Process NIR Applications for Food Manufacturers

The MCT466-SF On-Line NIR Smart Sensor has been utilized by food manufacturers to track and control moisture, oil/fat, and product temperature at the time of the process for several kinds of food, including:


  • Snack foods (potato/corn chips, popcorn, tortillas, cookies/crackers, pretzels, pork rinds, etc.)
  • Milk powders
  • Breakfast cereals
  • Extruded Snacks
  • Oil-based flavorings

How It Works

Proven Technology for Food Applications

The MCT466-SF NIR analyzers are combined into main areas of a production process to constantly track incoming raw materials or control processes on the production line. Every option has been developed to integrate smoothly over auger/screw conveyors, belt conveyors, or bins and chutes to examine oil, moisture, and other on-line measurements.

The MCT466-SF scanning process is easy but dependable:

  1. Light from the lamp has been directed via a rotating wheel at 2000 rpm consisting of NIR filters chosen for the application
  2. NIR light has been directed onto the product being quantified
  3. The light reflected off the product has been captured with the help of a mirror inside the unit and concentrated onto a Peltier Cooled lead sulfide detector
  4. The detector’s output has been taken by the on-board “smart” circuit board and compared to the internal reference beam. Further, this is converted into a percent of oil, moisture, and other parameters.

System Components

The MCT466-SF is known as a stainless-steel enclosure including a local display, which has all the power, digital, and analog inputs for functioning the system. This enables a simple installation process for the majority of the applications.

Installation Options

Over-Belt Conveyor

MCT466-SF sensors have been mounted 8 to18″ above the conveyor, perfectly with constant product flow.

Augers & Screw Conveyors

Setting up the MCT466-SF on top of augers and screw conveyors enables a measurement of the flow of material that is being conveyed by the flights of a screw. The MCT466-SF has been installed offset to the side of the central shaft while the impact of the flights passing the unit is removed by the software of the instrument.

Bins and Chutes

Sight glass windows, like Sapphire, can be utilized for the continuous flow of products against the window. Besides, the snorkel sampler (sold individually) could be utilized to quantify free-falling powders or granules in chutes.
