Why is Cremmjoy the better, safer way to make soft serve?
Cremmjoy soft serve and slush machines deliver premium-quality frozen desserts and beverages while eliminating most of the downtime required by traditional machines. Conventional soft serve machines all use an outdated freezing process and must be frequently taken apart, cleaned, and sanitized to prevent contamination—costing operators $10,000 or more per machine each year in labor, cleaning supplies, and wasted product, and the downtime during cleaning prevents sales.
Cremmjoy uses a patented freezing process and specially designed disposable packaging that keeps the liquid mix separate from the machine’s mechanical parts. This removes the need for disassembly and cleaning, saving operators thousands of dollars annually and allowing machines to keep serving product with no downtime. Cremmjoy machines also let operators switch flavors and product types—ice cream, frozen yogurt, or frozen beverages—in just minutes.
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 $10,000 or more per year per machine and the downtime during this process prevents revenue generation.
Cremmjoy uses a revolutionary, proprietary, and patented 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!
