Actuator Options Available

Hydro-Thermal's heaters utilize a Fisher reverse-acting diaphragm actuator (“fail close”). Generally coupled with a filter/regulator and a Fisher DVC 2000 or a DVC 6200 positioner that converts a 4-20 mA DC input signal to pneumatic output signal to the actuator. For high vibration applications remote mount positioners are available. Alternative positioners are available depending on unique processing conditions or upon request. Please contact Hydro-Thermal for more details.

Applications for Food and Beverage Processing


Technical Papers

Enhanced functionality of pea-rice protein isolate blends through direct steam injection processing

Washington State University students researched the effects of direct steam injection on pea-rice protein.

To view the abstract and download the full article, click here.


A summary of their findings:

  • The study demonstrated that using Hydro-Thermal’s Direct Steam Injection (DSI) technology, that the functional properties of Pea and Rice Protein isolates are enhanced while not degrading, but maintaining the amino acid composition and overall protein quality.
  • The high shear and temperature in combination with high pH resulted in creation of modified proteins that become more hydrophilic and improve solubility. Therefore, allowing food processors to have components that disperse better and more easily.
  • DSI also improved emulsifying activity, foam stability, and oil holding capacity. All of which are crucial for food companies requiring natural methods of creating stability in complex food systems that customers constantly demand.
