Pet food machine / pet food production line

pet food production line

Pet food machine is the main production line of our company. It processes raw material into pellet to feed pet. The raw material can be grains, straw, vegetable, meat meal, bone meal, nutrition powder and so on. The final product is pellets with different shapes. The pet food production line can output feed pellet such as dog food, cat food, rabbit food, birdseed, fish feed, turtle food and many other general pets feed pellet. It’s widely applied to pet food industry, which is also the rapidly emerging industry in recent years. The complete pet food production line includes flour mixer, conveyor, extruder, oven, seasoning machine or flavoring line and cooling machine. The capacity of this line will depend on the extruder, and we also offer many options for customers to choose according to their demands.

Thanks to more and more people loving to keep pets, they also pay more attention to scientific feeding methods to keep their pets healthy. Since 2013, our pet food machine has been welcomed by many countries. Last week, we sold one plant to Brazil. It’s also popular with customers from Canada, Argentina, Spanish, Australia, Mexico, etc..   

Brief introduction of pet food production line

pet food production flow

Flour mixer→ screw conveyor→ twin screw extruder→ air conveyor→ multi-layer oven→ flavoring line→ cooling machine

The raw material goes into flour mixer after crushing (some raw materials also need one crusher). The mixer blends material into even and fine power, then the screw conveyor transfers the material into twin screw extruder. The extruder squeezes the material into pellets, the shape and figure can be changed by different molds. Air conveyor transfers the pellets into multi-layer oven, which roasts the pellets, removes the water and keeps the pellets storing longer. Flavoring line seasons the pellets, and increases palatability. The pellets comes out from flavoring line then goes into cooling machine, and gets cooled in case of metamorphism. Some customer will also choose to package the final product into bags to sell directly. So we also offer packing machine as an option.

Main machine introduction

  • Mixer. It mixes the powder of the ingredients well. According to the production line to choose different types of mixing machine, there are three types for you to choose.
  • Screw conveyor. The motor is used for power spiral transmission to ensure convenient and fast feeding.
  • Twin screw extruder. The main machine of the whole line, which also decides the capacity of the whole plant. The screw material adopts the alloy steel (38CrMoAL). The raw material can be corn flour, grain flour, meat meal, bone meal, fish meal, etc.. The specific product shape can be changed by different molds.
  • Conveyor. The conveyor sends the feed pellets to the oven, the height of the conveyor is determined according to the oven. Customer also can choose the air conveyor.
  • Multi-layer oven. The oven is mostly electric oven, the temperature is between 0-200 degrees through the control cabinet to adjust by itself. The internal of the machine is stainless steel double-mesh belt. Baking time can be adjusted according to the quantity of layers. It can be three, five, seven layers of stainless steel oven. The baking time will depend on the capacity.
  • Flavoring line. There are octagonal flavor cylinder, single drum, double drum flavor line. We will make the configuration according to the specific output and the nature of the product.
  • Cooling machine. This part adopts water-cooled circulating drum. Used for preliminary cooling and conveying of products.

Successful case

    In October we received an inquiry about cat food making machine from a customer of Brazil. He used to be a worker of a dog food manufacturing factory, who noticed the cat food making industry was also raising rapidly in Brazil. Thus, the customer decided to build a factory himself and produce scientific, and good quality cat food. He planned for about half of a year and came to us about manufacturing plant. Due to our professional technical suggestions and design of plant layer, finally he chose us. This customer wanted to customize the shape of the pellet, we accepted his request and showed the sample of mold and the output of the customized shape to him. Delightfully he was very satisfied with effect. He paid the deposit last week and now his machines are under production.


1.What’s the material of the the machine?

The sheating material is made of 201 stainless steel, screw is alloy steel (38CrMoAL), the barrel of the machine is 45# carbon steel.

2.What can be raw material?

Grains, meat meal, and so on.

3.What’s the capacity of the production line?

Two models of line, one is 150kg/H, another is 250kg/H.

4.Can I know the recipe of the pellet?

Yes, we can provide one after you buy the machine.

5.What’s the heating temperature?

160°, it’s adjustable.

6.Can I have different sizes of mold?
