Continuous Freezing Machine for Dumplings

Single Spiral Freezer

Double Spiral Freezer

Key Advantages

• Tailored Capacity & Vertical Optimization
  Employs a fully automated continuous spiral freezing design. Soup dumplings move at a constant speed on a food-grade stainless steel mesh belt, spiraling upward or downward, making full use of vertical space to achieve the perfect balance of small footprint and large freezing capacity. Equipped with a variable frequency speed control system for stepless adjustment of conveyor speed according to product specifications and process requirements. Freezing capacity ranges from 500kg/h to 10,000kg/h, with custom design and manufacturing available based on client requirements.

• Ultra-Compact, Continuous Flow Design
  

  Utilizes optimized longitudinal counterflow air circulation and curved air duct design to create a uniform, powerful vertical airflow field within the spiral tower. Cold air envelops each soup dumpling, rapidly forming a frozen crust on the surface for setting, effectively preventing dough sticking while avoiding cracking caused by overly rapid freezing. This vertical airflow mode ensures uniform temperature distribution with no dead zones, short freezing time, low dehydration loss, and minimal juice loss upon thawing, resulting in excellent texture and taste.

• Precise & Uniform Hardening for Superior Quality
  Engineered with multi-zone temperature control and uniform high-velocity airflow, it ensures every product—from the center to the surface—experiences a consistent and optimal freezing curve. This rapid and uniform heat extraction minimizes ice crystal size, resulting in a smoother, creamier texture, and prevents shrinkage or deformation, guaranteeing consumer satisfaction and brand integrity.

• High Hygiene & Easy Maintenance  
  Integrates a PLC touch-screen control system for precise setting and real-time monitoring of temperature, air velocity, and conveyor speed in each freezing zone. Equipped with variable frequency fans for automatic airflow adjustment based on product load, achieving optimal freezing results with minimal energy consumption. Optional ADF air defrost system uses powerful airflow to remove frost from evaporators, extending processing time and improving equipment utilization.
