Potato Blanching Comparison: Hydroheater vs. Sparger
Energy Comparison: Hydroheater vs. Shallow Tank Sparger in Blanching Process
|HEATER REPLACED||Shallow tank sparger|
|BENEFITS||Reduce steam consumption and increase energy savings|
These estimates are based on the results of a tank heating test conducted at Hydro-Thermal's in house lab. A 500 gallon tank was heated from 50°F to 200°F using a sparger, then again with a Hydroheater. The following data is from that experiment.
The estimated energy required from a sparger compared to a Hydroheater is determined by taking the loss rate determined in the attached experiment and applying it to the energy load determined above. In the last range of temperatures in the experiment, raising the temp from 169°F to 200°F took 2.57 times as much steam using a sparger as it did using a Hydroheater. Because the actual blancher tank is not as deep as the tank used in the test, this is conservative.
