Kill-Step Validation for the Baking Process

Kill-step validation for your baking process is easy with the SCORPION® 2 Profiling System and Data Logger from Reading Thermal.

Reading Thermal, a Reading Bakery Systems brand headquartered in Sinking Spring, Pennsylvania, has been focused on the science of commercial baking processes for more than 25 years. We manufacture and support the state-of-the-art SCORPION® 2 Profiling System. No other system makes achieving desired levels of food safety and throughput so simple.

Advantages of Validating a Kill Step:

  • Helps achieve maximum food safety and protects consumers.
  • Helps meet the safety standards (e.g., five log reduction of pathogenic  coli/Salmonella) set by regulatory agencies.
  • Helps determine effective treatment.
  • Saves millions of dollars for the food industry by avoiding recalls and other legal penalties due to foodborne illness outbreaks.
  • Reinforces consumer confidence.
  • Supports business success.

The Reading Thermal SCORPION® 2 Temperature Sensor Array is designed to measure temperature at product level, in fixed positions across the conveyor, and delivers a true representation of what your product is experiencing over time.

The sensor array is connected to the SCORPION® 2 Data Logger and then travels through the oven with the product, yielding a precise picture of temperature from side-to-side and end-to-end.

There are different types of pluggable sensors available, including one designed for solid or tight mesh conveyors and one for open mesh conveyors.

After collecting the data, the SCORPION® Software (SV8) Food Safety Module simplifies the calculation of lethality and then generates a comprehensive report displaying cumulative log reduction.  By combining this ease of measurement with robust data capture, the SCORPION® 2 system makes it simple to optimize your process while meeting food safety standards.

Other Parameters the Profiling System Can Measure

In addition to temperature, the SCORPION® 2 Data Logger can be used to explore more oven variables, earning far greater value from your investment.

Heat Flux

Oven heat flux is the best indicator of oven performance during baking in terms of the product. Many bakers use oven heat flux profiles when attempting to produce the same product on two different lines. The two lines will produce the same consistent product when the heat flux profiles match. The SCORPION® 2 Heat Flux Sensor is designed to measure convective and radiant heat fluxes at product level and display the results in Btu/hr·ft2 or W/m2.


Products passing through a thermal process interact with the moisture in the environment. The moisture often comes from the product itself and represents a delicate balance that affects finished product quality in many ways. Bakeries all over the world rely on the SCORPION® 2 Humidity Sensor, which measures the absolute moisture content of the thermal environment in both heating and cooling processes.

Air Velocity

In a radiant oven, the airflow comes from the moving conveyor, the exhaust system, and natural combustion air currents.  In a convection oven, the airflow comes primarily from the air distribution plenums.  Measuring the oven air velocity with the SCORPION® 2 Air Velocity Sensor will help you spot airflow differences between baking zones and unwanted air currents at the entrance or exit of the oven that result in inconsistent baking.
