Desired outcome

Dehydration is routinely employed as a cooking process by the food and beverage industry. It uses significant amounts of energy and results in substantial lost heat to the atmosphere in the form of vapor clouds.

The presence of atmospheric air, up to 30% by mass, in the air-steam reduces the possibility of waste heat recovery. As a non-condensing gas, it remains in a thin insulating layer at the condensate surface; this layer increases the partial pressure of the air and considerably reduces the heat transfer efficiency between the waste heat (steam) and any recovery medium. Separating the air from the steam significantly enhances the waste heat recovery opportunity.

We wish to improve their waste heat recovery systems by implementing innovative technology to separate the desirable waste steam from the air-steam mixture.

Details of the Innovation Need

A successful technology will:

  • Be able to separate air from steam in a multiphase mixture (steam and air mixture with air content of up to 30%) at a continuous flow of up to 10,000 kg/hr.
  • Respond quickly to sudden variations of 0.3% - 5% per minute in throughput to meet changes in production rates of the primary cooking process.
  • Continuously monitor air and steam inputs and outputs with instruments that can provide 4-20 mA output signal at ±0.1 precision.
  • Have a hygienic design.
  • Be constructed of materials which will not leach out toxic compounds.
  • Be suitable for use with acidic flow.

Technologies that can perform the separation at atmospheric pressure are preferred.
