Pressurized Milkshake Freezer

A Pressurized milkshake freezer is one that is equipped with mix pumps that transfer the milkshake mix from the mix hopper to the freezing cylinder. While the mix is pumped into the freezer, a controlled amount of air is added to the product. This air creates pressure, which is then used to force the milkshake from the cylinder while dispensing. Typically this creates more overrun than gravity freezers.

 Gravity Milkshake Freezer

The mix in a gravity milkshake freezer is fed by mix feed tubes instead of mix pumps. As the name suggests, the milkshake mix is fed through these tubes by gravity into the freezing cylinder. Gravity milkshake freezers typically serve the product at a slightly warmer temperature and with lower overrun.

The Stoelting o112 milkshake machine (pictured) is a great option for locations with limited space, looking for a countertop shake freezer that still do high volume with quick recovery times.
