Say goodbye to manual sampling — monitor concentration in real time!
With ZHYQ’s Inline Refractometer, every drop of flavor is precisely right.
In the food and beverage industry, where taste consistency and safety define brand reputation, concentration control (Brix, sugar content, solids, etc.) is the invisible lifeline of production.
From jams and juices to dairy and condiments, the right concentration determines the texture, flavor, and stability of every product.
⚙️ Why Concentration Matters
1️⃣ The thickness of jam defines spreadability.
2️⃣ The sugar level of juice determines flavor harmony.
3️⃣ The solid content in dairy impacts texture and nutrition.
4️⃣ The concentration of sauces affects taste intensity and shelf life.
Traditional offline testing methods — manual sampling, lab analysis, or handheld refractometers — can no longer keep pace with modern continuous production lines.
Limitations include:
- ⏱️ Delayed results — by the time lab data arrives, an entire batch may already be off-spec.
- Poor representativeness — single-point samples miss pipeline fluctuations.
- ♀️ Low efficiency — time- and labor-intensive procedures slow production.
- ⚠️ High error rate — influenced by human technique, temperature, and contamination.
- Hygiene risks — repeated sampling increases microbial exposure.
ZHYQ Inline Refractometer — The Invisible Guardian of Quality
Leveraging decades of expertise in precision process measurement, Shanghai Zhaohui Pressure Instrument Co., Ltd. (ZHYQ) has developed a series of high-performance, hygienic inline refractometers tailored for food and beverage applications.
Like a smart taste bud built into your production line, it continuously monitors key concentration points — 24 hours a day, 7 days a week — providing reliable, real-time data with zero contamination risk.
Core Values: Precision · Efficiency · Safety
✅ Real-Time Accuracy — Continuous Process Control
Using advanced ATR prism optics and proprietary algorithms, the ZHYQ Inline Refractometer measures the liquid’s refractive index and converts it into Brix, solids, or customized concentration values (typical accuracy ±0.1 % Brix).
Instant readings allow operators or automation systems to respond immediately — guaranteeing that every can, bottle, or batch meets exact flavor and process standards.
⚙️ Boost Productivity & Optimize Resource Utilization
- No more manual sampling — free up staff for higher-value tasks.
- Automation ready: Concentration data integrates directly with PLC/DCS systems for:
- Precise batching and blending — consistent ingredient ratios.
- Evaporation endpoint control — automatic stop when target concentration is reached, saving energy.
- Mixing and dilution adjustment — maintain consistent product concentration.
- Filling verification — ensure finished product meets specification.
- Reduce waste and rework: Prevent batch deviation before it happens.
️ Food Safety & Compliance by Design
- Hygienic structure: All contact parts use food-grade 316L stainless steel or Hastelloy, surface finish ≤ Ra 0.8 µm, compliant with EHEDG and 3-A Sanitary Standards.
- CIP/SIP cleanable: Eliminates dead corners for complete hygiene.
- Non-contact or sanitary flow-cell design: Minimizes contamination risk, meeting GMP and HACCP requirements.
- Full data traceability: Continuous data logging for audit-ready electronic records.
- Automatic temperature compensation: Integrated high-precision sensor ensures stable accuracy under varying conditions.
- Anti-fouling innovations:
- Optional ultrasonic self-cleaning maintains prism clarity.
- Optimized flow-cell geometry minimizes bubble and particle interference.
- Protective coatings available for high-viscosity or crystallizing media.
- Rugged reliability: IP67 protection ensures long-term stability in humid, wash-down environments.
