Tips for buying a soft-serve machine

When opening a frozen yogurt store, the soft-serve machines will be the largest single expense. A good machine is critical to serving good product. There are several basic things you need to know about frozen yogurt machines. This information may seem overwhelming, but given that you might spend $50,000 on your soft-serve machines, the investment of your time will be worth it.

The Basics
To make frozen yogurt you’ll need a commercial grade soft-serve machine (soft-serve machines and frozen yogurt machines are the same thing). Here are the basic components of the machine:

  • Hopper – the area where you pour the frozen yogurt mix.
  • Freezing cylinder – this is a small shaft that sits horizontal inside the machine. The mix drips from the hopper into the freezing cylinder where it freezes.
  • Beaters – these are inside the freezing cylinder and they spin around to keep the mix from freezing solid. They also help whip air into the machine and make a nice creamy product.
  • Front plate – this is the piece that goes on the front of the machine with the handles. It also includes the opening where the frozen yogurt is dispensed. Most machines have a star shaped design where the product comes out – giving the frozen yogurt the look we all recognize.
  • Overrun – this is the air that is in the frozen yogurt mix. Air is critical to making a nice creamy product. Without overrun, the product will come out dense, icy, and won’t taste right. Visit the Training page on the Nanci’s website for a video on how to control overrun.

Machine Sizes
There are several different sizes, but for our purposes we’ll break it down into two types – floor model and counter-top model.

Floor model – these machines go all the way to the floor and are on rollers. They are either medium or high capacity and usually require 220-volts, but not always (see the section on electricity). They usually have two flavors and a twist (although they can come in a one-flavor model). For frozen yogurt shops, this is usually the best option.

Counter-top model – these machines sit on a counter or cart. They are usually low capacity to medium capacity. They are available with one flavor one two flavors and a twist. These machines can be a good option as an add on to an existing concept, like a sandwich shop.

Electricity
Most medium to high-capacity frozen yogurt machines require 220 volt electricity, although some are 115 volts. In either case, they will require different outlets than your standard home electrical outlet. They will also require higher amps than normally. Be sure to check with an electrician to see what will be required and how much it will cost.

Gravity versus Pump
This refers to how the mix gets into the freezing cylinder. With a gravity machine the hopper is at the top of the machine. The mix is poured into the hopper and then gravity pulls the mix into the freezing cylinder. With a pump machine, the hopper is pressurized and the mix is pumped into the freezing cylinder. The advantages to a gravity fed machine is that they cost less and are easy to fix. The advantages to a pump machine is that you have complete control over the amount of air you put into the final product. This can affect the quality of your product and the cost.

Gravity machines can put in up to 45% air and pump/pressurized machines can put in up to 100% air (which means equal parts mix and air).

Air Cooled versus Water Cooled
The motors in soft-serve machines produce heat and need to be cooled. The two methods for cooling are either air cooled with a fan or water cooled with pipes that run water through the machine to cool it. Overall, we recommend air cooled because they are less expensive to install and need less maintenance.

Air cooled machines don’t require any additional investment when installed, and they can be less expensive to operate (depending on your electricity costs versus water costs). Water cooled require installation of a water system, which can cost $15,000-$40,000. Water cooled machines make less noise and produce less heat. You may save on utility costs if your water costs are much lower than your electricity.

Soft-Serve Machine Companies
There are several companies that manufacture and sell frozen yogurt machines. Some are made in the United States and others are made in other countries, like China. Prices on floor models range from $5,000 to $15,000. The machines will vary in quality, warranty offered, and production capacity. The right machine for you depends on your constraints (like cash or the ability to finance) and your goals (how many machines you need, the type of concept you are doing). There isn’t always just one right answer for what machine you should buy. Contact a frozen yogurt expert at Nanci’s and we can discuss it with you. We don’t sell machines, so we’re a great neutral, third-party to talk with.

