Gravity Machines
Gravity machines use the force of gravity to pull the product into the freezer cylinder.
Gravity equipment is fed through a bin on the top of the machine called the hopper. From there the flow of product is controlled by gravity via a tube.
Pressurized Machines
Pressurized machines use pumps to pull the product mix into the freezing cylinder.
Pressurized equipment gives the operator total control of the product mix and overrun.
If you're thinking about opening a frozen dessert or ice cream store then you'll need to consider what type of equipment to purchase to make your product. When it comes to mixing and dispensing ice cream you have many different choices on individual machines but essentially there are two types of mixing and dispensing equipment pieces that you can choose from, pressurized or gravity. Knowing the difference and how it affects your finished product is important to the success of your business.
The main difference between these types of machines is how the product gets pulled into the freezing cylinder and how much overrun you can generate. As the name suggests, a gravity machine uses gravity to pull mix into the chamber while a pressurized machine uses pumps. In the video above, Rob gives a fundamental explanation of what overrun is and how it affects your finished product.
