Multi Functional Pet Food Making Machine / Cold Pressed Dog Food Extruder

The Model 135 pet food extruder is a highly efficient and energy-saving professional feed production equipment. This machine utilizes

advanced extrusion technology, enabling materials to be instantly cooked and shaped under high temperature and pressure, effectively

improving the digestibility and absorption rate of pet food. Its simple and compact design makes it extremely easy to operate, while also

boasting a significant advantage in high output, meeting the large-scale continuous production needs of large fish farms and pet food

manufacturers. This equipment is specifically designed for producing nutritionally balanced cat food, dog food, and floating fish food,

with excellent stability in water. Furthermore, the machine has low energy consumption, conforming to environmental protection and

energy-saving principles, effectively reducing operating costs, making it an ideal choice for large-scale production of high-quality pet

food.

Applicable animal types: Cat food, dog food, floating fish food, turtle food, bird food, shrimp food, etc.

In pet food production, a single-screw extruder first mixes various nutritional ingredients (such as grain powder, meat meal, vitamins,

and minerals) according to a scientific formula, adjusting the moisture content to approximately 20%. This appropriate moisture level

is beneficial for subsequent conditioning and gelatinization without causing excessively high viscosity.

Next, the mixed ingredients enter a conditioner for stirring and high-temperature steam conditioning, causing initial gelatinization of

the starch and softening of the material. Subsequently, the material is fed into the single-screw extrusion chamber. Under the powerful

rotation of the screw, the material undergoes intense compression, shearing, and friction, converting mechanical energy into heat

energy and rapidly raising the material temperature. An adjustable heating ring is also installed externally to further assist in heating,

ensuring the material reaches the required gelatinization temperature quickly, thus significantly improving expansion efficiency. The

moment the high-temperature, high-pressure material is ejected from the die orifice, the pressure drops sharply, moisture vaporizes,

and porous, loosely packed extruded pellets are formed. By adjusting the cutter speed, the length of the finished pellets can be precisely

controlled to suit the feeding habits of different pets.

There are many raw materials for feed extruders, such as corn, soybean (bean cake), fish meal, bone meal, animal waste, and so on.

The extruded feed can have various flower patterns. The mold can be customized according to the requirements. The product outlet is

equipped with a rotary cutting device with variable frequency speed regulation, which can adjust the rotation speed of the blade arbitrarily

to control the speed and length of the cutting. The feed is novel in shape, unique in taste, rich in nutrition, and delicate in organization, and

 is suitable for feeds with different pet tastes such as dogs, cats, fish, birds, rabbits, shrimps, minks, and foxes. Suitable for farmers, small

and medium feed mills, and research institutions.

Product structure and advantages: The feed extruder is composed of a main motor, a feeding motor, a cutting motor, a feeding hopper, a

heating device, a base, a screw, a screw sleeve, an electric control cabinet, etc.

The semi-finished product after extrusion molding contains a high moisture content and needs to be dehydrated by hot air in a dryer to

reduce the final moisture content to below 12%. The dried pellets can also be flavored with oil spraying, coating with flour, and other

seasoning processes to enhance palatability. This special pet food produced in this way has the advantages of comprehensive and

balanced nutrition, high digestibility and absorption rate, and can be fed directly without additional steaming or cooking. It also has low

moisture content, a long shelf life (usually over 12 months), and the dry, loose pellets are easy to carry and store, greatly facilitating

daily feeding for pet owners.

A feed extruder can be combined with a crusher, mixer, conveyor, dryer, air conveyor, seasoning machine, etc., to form a production line.

It can work continuously, save labor, and improve efficiency.