If you decide to buy machines at the low-end of the price range, make sure to machines are made with good materials and parts. For example, all machines are made with stainless steel, but steel has different grades of quality. Some machines that are made with the low-quality stainless steel can rust and cause many problems.

Also, keep in mind that regardless of the brand of soft-serve machine you purchase, you’ll want to make sure you have good access to service. All machines break at some point, and you’ll need a good technician that can work on them.

In your negotiations with machine companies be sure to ask for free in-person training and free parts (such as o-rings and machine lube). Some companies offer free Nanci’s product to off set the initial costs of the machine.

Machine Maintenance

The start of a new year is aSLX400En excellent opportunity to take a look at your soft-serve machine and make sure that it is primed and ready to go for 2016! This includes not only continually cleaning your machine, but also proper lubrication and checking for any wearable parts that may have seen better days. Annually is a good time to remove the side panels and visually inspect for leaks from the motor casing and loose connections. You should also take the temperature of the hopper and freezing cylinder on standby and auto modes and compare that to what the machine is saying to check that it is calibrated correctly still. Ensuring that your machine is running properly and that it is consistently producing a quality product throughout the year will be essential to your customer base and overall margins at the end of the year.

Cleaning your machine is an important aspect of maintenance to help the longevity of your machine. Get in the habit of cleaning your machine at least once a week. This process includes running a sanitizing agent through the machine, effectively killing any bacteria that may have grown or built up.  If your machine goes weeks without being thoroughly and properly cleaned harmful bacteria may build up and could potentially lead to spoiled product.

Once the sanitizing agent is mixed with water and poured into the hopper of the machine, put the machine on the wash cycle and allow the product to cycle through the machine for a period of 5 minutes. This will allow the sanitizing agent to reach all of the nooks and crannies of the machine, killing any remaining bacteria. Be careful not to enable a feature on the machine that willPacket x2 freeze down the product, as the process of the water freezing could severely damage your machine. Every other week, we recommend pulling all of the machine components such as the face plate and the freezing cylinder shaft and let them soak in hot soapy water as well. The process of cleaning the machine is simple in its procedure, and it can be done any employee if they are properly trained how to do so. Check out http://frocup.com/product/sanitizer-packets/ to get started today!

Lubrication is another key technique in keeping your machine running for an extended period of time. The main component of the machine that requires lubrication is the back end of the shaft that sits deeper inside the freezing cylinder. Pull this out and pull off the rubber gasket that fits on the end of it. Lubricate around the square piece at the end of the shaft and place the gasket back onto the lubricated piece. When you pull out the freezing cylinder shaft to clean it is an excellent time to lubricate it as well. Tubes of all-purpose lube are also sold at http://frocup.com/product/machine-lube/.

There are various wearable machine parts that can become damaged and wear down over time. The scraper blades, for example, attach to the shaft on the inside of the freezing cylinder wear down and don’t scrape the edge of the cylinder with the exactness and precision that they once did. This leads to the freezing of product on the edge of the cylinder and can lower the overall quality of your product. These scraper blades are different with each individual machine company so make sure the blade is rated for your model of machine before buying replacements. You can find various machine springs, seals, and O-rings as replacement parts at http://frocup.com/product-category/supplies/.

Look for general brittleness or the wearing down of plastic parts as key points in replacement. Replacing parts before they go out will save you from costly damage to other components of the machine and keep you from having a non-functioning machine during your peak season. Understanding your machine is very important in maintaining it over time. Pulling out all of the main components and familiarizing yourself with them as you sanitize, lubricate, and replace any necessary parts will help you to keep your machine running strong throughout 2016 and beyond.machine breakdown diagram

Two Magic Numbers for Frozen Yogurt

The correct temperature setting on your soft-serve machine is critical for making a good frozen yogurt product and for extending the life of your mix. Every frozen yogurt shop owner should have a good food thermometer like this one: https://frocup.com/product/digital-thermometer/

Use a thermometer to check the temperature in the hopper (the reservoir where you pour the mix) and the temperature of the product when you dispense it from the machine.

