Zhucheng Qiangda Food Machinery Factory Unveils Advanced Industrial Freezing Systems: Driving Standardization in Food Preservation

ZHUCHENG, China – April 29, 2026 – Zhucheng Qiangda Food Machinery Factory has officially announced the launch of its comprehensive suite of industrial-grade freezing solutions, featuring three core systems: Tunnel, Fluidized, and Spiral freezers. As the global food sector pivots toward high-efficiency and intelligent automation, Zhucheng Qiangda Food Machinery Factory is addressing critical industry pain points—such as excessive footprint, high energy consumption, and inconsistent product quality—by mastering the thermodynamics of the "Maximum Ice Crystal Formation Zone."

Tunnel Freezers: High-Throughput Processing for Continuous Production

The Tunnel Freezer serves as the flagship solution from Zhucheng Qiangda Food Machinery Factory for large-scale, linear production lines. Engineered to move products through an ultra-low temperature zone of -35°C or below, the system utilizes rapid-freeze technology to bring the product’s core temperature to -18°C within minutes. This rapid transition prevents the formation of large ice crystals, preserving the cellular integrity of the food and eliminating the texture degradation commonly found in traditional slow-freezing methods.

• Optimized Airflow Engineering: The Tunnel Freezer utilizes high-velocity airflow (3-12 m/s) to break the stagnant air boundary layer surrounding the product. This maximizes heat exchange efficiency, effectively "locking in" natural color, nutrients, and moisture while minimizing drip loss.

• Versatile Conveyor Adaptability: Zhucheng Qiangda Food Machinery Factory offers customizable conveyor options based on specific product characteristics. Stainless steel mesh belts are standard for seafood and meat processing, while solid steel belts are optimized for high-viscosity items like pasta and ice cream.

• Thermal Efficiency & Intelligence: The QSD Series utilizes high-density polyurethane (PU) insulation panels and a PLC-based intelligent control system. This synergy ensures real-time monitoring of operational parameters, delivering superior energy-to-output ratios even under heavy load conditions.

  
  

Fluidized Bed Freezers: Solving Inter-Product Adhesion in IQF

The Fluidized Bed Freezer is a specialized IQF (Individual Quick Freezing) solution developed by Zhucheng Qiangda Food Machinery Factory specifically for small-particle products such as diced fruits, vegetables, and shrimp. By utilizing vertical high-pressure airflow, the system suspends the product in a "fluidized" state, ensuring 360-degree exposure to frigid air.

• Anti-Caking Technology: A integrated variable-frequency mechanical vibration system works in tandem with a two-stage conveyor process—crust-freezing the surface in the first stage and deep-freezing the core in the second—to ensure individual particles remain separate and free-flowing.

• Hygiene-Centric Structural Design: Zhucheng Qiangda Food Machinery Factory has engineered the internal chamber with a 1.4° slope and integrated SUS304 stainless steel flooring. This design ensures rapid drainage during defrosting and cleaning cycles, meeting the rigorous sanitation requirements of HACCP standards.

• High-Capacity Refrigeration Power: Models such as the TF500A provide stable, high-output cooling capacity, designed to handle the peak processing demands of seasonal harvests without performance fluctuations.

  
  

Spiral Freezers: Spatial Optimization and Delicate Handling

The Spiral Freezer represents the intersection of spatial engineering and advanced refrigeration at Zhucheng Qiangda Food Machinery Factory. Unlike horizontal tunnels, the spiral configuration extends the freezing path vertically, allowing for a significantly higher production capacity per square meter of floor space.

• Footprint Rationalization: This vertical multi-tier design allows processors with limited floor space to double their output, effectively converting overhead volume into tangible production revenue.

• Gentle Handling of High-Value Goods: The smooth spiral drive mechanism minimizes physical impact and mechanical stress, which is vital for preserving the structural integrity of fragile items such as strawberries, blueberries, and breaded prepared meals.

• Intuitive Human-Machine Interface (HMI): The integrated PLC touchscreen console features self-diagnostics and one-touch recipe switching, allowing operators to calibrate freezing times—from 10 minutes to several hours—with precision.
