Qingdao Conqinphi Environmental Technology Group Co., Ltd. is a professional manufacturer with over 10 years of experience in the environmental and food processing equipment industry. Our Double Four-Effect Evaporator with Plate Heat Exchanger is designed to deliver high-efficiency concentration for liquid products, offering a capacity of 500 liters per hour with customizable configurations. Built from premium 304 stainless steel, this evaporator system ensures durability, hygiene, and compliance with international standards, making it an ideal choice for dairy, juice, pharmaceutical, and chemical applications.
This equipment combines the advantages of a four-effect evaporation process with a compact plate heat exchanger design, significantly reducing energy consumption while maximizing product quality. The double four-effect configuration allows for staged evaporation, achieving higher concentration ratios and lower operating costs. Whether you need to concentrate milk, fruit juice, or herbal extracts, our system is engineered to meet your specific production requirements.
Key Features & Technical Specifications
- Double Four-Effect Design: Four evaporation stages in series, with two parallel units for increased throughput and flexibility. Achieves high concentration ratios (up to 50% solids depending on product).
- Plate Heat Exchanger: Efficient heat transfer with minimal fouling; easy to clean and maintain. Ideal for heat-sensitive products.
- 304 Stainless Steel Construction: All contact parts are made of food-grade 304 SS, ensuring corrosion resistance and product purity.
- 500 L/H Evaporation Capacity: Suitable for small to medium-scale production lines; can be customized for higher or lower capacities.
- Customizable Options: Available with different control systems (PLC, touch screen), vacuum pumps, and CIP (Clean-in-Place) systems.
- Energy Saving: Uses vapor recompression and multiple-effect heat recovery, reducing steam consumption by up to 60% compared to single-effect evaporators.
- Compliance with International Standards: Manufactured under ISO9001, HACCP, and other certifications. Suitable for export to global markets.

Detailed Product Advantages
The double four-effect configuration is a unique innovation that allows two separate four-effect evaporators to operate in parallel or series. This design provides flexibility: you can run both units simultaneously for higher throughput, use one unit while cleaning the other, or process different products on each line. The plate heat exchanger design is particularly beneficial for products with high viscosity or heat sensitivity, as it ensures gentle evaporation with minimal thermal degradation.
For customers in the dairy industry, this evaporator can concentrate milk from 12% solids to 48% solids in a single pass, with excellent flavor retention. For juice manufacturers, it can concentrate fruit juice up to 65°Brix without burning. The system is also widely used in the pharmaceutical industry for concentrating herbal extracts and active pharmaceutical ingredients.
Our team of engineers can customize the evaporator to match your specific process parameters, including feed temperature, final concentration, and automation level. Additionally, we offer a complete solution including pre-treatment tanks, pumps, and CIP systems. All equipment is tested before shipment to ensure reliable performance.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a single-effect and double four-effect evaporator?
A: A single-effect evaporator uses one stage of evaporation, while our double four-effect system uses two independent four-effect units, offering higher flexibility, energy efficiency, and the ability to process different products simultaneously. -
Q: Can this evaporator handle viscous liquids like tomato paste?
A: Yes, the plate heat exchanger design is suitable for moderate-viscosity products. For highly viscous materials, we can customize the design with forced circulation or scraped surface heat exchangers. -
Q: What certifications does your equipment have?
A: Our equipment is manufactured under ISO9001, HACCP, ISO14000, OHSAS18001, and other applicable standards. Specific certifications can be provided upon request. -
Q: Is the evaporator easy to clean?
A: Yes, the 304 stainless steel construction allows for CIP (Clean-in-Place) cleaning. We can also provide an automated CIP system as an option. -
Q: What is the typical lead time?
A: For standard models, lead time is approximately 30–45 days. Customized orders may take 45–60 days depending on complexity. -
Q: Can you provide installation and training?
A: Yes, we offer on-site installation supervision and operator training for international customers. Remote technical support is also available. -
Q: What is the warranty period?
A: Our standard warranty is 12 months from the date of shipment. Extended warranty plans are available. -
Q: How do I choose the right capacity for my production line?
A: Our engineers will help you calculate the required evaporation rate based on your feed volume, initial concentration, and desired final concentration. Contact us with your process details.