Magic Number #1

Hopper Temperature = around 35 degrees F (between 34 to 39 degrees)

The hopper temperature is critical for keeping the product fresh The temperature in the hopper should be under 40 degrees F. Any warmer and the product can go bad. It should also be warmer than 32 degrees or else the product in the hopper will freeze. If you see the product freezing in the hopper, just raise the temperature a degree or two.

Magic Number #2

Finished Product Temperature = 17-19 degrees F

The temperature of the product when it is dispensed should be between 17-19 degrees F. This would also be the temperature of the freezing cylinder. Because Nanci’s Frozen Yogurt use pure fruit sugar, the temperature for our mixes needs to be a little lower than for cane sugar mixes. A sugar mix might come out stiff at 22 degrees, but Nanci’s mixes are better at around 18 degrees. This can easily be adjusted on your machine – just consult your manual or contact the manufacturer if you need help.

If your product ever comes out wet, soupy, or melted then you need to lower the temperature. Frozen yogurt should come out stiff, creamy, and frozen (not wet). It’s amazing what a difference a couple of degrees makes.

Which Ice Cream Cup Size is Best?

cups 10 14 16 black  

So, which size cup should I be using in my ice cream store?

When faced with the decision of what size ice cream or frozen yogurt cup to use in your store, several options probably come to mind. Cup sizes range anywhere from a small 4 ounce (oz) size cup to an enormous 32 oz cup. Surely there has to be an optimal size to make it easier on you as the business owner and to satisfy your customers. Nanci’s experience with soft-serve over several decades has lead us to just the answer: the 10 oz cup and the 14 oz cup. These are two new shapes pioneered by Nanci’s and available exclusively at FroCup.com. They are a perfect fit for self-serve customers! Both the new 10 oz and the new 14 oz cups have a fun and modern light swirl design around the outside and are made of a strong, durable paper material that doesn’t tear or seep at the seams. So why are these new sizes better than what you’re currently using?

10 oz – Small

This new shallow/wide shape is perfect for families with children. As you can see in the picture above, the 10 oz cup fills quickly and, due to the height of the cup, the yogurt spirals above the top to give it a nice and full look where the yogurt seems to be brimming to the top. As the yogurt melts and the customer digs in, the width will catch any running liquid or toppings from making a mess. Since it has the same width as a standard 16 oz cup, you can actually fit both your small and large cups in the same cup holders if desired.

According to our research, we have found the 10 oz cup is the ideal ‘small size cup’ to carry in your store. It has enough volume to hold yogurt for a customer who may just want a few bites – perfect for kids. It is the best of both worlds – wide enough to handle all the toppings your customer wants to add yet shallow enough to still look full. This perception of a full cup is key to a customer making their way back to your store in the future; you want them to feel as if they are getting the best ‘bang for their buck’.

14 oz – Large

The 14 oz cup is a deeper cup. It has a large volume and can hold a full pound of yogurt. And it has the same wide diameter as a standard 16 oz cup so it can easily handle all the toppings your customer wants to add. What makes the 14 oz superior to the 16 oz is the shorter height of the 14 oz. As you compare the 14 oz and the 16 oz cups, you see a clear difference in the presentation of the yogurt. The yogurt in each cup is the same amount, however it stands up much taller in the 14 oz and it looks much fuller. The 16 oz cup drowns the yogurt a bit, and the customers may feel they aren’t getting as much product as they really are getting. A full 16 oz cup of yogurt is a lot even for those with the biggest appetites and we have found that it is often not necessary to have that large of a cup in stock. A hungry customer will fill the 14 oz cup to a swirl above the rim and be satisfied with their eyes, tummy and wallet.

