Due to multiple raw ingredients suppliers, variations and inconsistencies must be corrected. Cooking, mixing, speed, and duration must be highly exact in order to achieve compatible viscosity and the final, desired texture. For this case, we will use processed cheese as an example.
Cooking application; viscosity measurement for melted cheese
When melting salts are added to other ingredients, the melted cheese consistency changes and it can be too thick or too thin. When either occurs, manufacturing process face frequent downtime due to unpredictable product variations. Ultimately, final product quality is not met.
Sofraser Inline viscosimeter solutions for cheese process industries
A MIVI process viscometer paired with its associated processor easily monitors melted cheese during the manufacturing and maturation processes by determining its physical characteristics and correlating them directly to viscosity. One of the MIVI viscometer significant characteristics is the 3A design sanitary mounting which eliminates bacteria proliferation. The viscometer is cleaned in place so there is no need to uninstall it from the process.
In order to achieve consistent end-product quality and to maintain zero customer claims regarding product consistency, the installation of a MIVI process viscometer achieves all aspects of production efficiency by determining ideal operation characteristics. Since the MIVI corrects ingredient variations and increases savings, ROI is generally realized within six months of the installation.

In Refineries and Petrochemical processes, on-site control is of primary importance with regards to product quality.
The use of reliable viscosity measurement is critical to refineries for safe characterization and handling the products. It became essential for better process control while increasing output capacity to meet ever growing demands. Visbreaking is one of several cracking methods used in the petroleum industry to process crude oil and petroleum products for commercial use. Developed in the late 1930s, it is used to produce more valuable products while maximizing end-product profitability.
How to define visbreaking process?
Visbreaking is a mild form of thermal cracking, with primarily aim to lower the viscosity of vacuum residues. Two visbreaking processes are available: the coil or furnace type and the soaker type. In each process, viscosity control is necessary to adjust heating parameters and optimize distillation.
It is a liquid-phase thermal cracking process used to convert heavy or high viscosity petroleum stocks to lower viscosity fractions suitable for use in HFO. Visbreakers are now designed to maximize yield of valuable gas oil and other lighter ends used in fuel blending.
In our application datasheet, we explain in detail the 3 main objectives of visbreaking:
– Reduce the viscosity of the feed stream as much as possible without significantly affecting fuel stability
– Reduce the amount of residual fuel oil produced by refineries
– Increase the proportion of middle distillates in the refinery output
Viscosity measurement in visbreaking process
Inline viscosity measurement may be used in several steps during the visbreaking process to help preventing fouling and increase yield. Viscometers may help characterize the incoming feedstock for adjustment of heating parameters. Viscometers may also monitor the visbreaker outputs to ensure that sufficient fuel oil and light ends have been removed from the bottom residues.

Controlling the viscosity index (VI) of lubricants and hydraulic fluids is an essential step in many manufacturing processes of the petroleum industry. Viscosity and fluidity have a considerable influence on the quality of the end product.
Many industries use the properties of viscosity in their industrial processes and integrate them into their manufacturing standards.
When oil viscosity is mentioned, it is necessary to specify at what temperature it has been measured.
The viscosity index is a standardized quantity which takes into account the influence of temperature on the kinematic viscosity. The more this viscosity index is important, the less the viscosity is influenced by the temperature.
How to calculate viscosity index?
Its calculation method is described in ASTM D2270. The viscosity index is based on the viscosity measurement at 2 reference temperatures: 37.8°C (100°F) and 98.9°C (210°F). In the oil production process, measurement and calculation of the viscosity index is a real challenge because it is necessary to measure the viscosity of the oil at these two reference temperatures while the manufacturing process may be at a different temperature.
Measurement solutions at 2 reference temperatures:
The analyzers have clear advantages over process viscometers in measuring the viscosity at reference temperature of oils and lubricants. Indeed, the measurement is carried out at the actual reference temperature whatever the behavior of the process.
There are two types of analyzers:
Using a pump, they perform a dynamic viscosity measurement and therefore aren’t directly correlated to the D445 standard. Indeed, they require the use of an external density meter to calculate the kinematic viscosity. To determine the viscosity index, it is necessary to install two analyzers, one for each reference temperature.
- The on-line analyzer based on the vibrating viscometer:
A single analyzer allows on-line measurement at 2 reference temperatures and the calculation of the viscosity index according to ASTM D 2270-04.
ATEX Zone 1, Sofraser Thermoset In-line analyzers provide all the guarantees of continuous viscosity index control.
The Thermoset KV is the only analyzer able to directly measure the kinematic viscosity with a single measuring probe and providing measurements in cSt.
The Thermoset LT is the simplest and most economical solution on the market, measuring dynamic or kinematic viscosity in cyclic mode (fluid’s sampling temperature being significantly higher than 40 and 100 °C). These solutions are robust, cost-effective and require almost no-maintenance while providing lasting satisfaction.
