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/g°C versus water = 1 cal/g°C),
- 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.
