Flow Chart

Dry Pet Food Extrusion Line

How is pet food produced?

Typical raw materials used in pet food processing include grain meal, vegetable proteins, minerals and vitamins, and in some cases meat or fish meal and fresh meat. The dry material enters the preconditioner+ and undergoes steam hydration. The blender mixes the ingredients and ensures that the steam, moisture and ingredients are mixed properly. Pretreatment produces partial gelatinization of the starch and structure of the polymer. The parboiled mixture is then fed to a twin-screw extruder where shear, internal temperature, pressure, moisture and residence time are precisely controlled to achieve optimal starch gelatinization without loss of food quality. At different processing stages, liquid or steam can be injected through ports in the extruder barrel. Vent packing can be used for degassing at this stage.

Pet food production line production process

1. Mix

The mixing process is a key process in pet food production. The basic process is to weigh raw materials of different weights according to the formula, then pour them into the crusher for crushing, and then temporarily store all the raw materials in the storage silo. Then all the ingredients are ready and blended in a blender.

2. squeeze

Extrusion is a high-temperature, short-time heat treatment process. It not only reduces the degradation of food nutrients and improves protein and starch digestibility, but also destroys anti-nutrients and microorganisms. Dry pet food in round, triangular, flower-shaped, bone-shaped and other shapes can be produced through different molds (templates) of the feed extruder. In pet food production, fat is often added to improve the palatability of the pet food, which is done during the conditioning process. Additionally, in order to give pet food tablets different colors, manufacturers often add pigmented water to the extrusion chamber.

3. Dry

The drying part is mainly used to remove moisture from puffed pet food. The extruded material has a soft texture and a moisture content of 20-30%. After drying, the moisture of the finished product is controlled at 8%~10%, which can ensure the storage of the materials within a certain period of time.

4. Add grease

Oil is the best source of energy, so 2%-40% oil can be added to the formula according to the pet's growth needs. We recommend that the fat content in the formula, i.e. the total oil content in the extruder, should be kept within 12%. If the oil content is required to exceed 12%, the hardness of the particles will be significantly reduced. If the extruded material needs to contain more than 12% oil, it is recommended to add oil after drying. Can be used under normal pressure or vacuum spraying, depending on the amount of oil added. Exterior spray will give the pet food tablets a more attractive appearance. In addition to oil, some powdered attractants are also sprayed to increase the palatability of pet feed.

5. Cooling and screening

The main function of the cooling section is to cool the dried materials from high temperature to near room temperature and take away part of the moisture. Additionally, substandard food tablets will be separated from qualified food products during this process.

Main Equipment List

I. Flour Mixer or Ribbon Mixer

The raw materials, such as grains, proteins, vitamins, and minerals, are combined and mixed evenly in a mixing machine to create a homogenous blend.

II. Screw Conveyor or Scraper Conveyor

The mixed materials are transferred to the extruder using a conveyor, such as a screw conveyor or a Scraper Conveyor

Dry Pet Food Extrusion Line

III. Double Screw Extruder

The core component of the production line, the extruder processes the mixed materials by applying heat, pressure, and mechanical shearing. This causes the materials to undergo various physicochemical changes, resulting in the formation of a dough-like mass. The extruder then pushes this mass through a die, creating the desired shape and size of the pet food.

IV. Vibrating Sifter

Vibrating Sifter is a conveyor. It uses to convey the raw material to next equipment, and at the same time, it sifts to prevent the raw materials sticking together.

V. Air Conveyor

Air Conveyor is responsible to convey the materials to the next equipment. There equipped with a blower to blow the materials.

VII. Flavoring Machine

To enhance the palatability of the pet food, a flavoring system can be employed. This may involve spraying liquid flavors, oils, or powders onto the cooled pet food to make it more appealing to pets.

Advantages of Pet Food Production Line

1. Precise control of process parameters and automation ensure optimized pellet quality: gelatinization, expansion, consistent texture and quality. These quality standards are achieved because the screw ensures uniform processing and positive pumping. The processing of viscous pastes does not depend on the friction between the screw and barrel. Embedded automatic temperature control and regulation system, modular screw configuration and screw speed are easily programmable to help improve production line performance.

2. Intelligent pet food extruder: formula management (recording, access, supervision), process management (start/stop), sensor installation, control and maintenance. Advanced production line automation helps reduce operating costs and promotes stable nominal production.

3. Use special molds for creative shapes and finishing of products with innovative shapes and different textures (co-extrusion).

4. The composition is flexible and various raw materials with high fat content can be processed as needed.

5. Use standard parts of extrusion and drying equipment to reduce maintenance and facilitate inspection of different machine parts.

6. Specifically designed by our expert engineers with advanced automation features to ensure precise process control for easily reproducible product quality.

7. From 100kg/hour to 2000kg/hour
