The better, safer way to make soft serve.

What is Cremmjoy?

Cremmjoy soft serve and slush machines are designed to deliver the safest-to-eat, premium quality ice cream, frozen yogurt, and frozen beverage products to consumers with virtually none of the downtime for disassembly, cleaning, and sanitizing required by conventional soft serve machines.

Cremmjoy vs. The Problem with Conventional Machines


All conventional soft serve machines currently on the market are virtual clones, using a 180-year old process for freezing the mix. These machines make good frozen products, but all need to be regularly disassembled, cleaned, and sanitized to prevent microbial and allergen contamination. For a standard 2 flavor machine, this cleaning process can cost operators $6,300 or more per year per machine and the downtime during this process prevents revenue generation.


Cremmjoy uses a revolutionary, proprietary, and patent-pending freezing process and consumable packaging to contain the liquid product mix from the initial reservoir through dispensing. This innovative process and packaging keeps liquid from touching any mechanical components of the machine, and eliminates the disassembly, cleaning and sanitizing process for the operator, saving thousands of dollars in operating costs per machine each year. Without the downtime, Cremmjoy machines can continue to dispense product, increasing revenue opportunities. Cremmjoy machines are also versatile with the ability to change between flavors and mix types (ice cream, frozen yogurt, and frozen beverages) in minutes!
