Cookies, Crackers and Rice Thins

Provide quantitative data to monitor process quality.

Vision Inspection of Cookies, Crackers and Rice Thins

Dimensional and color characteristics are important to cookie, cracker, wafer, and rice cake producers, and it can be difficult to quantify those traits with visual and manual inspection methods.

An over-line or in-line vision monitoring system can provide continuous, quantitative data that can be used to identify process issues, make real-time changes, and create a library of information for analysis. A bench-top vision system allows for statistical analysis from different production lines, providing instantaneous data and images, along with historical reporting.  An off-line vision tool removes subjective grading of products, manual measurements, and data entry; replaced with consistent, quantitative results.

An in-line vision system equipped with a rejection module will automatically remove faulty product, particularly those pieces that will cause stacking and/or packaging disruptions.

Inspection System Measurement Capability

Whether you want to sample or provide 100% inspection, Montrose Technologies has a solution to match your application.


The complete, stand-alone SnapQC™ system uses a high-speed, non-contact imaging method to capture a wide range of object information such as color, height, diameter, slope, symmetry, length, volume and weight.


The MT-Series™ of in-line systems allow 100% inspection with top and bottom color and a full set of rejection options. The systems are easy to use, sanitize and have a low annual maintenance cost and provide real-time data for operators.


FocalPoint™ over-line systems can be incorporated into an existing production line. They are easily installed, versatile, low-cost turn-key solutions for continuous inspection which provide real-time data for operators.

Types of Analysis and Rejection

Vision inspection systems employ high-speed cameras and lasers in combination with Montrose imaging software to detect and measure randomly oriented and sized objects on a conveyor belt. Data from the laser and imaging devices produce 2D, 3D and color information which is fed into the analysis software. LED lighting systems are designs with the specific product the system is analyzing to ensure the most efficient imaging occurs. Each system, whether benchtop, in-line or over-line, is designed along the same principles. The laser and profile camera produce the three-dimensional information while the separate top and bottom camera perform the two dimensional and color analysis.

Rejection systems vary between systems and product types and are designed according to customer specification. Montrose develops and manufactures a complete set of solutions for the baked goods and snack food industry.

Vision System Components

In-line and Over-line Inspection

The type and size of food product transported through the vision system will determine the number of cameras needed for the measurement requirements, the individual product rejection method, and hygienic/environmental considerations.  Furthermore, vision inspection systems may include other customized material handling solutions such as automatic de-kissing of product, automatic box loading, and multi-route sorting.

Improve quality, reduce production costs, provide valuable data.
