Heat Treatment in Soft Serve Machines: The Ultimate Guide for Businesses

What is a Heat Treatment?

Heat treatment is a feature added to a soft-serve or milkshake machine  to reduce the frequency of thorough cleaning through heating the mix hopper to  66°C (151°F) for 30 minutes at the end of each day. This process destroys microorganisms, ensuring the hygiene and safety of the products served.

Unlike a regular soft serve machine that requires complete disassembly and cleaning by hand every 3-5 days, a machine with heat treatment allows you to stretch those cleanings to 14 - 28 days before needing to disassemble and deep clean.

These machines are equipped with advanced monitoring systems. Temperatures in the mix hopper, the freezing cylinder, and the glycol coolant are closely monitored and displayed. Should the machine fail to maintain the required temperatures or if it's not cleaned as scheduled, it automatically locks out, preventing operation until proper cleaning or maintenance is completed (we talk about the pros and cons of this below).

Why Choose Heat Treatment for Your Business?

  • Less Cleaning, More Serving: Unlike traditional soft-serve machines that need to be taken apart and cleaned every 1-5 days, heat treatment freezers only require disassembly and cleaning every 14-28 days. This reduces the daily maintenance labor and time costs considerably.
  • Enhanced Safety and Consistency: These machines benefit fast-food chains, restaurants, and shops with novice staff by ensuring consistent quality and health standards through automation and safety features.
  • Cost-Effectiveness and Mix Preservation: By reducing the time and resources spent on cleaning, these machines are cost-effective in the long run. You are also not removing and wasting mix every cleaning, which further adds to the cost efficiency.
  • Advanced Monitoring and Record Keeping: With built-in microprocessors, these machines keep records of system failures, which can be accessed by inspectors or operators. This feature aids in troubleshooting and maintaining standards.

Why Heat Treatment Might Not Be A Fit Your Business?

  • Risk of Operational Disruptions Due to Lockout Feature: This safety mechanism is designed to ensure the machine operates within safe hygiene standards, but it can lead to operational disruptions if not managed properly. A Lockout can be triggered for reasons like low mix levels, preventing the heat treatment cycle and leading to mix spoilage and the need for a full manual machine cleaning. 
  • Limited Suitability for High-Fat Mixes: These machines are optimized for low-fat ice cream products (3–5% fat). Using higher-fat mixes (>8% fat) risks over churning and butter granule formation (buttering out) due to continuous agitation in the hopper, restricting the range of products that can be efficiently made.
  • Higher Upfront Cost of The Machine: The upfront cost for machines with heat treatment is generally higher. For instance, the C717, which includes heat treatment, can cost approximately $8,000 to $10,000 more when purchased new, compared to the C713 without heat treatment.

 

 

Is Heat Treatment Right For Your Business? 

Heat treatment is a sophisticated feature for the ice cream service industry, offering numerous benefits in terms of hygiene and operational efficiency. With careful handling and attentive maintenance, these machines can be a valuable asset to any ice cream service business, balancing high efficiency with stringent hygiene standards.

Whats Slices Concession's Opinion? 

"For franchises or quickly growing fast food chains/shops, integrating heat treatment can lead to a substantial boost in profitability and efficiency. Like most things of course it's not a one-size fits all and could be overkill for a small or highly artisanal ice cream shop or restaurant."
