Automatic Steamed Pet Food Production Line
Automatic Steamed Pet Food Production Line
Product Overview
The automatic steamed pet food production line is a professional low-temperature processing system independently developed by LongerFM for high-end steamed pet staple food and soft meat treats.
Different from traditional high-temperature boiling and extrusion technology, this automatic steamed pet food production line adopts constant-temperature low-temperature steaming technology to lock meat freshness, retain natural nutrients, and produce ultra-soft, easily digestible pet food.
It is especially suitable for mass production of low-allergen staple food for kittens, puppies, and senior pets.
The entire automatic steamed pet food production line takes frozen meat as the main raw material and realizes fully automatic one-stop operation, including frozen meat unpacking and feeding, mechanical lifting and conveying, frozen meat fine grinding, precise batching and mixing, intelligent extrusion molding, constant-temperature steam cooking, uniform cooling and cutting, automatic packaging, pasteurization and finished product delivery.
With compact workflow and stable molding effect, the automatic steamed pet food production line has become the core mass-production solution for high-value functional steamed wet pet food.
Standard Production Process
Frozen meat unpacking & feeding → Chain plate lifting conveyor → Frozen meat grinding → Vacuum mixing & seasoning → Intelligent extrusion molding → Constant-temperature steam steaming tunnel → Air cooling system → Automatic granule cutting → Automatic packaging → Pasteurization sterilization → Cooling & air drying → Finished product inspection & delivery
1. Raw Material Preprocessing Section
Whole frozen meat blocks can be directly processed without pre-thawing, saving workshop space and energy consumption. The frozen meat grinder finely crushes meat and bone materials with adjustable particle fineness to produce delicate meat paste or textured meat particles according to different product formulas. Fully enclosed conveying effectively reduces material oxidation and peculiar smell.
2. Vacuum Mixing & Homogenization Section
Equipped with a negative-pressure vacuum mixer to eliminate air bubbles inside the meat paste. Meat materials, grains, fruit and vegetable powder, nutritional additives and flavor enhancers are fully homogenized without stratification or water separation. The process perfectly retains meat juice and natural flavor, greatly improving food palatability for pets.
3. Intelligent Molding Section
Adopts water-cooled extrusion molding host to avoid high-temperature damage to heat-sensitive nutrients. Multiple replaceable molds support customized shapes such as round particles, strips, and heart-shaped steamed meat treats. The molding density and softness can be precisely adjusted to produce soft and non-hard particles suitable for young and elderly pets.
4. Constant-temperature Steam Cooking Section (Core Technology)
The closed steam tunnel stably maintains a low temperature of 60–80°C for gentle steaming. Bidirectional circulating steam ensures uniform heating without raw cores or dry surfaces. The PLC intelligent system precisely controls steaming time and temperature to adapt to various formulas, achieving thorough maturation without aging the meat texture.
5. Cooling & Cutting Section
After steaming, the products are quickly cooled through an air cooling tunnel to stabilize texture and hardness. The servo automatic cutting machine performs fixed-length cutting with high precision, ensuring uniform particle size, fewer broken scraps and excellent finished product appearance.
6. Packaging & Sterilization Section
The production line supports multiple packaging types including fresh pouches, stand-up pouches and trays. Servo quantitative filling achieves ±1g high precision with multi-layer heat sealing to prevent leakage. Custom pasteurization curves ensure thorough sterilization while maintaining the soft and tender taste of steamed meat, effectively extending shelf life without excessive preservatives.
7. Finished Product Inspection Section
Integrated metal detector and weight checking equipment automatically reject defective products with insufficient weight, broken seals or foreign impurities, ensuring 100% qualified finished products for warehouse delivery.
Material Standard & Configuration
All parts directly in contact with food, including hoppers, grinding blades, mixing paddles, molds and conveyor belts, adopt food-grade SUS304 stainless steel, fully complying with FDA and HACCP international food safety standards.
The equipment frame uses high-quality 201 stainless steel to balance cost and structural stability. All detachable structures allow high-pressure water cleaning with no sanitary dead corners, convenient for daily cleaning and factory audit inspection.
Equipped with a bilingual PLC intelligent control cabinet, storing more than 100 sets of production formulas for one-key switching of different products. Voltage and frequency can be customized to adapt to global power standards such as 220V/60Hz, 415V/50Hz and 440V/60Hz.
Modular optional capacities: 300kg/h, 800kg/h, 1500kg/h, 2500kg/h, 3500kg/h. Custom compact layout solutions are available for small and medium-sized workshops.
Core Advantages
1. Low-temperature Steaming Technology for High Nutrient Retention
Different from traditional high-temperature processing, low-temperature constant steaming retains complete meat protein, amino acids and natural meat flavor. The finished products are tender, ultra-soft and easy to digest, solving common problems such as hard texture, poor appetite and gastrointestinal burden for young, old and sensitive pets.
2. Multi-product Flexible Production
By simply replacing molds and adjusting process parameters, the line can produce steamed staple food particles, soft meat strips and functional nutritional snacks. It supports multiple packaging formats, enabling one line to cover multiple SKUs and greatly reducing factory investment costs.
3. High Automation & Labor Saving
The whole line realizes closed automatic circulation from raw material feeding to finished product output. Only 2–3 workers are required for operation, greatly reducing manual handling, sorting and packaging costs.
4. Energy-saving & Stable Continuous Operation
Equipped with steam waste heat recovery system, reducing steam energy consumption by about 30%. International brand core electrical components and reinforced frame support 24-hour uninterrupted industrial production. Sufficient spare parts inventory ensures long-term stable operation.
5. Complete Turnkey Service
Full material test run and factory shooting videos are provided before delivery. Free CAD workshop layout drawings and water, electricity and steam layout solutions are supported. Professional engineers provide remote installation guidance and technical training. On-site overseas installation services are available for large orders.
Application Scenarios
Suitable for large pet food factories, OEM processing workshops and high-end functional pet food production bases, this automatic steamed pet food production line is ideal for producing low-allergen steamed pet staple food, soft steamed meat snacks and intestinal conditioning pet food. The line can be expanded with enzymatic hydrolysis tanks and bone mud machines to produce high-nutrition functional pet food.
After-sales Support
1. One-year full warranty covering motors, PLC control system and all core components.
2. Complete English operation manuals and fault-tutorial videos for equipment maintenance.
3. 7×24-hour online multilingual technical support for debugging and problem solving.
4. Long-term factory-price supply of original spare parts to ensure stable production.
