Technology Description

Figure 1 shows a research version of the Argonne-developed system for making an ice slurry. The produced slurry has the following attributes:

• Small ice particles (<0.1 millimeter),
• High ice concentration (>50 weight percent),
• Biologically compatible carrier liquid (saline solution plus other ingredients),
• Several times the cooling capacity of water (ice = 80 cal/gºC versus water = 1 cal/gºC),
• Excellent fluidity and storability obtained by altering ice particle size, shape, and surface roughness by using patented methods, and
• Slurry that can be pumped nearly as easily as water through very small, properly designed delivery devices.

The slurry production equipment in Figure 1:

• Produces slurry on-demand (< 2 min processing time),
• Is portable,
• Uses disposable sterile ingredient modules,
• Has a controllable dose and delivery rate,
• Is capable of continuous or intermittent delivery,
• Can maintain protective cooling for > 2 hours, and
• Includes special delivery injectors developed for various medical uses.
