Open Innovation Challenge:

Reduced conversion cost of liquid milk to dried milk powder

Reason for Seeking External Partnership:

Current spray drying methods are capital intense and require high energy usage/operating costs. Milk is comprised of 87+% moisture, which typically requires large separation, evaporation, drying steps to reduce moisture to 3.5% in the milk powder.

Scope of Solution Space:

  • What is ‘in’: Different processing technologies to convert liquid milk to powder, final milk powders (skim, buttermilk, whole) should match current compositions and properties; alternate uses for the separated and/or evaporated moisture; evaluation of high concentration methods / processes
  • Must-haves: total cost of ownership not to exceed a conventional liquid-to-dry powder system for equivalent scale or throughput
  • Nice-to-haves: more environmentally-friendly, sustainable solution in conversion and/or in the usage of the liquid stream(s).

Innovation Solutions Not of Interest:

Must not produce powder that has measurably different functional characteristics (solubility, wettability, dispersibility, flowability, bulk density, etc.)
