Stainless Steel Frozen Tunnel Tube Pump Feed Evaporator for Bakery and Confectionery

In modern bakery and confectionery production, rapid and uniform freezing is essential to preserve taste, texture, and shape of delicate products such as pastries, chocolates, and dough-based items. The stainless steel frozen tunnel tube pump feed evaporator is a specialized heat exchanger designed for high-efficiency freezing at ultra-low temperatures, providing reliable performance for industrial bakery lines.

Key Features

1. Stainless Steel Construction

• SUS304 tubes and shell ensure:

• Corrosion resistance against humid and sweet air

• Food-grade hygienic operation

• Long-term durability under freeze-thaw cycles

2. Aluminum-Magnesium Alloy Fins

• High heat transfer efficiency

• Variable pitch design (e.g., 4R20 – 6R12 – 20R6.5) to optimize airflow and minimize pressure drop

3. Pump Feed Refrigerant System

• Compatible with R717 (CO₂) for sustainable operation

• Ensures continuous liquid refrigerant supply to maintain consistent evaporation temperatures

• Supports ultra-low temperature freezing without freezing the refrigerant

4. Water Defrosting

• Gentle water-based defrost cycles remove ice buildup on fins

• Prevents thermal shock to products

• Reduces downtime and energy consumption

5. Ultra-Low Temperature Operation

• Evaporation temperature: down to −42 °C

• Inlet air temperature: around −35 °C

• Allows rapid freezing while maintaining product integrity

Benefits for Bakery and Confectionery Products

• Preserves Shape & Texture: Rapid, uniform freezing prevents deformation of delicate pastries and chocolates.

• Prevents Ice Crystals: Reduces product surface ice, maintaining quality and appearance.

• Food-Safe Design: Stainless steel and hygienic construction comply with food production standards.

• Energy Efficient: CO₂ refrigerant and optimized fin/tube design reduce operational costs.

• Low Maintenance: Water defrosting and durable materials ensure long-term reliability.

Applications

• Frozen pastries, croissants, and dough products

• Chocolates and confectionery items

• Baked goods for retail and industrial packaging

• Ready-to-bake or ready-to-eat frozen bakery products
