Dry ice pellet machine

Dry ice pellet machine

The dry ice pellet machine is mainly to compress the liquid carbon dioxide through high pressure into a very high density of solid dry ice pellets, and the dry ice pellets diameters can be adjusted by changing with different extrusion dies.



The dry ice pelletizer machine also can be named dry ice pellet machine, dry ice granulator machine, and so on, which is a piece of solid CO2 processing equipment for making dry ice pellets. The structure of the dry ice pelletizer includes the inlet, outlet, compression box, hydraulic system, feed pipe, solenoid valve, motor, exhaust pipe, extrusion die, electric cabinet with PLC control screen, etc. The raw material for making dry ice pellets by this dry ice pellet maker is mainly liquid carbon dioxide. According to different working capacities, we can design this machine with more than one outlet head for large-scale production of dry ice pellets.

When we inject the liquid carbon dioxide into this dry ice pellet machine inlet, the oil hydraulic press will press the liquid CO2 quickly and extrude them with a certain shape. The dry ice pellet machine has high working efficiency in making dry ice pellets, which can be designed with many types and models. And the dry ice pellet s’ diameter ranges from 3mm to 19mm. The output of this machine ranges from 50kg/h to 1000kg/h.
