Together with liquid CO
2 gas, SS
Foundry is also involved in the production of dry ice. Dry ice is
nothing but solid carbon dioxide. It is formed by letting down the
pressure of liquid CO
2, through a nozzle or other
bottleneck. An amount of the liquid CO
2, passing through the
nozzle, vaporizes and sub cools the remaining fluid. Hence, it is
born-again into snow like particles which is known as "Dry Ice".
Dry Ice is has a wide range of application which are as follows :
- With the help of Dry Ice, heat sensitive chemical reactions are
carried out.
- Hardening of blades etc. is done with dry ice.
- Shrink fitting is done with the use of dry ice for closer
tolerances.
- Decreased downtime through cleaning in-place.
- Elimination of equipment damage.
- Faster and more thorough cleaning.
- For food preservation and transportation, it lowers the
temperature and the dry ice evaporates.
- Low temperature / cryo grinding etc.
Process for Making Dry Ice:
Types & Plant Sizes
We make use of different types of dry ice machines for different
applications. We can supply dry ice making machines in two varieties:
- Cylindrical blocks
- Rectangular blocks
Generally block size is 5" dia x 12" length. These blocks
weigh around 7-8 kg. The Dry Ice Plant sizes ranges from 45 kg/hr to 300
kg/hr. Dry ice machines making small size nuggets of 1.0" - 1.5"
are also available.
Dry
Ice Machines & Storage
We go for custom orders as well, irrespective of the sizes. For very
small requirements of our clients, our company offers a small
inexpensive gadget which can make dry ice from a CO
2
cylinder. By using this, dry ice snow can be manufactured at the rate of
5-10 kg/hr. However the drawback in such cases is that the "block"
is not firm and compared to dry ice obtained from regular CO
2
plants, efficiency is less as. This equipment is ideal if requirement is
small and occasional.
We also supply machines to our clients
- To cut blocks
- To put dry ice on continuous conveyor belts of food/medicine
- To fill CO2/dry ice in medicine/chemical/food
packages.
- Special freezer for temperature below -45°C is also
available.
Our company also make FRP-Polyurethane insulated boxes and canvas
bags with polyurethane sheets. These are used for storage of dry ice.
Having excellent insulation properties, these storages keep the dry ice
for longer time with minimum evaporation losses.
