oven to remove moisture, then cooled. Reducing moisture content is an important step in maintaining freshness and preventing food spoilage.

For baking, the dough is rolled out and cut into shapes, then baked in the oven (similar to a cookie or biscuit).

Coarse Grinding Coating

After drying and cooling, the kibble usually goes into a drum, where it is evenly coated with a spice blend to enhance flavor and coated with a preservative to keep the food from spoiling during its shelf life. Spices or other coatings may also be sprayed on baked goods as they leave the oven.

Package

Fill the package according to the declared weight and seal the package properly to prevent contamination.

Storage and Delivery

Packages are stored in boxes or wrapped on pallets and stored in warehouses, ready to be dispatched to customers.
