**❄️ Blast Freezer Guide: Types, Price & Applications**

A **blast freezer** is a specialized freezing system designed to rapidly reduce the temperature of products, typically bringing the core temperature down to **-18°C or below within a short time**. Compared to traditional freezing, blast freezing minimizes ice crystal formation, preserving product texture, moisture, and nutritional value.

## ⚡ What is a Blast Freezer

A **blast freezer** operates at extremely low temperatures, typically:

- Freezing temperature: **-35°C to -40°C**
- Final storage temperature: **-18°C**

👉 Key advantage:
- Rapid freezing prevents large ice crystals  
- Maintains original structure and quality

👉 Example:
Fresh meat can be cooled from **+37°C to -18°C within 30 minutes**, significantly improving product quality.
