Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. — a professional manufacturer with over a decade of expertise in thermal concentration systems. Our Stainless Steel Falling Film Evaporator for High Solids Jam is engineered to deliver superior evaporation efficiency while preserving the natural flavor, color, and nutritional value of your fruit-based products. Constructed from premium 304 stainless steel, this equipment ensures long-term hygiene, corrosion resistance, and easy cleaning — ideal for jam, jelly, and fruit puree with high solid content. With our advanced falling film technology, you can achieve consistent concentration ratios up to 70% solids with minimal energy consumption.
Key Features & Technical Specifications
- 304 Stainless Steel Construction — All product-contact parts are made of food-grade 304 stainless steel, meeting HACCP and ISO9001 standards. Surface finish Ra≤0.4μm prevents bacterial growth and facilitates CIP cleaning.
- Falling Film Evaporation Principle — Liquid flows as a thin film along vertical heat exchange tubes, maximizing heat transfer coefficient (up to 1500–3000 W/m²·K) and reducing residence time to avoid flavor degradation.
- High Solids Handling Ability — Specially designed distribution system and enlarged downcomers prevent clogging and fouling when processing thick jam with pulp content up to 80%.
- Energy Saving Design — Multi-effect configuration (optional) can reduce steam consumption by 40–60%. Integrated vapor recompression (TVR/MVR) available upon request to minimize operating costs.
- Flexible Capacities — Standard evaporation capacities range from 100 L/h to 5000 L/h, fully customizable for small craft producers to large industrial lines.
- Intelligent Control System — PLC with human-machine interface (HMI) allows precise control of temperature, vacuum level, feed rate, and product outlet concentration. Auto-recording and alarm functions.
- Sanitary Design — All welds are ground and polished, no dead corners, and the system supports Clean-in-Place (CIP) and Sterilize-in-Place (SIP) protocols.
- Optional Vacuum Operation — For heat-sensitive ingredients, vacuum operation (down to -0.09 MPa) lowers boiling point to 55–65°C, preserving delicate fruit flavors.

Our falling film evaporator is widely used in fruit processing facilities for jam, fruit concentrate, sauce, and puree. Compared to traditional boiling pans, it offers 30–50% higher thermal efficiency and more uniform product quality. The gentle evaporation process prevents scorching and minimizes flavor loss — critical for premium high-solids jam.
Why Choose Qingdao Conqinphi?

Frequently Asked Questions (FAQ)
-
Q: What is the maximum solid content this evaporator can handle for jam?
A: Depending on the fruit type and pulp size, our falling film evaporator can concentrate jam from 12–45% initial solids to final solids of up to 72%. For extremely viscous products, we recommend a scraped surface pre-heater or optional finned tubes. -
Q: Can this evaporator process jam with large fruit pieces or seeds?
A: Our design incorporates a special feed distribution system with larger passages that can handle pulp pieces up to 10mm. For seeds or larger particles, a pre-filter or strainer is recommended to protect the heat exchange surface. -
Q: How often does the evaporator need to be cleaned?
A: Cleaning frequency depends on the product and operating hours. Typically, a CIP cycle every 8–12 hours of production is sufficient. We provide an automatic CIP package as an option. -
Q: What is the typical energy saving compared to a traditional open boiling pan?
A: A single-effect falling film evaporator can save 30–40% steam; a double-effect configuration saves 50–60%; triple-effect saves up to 70%. Energy payback is usually within 1–2 years. -
Q: Do you offer vacuum operation for preserving fruit flavor?
A: Yes. An optional vacuum system can be integrated to lower the boiling point to 55–65°C, minimizing thermal degradation of heat-sensitive compounds like pectin, vitamins, and natural aromas. -
Q: What is the delivery lead time?
A: For standard capacities (100–2000 L/h), lead time is approximately 45–60 working days. Customized solutions may require 60–90 days. We will confirm after design review. -
Q: Can I get a custom design for my specific jam recipe?
A: Absolutely. We provide tailored solutions based on your product viscosity, solid content, and production volume. Our engineering team will simulate the process to ensure optimal performance. -
Q: Does the equipment comply with international sanitary standards?
A: Yes. Our evaporators are manufactured according to HACCP guidelines, with 304 stainless steel, smooth welds, and crevice-free design. Optional 316L is available for acidic products. Certificates like ISO9001 and CE can be provided upon request.
