Vertical Plate Freezer vs. Tunnel Freezer: Which One is Right for You?

When it comes to industrial freezing, choosing the right equipment can directly impact product quality, production efficiency, and operational costs. Two of the most common options are the Vertical Plate Freezer and the Tunnel Freezer. Both serve important roles in the frozen food industry—but they work in very different ways.

So, which one is right for your business? Let’s take a closer look.

Vertical Plate Freezer: Compact and Efficient Block Freezing

How a Vertical Plate Freezer works:

Products are loaded into vertical pockets between parallel plates. A hydraulic system presses the plates tightly against the product, allowing direct contact freezing.

Vertical Plate Freezer Key Benefits:

• Fast & uniform freezing through direct contact with plates.

• Compact footprint – requires less floor space.

• Dense, solid frozen blocks – ideal for stacking, storage, and transportation.

• Energy-efficient.

• Perfect for for fish, shrimp, meat and other block products.

Best for:

Seafood and meat processors, especially those exporting products in frozen blocks for long-distance transport.

Tunnel Freezer: Continuous High-Capacity IQF Freezing

How a Tunnel Freezer works:

Products are placed on a conveyor belt and moved through a tunnel. This creates an IQF (Individually Quick Frozen) result.

Tunnel Freezer Key Benefits:

Continuous production – suitable for high-volume operations.

IQF capability – keeps products separate (perfect for shrimp, fish, meat, baked product etc.).

Flexible product handling – can be customized according to customer needs.

Best for:

Food processors that need large-scale continuous freezing for products such as seafood, meat, vegetables, bread and prepared foods.

Side-by-Side Comparison

Comparison Item	Vertical Plate Freezer	Tunnel Freezer
Freezing Method	Direct contact between plates	Cold air circulation
Product Form	Solid frozen blocks	Individually Quick Frozen (IQF)
Production Mode	Batch processing	Continuous processing
Footprint	Compact, space-saving	Larger floor space required
Best For	Fish, shrimp, meat and other block products	Seafood, ready meals, meat and baked product etc.

Which One Should You Choose?

If your business focuses on exporting seafood or meat in block form, a Vertical Plate Freezer is the most efficient solution.

If you need continuous freezing of IQF products at high capacity, a Tunnel Freezer will be the better choice.

In some cases, companies even use both systems to handle different product lines.
