2 Unit Evaporators for Freezing Tunnel

2 Unit Evaporators for Freezing Tunnel

Working Principle

1. Heat Absorption:

• The evaporator removes heat from the air or the product passing through the freezing tunnel. As the refrigerant evaporates inside the coils, it absorbs heat, causing the air or product temperature to drop rapidly.

2. Refrigerant Cycle:

• The refrigerant, after absorbing heat and evaporating, is cycled back to the compressor. The compressor then compresses the refrigerant gas, raising its temperature and pressure before it moves to the condenser, where it releases heat and condenses back into a liquid.

3. Airflow Management:

• Fans are used to circulate cold air over the products in the freezing tunnel, ensuring even cooling and preventing ice formation on the evaporator coils.

Applications

• Food Processing: Rapid freezing of various food products such as fruits, vegetables, meats, and seafood to preserve quality and extend shelf life.

• Pharmaceuticals: Used in the freezing of certain pharmaceutical products and biological materials.

• Industrial Processes: Employed in processes that require rapid cooling or freezing, such as in the production of ice cream or frozen desserts.
