Moisture In Finished Tobacco

The continuous measurement of moisture in tobacco is a key consideration in the production of tobacco.? The proper moisture level of finished tobacco has an impact on production speed and tobacco quality.? By installing the MCT360-T in the processing area, a manufacturer can continuously monitor the moisture content and either manually or automatically make control decisions.


The MCT360-T is typically installed over a full conveyor prior to the making area.? ? The MCT should be positioned about 8″ from the tobacco bed and perpendicular to the moving conveyor.? It is always to important to make sure during the MCT’s installation there are no gaps or interruptions in the product flow.

Moisture measurement in finished tobacco is a vey well understood and documented application.? NIR wavelengths, calibrations,? algorithms and sensor optical parameters are pre-set at the PSC factory.

Attention Snack Food Manufacturers: Seasoning and Flavoring Application

NIR Analyzers have been assets to the Snack Food Industry for a number of years.? They have been widely used and are an accepted method of analysis in many environments and used for a variety of applications.

One interesting application is the automatic controls of flavoring addition for both cheese curls and popcorn.? An NIR sensor is installed on a conveyor after a tumbler.? The tumbler applies the flavoring in a form of a slurry and the NIR sensor actually measures the oil content of the slurry.? The amount of oil in the slurry has a direct relationship to the total amount of flavoring being applied.? The NIR sensor’s 4-20mA output is connected into a process controller that automatically adjusts the amount of flavoring applied by manipulating a pump to a desired set point.

Soup Packaging

Soup in polyethylene bags exiting a chiller and entering the packaging line, monitored by Process Sensor?s infrared thermometer model PSC SSS-Laser.

The Application

In the Food Industry, plant cleanliness and maintaining a bacteria free product are primary concerns. To eliminate bacterial development, it is critical to maintain foodstuffs and processing equipment at temperatures below 41?F.

Truesoups, a division of H.J. Heinz Co., ( SIC code 209903 Food products ) provides frozen, ready to heat and serve soups. At its manufacturing plant located in Kent, Washington State, soup is conveyed in polyethylene bags to a chiller.

After exiting the chiller, the bags pass into the field of view of a Process Sensors model PSC SSS-Laser infrared thermometer with a spectral response of 8 to14?.

Clear polyethylene plastic transmits 90% of IR energy in that waveband. The spectral response also avoids the atmospheric moisture absorption bands that are present at either side of it. This feature can be important in food processing where steam and water vapor is often present.

At this time, the customer is using only the 4 -20mA output to display the temperature on an indicator, but according to Process Engineer, Dave Jametski, he plans to employ the Ethernet output for computer data acquisition using Process Sensor?s CompactConnect software package.

Jametski says that the stored data will be an essential tool in investigating product problems that often may only come to light after manufacture.

Application Tips

Food processing plants require some unique factors to be taken into account. First is the presence of steam and water vapor in the atmosphere. This may require air purging, but the source of air must be pure so as not to contaminate the product.? ? It is often better to use nitrogen for this reason.

If water-cooling is required, for meat cooking applications, care must be taken not to overcool, as this will cause condensation to form on the lens. The sensor should be positioned so that condensate does not drip onto the
product or the cooling flow must be regulated, thereby not exceeding the dew point that would cause condensation.

Food processes are frequently hosed down with hot water, or in some cases steam, so it is important to seal signal and power cable entry points. A long sight tube or gate valve can be used to protect the lens if necessary.

The Market

Applications for infrared thermometers in food processing are abundant and varied; from monitoring frozen fish on fish-stick cut up lines, to measuring and controlling sealing jaws on plastic bag sealing machines.

Processes are usually highly automated, with limited operator attendance, increasing the importance of monitoring, control and data acquisition instrumentation. OEM?s include continuous and static oven builders,
microwave and steam-kettle cooker manufacturers. Mixer and mechanical handling companies are also good prospects.

New IR Sensor Introduction


Downsizing infrared thermometers usually involves sacrificing features and performance. Process Sensors? model PSC-SSS-3M sets a new standard in its uncompromising sophistication and capability. The sensing head, which is only 14 mm diameter by 28 mm in length, facilitates temperature measurement in the confined circumstances often found in industrial processes.

A wide overall temperature span of 50 to 600?C, a narrow spectral response of 2.3?m, and target spot sizes of from 7 to 48 mm or 7 to 73mm dia., depending on the model, particularly suit the sensor to secondary metal processing, and the measurement of oxides and ceramic materials.

Signal processing and programming electronics are contained in a rugged 70 x 89mm housing that allows mounting up to 3m from the sensor, providing greater immunity from electromagnetic interference, mechanical shock, and high ambient temperatures. The sensing head is able to withstand ambient temperatures of up to 85?C without cooling.

Functions provided by the signal processing and programming unit include: analog outputs of 0/4-20mA, 0-5/10V, J and K thermocouple and alarm.? Optional digital outputs are: USB, RS 232, RS 485, Profibus DP and Ethernet.? Programmable parameters include emissivity and transmissivity adjustments, peak and valley hold, averaging, and extended hold with threshold and hysteresis.

Process Sensors Corporation PSC Spot Software? supports sensor set-up, multi-tasking, graphic display of temperature trends and data logging, and in general allows the user to customize the sensor to the application. Detailed specification information can be found at

Online % Solids Analysis Sludge Cake-Sewerage Treatment

Biosolids are an unavoidable bi-product of sewerage treatment.? However, through careful treatment, Biosolids can be recycled and used effectively as fertilizer and compost as as for combustion processes.? Water must be removed from sludge in order to minimize transportation costs as well as to render it suitable for agricultural or combustion purposes.? This form of sludge is described as sludge “cake.”

Sludge Treatment Processes

The sludge undergoes digestion, a heating process which destroys the bulk of present pathogens prior to passing through large dryers and a pelletizer.? Alternatively, the sludge is “lime stabilized.”? The addition of CaO (lime) to sludge results in a exothermic chemical reaction which eliminates pathogens.

Gauge Location and Installation

Gauge location is dependent on the Treatment Process, however, installation above a belt conveyor, if possible, is simple and effective.? In order to improve measurement performance, the installation of a doctor blade prior to the gauge location, helps to break up and spread the cake solids over the belt, thereby presenting a fresh surface of product to the gauge.? Implementation of two doctor blades (one perpendicular to belt direction and another obluque to the blet) to channel product onto a transfer conveyor will provide the best results.

The % solids readout can be used to control the centrifuge, press and dryer operation as well as the rate of lime addition where applicable.

Measurement Performance

Measurement accuracy is dependent on the composition of the sludge and how variable it is over time, also on the % solids level.? In most instances, however, the % solids reading is accurate to within +/- 0.5%.
