InnovaSter-Trade Launches HIDROSTER Compact

Continuous Sterilization for Mid-Sized Food Manufacturers

InnovaSter-Trade Ltd. announces the launch of HIDROSTER Compact, a continuous sterilization system engineered for mid-sized food production facilities.

Addressing a Market Need
Continuous sterilization technology delivers measurable advantages in high-volume production environments. These systems provide consistent heat treatment, efficient energy utilization, and higher throughput capacity. However, capital requirements have traditionally limited adoption to large-scale operations.
The food processing industry is predominantly composed of small and mid-sized enterprises. These operations prioritize operational flexibility, process different products on the same line, and require the ability to adapt quickly to varying product formulations. For these manufacturers, batch retort autoclaves serve effectively, providing the flexibility needed for diverse product portfolios and smaller production runs per SKU.

But as production volumes increase and new products are introduced, production lines need to be upgraded. Energy costs increase, labour costs increase, and the entire production life cycle of a product needs to be tracked. HIDROSTER Compact fills this gap.
This new development is the ideal solution for medium-sized plants.

Engineering for Scale and Investment Protection
HIDROSTER Compact represents a strategic approach to continuous sterilization system design. The platform addresses the transition point where food manufacturers move from batch processing to continuous operations. This transition typically occurs when production volumes reach levels where continuous processing economics become favorable, but full-scale industrial systems represent excessive capacity.
For small and mid-sized enterprises, minimizing initial capital expenditure remains a key investment criterion. HIDROSTER Compact is engineered to deliver professional-grade thermal processing performance while addressing both the capital constraints and the specific operational requirements of growing manufacturers.
Core specifications:
• Sterilization capacity from 250 to 500 cans per minute
• Compatible with metal cans, glass containers, and flexible packaging formats
• Sterilization temperatures to 132°C at 2.4 bar
• Full PLC automation with HMI touchscreen control
• Integrated compliance documentation and process validation
Proven Split Hydrostatic Technology
HIDROSTER Compact utilizes the split hydrostatic principle that forms the foundation of full-scale HIDROSTER installations. This Hungarian-engineered approach, developed in the 1960s, ensures uniform heat treatment as products move continuously through precisely controlled heating, sterilization, and cooling zones.
The core technology remains unchanged. "The split hydrostatic system, independent zone control, and energy recovery architecture are integral to the design. The system is optimized by focusing on essential functionality for mid-scale operations."
This delivers critical processing advantages:
• Uniform heat treatment across all packages
• Controlled residence time in each thermal zone
• Energy consumption reduction up to 40% compared to conventional systems
• Elimination of batch-to-batch process variation
• Continuous production flow
Strategic Capacity Scaling
The modular architecture addresses a fundamental challenge in food processing capital planning. Operations must balance current capacity requirements against future growth trajectories while managing capital allocation efficiently.
Equipment investment must align with operational reality. Manufacturers need appropriate capacity for current production volumes, with a clear path to scale when market demand justifies expansion.
The modular design enables:
• Initial capacity matched to current production requirements
• Capacity doubling through expansion module integration
• Minimal production disruption during system expansion
Processing Scale and Applications
HIDROSTER Compact is engineered for facilities producing 50,000 to 150,000 units per day. This represents the transition point where continuous processing economics become favorable.
Different processing methods serve different operational requirements:
Batch retort autoclaves provide flexibility for smaller production runs with high product variety. They remain the appropriate technology for many operations.
Continuous systems like HIDROSTER Compact address higher-volume requirements through:
• Consistent heat treatment for every processed unit
• Uninterrupted production flow
• Efficient energy utilization through steady-state operation
• High production volume with one compact equipment.

Comprehensive Process Control and Documentation
Modern food processing demands rigorous process validation and traceability. HIDROSTER Compact incorporates comprehensive PLC control with automated functionality that ensures compliance requirements are met systematically.
System capabilities include:
• Recipe management for multiple product specifications
• Real-time temperature and pressure monitoring across all zones
• Automated process data acquisition and logging
• F₀ value calculation and verification
• Audit-ready report generation in standard formats
• Energy consumption monitoring and analysis
• Secure remote access for authorized personnel

Product Application Range
HIDROSTER Compact processes diverse food categories in hermetically sealed packaging:
Vegetables: Corn, beans, peas, mushrooms, mixed vegetable preparations
Ready meals: Complete meal assemblies, prepared side dishes, heat-and-serve entrees
Protein products: Meat preparations, fish and seafood products, poultry items
Liquid products: Soups, sauces, gravies, liquid seasonings
Pet food: Wet pet food formulations in various package formats
Specialized applications: Baby food, dairy preparations, fruit-based products
The system accommodates multiple packaging formats including cans of various dimensions, glass jars and bottles, and flexible pouches. This flexibility supports product portfolio diversity without equipment limitations.

Established Technology Foundation
HIDROSTER Compact builds upon InnovaSter-Trade's three decades of continuous sterilization system manufacturing. HIDROSTER installations currently operate in production facilities throughout Hungary, France, Italy, Serbia, Poland, Turkey, Moldova, Ukraine, and Russia.
The split hydrostatic principle is proven across numerous installations. PLC control systems have extensive operational history.
