What to Look for in Dry ice Machines


A dry ice machine is a device that makes dry ice from CO2 gas. The gas is compressed by a piston and the resulting high pressure causes it to change from a gas into a solid state. The solid CO2 then falls through a tube into the collection chamber where it freezes into small pellets of dry ice.

Machine Operation:

In its operation, a CO2 tank supplies the high-pressure gas to the dry ice machine’s compressor. The condenser cools the pressurized gas into liquid form before it enters the condenser. The liquid passes through an expansion valve, where it expands into a gas. This expansion allows the temperature of the gas to drop below zero degrees Celsius (32 degrees Fahrenheit). As this happens, it freezes into solid CO2 in the form of tiny pellets known as “dry ice.”

The dry ice pellets are collected in an insulated container known as a hopper or bin. When they’re ready for use, you can simply scoop them out with tongs or dump them into your container by hand.

Key Features of a Dry Ice Machine

Dry ice is extremely cold, at -109.3 degrees Fahrenheit. When dry ice melts, it turns directly into carbon dioxide (CO2), that’s why they are useful at a commercial scale for industrial or medical use.

The following are some of the key features of a dry ice machine:


The compressor is an important component of your dry ice machine because it stores compressed carbon dioxide which is then used to convert water into liquid or solid form. It also provides pressure to push out the gas from the storage tank into your delivery system.


The exchanger helps you maintain precise temperature control by converting heat into mechanical energy which then goes into producing dry ice.

Feeder hopper

This is the storage area where the ice is stored before it goes into the machine. The hopper can be made of stainless steel or polypropylene plastic. It is important that the hopper has a tight-fitting lid and is easy to clean and sanitize.


The controller controls the operation of the machine, including temperature, pressure, time, and humidity levels. It also monitors input and output temperatures. The controller may have an LCD display with buttons to set up cycles, turn on/off power, and start/stop production. A separate display screen shows current production rate and cycle time remaining for each product being made by the device.

Water supply line

This provides water at a specific temperature to the evaporator so that it can produce ice at its maximum efficiency level without any mineral build-up inside the evaporator tubes or freezing up of those tubes causing damage to them or even halting production completely until they are cleaned out manually (not recommended).


It is important to note that the dry ice machine needs to be set up in a place where it can be used for a long period of time. If you need to move your dry ice machine frequently, then you will need to buy one with wheels and a handle for easy transportation.

The next thing that you need to do is to ensure that there is enough space in the room where the dry ice machine is going to be placed. The size of the dry ice machine will determine how much space is required. In addition, ensure that there are no obstacles around where your dry ice machine will be located so as not to obstruct its performance.
