Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. We are a professional manufacturer established in 2015, occupying a factory area of 10,000-30,000 square meters with 201-300 employees. Our annual export value exceeds US$10 million, serving global markets including North America, Europe, Southeast Asia, Africa, and Oceania. Today, we present our Food Grade High-Salt Wastewater Evaporator specifically designed for soy sauce and pickle processing lines. This compact 220V 3kW evaporator features a PLC control system, ensuring reliable concentration of high-salinity effluents while meeting strict food-grade hygiene standards. With robust stainless steel construction and intelligent automation, it offers an efficient solution for reducing waste volume and recovering water or valuable byproducts.
Key Features & Technical Specifications
- Food Grade Materials: All wetted parts are made from stainless steel (304/316L) to prevent corrosion and contamination, meeting HACCP and other food safety standards.
- PLC Automatic Control: The built-in PLC manages temperature, vacuum level, feed rate, and drainage cycles, minimizing manual intervention and ensuring consistent operation.
- Energy Efficient: With a rated power of only 3kW (220V), this evaporator uses a heat pump or mechanical vapor recompression (MVR) principle (depending on configuration) to optimize energy consumption.
- High-Salt Tolerance: Designed for brine streams with salt concentrations up to 25% or higher, anti-scaling and anti-fouling features prolong maintenance intervals.
- Compact Footprint: The evaporator is skid-mounted and occupies minimal floor space, ideal for small to medium soy sauce and pickle production lines.
- Customizable Capacity: Standard models offer evaporation rates from 50 L/h to 500 L/h; we also provide custom solutions based on your specific wastewater composition.

Detailed Product Description
The Food Grade High-Salt Wastewater Evaporator is engineered to concentrate the brine effluent generated during soy sauce brewing, pickle brining, and similar processes. Traditional disposal of high-salinity wastewater is costly and environmentally challenging. Our evaporator reduces the liquid volume by up to 90%, leaving a concentrated brine or crystallized salt that can be reused or disposed of economically. The PLC control ensures precise regulation of evaporation temperature and vacuum level, preventing thermal degradation of organic compounds and maintaining the possibility of recovering valuable flavor components (e.g., soy sauce concentrate).
How It Works: The wastewater is fed into a heat exchanger where it is heated under controlled vacuum. Vapor is condensed and collected as distilled water (which can be recycled for cleaning or dilution), while the concentrated brine is discharged from the bottom. The system operates continuously with automatic cleaning cycles to reduce scaling. A key advantage is the low energy consumption – the 3kW input drives a heat pump that recycles latent heat, achieving an energy efficiency ratio (COP) typically between 3.0 and 5.0 depending on operating conditions.
Customer Benefits:
- Cost Savings: Lower waste disposal fees and potential water reuse reduce overall operating expenses.
- Environmental Compliance: Helps meet discharge regulations by separating clean water from pollutants.
- Increased Production Flexibility: The compact design allows installation in existing production lines without major civil works.
- Easy Operation: The PLC interface provides real-time data on temperature, pressure, and flow, with alarms for abnormal conditions.
We also offer optional features such as CIP (Clean-in-Place) systems, remote monitoring via Ethernet, and customized automation according to your specific requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum salt concentration this evaporator can handle?
A: Our standard design can handle brine with salt content up to 25% (250 g/L). For higher concentrations, we offer customized versions with anti-scaling coatings and enhanced discharge systems. -
Q: Can this evaporator recover soy sauce flavor compounds from wastewater?
A: Yes, under low-temperature vacuum evaporation, volatile organic compounds responsible for flavor can be condensed separately. We recommend testing with your specific liquor to verify recovery efficiency. -
Q: What is the typical electricity cost to operate this 3kW evaporator?
A: At full load, it consumes 3 kWh per hour. Actual operating cost depends on local electricity price and duty cycle. For a 50 L/h evaporation rate, the energy consumption per liter of water removed is approximately 0.06 kWh. -
Q: Do you provide installation and commissioning service?
A: Yes, we offer on-site installation guidance and commissioning support. Our engineers can also train your staff remotely or on site upon request. -
Q: What materials are used for the food-grade version?
A: We use SS304 for general applications and SS316L for highly corrosive environments (e.g., high chloride). All seals and gaskets are FDA-grade silicone or PTFE. -
Q: How often does the evaporator need maintenance?
A: With automatic cleaning cycles, routine inspection every 3 months is recommended. Critical components like pumps and valves have a lifespan of 2–3 years under normal use. -
Q: Can I use this evaporator for other high-salt wastewaters, such as from cheese production?
A: Yes, as long as the wastewater is food-grade and free of coarse solids that could clog the heat exchanger. Pre-filtration may be required. -
Q: What certifications does your company hold?
A: We are certified with HACCP, ISO9001, ISO14000, OHSAS18001, SA8000, and several other management standards. Please contact us for certificate copies.
