For industrial pet food manufacturers, production capacity is one of the most important factors.
SUNYI can configure the machine according to the required output and actual tray format rather than simply providing a theoretical maximum speed.
160–180 trays/minute
The final guaranteed production output should be determined after testing the actual:
Aluminum tray samples
Aluminum lid samples
Wet pet food product
Filling weight
Product viscosity
Particle/chunk characteristics
Tray and lid dimensions
This approach ensures that the selected configuration is suitable for real continuous production, rather than only achieving a nominal machine speed under ideal conditions.
The machine can be engineered to accommodate multiple aluminum tray formats, helping pet food manufacturers produce different retail pack sizes on the same production line.
Filling Weight | Tray A | Tray B | Tray C | Tray Height | Volume | Tray Type | Aluminum Lid |
|---|---|---|---|---|---|---|---|
85 g | 79.4 mm | 90.0 mm | 86.4 mm | 21.7 mm | 109 ml | Ribbed | 86.2 × 86.2 mm |
100 g | 77.5 mm | 88.0 mm | 85.0 mm | 24.0 mm | 115 ml | Ribbed | 84.8 × 84.8 mm |
150 g | 77.5 mm | 88.0 mm | 85.0 mm | 32.4 mm | 162 ml | Ribbed | 84.8 × 84.8 mm |
300 g | 102.5 mm | 114.0 mm | 110.4 mm | 39.0 mm | 324 ml | Ribbed | 110.0 × 110.0 mm |
Note: Final machine configuration and format compatibility should be confirmed using actual tray and lid samples before engineering.
Wet pet food can vary significantly in viscosity, density and particle size. Some products are smooth and homogeneous, while others contain visible pieces of meat, vegetables or other ingredients.
SUNYI can configure the filling system according to the characteristics of the product.
Wet cat food
Wet dog food
Meat-based pet food
Chunky pet food
Gravy-based pet food
Semi-viscous pet food
Pet food containing solid pieces
Other portioned wet pet food products
The filling system can be customized according to:
Product viscosity + filling weight + particle size + production speed + required filling accuracy
For wet pet food containing solid pieces or chunks, the filling system needs to maintain stable product flow while preventing excessive product damage or filling blockage.
SUNYI can evaluate and configure the filling system based on the actual product characteristics.
Key factors include:
Maximum particle/chunk size
Product viscosity
Chunk-to-sauce ratio
Product temperature
Filling weight
Required filling accuracy
Target production speed
For products with larger solid particles, the filling system can be specially designed to provide smoother product transfer and more stable portioning.
The maximum particle size should be confirmed through product testing before final machine configuration.
Wet pet food packaged in aluminum trays may undergo subsequent retort or sterilization processes.
Therefore, the sealing system must provide reliable package integrity before the trays enter the sterilization process.
SUNYI can evaluate the complete packaging process based on:
Aluminum tray specifications
Aluminum lid specifications
Sealing material
Product characteristics
Retort temperature
Retort pressure
Sterilization process
Required shelf life
Final retort suitability should be verified through sample testing and sealing validation with the customer's actual packaging materials and sterilization process.
The machine can be configured for multiple aluminum tray formats to support flexible production.
Format changeover may involve adjustment or replacement of:
Tray denesting tooling
Filling tooling
Product-contact components
Lid feeding components
Sealing tooling
Guides and positioning components
The final changeover procedure and estimated changeover time depend on the number of formats and the selected machine configuration.
The machine is designed with hygiene and easy cleaning in mind.
Product-contact components can be manufactured using suitable food-grade stainless steel materials, such as SUS304, with higher-grade materials available for specific applications where required.
The machine can be configured with:
Smooth product-contact surfaces
Easy-access cleaning areas
Removable product-contact components
Hygienic machine structure
Easy maintenance access
Optional cleaning solutions according to application requirements
Cleaning and CIP requirements should be evaluated according to the actual wet pet food formulation and production process.
The aluminum tray filling and sealing machine can be integrated into an automated pet food packaging line.
