What are the advantages and limitations of wet pet food pellet machines?

Core Advantages: Extruder Enables Quality Upgrades

The low-temperature process of the wet dog food making machine maximizes the retention of pet food nutrients, with vitamin and amino acid retention rates 15%-25% higher than dry-processing equipment. It also enhances palatability, increasing pets' feed intake by over 30%. The high moisture content eliminates the need for additional watering, making it suitable for pets with sensitive digestive systems. The equipment has low energy consumption, and low-temperature operation reduces production costs. Furthermore, the extruder is easy to operate, requiring no specialized skills for setup and adjustment.

Potential Limitations: Requires Specific Addresses

The high moisture content of the finished product necessitates strict storage requirements, including vacuum filling and low-temperature refrigeration. Otherwise, spoilage is likely, increasing packaging and storage costs. The high moisture content of the wet dog food pellet machine places significant pressure on equipment sealing and corrosion prevention. Long-term use requires regular replacement of seals and cleaning of extruder residues, resulting in higher maintenance costs than dry-processing equipment. The single-line capacity is lower than dry-processing equipment, necessitating multiple lines in parallel for large-scale production, leading to higher initial equipment investment.

Extruder Optimization: Enhancing Equipment Competitiveness

To address maintenance issues, a food-grade stainless steel wet pet food extruder machine is selected, equipped with an automatic cleaning system to reduce manual cleaning costs. Regarding capacity, the extruder screw structure is optimized to improve feeding and extrusion efficiency; medium-sized extruders can achieve an hourly output of over 2000 kg. For nutrient retention, a precise temperature control module is equipped to control temperature fluctuations within ±2℃, further improving the retention rate of heat-sensitive nutrients and maximizing the equipment's advantages.
