The IQF Tunnel Freezer For Diced Onion Vegetable is a high-efficiency freezing solution specially designed for processing diced onion in large-scale vegetable processing plants. Due to the high moisture content, strong pungent aroma, and delicate cellular structure of diced onion, conventional freezing methods often cause clumping, dehydration, or texture damage.
This IQF (Individually Quick Frozen) tunnel freezer is engineered to rapidly freeze each diced onion piece separately, preserving its natural color, flavor, texture, and nutritional value while preventing adhesion between particles. It is ideal for frozen vegetable factories, food processing companies, central kitchens, and export-oriented enterprises.
Diced Onion IQF Freezer Working Principle
Diced onion pieces are small, lightweight, and prone to sticking together due to surface moisture. To achieve true individual quick freezing, the machine uses a powerful cold air circulation system combined with a mesh belt conveyor.
-
Uniform Feeding System
Evenly distributed diced onion enters the tunnel through a vibration or spreading device to avoid overlapping. -
High-Velocity Cold Air Circulation
Strong cold airflow passes through and around the diced onion layer from top and bottom, ensuring rapid and uniform heat exchange. -
Instant Individual Freezing
Within a short time, the surface moisture crystallizes quickly, forming a protective frozen layer that prevents pieces from sticking together. -
Continuous Discharge
Fully frozen diced onion exits the tunnel individually, ready for automatic weighing and packaging.
The entire process ensures fast freezing speed, minimal cell damage, and excellent product quality.
Onion Cube IQF Tunnel Freezer Advantages
