While tunnel freezers have their place in food processing, they do have some limitations:
- Space requirements: Typically require more horizontal space than spiral freezers
- Limited capacity: May have lower throughput compared to spiral systems in the same footprint
- Product handling: Can be less flexible with product sizes and shapes
- Energy efficiency: May be less efficient in terms of air circulation and energy use
- Freezing time: Limited by the length of the tunnel, which can be a constraint for some products
For factory managers considering freezing solutions, these factors should be weighed against the specific needs of their production lines and available space.
