On-Line 828 Tobacco

MoistTech understands the sensitive nature of tobacco manufacturing when it comes to moisture levels and developed the model 828 specifically for tobacco applications. The durable design provides the capability to endure the extreme conditions of tobacco factories. Utilizing Near-Infrared (NIR) technology allows MoistTech to provide the best solution for moisture control as it provides an instant measurement without coming into contact with the product.

The 828 model is built to be unaffected by differences in particle size, material height and color, making it the most accurate tobacco sesnor on the market. Providing continuous, reliable readings with only a one time calibration, running maintenance free, and built with a drift free optical design allows operating personnel to immediatly initialize process adjustments based on real-time data. Precision filters and algorithms have been incorporated to optimize performance under the demanding conditions in tobacco processing.

Unmatched in efficiency, reliability, maintainability, life span, and cost of ownership, MoistTech’s 828 tobacco moisture gauge is the answer to controlling moisture in primary processing, leaf processing and cut tobacco applications.

Providing thousands of measurements per second gives the users immediate access to optimize their on-line process to dramatically improve product quality, providing both energy savings and potential increased productivity with lower material losses.

MoistTech has incorporated it’s product loss software capability into the sensor to make small gaps in product, inert material, foreign objects, and belt or screw conveyor measurements are removed from the overall calculation to providing the most accurate and true moisture reading.

Model 828 Installation Locations

Each sensor is equipped with a bracket that can be used to install the sensor from the back or the top. It is recommended to mount the moisture gauge 4-16” (inches) from the product.

Other common ins tallation locations:

  • before and after the dryers
  • conditioning cylinders
  • cutters
  • toaster
  • reconstituted lines
  • belt conveyors
  • screw and drag conveyors

At-line: The addition of the base and stand option provides instant off-line or at-line measurement under on-line operating conditions.

Model 828 Communications

Setting up and communicating with the sensor is easy and can be done with a laptop computer and comes standard with ethernet TCP/IP connection. Utilizing a PC based touch screen operator interface and plant wide network by RS232/422/485. Each MoistTech sensor comes standard with the management software needed to operate the sensor and contains unlimited licensing capabilities, giving you the option to display the moisture in as many places as needed.

Display Options

In addition to the standard software MoistTech provides, there are several read out options available to display the measurement outputs. See display options

Common Tobacco Industry Applications

MoistTech’s NIR analyzer, the model 828 tobacco moisture gauge, is used for on-line tobacco moisture analysis at all locations in tobacco leaf and primary processing. The table below lists the applications and typical range for each tobacco moisture measurement. The accuracy that can be achieved depends on the sampling and testing methods. Whole leaf and strip tobacco will have higher sampling errors than cut finished tobacco due to the variability of the material.


Whole Leaf or Strips GTL Or Primary/Stemmery 5-35% 0.25%
Strips/Threshing 5-35% 0.25%
Re-dried Cut Lamina 15-30% 0.20%
Finished Tobacco Blend 12-18% 0.05%
Cut Rolled Stem, Water Treated Stem 20-50% 0.20%
Expanded Tobacco 5-15% 0.10%
Rolled Tobacco Stem 10-20% 0.15%
Shorts 10-15% 0.20%
Pipe Tobacco 12-25% 0.20%
Chewing Tobacco 10-40% 0.30%
Cigar Filler 10-20% 0.20%
