Product Description

Liquid Nitrogen Tunnel Quick Freezer

The Liquid Nitrogen Tunnel Quick Freezer is designed to freeze food at an extremely fast rate, achieving temperatures as low as -190°C. With a cooling rate of ≥20°C/min, this machine is about 30 times faster than traditional compressor-based freezers, allowing food to pass quickly through the critical ice crystal growth zone (from 0°C to -5°C). This prevents damage to cell walls and reduces juice loss, preserving the flavor, texture, and nutritional value of the food.

Main Structure and Configuration:

Mesh Belt Tunnel: Continuous production line that ensures safety, durability, and ease of operation.
Body & Structure Material: Made from SUS304 Stainless Steel for long-lasting performance.
