Commercial Slush Machine Types

Slushy, or granita, machines are incredibly versatile, allowing you to blend frozen coffees, cappuccinos, lemonades, smoothies, and even cocktails. If you are running an upscale resort, frozen mochas and cocktails are sure to be crowd-pleasers. If your business is more centered on families and youth, frozen lemonades, smoothies, and other frozen treats will score high with your guests.

  • Ideal for bars and resorts
Cons
  • Employees must create the mixture and pour into the machine

How Do Granita Machines Freeze the Product?

Whether you have a pourover or autofill machine, the product flows down from the hopper into a freezing cylinder or barrel, and a rotating device called an auger circulates the beverage inside the tank as it freezes, causing the "slushy" consistency. When the mix has frozen to the desired consistency (some machines allow you to adjust this), your drink can be dispensed from the front of the machine.

Knowing how many slushies you need to produce for your ice cream or snack shop relies entirely on how many people you plan to serve.

Products to Serve in a Slushy Machine

From a classic slushy to a frozen margarita to a blended milkshake, there are plenty of delicious beverages a slushy can make.

Traditional Slushies/Granitas

A traditional slushy is a blend of water, ice, and a flavored mix. More sugar means a slower freeze time, but not enough sugar will result in a coarser beverage because the ice crystals are larger. This could result in your machine freezing up, so it's important to experiment with the ratio of water to sugar to keep your machine running properly and your drinks tasting great.

Frozen Cocktails

Some machines are equipped to handle alcoholic products. However, it's important to read up on your local food service laws because some areas don't allow you to add liquor to the machine. Alcohol also slows freeze time, so you may produce less slushy per hour if liquor is added. It's also important to check the manufacturer's user manual to ensure that there aren't any special maintenance requirements or procedures for frozen cocktails in the machine.

If you'd like to offer your customers frozen cocktails but don't want to put liquor in the machine, you have other options. Simply blend up a neutral base granita, and as you draw beverages from the tank, add whichever flavoring of liquor you want and mix it with a beverage stirrer. This option also allows you to offer a variety of different cocktails rather than being limited to one specific drink per tank of granita.

Dairy-Based Products

Certain machines are certified to serve dairy-based products, such as blended milkshakes, frappes, and hot chocolate. Serving dairy-based frozen drinks will require a more involved cleaning routine with your unit and it should be emptied, cleaned, and sanitized every day to prevent buildup and contamination. A unit must be approved to use dairy ingredients, so check the manufacturer's manual to determine if your machine is qualified to serve dairy.

Slush Machine Considerations

In addition to the type of product you'll be serving and the size capacity of the machine, there are other factors to consider like where you will be placing the unit and how to care for it.

ADA Compliant

A factor to consider when purchasing a slushy machine is who the principal operator will be. If you are contemplating a self-serve machine designed for front-of-house action, it's important to accommodate all of your potential customers. You can easily do so by purchasing a machine that is compliant with the Americans with Disabilities Act. Most ADA-compliant machines have extra-long dispenser handles, which permit easy operation and are more user-friendly.

The Right Voltage

On slushy machines, a higher voltage generally means a faster recovery time.

For example, a 220V machine will yield more product than a 120V unit in a shorter period of time. However, just because the voltage is doubled doesn't mean that the output is also doubled. The output of your machine will vary widely depending on the manufacturer, the type of unit you purchase, and other factors like the type of recipe you're making and whether or not it contains alcohol.

When trying to calculate the voltage you'll need, it would be helpful to ask yourself a couple of questions:

  • How many slushies am I planning to produce daily?
  • Does my location have the correct electrical outlets for the desired voltage?

If you are unsure of which machines will accommodate your situation, you can look at the Specification Sheets and product descriptions of the units you are considering for further information.

Care and Cleaning

It's important to regularly clean your slushy machine, as the mixing tank can harbor bacteria and other pathogens if left unattended for too long. As a rule of thumb, most machines should be cleaned at least once per week. If you use milk in your recipes, though, you will want to clean the machine at the end of each day.

In addition to the tank and the moving parts within, also be sure to clean the drip tray beneath the faucet. It's easy for this area to become slimy and unsanitary as condensation and extra mix run out of the faucet.

Water Filtration Systems

Water filtration systems block contaminants to help keep your beverages clean, safe, and tasting great! They help to extend the life of your equipment by consistently preventing sediments, cysts, and scale from clogging the internal workings of your machines. Plus, the filtration makes your beverages clearer and more visually appealing. By purchasing a water filtration system, you can be sure that your vibrant, colorful slushies taste as wonderful as they look.

Running a Profitable Slushy Business

Selling slushy products can be highly lucrative. Whether it's your primary source of profit or you'd like to add it to your existing menu, it's important to have the right supplies and know-how to maximize your returns.

Auto Fill and Maintenance Kits

Purchasing an auto fill kit or maintenance kit can save you money in the long run if any inner components of your machine have a malfunction. Some manual fill machines can even be converted to auto-fill using these kits.

Slushy Mix

Jug mixes can be added manually or attached to a pump dispenser. They have a re-sealable cap to ensure freshness. Or, try making your own slushie mix to create gourmet flavors and stand out from the competition.

For higher product quantities, you may want to consider a bag-in-box mix. You'll be refilling your machine less while producing more beverages at a time. This is also the most economical way to buy syrups. Check out how much you can save using Carnival King 5 gallon bag-in-box syrups!
