How Do Slush Machines Work?

As the sun gets hotter, our craving for something cold starts to set in. In 1958, we received the answer to our prayers when the first slush, the Icee, was invented. Since then, slush treats have taken over thanks to the invention of the slush machine.

But how do slush machines work to deliver us these refreshingly cool sweet treats?

Read this slush machine guide to learn more about these incredible inventions.

What Is a Slush Machine?

Slush machines use frozen ice and a little flavoring to create everyone’s favorite summertime treat. Unlike other drinks, slush machines put the ice crystals directly into the beverage, so you don’t have to worry about ridiculous ice cubes.

There are actually two types of slush machines:

Automatic

Automatic slush machines will measure the flavor and ice for you, making the job completely simple. All you have to do is add the right flavor to the right jar, and viola — yummy slush treats in no time!

Manual

These old-school machines need a little more help. You have to add the right portion of flavoring and ice yourself using the levers on the machine. Only the best slush makers could master the perfect slush on a manual machine.

How Do Slush Machines Work?

The most important part of a slush machine is its cooling system. This is what turns the flavoring mixture into a yummy frozen treat.

A component called the evaporator turns refrigerant, or the stuff that keeps things cold, from a liquid into a gas. Because of this reaction, the liquid syrup is then cooled to a perfect 3-degrees Celsius. At this temperature, slush begins to form.

Slush won’t freeze solid thanks to the delicious ingredient known as sugar. That’s right, sugar crystals act as an anti-freeze, preventing the water molecules from sticking together.

Because sugar is so critical, the ratio of water to syrup must be perfect.

Slush machines also include a mixer. This moves the slush around, helping to ensure every part of it is at the perfect temperature. This movement also helps keep the slush from freezing solid.

How Long Do They Take to Freeze?

Each slush machine is a little bit different.

Most machines freeze in less than an hour. The newer, more efficient machines can freeze in as little as 20 minutes.

If you’re buying a slush machine, be sure to check the freeze time.

Slush Machine Tips

If you’re considering buying a slush machine, make sure you take good care of it. Some great slush machine care tips include:

• Use the right ratio
• Clean your machine regularly, at least once a week
• Don’t use it until you fix it

If your slush machine is looking a bit worse for wear, make sure you get the proper repairs and maintenance done before using it again. This will prevent further damage, making sure you can produce slush treats all year round.
