Dry Screw Pet Food Machine 180kg/H-200kg/H Dog Food Production Machine

This pet food machine is designed for producing various pet foods, including cat food, dog food, fish food, turtle food, and parrot food,

and is widely used in homes and small-scale processing settings. Its core process utilizes extrusion technology, using a high-temperature,

high-pressure environment to rapidly cook and expand the materials, preserving their nutritional components while improving the pet's

digestibility and absorption. The machine has a simple and compact structure, is easy to operate and maintain, and can be used

immediately without complex installation. It consumes little energy during operation, conforming to energy-saving and environmental

protection principles, while also reducing waste emissions during production. Whether for small-scale daily production or batch processing,

it can efficiently complete the task. This equipment provides pet owners and small-to-medium-sized breeders with an economical and

convenient solution for making their own pet food, resulting in fresher and safer 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.