The 10 oz and the 14 oz are the perfect sizes whether you are just starting up a new shop, or you have owned a shop for years. FroCup has 4 vibrant colors to choose from: orange, blue, green, and pink.  The swirl design is popular among both young and old alike. Also available is a convenient one-size-fits-all clear dome lid for the 10 oz, 14 oz, and 16 oz cups. It’s easy to make the switch and increase your store’s customer satisfaction and perceived value.

16 oz, 20oz and Larger

The 16 ounce, 20 ounce, or larger cups give you more options for your frozen yogurt shop. You can use these cups for ice cream, gelato, soft-serve, parfait, or really anything. Paper cups are a great option for both dine-in or take-out customers. Ice cream cups are also available in a range of materials – from thick, durable paper to plastic. Cups for ice cream sundaes or gelato parfaits can even include lids to keep the toppings and sauces contained until the moment of serving. Ice cream cups are really versatile, and as a result you’ll likely want to stock up on more than one type. These larger sized ice cream cups allow your customers to take larger amounts home. You’ll want to make sure you have lids available.

How to buy ice cream shop cups at wholesale pricing?

Nanci’s Frozen Yogurt sells cups, lids, and spoons in a variety of sizes, colors, and materials on FroCup.com. This includes brands like UNIQ and desirable options like bio-degradable cups and eco-friendly spoons. You can try our best selling color cups in a variety of sizes including 4, 6, 8, 10, 12, 14, 16, and 20 oz options.

The Secret Ingredient for Amazing Frozen Yogurt

Close your office door and make sure no one is listening because I’m about to share with you the secret to making amazing frozen yogurt…ready…here it is…AIR. That’s right – one of the key components of smooth and creamy frozen yogurt is to have air or overrun in the product. If the product comes out icy and dense that means there isn’t enough air in the mix. This is especially important with natural frozen yogurt mixes.

All frozen yogurt machines have a hopper and freezing cylinder. The hopper is where you pour the mix, and the freezing cylinder is the horizontal empty cylinder behind the handles where the mix is frozen and the air is whipped into it. Inside the freezing cylinder there should be at least 30-40% air. This gives room for the product to expand and create a nice, creamy consistency.

Getting air into the product will depend on the type of soft-serve machine you have. Here is a quick breakdown. For more detailed instructions and help contact us at 1-800-788-0808 or info@nancis.com. You can also visit our Training Page for a howto video on adding air into the product.

Pressurized or Pump Soft-Serve Machine

These machines pump the product into the freezing cylinder with the exact amount of air you want – up to 100% air. Pump machines allow for you to set the precise amount of air. Consult the operators manual for your machine to find out how to adjust these settings.

Gravity Soft-Serve Machines

With gravity machines, the mix is poured into a hopper on the top of the machine and gravity pulls the mix into the freezing cylinder. On a gravity machines you need to manually set the air, for a maximum of 45% air.

One very important piece on the machine is the carburetor tube or air tube. The carburetor tube is a skinny tube – usually stainless steel – that you insert into the intake hole in the bottom of the hopper. Once inserted, the top of the tube sticks up out of the product allowing air to get down into the product. All carburetor tubes have some way to shut off the product intake – either by flipping the tube over or by closing off the intake hole using a sleeve that fits around the tube.

Here are the 6 steps:

  1. Pour the frozen yogurt mix into the hopper without the carburetor tube and wait for the bubbling from the intake hole to stop. The freezing cylinder is now full.
  2. Insert the carburetor tube to stop the product from flowing into the freezing cylinder.
  3. Turn on the soft-serve machine and wait for it to freeze down and shut off.
  4. Keeping the intake closed, dispense 8-10 ounces of frozen yogurt into a clean cup. This product can be put back into the hopper.
  5. Wait for the machine to cycle off then open the air intake either by flipping the tube around or sliding the sleeve on the tube.
  6. The overrun is now set and the product should come out smooth and creamy. As long as you leave the air tube in place it will stay this way.
Another important factor in dispensing a great product is the temperature on the frozen yogurt coming out of the machine. Nanci’s mixes are best served at 17 degrees F.
