A leading Indonesian sardine processing factory supplying major global retailers under private-label agreements.
The client faced mounting pressure to reduce production costs while simultaneously improving product consistency and extending shelf life for international export. Their existing sterilization line suffered from uneven heat distribution, resulting in:
High variance in texture quality (15% of batches showing mushy sardines)
Energy consumption 40% above industry benchmarks
Limited flexibility in can size formats
Frequent manual adjustments causing production delays
Solution: ZLPH MACHINERY’s Integrated Retort System
After thorough analysis, we installed a complete processing line featuring:
ZLPH High-Efficiency Retort Autoclave
Our flagship autoclave retort sterilizer employs dynamic pressure modulation specifically calibrated for oily fish products. The system’s multi-zone temperature control eliminated cold spots that previously caused inconsistent sterilization.
Automated Can Handling System
The integrated retort canning machine synchronizes with the retort packaging machine to maintain precise headspace control during filling and sealing—critical for maintaining sardine integrity during thermal processing.
Intelligent Process Management
The central retort machine control system automatically adjusts sterilization parameters based on real-time oil content analysis and can size detection, ensuring optimal F-value achievement without over-processing.
Implementation & Results:
Within 90 days of installation, the client achieved measurable improvements:
Energy consumption decreased by 38% through heat-recovery technology in the retort autoclave
Water usage reduced by 52% via closed-loop cooling system
Labor costs lowered by 60% through fully automated operation
Product loss from over-processing eliminated entirely
Texture consistency improved to 99.3% compliance rate
Omega-3 fatty acid retention increased from 78% to 94%
Shelf life extended from 18 to 36 months
Zero microbiological incidents across 500+ production batches
OEM Partnership Benefits:
As the client’s designated OEM partner, ZLPH MACHINERY provided:
Customized retort packaging machine configurations for their specific can dimensions
On-site technician training and 24/7 remote monitoring
Quarterly performance optimization reports
Spare parts inventory management program
Technical Superiority Demonstrated:
The autoclave retort sterilizer consistently maintained temperature uniformity within ±0.7°C, far exceeding the industry standard of ±2.5°C. This precision, combined with the reliability of our retort canning machine interface, enabled the client to expand production capacity by 45% without additional floor space.
“ZLPH’s retort machine system didn’t just upgrade our equipment—it transformed our business model. We’ve reduced operational costs by $2.8 million annually while securing contracts with three new European retailers who specifically praised our product consistency. Their OEM partnership approach ensured seamless integration with our existing infrastructure.”
