Plate-type Four-effect Evaporator for Food Processing Concentration Milk Juice 316SS
Product Spotlights
Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd., a leading manufacturer established in 2015 with a factory size of 10,000-30,000 square meters and an annual export value exceeding US$10 million. Our Plate-type Four-effect Evaporator for Food Processing Concentration Milk Juice 316SS is designed to deliver high-efficiency evaporation for liquid food products such as milk, juice, and other concentrates. Built with premium SS316 stainless steel, this evaporator ensures excellent corrosion resistance, hygiene, and long service life, meeting the rigorous demands of the food industry. With four-effect design and plate-type heat exchangers, it significantly reduces energy consumption while maintaining superior product quality.
Our evaporator is ideal for concentration processes in dairy, beverage, and food processing plants. The plate-type structure offers compact size, easy maintenance, and high heat transfer coefficient compared to traditional tubular evaporators. The four-effect configuration recovers latent heat from vapor, achieving steam savings of up to 50-70% depending on operating conditions. Whether you need to concentrate milk for yogurt production or juice for syrup manufacturing, this equipment provides consistent output with minimal thermal degradation.
Key Features and Technical Specifications
- High Efficiency: Four-effect evaporation system maximizes energy utilization, reducing steam consumption per ton of water evaporated.
- Corrosion-Resistant Material: All product contact parts are made of SS316 (1.4401) stainless steel, suitable for acidic and chloride-containing foods like fruit juice.
- Compact Plate Design: Plate heat exchangers offer up to 3-5 times higher heat transfer coefficient than shell-and-tube exchangers, enabling smaller footprint.
- Gentle Processing: Low temperature operation under vacuum preserves flavor, color, and nutrients of heat-sensitive products.
- Flexible Configuration: Available with forward feed, backward feed, or mixed feed arrangements to suit different product characteristics.
- Automation Ready: Optional PLC control with touchscreen interface for precise temperature, pressure, and concentration monitoring.
- Easy Cleaning: CIP (Clean-in-Place) compatible design reduces downtime and ensures hygienic operation.
- Customizable Capacity: From small pilot scale (50 L/h) to large industrial lines (up to 20,000 L/h).

Frequently Asked Questions
-
What is the typical payback period for this evaporator?
Depending on your steam cost and operating hours, the energy savings often provide a payback within 1-2 years. We can provide a detailed energy analysis based on your data. -
Can it handle viscous products like tomato paste?
Yes, the plate-type design can process moderate viscosity products. For high-viscosity applications, we recommend a forced circulation or falling film plate configuration which is available as an option. -
What maintenance is required?
Routine inspection of gaskets, cleaning of plates (CIP), and checking vacuum system. Gaskets are easily replaceable. We provide a maintenance manual and training. -
Is the evaporator suitable for heat-sensitive products?
Absolutely. The low operating temperature under vacuum (as low as 45°C) makes it ideal for milk, juice, and herbal extracts that require gentle concentration. -
Do you provide installation and commissioning support?
Yes, we offer on-site supervision by our engineers or remote guidance. Our team has extensive experience in food processing projects worldwide. -
What certifications does this product comply with?
The evaporator is designed to meet international food safety standards. Our factory is certified to ISO9001, HACCP, QS9000, SA8000, and others. We can also help you achieve local certifications if required. -
Can I test the evaporator with my product before purchase?
We have a pilot-scale test facility in our factory. You can send samples and witness the concentration process. Alternatively, we can arrange a trial at your site with a rental unit. -
What is the lead time?
Standard units: 45-60 days after order confirmation. Customized units: 60-90 days. We offer expedited shipping for urgent orders.
