The entire line is highly automated and flexibly configured. It can also be compatible with extruded products such as aquatic feed and pet feed, making it an ideal choice for the upgrading of the pet food industryI. Market Background: Pet Food Is Moving Toward Refinement and FunctionalitIn recent years, pet food consumption has continued to upgrade. Consumers' requirements for pet food are increasingly close to those for human food-not only focusing on nutritional indicators such as protein, fat, and vitamins, but also paying attention to product shape, taste, color, and digestibility. Pet food generally consists of meat, meat by-products, grains, vitamins, and minerals. Grains such as soybean meal, corn meal, cracked wheat, and barley are often used to improve product consistency. How to scientifically proportion these raw materials and process them into safe, nutritious, and highly palatable products has become the core concern of pet food manufacturersAt the same time, subcategories such as pet staple food, snacks, and functional food are growing rapidly, and the market has placed higher requirements on the stability, flexibility, and hygiene standards of production equipment. Traditional single-screw equipment is gradually showing limitations in output, mixing uniformity, and raw material adaptability, while twin-screw extrusion technology, with its excellent cooking, shaping, and nutrient retention capabilities, is becoming the mainstream process in pet food processing. Shandong Forward Machinery Co., Ltd. closely follows market trends, and its pet food production line is an efficient solution for this demand.

II. Production Line Composition and Process Flow

The Shandong Forward pet food production line consists of a mixer, screw conveyor, pre-conditioner, twin-screw extruder, air conveyor, multi-layer dryer, automatic flavoring line, cooling conveyor, and other equipment, forming a continuous, automated production line. The entire line is made of stainless steel, meeting food hygiene requirements. Key components are wear-resistant treated to ensure long-term stable operationThe process flow is as follows:

1. Raw Material Mixing

Dry raw materials are first crushed, then fully mixed with wet raw materials in the mixer to ensure even distribution of various nutrients. The mixer is equipped with dual-shaft mixing paddles inside, offering fast mixing speed and high uniformity. Water, oil, and other liquids can be added according to the formula, providing homogeneous materials for subsequent extrusion.

2. Pre-conditioningThe mixed materials enter the pre-conditioner, where steam is introduced for pre-cooking. This step can increase the gelatinization degree of the materials, soften the raw materials, reduce the load inside the extruder, kill some bacteria, and improve product digestibility

3. ExtrusionThe pre-conditioned materials enter the twin-screw extruder, where they are further cooked under high temperature, high pressure, and high shear, and are shaped through the die and rotary cutter. The twin-screw extruder has excellent self-cleaning performance and mixing efficiency. The screw is made of alloy material and undergoes nitriding treatment, offering high strength and good wear resistance. The barrel temperature can be controlled in zones to suit different formula requirements.

4. Air Conveying and Drying

The formed pet food is conveyed by the air conveyor into a multi-layer dryer or belt dryer. Under hot air circulation, the moisture is gradually reduced so that the product meets safe storage standards. Drying temperature and time can be precisely adjusted to ensure uniform moisture inside and outside the pellets and a crispy texture.

5. Flavoring and CoolingThe dried product enters the automatic flavoring line, where animal fat, vitamins, minerals, and other nutrients are sprayed through a drum to achieve nutritional fortification and flavor blending. It is then cooled by the cooling conveyor, finally producing crispy, nutritious pet food

6. PackagingQualified products can enter the automatic weighing and packaging machine for measuring, filling, and sealing, forming commercial packaging and improving production efficiency and product image.

III. Diverse Shapes: Flexible Switching of Dies and Rotary Cutting Technology

A major highlight of this production line is the rich variety of product shapes. By changing extrusion dies of different shapes and adjusting the variable frequency speed control parameters of the rotary cutting system, it can produce pet food in various shapes such as bone, round, star, ring, stick, triangle, heart, dual-color, and filled shapes. The rotary cutting system has strong power, stable operation, neat cuts, and uniform shapes. It can not only satisfy pets' curiosity about food appearance, but also help pet food enterprises create differentiated products and enhance market competitivenessIn addition, by adjusting dies and processes, pellets of different densities and sizes can be produced to suit the feeding habits of different pets such as puppies, adult dogs, cats, and ornamental fish. Dual-color and filled products can be achieved through co-extrusion technology, with different formulas for the outer and inner layers, making them both attractive and nutritious

IV. Nutritional Formulation: Scientific Formula and Uniform Mixing

The nutritional formulation of pet food directly affects the healthy growth of pets. The Forward pet food production line starts with the raw material mixing stage and is equipped with an efficient mixer to ensure uniform mixing of dry and wet materials and trace ingredients. The twin-screw extruder uses an alloy screw with nitriding treatment, offering high strength and good wear resistance. It can cook materials under mild conditions, reduce nutrient loss, and improve digestibility. In the flavoring stage, animal fat, vitamins, minerals, etc. can also be added according to the formula to achieve nutritional fortification and meet the nutritional needs of different dog breeds and pets at different growth stagesThe extrusion process is a high-temperature, short-time process. It can effectively passivate anti-nutritional factors, improve protein digestibility, and retain most heat-sensitive nutrients. Through pre-conditioning and precise temperature control, product density, hardness, and crispness can be flexibly adjusted, providing broad space for formula design

V. Equipment Features and Advantages

High degree of automation: From feeding to finished product, the process is completed continuously, with simple operation and reduced manual intervention. The entire line adopts PLC central control and touch screen operation, with intuitive parameter setting and real-time monitoring of operating statusStable and reliable operation: The main power system and rotary cutting system both adopt variable frequency speed control, with strong power, high efficiency, and energy saving. The automatic lubrication and forced cooling system ensure safe operation of the equipment and extend service lifeFlexible configuration: According to customer capacity requirements, models such as DSE65-III, DSE70-II, and DSE85-II can be selected, with production capacities covering 120-150 kg/h, 200-250 kg/h, and 400-500 kg/h. Layout design can also be carried out according to site conditionsMulti-purpose: By adjusting dies and processes, it can also produce extruded products such as aquatic feed and textured protein, improving equipment utilization and reducing investment riskHygienic and easy to clean: Parts in contact with materials are made of stainless steel, and the structural design is easy to disassemble and clean, meeting food-grade production requirements
