Project Overview

This project aims to build a modern facility integrating Quick Freezing and Ultra-Low Temperature Storage functions. Its core mission is to use rapid freezing technology to bring the product's core temperature through the maximum ice crystal formation zone in the shortest possible time, thereby perfectly preserving the product's texture, nutrition, and quality. It serves as a core quality assurance for premium seafood, prepared meals, fruits, and vegetables.

Core Technology

  1. High-Efficiency Quick Freezing Zone: Utilizes Spiral/Tunnel Freezers (IQF) or Blast Freezing Rooms to achieve Individual Quick Freezing of products.


  2. Ultra-Low Temperature Storage Zone: Equipped with freezer storage at -25°C or below for the long-term stable storage of quick-frozen products.


  3. Intelligent Logistics: Designs seamlessly connected logistics channels to achieve an uninterrupted cold chain process from freezing to storage, eliminating temperature fluctuations.

Challenges

  1. Rapid Cooling & Energy Consumption Control.
  2.  Freezing Uniformity & Quality Assurance. 
  3. Ice Crystal Damage & “Freezer Burn”.
  4. Automation & Efficiency Bottlenecks.
  5. Complex Defrosting & Maintenance.

Challenges

  1. ①Use high-efficiency inverter compressors and EC fans to ensure cooling power while improving the Energy Efficiency Ratio.②Implement heat recovery technology to reuse waste heat from the freezing process for defrosting or domestic hot water, achieving cascading energy use.

  2. ①Optimize airflow organization within the freezing equipment through Computational Fluid Dynamics (CFD) simulation to ensure uniform air velocity and temperature distribution.②Customize specific racks and stacking patterns for different products to minimize airflow dead zones.

  3. ①Core technology is “SPEED”: Ensure rapid passage through the maximum ice crystal formation zone by powerful refrigeration and precise temperature control, forming tiny ice crystals to minimize cell damage.②Maintain high relative humidity in storage and use Modified Atmosphere Packaging (MAP) to effectively suppress moisture sublimation and freezer burn.

  4. ①Integrate automated conveyor systems at both ends to enable continuous production.②Design buffer zones and rapid-opening doors to minimize thermal exchange and maintain the low-temperature environment.

  5. ①Adopt intelligent timed or on-demand defrost strategies to perform efficient electric or hot gas defrosting during low-load periods.②Select high-efficiency hydrophilic fin evaporators to delay frost formation and facilitate rapid drainage of meltwater.
