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.

An Inline Refractive Index Analyzer for Measuring Sugar Content in Food and Beverages

The Electron Machine MPR E-Scan™ provides inline refractive index measurement of cane sugar, HFCS (High-Fructose Corn Syrup), or beet sugar concentration in food products. The analyzer continuously reads the °Brix value of fruit juices, soft drinks, fruit juice, syrups, jams, jellies, honey, and nectars.

The MPR E-Scan™ is a refractive index °Brix  monitor that provides highly accurate inline sugar concentration measurements. The inline installation (with local or remote electronics) offers lower-cost operation and monitoring and control.

The MPR E-Scan™ includes a high-resolution color display, and a 4-20mA output is standard. HART® protocol, RS-232, and RS-422 outputs are available, providing you a means for data acquisition as well as visualization of all data, alarms, trends, and allows real-time product adjustments. The entire package is NEMA 4X rated and designed and manufactured with the best materials for each application to provide years of trouble-free service with minimal maintenance.

Inline Process Refractometers in Tomato Processing

Inline Process Refractometers in Tomato Processing

It's obvious that tomato processors have a need to predict product yield, consistency and quality, as these variables directly affect sales and profitability. However, consistency and quality in tomato products is fairly difficult to control because of the fruit variation, harvest maturity, and farming area.

Consumers often select tomato sauces, pastes, purees and dressings based on sweetness levels, so it's very important food producers to accurately control sweetness. The common method for measuring sweetness in this industry is by reading Brix. Degrees Brix (°Bx) is the measure of the amount of sugar in an aqueous solution and is used because it's reliable and fast.

Refractometry is used to determine degrees Brix, and refractometers are the instruments used for the measurement. Very basically, refractometers use a prism to determine how light bends through a substance. The change in light direction is then used to repeatably determine certain values - in this case Brix.

There are several types of refractometers in food processing. Many food processing labs do batch sampling through the use of hand-held refractometers. Another type is the inline process refractometer.  It is used to provide a Brix measuring control loop right on the production line, and can be employed anywhere in the overall process from evaporation stages up to the concentrated final product.

Inline Process Refractometer

Inline process refractometers are installed using a sanitary-type pipe adapter, designed and manufactured to appropriate 3-A Sanitary Standards. Should the tomato product be known to produce stubborn coatings on the refractometer prism, a steam port is added to the adapter to allow the prism to be steam cleaned at specific intervals.

The head of the refractometer is mounted directly in the processing line and provides real-time detection of Brix with a measurable output. The refractometer's circuitry then conditions the head's output and compares it to a desired value in a controller. The controller provides a corrective output signal, such as 4-20mA, to a final control element, such as a control valve. The control valve increases or decreases the amount of an ingredient to keep things in balance. Not unlike any other process control variable (pressure, temperature, level or flow), Brix measurement is determined and controlled via it's own control loop by the inline process refractometer,  providing the tomato processor greater control over product quality and consistency.
