Process Refractometers for Fruit Juice Production Quality & Consistency

A process refractometer is a device that measures the refractive index of a liquid, which is a measure of how much the light passing through the liquid is bent. The refractive index of a liquid is influenced by the concentration of dissolved solids in the liquid, such as sugars, proteins, and other compounds.

In the context of fruit juice production, inline process refractometers are used in the production of fruit juices to measure the concentration of soluble solids in the juice as it is being processed. The concentration of soluble solids is an important quality parameter in fruit juice production because it determines the sweetness and flavor of the juice. Feedback from the refractometer adjusts the concentration of the juice by adding or removing water or other ingredients to achieve a desired level of sweetness or other desired characteristic.

To use an inline process refractometer in the production of fruit juices, a small sample of the juice is analyzed directly in the production line through the refractometer's measurement prism. The refractometer then measures the refractive index of the juice sample as light passes through the sample. The refractive index is directly related to the concentration of soluble solids in the juice, so the refractometer can calculate the total dissolved solids (TDS) of the juice by using a pre-determined conversion factor. 

By accurately measuring the concentration of dissolved solids in the juice, a process refractometer can help to ensure that the juice meets quality standards and has a consistent flavor profile. It can also be used to optimize the juice production process by helping to identify bottlenecks or inefficiencies and allowing for adjustments to be made to improve efficiency and reduce waste.

Inline process refractometers are typically used in conjunction with other process control instruments, such as pH meters and temperature sensors, to ensure that the juice is being produced to the desired specifications. They are also commonly used in the production of other beverages, such as beer and wine, as well as in a variety of other industrial processes.

Overall, the use of a process refractometer can help to improve the quality of fruit juices by ensuring that they meet desired standards for sweetness, flavor, and other characteristics, and by helping to optimize the production process.

Inline Process Refractometers for Tomato Processing

Tomato processors need to anticipate product output, consistency, and quality, as these variables directly impact sales and profitability. However, because of fruit diversity, harvest maturity, and agricultural region, it is challenging to control the consistency and quality of tomato products. 

Consumers frequently choose tomato sauces, pastes, purees, and dressings depending on sweetness levels, so food producers must manage sweetness precisely. Brix is the most commonly used method for assessing sweetness. Degrees Brix (°Bx) is a quick and accurate way to calculate the quantity of sugar in an aqueous solution. 

Refractometry calculates degrees Brix, and refractometers are the devices used to do so. Refractometers, in essence, use a prism to determine how light bends through a substance. The shift in light direction calculates to particulate quantities - in this example, Brix - in a repeatable manner. 

In food processing, there are various types of refractometers. Many food processing labs employ hand-held refractometers for batch sampling. The inline process refractometer is another. It offers Brix measuring control directly on the manufacturing line, and it can be used anytime in the overall process, from the evaporation stages to the concentrated finished product. 

Inline process refractometers are mounted using a sanitary-type pipe adapter designed and produced per 3-A Sanitary Standards. Suppose the tomato product is known to leave persistent coatings on the refractometer prism. In that case, a steam port is added to the adapter, allowing the prism to be steam cleaned at predetermined intervals. 

The refractometer's head is positioned directly in the processing line and provides real-time Brix detection with a measured output. The refractometer's circuitry then conditions the head's signal and compares it to the desired value in a controller. The controller provides a corrective output signal, such as 4-20mA, to a final control device, such as a control valve. The control device increases or reduces the amount of an ingredient. Brix measurement, like any other process control variable (pressure, temperature, level, or flow), is determined and managed by the inline process refractometer via a dedicated control loop, giving the tomato processor better control over product quality and consistency.

Inline Refractometers for Quality Control and Monitoring in the Pharmaceutical, Food & Beverage, and Chemical Industries

The Inline Process Refractometer is a measurement device used to determine concentration levels in the process media. The combined hardware and software continuously monitor the process in real-time and provide output signals that assist in monitoring and controlling the process.

Inline Process Refractometers accurately measure solids concentration, density, and purity levels. Industries such as sugar, food & beverage, chemical, paper, and pharmaceuticals commonly apply refractometers to their manufacturing processes.

Refractometers measure the amount of light that passes through a sample and then measure its refractive index to determine its concentration or composition. Their primary uses are quality control, product development, process optimization, and research. 

Pharmaceutical Industry

The process refractometer is used in pharmaceutical industries to measure the concentration of solids in a solution for quality control, such as checking the purity of water or other liquids. They are used to measure the makeup of solutions containing active ingredients to ensure that they meet predetermined specifications.

Food and Beverage Industry

Industrial refractometers provide a variety of benefits in the food industry. Since the primary function of an Inline Process Refractometer is to measure the concentration of dissolved solids in a liquid, in food processing, they measure sugar content, alcohol content, or water concentration by calibration to measure some specific solute or solutes. These solutes can be either sugars or salts, depending on the application.   Companies use Inline process refractometers to produce fruit juices, tomato products, dairy products, sweeteners, jams, and jellies, to determine the sugar content.

Chemical Industry

The chemical industry uses Inline Process Refractometers for the chemical analysis of liquids. They determine the magnitude of dissolved solids in a liquid solution by measuring the angle at which light passes through, assisting in deciding concentrations, and identifying chemical compounds.
