Pet food extruder MACHINE
A pet food extruder is specialized equipment designed for the stable production of expanded feed like cat food and dog food.
Within the extruder, raw materials go through mixing, heating, cooking, expansion, and shaping. This process transforms them into various products – from small kitten kibble to large dog bites, and from basic diets to functional formulas.
To meet production needs for various scales and product types, RICHI offers two types of pet food extruders:
Single Screw Pet Food Extruder
Cost-effective, ideal for producing standard expanded cat and dog food, meeting most common formula requirements.
Twin Screw Pet Food Extruder
High adaptability and strong mixing capability, specifically designed for premium pet foods, grain-free recipes, functional foods, and other products requiring higher expansion levels or specific densities.
single screw pet food extruder Machine
If you want a machine that doesn’t require a big investment, works reliably, and is more than enough for producing regular cat or dog food, then a single screw extruder is the perfect answer.
SKF bearings
+
The bearings in the transmission box are made of SKF bearings, which can ensure long-term stable operation.
Feeding system
+
The feeding system adopts a uniquely designed silo with no sediment to ensure smooth feeding.
Fully automatic control
+
Fully automatic control system enables one person to control multiple machines, thus improving labor productivity.
Large output
+
Effectively distribute the reasonable shear force in different areas of the extrusion cavity, effectively increasing the output while ensuring high quality.
Working Principle
Using one screw to handle raw material conveying, mixing, cooking, and extrusion shaping.
The materials are gradually heated and pressurized within the barrel. When pushed out through the die, they expand rapidly and form pellets.
This entire process is stable and continuous, making it easy to control the shape and density of the final pellets.
Applications
Daily mass production of regular cat kibble and dog kibble.
Processing plants looking to produce standard formulas and economical product lines.
Plants with limited equipment investment budgets.
Products requiring moderate expansion levels and standard densities.
Advantages and Features
Lower Investment: For the same capacity, single-screw machines cost much less than twin-screw ones.
Lower Energy Consumption: Overall energy use and running costs are more manageable compared to twin-screw systems.
Ideal for Standard Products: Meets most market demands for regular cat and dog food.

Working Principle
The twin screws work together by meshing, achieving stronger mixing, more precise cooking control, and more uniform material conversion.
Perfect for refined production of premium pet food.
Applications
High-end cat/dog food (grain-free, freeze-dried topper, functional formulas, etc.)
Difficult-to-process recipes like high-protein, high-fiber formulas.
Brand-focused factories aiming for higher texture quality & better expansion control.
Advantages and Features
Fuller pellet expansion, adjustable density, finer texture.
Handles grain-free, high-meat, hypoallergenic, or specialized functional foods easily.
Continuous, Stable Production: Ideal for
long-term, high-load operation in medium/large factories.

FAQ ABOUT PET FOOD EXTRUDER MACHINE
If you have any questions about pet food equipment and pet food production, you can first take a look at these answers.
1. Can your pet food extruder make other pet foods besides dog and cat food? Like for ornamental fish or birds?
+
Yes, absolutely. Our pet food extruders have a very wide application range. They can not only produce dog and cat food, but also process ornamental fish feed, bird feed, rabbit food, hamster food, reptile diets, and even some specialized lab animal feeds.
Just provide us with your raw material formula and the target pet species, and we can help adjust the process parameters, select the suitable die, to achieve production of pellets in different shapes, sizes, densities, and textures.
As for the price of the entire shrimp feed production line, I need to understand your specific needs first, and then let our engineering designers customize a production plan for you. Only after the shrimp feed production plan is determined can we calculate the price for you.
Many clients use one production line to manufacture multiple types of pet food, saving investment while expanding their product line.
2. Can you adjust the hardness and size of the extruded pellets? Can they suit different breeds and body sizes of pets?
+
Certainly. The machine is equipped with various dies. Pellet diameter can be flexibly switched between a few millimeters to over ten millimeters, meeting the needs of young animals, small pets, medium-large dogs/cats, and other pets.
Regarding pellet hardness, it can also be controlled by adjusting the extruder’s temperature, moisture, pressure, and screw speed. For example, puppies/kittens need smaller, softer pellets, while large dogs require harder pellets to exercise their bite force. Switching dies only takes a few minutes, and adjusting process parameters can be done quickly via the touchscreen panel.
3. What is the difference between dry extrusion and wet extrusion when producing pet food ?
+
The main difference between dry extrusion and wet extrusion is that the wet extrusion food extruder machine is equipped with a modulator and requires saturated hot steam to be introduced during the working process.
Dry extrusion is mainly used in the production of pet food with small capacity and low investment. Compared with dry extrusion, wet extrusion can improve the quality of pet food pellet and increase the capacity of pet food to a certain extent.
However, whether to choose dry extrusion or wet extrusion to produce pet food still requires comprehensive consideration.
4. I want to buy pet food extruder machine, can you tell me the price of pet food extruder machine？
