Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015, is a professional manufacturer with a factory area of 10,000–30,000 square meters and over 200 skilled employees. We specialize in producing high-efficiency heat transfer equipment for the food and beverage industry. Our Stainless Steel Corrugated Plate Heat Exchanger for Fruit Juice Concentration is designed with a 3-stage configuration and DN50 connections, delivering superior thermal performance and hygienic operation. This unit is ideal for concentrating fruit juices while preserving flavor and nutrients, backed by our rigorous quality management systems including HACCP and ISO9001 certifications.
The heat exchanger features corrugated stainless steel plates that create turbulent flow, maximizing heat transfer efficiency. The 3-stage design allows progressive concentration, reducing energy consumption and improving product quality. DN50 connections ensure compatibility with standard piping systems, simplifying installation and maintenance. Whether you process apple, orange, or tropical fruit juices, this heat exchanger offers a reliable solution for your concentration needs.
Key Features & Benefits
- High Thermal Efficiency – Corrugated plate design increases heat transfer coefficient by up to 30% compared to smooth plates, reducing processing time and energy costs.
- 3-Stage Configuration – Enables precise temperature control and gradual concentration, minimizing thermal damage to heat-sensitive juice components.
- Hygienic Stainless Steel Construction – AISI 304 or 316L stainless steel plates and frames meet food contact safety standards, easy to clean and resistant to corrosion.
- DN50 Standard Connections – 2-inch flanged ports allow quick integration into existing production lines, with optional adapters for other sizes.
- Compact Footprint – Modular design reduces floor space requirements while maintaining high throughput capacity.
- Low Maintenance – Gaskets are replaceable and plate packs can be disassembled for inspection, extending service life.
- Versatile Application – Suitable for concentrating various fruit juices, purees, and other liquid food products.

The 3-stage design optimizes the concentration process by using countercurrent flow. In the first stage, juice is preheated; in the second stage, evaporation occurs under vacuum; and in the third stage, final concentration is achieved. This staged approach allows for gentle treatment, preserving the natural aroma and color of the fruit juice. The corrugated plates create turbulence, reducing fouling and improving heat transfer even with viscous fluids.
Additionally, the heat exchanger can be customized with different plate patterns, gasket materials, and frame configurations to meet specific process requirements. All units are pressure-tested and supplied with a certificate of conformity. Our engineering team provides technical support for system integration, including piping layout and control recommendations.

Frequently Asked Questions (FAQ)
Q1: What types of fruit juice can this heat exchanger concentrate?
A: It is suitable for most fruit juices including apple, orange, grape, pineapple, mango, and tropical blends. The corrugated plate design handles moderate pulp content, though for very high-viscosity or fibrous products, pre-filtration is recommended.
Q2: Why is a 3-stage design beneficial for juice concentration?
A: The 3-stage design allows gradual heating and evaporation, minimizing thermal stress on the juice. This preserves natural flavors, vitamins, and color better than single-stage systems. It also enables higher final concentration levels with lower energy consumption per kilogram of water removed.
Q3: What is the maximum concentration ratio achievable?
A: The achievable ratio depends on the juice type, operating conditions, and system configuration. Typically, apple juice can be concentrated from 12°Brix to 70°Brix or higher. For other juices, we recommend consulting our engineers for a process simulation based on your specific parameters.
Q4: Are DN50 connections standard? Can I adapt to other sizes?
A: Yes, DN50 (2-inch flange) is the standard connection for this model. If you require different sizes (e.g., DN40, DN65), we can provide adapter flanges or customize the frame connections. Please specify your requirements when ordering.
Q5: How do I clean the heat exchanger after processing?
A: The unit is designed for CIP (Clean-In-Place) cleaning. We recommend using food-grade cleaning agents and following a standard CIP cycle (caustic rinse, acid rinse, and water flush). The plate pack can also be disassembled for manual cleaning if needed. Proper cleaning extends gasket life and maintains hygienic standards.
Q6: What certifications does your company hold for food equipment?
A: Our company holds HACCP, ISO9001, ISO14000, OHSAS18001, and also TL900, QS9000, SA8000, among others. These certifications cover quality management, food safety, environmental responsibility, and occupational health. Specific certificates can be provided upon request.
Q7: Is the heat exchanger suitable for vacuum concentration?
A: Yes, the 3-stage design can be integrated with a vacuum system to lower boiling points, which is especially beneficial for heat-sensitive juices. Our frame and gaskets are compatible with vacuum operation down to 0.1 bar absolute pressure. Please confirm your vacuum requirements for proper sealing selection.
Q8: What is the typical lead time for this product?
A: Standard lead time is 30–45 days after order confirmation, depending on quantity and customization. Rush orders can be discussed with our sales team. We maintain a stock of common components to expedite production.
