Stable, low-maintenance measurement for both cane and beet sugar production—from juice clarification through crystallization

Sugar processing demands continuous, reliable Brix measurement across some of the most challenging conditions in industrial food production—concentrations ranging from 12°Brix clarified juice to 98°Brix massecuite, extended production campaigns lasting weeks or months, and process environments where product coating on sensor surfaces is inevitable.
Whether processing cane sugar or beet sugar, these measurement challenges remain consistent: Conventional optical refractometers struggle with surface fouling that causes signal drift during production runs, requiring frequent cleaning that interrupts operations. At high Brix levels above 85%, optical measurement becomes unstable. And in crystallizing applications, suspended crystals cannot be measured at all.
Inmec’s digital microwave sensors deliver stable Brix measurement throughout both cane and beet sugar production—from dilute juice streams through high-concentration syrups and crystallizing massecuite—without sensitivity to coating, crystal content, or the demanding conditions typical of sugar factory operation.
Maintains accurate Brix readings even when product fouling occurs on sensor surfaces—a common reality in both cane and beet sugar processing that causes optical sensors to drift and require constant cleaning.
Accurate measurement from 10°Brix thin juice through 98°Brix massecuite without changing sensors or measurement principles—covering the full concentration spectrum in both cane and beet sugar production.
Delivers consistent Brix data throughout extended production campaigns—from seasonal beet campaigns lasting months to year-round cane processing—with minimal maintenance requirements.
From vacuum pans and evaporator stations to storage vessels and process pipelines, Inmec technology supports measurement throughout the sugar house—providing continuous, reliable Brix data where process control depends on accuracy that doesn’t drift during extended campaigns.
While cane and beet sugar production differ in raw material and specific process conditions, the fundamental measurement challenges remain consistent—and so does the solution.
The advantage: Regardless of whether you process cane or beet, Inmec sensors deliver the same stable, low-maintenance performance across your entire production process.
| Aspect | Cane Sugar | Beet Sugar | Inmec Solution |
|---|---|---|---|
| Raw material | Sugar cane juice | Beet thin juice | Measures both effectively |
| Typical Brix range | 10-98% (juice to massecuite) | 12-75% (thin juice to white pan) | Stable across full range |
| Process temperature | Higher (juice evaporation) | Moderate (extraction to crystallization) | Temperature compensated |
| Common challenges | High temps, color bodies, coating | Non-sugars, foam, coating | Coating-resistant in both |
| Crystallization | Multiple grades (A/B/C massecuite) | Primarily white sugar | Handles all crystal types |
| Campaign type | Continuous or seasonal | Seasonal campaigns (100-200 days) | Designed for extended runs |
| Measurement needs | Juice, syrup, massecuite, molasses | Thin juice, thick juice, white pan | One platform serves all |
Optical sensors measure at an optical interface
Light passes through a prism or sapphire window into the product. Any coating or buildup on this surface directly affects measurement accuracy, causing drift that requires cleaning and recalibration—a challenge in both cane and beet sugar processing where coating is inevitable.
Inmec sensors measure bulk dielectric properties
The microwave measurement volume extends into the product stream or tank contents. Surface coating on the sensor walls does not affect measurement, allowing continuous operation even when fouling occurs—equally effective in cane juice, beet juice, syrups, and massecuite.
The result: Sugar production involves coating—it’s unavoidable whether processing cane or beet. The question is whether your measurement technology can handle it, or whether it creates a maintenance burden that interrupts production and undermines control reliability.

Engineered for sugar production’s toughest measurement challenges: evaporators, vacuum pans, and crystallization processes in both cane and beet sugar operations.

Whether processing cane or beet—measurement technology that handles coating, high concentrations, and extended campaigns without the maintenance burden of optical sensors.
