Dry ice Pelletizer | pellet Machine


The Dry Ice Pelletizer Machine also can be named dry ice pellet machine, dry ice machine and so on, which is a piece of solid CO2 processing equipment for making dry ice pellets. 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.

Working principle of the dry ice pellet machine

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 the liquid carbon dioxide. According to different working capacities, we can design this machine with more than one outlet heads for large scale production of dry ice pellets.

When we inject the liquid carbon dioxide into this dry ice pelletizer 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.

  • Dry ice pellet machine SL-50-1

This model SL-50-1 of dry ice pellet machine is a well-designed type, which mainly to turn the liquid CO₂ into the dry ice pellets or cylindrical shape. The diameter of the final dry ice granules ranges from 3mm to 16mm. This model is the smallest one for making dry ice pellets because it’s motor power(3.7kw) is small and its output is accordingly small. Its yield ranges from 50kg/h to 60kg/h.

>>> Operation Manual for Dry Ice Pelletizer Model SL-50-1

  • Dry ice pellet maker SL-100-1

SL-100-1 model of dry ice pelletizer is slightly bigger than the SL-50-1 in the overall dimension and weight. And it’s motor power is about 5.5kw so that it’s working capacity is big. Its yield ranges from 100kg/h to 120kg/h, which almost equals to the double output of the model SL-50-1 per hour.

  • Dry ice pellet machine SL-200-1

This model of dry ice pellet machine is a little different from the former two models in the outer shape. We can see that its hydraulic cylinder is outside its shell so that it is more convenient to maintain and repair. The diameter of the dry ice pellets from this machine ranges from 3mm to 19mm, and the diameter of the dry ice granules can be adjusted by changing with different molds. The yield of the model SL-200-1 ranges from 180kg/h to 200kg/h.

  • Dry ice pelletizer SL-300-1

The SL-300-1 model of the dry ice pelletizer machine is similar to the SL-200-1 in structure and the outer shape. The biggest difference between these two models is that the latter has a bigger yield which can reach 300kg/h. Besides, it’s motor power is 15kw which is also bigger than the SL-200-1 model. Same as the SL-200-1 model, this model of dry ice pellet machine also has one outlet and the diameter of the final dry ice pellets ranges from 3mm to 19mm.

  • Dry ice pellet machine SL-200-2

This model of SL-200-2 has two dry ice particles discharging outlets and it’s motor power is 15kw so that this model has a larger working capacity which is twice as much as the model SL-200-1. Its yield ranges from 360kg/h to 400kg/h. The diameter of the final dry ice granules also ranges from 3mm to 19mm, and we can also make dry ice pellets with different diameters by changing the molds.  

  • Dry ice pellets maker SL-300-2

The dry ice pelletizer of model SL-300-2 also has two discharging outlets in structure. This model has an hourly yield between 450kg and 540kg, which is twice as much as the SL-300-1 model can produce per hour. It needs motor power with 18.5kw. The final dry ice pellets are mainly used for making dry ice blocks and dry ice cleaning.

  • Dry ice pelletizer SL-300-4

In pursuit of greater production of dry ice pellets, you can choose the following two models of dry ice pellets maker. The model SL-300-4 needs the motor power of 37kw and it has 4 discharging outlets. The diameter of its dry ice granules also ranges from 3mm to 19mm. Its yield ranges from 900kg/h to 1080kg/h, which is 4 times as much as the SL-300-1 model or double of the model SL-300-2 can make per hour.

  • Dry ice pellet machine SL-600-2S

Same as the model SL-300-4, this model of dry ice pelletizer also has a large output, and its yield can reach more than 1000kg/h. It’s motor power is also 37kw and it also has 4 dry ice granules discharging outlets. When the dry ice pellets are made, they can be further processed into dry ice blocks or used for dry ice cleaning, or they can also be preserved in the dry ice heat preservation box.
