Thermal Profiling in the Baking Process to Improve Bakery Profitability

Eager to improve the profitability of your commercial bakery? Conduct thermal profiling of your baking process and make adjustments that will help you achieve superior products.

The heat transfer experts at Reading Thermal,  headquartered in Sinking Spring, Pennsylvania, have been studying, measuring, and understanding the commercial baking process for over 25 years.

By connecting our different smart sensors and sensor arrays to the SCORPION® 2 Data Logger and passing them through the oven with your product, the measurement system can capture the four main baking parameters: temperature of the environment (including the temperature of both the air and the oven belt surface), heat flux (energy transfer), humidity and air flow (velocity).

What We Can Measure

Connecting smart sensors and sensor arrays to the SCORPION® 2 Profiling System and passing them through the oven with the product, enables the measurement system to capture the four main baking parameters:

Temperature (air, band and product core): Oven temperature impacts oven-spring, drying/dehydration, and color formation during baking. Insufficient or excessive heat can also lead to unwelcome changes in texture and taste. The Scorpion® 2 Temperature Sensor Array measures the temperature at product level, in fixed positions across the conveyor, and delivers a precise picture of temperatures from side-to-side and end-to-end.

Air flow (velocity): In a convection oven, the airflow comes primarily from the air distribution plenums.  In a radiant oven, it comes from the moving conveyor, the exhaust system, and natural combustion air currents.  Measuring oven air velocity with the SCORPION® 2 Air Velocity Sensor is crucial because airflow will influence the texture, firmness, coloration, and baking time of the final product. The profiles will help you spot airflow differences between baking zones and undesirable air currents at the entrance or exit of the oven that can cause inconsistent baking.

Heat flux (energy transfer):  Certain product characteristics are defined by the amount and type of heat applied during the baking process. The differences explain why one oven bakes differently than another. And analyzing and controlling these differences is critical to understanding how the finished characteristics of your products will be affected.  The SCORPION® 2 Heat Flux Sensor measures radiant and heat fluxes at product level and displays the results in Btu/hr·ft2 or convective W/m2.

Humidity: This is the amount of water vapor in the air. As your products bake, they use the available moisture in your oven. Without humidity, the quality and texture of your products will not turn out as expected. High oven humidity can lighten the crust color of baked goods and prevent it from burning. Lower humidity typically results in crustier bread. Global bakeries trust the SCORPION® 2 Digital Humidity Sensor, to accurately measure the absolute moisture content of the thermal environment in heating and cooling processes.

The Reading Thermal SCORPION® 2 profiling system and data logger provides industrial bakeries with information they can use to make reliable data-based decisions about their baking process and improve bakery profitability.
